Jeroen is a water resource engineer specialising in environmental health, with a particular focus on the association between water management and health. He completed his MSc at Wageningen University (the Netherlands) in 1999, following which he worked until 2006 for the International Water Management Institute (IWMI) in Pakistan, Vietnam, Sri Lanka and India. During this period he was involved in studies on malaria and irrigation system management, drinking water quality and childhood diarrhoea, and led trials to improve drinking water quality at village and household level (chlorination, improved sanitation and household storage). In May 2006 Jeroen completed his PhD at LSHTM on the use of untreated wastewater in agriculture in India and Pakistan. He now works as a research fellow at LSHTM.

SAFIR, EU FP-6

Safe and High Quality Food Production using Low Improved Irrigation Systems and Management (SAFIR) is a multi-country study of new technologies for using contaminated water for crop irrigation. The School is contributing to the health component in a programme of collaboration with several agricultural research institutes. Our input will be to assess the contamination-related risks potentially related to exposure to this water and consumption of contaminated crops. Field work will be carried out in several European countries and in China. The first stage will be a risk assessment based on modelling the exposure based on the pilot and field trial experiments and estimating potential exposure and health risk scenarios

ROSA, EU FP-6

Resource-Oriented Sanitation concepts for peri-urban areas in Africa (ROSA) has as objectives:

1. to promote resource-oriented sanitation concepts as a route to sustainable sanitation and to fulfil the UN MDGs,

2. to implement resource-oriented sanitation concepts in four model cities in East Africa (Arbaminch, Ethiopia; Nakuru, Kenya; Arusha, Tanzania; and Kitgum, Uganda),

3. to research the gaps for the implementation of resource-oriented sanitation concepts in peri-urban areas, and

4. to develop a generally applicable adaptable framework for the development of strategic sanitation & waste plans (SSWPs)
