AGRICULTURAL DROUGHT DISASTER AND FOOD SECURITY UNDER THE BACKGROUND OF GLOBAL WARMING——BASED ON PANEL DATA OF FIVE PROVINCES OF SOUTHWEST CHINA
利用1997-2008年中国西南五省面板数据，实证检验了农业干旱对粮食安全的影响，并提出了应对干旱风险的策略。
The drought disaster is the biggest risk of China's agricultural production,and it seriously affects the supply of agricultural products and food security.Through building econometrics model between agricultural drought and food security,and using the sample data of five provinces of southwest China,this paper empirically examines the effect of agriculture drought on food security from 1997 to 2008.The results show that the agriculture drought has significant effect on food security.Thus this paper puts forward the agricultural drought disaster risk strategy under the background of global warming: strengthening the infrastructure construction of farmland water conservancy works,reaching an aim to withstand agriculture drought risk through enhancing time and space allocation capacity of water resources;breeding drought-resistant crop varieties,improving crop drought endurance;adjusting grain production distribution,reducing the crops production on high water consumption in areas with high drought frequency.
