Determinants of climate change adaptation strategies and its impact on the net farm income of rice farmers in south-west Nigeria

A multivariate probit (MVP) model was used to analyse the determinants of strategies adopted for adapting to climate change in a sample of smallholder rice farmers in south-west Nigeria. An efficient endogenous switching regression model (ESRM) was used to estimate the impact of climate change adaptation strategy on the net income of rice farmers. The MVP results show that the socio-economic factors, the institutional factors, and locational variables of some households statistically influenced the choice of climate change adaptation strategies employed. Complementarities among all the adaptation strategies used by the farmers were revealed by the positive pair-wise correlation matrix of the MVP model. The study also indicated that farmers affected by prolonged drought and incidences of flood were more likely to adopt adaptation strategies on their farmlands. The ESRM treatment effect indicated that the average net income per rice farm of those who adopted the strategies was significantly higher than that of those who did not. Thus, the government, stakeholders, and donor agencies must provide capacity-building innovations related to agricultural extension systems and climate change education through information and communication technologies. This investment in education is essential for development and would encourage farmers to adopt appropriate climate change adaptation strategies.     

How adjustments in land use patterns contribute to drought risk adaptation in a changing climate—A case study in China

In the context of climate change, adaptation to climatic extremes, such as drought, has attracted worldwide attention, yet many practical adaptation strategies need to be examined at the local level. Based on a case study of the village of Beidian, located in a drought-prone region in northern China, this study demonstrates that when faced with multiple pressures of regional climate change, drought risk and rural poverty, reasonable adjustments in land use patterns can serve as an effective adaptation strategy in the agricultural sector. We used household questionnaires, in-depth interviews with village managers, and land use surveys at the farming plot level to quantify the relationship between land use change and drought mitigation effects. Our findings indicate that in the past decade, the farming practices in Beidian have transformed from a complete reliance on the winter wheat–summer corn rotation to a new diversified mode of apple as the main crop and corn and coarse cereals as the subsidiary crops. The current farming mode is proven to possess a stronger adaptive capacity to drought due to its higher water-saving efficiency and economic benefit, which facilitates rural poverty reduction and socio-economic development. This study presents a feasible approach to address adaptation strategies at the local level, which provides policymakers with information on how to best support farm-level adaptation and to reduce farmers’ vulnerability to climatic extremes within the broader context of climate change.     

Farmers’ risk preferences and their climate change adaptation strategies in the Yongqiao District,China

Farmers’ risk preferences play an important role in agricultural production decisions. This study characterizes risk preferences among farmers in Yongqiao and determines how these risk preferences are related to their choices regarding climate change adaptation strategies. We find that most farmers in the study area were aware of climate change. They were taking measures to protect their livelihoods against perceived changes to the local climate. The risk experiment result shows that the representative subject was risk averse, and women were more risk averse than men. The relationships between farmers’ risk preferences and different climate change adaptation choices were different. Farmers’ risk aversion was negatively and significantly related with adaptation strategies on planting new crop varieties and adopting new technology, but it had a significantly positive effect on purchasing weather index crop insurance. The results also indicate that the level of education, farming experience, farm size, household income and perception of climate change impacts influence farmers’ adaptation decisions.     

Does social capital matter in climate change adaptation? A lesson from agricultural sector in Yogyakarta,Indonesia

Climate change increases the vulnerability of agricultural sector due to the increasing threat from pest attacks. Mitigation of a threat that results from climate change requires adaptation strategies. This study investigates farmers’ willingness to participate in the process of climate change adaptation in Yogyakarta, Indonesia; particularly in facing the increasing risk of pest attacks. Using a logistic regression model, we tested the impacts of social capital on farmers’ willingness to participate. The results showed that 70% of farmers were willing to contribute financially to the adaptation process. This participation was positively correlated with high social capital, which consists of high level of trust, community engagement, and personal relations with people in other villages. This study contributes to the literature by highlighting the potential roles of social capital in the process of climate change adaptation in agricultural sector.     

