Adaptation to Climate Change in Panchase Mountain Ecological Regions of Nepal

Rural mountain communities in developing countries are considered particularly vulnerable to environmental change, including climate change. Forests and agriculture provide numerous ecosystem goods and services (EGS) to local communities and can help people adapt to the impacts of climate change. There is however poor documentation on the role of EGS in people’s livelihood and adaptation practices. This study in the rural Panchase Mountain Ecological Region of Nepal identifies practices being used to adapt to a changing environment through key informant interviews and focus group discussions. At the household level, livelihood diversification, changes in cropping patterns and farming practices, use of multipurpose plant species and income-generation activities were identified as adaptation strategies. Among major strategies at the community level were community forestry-based climate adaptation plans of action for forest and water resource management. Landscape-level adaptation strategies were large-scale collaborative projects and programs, such as Ecosystem-based Adaptation and Chitwan Annapurna Landscape conservation; which had implications at both the local and landscape-level. A proper blending and integration of adaptation strategies from individual households through to the community and to the landscape level is needed for implementing effective adaptation in the region.


Introduction
Rural people, especially in developing parts of the world, are more vulnerable to risks posed by ongoing environmental challenges, including climate change [1][2][3][4].The vulnerability of rural areas within South Asian countries is generally considered through the loss of crops, shelter, community infrastructure, and socio-economic activities [5,6].This is primarily because people depend on water, food systems, forest products, and other natural resources for their livelihoods.These resources, however, are more vulnerable to the impacts of climate change [7].As a result, people tend to have limited adaptive capacity to deal with these impacts [3].The concept of adaptive capacity can be used differently in varying contexts.In the case of adaptation to climate change, we follow the definition by the Intergovernmental Panel on Climate Change (IPCC).It defines adaptive capacity as "the ability of systems, institutions, humans and other organisms to adjust to potential damage, to take advantage of opportunities, or to respond to consequences" [8].The concept of adaptive capacity is closely related to the vulnerability of socio-ecological systems of communities.Therefore, vulnerability is generally understood as being composed of the exposure and sensitivity of a system to external stresses and the adaptive capacity of the system to adapt to such stresses [9][10][11][12].Moreover, deep-rooted unequal social structures and chronic poverty also contribute to the vulnerability of rural communities facing differential climate change impacts [13,14].
Most rural communities in developing nations are endowed with forests, agro-ecosystems, and water resources and the large array of ecosystem goods and services (EGS) they provide.According to the World Bank, 1.6 billion people depend on the EGS derived from forests for their livelihoods [15].EGS are increasingly recognized for their importance in fostering the adaptive capacity of local communities in response of environmental stressors, such as those posed by climate change, in tandem with socio-economic stresses [16][17][18][19][20].The practical application of EGS to increase adaptive capacity and human well-being at local level is still debated [21][22][23].However, many studies have acknowledged the potential of EGS, especially those providing provisioning and regulating services, to increase adaptive capacity and contribute to human well-being and people's livelihood [24][25][26][27].
In Nepal, EGS have a crucial role in supporting the livelihoods of people.Most rural communities in the region depend on forest and farm-based EGS such as fodder, fuel wood, grasses, water, and food for their livelihoods [28][29][30][31].Sixty percent of economically active people are engaged in agriculture as a primary source of livelihood [32].Forests support agricultural land by providing protection from erosion and landslides, as well as different products such as water resources for irrigation, forage for livestock, and litter for nutrients and organic matter.This makes up the typical relationship between forest, farm, and livestock as an agroforestry practice, especially in the mid-hill region [33].Traditional energy sources such as fuel wood from forests and agricultural residues and livestock dung still constitute 87% of the country's total energy supply [34].Together, forest and agriculture contribute more than one-third of national gross domestic product (GDP) [35][36][37].This economic contribution suggests the country is reliant on EGS, especially those derived from forests and agro-ecosystems.Community-based forest management, especially in the mid-hill regions, have contributed to an increase in EGS [38].Reforestation, restoration of degraded forests, and reduced deforestation and degradation within these regions are responsible for the increase in EGS [38].In contrast to the hilly region, several anthropogenic disturbances such as grazing, encroachment, deforestation, illegal logging, unsustainable harvesting of non-timber forest products, and forest fire in the lowlands of the southern plain pose many challenges to the sustainable management and use of forest-based EGS [39][40][41][42].
