Food system transitions in deltas under pressure

Deltas are simultaneously the most promising and the most vulnerable places in the world. They are promising because they are home to fertile land, strategic harbours, excellent living conditions and are rich in biodiversity. However, they are vulnerable because to a host of threats, including floods, droughts, cyclones, tsunamis, earthquakes, salinity intrusion, rising sea levels and land subsidence. The number of people living in deltas is also growing, and their diets are changing.

Deltas are dynamic environments in which change is a constant. Development and adaptation processes in deltas have to find answers to how to deal with increasing challenges originating from a range of sources, including urban development and climate change. These developments put pressure on food systems and on agricultural and water management practices. This is true for the deltas in Bangladesh and Vietnam. There, salinisation, water quality issues, floods and droughts are driving the need for transitions in the current food systems.
