Biological Soil Crust (BSC), also known as biocrust is a living, thin layer of soil surface composed of communities of microorganisms such as cyanobacteria, algae, lichens, mosses, fungi, and other microbes, tightly bound with soil particles. These crusts play a vital ecological role in arid and semi-arid environments by stabilizing soil surfaces, reducing erosion, enhancing water retention, fixing atmospheric nitrogen, and facilitating seed germination. They improve soil fertility and structure by increasing organic matter and microbial diversity. Biocrusts are particularly important in fragile ecosystems where vegetation cover is sparse, acting as a protective layer that sustains soil health and biodiversity. However, they are highly sensitive to disturbance and take years or even decades to recover once damaged.

Combating Desertification in Africa : Zainer’s Contribution to SDG 15 (Life on Land)

Zainer is a low-cost machine for climate resilient agriculture in arid and semi-arid regions.

The Zainer is a vertical soil drill, mounted on a two wheeled cart and powered by a small 5hp petrol engine. Excavated soil is deposited on the down-stream side of the Zaï pit to make sure that run-off water from the field is directed into the pit for local infiltration. The design of the Zainer has been optimized for fuel efficiency and drilling speed to minimize the operational costs for the farmer.
Operating the Zainer can be comfortably done by both female and male farmers. Depending on the soil conditions, farmers are able to produce up to 17 Zaï plantholes per minute and 1 ha of land can be prepared within 5 days (compared to 300 hours of labor for manual Zaï). The drill bit can easily be replaced and be adapted to different soil conditions and desired plant hole dimensions.
Due to climate change, rainfall patterns in Africa have become less predictable. As a result, African farmers are experiencing production losses for their main rainfed crops. This climate instability, combined with increasing land degradation linked to desertification, poses a serious risk to food security and family incomes, particularly for smallholder farmers.
Indigenous conservation and regenerative agriculture practices can largely mitigate these risks and help combat desertification, but farmers consider these traditional practices too labor-intensive and economically unviable.
Affordable mechanization of climate-smart agricultural practices can overcome these drawbacks. An organization called Practica has therefore initiated the development of a simple tool to quickly and inexpensively produce small basins or pits for local rainwater retention. This tool is called "Zaïner," in reference to the traditional West African practice of creating small planting holes, called Zaï.
This innovative tool aims to strengthen the resilience of soils and farmers in the face of desertification and climate change.

The man who stopped the desert : Yacouba Sawadogo

“For turning barren land into forest and demonstrating how farmers can regenerate their soil with innovative use of indigenous and local knowledge.”

Yacouba Sawadogo (1946-2023) was known as “the man who stopped the desert”. Starting around 1980 during a phase of severe drought, he successfully created an almost 40-hectare forest on formerly barren and abandoned land. Today, it has more than 60 species of trees and bushes and is arguably one of the most diverse forests planted and managed by a farmer in the Sahel.

Sawadogo’s remarkable success builds on experimenting with traditional planting pits for soil, water and biomass retention, called “zaï” in the local language. He continued innovating the technique over the years, increasing crop yields and successfully planting trees. Despite facing resistance from locals in the beginning – Sawadogo was called a “madman” and saw his forest set on fire – he never considered giving up. Over time, people came to admire his work.

Always eager to share his knowledge, Sawadogo trained thousands of visitors from the region and beyond, and empowered farmers to regenerate their land. As a result, tens of thousands of hectares of degraded land have been restored to productivity in Burkina Faso and Niger. Those who adopt Sawadogo’s techniques often become food secure, as zaï help to conserve rainwater and improve soil fertility. Trees planted together with the crops serve to enrich the soil, produce fodder for livestock and create business opportunities like beekeeping. This helps farmers adapt to climate change, reduce rural poverty and prevent local resource and water-related conflicts.

Hello everyone!
What a pleasure to be part of this inspiring community!
I'm Dieudonne Ilboudo, a water and environment specialist currently working at the General Office of Agropastoral Development and Irrigation of the Ministry of Agriculture, Animals and Fisheries Resources of Burkina Faso.
My work focuses on sustainable water resource management, soil conservation, land reclamation, and environmental preservation. I have over four years of experience in community projects promoting climate change adaptation, integrated water resource management, and the development of rice-growing lowlands.
I recently led initiatives on the management of invasive aquatic plants, transforming them into valuable resources such as compost and biochar to support local agriculture and the circular economy. I am passionate about drought resilience (Zai and Half-Moon Techniques) and ethical, inclusive, and innovative approaches to natural resource governance, and I strive to integrate local knowledge and community participation into all aspects of my work.
I look forward to learning, collaborating, and contributing to this dynamic network !

On this AfricaDay, it is inspiring to see progress in strengthening water governance in one of Africa’s most fragile and vital regions.

A new Simplified Practical Guide has been introduced to help local communities around Lake Chad better understand and apply the principles of the Lake Chad Basin Water Charter. Developed by the Lake Chad Basin Commission and IUCN, with support from the Swiss Development Cooperation through the BRIDGE initiative, this guide aims to close the gap between complex policy frameworks and on-the-ground realities.

Lake Chad, which spans five countries and supports tens of millions of people, is under increasing pressure from climate change, population growth, and competing resource demands. Strengthening cooperation and clarity in managing this shared water resource is more urgent than ever.

The guide is designed for local officials, farmers, pastoralists, and fisherfolk, those whose daily lives are closely tied to the lake. By simplifying key principles of the Water Charter, it helps to promote inclusive decision-making, equitable access, and shared responsibility.

For those of us engaged in drought resilience, transboundary water governance, or sustainable land management this is a timely and practical resource worth exploring.

Happy Africa Day, 2025!

Hello, I hope you are well.
It is a pleasure for me to share with you the half-moon technique, a traditional method of water and soil conservation widely used in Burkina Faso, particularly in arid and semi-arid areas. It involves digging semicircular basins, generally 2 to 4 meters in diameter, with the open edge facing upslope. This technique captures and retains runoff water during the rainy season, promoting its infiltration into the soil and vegetation regeneration. It is particularly effective for restoring degraded land, combating erosion, and improving soil fertility. Used in agroforestry and agricultural fields, the half-moon plays a crucial role in helping rural communities adapt to climate change and promote sustainable agriculture in Burkina Faso.
