Rural organizations and adaptation to climate change and variability in rural Kenya

Numerous studies have shown that collective action affects the type and efficiency of short- and long-term adaptation to climate change. This empirical study contributes to the body of the literature on collective action and adaptive capacity by demonstrating how organizations frame responses to climate variability and change in rural Kenya by promoting local rural institutions. By analyzing interviews, role-playing games, and household surveys, we ask how local rural organizations shape coping strategies to climate variability and how they may structure future adaptations to climate change. We also investigate what types of households participate in those organizations and how their participation may impact their vulnerability to climate change and variability. Our analysis shows that in places rendered especially vulnerable to climate change by arid climatic conditions, the disengagement of governmental services, and a limited access to income-generating activities, local rural organizations increase livelihood security. Those organizations reduce local vulnerabilities and enhance collective action. In contrast to common diversification and livelihood security strategies which rely on the access to urban or peri-urban structures, local rural institutions and organizations allow for rural and grassroots sustainable adaptation strategies. In that respect, they constitute a resilient and mostly untapped resource for visibly strengthening livelihood security and adaptive capacities in rural Kenya.     

Shocks and coping strategies of coastal communities in war–conflict-affected areas of the north and east of Sri Lanka

A quantitative survey of 1,377 households in three war-affected coastal districts of Jaffna, Mannar and Trincomalee in the north and east of Sri Lanka shows that inflation or price hikes, specially fuel, and natural disasters such as floods and droughts are highlighted as the shocks with the biggest impacts on fisher and non-fisher households. We hypothesise that the pattern/severity of households’ coping strategies to face these shocks depends on a set of household characteristics: livelihood diversity, asset ownership, level of education and the ability to borrow. Livelihood diversity, asset ownership and borrowings correlate significantly with the severity of coping strategies adopted by households for both fisher and non-fisher households. Education and livelihood diversification does not show a significant correlation for fisher households although it significantly affects livelihood diversification of both types of households.     

Agricultural livelihood transition in the southern Yucatán region: diverging paths and their accompanying land changes

Land change science has demonstrated that rural livelihoods around the world both drive and reflect changing environmental regimes and political economic/structural transformations. This article explores the relationship between increasingly globalized rural livelihoods and in-place land change, assessing results from social surveys of smallholding households in the southern Yucatán region. We examine evidence for a transition in agricultural livelihood strategies as smallholders adjust to changing political economic and institutional conditions, and link these transitioning strategies to land use changes. Based on household surveys in 1997 and 2003, we comparatively assess both changes in the selection of livelihood strategies and in the land use and cover impacts of those strategies. Our results indicate that although impacts of given strategies have changed little over this period, there are increasing proportions of households pursuing two divergent adjustment paths—one of agricultural withdrawal and one of agricultural intensification and commercialization. We investigate what sociodemographic characteristics differentiate the groups of households following distinct livelihood strategies. Our findings point to the possibility of simultaneous and contradictory land change outcomes as smallholders adjust in different ways to their intensified incorporation into global economies.     

农户生计多样性发展阶段研究——基于脆弱性与适应性维度

为了观察农户生计活动复杂化过程,分析弹性在可持续生计中发挥的作用,推动扶贫开发战略从识别贫困人口向防御贫困转变,本文采用曲线拟合、核密度函数非参数估计算法等实证研究方法,利用陕西省安康农户生计与环境调查数据,基于脆弱性、适应性维度对农户生计多样性发展阶段进行了识别、划分,系统分析了弹性在农户、社区不同尺度上、阶段上对于农户生计脆弱性与适应性的作用过程。研究发现:生计多样性发展阶段随尺度有所不同,随着适应性提高,在社区尺度上,生计活动多样性指数先增加后减小,在农户尺度上,则是先减小后增加;农户生计活动存在高脆弱性、低适应性的尝试阶段,在经历了这个阶段之后,伴随着农户适应性的提高,脆弱性会同时增加;在社区尺度上,弹性作用下伴随着收入提高,脆弱性会逐步降低,在农户尺度上,弹性作用下伴随着收入提高,生计活动脆弱性会提高,形成"高风险、高收益"的情况。研究发现说明农户、社区存在着"多样性尝试"发展阶段,在一定尺度上保持适度脆弱性有利于社区、地域的可持续发展,作为联系不同尺度生计活动脆弱性、适应性的关键,农户在这个阶段完成生计多样性水平专业化过程,社区在这个阶段形成地区特色的生计活动。扶贫开发工作应把握好这一时机,提高工作措施效果和绩效。在扶贫开发工作实践中,在目标制定上不仅需要考虑收入因素,还需要考虑生计活动复杂性因素,政策措施充分利用"多样性尝试"发展时机,同时主动开展替代生计研究、落实工作,提高贫困防御能力,推动农户、社区可持续发展。     

