Several environmental development issues impact food security, especially issues such as climate change and exploitation of natural resources. Food insecurity also comes around from natural disasters, soil degradation, desertification, and other issues related to insufficient quality of farmland. Much of the work in this area deals with research on existing and potential impacts of the environment on food security. Others help communities gain capacity to deal with environmental factors that can negatively impact food access and sustainability, ensuring that farming does not have its own negative impacts on the environment and working to reverse environmental destruction that can lead to less crops and increased food insecurity.
