Drinking water scarcity in prosperous urban areas is an increasing challenge for cities around the world. This situation, exacerbated by growing climatic extremes, is prevalent in the Rio Lurin catchment area in Lima (Peru), which is the world’s second largest desert city. The TRUST research project is exploiting the possibilities for developing an innovative solution to secure the drinking water supply and expedient disposal of water in the catchment area of the Rio Lurin, one of Lima’s three major drinking water sources. Using remote sensing and hydrological modelling in combination with strategic decision-making tools, the team of researchers and practitioners of natural sciences, engineering and social sciences has made significant progress in the project’s first year.