Livelihood adaptations to climate variability: insights from farming households in Ghana

Climate variability poses a significant threat to many sectors of Sub-Saharan Africa’s economy. Agriculture is one of the most climate sensitive sectors because of its dependence on rain-fed cultivation. This paper identifies the main adaptation strategies used by farming households in the Sudan savannah and forest-savannah transitional agro-ecological zones of Ghana, in order to reduce the adverse impacts of climate variability on their livelihood activities. It combines questionnaire surveys, key informant interviews and a range of participatory methods. Results show that households employ a range of on- and off-farm adaptation strategies including changing the timing of planting, planting early maturing varieties, diversification of crops, support from family and friends, and changing their diets to manage climate variability. Results reveal that most households use adaptation strategies linked to livelihood diversification to adapt to the increased climate variability seen in recent decades. Most households now engage in multiple non-arable farming livelihood activities in an attempt to avoid destitution because of crop failure linked to climate variability (particularly drought). The findings suggest that policy makers need to formulate more targeted climate adaptation policies and programmes that are linked to enhancing livelihood diversification, as well as establishing communication routes for farming communities to better share their knowledge on successful local climate adaptation strategies.     

Climate change/variability and food systems: evidence from the Afram Plains,Ghana

While there are many studies of the impacts of climate change and variability on food production, few studies are devoted to a comprehensive assessment of impacts on food systems. Results of a survey of food systems and household adaptation strategies in three communities in the Afram Plains, Ghana, reveal how extreme climatic events affect rural food production, transportation, processing and storage. Adaptation strategies implemented by the three communities during past droughts serve as a foundation for planning responses to future climate change. Results of this study suggest that food security in this region—where droughts and floods are expected to become more severe due to climate change—could be enhanced by increasing farm-based storage facilities; improving the transportation system, especially feeder roads that link food production areas and major markets; providing farmers with early warning systems; extending credit to farmers; and the use of supplementary irrigation. This study also indicates that some cultural practices, particularly those that prohibit the consumption of certain foods, may reduce the resilience of some individuals and ethnic groups to food system disruptions. Understanding the local context and the responses of households is critical to the development of effective strategies for reducing the potential adverse impacts of climatic change on food security in rural Ghana.     

Livelihood strategies,environmental dependency and rural poverty: the case of two villages in rural Mozambique

This article attempts to explore the nexus between rural households’ environmental dependency, poverty and livelihood strategies. Households’ income from each livelihood activities formed the basis for categorizing households according to livelihood strategies. The principal component analysis, agglomerative hierarchical and the k-means cluster analysis were employed to determine the four livelihood clusters and to assign households to the identified livelihood strategies. Households’ environmental dependency, poverty and asset holding were compared across the strategies, and the determinants of livelihood choice were analyzed using multinomial logit model. The results indicate the existence of marked differences in environmental dependency, rural poverty and asset endowments across the livelihood groups. Household’s total saving, access to credit, production implements, business cost, exposure to agricultural shock determined household’s access to a more remunerative livelihood strategy. Incomes from each livelihood activities for the identified livelihood strategies were analyzed, and their implications were also discussed.     

Derivation of a household-level vulnerability index for empirically testing measures of adaptive capacity and vulnerability

Recent studies have projected significant climate change impacts in Africa. In order to understand what this means in terms of human well-being at local level, we need to understand how households can cope and adapt. This need has led many authors to argue for approaches to adaptation that are based on vulnerability analysis. Vulnerability is one of the key terms in the climate change literature, but little progress has been made in the field of its quantification. Typically, indicators are combined according to a weighing scheme, with the identification of indicators and the weighing schemes based on expert judgment rather than empirical evidence. In addition, most quantitative assessments are applied to countries or other administrative units, whereas managing climate risk has traditionally been the responsibility of households. We therefore focus on the adaptive capacity of households. We analyze the coping strategies and vulnerability to climatic stresses of agro-pastoralists in Mozambique and test the validity of a number of commonly used vulnerability indicators. We derive a household-level vulnerability index based on survey data. We find that only 9 out of 26 indicators tested exhibit a statistically significant relationship with households’ vulnerability. In total, they explain about one-third of the variation in vulnerability between households, confirming the need for more research on underlying determinants and processes of vulnerability. With inclusion of local knowledge, our study findings can be used for local targeting, priority setting and resource allocation. Complemented with studies analyzing climate change impacts and findings from country-level adaptive capacity studies, governmental policy can be informed.     

