A survey was conducted to determine the effect of climate change on crop production and water quality in 12 villages of Deluty and Garaikhali unions under Paikgacha upazila of Khulna district, Bangladesh. Total of 100 farmers were interviewed using a pre-tested questionnaire. The climatic hazards as reported on the study area are salinity, cyclone, drought, hailstorm, river erosion and waterlogging, of them salinity is the most dominant hazard. Due to salinity the cropping system has undergone changes. Many crops and varieties have been either extinct or their cultivation has come down. Both soil and water are severely affected by salinity. Most of the farmers (90%) use pond water for irrigation and the majority farmers use pond and rain waters for drinking purpose. Results of the present study serves as a good basis for in-depth study to achieve successful crop production in the south west coastal area of Bangladesh.Res. Agric., Livest.

Abstract This study sought to understand the effectiveness of existing climate smart agricultural (CSA) practices used by smallholder farmers in Tehuledere District, north-eastern Ethiopia, using empirical data collected over 3 months in 2016. Both qualitative and quantitative data were collected from primary and secondary sources, including historical climatic records and perceptions, indicatiors of climate change, impacts and responses. The study employed focus group discussions and a household questionnaire survey during data collection. Findings reveal that the majority of participants are aware of climate change and variability. The indicators of climate change include drought, off-season rainfall, too little and/or too much rainfall, and high temperature. The impact of climate variability observed by participants include: (i) decreasing crop yields and livestock production; (ii) increasing pests and disease; and (iii) decreasing water quantity and quality. The adaptation measures embraced to mitigate negative climate change effects include: (i) changing crop varieties; (ii) integrating livestock and crop production; and (iii) soil and water conservation practices. As far as CSA practices were found to be viable and effective response measures, support from innovative polices and strategies should be emphasized so as to address the barriers and bring about widespread adoption.

Abstract. This paper examines the effects of climate change and drought on agricultural outputs in Spanish rural areas. By now the effects of drought as a response to climate change or policy restrictions have been analyzed through response functions considering direct effects on crop productivity and incomes. These changes also affect incomes distribution in the region and therefore modify the social structure. Here we consider this complementary indirect effect on social distribution of incomes which is essential in the long term. We estimate crop production functions for a range of Mediterranean crops in Spain and we use a decomposition of inequalities measure to estimate the impact of climate change and drought on yield disparities. This social aspect is important for climate change policies since it can be determinant for the public acceptance of certain adaptation measures in a context of drought. We provide the empirical estimations for the marginal effects of the two considered impacts: farms' income average and social income distribution. In our estimates we consider crop productivity response to both bio-physical and socio-economic aspects to analyze long term implications on both competitiveness and social disparities. We find disparities in the adaptation priorities depending on the crop and the region analyzed.

Africa is under pressure from climate stresses and is highly vulnerable to the impacts of climate change. In Kenya, agriculture is the backbone of the economy making it an important contributor to food security of rural households. Currently crop productivity is being affected by continued climate variations and decline in soil fertility. Adaptation to climate change requires to be given high and urgent priority for sustainable crop production. A study was conducted in Mavuria ward, Mbeere South Sub-County, Embu County to evaluate the effects of climate change adaptation on crop production. The study used both descriptive and experimental research designs. The primary data on adaptation measures was collected from farmers and institutions using questionnaires. In the data analysis, descriptive statistics were used to organize the climate data and that of the respondents into frequencies. Further, a Pearson correlation test was done to determine the relationship between farmer and institutional based mechanisms on adaptation to climate change at α=0.05. The main adaptation mechanisms identified were soil fertility improvement, soil and water conservation, early planting, pest and disease control, provision of certified seeds, and awareness creation. In view of these findings, the study recommends continuous implementation of these measures that can help strengthen farmers and institutional adaptation mechanisms towards climate change for improved crop production.

The World

The effects of climate change on agriculture are being witnessed all over the world. Rainfed agriculture is likely to be impacted severely in view of its’ high dependency on monsoon, the likelihood of increased extreme weather events due to aberrant behavior of south west monsoon. Anantapur, Akola, Solapur and Bijapur districts in India were selected for the study because, rainfed area is more than irrigated area and rainfall is the most critical factor affecting crop production in these districts. Major perceptions of climate change in the four rainfed study districts were prolonged dry spells, rise in temperatures, and delayed and shorter rains. Major adaptation measures towards climate change in four study districts were insurance, change in planting dates and cropping pattern. Majority of farmers positively agreed with attitude towards climate change statements which augurs well for current and future adaptation actions. As farm-level adaptation becomes an increasingly important across the world, policies at all levels will need to be accounted for appropriate factors, including perceptions and how perceptions affect human behavior and adaptive actions. Adaptation through transformation (in the present study diversify to livestock and work as labor) has the potential to become an inclusive, engaging and empowering process that contributes to alternative and sustainable development pathways which needs to be encouraged. The present findings contribute to research on climate change adaptation decision making both as a function of intra-individual processes such as knowledge, attitudes; and extra-individual factors like policies, infrastructure, information, forecasts etc. along with socio-economic contributory factors which deserve due attention in the light of scaling up adaptations.

