Wild Food, Prices, Diets and Development: Sustainability and Food Security in Urban Cameroon

This article analyses wild food consumption in urban areas of Cameroon. Building upon findings from Cameroon's Comprehensive Food Security and Vulnerability Analysis (CFSVA) this case study presents empirical data collected from 371 household and market surveys in Cameroonian cities. It employs the UN Special Rapporteur on the Right to Food's framework for understanding challenges related to the availability, accessibility, and adequacy of food. The survey data suggest that many wild/traditional foods are physically available in Cameroonian cities most of the time, including fruits, vegetables, spices, and insects. Cameroonians spend considerable sums of their food budget on wild foods. However, low wages and the high cost of city living constrain the social and economic access most people have to these foods. The data also suggest that imports of non-traditional staple foods, such as low cost rice, have increasingly priced potentially more nutritious or safe traditional local foods out of markets after the 2008 food price crisis. As a result, diets are changing in Cameroon as the resource-constrained population continues to resort to the coping strategy of eating cheaper imported foods such as refined rice or to eating less frequently. Cameroon's nutrition transition continues to be driven by need and not necessarily by the preferences of Cameroonian consumers. The implications of this reality for sustainability are troubling.


Introduction
To complement staples such as corn, wheat or rice, Cameroonians that live near forested areas typically collect wild plant roots and leaves, fruits and nuts from trees, and hunt wild animals, fish and insects [1,2].Foods hunted and gathered from forests contribute to food security through providing people with calories, animal and plant proteins, and essential minerals and micronutrients-especially iron and iodine, and also vitamins A, the Bs, C, D and E. These are essential micronutrients that not only create a more secure and varied diet, but also help to combat the effects of "hidden" hunger or micronutrient deficiencies [3][4][5].While the economic value of "hidden" harvests can vary, these foods make significant and consistent contributions to Cameroonian livelihoods [6][7][8][9].Also "hidden" at present are the contributions wild edible species make to national food balances (import-export sheets): the principal guides used to inform policies on food aid, trade and the domestic and international declaration of food crises [10].With the routine "underestimation of wild foods comes the danger of neglecting the provisioning ecosystems and supportive local knowledge systems that sustain these food chains" ( [11], p. 2913).When policies in forested countries obscure or neglect the routine consumption of highly nutritious edible local plant and animal products gathered from surrounding environments, they perpetuate the "hidden" status of these foods [12][13][14].
Much of the food security literature describes wild food consumption as a coping mechanism or adaptive strategy for increased household security when times are bad [15][16][17].This common narrative depicts the gathering and consumption of wild foods as a reliable option when social or economic access to food at the market has been compromised either by environmental or income shocks.This account of wild food seems more likely in rural areas where there is greater access to and reliance on the surrounding environment for gathering wild foods.Researchers have conducted numerous studies on wild food utilization in rural areas [18][19][20].However, in urban Cameroon, wild foods make a significant contribution to diets and to dietary diversity.Cameroon's food system is not only comprised of domestic agricultural (cultivated) products (including cassava, maize and plantain) and imported foods (such as rice and wheat), but also hunted and gathered forest foods (such as green leafy vegetables, spices, fruits, insects and forest meats).The engagements of city dwellers with wild foods are worthy of serious scholarly and food security attention.
Subsequent to the global food crisis of 2008 these so-called hidden foods have increasingly become foods that are only accessible to the wealthy or to the masses on special occasions.Food price inflation in many cases pushed locally produced and available wild foods out of the reach of average citizens.Average consumers nonetheless consider it culturally appropriate and desirable to prepare and eat these foods on a more consistent basis.This is not surprising considering the extent to which these foods contribute to the routine cuisine ( [13], p. 4) Since the crisis, average urban Cameroonians have had to turn away from local wild products they would prefer to eat out of necessity.
This shift is disturbing given the limited state of knowledge about food in urban Africa.Crush and Frayne state that "nowhere is there any systematic attempt to… understand the dimensions and determinants of urban food security" across the African continent ( [21], p. 532).They and others have identified a dearth of research on urban food security in sub-Saharan Africa [21][22][23].In this research deficient context, even less is known about the contributions wild foods continue to make to the food baskets of urban dwellers.
To address calls for a more systematic analysis of urban food security in Africa this article is guided by a central research question: what are the contributions of wild food products to food security in urban centers of Cameroon in the aftermath of the global food crisis?To answer this question, the article draws upon the UN Special Rapporteur on the Right to Food's understanding that food security challenges require a multidimensional approach [24,25].While the framework advanced by Olivier De Schutter is not uncontroversial, it provides a coherent entry point for the assessment of wild food contributions.This approach emphasizes the physical availability of wild foods; the social, economic and physical access people have to wild foods; and the nutrition, safety and cultural appropriateness or adequacy of these foods in Cameroonian cities.This exercise consequently employs De Schutter's analytical dimensions to further knowledge about a seriously under-studied food security challenge.It is a highly convenient approach vis-à-vis wild foods, despite the fact that it is still hotly contested [26].
De Schutter has emphasized the over-arching consideration of sustainability in his work on each dimension of food security, and this emphasis is especially germane to this study.While some wild foods are now cultivated in urban areas, their hunting or gathering can have positive or negative impacts on the sustainability of forests, leading to their degradation, or alternatively, to their sustainable management [27].Moreover, in urban Cameroon, the availability, accessibility, and adequacy of food can be enabled and compromised in unusual ways.Take for example a health scare linked to frozen imported chicken in the mid-2000s.As chicken consumers fell ill, civil society advocacy groups launched campaigns to highlight the food safety issues involved in the freezing and thawing of this "new" source of relatively cheap protein [28].Without a reliable cold storage chain, this attempt to make frozen chicken parts available and accessible for a good price in cities raised questions about the safety and adequacy of this "cheap" meat.De Schutter's approach enables the comprehensive treatment of similarly "unique" issues.
In light of the lack of research attention on urban Africa and on food security challenges in Central Africa, this article aims to contribute to nascent conversations on the linkages between wild foods and food security in cities in the Congo Basin.After the 2008 global food crisis the Comprehensive Food Security & Vulnerability Analysis (CFSVA) tool was drafted by the World Food Programme (WFP) to identify and assess food security situations in countries where the WFP is active.The CFSVA process generates a document that describes the food security status of various segments of a population across various parts of a country or region [29].This article draws on the findings from Cameroon's CFSVA baseline study supplemented with interview and survey data gathered during fieldwork in Cameroon from 2010-2012 for a case study assessment of wild food consumption in Southern Cameroon.Through working with De Schutter's dimensions and applying them to the analysis of interview and survey data, it is clear that urbanites in Cameroon continue to rely upon wild foods, or at least continue to hope to rely on wild foods.Many spend more than 25 percent of their food budgets on wild products.