Unravelling the association between the impact of natural hazards and household poverty: evidence from the Indian Sundarban delta

Coastal regions have long been settled by humans due to their abundant resources for livelihoods, including agriculture, transportation, and rich biodiversity. However, natural and anthropogenic factors, such as climate change and sea-level rise, and land subsidence, population pressure, developmental activities, pose threats to coastal sustainability. Natural hazards, such as fluvial or coastal floods, impact poorer and more vulnerable communities greater than more affluent communities. Quantitative assessments of how natural hazards affect vulnerable communities in deltaic regions are still limited, hampering the design of effective management strategies to increase household and community resilience. Drawing from Driving Forces–Pressure–State–Impact–Response (DPSIR), we quantify the associations between household poverty and the likelihood of material and human loss following a natural hazard using new survey data from 783 households within Indian Sundarban Delta community. The results suggest that the poorest households are significantly more likely to endure material and human losses following a natural hazard and repeated losses of livelihood make them more vulnerable to future risk. The results further suggest that salinization, tidal surge, erosion, and household location are also significant predictors of economic and human losses. Given the current and projected impact of climate change and importance of delta regions as the world’s food baskets, poverty reduction and increase societal resilience should be a primary pathway to strengthen the resilience of the poorest populations inhabiting deltas.     

Non-timber forest product dependency in the Central Himalayan foot hills

Rural households throughout the Himalayas are regarded as dependent on non-timber forest products (NTFPs), but very few studies have quantified this dependency. This case study, undertaken in two villages in the Central Himalayan foot hills in Nepal, documents the absolute and relative importance of commercial NTFPs to rural household economies. Data were collected in a one-year period and included interviews with 250 households using a semi-structured questionnaire and monthly interviews with four sub-local NTFP traders, two local traders and two central wholesalers. The conservative estimate of NTFP-derived cash income showed this to be a cornerstone in poorer household livelihood strategies and thus in poverty prevention. An annual average of 578 kg of commercial NTFPs was collected in the wild per household, providing poorer households with a cash income share of 44–78%. Better off households are not NTFP dependent but rely on income from crop production and livestock. Based on a net marketing margin analysis, showing that harvesters capture a large share of the Indian wholesaler price, it is argued that there is scope for pursuing NTFP-based strategies for poverty reduction through leasehold forestry and agroforestry. Both these options are compatible with conserving forest cover and forest corridor functions and may thus present a win–win scenario for livelihood improvement and conservation.     

Local-level climate change adaptation decision-making and livelihoods in semi-arid areas in Zimbabwe

There is now overwhelming evidence of climate change and variability impacts in Africa, among them a reduction in agricultural production. This is a cause for concern given that 70 % of the continent’s population derives its livelihoods directly from rain-fed agriculture. There is need for adaptation strategies at all levels from the national to the local level to mitigate these adverse impacts from climate change. It is important to take advantage of and strengthen already existing household and community strategies. This study used both qualitative and quantitative methodologies to explore the role that livelihood dynamics play in local-level decision-making for adaptation to everyday vulnerability. Risk is considered to extend beyond climate to non-climatic stressors, and the notion of climate change as the major shock among many others is downgraded to one that is secondary to other shocks that even pose more danger to household and community livelihoods. The natural capital remains the basis upon which all the other capitals depend as drivers of choice for adaptation practices. A reorientation of capitals and associated activities is inevitable to deal with everyday vulnerability given that livelihood capitals play a key role in adaptation. Choice of household response strategies to shocks is not entirely intrinsic, but rather integral to a context where other players such as the extension operate to influence adaptation choices. This then highlights the need for embeddedness and context in understanding adaptation and livelihood changes.     

Local ecological knowledge and incremental adaptation to changing flood patterns in the Amazon delta

The need for understanding the factors that trigger human responses to climate change has opened inquiries on the role of indigenous and local ecological knowledge (ILK) in facilitating or constraining social adaptation processes. Answers to the question of how ILK is helping or limiting smallholders to cope with increasing disturbances to the local hydro-climatic regime remain very limited in adaptation and mitigation studies and interventions. Herein, we discuss a case study on ILK as a resource used by expert farmer-fishers (locally known as Caboclos) to cope with the increasing threats on their livelihoods and environments generated by changing flood patterns in the Amazon delta region. While expert farmer-fishers are increasingly exposed to shocks and stresses, their ILK plays a key role in mitigating impacts and in strengthening their adaptive responses that are leading to a process of incremental adaptation (PIA). We argue that ILK is the most valuable resource used by expert farmer-fishers to adapt the spatial configuration and composition of their land-/resource-use systems (agrodiversity) and their produced and managed resources (agrobiodiversity) at landscape, community and household levels. We based our findings on ILK on data recorded for over the last 30 years using detailed ethnographic methodologies and multitemporal landscape mapping. We found that the ILK of expert farmer-fishers and their “tradition of change” have facilitated the PIA to intensify a particular production system to optimize production across a broad range of flood conditions and at the same time to manage or conserve forests to produce resources and services.     

