regreening forces
with partners,
and livestock keepers

In Northern Tanzania, we partner with Trias and LEAD Foundation to breathe new life into Arusha and Manyara regions.

The regions are home to the farmers and pastoralists, who rely on agriculture and livestock for their livelihoods but face challenges due to drought and insufficient pasture.

Time for a change! That’s why we are restoring agricultural and communal grazing lands along the Lake Manyara – Lake Natron Wildlife Corridor together with LEAD Foundation, Trias and Member Based Organizations.

Our goal is to improve the lives of local communities while restoring nature through Rainwater Harvesting (RWH), Farmer Managed Natural Regeneration (FMNR) and Pastoralist Managed Natural Regeneration (PMNR). These methods are fast, cost-effective, and sustainable, allowing residents to rejuvenate their lands, benefiting water availability, soil health, crop yields, and livestock fodder. At a larger scale, regreening also has a cooling effect on the local climate.

We brought back 97 thousand trees with Treecovery

We bring back forgotten tree stumps by using a technique called Farmer Managed Natural Regeneration (FMNR), or – as we like to call it: Kisiki Hai. This is more effective than planting new trees!

By regenerating those trees, we are able to restore the degraded areas and make these areas green and cool again.

Bunds (or as we like to call them: “earth smiles”) are semi-circular shaped pits that capture rainwater.

They are dug in the project areas in Africa in order to capture rainwater that will otherwise get washed away over the dry, barren soil. By digging bunds, we can regreen a large area in a very short amount of time, benefiting biodiversity, nature, people and – eventually our climate.

Fanya Juu and Fanya Chini are rainwater harvesting techniques. Farmers dig trenches along the contours within their farmland to prevent erosion and to capture the valuable rainwater within their land.

One of the main advantages bringing back vegetation is that it creates more moisture into the air. Vegetation “transpires”: it releases moisture into the air which cools it down. On a large enough scale, this helps to create clouds and increases the chance of rain, especially at the beginning and end of the rainy season, helping to restore the water cycle.



Within our grass seed banks, Maasai women grow, harvest, and sell grass (hay) and seeds. They make an income by selling them on local markets or to organizations. The grass seed banks form an oasis of green in the barren surroundings, and the hay the women harvest is food for their livestock in dry seasons.

Selling the grasses and the grass seeds harvested from the grass seed banks  generates a source of income for the women who are managing the grass seed banks. This income serves as an alternative livelihood, making the women more independent.

In total 81 women are involved in these grass seed banks.

Water Bunds

Water bunds are semi-circular holes dug to open up the hard top layer of the soil.

The bunds slow down and capture rainwater running downhills, preventing erosion of fertile soil. The water balance in the soil restores, increasing the water availability for the seeds still present in the soil. These seeds now get the chance to sprout, which means: regreening! Within the Arusha project area, the Maasai community already dug 22,000 water bunds!

Pastoralist Managed Natural Regeneration (PMNR), or Kisiki Hai (‘living stump’ in Swahili), is a technique to regrow trees and support new, naturally occurring sprouts to grow big.

With the program local Maasai pastoralists and farmers are trained to apply the technique on their own land, allowing the regeneration of 32,000 trees.

Fanya Juu and Fanya Chini

Fanya Juu and Fanya Chini are rainwater harvesting techniques. Farmers dig contours within their farmland to prevent erosion and to capture the valuable rainwater within their land.

Fanya Chini means ‘ throw it downwards’ in Swahili. It prevents the rain from falling outside the farm from entering the farm, inhibiting erosion of fertile soil. Fanya Juu means ‘throw it upwards’, and prevents the rain falling within the farm to run off, increasing the water availability for the crops on the land. In the end, it helps the farmers to regreen their farms even more!

Capacity building

By training 100 facilitators (so-called ‘regreening’ champions), we can reach out to 1200 agro-pastoral households in the Arusha region.

These champions train their fellow community members on how to regenerate trees on their land. This way thousands of people are activated to regreen their own land, bringing back millions of trees in the Arusha region resulting in an increase in drought resilience, food production, and household income. The regreening champions are also trained in rainwater harvesting practices, helping them to regreen the land even further.

Building a Movement

For us it is not only important to train people how to regreen their land, but also find other ways to reach and inspire them. By building a real regreening movement we aim to reach and inspire millions of Maasai pastoralists and farmers.

Part of this regreening movement is our movie roadshow: a video-caravan going from village to village. The roadshow is a whole day event, filled with theatre, music, dance, and performances all about Kisiki Hai. When the evening falls, a large movie-theatre screen is set up, which shows the inspiring movie Kisiki Hai that is filmed entirely in Tanzania.

Contactless regreening

To spread the regreening movement even further, we’ve set up various approaches to reach and activate communities, without physically visiting them. This way we are able to inspire pastoralists and farmers in and outside of the Arusha region! 

Together with partners LEAD and Erbacher Foundation, we will offer a Regreening SMS-service. Pastoralists can subscribe to this service, which will send them a text message every week with tips and tricks on how to practice Kisiki Hai and Fanya Juu, and Fanya Chini.

Partner up Digital Regreening Platform


To truly understand how nature-based solutions transform entire landscapes, ecosystems and communities, you have to see it with your own eyes.

And that’s where we run into a problem: we can’t transport the entire world to our project areas. With this interactive experience, we found a solution. We decided to bring our regreening projects directly to you. Virtually, wherever you are. Come on in and experience the Water bund site and Treecovery farm!

Our mission

Our mission is to regreen African landscapes in the next 10 years, together with millions of farmers, and together with you.

If we want to cool down the planet in one decade, everyone needs to be in on the change. Through the power of media, communication, data, and the latest technology we can spread our message and scale up. We want to inspire, unite and empower an entire generation, growing a landscape restoration movement.
