The environmental impact of irrigation includes the changes in quantity and quality of soil and water as a result of irrigation and the ensuing effects on natural and social conditions at the tail-end and downstream of the irrigation scheme. The impacts stem from the changed hydrological conditions owing to the installation and operation of the ...
Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments [14] and to ecosystems, biodiversity, and natural resources [15] caused directly or indirectly by humans.
Resource depletion — Exploitation of natural resources • Overdrafting (groundwater) • Overexploitation Consumerism — Consumer capitalism • Planned obsolescence • Over-consumption Fishing — Blast fishing • Bottom trawling • Cyanide fishing • Ghost nets • Illegal, unreported and unregulated fishing • Overfishing • Shark ...
Water pollution (or aquatic pollution) is the contamination of water bodies, with a negative impact on their uses. [1]: 6 It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater.
The human population on Earth is expanding rapidly, which together with even more rapid economic growth is the main cause of the degradation of the environment. Humanity's appetite for resources is disrupting the environment's natural equilibrium.
Environmental policy is the commitment of an organization or government to the laws, regulations, and other policy mechanisms concerning environmental issues.These issues generally include air and water pollution, waste management, ecosystem management, maintenance of biodiversity, the management of natural resources, wildlife and endangered species.

[4] [5] Management of the global atmosphere now involves assessment of all aspects of the carbon cycle to identify opportunities to address human-induced climate change and this has become a major focus of scientific research because of the potential catastrophic effects on biodiversity and human communities. Other human impacts on the ...
The human-caused changes to the water cycle will increase hydrologic variability and therefore have a profound impact on the water sector and investment decisions. [9] They will affect water availability (water resources), water supply, water demand, water security and water allocation at regional, basin, and local levels. [9]
