Water Sanitation Health

The burden of vector-borne diseases associated with irrigation schemes and large dams

at global and regional scale

WHO's Water, Sanitation and Health Unit and the Swiss Tropical Institute in Basel have completed a series of systematic literature reviews to arrive at a global picture of the vector-borne disease burden that may be attributed to water resources development projects.

A strengthened evidence base will help better define the health impacts associated with water resources that have been developed and are managed without due consideration of adverse health effects. It will also provide a solid foundation for the assessment of the efficiency of water-driven health interventions, including alternative design and construction options for irrigation schemes and dams, and improved water management practices.

It will allow:

  • a comparison between different options for “water interventions” and other medical and public health interventions.
  • elucidation of trade-offs, synergies and antagonisms whenever combinations of interventions are considered.
  • highlighting situations where options with only a marginal benefit to the production output of other sectors become highly desirable because of their added health benefits.

The results of the reviews of the burden of malaria and lymphatic filariasis are now available; those for Japanese encephalitis and schistosomiasis will be available shortly..
