18th NERPS Webinar: Integrated Water Solutions for Cities Resilient to Global Climate Change

September 8, 2022 (Thursday 6:00-7:00 PM JST)

About the Webinar

Long periods of drought can create water supply crises, affecting citizens’ lives extensively. Traditional water supply solutions based on centralized single-source water systems have been proven ineffective in a country like Brazil, where the problem has recurrently impacted more than 48% of its municipalities. Thus, current public supply systems must be restructured by accommodating various modern concepts of water source diversification. In this presentation, we will first summarize the reasons for the water crises identified by a profound reflection conducted by the SACRE+SPRINT Projects (São Paulo Research Foundation’s five-year-grant proc. 2022/00652-7) that involve the participation of multiple universities in Japan, Canada, and Brazil. Then, we propose a hybrid hydro-economic approach as a solution to reduce water vulnerability, based on (i) water resource allocation and conjunctive surface and groundwater use, (ii) low-cost groundwater treatment (reactive barriers and phytoremediation), (iii) managed aquifer recharge (MAR), (iv) riverbank filtration systems, as well as (v) socio-economic analysis on the water resources management policies, including the payment for water services of the various components of the hydrological cycle.

About the NERPS Webinar Series

The Network for Education and Research on Peace and Sustainability (NERPS) at Hiroshima University in Japan is hosting a series of webinars on the relationship between peace and sustainability in the context of environmental, socio-political, economic, and technological transformations. This series is situated within the urgent need to deal with the implications of global change, including the COVID-19 pandemic, for peace and sustainability. The webinar sessions serve as a platform for rethinking and updating the current discourse on peace and sustainability amidst these global challenges and transformations. Leading experts will discuss the role of resources, digital technologies, migration, governance, and education in peacebuilding, conflict mitigation, humanitarian aid, and capacity-building, among other components that contribute to the achievement of the Sustainability Development Goals, particularly that of Goal 16 on Peace, Justice and Strong Institutions.
