The synergistic dilemma of upstream actors in the agro-ecological product supply chain restricts the transformation of ecological value, and traditional research focuses on the “production-supply” dichotomy, neglecting the driving role of the innovation service system. This study innovatively proposes a theoretical framework of “industry-supply-innovation tri-system synergy”, constructs a dynamic evolutionary game model with “free-riding” behavior, quantifies the effects of synergistic cost sharing coefficients (θ), benefit distribution ratios (γ), and policy regulation variables on the evolution of the main body’s strategy, and reveals the key laws through Matlab simulation. The results show that: (1) the participation of an innovation service system can significantly improve the speed of cooperation convergence; (2) the initial willingness to cooperate and the fairness of benefit distribution dominate the evolution path, and the probability of the system converging to “active cooperation” increases significantly when θ > 0.5; (3) the policy needs to be complemented with the market, and the government optimizes the distribution of the benefits of innovation services to improve the efficiency of the supply chain. The government can optimize the distribution of benefits from innovation services to promote the efficiency of the supply chain. Accordingly, we propose a “market-policy” dual-wheel control strategy to promote the deep integration of multiple supply chain actors with the innovation service system as a link. Full article

The fall armyworm (FAW), Spodoptera frugiperda, a major pest in maize production, was assessed for its temporal and spatial distribution in maize fields during both the dry and rainy seasons of 2021 and 2022 in two agroecological regions in Benin (zone 6 and 8). Zone 6 (AEZ 6) “called zone of terre de barre” (Southern and Central Benin) consisted of ferralitic soils, a Sudano-Guinean climate (two rainy seasons alternating with two dry seasons) with a rainfall ranging between 800 and 1400 mm of rainfall per year; while zone 8 (AEZ 8) called “fisheries region” (Southern Benin” is characterized by coastal gleysols and arenosols with a Sudano-Guinean climate and a rainfall of 900–1400 mm of rainfall per year. In this study, 30 and 50 maize plants were randomly sampled using a “W” pattern during the dry and rainy seasons, respectively. Larval density, larval infestation rates, and damage severity were monitored over time. Taylor’s power law and the mean crowding aggregation index were applied to evaluate the dispersion patterns of the larvae. The results indicate a higher larval infestation rate and larval density in AEZ 8 compared to AEZ 6 during the dry season. In the rainy season, while the percentage of damaged plants was higher in AZE 8, no significant differences in larval density between the two zones were observed. The dispersion analysis revealed moderate aggregation (aggregation index = 1.25) with a basic colony of 2.08 larvae, i.e., an average initial cluster of 2.08 larvae observed per plant, reflecting the aggregation oviposition behavior of FAW. This study provides valuable monitoring data on the FAW’s distribution, offering insights for further research on population dynamics and developing predictive models for integrated pest management strategies.

In this article, we focused on studying the current barriers to implementing innovations in order for the agricultural sector to become more sustainable. Through a systematic literature review (SLR), 73 scientific articles were obtained with a search equation in SCOPUS. Of these, 48 were analyzed because of the mention of an obstacle preventing the sector from implementing innovations towards sustainability. Information related to the publication year, abstract, authors, keywords, innovation, innovation type, relationship with Fourth Industrial Revolution (4IR), identified barrier, nature of the barrier (internal/external), agricultural subsector, country, and methodology of each article was identified, and with VantagePoint software, a technological surveillance technique was applied as a quantitative analysis of the information. The United States is the country with the most publications related to the subject. The most mentioned keywords were “Sustainable Agriculture”, “Agroecology”, “Climate Change”, “Innovation”, and “Organic Farming”. Additionally, a qualitative analysis showed 43 types of innovations, 16 of them related to technology. “Organic Agriculture” is the most mentioned innovation, followed by “Genetic Engineering” and “Precision Agriculture”. In addition, 51 barriers were identified, 28 external to farmers and 23 internal. “Lack of policies that promote that innovation Innovative Practices” is the most mentioned barrier, followed by “Epistemic Closure”, “Unfavorable Regulation”, Climate-Smart Agriculture, and “Unskilled Labor”. This article is intended not only to show trends in the barriers to innovation that prevents the achievement of sustainability that the agricultural sector needs, but also to serve as an input for the development of policies that provide solutions to these impediments. It was shown that 17 out of the 28 external barriers are related to topics that could be solved by formulating policies, laws, incentives, guidelines, and regulations. Full article