The next section reviews in more detail the literature underpinning the article's focus on wild food and food security.In the third section the country context and research methods are described.Section four presents the results and provides preliminary answers to the central question outlined above.Section five concludes the paper with a summary of key findings.

Getting Wild: The Continuum of Human-Plant Interaction
Through a literature review, Carolan notes numerous "turns" in agro-food studies that he describes as being less about "a specific theoretical framework as it is around a general way of doing agro-food scholarship" ( [30], p. 1).He engages with the notion of "wild" as being a part of the theoretical terrain of "wild" in food research and encourages researchers to "get wild" in the spirit of discovery ( [30], p. 15).Thus, rather than engaging in doing things "that tame…the future of agro-food research appears to lie increasingly in multiplication and of creating more entanglements not less" ( [30], p.2).He states "…humans…are, "co-journeying" with food and agriculture across multiple spatial scales and institutional settings" ( [30], p.5).This journey is continually remaking agricultural and food relations through the engagement with the natural environment and human culture [31].It is with this spirit that the article engages with the term "wild".
Wild is not a simple concept, it can "evoke a sense of individualism and a bourgeois ethic of freedom," and can imply something that needs to be tamed ( [30], p. 5).Similarly, environmental historians and geographers have found that "wilderness is not necessarily a fixed and objective concept" ( [32], p. 204).Rather it is one that is formed on the basis of individual perceptions, expectations and cultural values.The environments in which wilderness might be found have an "objective ecological reality, and usually one that largely excludes obvious human modification" [32,33].What makes wilderness "wild" rests very much with the individual, and her or his emotions, values and experiences [31,34,35].From this, a series of "wildernesses" can be identified.These "multiple perceptions of wilderness", that are peculiar to particular groups can be collected, organized and mapped ( [32], p. 204).Just like there are many types of "wildernesses", there are many types of "wild".Thus wilderness and wild have both an ecological and a human perceptual meaning.
For paleoanthropologists, ethno-botanists, and ecologists, the accumulation of plant-based knowledge follows from repeated observation of the effects certain plants have on the formation of human culture [13,36,37].The terms wild, cultivated, and domesticated actually represent points on a continuum of increasing interference with the natural ecosystem that defines the human-plant relationship.At one end of the continuum are the "entirely wild" which grow outside the man-disturbed habitat [38].Thus the term wild often applies when a plant's habitat does not include secondary (human disturbed) habitats such as open areas, thickets, roadside, old fields, edges of fields etc. [39].At the other end of the continuum is noticeable human intervention such as "selective harvesting, transplanting, and propagation by seed and graft" [13,39].This explanatory framework has been around since the 1960s and "emphasizes the continuities between foragers' reliance on wild species for "food procurement" and agriculturalists' reliance on domesticated species for "food production" [13,38,40].However, in tropical forest "even disturbed secondary rainforest might first appear to be pristine" [41,42].Darrell Posey, for example, working with the Kayapo people of the Brazilian Amazon, has shown that certain "wild" plants along paths through "pristine" forest have been in fact planted by the Kayapo as a source of food, medicine and other resources.It was not until biologists began talking to local people, that they found they had been misled by their own definitions [43,44].
Foraging and farming across the world are "overlapping, interdependent, contemporaneous, coequal and complementary" [11,38].Within these systems there are no easy distinctions between "wild" and "cultivated" foods.While food research and policy tends to consider these types separately, many local communities rarely make distinctions between foods from the forest or the field [5,45,46].This complexity is the result of particular local knowledge that is then "encoded into norms, rules, institutions and stories, and this forms the basis for continued adaptive management" of food systems and environments over generations [11,[46][47][48].The continued availability of these plant foods depends on the maintenance of synergies between farming practices and wild biodiversity [49,50].In turn, food agro-biodiversity is inextricably connected with cultural heritage [45,51,52].To focus on food and culture, as well as food and dishes always "reflect the regional identity of people, ethnic groups and communities, and the use of wild food plants is an example that exemplifies local knowledge or traditional ecological knowledge" [5,20,53].Ethnographic and empirical findings from the survey show that in southern Cameroon, these specific foods simply "come from the forest" or "come from the bush".Cultivated foods "come from the fields."Viewed in this way, it is the forest that provides the "wild foods" and these include edibles that are not only plants [54].
The role and value of forests to food security is grossly underestimated [1,9,55].Some research suggests that forest-dependent people who live in or near forests tend to be politically weak and hold very little power in decision-making processes relating to the management of forests ( [55], p. 1388).This is reinforced by forest-dependent people's geographic distance from urban centers where political alliances that might favor forest conservation tend to be formed and maintained [56].The Food and Agriculture Organization (FAO) estimates that globally, over one billion people continue to rely on wild foods to meet their food needs [57].Pimental et al. has found that "healthy forest ecosystems are essential to world food security because they (i) directly provide food to large numbers of people; (ii) produce products and employment that enable people to purchase food; (iii) [and] protect the environment [in ways] that help…the productivity of forestry and agriculture" ( [1], p. 111).
In research on Cameroon the distinctions are further complicated by the concept of non-timber forest product (NTFP) or non-wood forest products (NWFP).NTFPs are "all biological materials other than timber, which are extracted from forests for human use" ( [58], p. 161).This literature has tended to emphasize this definition, however this definition includes non-edibles.When NTFPs are mentioned in the literature on Cameroon, the focus is often on quantifying yields sold in local markets [59][60][61][62][63] and measuring their economic importance through focusing on rural employment and income [64][65][66][67].Making the distinction between all materials and edibles is important for an urban food security study as urbanites are purchasing these foods for home consumption in markets.The past and current research lacks a critical element of the NTFP trade in Cameroon: their use by urban residents, the ways they feature in urban diets, and their contributions to food security in urban areas.
The global food crisis has sparked renewed attention to wild or "hidden" foods for food security [68][69][70].These foods are being recognized for their contributions to dietary diversity and nutritional security [69,71].It is encouraging to highlight international interest and renewed attention on biodiversity and the sustainable use of these significant crops across Africa [68,[72][73][74].It is well known that these forest foods make invaluable contributions to households' food security [11,12,14,45,[75][76][77]. For example, turning back to the CFSVA for Cameroon the report describes higher levels of food security in the forested region of the country than in the Sudano-Sahelian north [78].While this can also be attributed to changing weather and unrest in neighboring countries that border northern Cameroon, forested foods in the south help to compliment agricultural products and imported food.Similarly, findings from a study of the nutrient composition of "bush meals" from Cameroon's northern regions stress the fundamental role of wild food for nutrition and their sustainable use for increased food security [79].

