Dr. Andy Jarvis is the Leader of the Decision and Policy Analysis Program in the International Centre for Tropical Agriculture (CIAT) and is a Theme Leader on the CGIAR Research Program for Climate Change, Agriculture and Food Security, based in Cali, Colombia. Dr. Jarvis has 10 years experience of cutting edge scientific research in developing countries to support the goals of alleviating poverty and protecting essential ecosystem services of importance to humanity. His research has focused on the use of spatial analysis and environmental modeling to address issues such as agricultural biodiversity conservation, adaptation to climate change, and maintenance of ecosystem services. Over the past ten years Dr. Jarvis has published over 50 articles, book chapters or books, with over 20 of these in peer-reviewed articles published in international journals. Dr. Jarvis has also worked as a consultant to the Food and Agriculture Organisation (FAO) on developing climate change strategies to conserve agricultural biodiversity, and been a consultant on a variety of projects for the European Union, Global Environment Facility amongst others. In 2003 Dr. Jarvis won the Crop Science Society of America (CSSA) C-8 Genetic Resources award for best research paper stemming from his work on conservation prioritization research for wild peanuts in Latin America, and in 2009 received the prestigious Ebbe Nielsen award for innovative research in bioinformatics and biosystematics.

Jerome Touval is the Regional Science Director for Latin America at the Nature Conservancy (TNC). He has over 10 years of experience on key conservation issues. His work focuses on ensuring a consistent approach to conservation science across the regional program, sharing of best practices among staff, and focusing on generating the highest priority science required to address conservation management questions and decision-making. He also works with other conservation groups, government agencies and research institutions to identify priority areas for conservation, large-scale threats to biodiversity and opportunities for conservation.

Louis Reymondin is a Systems Engineer and PhD candidate in the Department of Geography at King's College of London. He has been working as a visiting researcher at CIAT for the last five years. During this time, his main research has been the design and implementation of an early warning monitoring system for habitat change detection across Latin-America (Terra-i). The implementation of this project involved the management and analysis of huge datasets (images of about 10 GB and one billion pixels each ) which have to be analyzed each 16 days for the last 10 years. This monitoring system has been fully implemented in Java and involved distributed programming (Java RMI). During his research, Louis Reymondin has been supervising the work of various students and recently graduated professionals working on specific components of the monitoring system.

Andres Perez-Uribe was born in 1971. He received a diploma in Electrical Engineering from the Universidad del Valle, Cali, Colombia, in 1993. He arrived in Switzerland in 1994 with a Swiss government fellowship and pursued research work with Professors Eduardo Sanchez and Daniel Mange at the Logic Systems Laboratory, Computer Science Department of the EPFL in the domain of artificial neural networks, autonomous mobile robotics, and reconfigurable circuits. He received a PhD degree in computer science from the EPFL in 1999 after completing his thesis on "Structure-adaptable Digital Neural Networks". In 2003 he became professor at the University of Applied Sciences of Western Switzerland (HEIG-VD / HES-SO). At HEIG-VD, he has taught courses on computer architecture, digital systems, bio-inspired systems, smart devices, machine intelligence, and has participated in the program Future Ingénieure, Egalité-HEIG-VD. He has participated as a lecturer on the Social psychology and Neurosciences doctoral schools of the Universities of Geneva and Lausanne, and is currently involved in several international research projects. He collaborates with the International Center for Tropical Agriculture (CIAT) in the development of Terra-i.

Mark Mulligan is Reader in Geography in the Environmental Monitoring, Modelling research group of the Department of Geography of King’s College London, UK. He has supervised some 21 PhD students and has a further 10 current PhD students including Louis Reymondin, all of whom work in policy-relevant environmental research. His research interests are in the application of environmental GIS, remote sensing and modelling to policy problems in water, agriculture and conservation. He has worked on these issues in the tropics since 1994 with funding from a range of sources and has published widely on these topics. During this time is has developed a series of widely used geo-databases ( and policy support systems ( to facilitate robust and effective policy-making in ecosystem services and water resources management.

Alejandro Coca is an Agricultural Engineer from National University of Colombia since 2011. During his bachelor internship he researched about the compilation and development of methodologies to determine and analyze the evolution of spatial patterns of habitat loss and human settlements in Latin America, focusing on deforestation, based on the data generated by the model Terra-i. Currently, he serves as a research assistant in CIAT and he is part of the team responsible for the download, generation and processing of data for further analysis.

Dr. Glenn Hyman has over 20 years of experience living and working in the Latin America tropics on issues related to agricultural development and environmental conservation. Glenn has worked on the trade-offs between smallholder farmer livelihoods and environmental concerns related to deforestation and forest degradation, and on land-use change and how it affects greenhouse gas emissions and farmer livelihoods. This work has been in conjunction with economists, ecologists and other professionals to put land-use change in the context of emissions and farmer incomes.

Glenn is currently coordinating CIAT’s participation in the Forests, Trees and Agroforestry Research (FTA) Program of the CGIAR. Glenn’s work within FTA focuses on participatory development of low emissions development strategies (LEDS), on monitoring reporting and verification (MRV) for REDD and ecosystem services programs, on land-use change impacts on multiple environmental services and on the development of the Sentinel Landscapes program.

Glenn currently works as the research coordinator leveraging Terra-i within FTA Program to compare forest cover patterns, processes and metrics with field research in eight “Sentinel Landscapes” across the tropics.
