Soil degradation examples contain a decline in soil fertility, adverse changes in alkalinity, acidity or salinity, extreme flooding, use of toxic soil pollutants, erosion, and deterioration of the soil's structural condition. 4. Question. Land and soil degradation. Land degradation is defined as the temporary or permanent decline in the productive capacity of the land, and the diminution of the productive potential, including its major land uses (e.g., rain-fed arable, irrigation, forests), its farming systems (e.g., smallholder subsistence), and its value as an economic resource. Climate change is likely to exacerbate Nigeria's current vulnerability to weather variability, leading to a longer- term reduction in . But, addressing land degradation can include large scale projects across large areas of continents, countries and regions.

The causes of land degradation can be divided into natural hazards, direct causes, and underlying causes. Land degradation has accelerated during the 20 th and 21 st centuries due to increasing and combined pressures of agricultural and livestock production (over-cultivation, overgrazing, forest conversion), urbanization, deforestation and extreme weather events such as droughts and coastal surges, which salinate land. It affects a large number of people over a significant proportion of the earth's surface. Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. Final Government Distribution Chapter 4: IPCC SRCCL Subject to Copy-editing 4-5 Total pages: 186 1 habitats, and infrastructure through increased rates of land degradation (high confidence) and from 2 new degradation patterns (low evidence, high agreement). Pesticides often contain toxic elements that can pollute the soil. Preserving and improving the quality of land is an important component of sustainable development, while at the same time it contributes to adaptation and mitigating the climate chan. 0. 304. There are many definitions of land degradation but all share the idea that detrimental changes to the condition of land have occurred because of the many ways land has been developed and used. Nine Main Causes of Land Degradation are as follows: 1. Land degradation status. Chemical degradation includes increasing acidity . Solution.
