PlayPump water system example of Intermediate Technology

While children have fun spinning on the PlayPump merry-go-round (1), clean water is pumped (2) from underground (3) into a 2,500-liter tank (4), standing seven meters above the ground. A simple tap (5) makes it easy for women and children to draw water. Excess water is diverted from the storage tank back down into the borehole (6). The water storage tank (7) provides a rare opportunity to advertise in outlaying communities. All four sides of the tank are leased as billboards, with two sides for consumer advertising and the other two sides for health and educational messages. The revenue generated by this unique model pays for pump maintenance.
The design of the PlayPump water system makes it highly effective, easy to operate and very economical, keeping costs and maintenance to an absolute minimum. Capable of producing up to 1,400 liters of water per hour at 16 rpm from a depth of 40 meters, it is effective up to a depth of 100 meters.

Driving Ban Lowers Beijing Pollution

Driving Ban Lowers Beijing Pollution

In an effort to control smog during the 2008 Olympics, Beijing officials planned to institute a number of pollution-curbing measures. One such measure is to limit the number of vehicles on the roads. The Summit of the Forum on China-Africa Cooperation, held in Beijing on November 4-5, 2006, gave officials the opportunity to see just how much pollution would be reduced if traffic were restricted. Between November 4 and November 6, officials banned government and commercial vehicles, restricted the use of private vehicles, and limited access to certain roads. Buses ran more frequently to provide transport within the city. News reports estimated that approximately 30 percent of the city’s vehicles were taken off the road during the three-day restriction period.

Orbiting overhead once a day, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite recorded nitrogen dioxide levels. Looking through the column of air that sat between the satellite and the city, the instrument summed up the average number of nitrogen dioxide molecules per square centimeter. The data it sent back to Earth showed a drop in nitrogen dioxide levels over Beijing between November 4 and November 6, as illustrated by these images. High concentrations of nitrogen dioxide are represented by bright yellow squares over China’s major cities. The cities, and their corresponding pollution “hotspots” stretch across the North China Plain from north to south, with Beijing reigning in the north. On November 5, center, nitrogen dioxide levels dropped over the entire country, but the decrease is most dramatic over Beijing which went from turquoise-yellow (high) to dark blue (low) back to yellow before, during, and after the restriction period.

The graph illustrates the drop in nitrogen dioxide over Beijing in greater detail. Though concentrations jumped from day to day between October 25 and November 19, sometimes to concentrations as low as levels seen during the summit, the only time nitrogen dioxide levels remained below 20x1015 molecules per square centimeter for more than a single day was during the summit when traffic was restricted. The graph is from a paper by Yuxuan Wang and colleagues from Harvard University and the Royal Netherlands Meteorological Institute, published in Geophysical Research Letters on April 28, 2007. The scientists estimated that nitrogen oxide emissions were reduced by 40 percent during the restriction period.

What Is GeoSquishing?

the basic idea is, you find a famous or infamous location which you believe to have some relevance and GeoSquish it. For example Bodie Island Lighthouse being GeoSquished.

The village that was swallowed by the sea

Just an hour's drive south of the Thai capital Bangkok , the small coastal village of Khun Samutchine is facing a daily battle with the sea. The sea is coming in at an alarming rate

The village is suffering from the effects of severe coastal erosion: the sea comes in at a rate of approximately 25 metres a year. Environmentalists say the erosion experienced in the area is probably some of the worst in the world. Dr Thanawat Jarupongsakul, a scientist from Bangkok's Chulalongkorn University says that climate change has helped cause the loss of nearly 600 km of Thailand's coastline. "Climate change has resulted in more intense waves and rougher seas during the monsoon period," he said. "The average height of waves used to be between one and 1.5 metres, but now it has increased to between two and four metres high." Go to SOURCE for rest of article..

Flying addicts take dim view of air taxes in poll

Britain has become a nation addicted to flying, according to a Guardian/ICM poll out today. It shows that more than two-thirds of people have travelled by plane in the last five years and reveals widespread opposition to government action aimed at cutting the number of people who fly in order to limit climate change.

The poll does reveal a growing level of concern about the impact of air travel. Almost half of air travellers claim they have changed their behaviour in response to fears about the impact on the environment.

