Land degradation and desertification threaten people’s livelihood on a global scale. Every year, 20 million hectares of fertile land become degraded and within the last 40 years, around one third of the total agricultural land on earth has become unproductive through degradation processes. [6]
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."
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
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.

By 2008, deforestation in Africa was estimated to be occurring at twice the world average rate, according to the United Nations Environment Programme (UNEP). [5] [6] [7] Some sources claim that deforestation has already wiped out roughly 90% of West Africa's original forests. [8] [9] Today, deforestation is accelerating in Central Africa. [10]
The federal environment agency UBA reported in March 2022 that Germany's greenhouse gas emissions increased by 4.5% in 2021 compared to 2020. [8] As of 2021 Germany is the 6th heaviest cumulative emitter at about 100 Gt. [9] In 2016, Germany's government committed to reduce greenhouse gas emissions by 80% to 95% by 2050. [10]
