Agriculture in Central Asia is vulnerable to climate change due to rising aridity, declining availability of water resources for irrigation, and low adaptive capacity. We use climate data from CMIP5 with RCP8.5 for greenhouse gas emissions and the DSSAT crop model to investigate how yields of key crops in Central Asia will be affected by climate change. We distinguish changes in yields between spring and winter plantings, between irrigated and rainfed crops, and between crops grown with high and low amounts of fertilizer. The results suggest that countries (and areas within countries) that either have moderate summers or grow a number of crops in a relatively cold winter will benefit from climate change, while countries that grow many of the crops in the summer will experience losses.

Agriculture is one of the most climate-sensitive of all economic sectors. In many countries, such as the four examined in Looking Beyond the Horizon, the risks of climate change are an immediate and fundamental problem because the majority of the rural population depends either directly or indirectly on agriculture for its livelihood. The risks of climate change to agriculture cannot be eff ectively dealt with--and the opportunities cannot be eff ectively exploited--without a clear plan for aligning agricultural policies with climate change, developing the capabilities of key agricultural institutions, and investing in infrastructure, support services, and on-farm improvements. Developing such a plan ideally involves a combination of high-quality quantitative analysis; consultation with key stakeholders, particularly farmers and local agricultural experts; and investments in both human and physical capital. The diverse experiences of Albania, the former Yugoslav Republic of Macedonia, Moldova, and Uzbekistan, highlighted in this book, show that it is possible to develop a plan to meet these objectives--one that is comprehensive and empirically driven as well as consultative and quick to develop. The approach of this volume is predicated on strong country ownership and participation, and is defi ned by its emphasis on "win-win" or "no regrets" solutions to the multiple challenges posed by climate change for the farmers of Eastern Europe and Central Asia. The solutions are measures that increase resilience to future climate change, boost current productivity despite the greater climate variability already occurring, and limit greenhouse gas emissions--also known as "climate-smart agriculture." Looking Beyond the Horizon draws on the experiences of applying this approach to these four nations in Eastern Europe and Central Asia with the goal of helping each country mainstream climate change adaptation into its agricultural policies, programs, and investments. The book also highlights the projected impacts of climate change on agriculture in these countries through forecast variations in temperature and rainfall patterns, which are crucial to farming, and off ers a map for navigating the risks and realizing the opportunities. Finally, a detailed e xplanation of the approach, as well as lessons learned from its implementation, is provided for those who would like to implement similar programs in other countries of Europe, Central Asia, or anywhere else in the world.

The effect of recent climate change in Central Asia poses a significant and potentially serious challenge to the region's agricultural sector. An investigation of the aerosol-climate- crop yield correlation in this region is essential for a better understanding of the effect of aerosols and climate on Central Asian agriculture. Our goal is to investigate the linkages between aerosol, climate and major crop production (cotton, maize, wheat, and rice) in specified agricultural regions in the five Central Asian countries. Our approach is to perform the Pearson's Correlation Coefficient analysis in order to observe the statistical correlation between crop yield, temperature, precipitation, and aerosol optical depth (AOD), for each indicated agricultural region in the selected countries. Besides, using NASA GIOVANNI website tools, we retrieve distribution maps and time series of temperature, precipitation and AOD to facilitate the analyses. The research shows that in some aspects, the relation between AOD, climate, and crop yield is different in Central Asia than in previous global or large scale research hypotheses. The statistical correlations vary not only across countries but also across agricultural regions. For example, in Kazakhstan, opposite correlations exist between precipitation and AOD in two different agricultural regions even though both regions are rain-fed. In the more arid countries (with lower rain rates) such as Turkmenistan and Uzbekistan, no correlation exists between crop production and temperature, precipitation, and AOD, while the less arid (with higher rain rate) countries (Kazakhstan, Kyrgyzstan, and Tajikistan) indicate a positive correlation.

To ensure the viability and competitiveness of agriculture and forestry and sustain rural livelihoods, it is critical to take stock of the impacts of climate change on rural sectors in Europe and Central Asia (ECA) countries and implement appropriate adaptive measures. The interactions between the weather-sensitive agriculture and forestry sectors, climate change, and the natural resource base are highly complex and deserve special attention. Globally, the increased frequency of heat stress, droughts and flooding events caused by climate change threaten to reduce crop yields and livestock productivity in many areas, while increased risks of fires and pest outbreaks will have negative consequences for forests. In this paper, the authors examine the exposure, sensitivity, and adaptive capacity of ECA agriculture to climate change, and provide recommendations for addressing the challenges of climate through adaptation. We have made use of the best available climate change projections to categorize countries in the region by likely agricultural sector impacts. We have also attempted to synthesize information from the literature on climate change adaptation in agriculture in order to identify the most relevant points for ECA countries, including options for technical, institutional and policy measures. Based on this initial assessment, there are plans to support World Bank clients in carrying out assessments and developing strategies at the country level in the near future.

Agriculture and climate changes are closely linked. Agriculture has a significant impact on the process of climate change. There is uncertainty surrounding the implications of climate change for agricultural production. This document consists of two studies on this relationship. The first study provides an analysis of the various methodologies that have been used to measure the potential impacts of climate change on agricultural production and makes suggestions for further research. The second study is on the impact of agriculture on climate. It gives a detailed analysis of the potential for implementing the Clean Development Mechanism proposed under the Kyoto Protocol Convention on Climate Change in the agricultural sector of developing countries along with the relevant policy implications and requirements
