Amid a global climate crisis, more frequent and intense heat waves alter people's quality of life and increase morbidity and mortality. Cities are particularly vulnerable to heat because they concentrate people, including many in situations of individual, social and/or environmental fragility, and because the urban fabric, structure, cover and metabolism alter the thermal environment, which generally exacerbates heat stress. Creating cities that sustainably and effectively address the challenge of overheating is thus of utmost importance.

The overall goal of MULTISOURCE is to, together with local, national, and international stakeholders, demonstrate a variety of Enhanced Natural Treatment Solutions (ENTS) treating a wide range of urban waters and to develop innovative tools, methods, and business models that support citywide planning and long-term operations and maintenance of nature-based solutions for water treatment, storage, and reuse in urban areas worldwide.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement N° 101003527.
