Agricultural Development and Ecosystem Crisis in the Sahel Region of Africa - Current Situation in the 2020s

In the 2020s, the Sahel region of Africa continues to face serious environmental challenges. The Sahel is a semi-arid zone stretching from Senegal to Chad, where excessive agricultural development is threatening ecosystems. In countries such as Niger, Mali, and Burkina Faso, rapid agricultural expansion is taking place. These countries primarily grow monoculture crops like maize and sorghum, leading to rapid soil degradation.

The soil in the Sahel is already fragile, and the pressure from agriculture is accelerating desertification. By the early 2020s, it was reported that approximately 700,000 hectares of land across the Sahel were affected by desertification annually. In Niger, about 40% of agricultural land is at risk of desertification, significantly impacting agricultural production.

Water scarcity is also worsening. Lake Chad has shrunk by more than 90% over the past 50 years, drastically reducing the water resources that local residents depend on. Overuse of groundwater is also a problem, particularly along the Niger River, where agricultural use is lowering the water table. This has led to the depletion of wells, threatening the livelihoods of local communities and leading to a food crisis due to water shortages.

Additionally, habitat destruction from agricultural development is leading to a loss of biodiversity. The Sahel is home to many wildlife species, including giraffes, ostriches, and African elephants, but these animals are facing extinction due to shrinking habitats. In protected areas in Burkina Faso and Mali, poaching has increased, and wildlife populations are rapidly declining.

To overcome this crisis, the introduction of sustainable agricultural techniques is urgently needed. Techniques such as drip irrigation and agroforestry, which balance efficient water use with soil conservation, are recommended. Reforestation activities and strengthening policies to prevent desertification are also necessary. International support is crucial, with funding and technical assistance needed to address climate change and protect the Sahel's ecosystems.
