Waste Water Used for Green Production in Cities

Dear Colleagues,

How can we use wastewaters for green production in cities? In 2020, the management of domestic wastewaters and rainwaters remains a major global challenge, in addition to feeding the poorest populations, or stopping soil losses occurring through the rapid urbanization and mitigating the environmental quality of our cities. Two thirds of the world’s population still does not have access to sanitation, creating recurrent health and environmental disasters. The majority of these people are in tropical regions, mainly in sub-Saharan Africa, in countries whose economy does not allow the rapid development of large rainwater drainage networks and wastewater treatment plants. It is therefore necessary to innovate and change the urban water management model. Like international institutions (UNESCO, USAID, AFD, FFEM, etc.) and the pursuit of the SDGs for the Horizon 2030, the research arena is highly challenged to develop sustainable and cross-disciplinar solutions allowing changes in concepts regarding the perception of the usefulness of wastewaters and rainwaters for green production in cities. The opportunities for innovation are numerous, from process engineering to ecological engineering, from biogeochemists and microbiologists to creators of IoT and AI algorithms, from architects and urban planners to geographers.

This Special Issue titled “Waste Water Used for Green Production in Cities” aims to create opportunities for technological innovations and paradigm shifts to make rain waters and domestic wastewaters an economic and ecological asset for green production in the city, for food and human health, and for the poverty alleviation.

Contributions may focus on, but are not limited to, the following topics:

• waste water used and reuse, wash…
• waste water used and healthy;
• waste water used and agroecology, ecohydrology;
• waste water used and ICTs;
• waste water used and circular economy, bioeconomy;
• waste water used and green cities, soil and water concern
