Farmer coaxes forest from the desert in Burkina Faso

OUAHIGOUYA, Burkina Faso (Reuters) - Yacouba Sawadogo murmurs advice to his sons as they press a sapling into the red earth using a centuries-old technique that he has adapted to conjure a forest from Burkina Faso’s rain-starved soil.






The farmer who is well into his 70s is hailed across his province as “the man who stopped the desert”. He won that title after tweaking a method of growing plants in pits to trap water - essential in the hardscrabble region fringing the Sahara.

After a terrible drought ravaged the Sahel in the 1970s and 1980s, many of Sawadogo’s neighbours abandoned their farms in northern Burkina Faso. But he stayed.


Pressures on land remain. Wind erosion, water shortages, rapid population growth and overgrazing cause around 470,000 hectares of land to degrade per year, data from the environment ministry show.

His use of so-called zai pits has in four decades created a 40-hectare oasis of thorny acacia, yellow-fruiting saba and other trees near his village in Yatenga province, bordering Mali.

“This forest that you see today was really a desert - there was not even the shade of a single tree here,” he says, sunlight dappling his face through the canopy above.

Farmers have dug small pits into the sunbaked soil for centuries and filled them with organic matter for their plants. Sawadogo experimented with digging wider and deeper pits and using stones.


When the rains arrive, his pits pit collect more water that feeds down to the seeds, increasing crop yields by up to 500%, according to the U.N. Environment Programme (UNEP).

The adoption of zai and similar soil and water conservation methods across the West African nation over the past 30 years has improved food security, groundwater levels, tree cover and biodiversity, according to a 2018 study in the journal Sustainability.

Sawadogo will keep planting. “If there are no trees and the land is not maintained, it would be a disaster.”

Zai Pits are a longstanding and well-documented tradition in the Sahel region, specifically in the north of Burkina Faso. Zai Pit System are “planting pockets” and “small water harvesting pits”. Seeds are sown into the pits after filling them with one to three handfuls of organic material such as manure, compost, or dry plant biomass. This leads to increased termite activity which, in turn, increases the rate of water infiltration when the rains come.

It’s labor-intensive but an effective weapon against desertification: the Zai system. This farming method is introduced in Ghana. Yields increase by 500 percent.

One of the major constraints to agriculture development in the Upper East Region of Ghana is land degradation. This is due to desertification and, according to Mr Asher Nkegbe, due to high population densities which make fallowing impossible and virtually all lands are cultivated continuously every year.
Mr Asher Nkegbe is the Regional Director of the Environmental Protection Agency (EPA). He introduces a new sustainable land and water management intervention in the region. This provides a window of opportunity for farmers to improve crop performance in this harsh and changing climate. The future seems brighter for the farmers and their families, says mr. Nkegbe.

Increase food production
Since the Regional Director introduced the Zai Concept, the crops of the farmers involved are doing better than before. It is expected that those who started the concept would harvest higher yields and be able to feed their households so as to attract more farmers to the new farming technology to increase food production and ensure food security in the region.
The system originates from West-Africa. Farmers are empowered with the necessary skills and capacity of digging planting pits in crusted soils which used to produce high runoff.
The zai pits have a diameter of 15 to 30 cm and a depth of 10 to 15 cm to collect rainfall and runoff. This means that more water infiltrates so that water will be available to plant roots. Farmers put a handful of organic matter in each pit (ranging from about 300 gram per pit).

Desertification
The Zai concept captures rainfall and runoffs, promotes the efficient use of limited quantities of organic matter and ensures the concentration of water and soil fertility at the beginning of the rainy season.
The use of the Zai method increases the amount of water stored in the soil profile by trapping rain water. It retains moisture in-situ and holds water long enough to allow it to infiltrate.
Pits are sometimes dug during the dry season, which alleviates the labour burden for land preparation at the onset of the rains. Besides, Zai improves soil fertility in completely barren soils where nothing could grow before. They also protect seeds and organic matter against being washed away, in addition to conserving nutrients.
Even though they are labour intensive, experts say they increase yields by up to 500 percent if properly executed. Zaï technology also reactivates biological activities in the soil and eventually leads to an improvement in soil structure. This eventually leads to less desertification.
Farmers across the Upper East Region of Uganda adopt the Zai technology. Some 150 farmers expect to get higher yields than before. It is hoped that in the next farming seasons many farmers would adopt the concept to help contribute to food security in the Region.

Lol, crazy coincidence

I'm reading a novel right now where climate apocalypse has happened (plus a pandemic impacting men has basically flipped gender roles) and some sort of witches travel to the past to find techniques and knowledge that might help them in the future

One of the most useful they found for their survival is the zai
