Abstract

Despite progress, the 2015 Millennium Development Goal on access to basic sanitation will likely not be met by all the world’s countries, and most of the countries that may not reach the target, are in Africa. Climate changes will increase precipitation variability and extreme events, with growing risks for vulnerable areas. The work investigates the water and renewable energy nexus in wastewater management for urban areas of water stressed river basins. In particular, it identifies strategies for the design and deployment of decentralized wastewater facilities, which can help to tackle the effects of climate changes and increasing population, preserving the water bodies. Results show that the integration of wastewater and renewable sources provides a: i) greater resilience of the water supply and energy system, ii) lower impact of intermittent renewable energy, iii) reduction in the cost of electricity, when compared to its real cost, iv) access to a wider range of external funds to cover the investment. Finally, it has been outlined how the concept under analysis can contribute to security, both domestic and cross-border, improving the political stability in the region.