Urbanization and the Availability, Accessibility and Adequacy of Wild Food
Increased urbanization (as a result of rural to urban migration) across the African continent is an important factor that expands the size of local, urban wild food markets [21,80].This movement and the ensuing food trade creates a new type of consumer who, unlike rural inhabitants, has to buy wild products rather than gather them [61].Urban individuals (and households) are generally net food buyers who rely on their income for their food security, spend a large proportion of households' budgets on food, and have little access to other safety nets like agriculture or land to ensure food access in times of crisis [21,81,82].Consequently, the buying and use of wild foods in this environment becomes more about food choices, personal preference and household budgets than the wild "famine foods" touted in the literature [68].Globally, people purchasing food to meet their daily needs dominate the urban scene [21].Poverty is no longer found only in rural areas but in urban areas as well.That being said, food insecurity is probably higher among the urban poor than among the rural poor and this was demonstrated during the food price crises in 2008 [15,16,25].
More specifically, Cameroon is considered a highly urbanized country by sub-Saharan standards.A recent 2010 estimate from the United Nations World Urbanization Prospects suggests that Cameroon's urban population is 58% of the total population [83].Despite strategies aimed toward reducing rural poverty, urban poverty is somewhat ignored [21,81].Further, economic growth in Cameroon is not on target and the country is not on target for meeting the Millennium Development Goals [84].Urban poverty in Cameroon is best described as poor access to adequate infrastructure, a lack of social services and income poverty.In the literature on urban Africa, it is often explained that the high costs associated with "urban shelter, transport, health and education undermine the ability of the chronically poor to access sufficient food" ( [21], p. 536).All things considered, Toye predicts that the economic impact on development will be "hardest for low-income urban households in developing countries that are net importers of food" ( [85], p. 761).The literature on food in urban Africa highlights factors beyond actual production and availability of food by drawing attention to the social and economic access to food and the realities of balancing household budgets in a deteriorating urban environment [86].
The knock-on effects of the 2007/2008 food crisis "drew attention to the vulnerability of the world's poor, especially the urban poor" ([87], p. 350).The perception that food will always be available in cities was altered for many in 2008, when the food prices peaked and reached levels not seen since the 1970s [88].The world's poor suffered the greatest blow as food prices rose to unattainable levels, rations decreased or disappeared, and frustrated people took to the streets in protest [89].In particular, high global oil prices in 2008 sparked strikes and riots of taxi drivers in Douala and Yaoundé, Cameroon that halted the movement of food between cities [90].Not only was food more expensive, it was more expensive to move it around the country.In these cities, the strikes are remembered as a time of low stocks in the markets and food shortages at home.The budget of low-income households is disproportionately skewed so that 50%-60% of household income is spent on food.However, the literature on food price shocks and volatile prices suggests that the food price crisis should not be seen as changes in people's income alone.Volatile food prices are a common feature of low to middle income economies where local markets are not regulated to protect the poor [91].Food prices remained volatile over the subsequent years and remained above 2009 prices.For example, the CFSVA for Cameroon notes that food prices have remained higher than before the price crisis of 2008 [78].Compared with the last five-year average, prices for "maize and cassava increased by 18%, rice by 33% and plantain by 39%" ( [78], p. 7).Governmental measures adopted after the food price crisis and subsequent food riots in major urban areas, "managed to bring food inflation down to an estimated 1.2% in 2010" ( [78], p. 7).While these measures assist with accessing staple foods, prices for local vegetables and wild foods remained high.The literature on food crises features the intersections of the availability of food and accessibility of that food.While it is assumed that food will always be available in cities, the food riots made it clear that food will not always be accessible.
The food price spikes of 2007-2008 and 2010-2011 have had far reaching effects on urban residents generally and especially on food choices within households in urban areas.Evidence from Swan et al. suggest that vulnerability to high food prices is likely to be associated with the type of staple food consumed, the ability to substitute cheaper foods, trends in income and the degree to which households rely on the market for food [92].When food prices increased in 2008, Swan et al. learned from the Central African Republic, that households adopted damaging coping strategies.People in their study were reported purchasing less expensive foods with limited nutritional value, eating less preferred foods and reducing the diversity of their diets.Their findings suggest that food price shocks increase the risk of micronutrient deficiencies ( [92], p. 111).Many urban poor people have little room to maneuver as coping mechanisms decrease food security.When food prices rise, households can: buy less food; buy lower quality food; reduce portion sizes; reduce meal frequency and buy less variety of food.These coping strategies affect nutrition and health.Generally, these strategies involve a shift in diets from sorghum, millet, maize and root crops to rice and wheat which are often highly processed, imported, subsidized and available cheaply [22].Cereals such as rice, wheat and maize are the basis of the urban diet and because they are internationally traded they can leave the urban poor even more exposed to global price fluctuations [93].A dietary transition most often occurs in cities where these "cheap" foods are most accessible and where high food prices exclude the poor from accessing healthier food options or traditional foods.The term "nutrition transition" was coined to describe the process that happened many decades ago in developed countries but is now occurring in developing countries [94].It marks a shift in diet from simple staples high in fiber to a greater intake of saturated fats, sugar and refined foods [95][96][97].The transition accelerates the incidence of dietrelated non-communicable diseases [98].
As global food prices rise, this transition is more pronounced.In their 2007 study, Sharma et al. found that food composition data for Cameroon are severely limited [98].Their study provided, "for the first time, the calculated nutritional composition of composite dishes commonly consumed in the urban and rural areas of the Central Province of Cameroon" ( [98], p. 476).Their findings suggest that rural Cameroonians eat a more diverse diet and engage in more physical activity than their urban counterparts.The "rural diet is more or less based on the traditional staple foods, while the urban subjects incorporate more modern foods into their diet" ( [98], p. 153) These include pasta and rice and beignets or deep fried balls of sweet dough made with wheat or cassava.The goal of these studies was to use these findings for "nutrition interventions aimed at modifying commonly consumed composite dishes to improve dietary intake" as nutritionists in Cameroon are noting alarming rates of obesity, diabetes and other diet related conditions [98][99][100].Findings such as these are important because they demonstrate at the micro-scale of bodies the ways that the broader political economy impacts food choices, households' food security and ultimately public nutrition and health.The literature on coping strategies and nutrition transition relies on such dimensions as accessibility and adequacy.When the conditions are enabled that make food less accessible the adequacy of diets is compromised leaving households vulnerable to future dietary and health shocks [100].What we can take from this body of literature is that "food security strategies of the urban poor, and how these are thwarted or enabled" are crucial for studies on urban food security ( [21], p. 528).By using the three dimensions of food security outlined by De Schutter particular aspects of the literature stand out and drive this analysis forward.In light of neglected consideration of nutrient-rich foods in an urban environment and with this brief history and review in mind the methodology and results follow.