In many parts of the world, environmental stressors such as drought, landslides, floods in conjunction with deforestation, and forest degradation, have already had a negative impact on EGS.For example, Nepal Himalaya has experienced a 1.5 • C increase in temperature between 1982 and 2006, at an average rate of 0.06 • C per year [43].This is well above the global average increase in temperature at 0.02 • C per year observed between 1975 and 2005 [44].The rapid change in temperature has had implications for food production, water resources, natural hazard prevention, and overall ecosystem function [43,45,46].Consequently, the Climate Change Risk Atlas 2010 ranks Nepal fourth on the list of countries most vulnerable to climate change [47].
Despite being rich in EGS, the people in most rural areas of Nepal are comparatively more vulnerable to climatic risks than in other countries suggesting that a "paradox of plenty" may exist [48].The reliance of rural communities in Nepal on EGS that are vulnerable to climate variability and change suggests that adaptation to both observed and future changes in climate is necessary [1,30].Adaptation measures operate at different societal and spatial scales [49].Adaptation measures also require a holistic and integrated approach to implementing community-managed resource-based activities to enhance local adaptive capacity [50].Activities related to building infrastructure, institutional and communication networks, supported by government initiatives and international organizations are important for fostering adaptive capacity [50].The effectiveness of these strategies needs to be evaluated based on different criteria that are relevant at different levels [49].In this context, managing EGS from both forest-and agro-ecosystems could help people meet their basic needs and tackle problems posed by different drivers, including climate change.Some work has been done to document adaptation practices in other countries such as Bangladesh [51][52][53] and Vietnam [54].
However, in Nepal, few studies have systematically documented adaptation measures being used to combat the impact of climate change.A knowledge gap also exists in the potential of locally available EGS to support climate adaptation initiatives from households through to communities and across landscapes.Adaptation initiatives by individual households reflects household-level adaptation [4], whereas community-level adaptation refers to a community-led process and practices designed to empower people to plan and cope with the impacts of climate change [55].Landscape-level adaptation aims at a broader landscape comprising a mosaic of agricultural land and other natural habitat [56].This study fills the knowledge gap by documenting adaptation practices from the household to landscape level through a case study from the Panchase Mountain Ecological Region (PMER) of western Nepal.The PMER is rich in natural and socio-cultural resources but is regarded as vulnerable to climate change, which is expected to have negative impacts on forests, water resources, and agriculture diversity [57].A recent study showed annual average maximum and minimum temperature increases at the rate of 0.043 and 0.023 • C, respectively; precipitation is decreasing by 11.2 mm per annum and becoming more erratic in pattern [58].By documenting adaptation practices, the study seeks to understand how they are being implemented and to provide directions for further adaptation planning.

Study Area
The study was carried out in the Panchase Mountain Ecological Region (PMER) (latitude: 28 • 8 36 N to 28 • 18 17 N, longitude: 83 • 43 69 E to 83 • 59 5 E) of western Nepal (Figure 1).The PMER represents the mountain ecosystem linking the lowlands and the high Himalayas of the Annapurna range of Himalaya.Five villages, i.e., Bhadaure Tamagi, Chapakot, Pumdighumdi, Kaskikot, and Dhikurpokhari, were used for the study purpose within this PMER.Out of five villages, Bhadaure Tamagi is the one principally used for data collection.Bhadaure Tamagi typically represents both upstream and downstream regions with distinct land use and farming practices.At the same time, it covers the top of the landscape to the valley bottom downstream.The District Forest Office and Panchase Protected Forest Program (PPFP) also suggested that we choose this site primarily for field observation.The PMER is rich in forest and biodiversity resources and provides several EGS to the local communities to sustain their livelihoods [59].More than 14,807 households in the area depend on EGS for their livelihoods.A diversity of goods and services available from the region's forests might be due to the variation in forest and tree species, which occurs across an ecocline of 815 to 2517 meters above sea level [57].