But these fears are not being translated into backing for official action. Voters remain strongly opposed to government action to control the rapid growth of the airline industry, such as raising tax levels on air tickets to restrict low-cost airlines. More travellers want taxes on air travel cut than want to see them increased: 30% want a reduction and only 20% higher taxes. Many people (46%) think that tax levels should remain the same, although environmental groups, the Conservative party and the Liberal Democrats all support some form of increase.

At present, airlines do not pay tax on the fuel they use. Air passenger duty, doubled by the chancellor in February to between £10 and £80 a ticket, is regarded as too low by many campaigners. But only 18% of Tory voters back a rise despite their party's policy on reforming air taxes, launched earlier this year. Labour voters are equally hostile, with only Liberal Democrat supporters more in favour of increases than tax cuts.The poll shows that 68% of respondents have travelled at least once by plane in the last five years. Cheap flights have boosted the number of people travelling by air, with airlines such as Ryanair currently offering "10m seats at £10".

But flying remains a middle-class habit: 83% of people in the top AB economic group have flown recently, against 52% of DEs at the bottom of the scale.

Air travel is also weighted towards the south of the country, with 72% of southerners flying in the last five years against 66% in Scotland and the north.

Only 13% of passengers say that they have given up flying as a result of climate change. But 34% of people who fly say that they have cut down on the short-haul trips they take as a result of climate change. A similar proportion, 31%, say that they have reduced long-haul flying.The growing number of air travellers suggests that the reality may differ. People at the top of the economic scale are the least likely to claim they have taken action to help the environment.

Many air passengers also say that they have tried carbon offset schemes to neutralise the impact of their journeys: 29% of all passengers say that they have used such a scheme.Again, that claim may be running ahead of what is actually happening. A recent Financial Times investigation suggested the industry was still in its infancy, with a lack of clarity about how off-setting and carbon trading schemes should work.· ICM interviewed a random sample of 1,003 adults aged 18+ between May 18 and 20. Interviews were conducted across the country and the results have been weighted to the profile of all adults.

Multinational coffee companies now rule our shopping malls and supermarkets and dominate the industry worth over $80 billion, making coffee the most valuable trading commodity in the world after oil.

But while we continue to pay for our lattes and cappuccinos, the price paid to coffee farmers remains so low that many have been forced to abandon their coffee fields.

Nowhere is this paradox more evident than in Ethiopia, the birthplace of coffee. Tadesse Meskela is one man on a mission to save his 74,000 struggling coffee farmers from bankruptcy. As his farmers strive to harvest some of the highest quality coffee beans on the international market, Tadesse travels the world in an attempt to find buyers willing to pay a fair price.

Against the backdrop of Tadesse's journey to London and Seattle, the enormous power of the multinational players that dominate the world's coffee trade becomes apparent. New York commodity traders, the international coffee exchanges, and the double dealings of trade ministers at the World Trade Organisation reveal the many challenges Tadesse faces in his quest for a long term solution for his farmers.

American Food Aid to Malawi

US government deal, announced in April, to ship $19.5 million of American corn and soya to Malawi as food aid.

School-feeding programmes run by the Malawian government and various aid agencies have resulted in incraeses in stuents attending school. Children come to the school because of the meal - class numbers are up by about 7 per cent in every age group since the feeding programme began in January.In a country where only 70 per cent of the children attend primary school, that's an achievement. At another nearby primary, where an Oxfam partner supplies milk to mix into the free porridge, the head teacher, Annie Jana, told me that she now had 800 eight-year-olds, compared to 500 when the programme started a year ago. 'Absenteeism has fallen, and even children who dropped out are coming back, especially girls.' And in Malawi, getting girls into school has always been difficult - which is why half of all women are illiterate.

In April the US Government announced that it wanted to join in. It would give WFP nearly $20 million over three years to help fund an expansion of the programme so, from 2008, 650,000 Malawian children get a daily mug of porridge at school. At the same time it announced similar schemes for Kenya, Cambodia, Guinea and Pakistan - a total spend of $85.9 million.

The problem is - though WFP left this detail out of their press release - that the US grant came with a condition: it had to be spent on American CSB to be bought from American farmers and put in American ships to be transported to Malawi. According to WFP, the cost of buying, transporting and packing the annual 8,000 tonnes of US CSB will be $812 a tonne. SIR, which will buy about 3,600 tonnes of Malawian CSB - likuni phala - this year, expects to pay around $320 a tonne (distribution costs add another 5 per cent). Simply, if the American money was spent in Malawi, it could feed nearly two-and-a-half times as many schoolchildren.