Farmers’ perception of effective drought policy implementation: A case study of 2009–2010 drought in Yunnan province,China

Using a qualitative social research method at the local administrative level, this paper provides insight into the policy process in China and farmers’ perceptions of the effectiveness of policies implemented to deal with drought. Two villages in rural South-West Yunnan were purposefully selected for the study. The research started with the general assumption that China has a strong top-down hierarchal approach to policy processes and that funding dispersal is prioritised by the central government. However, the study found that funding proposals are prioritised for selection in a bottom-up, participatory manner from the local level. The study also found that farmers’ perceptions of the effectiveness of policy implementation were directly related to their past experience. Among the nine indicators used to measure the effectiveness of policy implementation at the local level, the farmers in the study area perceived access to roads as highly effective; water use efficiency projects, market demand, human mobility for jobs, and government funds as moderately effective; drought knowledge, community participation in planning, and governance structures as least effective; and the role of leadership as not effective. The study found that farmers’ adaptation at the local level is oriented towards short-term market rewards and income diversification. Farmers’ local-level adaptation is guided by government priorities and driven by their perception of tangible benefits. To ensure the effectiveness of policy implementation, long-term adaptation strategies, such as awareness raising, capacity building, watershed management, and source conservation need to be strengthened at the local level.     

Adaptation strategies to climatic variability: A case study of small-scale farmers in rural Mexico

Climate change is predicted to have major consequences for small-scale farmers in the developing rural areas of the world. Rural areas, nonetheless, harbor opportunities to mitigate global climate changes. Identification of innovative adaptation strategies used by small-scale farmers, therefore, is crucial in order to understand the extent of their implications. This paper identifies the relationships between livelihood units and landscapes that they depend upon, in a small-scale farm community. It examines their experiences of increasing climatic variability, and how the different groups in the community are adapting to it. The study was conducted in a typical rural ejido community on the Pacific coast of Mexico (Ejido Ticuiz), where a detailed socio-cultural profile was obtained by means of semi-structured interviews. In the study area we encountered a range of individual and community-based adaptation strategies, built on farmers’ recognition of the different types of landscapes which supply goods and benefits. Small-scale farmers have used their landscape diversity to build adaptation strategies to guarantee the supply of goods and benefits to cope with uncertain of climate events. Households rather than individuals or the community as an institution were depicted as the core socio-cultural group for better understanding of patterns, behavior and aspirations related to climate change adaptation at local level. The adaptation capacities of rural communities could be significantly strengthened if political, financial and institutional support is targeted at households rather than at individuals or the community level only.     

Farm-level adaptation to climate change in Western Bangladesh: An analysis of adaptation dynamics,profitability and risks

Using long-term district-level climate data and a case study from a drought-prone village in western Bangladesh, this research explored trends in climate change, and analysed farmers’ adaptation dynamics, profitability and risks. This is the first study of its kind for drought-prone areas in Bangladesh.Farmers perceived climate changes included increases in temperature and decreases in rainfall which were as consistent with the trends of Chuadanga climate records. Farmers’ adaptation measures included changes in cropping systems, cropping calendars, crop varieties, agronomic practices, crop diversification and improved animal husbandry. Reducing environmental stress, ensuring self-sufficiency in staple crops (mainly rice) and other crop production practices, and enhancing economic viability of farm enterprises have underpinned these adaptations. Off-farm and non-farm wage employment, temporary migration, self-employment and educating children, constituted the core non-farm adaptation strategies.Emerging cropping systems like maize/cucumber and maize/stem amaranth/rice were economically more viable than the traditional rice/rice and rice/maize systems. Despite some uncertainties, farming was preferred to off-farm work, generating higher returns to labour for all cropping systems. Limited access to stress-tolerant varieties, extension services and affordable agricultural credit, combined with high production costs, variability in crop yields and output prices, are the main barriers to adaptation. Stronger agricultural research and support services, affordable credit, community-focussed farming education and training are critically important for effective adaptation to climate change.

Climate change adaptation actions by fish farmers: evidence from the Niger Delta Region of Nigeria

This paper examined climate change adaptation strategies in fish farming and the effect of such methods on the profit of fish farmers in the Niger Delta region of Nigeria, Africa’s most populous country. Using cross‐sectional data obtained from 420 fish farmers from the region and applying multivariate probit and instrumental variable regressions, the study found that fish farmers have adopted a broad range of strategies to address climate risk and that these have significantly increased farmers’ profit. Our findings indicated important relationships between certain farm, socio‐economic and institutional characteristics and the adaptation actions. The study provides useful insight into factors that potentially encourage the adoption of livelihood‐enhancing climate risk adaptation strategies by fish farmers in the Niger Delta region and similar contexts.     

