The Ganges Delta polders are crucial for agricultural sustainability

The Ganges Delta polders are low-lying, protected areas vital for agriculture which face threats from salinity intrusion and waterlogging.

A workshop, organized by the International Water Management Institute, the International Rice Research Institute (IRRI) and the Institute for Water Modelling (IWM) Bangladesh, focused on using local-scale hydrological modeling to forecast salinity and inform agricultural decisions.

The workshop aimed to develop a collaborative approach using advanced hydrological modeling techniques alongside local knowledge and field data. This integrated approach is seen as crucial for managing the complexities of water and agriculture in the polders.

Mahesh Jampani, Syed Adil Mizan, Dipaka Ranjan Sena, Karthikeyan Matheswaran discuss how this workshop, as part of the CGIAR Initiative on Asian Mega-Deltas, marks a significant step in addressing critical modeling gaps and paves the way for developing sustainable water management strategies for the Ganges Delta polders.