The intensive advances in robotics have deeply facilitated the accomplishment of tedious and repetitive tasks in our daily lives. If robots are now well established in the manufacturing industry, thanks to the knowledge of the environment, this is still not fully the case for outdoor applications such as in agriculture, as many parameters are varying (kind of vegetation, perception conditions, wheel–soil interaction, etc.) The use of robots in such a context is nevertheless important since the reduction of environmental impacts requires the use of alternative practices (such as agroecological production or organic production), which require highly accurate work and frequent operations. As a result, the design of robots for agroecology implies notably the availability of highly accurate autonomous navigation processes related to crop and adapting to their variability. This paper proposes several contributions to the problem of crop row tracking using a four-wheel-steering mobile robot, which straddles the crops. It uses a 2D LiDAR allowing the detection of crop rows in 3D thanks to the robot motion. This permits the definition of a reference trajectory that is followed using two different control approaches. The main targeted application is navigation in vineyard fields, to achieve several kinds of operation, such as monitoring, cropping, or accurate spraying. In the first part, a row detection strategy based on a 2D LiDAR inclined in front of the robot to match a predefined shape of the vineyard row in the robot framework is described. The successive detected regions of interest are aggregated along the local robot motion, through the system odometry. This permits the computation of a local trajectory to be followed by a robot. In a second part, a control architecture that allows the control of a four-wheel-steering mobile robot is proposed. Two different strategies are investigated, one is based on a backstepping approach, while the second considers independently the regulation of front and rear steering axle position. The results of these control laws are then compared in an extended simulation framework, using a 3D reconstruction of actual vineyards in different seasons. Full article

Accepting that nature and culture are intricately co-evolved has profound implications for the ethical, legal, philosophical and pragmatic dimensions of social and environmental policy. The way we think about nature affects how we understand and manage ecosystems. While the ideals of preserving wilderness and conserving ecosystems have motivated much conservation effort to date, achieving these ideals may not be feasible under Anthropocene conditions unless communities accept custodial responsibilities for landscapes and other species. This paper’s origins are in the author’s work with the Martuwarra Fitzroy River Council representing Indigenous traditional owners in Australia’s Kimberley region. These landscapes, shaped by 60,000 years of human occupation, interweave knowledge, laws and governance regimes, and material and spiritual connections with country. This interweaving offers insights into options for dealing with humanity’s complex sustainability challenges. The paper also draws on the literature about cultural landscapes, ecological design, agroecology and permaculture to explore options for applying ecological design as a planning and problem-solving framework. The paper concludes that design-based approaches offer significant opportunities for using ecological science to integrate conservation and production in agricultural landscapes in ways that can meet human needs while also conserving biodiversity under climate change.

In the transition from linear production systems, unsustainable from the point of view of resources, to a model that finds strength in environmental, social and economic sustainability, the circular economy paradigm is the foundation that facilitates the planetary agro-ecological transition. The European Union has taken a number of steps (including the Circular Economy Package of Directives) shaping circularity as a wide-ranging driver measure involving many sectors. The paper intends to provide a regulatory framework on the current general situation regarding circularity in European Union, in order to extrapolate and give evidence to the aspects that intersect the agri-food sector. This is not only because they are poorly addressed in the literature, but also because there is a lack of regulatory instruments on the circular economy specifically addressing this area of interest. For this purpose, the analysis focuses on waste and residue/scrap management issues, recognized by law as by-products and end-of-waste status, as they are covered by circular economy legislation and as they can be applied to the agri-food sector. The latter allow the implementation of circularity strategies in the agri-food sector and, given the numerousness of production chains and the peculiarities of each of them, various regeneration and/or reuse processes of specific resources may be depicted. The intent is to provide useful knowledge on how to implement sustainable waste management, also proposing a concrete case on a by-product of olive oil processing, through which it is possible to highlight how the correct application of regulations favors the adoption of circular economic and management models in the firms involved, as well as informing the relevant economic operators on the possible profiles of legal liability that may arise from insufficient knowledge. Furthermore, this paper delves into the European Green Deal’s Strategy as it enriches the circular economy paradigm with new facets. NextGenerationEU and the National Recovery and Resilience Plan financially support this strategy in the aftermath of the socioeconomic crisis from COVID-19 in the EU Member States. This is in order to achieve the objective of achieving the agro-ecological transition. Full article

The COVID-19 pandemic showed an impact mainly on the health of people and the economy of households. The levels of food security in the world’s households, especially in Mexico, have decreased. When people do not have food security, their health is compromised and they have financial problems; on the other hand, environmental deterioration has a link with food security. The purpose of this review is to analysis of the current situation in Mexico of food security, environmental health and economy, the main lessons learned in these areas and their proposals integrating public policies. A review was carried out in the main databases (MEDLINE, Embase, CINAHL Plus, Web of Science, CAB Abstracts y PAIS Index) with the following keywords and according to the MeSH terms: Food security, food insecurity, environmental health, public policies, environmental, production, integrating the word COVID-19 in English and Spanish. Only 44.5% of Mexican households presented food security. For food insecurity, 22.6% had moderate and severe food insecurity, while 32.9% had mild insecurity. Food insecurity and the health impacts of environmental origin (waste management during the coronavirus pandemic, water contaminated by bacteria, viruses, and toxins; air pollution) generates impacts on economic activity by not offering food that meets health regulations. Without the application of cost-effective measures and interventions for the prevention and control of patients with obesity, the direct costs for 2023 will amount to 9 million dollars, which worsens the household economy. Despite having laws and policies on the right to food, a healthy environment (water), and opportunities for economic growth, these human rights are not fulfilled. The conclusion is that it is necessary to use a health and agroecological model to promote public policies (health, environment, and economy) that aims to prevent the discussed issues, with multidisciplinary and intersectoral interventions (government, academia, researchers, civil society organizations, industry, and population). This upholds the human right that all people should enjoy an adequate, healthy environment and have access to high-quality food. Full article