Barriers and requirements to climate change adaptation of mountainous rural communities in developing countries: The case of the eastern Qinghai-Tibetan Plateau of China

Systematically identifying the barriers and requirements to adaptation is critical to the successful implementation of climate adaptation planning and policies at the local level, especially in the mountainous rural communities of developing countries with limited resources and technology. We conducted an empirical study of the barriers and requirements to adapting to climate change of 539 peasant households in an ecologically vulnerable area of China to enhance their resilience to climate change by improving our understanding of adaptation process and decision-making. Our findings indicated that farmers in the Gannan Plateau face multiple adaptation barriers, of which normative, information and technology barriers were more serious, such as lack of meteorological information service, infrastructure and technology extension in agriculture or animal husbandry. Adaptation requirements are an important way to effectively reduce or eliminate obstacles and improve farmers' adaptive capacity to climate change. The survey found that local households have an urgent requirement for infrastructure, information and production technologies, such as water, electricity, transportation facilities, disaster warning information, employment information and farming or breeding techniques. In addition, due to the influence of economic level, education level, years of farming, gender and other factors, differences exist in the adaptation barriers and requirements faced by farmers in different regions. These findings extend empirical evidence in favor of formulating a reasonable adaptation framework and choosing optimal adaptation strategies, which are essential for enacting well-targeted regional adaptation policies.     

How collective efficacy makes a difference in responses to water shortage due to climate change in southwest Iran

Climate change impacts the water sector in a manner that reduces the harvest and income of farmers, thereby exacerbating poverty and many other social problems. However, through adaptation measures, farmers can manage climate change impacts and thus reduce their vulnerability. To design effective public adaptation strategies, it is crucial to understand farmers’ behaviors at the farm level in response to water shortage due to climate change. Thus, the aim of this research is to accrue empirical evidence about farmers’ perceptions of and responses to water shortage due to climate change, using the Protection Motivation Theory. To increase the predictive power of the model, this paper added the collective efficacy variable to the model. The population of interest consisted of farmers from Shushtar, a county in Khuzestan Province, southwestern Iran. A total of 251 farmers were selected using a multi-stage, clustered, random sampling method. The results of structural equation modeling revealed that model variables accounted for 39 % of variance in farmers’ adaptation behaviors. The inclusion of collective efficacy in the original model increased its predictive power and produced a model of a better fit; the proportion of variance accounted for an increase of about 11 %. These findings are expected to yield recommendations for public policy, as well as agricultural extension and education recommendations for stimulating successful adaptation behaviors among Iranian farmers.     

Understanding the adoption of climate change adaptation strategies among smallholder farmers: Evidence from land reform beneficiaries in South Africa

Climatic change has a negative impact on people’s livelihoods, agriculture, freshwater supply and other natural resources that are important for human survival. Therefore, understanding how rural smallholder farmers perceive climate change, climate variability, and factors that influence their choices would facilitate a better understanding of how these farmers adapt to the negative impacts of climate change. A Zero-inflated double hurdle model was employed to estimate the factors influencing farmers’ adoption of adaptation strategies and intensity of adoption at the household level in South Africa. Different socioeconomic factors such as gender, age, and experience in crop farming, institutional factors like access to extension services, and access to climate change information significantly influenced the adoption of climate change adaptation strategies among beneficiaries of land reform in South Africa. Concerning intensity of adoption, age, educational level, farming experience, on-farm training, off-farm income, access to information through ICT and locational variables are the significant determinants of intensity of adaptation strategies. Thus, education attainment, non-farm employment, farming experience are significant incentives to enhance smallholder farmers' adaptive capacity through the adoption of many adaptation approaches. This study therefore concluded that farm-level policy efforts that aim to improve rural development should focus on farmers’ education, on-farm demonstration and non-farm employment opportunities that seek to engage the farmers, particularly during the off-cropping season. The income from non-farm employment can be plough-back into farm operations such as the adoption of soil and water conservation, use of improved planting varieties, insurance, among others to mitigate climate variability and subsequently increase productivity. Policies and investment strategies of the government should be geared towards supporting education, providing on-farm demonstration trainings, and disseminating information about climate change adaptation strategies, particularly for smallholder farmers in the country. Thus, the government, stakeholders, and donor agencies must provide capacity-building innovations around the agricultural extension system and education on climate change using information and communication technologies.

Climate precarity in rural livelihoods: Agrarian transformations and smallholder vulnerability in Vietnam

In recent decades, agrarian transformations in Southeast Asia have resulted in significant environmental and social change, yet insufficient attention has focused on the particular pathways by which these changes have increased vulnerability to climate change. In particular, climate precarity, a situation in which class, social, labour and/or gender inequities amplify negative impacts from climate change, has been on the rise for many smallholders. Using case studies in Vietnam of changes to swidden agriculture in upland areas and the loss of deepwater rice systems in the Mekong Delta lowlands, the paper examines social differentiation and ecological outcomes of these processes and how they have increased climate precarity, particularly for poor households and women. Based on longitudinal fieldwork in affected regions, we identify key changes contributing to climate precarity as farming systems intensify. In particular, loss of flexibility in farmer decision-making, loss of voluntary engagement with markets, and declining access to social capital and entitlements have increased risks for households and reduced adaptation options. Suggestions are made to more directly address these elements in future agricultural and climate policies, rather than current approaches to climate adaptation that often promote even more intensification of agriculture, which runs the risk of exacerbating precarity.     

