is a landscape ecologist with a broad interest in plant community, forest and agricultural ecology, and using geographic information systems, remote sensing, and environmental modeling for landscape-level spatial analysis. He has many years experience working in the Himalayas, East Africa, South America and throughout Asia, including positions at the International Centre for Integrated Mountain Development in Nepal, the International Water Management Institute in Sri Lanka, and the International Centre for Research in Agroforestry in Kenya. He is currently a visiting professor at Kunming Institute of Botany and a Senior Landscape Ecologist with the World Agroforestry Centre East and Central Asia Region. His current interests focus on the application of advanced spatial tools at global to local levels, ecosystem management, and the impacts of climate change on terrestrial ecosystems and biodiversity conservation. Antonio Trabucco is a landscape ecologist with a strong background in global information systems and a wide scientific interest in the interactions between climate, natural/semi-natural ecosystems and human needs. He currently works as a junior scientist at the Euro-Mediterranean Center on Climate Change, investigating the impact of climate change on ecosystem services and agricultural production at Mediterranean and global scale. Richard Coe is a principal scientist and research methods specialist at the World Agroforestry Centre, Kenya, and the University of Reading, UK. He helps teams engaged in agricultural and environmental research improve the quality and effectiveness of their research through application of statistical principles during conception and design and in the analysis and interpretation of data. He has been doing this for many years. Frank Place is a senior economist at the World Agroforestry Centre headquarters in Nairobi, where he has been for 17 years. He currently heads the impact assessment unit which also oversees rural advisory services. In this capacity, he supports regional teams in impact assessment through the co-designing and implementation of research on the adoption and impacts of agroforestry as well as the impact of the Centre's research. He also undertakes policy research and support through the Agroforestry Policy Initiative. He received a PhD in Economics from the University of Wisconsin-Madison and worked with the World Bank and the Land Tenure Center prior to joining the World Agroforestry Centre.