Methodology
Cameroon is an excellent territory for a case study of foods from the forest.Located in the equatorial and tropical regions of the Gulf Of Guinea, the South and East regions of Cameroon are located in the humid forest zone (HFZ) of the Congo Basin, and the Southwest region of Cameroon has been labeled a biodiversity hotspot [101,102].However, some researchers have claimed that information on food provisioning systems in cities in Cameroon is "sparse and often too incidental for the purpose of advanced research", an analysis of this "system needs to be built from the local level" [103,104].Therefore, this case study draws on empirical evidence the author collected during four separate research trips to Cameroon from July 2010 to December 2012.This study builds on the findings from Cameroon's CFSVA and the 2011 baseline survey of 6300 households from Cameroon's ten regions.From this CFSVA study, households responded to a questionnaire about their food intake, their sources of income, livelihoods and expenses, assets and various practices associated with strategies for survival [105].The findings from urban areas suggest that urban dwellers experience a greater level of food security than their rural counterparts.However their situation is greatly impacted by rising food prices, as urban residents have to purchase the food they consume.The survey also argues that in the capital city and regional capitals food insecurity is almost non-existent [105].Building on these findings, the present case study documents urban food security through focusing on wild food consumption in three cities in Cameroon: Buea, Limbe and Yaoundé to highlight the voices and experiences of the people in these cities.All three cities are located in the HFZ in Cameroon's Center and Southwest regions.These cities were chosen for in-depth qualitative research based on their locations within this zone where "foods from the forest" are primarily gathered and consumed.Etkin contends that diet surveys tend to ignore "wild plants" compared to dietary "staples".This is attributed to a "lack of understanding regarding which plants should be included in the "wild" category and the extent to which they contribute to routine cuisine"( [13], pp.4-5).But wherever the "consumption of wild foods has been accurately accessed, they emerge as regular and important elements of diet" [13,20,[106][107][108]).When taken into consideration more nuance of the food security situation in these cities can be described and assessed through the inclusion of these "hidden" foods.
The research design focuses on the sellers and buyers of wild food products in urban areas.The maps below identify the markets and sites this study concentrates on in each location.Within each city, markets were randomly selected based on criteria such as size, location, days of operation and identification of wild food sellers.Geographic Information Systems (GIS) points were collected to map the locations of the markets in each city.The first map (Figure 1) charts the locations of eight markets and four restaurants in Yaoundé where wild foods are bought and sold.The second map (Figure 2) identifies nine markets around Buea and Limbe where wild foods are bought and sold.Subsequently, these sites and the circles on each map indicate the proximity of households to markets that sell forest foods.While these points are not exhaustive, they mark the sites this study concentrates on.Using these maps, data was collected via participant observation and semi-structured interview surveys in English and French in both markets and households [41,[109][110][111][112][113][114].The surveys were conducted in both the wet and dry seasons.The author relied on the capabilities of research assistants who were competent in either English or Cameroonian Pidgin (for interviews in Buea and Limbe) or French (for interviews in Yaoundé the capital).Individuals were randomly selected in the market and asked to participate in the study.These included food traders in the market and customers looking to fulfill their food needs.Randomly selecting participants ensured diversity in the sample and allowed for an analysis of the particularities of urban sub-Saharan Africa food markets.
The households that were interviewed typically do their food shopping in the markets falling within a one to two kilometer radius from their home.Reasons given for choosing certain markets were: diversity of products, proximity to their home and price.Some markets have a reputation for particular food products and in all cities individuals commonly frequent more than one market to locate certain products.One woman in Yaoundé mentioned: "Huitieme for tomato and green condiments, garlic, Mokolo for big items and Mvog-Ada for meat, smoked fish, plantain and fruits."Designing the research in this way allowed for ethnographic insights into urban food markets, and also food purchasing patterns and trends of households [115,116].
The survey was field tested in each city for reliability.The interviews were guided mostly by open-ended questions, including: where do you do your food shopping?What percentage of your monthly income do you spend on food?What do you do when you don't have enough food, and don't have enough money to buy food?What foods do you need to feel food secure?During these field tests the survey became participatory as additional questions were added or omitted based on preliminary responses and input from participants [117][118][119].The questions deemed most sensitive were related directly to income and also to foods that were considered "rich" food or "poor" food.Questions about income were reduced to focus specifically on the portion of the household budget related to food.Framed in this way, participants were comfortable sharing portions of budgets without worry that a "tax man would come by."In Yaoundé 106 food traders and 127 households and in Buea and Limbe 64 food traders and 70 households participated.In total, this study is based on interview survey data from 197 households, 170 food traders and four women who run open-air restaurants: 371 participants in total.When factoring in dependents and household size, the survey includes 2,111 individuals.Participant observation in the food markets and also shopping and cooking with some households also inform the study.
Special attention was given to the types of wild foods consumed, if any, and the impact of food prices on households' budgets.Data was stratified by gender (male and female headed households) and income level (low, middle, and high).Qualitative measurements of food security include indirect indicators (e.g., asset ownership, social support networks, household size, and immediate circumstances), food coping strategies (e.g., household attempts to deal with times of insecurity through dietary changes, rationing consumption, establishing credit, drawing on social networks, etc.) and perceptions of acceptability (e.g., symbolic role of food and cultural appropriateness within the household) [120].A gender imbalance exists between men and women as regards the selling of food, food provisioning and cooking in households in the Congo Basin.This includes buying and cooking food, getting water from a public source in the city and also obtaining fuel (wood, gas, sawdust) to prepare food.From the survey, it was learned that women cook foods with their daughters, and sometimes sons, but their husbands do not assist in food preparation unless the wife is out of town or sick.Cooking at home is the predominant way of feeding the household as it is considered expensive to eat out.The households surveyed rely on domestic, public or community, together with stream and river sources for cooking and drinking water.Fuel sources for cooking range from firewood, gas, sawdust, coal and charcoal and while the cost of these items are factored separately into food budgets and because of the expense they are used frugally for cooking.
Survey data, transcripts and field notes from interviews and discussions were read and coded for emerging themes related to wild food consumption and relative levels of food security within and between households at different income levels.There was a particular focus on the perceived acceptability of these foods for meeting household needs.It uses textual and illustrative means to explain reasons for varying circumstances and experiences of engaging with wild food products.The author makes no claim from this case study that data are representative of the wider populations of these cities or quantitative rates of food insecurity in these cities.Instead, the data represents a snapshot into the lived and daily realities of food provisioning for residents of Yaoundé, Limbe and Buea.

