“…It is found that these two policies fail to compensate to the climate change shock in all the selected South Asian countries. The results of the empirical model are aligned with Laborde et al (2012), Cai et al (2016 and Alvi et al (2020)…”

“…(1). Further, the lagged variables of temperature, precipitation and cereal yields are also taken into account to determine the longterm relation between climate change and cereal yields by following the work of Korhonen et al (2019) and Alvi et al (2020) in the field of climate change. The fixed effect dynamic model is shown as follows:…”

The present study develops an integrated assessment model (IAM) for food security under climate change for South Asia. For IAM, initially, an econometric model is estimated that identifies the impact of climate change on crop yields, using the historical relationships between temperature, precipitation, and the production of cereals. Subsequently, future projections have been collected for temperature and precipitation from climate models of the Coupled Model Inter-comparison Project Phase 5 (CMIP5), and the previous econometric model is applied to obtain the implied future cereal yields changes. Then, the yield variations are fed into a multiregional Global Trade Analysis Project (GTAP) model, calibrated to the GTAP 9 database, taking the form of decreases in factor-augmenting productivity of the grains sector. Further, the present study evaluates the effects of climate change on an individual South Asian country. The results indicate that change in climate decreases food production, increases food prices, decreases food consumption, and thus affects the welfare. Trade and fiscal policy responses are investigated to combat the problem of food security. It is revealed that these two policies fail to compensate climate change damage in all the selected South Asian countries.

“…The findings of this study corroborate with those of Schlenker and Roberts (2009) for the USA and Chen et al (2016) and Zhang et al (2017) for China. As the farmers are rotating their crops and people of developing countries are more concerned about the availability of overall grains (Alvi et al , 2020), it is important to see the impact of climate change on overall cereal yields. We ensembled the three cereal crops (maize, rice and wheat), and the results indicate that the GDD and precipitation affect the cereal yields significantly at a 99% confidence interval.…”

Purpose The first purpose of this study is to examine the impacts of climate-caused cereal productivity changes on food security, welfare and GDP in South Asian countries. The second purpose is to assess the agricultural subsidies and South Asia Free Trade Agreement (SAFTA) as policy responses to climate change. Design/methodology/approach The present study uses the computable general equilibrium (CGE) framework and econometric approach in an integrated manner to examine the economic impacts of climate-caused cereal productivity changes in South Asian countries. An econometric model is used to identify the impact of climate change on cereal yields and CGE approach is used to assess the future effect of climate change through simulations. In this course, the econometric findings are applied to Multiregional Global Trade Analysis Project 10 and then the model is calibrated for future projection. Findings The results indicate that there is a decrease in cereals production because of climate change and eventually it increases the prices of cereals, decreases the local consumption and GDP and, as a result, causes a loss in welfare. Subsidies and SAFTA have been found to have no substantial impact on increasing food security in South Asia. Originality/value The present study uses the concept of food demand for all cereals in an integrated way and focuses on the fiscal and trade policy responses to climate change.

“…However, in low-and middle-income countries, adaptive capacity is influenced by more than the individual capacity of farmers. Other factors, such as training, social and human capital, and credit facilities, can also influence this process [2,38,90]. For example, investing in irrigation was implemented by just over a third of the participants.…”

Climate Change Perceptions and Adaptation Strategies: A Mixed Methods Study with Subsistence Farmers in Rural Peru

et al. 2022

In Peru, subsistence farmers experience firsthand the direct and indirect impacts of climate change (CC). To understand how farmers adapt their livelihoods to climatic variability, this mixed methods study explored their perceptions and climate adaptability strategies implemented in Huayhuay, Peru. Twenty farmers participated in semi-structured interviews, and 103 completed a survey questionnaire. The results indicated that most farmers perceive changes in temperature, precipitation, and drought that negatively affect agricultural production and local natural resources. To deal with CC, farmers are implementing twenty-six climate adaptation strategies. Diversifying agricultural products and practices, and exploring new economic activities were adaptability strategies identified in this study that the literature has previously documented as having positive implications for agricultural livelihoods. However, some farmers reported that adaptability strategies are failed attempts at local climate action. The results, along with the adaptability literature, revealed that farmers implement locally accessible adaptability strategies based on their climate variability perceptions. Therefore, this study recommends exploring CC perceptions and adaptability strategies with a site-based approach. It is also recommended that future research, local climate planning, and action must focus on the efficiency and inclusiveness of strategies rather than their frequency or levels of adoption. Finally, strengthening the technical capacities and knowledge of CC among subsistence farmers must be a priority for authorities and practitioners in Huayhuay, Peru.
