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 scheme.

An irrigation scheme often draws water from the river and distributes it over the irrigated area. As a hydrological result it is found that: These may be called direct effects.

Effects on soil and water quality are indirect and complex, and subsequent impacts on natural, ecological and socio-economic conditions are intricate.

In some, but not all instances, water logging and soil salinization can result. However, irrigation can also be used, together with soil drainage, to overcome soil salinization by leaching excess salts from the vicinity of the root zone.

As a hydrological result it is found that the level of the water descends. Irrigation projects can have large benefits, but the negative side effects are often overlooked. As a result of this massive diversion of freshwater, lakes, rivers, and creeks are running dry, severely altering or stressing surrounding ecosystems, and contributing to the extinction of many aquatic species.

Forannual average soil loss by sheet, rill and wind erosion on non-federal US land was estimated to be On uncultivated cropland, the recent average total soil loss has been 2. Although reduction of methane emissions would have a rapid effect on warming, the expected effect would be small.

Management practices that can mitigate GHG emissions from production of livestock and feed have been identified. There are several published estimates of water use associated with livestock and meat production, but the amount of water use assignable to such production is seldom estimated.Peat Bogs.

A peat bog is a type of wetland whose soft, spongy ground is composed largely of living and decaying Sphagnum moss. Decayed, compacted moss is known as peat, which can be harvested to use for fuel or as a soil additive. Peat bogs are found throughout the world where cool temperatures and adequate rainfall prevail.

Paul Kingsnorth is a writer and poet living in Cumbria, England. He is the author of several books, including the poetry collection Kidland and his fictional debut The Wake, winner of the Gordon Burn Prize and the Bookseller Book of the Year Award.

Kingsnorth is the cofounder and director of the Dark Mountain Project, a network of writers, artists, and thinkers. Peat Bogs Peat is a partially decayed organic matter laid down in anaerobic, or lacking oxygen, conditions in wetlands.

Peat forms when plant material, usually in marshy areas, is inhibited from decaying fully by acidic conditions. Peat bog is raised above the mineral groundwater table and thus supplied directly by precipitation (Goode & Ratcliffe, ).

Peat is a soil that is made up of the partially decomposed remains of dead plants which have accumulated on top of each other in waterlogged places for thousands of years/5(1). Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments and ecosystems, biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse.

The Industrial Revolution was the transition to new manufacturing processes in the period from about to sometime between and This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power, the development of machine tools and the rise of the factory system.