Results
The results in this section seek to answer the central research outlined above in the introduction and speak to De Schutter's [24] three dimensions of food security: availability, accessibility and adequacy.
In terms of availability, wild foods do not fit into De Schutter's standard agricultural model.These foods do not necessarily require access to agricultural seeds, technological inputs, fertilizers or pesticides.The supply-side of wild food hinges on a different set of factors and production knowledge that influences availability such as seasonality, weather, harvesting or gathering and most importantly access to the forest.The climate in Cameroon's forested southern region is described as "four seasons equatorial" [121].This includes a clearly defined major dry season (December-May), followed by a short rainy season (May-June).The short dry season lasts from July-October followed by a high rainfall wet season (October-November) [122].What are noteworthy about the availability of wild food products are the seasonality of particular foods and the identification of peak periods of abundance and also scarcity.For example, due to seasonality, there are times when markets are full of safou.In June and July the deep purple fruit with avocado-colored insides are available by the piles in urban markets.In addition to being sold raw for home consumption, plums are also prepared on the roadside, by women fanning small fires, roasting the plum for a quick snack or meal on the go.Safou plums often replace maize roasted roadside as the seasons change.

All year
Protein, prepared from fresh, roasted or dried to be used in stews When there is scarcity, food traders or buyam-sellams (in Cameroonian Pidgin) named various reasons for low stocks of wild food in the market.Some traders say: "It depends on the season.There are periods when there is little harvest from the forest.There could [also] be shortages because of the weather or a rise in prices."Urban residents say the forest is too far away now so they do not go there as much as in the past to find food for their households and for sale.These same residents also suggest that the farm is more reliable than the forest for food harvests because the forest is changing.Other traders herald, "sometime the buyam-sellam don't find the products in the forest and if they do the Forest and Fauna officers [can] stop or arrest the buyam-sellam on the road."Interestingly, some traders mention that, "at times I hear that some people hide food to cause scarcity but this is difficult for perishable foods."These buyam-sellams highlight the difficulties in maintaining a reliable stock for the urban demand for forested foods.
Due to large scale logging, the growth in cities, decaying roads and voracious officers from MINFOF (Ministère des Forêts et de la Faune) or the police, many wild food traders are finding it less profitable to travel to the forest to gather food for the cities.This impacts the availability of these products.I often heard complaints from traders that their biggest problems finding food for the market are because of threats of seizure of products by officers or the bothersome possibility of paying bribes to ensure the food arrives at the market.The possibility of a shake down is most often an opportunity for corrupt officers to "chop" the earnings of gatherers and wholesalers, and not necessarily related to the traders going against a law.Efforts by the government to halt corruption are underway and may trickle down to roadside police.
The most notable wild foods found in urban markets are the spices (see Figure 3).Cameroonian cuisine combines the different regional staples (such as rice, yams, cocoyams, plantains, potatoes, cassava, maize and millet) with vegetables, fruits, and animal and fish products into a soup or stew.The staples are usually roasted, boiled, fried or pounded in a mortar.The most common are plantain, cassava and cocoyam, which when pounded takes on a gelatinous consistency as the starch breaks down [123].The resulting fufu accompanies one-pot dishes, such as ndole, eru or okok, achu vegetable, kwakoko with mbanga soup and mbombo djobi (or mbongo tchobi), among other local meat and fish dishes and are exceptionally popular ( [124], p. 139).Figure 3 identifies most wild spices available in Yaoundé during the wet season.These spices include various parts of a plant such as the fruits, the stone or pit of fruits, the bark, the blossoms and leaves and bulbs.These parts are dried and often ground into a powder or a paste.For example, the pit of the bush mango when dried and ground to a crumbly paste is added to stews as a thickener.The ground pit creates a slimy consistency, similar to okra that facilitates eating the stew with the accompanying fufu, which is eaten by hand.While many edible wild plants and other food products are regularly included in local food purchases, wild spices make up a significant portion of the household food basket and are inextricably linked to the food culture.These spices are components of recipes that are a part of traditional meals and the daily diet.Often I heard the argument, "if we do not have food from the forest, we cannot make our traditional meals and they are my children's favorite foods."Cameroon is made up of over 250 ethnic groups and the cuisine differs not only by ethnic group, but also by region [125].Foods from the forest are essential components for these dishes and the regional cuisine.They also provide important vitamins and minerals derived from dietary diversity that help to keep households healthy.The spices pictured (in Figure 3) are some of the spices, in various forms, that are available for these meals.

Over-Exploitation
Certain wild foods are in high demand and are considered threatened by organizations such as the International Union for the Conservation of Nature (IUCN) and the World Agroforestry Centre (ICRAF).To mitigate the effects of over-exploitation, some wild foods are undergoing cultivation, which is the process of growing and managing wild species through selection and adoption of desirable characteristics [126].The cultivation initiatives, for Gnetum, bitter leaf, njansang, country onion, and cane rat (Thryonomys) and snails help to ensure these foods are available in times of scarcity and inconvenience while also managing the damaging effects of overharvesting.These initiatives help to ensure their availability through sustainably managing the wild population to avoid over exploitation of the forest.One example is the wild leafy vegetable, Gnetum africanum, which is a climbing vine and can be successfully propagated.The leaves of the vine are edible and are sliced thinly, to help break down the tough leaves (Figure 4).Bundles of eru are available in city markets and results from the survey show that eru with waterleaf and fufu was overwhelmingly named as the household's most favorite dish.Eru or okok (as Gnetum is known in English and French Cameroun) was mentioned 914 times in the survey of 371 individuals.One woman confessed "If I don't eat eru I feel like I have not eaten".While cultivation efforts ensure that harvests are not depleting wild populations of the food products, the health benefits derived from consuming these foods and consumer demand make endeavors such as these worthwhile (see the section on adequacy below).

Accessibility
There is a confluence of factors that impact food accessibility for urban households.According to De Schutter, accessibility "requires both physical and economic access: physical accessibility means that food should be accessible to all people… economic accessibility means that food must be affordable without compromising other basic needs such as education fees, medical care, or housing" ( [24], p. 4).In terms of accessibility, the survey revealed that it is "not easy for the poor man in the city to eat."In this case, the individual was speaking about himself, but this quote exemplifies the experience of most city residents.From the data gathered in Cameroonian cities, the majority of urban residents spend more than half of their income on food-about 50%-75%.This does not leave much room in a budget of "other basic needs" as highlighted by De Schutter.What is remarkable from this number, is that 25% of the household's food budget is spent on wild foods.Figure 5 shows how food budgets are broken down by the total amount of income spent on food, and of the total percentage, the percentage of income that is devoted to wild food purchases.The seasonal variations suggest that more money is spent on wild foods during the dry season than the wet season.This can be attributed to a change in prices in the market, which is described below.
