In this webinar 3 experts shared their experiences from the field, focusing on their activities in Kenya. All experts present cases related to the 3R approach. 3R is a collection of techniques and management strategies in order to retain water above and in the soil, recharge groundwater, and reuse water. The approach focuses on locally applicable, adequate and sustainable techniques.
At the core of the 3R concept is the buffer function that groundwater provides – allowing one to deal with peaks and lows in water access and the increasing variability that many areas are expected to experience with climate change. The primary objective is to buffer water during the dry periods in water scarce areas, extending the temporal availability of the water within a basin. Examples of 3R techniques include rooftop harvesting, sand dams, river bank infiltration, subsurface dams, dune infiltration, retention basins, contour bounds.
This webinar provided the participants insights on the practical implementation of 3R. The presentations can be downloaded by clicking on them.
