Groundwater plays a vital role in both water security and public health. In the face of climate change and unpredictability as well as growing demands and competition we are now seeing an increasing dependence on this resource at domestic level, by households that self-supply or opt to go off-grid. Thereby, these households are expected to meet their human right to safe drinking water. By ignoring the need to invest in groundwater resource monitoring and planning, governments are not only missing a tremendous opportunity but jeopardize water resources management of future generations. In a new article SIWI’s Dr Jenny Grönwall, Advisor on Water Policy and Rights, sheds light on the issue of groundwater self-supply through a human rights lens. The research for this article was supported by the UNDP-SIWI Water Governance Facility.