The upstream region (above 1400 m) of the study area is dominated by a mix of forest and farmland.The uppermost portion of this region is located within the Panchase protected forest (PPF).The PPF is being managed mainly for conservation of biodiversity, cultural, and religious values, ecosystem services, and medicinal plants.It is also the source of water for both the upstream and downstream regions.Outside the PPF, this region is comprised of farmland and community-managed forest area, which provides both farm-and forest-based goods and services for the livelihoods of local communities.
The downstream region (800-1400 m) for this study is characteristic of a production landscape comprising food and agricultural crops.Downstream (~800 m) regions encompass flat land in valley bottoms, which is important primarily for production of rice (Oryza spp.), maize (Zea mays), and wheat (Triticum spp.).The fringe area of protected forests and community forests provide basic forest products for communities.

Methodological Approach
In this study, various participatory rural appraisal (PRA) tools were used in data collection [60][61][62][63][64].The methodological framework is illustrated in Figure 2. Well-facilitated PRAs offer a quick and affordable method for gaining insightful and accurate data [5,65,66].However, the identification of key informants is quite challenging.Even if the right person is chosen, informants might be biased and may not represent, or even understand, views held by the majority in their community [67].Therefore, it is important to invest time and effort in identifying the appropriate participants for the process.Local community members are good candidates for PRA as they are typically more familiar of the local context than outside experts [68] and are keen to engage in the research process.However, the responses from these participants depend upon how they have interacted with the environment [65,69].
First, interviewees for KII were selected based on their knowledge of the local adaptation practices.For example, forest users, current and former executive committee members of community forest user groups (CFUGs); school teachers; members of women's groups, disaster risk reduction (DRR) groups, farmer groups, and indigenous, ethnic, and marginalized groups; and elderly people were identified as key informants [65].Altogether, 37 in-depth interviews were conducted.Each interview was semi-structured in nature and interviews lasted from 1-1.5 h.The "concept of saturation" was used to determine the number of interviewees [62,76].This helped keep the sample size small [62,77] while ensuring an optimum level of information as far as possible.
After a series of individual interviews, we organized separate focus group discussions (FGDs) among the villagers and forest managers.First, we appointed a field assistant from the village as a contact point in the field.The field assistant helped identify participants for FGD as per our requirements, contact them before the discussion and then organize FGDs in each locality.The field assistant was from the local community and at the same time had both theoretical and practical knowledge on organizing FGDs, data collection, and group facilitation.These multiple qualifications helped the field assistant identify and organize the FGDs.We held three focus group discussions among villagers and one among forest managers.Each FGD had five participants.As in the KII, participants in the FGD were forest users, executive members of CFUGs, farmers, indigenous and elderly people, and marginalized members of the community.Forest officers, rangers, the manager of PPF, and the chairperson of the PPF Council were involved in FGD and expert opinions at the district headquarters.Some selected participants declined to join the discussion because of conflicting commitments.However, each FGD had at least five members through the participation of alternative participants.The chairpersons of the forest user group and farmers' group were also consulted during the selection of participants for FGDs.As the main purpose of the study was to document the major adaptation practices in the study landscape, we chose participants based on who could contribute more in the discussion and help generate data.Half of the participants were women.We did not organize separate FGDs for male and female participants; the study aimed primarily to identify adaptation measures at the household, community and landscape levels rather than document gender-based disaggregated adaptation practices.
To ensure effective engagement of participants in the discussion (quality) rather than to involve as many participants as possible (quantity) within each FGD, we played the role of facilitator and moderated discussion among participants instead of asking questions repeatedly.As in other PRA tools, FGD can also generate large amounts of data in a relatively short period.Yet, rich data can only be generated if individuals in the group are prepared to engage fully in the process [68].Public spaces and CF buildings were used for the meeting venue in the community-level FGDs, as well as discussions with participants, whereas the District Forest Office's meeting hall was used for FGDs with forest managers.The main points from the discussion were noted in a diary.The entire discussion was audio recorded and transcribed later for data analysis.
