Pakistan’s population of nearly 181 million is growing at 2% per year; this population explosion has resulted in the country meeting the international definition of water stress—water availability in Pakistan has plummeted from about 5,000 cubic meters per capita in the early 1950s to less than 1,100 m3 per capita in 2011.
This ominous, mounting water paucity impairs the lives of Pakistan’s rural women, who bear the arduous responsibility of collecting and providing water for their households. The absence of a safe water supply at or near their homes—and the resulting need to walk up to 4 km or more to get water each day—has aggravated the burden of women’s duties in many ways, making them vulnerable in terms of both their health and personal safety.
Rural women are the worst victims of water scarcity; however, in some communities, evidence indicates that women are emerging as a “herald of change.”
All climate negotiations have been based on staying below 2°C above pre-industrial temperatures. Yet it looks increasingly unlikely that that will be possible. A new report, Turn Down the Heat: Why a 4°C Warmer World Must be Avoided, suggests that there is a 40 percent chance that we will reach 4°C by 2100 even if we stick to the agreed emission reduction commitments.
What does water look like in a 4°C world?
Put simply: it's complex. Water is a complicated system and one of the major impacts of climate change is the effect on the hydrological (water) cycle. These impacts will coincide with an unprecedented increase in demand for water because of population and economic growth.
They both hold the potential to help meet the needs of the poor and end poverty. New ideas and innovative solutions are critical to address the 2.5 billion people who lack access to proper sanitation. Lack of access to clean water and sanitation kills more than 4,000 children a day and a lack of sanitation results in billions of dollars in economic losses to developing countries. Now that more people have access to a mobile phone than to a toilet or latrine, it’s time to leverage technology to help reach development goals.
“Superstorm” Sandy passed through the northeast United States earlier this week. High winds and heavy rains caused considerable damage, particularly in New Jersey and New York. High winds damaged buildings and knocked down trees and branches. Falling trees and branches caused more damage, including falling on electrical and telephone wires, breaking them and causing widespread power outages. Further, the winds north of the storm’s center pushed already high tides into repeated surges, some as much as 4.5 m (over 13 feet) above normal high tide. Coastal areas, including parts of Manhattan, were submerged; road and subway tunnels filled with water. Heavy rains caused additional flooding along rivers and coastlines.
