Listing introduction
For Digbijoy, sustainable development is not only about expanding access – it is about enabling institutions, infrastructure and communities to thrive within environmental limits and respond to a changing climate.
Digbijoy Dey believes climate resilience and environmental responsibility must be embedded in every public service we design and deliver. For him, sustainable development is not only about expanding access – it is about enabling institutions, infrastructure and communities to thrive within environmental limits and respond to a changing climate. He works with governments, utilities and development partners to build practical, resilient and environmentally responsible service systems.
Digbijoy has more than 14 years of experience in climate-resilient water and sanitation systems, wastewater and environmental management across Bangladesh, Benin, Cambodia, Ethiopia, India, Indonesia, Nepal, Uganda, the Netherlands and Togo. Before joining Riva, he held technical and management roles within BRAC’s Water, Sanitation and Hygiene (WASH) programme, leading sanitation and wastewater initiatives at national scale. His expertise includes systems strengthening, climate adaptation, utility monitoring and evaluation, and sustainability assessment of projects and services.
He has advised programmes funded by the Embassy of the Kingdom of the Netherlands, the Bill & Melinda Gates Foundation, UNICEF, Water.org, UNOPS-WSSCC, Simavi and SNV. His work has contributed to citywide inclusive sanitation planning in Ethiopia and national faecal sludge management research and strategy development in Bangladesh.