The prices listed below (Table 3) are based on measurements and quantities that vary between buyam-sellam and are difficult to estimate.These prices are directly out of the survey from households and traders, however, the quantities are difficult to compare across product, season and city.Prices and quantities are negotiated between the buyer and seller and can change remarkably from one sale to the next.This table is meant to provide some insight into wild food prices and is not definitive or exhaustive.What is notable from this price data is that there is a slight price difference between cities whereby Yaoundé is seemingly cheaper than Buea and Limbe for forest foods.Additionally, the quantities dramatically change between seasons and prices remain nearly the same.When it is the wet season, food traders describe a change in the amount of wild food they sell.During the wet season in Yaoundé 94% of traders claim they sell more as compared to 78% of traders in the dry season claiming they sell less.Reasons given suggest various urban trends such as an increasing urban population because clients are increasing and creating a rise in demand.Traders report selling less in the dry season, suggesting that "there is competition, sales are declining, business is difficult" and "the clients complain about the financial crisis and they reduce the quantity and the frequency of purchases".While all of these reasons are likely, one way to describe the fluctuations amongst sales between seasons is linked to physical availability: when there is scarcity or the perception of scarcity, some sellers raise their prices.When these foods are perceived to be abundant some traders lower their prices, making these foods more economically accessible.On the other hand, some traders in the context of abundance after the rainy season will leave prices unchanged.Instead, they will increase the quantity of foods they sell while keeping prices the same as dry season prices.The perishability of these foods often encourages traders to pursue this pan-seasonal pricing strategy.
In this context, when asked if eating habits change between seasons, all households said that "Yes they change.We adapt for each season.We eat what the vendors have that is least expensive and abundant in the market" and "During the dry season there are many shortages and we make do with what is least expensive.During the rainy seasons a lot of products are less expensive and are varied."This change in quantity impacts consumers in various ways.Food buyers are forced to change their food provisioning patterns between seasons as people report buying and eating less food during the dry season.When consumers reduce the quantity and frequency of their purchases in the dry season, the buyam-sellam have already decreased the size of the quantity that would be sold from the season before.A fluctuation in food intake on this scale has an impact on diet and health.One trader in Yaoundé remarked, "I think that they [my clients] eat less.They just look to eat, not to have a balanced diet."Seasonality is a major factor for food insecurity in urban areas across Africa and compounded by climate change, the struggle for calories could be greater in the future.
When asked the question: do you buy and consume wild foods in your household in function with the level of your revenues?Most women answered with a resounding no.Women in Yaoundé, Buea and Limbe assert that these are products we buy because we like to eat them.Most women mentioned, "They are not expensive.They are accessible to all and we buy them because they are necessary in the preparation of our meals."Taking this further, one women asserted, "we consume them only as a question of taste and want, (not need); these foods are a part of our culture it is only because of their flavor that we eat them."One single-woman with four dependents said "certainly we don't have enough money, but we eat more foods from the forest because we have adopted them in our eating habits."Identifying these foods as something that contributes to and enables a more robust food culture, the purchase of wild foods means something more than just buying and eating these foods.
When asked if food stability in your household is disrupted when there is scarcity or increased prices for wild food products, many participants in the survey answered with a resounding yes.The most common answer being: "our favorite household dish uses forest foods as its base and we use it as the principal condiment in certain dishes."Similarly, most women mentioned, "our eating habits revolve around these products."Other women mentioned the need to substitute food items and to change planned meals.Often this means abandoning the established diet and incorporating more cheaply available and often imported foods: "I would be forced to eat other products because when there is a rarity of NTFPs I eat other things like sautéed pastas."The effect a price rise of wild food has on diets does not go unnoticed, another woman revealed "I could no longer eat a balanced diet I will be forced to eat spaghettis [sic] and fried rice without my favorite condiments."Still another woman claimed "if some foods become rare we eat something else, they are important but we can do without them."The ability to substitute foods and have flexible food options are a feature of urban diets, but the frequency in which this needs to happen does have an effect on dietary diversity and health.
Before the 2007-2008 food crisis a common narrative from Cameroon was that imported products were generally more expensive than local foods and crops.These imported foods relied on more formalized trade networks than traditional organizations that managed production and distribution and were known to be cheaper ( [104], p. 189).When asked which imported food products are more available to you than local products, the greatest frequency in the response was rice, pasta, fish, and sardines.Households in Yaoundé described these products as being "available to everyone, they are less expensive than local products."In cities in Cameroon the food price crisis has had a strong impact on households' food security.In this case, there were also price fluctuations in the market for local food items and this can often influence and initiate an adjustment in food provisioning patterns.
A very revealing question from the survey highlighted a difference between cities as regards foods consumed in households in the last 12 months.As part of the survey, participants had four choices to choose from in their answer: we always have enough to eat and the kinds of foods we want; we have enough to eat but not always the kinds of foods we want; sometimes we don't have enough to eat; and often we don't have enough to eat.Results from this question show that households in Buea and Limbe have enough food to eat, but not the kinds of foods they want; whereas residents in Yaoundé say that sometimes we do not have enough to eat (Figure 6).There are a few ways to interpret the responses in Figure 6.Linguistically, there is a divide in Cameroon between the English-speaking western region and the rest of the French speaking country.Residents from Yaoundé, the French capital may enjoy lower prices and greater access to foods than their Anglophone counterparts.While the Anglophone cities are closer to the Francophone city of Douala, the main port for the region, than the capital, responses such as these could stem from the "Anglophone Problem" in Cameroon [127].This problem is "fundamentally institutional and economic" and is best described through the ways that "state power is exercised in a fractured polity… and how that power is used to benefit one group at the detriment of another" ( [127], p. 61).This problem has been well documented, see for example: [127][128][129].An investigation into price comparisons (Table 3) between cities and seasons showed that the prices for wild foods were slightly higher in Buea and Limbe than in Yaoundé.In this case, food substitution happens, but it is not always enjoyed.This has to do with the types of coping strategies adopted by many of these households.The differences found between coping strategies adopted in Francophone and Anglophone cities are explored in more detail below.

