Water themes and data — EEA
Clean fresh water is essential to life. Unfortunately, since the Industrial Revolution, most of Europe's rivers have been treated unwisely as a convenient way of transporting waste to the sea, affecting the biodiversity of thousands of kilometers of waterways, harming human health, and in the end polluting coastal and marine waters.

DROUGHT
The countries that make up two thirds of the world’s agricultural output are experiencing drought conditions. Whether you watch a video of the drought in China, Australia, Africa, South America, or the US, the scene will be the same: misery, ruined crop, and dying cattle.
China
The drought in Northern China, the worst in 50 years, is worsening, and summer harvest is now threatened. The area of affected crops has expanded to 161 million mu (was 141 million last week), and 4.37 million people and 2.1 million livestock are facing drinking water shortage. The scarcity of rain in some parts of the north and central provinces is the worst in recorded history.
The drought which started in November threatens over half the wheat crop in eight provinces - Hebei, Shanxi, Anhui, Jiangsu, Henan, Shandong, Shaanxi and Gansu.
Henan China's largest crop producing province, Henan, has issued the highest-level drought warning. Henan has received an average rainfall of 10.5 millimeters since November 2008, almost 80 percent less than in the same period in the previous years. The Henan drought, which began in November, is the most severe since 1951.
Anhui Province issued a red drought alert, with more than 60 percent of the crops north of the Huaihe River plagued by a major drought.
Shanxi Province was put on orange drought alert on Jan. 21, with one million people and 160,000 heads of livestock are facing water shortage.
Jiangsu province has already lost over one fifth of the wheat crops affected by drought. Local agricultural departments are diverting water from nearby rivers in an emergency effort to save the rest.
Hebei Over 100 million cubic meters of water has been channeled in from outside the province to fight Hebei’s drought.
Shaanxi 1.34 million acres of crops across the bone-dry Shanxi province are affected by the worsening drought.
Since last November, Shandong province has experienced 73 percent less rain than the same period in previous years, with little rainfall forecast for the future.
Relief efforts are under way. The Chinese government has allocated 86.7 billion yuan (about $12.69 billion) to drought-hit areas. Authorities have also resorted to cloud-seeding, and some areas received a sprinkling of rain after clouds were hit with 2,392 rockets and 409 cannon shells loaded with chemicals. However, there is a limit to what can be done in the face of such widespread water shortage.
As I have previously written, China is facing hyperinflation, and this record drought will make things worse. China produces 18% of the world's grain each year.
Australia has been experiencing an unrelenting drought since 2004, and 41 percent of Australia's agriculture continues to suffer from the worst drought in 117 years of record-keeping. The drought has been so severe that rivers stopped flowing, lakes turned toxic, and farmers abandoned their land in frustration:
A) The Murray River stopped flowing at its terminal point, and its mouth has closed up.
B) Australia’s lower lakes are evaporating, and they are now a meter (3.2 feet) below sea level. If these lakes evaporate any further, the soil and the mud system below the water is going to be exposed to the air. The mud will then acidify, releasing sulfuric acid and a whole range of heavy metals. After this occurs, those lower lake systems will essentially become a toxic swamp which will never be able to be recovered. The Australian government's only options to prevent this are to allow salt water in, creating a dead sea, or to pray for rain.

water scarcity
What is water scarcity? Imbalances between availability and demand, the degradation of groundwater and surface water quality, intersectoral competition, interregional and international conflicts, all contributes to water scarcity.
Scarcity often has its roots in water shortage, and it is in the arid and semiarid regions affected by droughts and wide climate variability, combined with population growth and economic development, that the problems of water scarcity are most acute

National Accounts of Well-being
What are National Accounts of Well-being and why do we need them?
nef has set out a radical proposal to guide the direction of modern societies and the lives of people who live in them. In contrast to the conventional narrow focus on economic indicators, it calls for governments to directly and regularly measure people’s subjective well-being: their experiences, feelings and perceptions of how their lives are going, as a new way of assessing societal progress.

