Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
The United Nations estimate that about 30% of land is degraded worldwide, and about 3.2 billion people reside in these degrading areas, giving a high rate of environmental pollution. [2] Land degradation reduces agricultural productivity, leads to biodiversity loss, and can reduce food security as well as water security.
Pollution is the introduction of contaminants into the natural environment that cause adverse change. [1] Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring ...
A study from 2020 by the International Land Coalition, together with Oxfam and World Inequality Lab, found that 1% of land owners manage 70% of the world's farmland. The highest discrepancy can be found in Latin America, where the poorest 50% own just 1% of the land. Small landowners, as individuals or families, tend to be more cautious in land ...
Air pollution caused by agriculture through land use changes and animal agriculture practices have an outsized impact on climate change. Addressing these concerns was a central part of the IPCC Special Report on Climate Change and Land [3] as well as in the 2024 UNEP Actions on Air Quality report. [4]
Groundwater reserves will be depleted, and the remaining water has a greater chance of being of poor quality from saline or contaminants on the land surface. [24] Climate change is resulting into a very high rate of land degradation causing enhanced desertification and nutrient deficient soils. The menace of land degradation is increasing by ...
At some point in the mid-1980s, a pony-tailed upstate New York environmental activist named Jay Westerveld picked up a card in a South Pacific hotel room and read the following: "Save Our Planet ...
Environmental modelling indicates that globally over 60% of global agricultural land (~24.5 million km²) is "at risk of pesticide pollution by more than one active ingredient", and that over 30% is at "high risk" of which a third are in high-biodiversity regions.
