The aim of the ‘Water at the Heart’ collaboration is to address climate-related risks that too often fall between the cracks of most country-level water, sanitation and hygiene (WASH) policies. It will focus on practical, locally-driven action to better anticipate disasters and prepare communities well in advance. It will also use the latest science and technology to monitor and forecast weather and water-related hazards. It furthermore invests in communications technologies to warn communities of what is coming and enable early action. As a result, this programme is a direct contribution to the implementation of the UN Secretary General’s ‘Early Warnings for All’ initiative.
