Water bunds

Digging for regreening

01

Digging bunds

Why do we capture rainwater?

The warming of the earth and persistent droughts cause desertification and degradation of the land in many areas. The top layer of the soil is often really hard, inhibiting rainwater to infiltrate into the soil. The water is flowing to lower areas, washing away the upper layer of fertile soil. By opening up this hard top layer and retaining the rainwater, the water has time to infiltrate into the soil, enabling vegetation to grow!

Re-grow vegetation

How does this work?

By capturing rainwater with the help of bunds, it has more time to enter the soil. The water balance is restored, and more water is available for the seeds still present in the soil. These seeds now get the chance to sprout, which means: regreening! Sometimes we give the regreening process a little push, by sowing extra seeds within the bunds. This way the area can be restored even better!

Water bunds

Why do we dig semi-circular bunds?

The semi-circular shape of the bunds is an optimal balance between the amount of water captured and the labor requirements. The bunds are 2.5 meters long and 5 meters wide, which is about the size of an adult elephant! They are dug on slopes, with the ‘closed’ side of the bunds directing downhills. This way they can capture the water running downhills. The bunds do not only capture the rainwater, they also make sure that the water running downhills in between the bunds is slowed down. Now the water also has a chance to enter the soil in between the bunds.

Spreading of the green

How can the whole area be regreened?

Not only inside the bunds vegetation has grown back, the area surrounding the bunds also gets increasingly greener. Here’s a quick explanation of how this works: 

* Bunds prevent rainwater from washing away: this leaves more time for water to sink into the soil within the bund, but also in the area around;

* The vegetation becomes so large and extensive that it starts to spread and grow outside of the bunds; 

* The seeds of the vegetation inside the bunds spread out and start growing outside the bunds where they lead to even more regreening!

And look at the great result!

Buy your own bund!

And invest in a greener and cooler planet

Do you already know our Regreening platform? By buying bunds on this platform you ensure regreening and directly support an African farmer who digs the bunds. For this, you first create an account, after which you choose the number of bunds that you want to have dug. You even receive a photo of your unique bund and experience the regreening process!