A transect walk from the lowlands to the peak of the Panchase was conducted to verify information collected through the interviews and FGDs.Published and unpublished reports of relevant government entities and non-governmental organizations (NGOs) were reviewed as secondary sources.These included operational plans of community forests and PPF and community forest-based Climate Adaptation Plans of Action (CAPA).Data were qualitative in nature and analysed in Nvivo [78].All the interviews were transcribed and translated from Nepali into English prior to analysis using Nvivo.

Results and Discussion
All the adaptation initiatives in the study landscape are classified into three broad categories: household, community and landscape-level.This was considered the most suitable approach for this study.We acknowledge other studies have recommended different categories such as local, national, and international-level adaptation [49,79]; farm, landscape, and national-level adaptation [80]; and tropical to polar ecosystem-level adaptation [81].

Household-Level Adaptation Practices
Major household-level adaptation practices applied were changing resource-use patterns and gradually shifting livelihoods from existing practices to newer ones more suitable for a changing environment.Changing practices included, for instance, use of biogas instead of firewood, and switching from traditional food crops to multipurpose cash crops and vegetables, income generation, and livelihood diversifications (see Table 1 for details).Household-level adaptation measures related to the use of available EGS derived from forest and agro-ecosystems were some of the most widely applied in the study landscape.This corroborates the findings of earlier studies [14,30,35,82] in Nepal and has also been observed around the world [9,52,53,80,81,83].For instance, Bhattarai et al. [35] found that, at the household level, cash cropping-especially tomato and adoption of high-yielding improved rice crops-was an adaptation strategy to cope with the environmental impacts on traditional cereal crops.Similar adaptation measures were also observed in Dolakha district, in which kitchen wastewater and rainwater harvesting were used as a household-level adaptation measure [30].
In hazard-prone coastal areas of Bangladesh, important adaptation strategies have also occurred at the household-level such as adoption of new crop varieties, change in planting times, household gardening, rain water harvesting, and tree planting [51,52].The levels of household adaption identified are consistent with Lopez et al. [80], who defined three measures of household-level adaptation.First, cultivation of a larger number of species and farm diversification; second, introduction of, or increased cultivation of, better-adapted crops and varieties of livestock animals and breeds; and third, integration of trees and shrubs into production systems.• Improved management of livestock's dung and urine in which urine is collected and transferred to the collection spot • A clean cattle shed with urine collected for organic vegetable farming, which otherwise would have disappeared or not been used at all Use of farmland in cash crops, vegetables and fruit production • Conversion of farmland (including abandoned farmland) to grow cash crops such as vegetables, fruits, coffee and broom grasses in the wake of reduced productivity of regular cereal crops

Fodder and multi-purpose tree plantation, home garden
• Identification of multipurpose plantations, mainly fodder and fruits tree species, to meet the local requirement of fodder and fruits • Plantation and management of tree species on both private and public land.
• Reduced pressure of fodder on forest and strengthened forest conservation • Easy access to fodder resources without spending much time and energy • Enhanced livestock products, and thereby varieties of agro-goods and services • Promotion of agroforestry practices.
Various studies have found the limited practice of adaptation options by smallholder farmers due to a limited capacity to implement them [4,52,84].Some identified constraints include lack of money, lack of access to adequate information, inadequate technical knowledge and awareness, and unclear property rights to promote household-level adaptation practices [4,52,84].Individual smallholders should therefore be supported through various adaptation measures such as agroforestry, organic farming, sustainable farm management, low-cost technology, crop diversification, and access to finance and information [82,85].The use of agroforestry practices in particular is a low-cost technology alternative that can increase productivity, generate income, and diversify livelihood opportunities.From an ecological perspective, it will also support ecosystem restoration and soil conservation and reduce land degradation and associated environmental risks.
