THE IMPACT OF CLIMATE CHANGE ON AFRICAN AGRICULTURE: A RICARDIAN APPROACH1 David Maddison, Marita Manley and Pradeep Kurukulasuriya2 1 An earlier version of this Working Paper was published as CEEPA Discussion Paper number 15. Impact of agriculture on climate change. Climate change is one of the biggest challenges the world faces today posing a threat to many populations around the globe. Climate change and agriculture Based on some of the past experiences indicated above, impact of climate change on agriculture will be one of the major deciding factors influencing the future food security of mankind on the earth. Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) A2 scenario which represents CO 2 e levels higher than 500 ppm by mid-century. The crops, livestock, and seafood produced in the United States contribute more than $300 billion to the economy each year. To help fill this gap, a team of scientists from the Commonwealth Scientific and Industrial Research Organisation and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) has reviewed the risk of climate-related impacts … Areas where yields are projected to decline (warmer colors) include some of our most important agricultural regions, such as the Corn Belt and California's Central Valley. 2012-02-15 - Several studies have analyzed the effects and showed the main findings of ongoing climate change. Other chapters in this volume specifically address the context in which future agricultural systems will be affected by climate change, evaluating trends in socioeconomic conditions, demand for agricultural products, characteris- Predicted rates of climate change exceed any of the observed rates of change of the past 420,000 years (Petit et al. Increased temperatures, especially in the number of extreme hot days, as well as changes in precipitation, are the main climatic variables affecting agriculture on the African continent. However, in spite of these weaknesses, it can be used to analyze the effects of climate change on agriculture and still widely used in … Climate Change and Agriculture imPACtS, ADAPtAtiOn AnD mitigAtiOn by Anita Wreford, Dominic moran and neil Adger Climate change is likely to have significant impacts on the agricultural sector to which farmers will have to adapt. Climate change has a significant impact on agricultural systems as it affects both plant and animal health. Water availability, degree days, and the potential impact of climate change on irrigated agriculture in Hanemann, A.C. Fisher. While climate change and weather variation are two different issues, one phenomenon of climate change is the increasing frequency of weather shocks (extreme weather). 1. The impacts of climate change on water resources, in turn, affect all major sectors of the economy. Agriculture both contributes to and is vulnerable to climate change. Moving Target. It contributes to climate change because it is a source of the greenhouse gases carbon dioxide (CO 2), methane (CH 4), and nitrous oxide (N 2 O). All of these sectors except energy involve land. • Only recently have climate change impacts on agriculture been assessed comparatively under both unconstrained and constrained pathways. 2010). California Climate Change Center. When food-service and other agriculture-related industries are included, the agricultural and food sectors contribute more than $750 billion to the gross domestic product. Thermal expansion of the upper ocean due to climate change leads to a rise in sea level and the subsequent invasion of saltwater into freshwater horizons, reducing the quantity and quality of their reserves. Agriculture and fisheries are highly dependent on the climate. We investigate the contribution of economic models to uncertainty in this impact chain. Agriculture: Vulnerability to Climate Change Introduction. Warmer air can hold a higher water content, which makes rainfall patterns more extreme. These panel estimates incorporate farmers within-year adaptations to annual weather shocks. In the nine economic models included, the direction of management intensity, area, consumption, and international trade responses to harmonized crop yield shocks from climate change … Therefore, it is critical to consider the case of extreme weather in addressing the effect of climate on agricultural productivity. Extreme weather conditions and changing patterns of precipitation lead to a decrease in the crop productivity. A vicious cycle that makes agriculture both a victim (given the negative effects of global warming on food supply) and a perpetrator (one of the main causes of climate change). Introduction. Early analysts of climate impacts identified five sectors of the economy that are sensitive to climate change: agriculture, forestry, water, coastal, and energy (Pearce et al. 2011).As a result, climate change may become one of the most important determinants for the distribution of arable weeds (Pautasso et al. 2007. • While increases in atmospheric CO 2 are projected to stimulate growth and improve water use efficiency in some crop species, climate impacts, particularly heat waves, droughts and and life as a result of climate change Concerted global action is needed to enable developing countries to adapt to the effects of climate change that are happening now and will worsen in the future. It is clear that the fast pace of climate change will have far reaching impact on agro-ecosystems and their productivity. The flow of the impacts of climate change on the agricultural sector can be illustrated as shown in

. Meanwhile, these factors have an inevitable impact on crop yield or the adaptation of the farmers either directly or indirectly. 2 Respectively, the Department of Economics, University of Birmingham; the UK Department of Trade and Industry; and the UN Development Program. The urgency for adaptation is highlighted by projections from the three reports produced by the IPCC in 2007 (IPCC 2007). Although some regions and crops will benefit, most will not. Plausible estimates of climate change impacts on agriculture require integrated use of climate, crop, and economic models. It is highly likely that global climate change will generate different impacts on regional, physical, and biological systems, and the gravity of these impacts will vary considerably in relation to … Consequently, much research has focused on China's influence on climate change but somewhat less has been written about the impact of climate change on China. • Constrained pathways represent effective international • The net effect of climate change on world agriculture is likely to be negative. Agriculture is one of the main sources of emitted methane and nitrous oxide. Climate change and agriculture are strongly co-related.
