In south-west coastal Bangladesh around eight million people live inside polders – areas of land enclosed by embankments. These polders were constructed in the 1960s and 1970s to protect communities from tidal flooding and salinity intrusion. While they have brought benefits, such as increased agricultural production and improved transport, badly functioning polders have led to a number of problems.
Communities living in the polders today face multiple water-related hazards, ranging from chronic salinity affecting drinking water quality and reducing agricultural yields, to frequent floods and cyclones that destroy livelihoods and wipe out agricultural production. The interaction of water hazards together with lack of water availability in adequate quantity and quality has a big impact on poverty.
Addressing these coastal water security challenges requires an understanding of the complex dynamics between water security, human wellbeing and economic growth.
This study aims to improve understanding of how coastal water risks affect poverty, and to determine the best interventions for improving water security for the coastal poor. Ultimately, this research will help decision-makers make smarter investments in institutions and infrastructure, which not only reduce water risks, but also enable sustainable growth and improve lives.
We will develop a risk-based model of the dynamics of water, climate and poverty, and use the model to test the effectiveness of interventions. We will analyse trade-offs, combinations and sequences of investments such as resilient water infrastructure and drinking water supply systems.