Household-level adaptation measures were found to be carried out by either individual family members or all family members.Most adaptation practices were autonomous in nature; the household adopts measures on its own in the absence of specific policy initiatives that promote adaptive behavior [86].Changing species composition and cropping patterns are examples of autonomous adaptation.On the other hand, external agencies may either initiate or support adaptation measures such as promoting vegetable farming in polyhouses through an Ecosystem-based Adaptation (EbA) project.In such cases, adaptation could be understood as "planned" adaptation [81,86].Similarly, our findings show that if external institutions supported individual autonomous adaptation measures, these measures were more likely to become more effective.The practice of homestay in the study area, supported by EbA projects, was found effective for diversifying livelihoods by generating income not reliant on climate sensitive EGS.Similarly, use of alternative energy such as biogas was also found effective.It exerted less pressure on forests, reduced workloads required to collect firewood, and reduced health hazards by reducing exposure to smoke resulting from traditional cooking stoves.Our study highlights that with the support from government and other external agencies effective adaptation measures at the household level can enhance the adaptive capacity of individual households within communities.

Community-Level Adaptation Practices
We documented some community-level adaptation programs in the study landscape (Table 2).These adaptation practices were found to be initiated by various community-based organizations such as CFUGs, disaster risk reduction groups, farmers' cooperatives, and women's groups in the village.For example, two community forests have an innovative CAPA in water resource management.Community-based restoration and conservation of water ponds were other examples of community-level adaptation to water shortage.Likewise, the role of CFUGs in managing forest fires was also found effective; as a result, forest fire is not a major problem in the region.Further, awareness raising and capacity building of community members, demonstration and conservation plots of threatened plant species were also identified as adaptation measures to cope with the impact of climate change.Due to community engagement in ecosystem management especially via the community forest program, these demonstration and conservation plots also significantly contributed to community-based forest landscape restoration practices.Unlike individual household practices, community-level adaptation initiatives, also known as community-based adaptation (CBA), were based on collective action.The community works for the common benefit to maintain or improve living standards in the face of climate change [87].CBA should reflect communities' priorities, needs, knowledge, and capacities; it empowers people to plan for and cope with impacts of climate change [45,55].Even small differences in the pattern of society's fabric for collective action can have profound implications in the ability to cope with environmental shocks, including climate change [88].
Although not designed for adaptation to the impacts of climate change, community forest (CF) management has significantly helped enhance the adaptive capacity of local communities to climate change.Adaptive capacity of local communities has increased due to the formation of natural capital, livelihood (human and social) capital, strong grassroots institutions, and the capacity to manage and use forests within the community [38].Moreover, CF has also contributed to community-based forest landscape restoration (CBFLR) [89], converting a degraded landscape into one containing rich and diverse areas of forest over the last 30 years [89,90].Similarly, due to increased awareness and engagement on the part of CFUGs, forest fire is no longer a major problem in the landscape.As a result, CF and CBFLR have played a crucial role in biodiversity conservation, ecosystem management, integrated water resource management, improved water quality, and the building of links between forest and agriculture.Ultimately, they have improved the overall livelihoods of people dependent on forest resources [38,62,89].However, even within the same community, vulnerability and adaptive capacity differ from individual to individual and from group to group [91].Poor and marginalized sections of the communities should be better included in decision making and benefit-sharing mechanisms to increase their adaptive capacity, while directing more benefits toward privileged groups needs to be avoided [92,93].
Following the legacy of successful management of community forestry (CF) in Nepal, CF-based Climate Adaptation Plans of Action (CAPA) have also been initiated in the region.The impact of climatic and environmental stressors has been primarily observed on the availability of water for both drinking and irrigation in the studied landscape.CAPA was designed to protect water sources in the forest and water supply to the village.Other areas incorporated into the CAPA include the conservation and recharge of ponds and managing forest fires in the dry season.A supply of drinking water from the forest, as envisioned in a CF-based CAPA, has helped meet community water requirements in the upstream region but not in the downstream region.This lack of success might be due to pressures from a large population and increased demand of water in downstream areas compared to the upstream region.The growing trend of people migrating from the upstream to downstream regions has put more pressure on natural resources, including forest and water resources downstream [94].Contrary to the effective community-based fire management practices identified, water management does not appear to be effective at the community level, requiring more robust local institutional and governance mechanisms to support the initiative.Similarly, a disaster risk reduction (DRR) group in the downstream region lacked robust institutional and support mechanisms from within and outside the community.Yet protection and maintenance of community-level conservation ponds in different parts of the region have helped recharge groundwater by collecting excess water in the rainy season and reducing water-induced hazards such as landslides.
