This fall, professionals in PES and REDD are headed south. From across the globe  practitioners and policymakers in environmental markets are booking flights to  Colombia, Costa Rica, Argentina, Bolivia, and Mexico to discuss the future of  our world's ecosystems. In several cases, this is the first time that Latin  America is serving as host to these international conferences on environmental  markets. With a strengthening regional economy and four out of five of the  world's most bio-diverse countries, Latin America is becoming a major player in  REDD and PES.
