Caroline King-Okumu provides advice, consultancy, research and writing contributions on dryland development issues to IUCN, WOCAT, UN, CGIAR and other international research and development projects and institutions. She is a Visiting Research Fellow at the Geodata Institute, University of Southampton, and is scoping transboundary resource management issues for a Not-for-Profit Think Tank based in Nairobi called The Borders Institute (TBI).

Her interests include integrated management of water and land in dryland ecosystems, environmental assessment (ecological and economic), groundwater management, sustainable land management, governance, institutional development and capacity building, and supporting efforts by decision-makers to think ahead to develop strategic plans under a changing climate and assessing the returns on investments in adaptation to climate change in water stressed and drought-prone dryland environments.

She has previously worked as a Senior Researcher on Dryland Ecosystems and Economic Assessment for the International Institute for Environment and Development (IIED), and managed large multi-country initiatives on dryland research and development for the International Centre for Agricultural Research in the Dry Areas (ICARDA) and the United Nations University International Institute on Water, Environment and Health (UNU-INWEH). Parts of her Doctoral fieldwork were hosted by the Institut des Regions Arides in Tunisia and by the University of Alexandria in Egypt.