The role of community-based institutions in enhancing adaptive capacity and overall effectiveness of adaptation practices has also been acknowledged in other places, especially in disaster risk reduction and climate adaptation [76,90].For instance, Ahmad et al. [95] prepared the first community-based flood management manuals in South Asia (Bangladesh, India, Nepal) in responses to floods and categorised them into pre-flood responses and responses during floods with a series of steps within each response.As a result, the concept of the community-based flood management committee [5,95] and community-based adaptation committees' (CBACs) [50] has evolved to carry out adaptation activities in the community.In Bangladesh, the local community-level Village Disaster Management Committee (VDMC) that collaborates with local government and other organizations has introduced some innovative practices for climate change adaptation [96].However, maintaining effective coordination among different government and civil society organizations, NGOs, and local communities in the field is still a challenge [96].In general, decisions for community-level adaptation are based on the autonomous and collective action of community.Any input and support from external organizations could influence the community's decision, and thus its autonomy.Yet, as these practices are based on local and indigenous knowledge, the chance of adaptation success remains high even without input and support from external organizations [97].

Landscape-Level Adaptation Initiatives
Given the considerable socio-ecological importance of Panchase landscapes, various landscape-level conservation and adaptation initiatives have been applied to contemporary environmental challenges.Major initiatives include the Government of Nepal (GoN)-initiated Panchase Protected Forest Program (PPFP), the UNDP-led Ecosystem-based Adaptation-EbA (piloting phase), the IUCN-coordinated Ecosystems Protecting Infrastructure and Communities (EPIC), and the WWF-led Chitwan Annapurna Landscape (CHAL) program in the region.The landscape-level initiatives in the region are another form of adaptation to the impacts of climate change [98,99].The major landscape-level adaptation initiatives in the field are listed in Table 3.
We found that all adaptation initiatives that operate at the landscape level in the region cross beyond traditional political and administrative boundaries.These initiatives were also found to cover a variety of sectors, including protected forests, community forests, ecosystem protection and management, agroforestry, infrastructure protection, and watershed/river basin management.They involved various governmental and non-governmental stakeholders such as IUCN, UNDP, FAO, local NGOs, and communities.The landscape-level initiatives were primarily designed for biodiversity conservation, landscape and scenic beauty, and to provide broader benefits and improve human well-being to both upland and lowland regions through a range of EGS [99].For example, PPFP was focused on conservation of the biodiversity-rich Panchase forest.The EbA project encouraged both individual households and communities to use EGS to help them adapt to changes throughout the project (ended in 2016).
The major thrust of landscape-level adaptation initiatives was to strengthen the capacity of nature to adapt to the changing climate and then help improve the adaptive capacity of human beings through a variety of EGS [100].The EbA project has provided a solid framework for planning and implementing integrated adaptation [101].EbA holds much promise in countries like Nepal that has several landscapes like the PMER with varieties of EGS; at the landscape level, EbA can also help accommodate diverse social, environmental and economic needs during planning and implementation of adaptation activities [101].However, integrating all those diverse needs and crossing administrative boundaries in climate adaptation activities is still a great challenge that makes decision making complex.Further, much of the development programs and activities take a sectoral approach such as forestry, agriculture, infrastructure and so on.Therefore, breaking the sectoral silos while adopting landscape-level integrated adaptation initiatives should be encouraged for effective landscape-level adaptation in the PMER.• Awareness building and stakeholder engagement in exploring the ways to use abandoned and underused land.
