Side Event
FARMER AND PASTORALIST-CENTRIC SOLUTIONS TO MANAGING DROUGHTS AND SAFEGUARDING LIVELIHOODS
The goal is to highlight farmer- and pastoralist-centered solutions to better anticipate, manage, and mitigate the effects of droughts. The side event aims to share practical approaches that strengthen resilience, protect livelihoods, and support sustainable adaptation to climate change.
Innovative Drought Resilience efforts in Burkina Faso.
Global context
Soil and Water Conservation
The half-moon is a 4 m diameter, 0.15–0.25 m deep semicircular pit traced on contour, excavated with hand tools or traction. Spoil is layered upstream and as a ridge. Topsoil is replaced, mixed with 35 kg manure or compost.

How to make a half-moon?
Soil and Water Conservation
The half-moons are spaced 4 m apart in a staggered pattern, each unit occupying 32 m² with a usable area of 6.28 m². On 1 hectare, this configuration allows for approximately 299–300 half-moons. The alignment respects the natural contours of the land, ensuring optimal distribution for water capture and soil restoration.

Soil and Water Conservation
Zaï is a traditional Sahelian technique using small pits (20–30 cm wide, 10–20 cm deep) dug in the dry season and filled with organic matter. The pits attract termites, improve soil fertility, and capture rainfall, reducing runoff and evaporation while directing water and nutrients to crops on degraded lands.

Soil and Water Conservation
Stone bunds and clay earth dikes are constructed by aligning stones or compacted earth along contour lines. They slow runoff, promote infiltration, reduce erosion and retain sediments, thus improving the fertility, regeneration and productivity of degraded soils.

Bouli, les banquettes, Hedges live through plants and Runoff Water Collection Basin play an essential role in conserving water and stabilizing soils. They retain runoff, improve infiltration, reduce erosion, promote groundwater recharge and create fertile microenvironments, sustainably strengthening agricultural production and landscape resilience.

Innovation tool for drought resilient
The Zainer is a low-cost, fuel-efficient soil drill for arid and semi-arid regions. Powered by a 5hp engine, it rapidly creates Zaï pits while depositing soil downslope to capture runoff. Easy to operate for all farmers, it produces up to 17 pits per minute and prepares 1 hectare in five days (compared to 300 hours of labor for manual Zaï).
Recovery of degraded land, improvement of soil fertility and increase in agricultural yields

Local community ownership ensures commitment, improves maintenance of restoration works, and strengthens long-term impact by empowering residents to protect and manage their own landscapes
Local community ownership
Land regeneration restores soil fertility, increases vegetation cover, improves water retention, and boosts agricultural productivity for resilient livelihoods.
