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.
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.
Much of the soil has rocks or clay from volcanic activity. Other causes include erosion, desertification, and deforestation. Another source of soil degradation is the improper management of waste, lack of facilities and techniques to handle waste lead to the dumping of waste in soil, therefore causes soil degradation by process such as leaching.
Other dryland regions have also experienced desertification. People living in already degraded or desertified areas are increasingly negatively affected by climate change (high confidence)." [8] Additionally, it is reported that 74% of the poor are directly affected by land degradation globally. [16]
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 ...
Last year, the World Bank approved a $73 million grant to help the Congolese government study the dam’s environmental and social impact. The dam, known as Inga III, would produce an enormous amount of energy in a country where there is almost none. But environmental experts say mining companies and aluminum smelters would be the main ...
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]
