e. Land degradation is a process in which the value of a biophysical or biochemical environment is affected by a combination of natural or human-induced processes acting upon the land. [1][2] It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable. [3] Natural hazards are excluded as a cause; however ...
Environmental impact of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by chemicals emitted from mining processes. These processes also affect the atmosphere through carbon ...
The exploitation of natural resources describes using natural resources, often non-renewable or limited, for economic growth [1] or development. [2] Environmental degradation, human insecurity, and social conflict frequently accompany natural resource exploitation. The impacts of the depletion of natural resources include the decline of ...
Economic valuation of land degradation. Economics of land degradation look at the true costs of degrading land and land-based ecosystems as well as the benefits that derive from sustainable management of land and land-based ecosystems. The ELD Initiative provides ground-truthed tools and assessments that allow other parties to undertake cost ...
Environmental degradation is one of the ten threats officially cautioned by the High-level Panel on Threats, Challenges and Change of the United Nations. The United Nations International Strategy for Disaster Reduction defines environmental degradation as "the reduction of the capacity of the environment to meet social and ecological objectives ...
Overexploitation. Atlantic cod stocks were severely overexploited in the 1970s and 1980s, leading to their abrupt collapse in 1992. [ 1 ] Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. [ 2 ] Continued overexploitation can lead to the destruction of the resource, as it ...
The former type of conflict gives rise to environmentalism of the poor, in which environmental defenders protect their land from degradation by industrial economic forces. Environmentalist conflicts tend to be intermodal conflicts in which peasant or agricultural land uses are in conflict with industrial uses (such as mining).
Soil retrogression and degradation are two regressive evolution processes associated with the loss of equilibrium of a stable soil. Retrogression is primarily due to soil erosion and corresponds to a phenomenon where succession reverts the land to its natural physical state. Degradation is an evolution, different from natural evolution, related ...