China plans 59 reservoirs to collect meltwater
China is planning to build 59 reservoirs to collect water from its shrinking glaciers as the cost of climate change hits home in the world's most populous country.
The far western province of Xinjiang, home to many of the planet's highest peaks and widest ice fields, will carry out the 10-year engineering project, which aims to catch and store glacier run-off that might otherwise trickle away into the desert.
Behind the measure is a desire to adjust seasonal water levels and address longer-term concerns that downstream city residents will run out of drinking supplies once the glaciers in the Tian, Kunlun and Altai mountains disappear.
Anxiety has risen along with temperatures that are rapidly diminishing the ice fields. The 3,800-metre Urumqi No1 glacier, the first to be measured in China, has lost more than 20% of its volume since 1962, according to the Cold and Arid Regions Environmental and Engineering Research Institute (Careeri) in Lanzhou.
About 80% of the glaciers in the Tian (Heaven) range have declined, though increased precipitation has also led a small number to expand.
To deal with the consequences, Xinjiang will set aside 200m yuan (£20m) for each of the next three years. In the first phase, 29 reservoirs will be built with a combined capacity of 21.8 billion cubic metres of water, according to the Xinhua news agency.
Wang Shijiang, director of Xinjiang Water Resource Department, told the agency that the mountain reservoir system was designed to "intercept" meltwater so that it could be used more efficiently for irrigation and to adjust for seasonal variations in rainfall.
Xinjiang is particularly dependent on a steady supply of meltwater from glaciers, which act as solid reservoirs that store precipitation in the winter and release it in the summer.
Few city residents understand the problem because in recent years water supplies have surged thanks to the extra meltwater and increased rainfall. The excess supply has been used to water golf courses and make artificial snow for a ski slope in semi-desert Urumqi. But scientists say the glut is unsustainable because it comes from the release of water that has built up over thousands of years.
"At the moment there is plenty of water in the big cities. But it is hard to say how long it will last," said He Yuanqing, a glaciologist at Careeri. "On one hand, global warming is accelerating the melt. But on the other, it is increasing rainfall, so we need a way to store the extra water."
Estimates of how long it will take Urumqi's glacial water supplies to start to decline range from 40 to 100 years.
It is unclear, however, how long the water can be stored without replenishment. Experts have previously called for the reservoirs to be built underground so that the water does not evaporate in the summer, when Xinjiang has the highest average temperatures in China.
Over-exploitation of river systems and oases has exacerbated the problem. The volume of water in the once vast Aibi lake in Xinjiang has decreased by two-thirds over the past 50 years, the Beijing News reported today.
In terms of glacier melt, the worst affected area in China is the Tibetan plateau, often described as "the roof of the world". Last month, Chinese scientists warned that glaciers on the plateau had lost 989 million cubic metres over the past 40 years and were continuing to melt at a "worrying speed". They added that ice fields had shrunk by 196 sq kilometres, equivalent to a quarter of New York city.

Coastal processes
Erosion
The sea changes and shapes the coastal landscape. Erosion is the wearing away and breaking up of rock and beach material found along the coast. Destructive waves will erode the coastline in the following four ways.
- The constant force of waves crashing on the shore damages it. This is called hydraulic action.
- Waves bring with them bits of rock and sand. These help to grind down cliffs. This is called abrasion.
- Waves cause rocks and pebbles on the shore to smash into each other and break down. This is called attrition.
- Acids contained in sea water will slowly dissolve certain types of rock. This is called corrosion or solution.

Welcome to Breathing Earth. This real-time simulation displays the CO2 emissions of every country in the world, as well as their birth and death rates.
Please remember that this real time simulation is just that: a simulation. Although the co2 emission, birth rate and death rate data used in Breathing Earth comes from reputable sources, data that measures things on such a massive scale can never be 100% accurate. Please note however that the co2 emission levels shown here are much more likely to be too low than they are to be too high.

FEMA: Are You Ready?
You may need to survive on your own after a disaster. This means having your own food, water, and other supplies in sufficient quantity to last for at least three days. Local officials and relief workers will be on the scene after a disaster, but they cannot reach everyone immediately. You could get help in hours, or it might take days.
Basic services such as electricity, gas, water, sewage treatment, and telephones may be cut off for days, or even a week or longer. Or, you may have to evacuate at a moment’s notice and take essentials with you. You probably will not have the opportunity to shop or search for the supplies you need.

Portraits from the Congo
In the Democratic Republic of Congo (DR Congo), fighting continues among various rebel armies, tribes, the Congolese army and U.N. forces. The dire situation has prompted the government of DR Congo to ask for help, and invite the armies of neighboring South Sudan, Rwanda and Uganda to enter their territory on several joint operations, to hunt down and pacify or dismantle at least two major rebel armies operating in the lawless border region. Rebel leader Laurent Nkunda was captured in January by Rwandan forces, but his army is still active - and Ugandan troops are seeking out the rebel Ugandan Lord's Resistance Army, which has taken refuge in eastern DR Congo. Once more, caught in all of this are the local civilians, terrorized by fleeing and advancing troops of all kinds. Reuters photographer Finbarr O'Reilly has been traveling through the area, capturing some amazing photographs of the people involved. (38 photos total)

The fight for water in North America
The arid states of America's south-west have been getting drier in recent years.Since 2000, the Colorado River - which provides water for seven US states in the region - has carried less water than at any time in recorded history. And while the drought is worsening, the demand for water in this booming part of the country is increasing. The states dependent on the Colorado River for their water are seeking solutions to their water shortage, with some suggesting that importing water from far-flung states - or even towing icebergs down from the Arctic - could solve the problems.
