This programme critically examines the role of agriculture (including horticulture) and agricultural research in addressing the major challenges and opportunities related to agricultural intensification and environmental sustainability particularly in tropical and subtropical regions of the developing world. It explains the role of agriculture in development, the different biophysical, economic and social environments in which agriculture is practised, elaborates recent developments in agricultural research and practice in response to challenges such as poverty, climate change and environmental sustainability, and describes the factors and processes that influence and enhance the relevance, quality and impact of agricultural research and farmer-innovation processes. Our programmes are excellent preparation for careers in international and rural development, agricultural economics, and marketing within the food chain and policy. Some 96% of our graduates are in work or further study six months after graduating.
