Pieter van der Zaag PhD

Professor of Integrated Water Resources Management

Biography

Pieter van der Zaag is professor of integrated water resources management at the IHE Delft Institute for Water Education in Delft, The Netherlands, and also holds a professorship at Delft University of Technology. He chairs the Water Management Group.

Pieter has worked in Africa and Mexico from 1982 to 2003. He has special interests in agricultural water management, water allocation issues in catchment areas and in the management of transboundary river basins, on which he has published widely. Pieter is fascinated by the dynamic relationship between biophysical and social processes when managing water, and in understanding patterns of cooperation over water.

The following are Pieter’s current main research interests:

  • The role of inequality and heterogeneity in enduring water institutions
  • Harnessing water by smallholders from nature-based storage in (semi-)arid regions in Africa
  • Water allocation tools in river basins – developing dynamic water value maps
  • Water allocation in large irrigation systems – supporting canal operators with mobile model predictive control and earth observation techniques.

Pieter has a track record of formulating and guiding major interdisciplinary research and capacity building projects, including in Ethiopia, Ghana, India, Kenya, Mexico, Mozambique, Senegal, South Africa, Sudan, Tanzania, Vietnam and Zimbabwe.

He is member of the governing board of WaterNet in Southern Africa, associate editor of Water Policy, member of the editorial board of Hydrology and Earth System Sciences. From 2012 to 2018 he chaired the Netherlands National IHP Committee.

Pieter van der Zaag studied irrigation at Wageningen Agricultural University, The Netherlands. From 1987 to 1989 he was based in Mexico. He received his PhD degree in 1992. From 1993 he coordinated a joint research programme between the University of Zimbabwe and Wageningen Agricultural University.

In 1997 he joined IHE Delft and was seconded to the Department of Civil Engineering, again at the University of Zimbabwe. The major activity involved the setting up of a new MSc programme in ‘Water Resources Engineering and Management’.

From 1999 to 2002, Pieter was the interim manager of WaterNet, a regional network aiming to build and strengthen regional capacity for the integrated management of water resources in the Southern African region through education, training and research.

In 2002 Pieter van der Zaag was appointed Professor of Water Resources Engineering and Management at the University of Zimbabwe. In 2004 he was appointed Professor of Integrated Water Resources Management at IHE Delft. From 2012 to 2015 he was the head of the newly formed Department of Integrated Water Systems and Governance.