The survey of living conditions in the Arctic (SLiCA): A comparative sustainable livelihoods assessment

The Arctic is a region of the world experiencing extremely rapid climatic and social change. Indigenous communities have faced similar challenges for millennia and have historically demonstrated remarkable resilience to socioecological perturbations. In contemporary contexts, however, it appears that the pace and extent of change is overwhelming the adaptive capacities of many indigenous communities. Scholars recently completed a survey of living conditions spanning the circumpolar Arctic to quantitatively document the impacts of social and ecological stress across regions. The database they created is called the Survey of Living Conditions in the Arctic or SLiCA. This article explores the utility of using this dataset to compare livelihood systems across three sub-regions of Alaska and four sub-regions within the Chukotka Autonomous Okrug of the Russian Federation. The results point out that livelihood systems in Chukotka have a substantially lower level of sustainability than in Northwest Alaska due to the high prevalence of vulnerable households.     

Discovering and characterizing farm households’ resilience under water scarcity

Water scarcity at an alarming rate has been a limiting factor for sustainable agriculture in arid and semi-arid environments of the world. It has resulted in a number of problems such as poverty and food insecurity among farm households. Therefore, building and improving resilience, as a way to mitigate the impacts of water scarcity, is important for farm households. But one of the significant steps for planning to improve farm households’ resilience under water scarcity is investigation of the current level of resilience of these households and understanding their variances. Therefore, this study offers a classification of farm households’ diversity based on resilience. Primary data were collected from 260 randomly selected farm households in 21 villages around Parishan wetland, Iran. Farm Household Resilience Scale was used to measure resilience. Cluster analysis suggested three groups: highly, medium-, and low-resilient farm households. The results of comparing three groups revealed that highly resilient farm households characterize with higher risk management, more agricultural water security, more positive psychological traits, and better knowledge management. Also, they had better water quality, attended more agricultural extension activities, and used modern irrigation systems. Farm households’ resilience map using GIS software illustrated that there is a relationship between resilience and farm location from the wetland. The findings of this study could be used by planner and policy-makers to improve farm households’ resilience in arid and semi-arid environments. Improvement in knowledge management system is recommended as one of the most effective policy instruments in building resilience.     

多重压力下重点生态功能区农户的生计适应性研究——以甘南黄河水源补给区为例

重点生态功能区对维护国家和区域生态安全至关重要,农户作为该区最主要的经济活动主体和最基本的生态环境保护单元,其对生计压力的适应性直接关系到重点生态功能区主体功能的发挥。本文以地处青藏高原东缘的甘南黄河水源补给区为例,基于入户调查数据,分析了农户的生计压力、适应能力及适应策略,并利用多元logistic回归模型探明了影响适应策略选择的关键因素。结果表明:①甘南黄河水源补给区有近90%的农户遭受多重生计压力的冲击,其中,“自然+社会+经济”型压力是该区农户面临最多的生计压力组合。②经济示范区农户的适应能力最高,恢复治理区次之,重点保护区最低;遭受“自然+社会”型压力冲击的农户适应能力最高,遭受“自然+社会+经济+政策”型压力冲击的农户适应能力最低。③甘南黄河水源补给区有87.45%的农户采取多种适应策略来应对生计压力,其中,选择“扩张+援助+收缩”型适应策略的农户占比最大。④自然资本、人力资本、社会资本、自然压力的严重程度和生计压力的多样化程度是影响适应策略的关键因素。鉴于此,政府应加大生态环境保护力度,拓宽农户增收渠道,建立多元化信贷机制,加强偏远地区基础设施建设,完善社会保障体系,提高农户在面临生计压力时的适应能力,促进生计可持续发展。     

Is rainfall gradient a factor of livelihood diversification? Empirical evidence from around climatic hotspots in Indo-Gangetic Plains

