Mainstreaming Environment for Poverty Reduction (MEPR) is a RETA financed by the Poverty and Environment Fund (PEF), a multi-donor trust fund administered by ADB. MEPR expands on the progress made under the Poverty and Environment Program, the first RETA funded under PEF, in promoting accelerated learning and innovative approaches on poverty-environment linkages. It is also opening up new opportunities for mainstreaming environmental considerations into ADB operations and business processes. Its grants program supports both pilot interventions and targeted analytical studies. The focal areas are: protection, conservation, and sustainable use of natural resources and ecosystem services; reduction of air and water pollution; and disaster prevention and reduction of vulnerability to natural hazards.
