Opis

Papyrus wetlands provide benefits to millions of people in Africa. The area is decreasing, while demand for food production increases. It is therefore urgent to combine increased agricultural production with wetland conservation. Field research findings and a dynamic simulation model support adaptive management for African wetlands.

O autorze

Edwin Hes obtained an MSc from Wageningen University in 1998, specializing in environmental science and technology. From 1999 to 2002 he worked for the Dutch Ministry of Economic Affairs as a public consultant on European research grants. In 2002, he started at IHE Delft Institute for Water Education and worked for the Liaison Office until 2007. Later that year, he started working as a Lecturer in Environmental Systems Analysis. His main research interests during the past years have been sustainable use of wetlands and modelling nutrient flows in wetland ecosystems, especially in papyrus wetlands in East Africa. He is interested in the use of models to study ecosystem functions and services and to evaluate social-ecological systems. At IHE Delft, he has been coordinating the Environmental Science programme from 2012 to 2016 and the joint degree programme in Limnology and Wetland Management from 2012 until present. Hes has been involved with teaching and training activities in the fields of Environmental Systems Analysis, Environmental Modelling and Wetland Management. In his educational activities he works with partner institutes from Kenya (Egrton University), Austria (BOKU), Mexico (LANCIS-UNAM) and the Netherlands (WUR-CDI). Since 2007 Hes has worked in research and capacity building projects in more than 20 countries in Asia, Africa and Latin America with a focus on sustainable use of wetlands. Mr Hes is an experienced facilitator and moderator in an international (development) setting.