Climate change is a recent challenge on crop production and productivity in the world. The objective of this paper is to review the major effects of climate change on the production and productivity of wheat in the high lands of Ethiopia. Effects of climate change on wheat would be mainly through changes in [CO2], temperature, rainfall, length of growing period, actual growth rate and increased evapo-transpiration, which may lead to reduce yield or complete crop failure. Moreover, flower fertilization and grain set are highly sensitive to heat stress during mid-anthesis. In C3 crops like wheat, the elevated CO2 level is expected to increase productivity as a result of higher CO2 diffusion through stomata leading to a higher photosynthesis rate. But, elevated [CO2] may have negative effects on the grain-quality of wheat in terms of protein, lipids, number of mitochondria and nitrogen contents. Unlike CO2, elevated temperature affects crop production negatively by increasing rate of respiration; hastening plant growth and development; increasing photorespiration of wheat, reducing photosynthetic efficiency due to O2 interrupts the photosynthetic path way instead of CO2, increasing rate of water loss by increasing evapo-transpiration and decreasing nutrient use-efficiency through increased rate of decomposition and mineralization. As a result, wheat area is forecast to be displaced by other crop types. In order to tackle this issue, major mitigation and adaptation measures for example promoting area closures and conservation agriculture-based (CA), agroforestry practices, efficient use of energy sources, etc. should be practiced and given special attention by the communities as well as the government to solve the effects of climate change on wheat production and productivity in the country.

The Impact

AbstractAgriculture is the backbone of Uganda’s economy, with about 24.9% contribution to the gross domestic product (GDP) as per the Uganda National Household Survey 2016/17. Agricultural productivity (yield per hectare) is still low due to the high dependence on rain-fed subsistence farming. Climate change is expected to further reduce the yield per hectare. Therefore, this study aims to evaluate the potential impact of climate change on maize yield in the Victoria Nile Sub-basin using the AquaCrop model. It further assesses the possible adaptation measures to climate change. The Hadley Centre Global Environmental Model version 2–Earth System (HadGEM2-ES) data downloaded from the Coordinated Regional Downscaling Experiment (CORDEX) was used to simulate maize yield in the near future (2021–2040), mid future (2041–2070) and late future (2071–2099). Results show that maize yield is likely to reduce by as high as 1–10%, 2–42% and 1–39% in the near, mid and late futures, respectively, depending on the agro-ecological zone. This decline in maize yield can have a significant impact on regional food security as well as socio-economic well-being since maize is a staple crop. The study also shows that improving soil fertility has no significant impact on maize yield under climate change. However, a combined application of supplementary irrigation and shifting the planting dates is a promising strategy to maintain food security and socio-economic development. This study presents important findings and adaptation strategies that policymakers and other stakeholders such as farmers can implement to abate the effects of climate change on crop production.

Purpose The purpose of this paper is understand these perceptions and identify main problems associated to climate change in order to design effective mitigation and adaptation strategies to guarantee the sustainability of tourism and natural resources. The Mediterranean basin is a leading international tourist destination and one that is particularly vulnerable to the effects of climate change. Although these effects are largely known, in-depth studies of how they and the associated risks are perceived by key tourism stakeholders have not been performed. Design/methodology/approach Interviews were held with 31 hotels, campsites and rural lodgings in the Muga River basin in north-east Catalonia, in which both owners and managers were asked about their perceptions of climate change, effects and countermeasures. Findings Perceptions of climate change and its effects varied according to the type of establishment and location (coast, cities or inland). Significant differences were observed for perceptions of how responsibilities for implementing mitigation and adaptation measures to counter the effects of climate change, including water shortages, should be shared out between the main agents with an interest in guaranteeing the sustainability of tourism, namely, government bodies, tourist establishments and clients. The predominant opinion, however, was that the bulk of the responsibility should lie with government bodies. Practical implications Only when those responsible for running tourist establishments are aware of the risks of climate change, it will be possible to design and implement effective short-, medium- and long-term strategies aimed at strengthening the resilience of the tourist industry. Originality/value The originality of this study lies in its novel methodology and approach, which involved analyzing perceptions of climate change, including water shortages and its effects among owners and managers of different types of tourist accommodation establishments in distinct parts of the same area.

Abstract. This paper examines the effects of climate change and drought on agricultural incomes in Spanish rural areas. Present research has focused on the effects of these extreme climatological events through response functions, considering effects on crop productivity and average incomes. Among the impacts of droughts, we focused on potential effects on income distribution. The study of the effects on abnormally dry periods is therefore needed in order to perform an analysis of diverse social aspects in the long term. We estimate crop production functions for a range of Mediterranean crops in Spain and we use a measure of the decomposition of inequality to estimate the impact of climate change and drought on yield disparities. Certain adaptation measures may require a better understanding of risks by the public to achieve general acceptance. We provide empirical estimations for the marginal effects of the two impacts considered: farms' average income and income distribution. Our estimates consider crop production response to both biophysical and socio-economic aspects to analyse long-term implications on competitiveness and disparities. As for the results, we find disparities in the adaptation priorities depending on the crop and the region analysed.