Sustainable agricultural development depends on female and male smallholders being effective farmers. This includes the ability to access or control resources and make the best decisions possible agro-ecologically, economically, and socially. Traditionally, gendered studies on innovation practice focus on female- versus male-headed households. In this paper, we focus on married women in acknowledged male-headed households and women heading their own households to examine how marital status influences women’s capacity to innovate in their rural livelihoods. Using data from eight community case studies in Ethiopia, we used variable-oriented and contextualized case-oriented analysis to understand factors which promote or constrain women’s innovative capacities. We use Kabeer’s Resources–Agency–Achievements framework to structure our findings. Single women are more likely to own land and experience control over their production decisions and expenditures than married women, but engage in considerable struggle to obtain resources that should be theirs according to the law. Even when land is secured, customary norms often hamper women’s effective use of land and their ability to innovate. Still, some single women do succeed. Married women can innovate successfully provided they are in a collaborative relationship with their husbands. Finally, we find that gender-based violence limits women’s achievements. The article concludes with recommendations. Full article

This paper offers an approach to Yucatecan social reality in terms of entrepreneurship and the process of creating companies dedicated to the production and/or commercialization of agroecological products, considering its contribution to sustainable rural development. The key actors’ perspective towards the existence of policies that favor land sustainability, assist in the development of rural areas and their population, and support these business initiatives is also presented. Likewise, it illustrates the small entrepreneurs’ standpoint on the role of public institutions in promoting wealth generation and sustainable development in lower growth areas, such as the state of Yucatan, in Mexico. A qualitative methodology was used for this research, based on in-depth interviews with a group of businessmen and -women from the region. The main results give a pessimistic view of institutional concern regarding both production and consumption of agroecological products and, therefore, the promotion of these enterprises for the socioeconomic development of Yucatan. From these findings, we detect: (a) A policy of scarce support for this type of production, due to political priorities; (b) inadequate management that prevents the consolidation of certain structures needed to support agroecological enterprises; (c) a lack of confidence in the Yucatecan government, which does not promote or support a social network of collaboration between agroecological producers and marketers; (d) a difficulty in undertaking agroecological enterprises because of social and cultural norms and poor environmental awareness among the population; (e) significant training deficiencies among entrepreneurs in agroecological agriculture; (f) absence of adequate distribution channels for agroecological products; and (g) excessive bureaucratic obstacles through laws that hinder entrepreneurial processes.

The profitability of the French agricultural sector has fallen over the last two decades, leading to the suggestion of a “rupture in technical progress”. Additionally, the intellectual property regime in force has contributed to the erosion of the cultivated biodiversity, limiting plant resiliency to climate change and other hazards. In the face of these challenges, agroecological farming practices are a viable alternative. This paper investigates the positive and negative aspects associated with the development of alternative seed procurement networks in France. The findings indicate that peasant seed networks can effectively contribute to overcoming many of the structural blockages with which French agriculture is confronted, but that yield concerns; higher information and supervisory costs, as well as the unfavourable legislative context, constitute key challenges to their development. However, these could be partially or totally eliminated if adequate policies are implemented. In this regard, the recommendations are to: (i) strengthen the dialogue with farmers in the shaping of policies related to the use of plant genetic resources; (ii) abrogate the “obligatory voluntary contribution” on farm-saved seeds; (iii) diversify the collection of Centres for Biological Resources, increase their number, and democratize their access; (iv) harmonize the French and European regime on intellectual property; and (v) encourage participatory research.

The popularity of agroecology has grown over the last few years as an alternative paradigm for food systems. This public attention has meant agroecology is increasingly becoming institutionalised and integrated into food policy frameworks. While there is a significant body of literature discussing the origins and worldviews intrinsic to agroecology, hardly any academic publications focusing on analysing policies claiming to have an agroecological focus exist. This first policy study of its kind contributes to the scarce agroecological policy literature by interrogating what we argue is a ‘translation’ process, which starts with the vision of agroecology and analyses how the concept changes once it has been operationalised into a policy document or law. Evidence from two European agricultural policy contexts, namely France and the United Kingdom, is presented. The methodology followed focused on the analysis of the context, problem construction, conceptualisation of agroecology, operational principles, and policy instruments included in the policy documents. Three main themes emerged from the case studies: differences in framing agroecology in the public policy arena; common dependencies to existing configurations influencing translations of agroecology in public policies; and the need for democratic discussion on the hybridisation of agroecology itself, as well as on implied, but often veiled, political choices. This paper concludes that a selective and relational hybridisation of agroecology is emerging during its ‘translation’ into public policies. Full article
