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."
Desertification has also affected North Africa, which includes Egypt, Libya, Algeria, Tunisia, and Morocco, as a result of climate change, overgrazing, and unsustainable agricultural practices. Food and water shortages, population displacement, and biodiversity loss are all repercussions of desertification in these places, underscoring the ...
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.
However, those quantitative analyses published since 1980 have differed in their estimates of "forest cover", ranging from <1% to 32% of the total land area, with most reporting very low estimates, such as one or two percent. [8] The most-recent study, published in the journal Forests in 2021, found "a 35% increase [in tree cover] from 2002 to ...
Deforestation in British Columbia has resulted in a net loss of 1.06 million hectares (2.6 million acres) of tree cover between the years 2000 and 2020. [104] More traditional losses have been exacerbated by increased threats from climate change driven fires, increased human activity, and invasive species.
It has been estimated that between 50% and 75% of states in Nigeria, including Bauchi, Borno, Gombe, Jigawa, Kano, Katsina, Kebbi, Sokoto, Yobe, and Zamfara, are affected to varying degrees by desertification. There are 15 desertification frontline states in Nigeria out of the total of 36 states and the Federal Capital Territory.
Over the period 1961–2013, the annual area of drylands in drought has increased, on average by slightly more than 1% per year, with large inter-annual variability. In 2015, about 500 (380–620) million people lived within areas which experienced desertification between the year 1980s and 2000s. The highest numbers of people affected are in ...
The Aralkum Desert (Uzbek: Orolqum choʻli, Оролқум чўли, Kazakh: Аралқұм шөлі, Russian: Пустыня Аралкум) is a desert that has appeared since 1960 on the seabed once occupied by the Aral Sea. [1] It lies to the south and east of what remains of the Eastern Basin Aral Sea in Uzbekistan and Kazakhstan. It is ...
