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.

Effects of Climate Change and Viarability on the Agricultural Production Systems provides an integrated assessment of global climate change's impact on agriculture at the farm level, in the context of farm level adaptation decisions. Ten agricultural areas in the Upper Midwest region - the heart of the United States' corn belt - were subjected to climate change and changing climate variability scenarios through simulations of future climate using results from general circulation models. Crop growth models, calibrated to the study sites, were used to simulate yields under varying climate conditions. Farm level production and economic analyses were performed to determine what adaptation strategies might be best utilized to maintain production and profitability for producers under conditions of global climate change and changing climate variability. Similar integrated analyses from Australia and Argentina provide comparisons from different regions.

Abstract: The authors explore how Latin American farmers adapt to climate by changing crops. They develop a multinomial choice model of farmer's choice of crops. Estimating the model across over 2,000 farmers in seven countries, they find that both temperature and precipitation affects the crops that Latin American farmers choose. Farmers choose fruits and vegetables in warmer locations and wheat and potatoes in cooler locations. Farms in wetter locations are more likely to grow rice, fruits, and squash, and in dryer locations maize and potatoes. Global warming will cause Latin American farmers to switch away from wheat and potatoes toward fruits and vegetables. Predictions of the impact of climate change must reflect not only changes in yields or net revenues per crop but also crop switching.

The portending process of climate change, induced by the anthropogenic accumulations of greenhouse gases in the atmosphere, is likely to generate effects that will cascade through the biosphere, impacting all life on earth and bearing upon human endeavors. Of special concern is the potential effect on agriculture and global food security. Anticipating these effects demands that scientists widen their field of vision and cooperate across disciplines to encompass increasingly complex interactions. Trans-disciplinary cooperation should aim to generate effective responses to the portending changes, including actions to mitigate the emissions of greenhouse gases and to adapt to those climate changes that cannot be avoided. This handbook presents an exposition of current research on the impacts, adaptation, and mitigation of climate change in relation to agroecosystems. It is offered as the first volume in what is intended to be an ongoing series dedicated to elucidating the interactions of climate change with a broad range of sectors and systems, and to developing and spurring effective responses to this global challenge. As the collective scientific and practical knowledge of the processes and responses involved continues to grow, future volumes in the series will address important aspects of the topic periodically over the coming years.
