Aug 16, 2021 · These fertile lands, however, are becoming increasingly infertile because of drought, deforestation, and intense agriculture. In effect, the Sahara Desert is slowly expanding into the Sahel. The Sahel has a tropical climate. Summers are very hot. The maximum mean temperature in the summer can range from 33°C to 36°C.
2 days ago · The Sahara exhibits great climatic variability within its borders, with two major climatic regimes differentiating along a north-south axis: the desert’s northern latitudes are arid subtropical and have two rainy seasons, while the southern ones, although also arid, are more tropical and have only one rainy season.
Jan 3, 2022 · The southern edge of the Sahara is bordered by a semiarid zone called the Sahel (shown here in Mali). The “Great Green Wall” project aims to stop desertification by planting a massive line of...
The Sahel or Sahel Belt (from Arabic ساحل, sāḥil, shore, border or coast of the Sahara) is a semi-arid tropical savanna ecoregion in Africa, which forms the transitional zone between the Sahara Desert to the north and the more humid savanna belt to the south known as the Sudan (not to be confused with the country of the same name ).

The correlation reveals that the Sahel is not becoming a desert on a large scale, though localized land degradation could be occurring. An animation of the vegetation and rainfall records from 1998 to 2005 shows the dance of the seasons across the Sahel with plant growth moving north as rain falls over the region.
