In this webinar, held on April 16, 2015, Frank van Weert (Wetlands International) discusses constructed wetlands: what are they? How can they delay drainage, retain, infiltrate and in particular purify water? In addition, various bio-chemical processes are related to these kind of wetlands. How do you operate them and which costs are associated with it? Frank also focusses on both the co-benefits of constructed wetlands – like biodiversity improvement and the beautification of the landscape – and the potential negative side effects.
Also in this webinar, Martin Onneweer (RAIN Foundation) discusses the 3R (Recharge, Retention and Reuse) from a Landscape point of view. The 3R approach has the ability to make a difference by making optimal use of the ground- and rainwater available in a particular area. By improving local water management practices for multiple purposes, people are given the means and confidence to increase their food security and improve their livelihoods.
