For example, temperature increase by 1.5–2.1 percent across the Nile Basin over the next 30–40 years could change the region from semi-arid to arid, significantly reducing the land usable for agriculture. In addition, changes in land use can increase demands on soil water and thereby increase aridity. [6]
Aridification is the process of a region becoming increasingly arid, or dry.It refers to long term change, [1] rather than seasonal variation. It is often measured as the reduction of average soil moisture content.
There is a significantly greater proportion of drylands in developing countries (72%), and the proportion increases with aridity: almost 100% of all hyper-arid lands are in the developing world. Nevertheless, the United States , Australia , and several countries in Southern Europe also contain significant dryland areas.
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 decline in prairie dogs has significantly impacted many of the other animals that reside in the shortgrass prairie, including the black-footed ferret, whose diet relies on prairie dogs. Other animals negatively affected by the decline of prairie dogs are the mountain plover, swift fox, ferruginous hawk and the burrowing owl.
Across Africa, aridity has led to a 12% plunge in GDP, partly driven by degradation of arable land. From 17% to 22% of current crop production is projected to be lost in sub-Saharan Africa by mid ...
