Capture and retain heavy rainfall in Jordan

The Middle East is particularly affected by climate change effects and extreme weather events, such as droughts and heavy rainfall. In Jordan, repeated heavy rainfall events in recent years have led to flash floods with enormous damages. Minimizing such damages, but also maximizing the benefits of heavy rainfall via improved water retention in one of the most water-scarce countries in the world, is the research topic of CapTain Rain.

The project “CapTain Rain – Capture and retain heavy rainfalls in Jordan” is funded by the German Federal Ministry of Education and Research (BMBF) as part of the funding measure “CLIENT II – International Partnerships for Sustainable Innovation” in the context of the framework program “Research for Sustainable Development” (FONA). If you would like to learn more about the funding measure, watch the video of the CLIENT II YouTube channel with a short portrait of ongoing research projects in the MENA region.
