The Basin Focal Projects (BFPs)
BFPs provide strategic research that
links project and basin activities and
provide insights on water, agriculture
and poverty in 10 diverse basins over
three continents
BFPs questions
• What links water, food and poverty?
• How well is water used?
• What are the foreseeable risks and
opportunities for change in basins?
Mekong - The wettest basin in the world where the poorest rely on sensitive
aquatic ecosystems such as the Tonle Sap.
Volta- 50% live below poverty line and the performance of rainfed agriculture
is only a small fraction of its potential.
São Francisco - Commercial agriculture forms a strong driver of change.
Karkheh - A water-short basin with added pressure from the strategic policy
goals of the government for self-sufficiency of food grain staples (e.g wheat).
Nile - One of the largest river basins in the World and 99% of its flow is shared
amongst 10 riparian countries. Huge evaporation losses in the Aswan Dam.
Limpopo - A basin with highly variable rainfall with frequent extreme events
(both floods and droughts).
Niger - More than 70 percent of the people in the riparian countries are below
the poverty line.
Andes - Economies transforming the lives of many while marginalizing some.
Indo-Ganges - Lifeline of more than 700 million people of which the majority
are rural.
Yellow River - Pressure on water from high economic growth.
