The national programme on payment for ecosystem services (PES) under ProArbol (the federal umbrella programme that promotes sustainable forestry), covers 3.25 million ha of forests and represents one of the largest PES programmes in the world. Other examples of economic instruments include a form of biodiversity offsets for projects involving deforestation - the Forest Land Use Change mechanism, reforestation programmes, controls on illegal hunting of wildlife, and fishery buybacks for more sustainable fisheries management. Some of these have produced positive results (e.g. reforestation), but there is insufficient evidence to fully evaluate the effectiveness of others (e.g. controls on illegal hunting of wildlife).
