Professor Quan has served with the Natural Resources Institute for over twenty years, becoming a member of staff of the University of Greenwich when the Institute joined the University in 1996. During this time he has worked as a development researcher and practitioner, undertaking a wide range of consultancy and applied research assignments for a variety of international clients, including the African Union, FCDO, the European Union, FAO, IIED, SIDA, UNDP, UN Habitat, the World Bank and a number of developing country governments. From 1998 – 2003 whilst with the University, Dr Quan was commissioned to work as a Land Tenure and Policy Adviser with DFID (now FCDO, the Foreign, Commonwealth and Development Office). His previous postings have been with South Bank University's Local Economic Policy Unit, the Food Studies Group at Queen Elizabeth House, University of Oxford (seconded to UNICEF and the Mozambican Government) and with Oxfam, in addition to periods and working in community and housing development work and teaching in Further and Adult Education in inner London.

Professor Quan's work has focused on: land tenure, land rights and land policy; rural territorial development; rural institutions, policy and governance; local economic development; climate change adaptation and mitigation; rural livelihoods, community based natural resource management, development of smallholder agriculture, and rural extension in developing countries, particularly in sub-Saharan Africa and also in Latin America.Professor Quan is a specialist in lusophone countries, speaking fluent Portuguese and working extensively in Mozambique and Brazil. He takes an interdisciplinary perspective in development studies, drawing on perspectives and approaches in sociology, anthropology, geography and political science. He has collaborated extensively with leading researchers in these fields, including Camilla Toulmin and Lorenzo Cotula (IIED), Klaus Deininger (World Bank lead economist), Julio Berdegué (RIMISP, Chile) and Arilson Favareto (a leading Brazilian rural sociologist at UFABC, Sao Paulo), in addition to collaborating with researchers from the Institute of Development Studies at the University of Sussex and from the Programme for Land and Agrarian Studies at the University of Western Cape, South Africa.

Professor Quan's main research interests are in formal and informal institutions for natural resource and land management, land policy, agricultural development, and place-based or territorial development policies and approaches to rural development. I consider that my work shows the importance of sound institutional arrangements that respond to multiple stakeholder interests and manage them effectively are central to achieving more inclusive and sustainable rural economic and social development. In particular, decentralised institutional innovations at the meso- or landscape scale in a) farmer economic organisation, b) mechanisms and incentives for environmental management c) organisation of rural outreach / extension services, d) participatory decision making and governance arenas, and e) delivery and funding mechanisms for rural development programmes are essential in balancing agricultural development with the multiple demands on rural areas by establishing resilient development pathways that are socially inclusive and climate compatible.

Professor Quan's work on land tenure showed the continuing importance of customary institutions and practices in land and natural resource management, and the scope and need for their fuller integration into more formalised and inclusive land tenure and administration systems. His own investigations and his broader research leadership, including the organisation of a series of international conferences on land rights in Africa, and facilitation of an African research / policy / practitioner network on land in Africa had significant influence on international development policy on land at the beginning of the 21st Century.

The findings and insights of Professor Quan's work on land and on territorial development are important to establish and scale-up inclusive and sustainable rural development processes in developing countries, by balancing top-down sector-led with more bottom-up territorially focussed approaches, integrating the governance of land with broader territorial governance, and achieving multi-purpose sustainable land and natural use mosaics to meet social and economic need.