• Pilots explore the best agroforestry options for use of abandoned agricultural/underused land as effective adaptation measures • A national action plan is developed for scaling up of using underused/abandoned agricultural land

Integrated Adaptation Approaches
The assessment of adaptation practices has provided insights into a range of approaches that are used at household-, community-(CBA) and landscape-levels (EbA) within the PMER.Each approach has its specific focus and emphasis.For instance, household-level adaptation and CBA aim to empower individual households and local communities by helping increase adaptive capacity and reducing vulnerability [102].Conversely, EbA attempts to harness the management and use of ecosystems through a suite of EGS in the face of climate change [99].However, it would be erroneous to distinguish between EbA and CBA based on their priority for either ecosystem-or people-centered adaptation [103].Integration of both approaches provides unique opportunities to embrace activities that are both community-and ecosystem-focused such as EGS in people-centered adaptation [103,104].Moreover, integrated adaptation approaches should fully appreciate ecological and social complexity.For instance, CBA projects may not incorporate ecological complexity, whereas EbA projects might not appreciate social complexity.For example, an EbA project could fail to understand and consider the unique needs of marginalized social groups and how to engage them meaningfully to achieve intended adaptation benefits [103].
Integration of adaptation practices at different scales can be carried out in several ways.First, adaptation at an individual household and community-level should support overall landscape level adaptation and vice versa.For instance, agroforestry practices at the household-level and plantation management in communal lands can support overall landscape-level ecosystem restoration and enhance EGS.The contributions of an individual's adaptation to climate change in landscape-level adaptation have also been reported in Dutch forests [105].Second, most adaptation planning and implementation take a sectoral approach such as agriculture, forest, water and energy.Though these measures have brought some positive impacts in their respective sectors, an integrated approach at the landscape-level is needed to cross-traditional administrative boundaries for sustainable and effective adaptation in the field [103].An integrated, coordinated, and targeted strategy is needed for climate change adaptation.In other words, even if integrated adaptation policies have specific strategies in each sector, sector-wide efforts at the landscape or watershed level should increase synergy among adaptation strategies in different sectors and reduce the negative trade-off as far as possible.For example, a larger number of adaptation activities in an agriculture sector were identified; however, to sustain agricultural adaptations, proper management and adaptation of other sectors such as forest conservation, irrigation, and watershed management are required to prevent loss or damage to agricultural-based activities due to landslides, floods, and changes in water availability.
Due to the scale, urgency, complexity, and uncertainty of how climate change may impact ecosystems and rural livelihoods, integrating adaptation approaches and collaborative partnerships are becoming more important than ever [103].Given the considerable success of community forestry to arrest land degradation and increase forest landscape restoration (FLR) [89], broader-scale community-initiated integrated adaptation approaches could work within the region.Community forestry could be an entry point for implementing integrated adaptation.Similarly, the community forestry-based climate change adaptation (CF-CCA) framework could be a viable option to spearhead integrated adaptation efforts [106].To ensure household and community-level adaptation are encompassed into a broader landscape-level framework, it is best that "community-led" or "community-controlled" adaptation in EbA be practiced to foster integrated adaptation across scale [103].Existing networks of local community forest groups could facilitate this process by lowering transaction costs and scaling-up of lessons learned in applying community-lead processes across large and more diverse areas [103].

Conclusions
Despite rural communities residing in an EGS-rich landscape in Nepal, they are still considered vulnerable to the impacts of climate change in part due to their perceived lack of adaptive capacity.In this study, we found that at the household-level, livelihood diversification, changes in cropping patterns and farming practices, use of multipurpose plant species, and income-generation activities are key adaptation strategies being autonomously employed.At the community level, community forestry-based management and water resource management were found to foster adaptive capacity.At the landscape level, adaptation strategies fostered by collaborative projects and programs such as EbA and CHAL conservation were found to link some adaptation strategies from local to landscape level.While efforts to implement adaptation are occurring through ecosystem-based adaptation, a strategic integration of adaptation strategies and practices from the household through the community to the landscape-level is required.The integrated approach of adaptation should go beyond the sectoral and administrative boundaries to ensure proper use of EGS within the landscape.Given the considerable success of participatory approaches in forest management, community-led initiatives such as a community forest-based integrated adaptation approach might be a viable option and entry point to promote adaptation practices in the region.