Strategies to Cope with Increasing Prices
The impacts of price shocks for commonly consumed foods initiated a host of coping strategies.When asked, what do you do when you do not have enough food and do not have enough money to buy food, women often say "we are used to it…" The demand for local Cameroonian food is high; however, accessing that food when prices are elevated is a challenge.When households do not have enough food or enough money to buy food, the most commonly named strategies include:  I manage with the little I have  I am stricter about how much food I serve and other than the children we only eat one meal a day  I make a cheap meal with rice and palm oil or garri (cassava) and water  I reduce the quantity of food I eat  I eat one or two meals a day  I harvest from my farm  I borrow from family, savings group, or merchant Statements such as these demonstrate how urban residents adapt to an unrelenting food security situation.In both Anglophone (31%) and Francophone (25%) cities residents say they "manage with the little I have".This can last for two days and happens often, at least once a month.The differences in strategies are apparent.In Francophone Cameroon some women mentioned eating cheaper foods more frequently such as fried rice, bread and braised fish by the roadside.They also talked about rationing food and buying and eating smaller quantities (20%).Reducing the number of meals eaten in a day was the most common answer for Yaoundé residents (28%).Reducing the number of meals was also mentioned in Buea and Limbe (23%).Whereas in Anglophone Cameroon, the two most common answers were: I borrow from family and relatives (20%) and I go to the farm to harvest food (20%).Borrowing from relatives was mentioned by only a few Francophones (9%) and harvesting from the farm was not mentioned.This can also be attributed to differences in urban food geographies [23].From these responses, it is safe to assume that most urban residents from the survey are living in a state of food insecurity as "secure access to enough food at all times" is not a statement that describes the current situation [130].
From these data, it can also be learned that eating less meals also means eating less at meals, eating lower quality foods, and eating cheaper options.Responses from the survey show that 54% of the individuals surveyed consumed only two meals a day (see Figure 7) and if these meals already include dishes that are of low quality and diversity, then nutrition is negatively impacted.This is in contrast to the findings from the CFSVA that show that 33% of individuals surveyed reduced the number of meals eaten a day ( [105], p. 7).The figure below shows the percentages of the reported responses and the number of meals eaten in a day.Compared to the CFSVA, these percentages show greater food security challenges in cities than was initially reported.
When prices for foodstuffs are elevated, women mentioned buying in smaller quantities, changing their menu, and making food every two days, for the following two days, based on what is affordable.Without proper cold storage, this strategy is somewhat delicate.When it comes to food prices, those with dependents say, "We still buy particularly what the children like."Other women noted that "I review my budget by not buying certain foods, we buy what is most important and we complain to the vendors so that they explain the situation."These women are forced to adapt.Statements such as: "we still buy but this messes up our budgetary plan a bit.There is an instability that exists" suggest that the food situation in most households surveyed is tenuous at best.When food prices have risen, the most commonly named foods to buy are: rice, dried beans, pasta, banana and tomato.When prices are low, foods commonly purchased include beef, pork chicken, bar fish, meat generally (and includes bush meat) and plantain.It is important to highlight the distinctions between these lists.The first list includes some foods that are imported and available cheaply, most often, these foods are not impacted by seasons.Having local foods such as banana featuring in this list is interesting because banana is a very ubiquitous tree crop throughout HFZ cities and is a cheaply available fruit.The latter list includes proteins (with the exception of dried beans) which are historically difficult to come by in forested regions [131].In cities in the forest zone, proteins are still relatively more expensive than the vegetables and staples that traditionally accompany them in dishes.The inclusion of plantains in this list illustrates barriers to access, as the cross-border trade in plantains with Gabon seems to be on the rise.Peppered throughout the market surveys from Yaoundé were stories about the Gabonese coming to the market to buy plantains, driving the prices up (3,000-7,000 FCFA for a bunch).Banana plantains are an integral part of home cooked meals across the sub-region.On the one hand, Cameroonian households have experienced the price rise as a price shock, forcing them out of the market for a staple food they would prefer to eat.On the other hand, "sharing" the plantain harvest with more affluent Gabonese was a boon for the plantain trader's business.
An increase in food prices is the main shock experienced by urban households, who buy more than 90% of the food they consume.Eating wild food is often touted as the mechanism to stave of hunger when food shortages are present; however, in cities where wild foods continue to be part of the routine cuisine, these foods can be substituted for less expensive foods with less cultural meaning and less satisfaction.It does not necessarily mean that wild foods are relatively more expensive, rather they are a component of a recipe that may be more expensive to prepare than boiling water for rice and pasta and adding tomato and fish.With this in mind, the discussion turns to the adequacy of food and wild food in cities in Cameroon.

Adequacy
According to De Schutter, adequacy "requires that foods satisfy dietary needs (factoring a person's age, living conditions, health, occupation, sex etc.), be safe for human consumption, free of adverse substances and culturally acceptable" ( [24], p. 4).From this list, food safety is a main concern for many urban residents.Many households surveyed in Yaoundé noted that "in the poissonneries the fish is not always fresh but the vendors do not shy away from selling it to the customers."The vendors complain about perishability and mention that the food they sell rots quickly in the rainy season due to dampness, and dries out in the dry season under the sun.Customers are aware of these issues and note particular markets to avoid certain products at different times of the year.Other households disregard the health warning for sustenance.Going back to the frozen chicken scandal example in the introduction, food consumers have to be highly aware of the foods they are buying and eating to avoid what is locally referred to as "running stomach," caused by contaminated foods.
In terms of food satisfying dietary needs and being culturally acceptable, there is an "informal rule" in the Cameroonian cities studied: the less money you have, the more imported rice you eat.Remarkably, a study of the urban plantain sector in 2004 or pre-global food crisis showed that "imported products such as rice or wheat are… generally more expensive than local products" ([104], p. 189).After the crisis consumer sovereignty has been "non-existent in markets where women have faced a "take it or leave it" choice of buying imported rice or nothing at all" [132].The new "preference" of urban Cameroonians post 2008 for "quick" and "easy" rice is rapidly changing diets.Now imported rice is a daily staple because it is available cheaply (Figure 8).The rice that is imported is the milled white rice, which is devoid of the husk and bran.This often results in a version of rice that is quick to cook, but is low in fiber and vitamins.Cheap rice shifts purchasing patterns of urban households away from traditional, local foods (such as cassava, cocoyam, plantain, local rice and wild vegetables), which are nutritionally more beneficial and Cameroon has a comparative advantage in producing.Older women surveyed are shocked by the frequency at which their younger counterparts prepare and eat rice.To these older women, rice was a special occasion dish, often being served for the Sunday meal or for holidays with chicken.
When asked: how many times do you prepare rice per week, most women stated that they serve rice three to four times, some even claiming they eat rice up to five times a week.The role of rice in the alimentation of households was most commonly stated as being "primordial" as "it allows me to make ends meet in difficult times".Other women used adjectives such as "important" and "profound."Almost all households surveyed stated that rice serves "a big place in the household menu, because it is not very expensive, it is accessible and easy to cook, it is the most consumed product in our household."The origin of the rice most commonly consumed is Thailand where the heartier Cameroonian rice is reserved for holidays.
