Apr 7, 2024 · 1. Date Palm ( Phoenix dactylifera) The Date Palm ( Phoenix dactylifera) is a majestic and iconic plant species that thrives in the harsh conditions of arid regions, notably the Sahara Desert. This palm is highly revered not only for its aesthetic appeal, creating lush oases amidst barren landscapes, but also for its invaluable fruit production ...

In 2018, a nursery was established to reforest the area. During the following four years, the community planted 360,000 saplings, becoming stewards to a flourishing area of vegetation that stretches over 100 hectares (250 acres). 18 Now, the first trees planted are providing shade in which families can grow other crops.

Biodiversity loss is a major global concern . Because of its spatial ambition, the GGW has a role to play in reversing the trend on the scale of the African continent. At the local level, Sahelian populations are highly dependent on woody biodiversity to provide them with ecosystem services to meet their daily needs for food, health, fuelwood, cons...
The characteristics of the root system are equally spectacular. It develops very quickly, even during the first dry season after transplanting the young plant into the ground, while at the same time its aerial parts develop much more slowly. Root morphology has a dual system that is very structurally efficient: lateral roots grow near the soil surf...
At the species level, we are able to identify the right balance between the practice of old and proven techniques (zai, half-moon ), and the contributions of modern science (new varieties better adapted to drought; pre-inoculation of plants with mycorrhizal fungi , beneficial soil microorganisms that improve mineral nutrition and water status of pl...
The Sahel area is subject to severe hydroclimatic and anthropogenic constraints that make it highly vulnerable (soil erosion, desertification, biodiversity loss, malnutrition).Subjected to unprecedented population growth and the negative consequences of ongoing climate change, its vulnerability is bound to increase in the future.At the same time, its capacity for resilience is strong, provided that appropriate actions are taken. State-of-the-art methodologies and modern research tools demonstrate this potential, particular...The Great Green Wall and its various actions are an effective lever to improve the situation in the Sahel, provided, however, that all stakeholders, including researchers, managers and local benefi...Sep 18, 2019 · The Great Green Wall — a project that aims to plant a vast wall of trees across North Africa — cannot prevent an expansion of the Sahara. Nor can planting trees in semi-arid regions in general increase rainfall. The Sahara is a desert because it receives negligible rainfall. It receives little rainfall because of where it’s located.
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 Sahel Acacia Savannas bioregion, located in the Sub-Saharan Afrotropics subrealm, consists almost entirely of one ecoregion—Sahelian Acacia Savanna [53]—that spans across the width of the continent from northern Senegal and Mauritania on the Atlantic coast to Sudan and Eritrea on the Red Sea. Commonly referred to as the ‘Sahel ...
