Land surface effects on climate

Land surface effects on climate are wide-ranging and vary by region. Deforestation and exploitation of

effects of global warming.[1][2][3]

Deforestation effects

Deforestation by region

Major land surface changes affecting climate include

grasslands and xeric woodlands by overgrazing, or lack of grazing. These changes in the natural landscape reduce evapotranspiration, and thus water vapor, in the atmosphere, limiting clouds and precipitation. It has been proposed, in the journal Atmospheric Chemistry and Physics, that evaporation rates from forested areas may exceed that of the oceans, creating zones of low pressure, which enhance the development of storms and rainfall through atmospheric moisture recycling.[9] The American Institute of Biological Sciences published a similar paper in support of this concept in 2009.[10] In addition, with deforestation and/or destruction of grasslands, the amount of dew harvested (or condensed) by plants is greatly diminished.[11][12][13] All of this contributes to desertification
in these regions.

25-50% of the rainfall in the Amazon basin comes from the forest, and if deforestation reaches 30-40% most of the Amazon basin will enter a permanent dry climate.[14] In another article published by Nature, it points out that tropical deforestation can lead to large reductions in observed precipitation.[15]

This concept of land-atmosphere feedback is common among permaculturists, such as Masanobu Fukuoka, who, in his book, The One Straw Revolution, said "rain comes from the ground, not the sky."[16][17]

Deforestation, and conversion of grasslands to desert, may also lead to cooling of the regional climate. This is because of the albedo effect (sunlight reflected by bare ground) during the day, and rapid radiation of heat into space at night, due to the lack of vegetation and atmospheric moisture.[18]

Reforestation, conservation grazing, holistic land management, and, in drylands,

water harvesting and keyline design, are examples of methods that might help prevent or lessen these drying effects.[19]

Mountain meteorological effects

Orographic lift

Orographic lift occurs when an

Rain shadow

Main article: Rain shadow

A rain shadow is a dry area on the leeward side of a mountainous area (away from the wind). The mountains block the passage of rain-producing weather systems and cast a "shadow" of dryness behind them. Wind and moist air is drawn by the prevailing winds towards the top of the mountains, where it condenses and precipitates before it crosses the top. In an effect opposite that of orographic lift, the air, without much moisture left, advances behind the mountains creating a drier side called the "rain shadow".[citation needed]

Foehn wind

Main article: Foehn wind

A föhn or foehn is a type of dry, warm, down-slope wind that occurs in the

lee (downwind side) of a mountain range.[citation needed

It is a
