This blog from the Biodiversity and Ecosystem Services Program (BIO) at the Inter-American Development Bank (IDB) is meant to provide a forum for people working on the cusp of mainstreaming natural capital in development. The work of BIO is coming up with promising findings on subjects as varied as measuring the benefits of various clean-up options of a lake in Paraguay, examining whether the fisheries value of freshwater rivers in the Amazon can be taken into account in hydropower planning and how can small farmers in Uruguay contribute to erosion control and carbon sequestration. And there are promising developments from partners all over the Region. This blog convenes specialists from both IDB and the organizations we partner with.
