Water Resources and Impact of Climate Change
On average, surface water in Peru is abundant. Nevertheless, it is unequally distributed in space and time. Especially the coastal area, where the country's major cities are located and two thirds of the population live, is very dry. Lima with 8 million people, is the world's second largest city located on a desert (after Cairo).
Peru contains over two-thirds of all tropical glaciers which provide important water sources for the dry western half of the country. These glaciers are rapidly melting as a result of climate change, making the flow of rivers more irregular, leading to more droughts and floods. A report by a team from the World Bank published in June 2007 in the bulletin of the American Geophysical Union (AGU) predicts that many of the lower glaciers in the Andes will be gone in the next decade or so, and that glacial runoff may dry up altogether within 20 years. The last comprehensive satellite survey by Peru's National Environmental Council, carried out in 1997, found that the area covered by glaciers had shrunk by 22% since the early 1960s. Partial surveys by geologists suggest that the rate at which the glaciers are melting has speeded up over the past decade.
For example, the Quelccaya Glacier, the largest ice cap in the Peruvian Andes, has shrunk by 30% in the last 33 years. The streams fed by the glacier provide water to irrigation canals built by the Incas and, further downstream, for the city of Lima.

Famous quotes containing the words water, resources, impact, climate and/or change:
“In full view of his television audience, he preached a new religion—or a new form of Christianity—based on faith in financial miracles and in a Heaven here on earth with a water slide and luxury hotels. It was a religion of celebrity and showmanship and fun, which made a mockery of all puritanical standards and all canons of good taste. Its standard was excess, and its doctrines were tolerance and freedom from accountability.”
—New Yorker (April 23, 1990)
“But, with whatever exception, it is still true that tradition characterizes the preaching of this country; that it comes out of the memory, and not out of the soul; that it aims at what is usual, and not at what is necessary and eternal; that thus historical Christianity destroys the power of preaching, by withdrawing it from the exploration of the moral nature of man; where the sublime is, where are the resources of astonishment and power.”
—Ralph Waldo Emerson (1803–1882)
“As in political revolutions, so in paradigm choice—there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.”
—Thomas S. Kuhn (b. 1922)
“The climate has been described as “ten months winter and two months mighty late in the fall.””
—Administration in the State of Colo, U.S. public relief program (1935-1943)
“Indeed, I thought, slipping the silver into my purse ... what a change of temper a fixed income will bring about. No force in the world can take from me my five hundred pounds. Food, house and clothing are mine for ever. Therefore not merely do effort and labour cease, but also hatred and bitterness. I need not hate any man; he cannot hurt me. I need not flatter any man; he has nothing to give me.”
—Virginia Woolf (1882–1941)