Farmers in the Indo-Gangetic Plains are constantly seeking ways to adapt to changing circumstances and opportunities that include new technologies, institutions, policies, socio-economic and cultural shifts, as well as a changing climate. The relationship between rainfall and local livelihoods is important to devise policies to improve adaptive capacity of farmers to different drivers of changes. The present study investigates whether the spatial variations in rainfall have prompted the location-specific livelihood diversification by using data from 2660 farm families in the climatic risk areas in India, Nepal and Bangladesh. The results show a higher on-farm livelihood diversification in the areas with high rainfall (1500–2100 mm) compared to medium (900–1500 mm) and very high rainfall regimes (>2100 mm). Based on this study, the optimal range of rainfall for better agricultural livelihood in the context of changing environmental circumstances is from 1500 to 2100 mm. In terms of farm practices changed (proxy of adaptability), farmers responded more frequently to the market-related drivers than climatic stressors. Farmers in climate vulnerable areas (Bihar and coastal Bangladesh for instance) responded more to climatic stressors than those living in relatively less vulnerable areas (Terai for instance). The results imply that livelihood strategies should be tailor-made along the climatic resources such as rainfall, considering other biophysical and socio-economic variations at the spatial scale. Identifying household and farm-level coping strategies along the rainfall gradient can also be useful in targeting interventions to build resilience to shocks.     

Characterising the nature of household vulnerability to climate variability: empirical evidence from two regions of Ghana

This paper builds on national- and regional-level vulnerability assessments by developing and applying a livelihood vulnerability index at the community and household scales to explore the nature of climate vulnerability. It provides innovative methodological steps in relation to livelihood assessment to identify the vulnerability of households and communities to drought. This will help to improve drought vulnerability assessments in Ghana and more widely as it shows extra information can be obtained from local-level vulnerability assessment that may be lacking in national- and regional-level analysis. The research employs quantitative and qualitative data collected through participatory methods, key informant interviews and a questionnaire survey with 270 households across 6 communities in two regions in Ghana. Results show that within the same agroecological zone, households and communities experience different degrees of climate vulnerability. These differences can be largely explained by socioeconomic characteristics such as wealth and gender, as well as access to capital assets. Results identify vulnerable households within resilient communities as well as more resilient households within vulnerable communities. These outliers are studied in detail. It is found that outlier households in vulnerable communities have an array of alternative livelihood options and tend to be socially well connected, enabling them to take advantage of opportunities associated with environmental and economic changes. To sustain and enhance the livelihoods of vulnerable households and communities, policymakers need to identify and facilitate appropriate interventions that foster asset building, improve institutional capacity as well as build social capital.     

Adapting to declining fish resources: the differentiation of livelihood systems and fishing strategies in Singkarak Lake’s fishing community,West Sumatra

In Southeast Asia, inland fish resources are crucial for small-scale fishing households. Their decline, due to overfishing and a set of socio-ecological factors, jeopardises aquatic ecosystems and the livelihoods of fishing communities. Singkarak Lake (West Sumatra) exemplifies this sustainability challenge. The paper proposes a multi-disciplinary analysis of the situation. First, it identifies and documents the primary livelihood systems and the strategic adaptations involved in fishing communities. Based upon a sample of 200 households and the implementation of multivariate analyses, a typology is developed. Three household types are identified. Type I comprises better-off farming fishers that have high fishing capitals and income but the lowest returns on fishing and land assets. Type II includes poor fishing farmers with higher farming income; they show the highest return on land assets. Type III is composed of poorer, younger fishers with the highest return on fishing assets and fishing costs. They have little land, low farming income, and diversified livelihood sources. Second, the technical efficiency (TE) of fishing households is studied using a data envelopment analysis. The results show that the average TE is low, but marked differences exist between the types. Type I households have the lowest TE in fishing, confirming an extensification and overcapitalisation strategy. Type II households show a high technical fishing efficiency. They have developed on-farm diversification with a combined, balanced livelihood system. Type III households are the most efficient fishers. They developed an intensification strategy together with off-farm diversification. Different livelihood strategies and economic portfolio have been developed as the response to the limited resources, uncertainty, fluctuating environment and other source of vulnerability. The fishers built up their livelihood based on their assets’ ownership, access to other resource out of fishing and their socio-economic status. In this context, understanding livelihood diversity among small-scale fishers, different socio-economic, their efficiency, constraints and opportunities emerge as important factor in policy formulation to enhance support to small-scale fishing communities and improved management of both the resources and local development. Finally, the paper suggests a focus on people and community-related solutions and proposes a threefold approach of resource conservation, livelihood improvements and restructured governance.
