Green Water Credits can be seen as an investment mechanism for upstream farmers to practice soil and water management activities that generate benefits for downstream water users, which are currently unrecognized and unrewarded. FutureWater coordinated and carried out the biophysical assessment that quantified the impact of Green Water Credits practices on the green and blue water and sediment fluxes in the Upper Tana basin. The analysis lead to identification of potential target areas for GWC pilot operation on biophysical grounds.

Green Water Credits can be seen as an investment mechanism for upstream farmers to practice soil and water management activities that generate benefits for downstream water users, which are currently unrecognized and unrewarded. This initiative is driven by economic, environmental and social benefits. The implementation of GWC has the potential of enhancing overall water management by reducing damaging runoff, increase groundwater recharge, simulate a more reliable flow regime, and reduce harmful sedimentation of reservoirs.

Green Water Credits: the concept.

FutureWater coordinated and carried out the biophysical assessment that quantifies the impact of Green Water Credits practices on the green and blue water and sediment fluxes in the Upper Tana basin. The analysis leads to identification of potential target areas for GWC pilot operation on biophysical grounds. This required a distributed modeling approach (SWAT) accounting for the heterogeneities in the basin in terms of precipitation regime, topography, soil characteristics and land use. The developed tool quantifies the benefits of the management practices on erosion reduction and green and blue water flows in the basin.
