The increase in desertification in these regions has degraded the land to such an extent where people can no longer productively farm and make a profit. This has negatively impacted the economy and increased poverty rates. [39] There is, however, increased global advocacy e.g. the UN SDG 15 [40] to combat desertification and restore affected lands.
Desertification has substantial economic consequences in Africa, particularly in places where agriculture and natural resource utilization are the predominant sources of revenue. Desertification reduces crop yields, causes food shortages, and increases poverty in impacted populations by destroying fertile land and water supplies.
Ninety percent of Africa's population requires wood to use as fuel for heating and cooking. As a result, forested areas are decreasing daily, as for example, in the region of equatorial evergreen forests. According to the United Nations Environment Programme, Africa's desertification rate is twice that of the world's. [4] Deforestation of ...
Livestock owned by farmers is also impacted. As per the World Health Organization's report in 2015, Ghana's climate change is anticipated to worsen pre-existing problems like food insecurity, poverty, and infectious and vector-borne illnesses. [24] Overgrazing is one of the main causes of Ghana's desertification. [25]
The direct causes of deforestation within the DRC are well understood and have been identified consistently by many sources. [2] [3] [9] The direct causes are as follows: 1) road infrastructure development, 2) slashing and burning the forests to transform forest land into agricultural land, 3) the collection of fuelwood and charcoal, and lastly 4) unregulated artisanal and small-scale logging.
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.
This has a profound ecological impact in that Colombia is extremely rich in biodiversity, with 10% of the world's species, making it the second most biologically diverse country on Earth. [ 151 ] In 2024, deforestation in Colombia's Amazon region has increased by 40% during the first quarter compared to the same period last year, according to a ...
The United Nations Convention to Combat Desertification in Those Countries Experiencing Serious Drought and/or Desertification, Particularly in Africa (UNCCD) is a Convention to combat desertification and mitigate the effects of drought through national action programs that incorporate long-term strategies supported by international cooperation and partnership arrangements.