Determinants and implications of crop production loss: An empirical exploration using ordered probit analysis

This study investigates farmers’ perception about the severity of loss for three rice crops, identifies their determinants and explores policy implications based on findings. This research employs an ordered probit model to data collected from 1800 farm households from drought-prone and groundwater depleted areas of Bangladesh. This is the first study of its kind.Severity of rice production loss, while differing across all three rice crops, was higher for rain-fed crops. This was broadly consistent with available independent evidence. Geophysical factors, household characteristics, institutional and market accessibility, and household adaptation strategy were key determinants of crop loss. The impact of these factors was specific to the crop and severity of loss.This study has several policy implications involving market, R & D and institutional support based options. Strengthening support systems for institutional and market accessibility, and science driven climate change adaptation strategy including generation and wider dissemination of drought tolerant rice varieties, and enhancing farmers’ capacity to change rice varieties on a regular basis, constitute key areas for policy intervention.     

陕南生态移民土地经营权转让意愿及其影响因素研究——以汉中市为例

文章在对生态移民土地经营权转让意愿及其影响因素进行理论分析的基础上,基于对陕南地区汉中市6个生态移民搬迁安置点258户搬迁农民的实地调研数据,运用Logistic二元回归模型对生态移民转让土地经营权的意愿及其因素进行实证分析。结果表明:陕南地区生态移民转让土地经营权的意愿普遍较低,这对进行生态移民后原居住地的土地整理、实现土地的适度规模经营是十分不利的,而职业非农化程度、家庭非农收入比、安置点经济情况、拥有社保情况和土地经营权转让价金等5个因素是影响生态移民是否转让土地经营权的主要因素。在此基础上,文章从严把移民安置选点关、努力提升安置质量,加强后续产业发展、提高就业容量,建立健全移民社会保障政策、维护移民合法权益,完善土地流转市场、发展多样化的土地转让模式等方面提出促进搬迁农户土地经营权合理流转,提高农地资源配置效率的对策建议。     

Sustainable agricultural practices,environmental risk mitigation and livelihood improvements: Empirical evidence from Northern Ethiopia

Using sustainable agriculture practices has various economic, social and environmental benefits. Determining the attitude of farmers toward risk is an important first step in understanding their behaviour and coping strategies to mitigate environmental risks. This paper investigates the dual impacts of some agricultural practices on agricultural yields and farmers’ livelihoods considering sustainable farmland. Cross-sectional data is collected from farmers in six rural villages in Tigray region, Northern Ethiopia using structured questionnaires. Results show that education, labour supply, agricultural extension services, attitudes, social capital, risk mitigation attitudes, farming experience and soil conditions are factors that significantly affect farmers’ decisions to adopt these practices. The practices are adopted either in isolation or jointly of integrated sustainable practices that increase crop production, household income and asset. Therefore, government and other development actors should promote their adoptions especially in drought-prone, degraded and water-stressed areas

Climate change adaptation in agriculture: A computable general equilibrium analysis of land-use change in Nepal

This paper investigates the feasibility of changes in cropland-use as an adaptation strategy to minimise the economy-wide costs of climate change on agriculture. Nepal makes an interesting case study as it is one of the most vulnerable agricultural economies within South Asia. We develop a comparative static multi-household computable general equilibrium (CGE) model for Nepal, with a nested set of constant elasticity of transformation (CET) functional forms, to model the allocation of land within different agricultural sectors. Land transformation elasticities in these CET functions are allowed to reflect the ease of switching from one crop to another based on their agronomic characteristics. The results suggest that, in the long run, farmers in Nepal tend to allocate land to crops that are comparatively less impacted by climate change, such as paddy, thereby minimising the economy-wide impacts of climate change. Furthermore, the results reveal that land-use change tends to reduce the income disparity between different household groups by significantly moderating the income losses of marginal farmers. Therefore, it is suggested that policy makers in Nepal should prioritise schemes such as providing climate-smart paddy varieties (i.e., those that are resistant to heat, drought and floods) to farmers, subsidising fertilizers, improving agronomic practices, and educating farmers to switch from crops that are highly impacted by climate change to those that are not, such as paddy.
