Jacinto studied environmental engineering at the University of Florida, specializing in wetland systems for water treatment and later earning a master’s degree in ecological engineering from the University of California, Berkeley. He was a Peace Corps volunteer in Cameroon, where he worked with communities on water and sanitation projects. Over the past four years he has focused on climate change, particularly in the areas of adaptation and REDD+. He has edited the book Adaptation to the Impacts of Climate Change on Wetlands in the Gulf of Mexico, published by the National Institute of Ecology in 2009, which allowed him to enter the climate change environment. He worked for two years for the government of Mexico in the design and evaluation of adaptation measures and policies at the national level and until recently was the Climate Change Adaptation Coordinator for WWF Mexico. At WWF he integrated climate change adaptation into conservation programs, supported federal and state governments in the development of adaptation policy instruments, particularly in connectivity strategies for protected areas. Since 2012, Jacinto has been working in the UN Environment Regional Office for Latin America and the Caribbean, mainly managing the Microfinance for Ecosystem-based Adaptation Project, which is being implemented in Latin America and Africa.
