This report provides a regional overview of food security in the mountains of the Hindu Kush Himalayan region under changing environmental and socio-economic conditions, and presents options to improve policy, actions, and knowledge to help improve food security in the region. Starting with a snapshot of agriculture and food security in the Hindu Kush Himalayas, the report then looks at some of the key global and local drivers influencing food security, including world markets, climate change, and social changes. It highlights that the Hindu Kush Himalayas has extremely varied social and ecological environments and often the mountainous areas of these countries have more in common with each other than with the other parts of their own countries. Despite facing similar challenges, however, there is often a lack of regional perspectives on common issues.
