Desertification in Africa is caused by both natural and man-made forces. Climate change, which has resulted in increased aridity and decreasing rainfall in many regions, and soil erosion, which happens naturally but can be exacerbated by human activity, are the principal natural elements that lead to desertification. [18]
Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."
The Human impact on the environment factor is mainly the disruption of the ecological system caused by poor land use and increasing pressure on the available resources by the growing population. [10] Precisely, there are four primary causes which are over-exploitation, over-grazing, deforestation and poor irrigation practices, influenced by ...
Essentially, human-induced desertification is a result of the exploitation of "non-ideal lands," excessive resource exploitation, unsustainable practices, and the failure to replace or allow adequate time for the natural regeneration of depleted resources. Human activities leading to desertification include:
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.
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 ...
The Qhapaq Ñan, often called the Andean Road System, is an impressive pre-Hispanic network of ancient roads that once converged on the Inca capital of Cusco.The Incas played a large part in its ...
The UNDP report on climate change in Yemen, desertification is a major environmental issue intensified by climate change and human activities. The country faces severe droughts, unpredictable rainfall, and higher temperatures, all contributing to the degradation of arid and semi-arid land that makes up over 90% of its territory.
