Climate change 'hitting Africa'
Climate change is already affecting people across Africa and will wipe out efforts to tackle poverty there unless urgent action is taken, a report says.

Droughts are getting worse and climate uncertainty is growing, the research from a coalition of UK aid agencies and environmental groups says.

Climate change is an "unprecedented" threat to food security, it says.

It calls for a "climate-proof" model of development and massive emissions cuts to avoid "possibly cataclysmic change".

The report, Up In Smoke 2, updates previous research from the organisations - Oxfam, the New Economics Foundation and the Working Group on Climate Change and Development, an umbrella group of aid and green groups.

It says that although climates across Africa have always been erratic, scientific research and the experience of the contributing groups "indicates new and dangerous extremes".

...

Andrew Simms, from the New Economics Foundation, said: "Global warming is set to make many of the problems which Africa already deals with, much, much worse," he said.

1. Sahara has been growing. But now even more. Deforestation and lack
of rainfall. Add that to poor soil. What a nightmare.

3. A few happy statistics on desertification:

  • 1.9 billion hectares of land degraded.

  • 65% (500 million hectares) of African land degraded.

  • Arable land loss is 30-35 times the historical rate.

  • Loss is equal to 20 million tons of grain per year.

  • 70 percent of the 5.2 billion hectares of drylands used for agriculture are already degraded and threatened by desertification.

    2. This website brings tears to the eye.. Lake Chad (and other disasters)

    Irrigation / Water Problems: Lake Chad, once one of the African continent's largest bodies of fresh water, has dramatically decreased in size due to climate change and human demand for water. Once a great lake close in surface area to North America's Lake Erie, Lake Chad is now a ghost of its former self. According to a study by University of Wisconsin-Madison researchers, working with NASA's Earth Observing System program, the lake is now 1/20th of the size it was 35 years ago.

    Found at the intersection of four different countries in West Africa (Chad, Niger, Nigeria, and Cameroon), Lake Chad has been the source of water for massive irrigation projects. In addition, the region has suffered from an increasingly dry climate, experiencing a significant decline in rainfall since the early 1960s.

    The most dramatic decrease in the size of the lake is shown in the fifteen years between January 1973 and January 1987. Beginning in 1983 the amount of water used for irrigation began to increase. Ultimately, between 1983 and 1994, the amount of water diverted for purposes of irrigation quadrupled from the amount used in the previous 25 years. The red color denotes vegetation on the lake bed and the ripples on the western edge of the lake denote sand dunes formed by the wind.

    The bottom picture is a composite of Landsat-7 images from November 2000 to February 2001 showing the present stage of Lake Chad. The small patch of blue that is now the lake stands in stark contrast to the wide swath of the old lake bed (shown in green, indicating vegetation).



    THIS LINK FROM VOA, HAS A VERY GOOD ARTICLE ABOUT THE VANISHING LAKE:

    7. Before you can get poor countries to lower the birthrate,
    they have to be relatively certain that the fewer children they have will survive. :(

    Countries with stable governments, fewer wars, and higher standards of living have lower birth rates too..

    Eradicating war and poverty is the FIRST step.

    8. Right on. And *communally* guaranteeing that the aged will be cared for
    since large families are the social-security of the poor, in trad societies.
