In many areas in the world people have to deal with water scarcity even there’s enough rainfall and run-off water on an annual basis. Most water simply disappears because of floods and evaporation. Water buffering allows us to manage natural recharge and to retain water longer. The approach of recharging, retaining and reusing water (3R) stores it in the landscape, securing water for dry periods.
Buffering is often associated with mega-dams and enormous surface reservoirs, but storing water in the ground with 3R has much more advantages. Spoiler: it has a lot to do with securing water.
– 3R solutions can be applied almost anywhere in the world, from rural areas to flat lowlands. This means: more people are secured with water.
– Storage in the soil profile doesn’t lose water to evaporation. Again: more people are secured with water.
– Buffering water in the soil can be done without being affected by sedimentation.
– The small 3R systems don’t disrupt life in the area. Instead they bring value to the livelihoods.
Yes, water buffering plays an important part for more sustainable land and water management, which contributes to food security, income generation and climactic change adaption. This publication presents several studies on water buffering, illustrated by cases across the globe. Also: don’t miss out on the DIY method. Questions? Contact RAIN.