The second "informal rule" is that cultural and culinary history dictates that rice is normally not an accompaniment to dishes made with HFZ wild foods.In Cameroon rice was grown in the grasslands, outside the forest zone and takes on a different culinary history.Most wild foods available in markets throughout the country originate from the forest zone.For example, leafy green vegetables are "mainstays in the diets of rural and urban households across most of Africa" more generally, and are especially important in Central Africa [133][134][135].Wild leafy vegetables may be the major source of micronutrients for the majority of resource-poor people throughout the region [12,71,135,136].Traditional leafy vegetables (in particular, Amaranthus spp., Corchorus spp., Solanum spp., Manihot esculenta and Gnetum spp.) on a per unit cost basis supply disproportionate shares of protein, minerals and vitamins [133].In particular, (Gnetum spp.) when cooked as a dish, is not only high in iron and zinc, it is also a rich source of protein and essential lipids.These greens are particularly important in the supply of iron and vitamin C, which may alleviate high levels of anemia in Central Africa exacerbated by high incidences of malaria.Initiatives are underway in East Africa to make African leafy vegetables (ALV) more accessible to the urban population [137,138].Lessons learned from this initiative can be useful to places where the environment and diet are welcoming of these foods.Ethnic group and regional ties do have a role to play in dish composition and accompaniments.Eru or okok (Gnetum spp.) is not served with rice; it goes with miondo, which is made from cassava/manioc, or fufu, which is also made from cassava.Fish mbongo goes with plantain.Njansang sauce with fish goes with plantain.In Cameroon, culture, ethnicity and region command what foods go with what.Agricultural products such as groundnuts and chicken go with rice but these dishes emerged from a different culinary history and one that is more similar to West Africa than Central Africa [123].Cameroonians enjoy this cultural diversity in their meals and this "informal rule" helps in ensuring dietary diversity.While the nutrition transition has been slower to emerge in Cameroon as compared to other developing countries, the evidence for a nutrition transition in Cameroon is mounting as food prices are affecting the adequacy of diets.

Discussion and Conclusions
Cameroonians enjoy dietary diversity and the ability to prepare foods from the many regions and ethnic groups that make up the country and fortunately, in urban areas, people come into contact with many of these flavors and culinary histories.However, access to the foods that ensure this diversity is a major barrier and daily obstacle and is driving the nutrition transition.When asked what does it mean to be food secure in Cameroon, most women mentioned affordability and said: "if you have enough money, you will be food secure" and "it means at least the average person can afford for (sic) food."Being food secure means "we can feed our families.But it is very difficult to have food all the time."One woman said: "I think it means having enough to eat at all times and if possible varieties.But most of the time we eat what we have, not what we want."Prices were mentioned in addition to income, "despite everything feeding ourselves remains a major problem, products are expensive and all the households cannot satisfy their hunger" and "life is very expensive in Yaoundé particularly for food; to eat well we are forced to spend too much."Most interestingly, one woman said: "the food basket of each household is becoming more and more meager because life is expensive in our country in general and in the city of Yaoundé in particular."When prompted to offer suggestions to fix this problem participants in the survey overwhelmingly and unanimously mentioned prices and access, and suggested "we need to learn to eat our own products and the Cameroonian state must watch and review the food prices and to act."Finally, one woman responded: "I will end by saying that food products in Yaoundé are expensive, very expensive.A family of four cannot afford to eat manioc at 500/FCFA (USD$ 1) in one day while it is cultivated here on place."A major theme that emerges from the responses of these women is that the food crisis has priced locally available and nutritious foods out of reach and this impacts the sustainability of nutritious diets in this Central African nation.
This article analyzed the ways that wild foods contribute to the food security of urban households in southern Cameroon.Regarding availability, the study found that at least 66 wild foods were named and sold in the food markets of Yaoundé, Buea and Limbe.The availability of these foods relies on seasons, weather, and access to the surrounding tropical forest.The availability of wild food and wild spices ensures the routine, traditional cuisine.As regards accessibility, the survey and interview data suggest that Cameroonians spend 50%-75% of income on food and that of that figure, 25% is spent on wild food.The data also found that more money is spent on food in the dry season and eating habits change between seasons.The study also found that many people continue to believe that the accessibility of wild foods is necessary for the preparation of routine meals.Additionally, the study found that the food price crisis has had a huge impact on the accessibility of wild foods and also local foods as these foods are increasingly (relatively) more expensive in the context of the government's subsidy scheme.Interestingly, the coping strategies adopted in households differ between Anglophone and Francophone cities.More people in Buea and Limbe do not have access to the kinds of foods they want to eat and in Yaoundé people reported that they do not have enough to eat and eat less frequently.Finally, with respect to adequacy, the data indicate that the less money households have, the more imported rice is eaten (three to four times a week); however, rice is not an accompaniment to dishes made by HFZ wild food.Consequently, high prices are changing diets, as urban residents are part of a global trend towards a nutrition transition.
Through organizing and analyzing the data in light of De Schutter's dimensions a new framework has been applied to understanding wild food, food security, and ultimately sustainability in Cameroon.As his approach is contested, De Schutter's framework is not the only way of knowing about wild foods and food security in this country.That being said, it is an instructive one.Through this lens many uniformities and similarities with respect to the challenges of wild food were identified with the notable exception of the different types of coping strategies that households adopt in the cities of research.Other approaches might yield different results, and further research in other cities on this topic in Cameroon and elsewhere in Africa is called for.
On his 2012 mission to Cameroon De Schutter concluded that the country had made little progress in eradicating poverty and hunger in the last ten years, despite the adoption of poverty reduction measures.He also found regional disparities to be particularly strong [25].In his view, the sustainability of food chains and food choices has been greatly impacted by the government's inattention to agriculture and food after the oil boom in the 1980s.This inattention was compounded by a series of structural adjustment programs in 1997 and the devaluation of the FCFA.In this environment, the 2007-2008 food crisis has had far reaching effects.Given his recommendations and my findings, it seems appropriate to call for more explicit language in the National Poverty Reduction Strategy Paper, Cameroon's Vision 2025, the Rural Sector Development Plan, and Cameroon's National Food Security Strategy regarding wild and traditional foods.As the government considers eliminating consumer subsidies introduced during the global crisis, Cameroonian consumers face the prospect of higher or more volatile food prices.The elimination of subsidies could force more urban dwellers to pursue coping strategies that push them away from relying on the wild traditional foods they would prefer to eat, and continue to facilitate a dietary transition away from a rich historic source of dietary adequacy.Alternatively, this eventuality could result in an unsustainable return to reliance on "foods from the forest".Regardless of the fallout from subsidy reforms, new and ongoing research needs to be carried out in urban areas on the accessibility of diet rich foods to better understand their contributions to food security, environmental sustainability, nutrition, and public health.
