Afghanistan
Located in central Asia, with no maritime borders, Afghanistan covers a land area of 251,772 sq. mi. (652,086 sq. km). The country's estimated population shrank by 3.5 million from 2007 to 2011, when the estimated population stood at 28.4 million with a population density of 111.8 people per sq. mi. (43.56 per sq. km). About 12 percent of the country is arable land, with 46 percent used as meadow or pasture. In addition, only three percent of the country is forested. Officially, some 80 percent of the population makes a living from agriculture.
The country has been at war since the late 1970s, and as a result there are numerous environmental problems facing Afghanistan, including unexploded ordnances and a poor infrastructure. Parts of Afghanistan have faced severe shortages of food, alleviated by foreign aid—initially from the Soviet Union, later from parts of the Islamic world, and then from Western governments that support the Afghan government of president Hamid Karzai. There have also been campaigns to eradicate the production of opium poppy and cannabis, with attempts to foster the planting of food crops instead.
Conflict and the Loss of Forests
The arid countryside and resulting low level of subsistence
agricultural production has been highlighted as a serious problem
that faces Afghanistan, with the rising global temperature likely to
lead to further declines in farming. Since fighting began in 1978,
Afghanistan has lost over 70 percent of its forests, leading to soil
erosion, a decline in soil fertility, and a rise in salinization. In
addition, there has been a dramatic fall in water tables, which has
affected electricity production, as 64 percent of electric power
comes from hydropower. The remaining 36 percent is derived from
fossil fuels. One important hydroelectric plant is located in Sarobi
on the Kabul River and provides much of the power for Kabul, the
capital and largest city. It was built in the 1950s with German
assistance. A drought from 1998 to 2001 led to power blackouts as
hydroelectric power production was badly affected. Prior to the use
of hydropower, there was heavy reliance on wind power, with
horizontal windmills installed on top of buildings between Herat in
the west and the Iranian frontier from as early as the 7th century
c.e. These windmills were primarily
used to grind grain.
The sulfur industry operates around the city of Maimana in the northwest part of the country, and a small oil industry exists near Herat. There is also a small solar installation near Kabul in the east.
Meteorological data is difficult to record with much accuracy in Afghanistan because of the dangers posed to continuous research in the country. However, in 2001, Afghanistan recorded the warmest winter on record, with crop production decreasing. The Afghan refugee crisis created by the war continues, with many people unable to subsist in their villages. Because the country is greatly underdeveloped, it has one of the lowest carbon dioxide emissions per capita in the world, with 0.2 metric tons per capita in 1990 falling to negligible levels in 1997, and now estimated at 0.03 metric tons per capita. Only Burundi, Chad, the Democratic Republic of Congo, and Mali record even lower levels. The Afghan government took part in the United Nations Framework Convention on Climate Change (UNFCCC) signed in Rio de Janeiro in May 1992, which took place less than a month after the overthrow of the pro-Russian president, Mohammad Najibullah. Under the Taliban government, there was little participation in international forums, and the government of president Hamid Karzai has not expressed an opinion on the Kyoto Protocol to the UNFCCC.
