For example, Europe on average imports over 50% of its food. Meanwhile, 44% of agricultural land is located in dry lands and it supplies 60% of the world's food production. Desertification is decreasing the amount of sustainable land for agricultural uses but demands are continuously growing.
Desertification in Africa is exacerbated by human factors such as deforestation, overgrazing, and unsustainable farming methods such as monoculture and excessive use of chemical fertilizers. For example, deforestation reduces the quantity of plants that may anchor soil and protect it from erosion, whereas overgrazing depletes vegetation and ...
Desert farming is the practice of developing agriculture in deserts. As agriculture depends upon irrigation and water supply, farming in arid regions where water is scarce is a challenge. However, desert farming has been practiced by humans for thousands of years. In the Negev, there is evidence to suggest agriculture as far back as 5000 BC. [1]
Consequently, deforestation, largely driven by human activities, has played a significant role in the desertification of Ghana. [4] Climate change is a significant contributor to desertification in Ghana. [19] The country is especially susceptible since it relies heavily on rain-fed agriculture and has inadequate capacity for mitigation and ...
Land degradation reduces agricultural productivity, leads to biodiversity loss, and can reduce food security as well as water security. [3] [1] It was estimated in 2007 that up to 40% of the world's agricultural land is seriously degraded, [4] with the United Nations estimating that the global economy could lose $23 trillion by 2050 through ...
Desertification is one of the issues of environmental concern in Nigeria, particularly the northern part of the country. According to UNEP [4] in 1993, Northern Nigeria has one of the highest rates of deforestation in the world at about 3.5%, caused by land degradation, increase in agricultural intensity, over-grazing of livestock, and demand for fuel by cutting down trees.
Satellite images reveal desert ruins — and lead to 4,000-year-old ‘walled oasis’ ... Between 2020 and 2023, experts explored the Khaybar Oasis, an ancient agricultural center, the study said ...
It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity and biodiversity of the land and is one cause of desertification and erosion.
