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.Culture and Climate Change: Scenarios focuses on the imagining and representation of climate change scenarios.
The use of scenarios in the context of climate change is widespread - in business, in climate policy, climate modelling and climate adaptation planning. This started with a tweet.
I’m embarrassed how often that happens. Frustrated by a sense of global mispriorities, I blurted out some snarky and mildly regrettable tweets on the lack of attention to climate change in the tech industry (Twitter being a sublime medium for the snarky and regrettable).
Climate change is the problem of our time, it’s everyone’s problem, and most of our problem.
Attention has begun to shift from local, short-term seasonal patterns of temperature, rainfall, other elements of the weather, toward longer-term trends that can affect the entire Earth, se long-term (typically year) weather trends are called "climate.".
