As Leader of Science Domain 1 – Agroforestry Systems, Fergus leads the Centre's research into the contribution that trees can make to the productivity of farming systems and rural people’s lives. This domain has two main areas of focus: soil and water productivity; and factors affecting farmer decisions about which trees they incorporate on their farms and how they manage them. He also co-ordinates the Smallholder Production Systems and Markets component of the CGIAR Research Programme on Forests, Trees and Agroforestry involving CIFOR, Bioversity and CIAT (http://www.cifor.org/crp6/crp.html) and is the ICRAF focal point for integrated agricultural research in the humid tropics led by IITA (http://www.humidtropics.org) and dryland systems, led by ICARDA (http://crp11.icarda.cgiar.org/crp/public/).
Fergus is well known for pioneering development of knowledge-based systems methods for acquisition and use of local agroecological knowledge (http://akt.bangor.ac.uk), for using participatory modelling to better harness natural resources at community level and for exploring trade-offs between the impact of farm trees on productivity and biodiversity. Recently, he has combined these interests by contributing to the development of interdisciplinary GIS tools for spatially explicit evaluation of ecosystem service synergies and trade-offs at landscape scales (Polyscape).

He works with the World Agroforestry Centre for part of his time through a research partnership with Bangor University, Wales, UK (http://www.bangor.ac.uk/) where is on the staff in the School of the Environment, Natural Resources and Geography. He is also a Visiting Professor at the Latin American Centre for Tropical Agricultural Research and Higher Education (CATIE) in Costa Rica (http://www.catie.ac.cr).
