A line in the sand: Workers plant a web of shrubs in the desert to halt the advancing of sand dunes

Xinjiang, in Northwest China, is home to the country's biggest deserts. Fighting desertification is a constant for cities deep in the region, to avoid the fate of being buried like the ancient Loulan civilization more than 1,600 years ago.

The town of Qiemo, in the middle of the Taklimakan Desert, China's largest, has been fighting against the sand dunes pushing towards it. On the other side of the Qarqan River, the sand dunes are only two kilometers away at the nearest point. Three times in the town's history, the river running through it was diverted by shifting desert sands................the article and more images to...(Global Times)

Lake shrinks by third. (The sharp fall of the lake's water level will affect shipping and fishing as well as nearby residents' water supply)

China's largest freshwater lake, Poyang, has shrunk by one third over the last three days due to a reduced water supply from the Yangtze River and little rainfall.

At 8 am Wednesday, the lake's surface area was 1,490 square kilometers, a reduction of 679 square kilometers compared with 2,169 square kilometers on Monday, said the Jiangxi Provincial Hydrological Bureau on Wednesday. 

The water level at the Xingzi hydrological station was 11.99 meters at 4 pm Wednesday, 2.13 meters lower than the average level recorded in recent years. The water level is falling by 30 centimeters every day.


The two major causes for the lake shrinking were the reduced water supply from the upper Yangtze River due to the construction of dams and sparse rainfall over the past month in Jiangxi, said the bureau.

The precipitation was less than 5 millimeters since September 20 in Jiangxi Province.

The lake's flood season began on April 30 and lasted until October 18.

This year's flood period was 33 days longer than last year's.

The sharp fall of the lake's water level will affect shipping and fishing as well as nearby residents' water supply.

In fight against hunger, UN launches initiative targeting threat of desertification

 UN, 22 October 2014 – The growing menace of desertification poses a distinct threat to the world’s agriculture and eco-systems, the United Nations agriculture agency warned today, as it announced a new initiative aimed at curbing the spread of land degradation and building resilience to climate change.

The programme, named Action Against Desertification and launched by the UN Food and Agriculture Organization (FAO) in partnership with the European Union and the African, Caribbean, and Pacific Group of States (ACP), will devote some €41million to bolstering sustainable land management across the world’s most vulnerable areas in an effort to fight hunger and poverty.


“Desertification and land degradation are very serious challenges. They lead to hunger and poverty, themselves at the root of many conflicts,” FAO Director-General, José Graziano da Silva, said in a press release marking the programme’s launch.

“But recent successes show that these problems are not insurmountable. We can boost food security, improve livelihoods and help people adapt to climate change.”

The FAO reports that more than 70 per cent of people living in drylands and other fragile ecosystems across Africa, the Caribbean, and the Pacific derive their livelihoods from natural resources. At the same time, an uptick in population growth and climate change has placed increasing pressure on these ecosystems, intensifying degradation and desertification and putting millions of lives at risk.

In an effort to thwart the costly effects of desertification in Africa, the Action Against Desertification will build on an already existing “flagship programme” – the Great Green Wall for the Sahara and the Sahel Initiative – which supports local communities, Government and civil society in Burkina Faso, Ethiopia, Gambia, Niger, Nigeria and Senegal with the sustainable management and restoration of their dryland forests and rangelands.

Two-thirds of the African continent is classified as desert or drylands and climate change has led to prolonged periods of drought; over-intensive farming and over-grazing have caused land degradation; and deforestation has turned once fertile land into desert in many areas.

On that note, the FAO-backed programme it will support agro-forestry while also incentivizing the creation of farmer field schools where farmers can learn about the causes of desertification and the best ways to combat and prevent it.

Meanwhile, in both the Caribbean and the Pacific, the new initiative will target the problems of soil loss and degraded natural habitats by helping local communities adopt improved sustainable land and forest management practices.

UN opens high-level meeting on combating desertification.

WINDHOEK, Sept. 23 (Xinhua) -- Government ministers and other heads of delegation from 195 parties to a UN special convention on fighting expanding deserts across the globe started on Monday a two-day meeting here.

The high-level gathering begins as the 11th session of the Conference of the Parties (COP11) to the UN Convention to Combat Desertification (UNCCD), which opened in the Namibian capital on Sept. 16, went into its second week. The participants will discuss in the form of three round tables on topics including achieving a land degradation neutral world, promoting good practices in implementing the convention, and scaling up investments in avoiding land degradation and restoring degraded land.


In a message sent to the meeting, UN General Secretary Ban Ki- moon pointed out that healthy land is a prerequisite for food and water security and necessary to avert political instability.

"We need a paradigm shift to land stewardship. We need to work with countries and local communities to protect and sustain the world's fragile drylands and restore degraded land. This conference, under the theme 'A Stronger UNCCD for a Land- Degradation Neutral World', can make a valuable contribution in defining the way forward", said Ban.

Luc Gnacadja, outgoing Executive Secretary of UNCCD, said government officials and other key stakeholders participating in this high-level segment are supposed to share their guidance on how to build a stronger UNCCD, on how to overcome the hurdles of scaling up and disseminating good practice as well as their reaction to the promising evidence emerging from the work on the economics of land degradation.

They are also expected to bring political momentum to the deliberations of parties on the best options to foster the implementation of the convention, which was adopted in 1994 to counter the destructive force of desertification and mitigate the effects of drought through international cooperation.

A summary of the outcomes of the round-table discussions will be submitted to the COP11 meeting for further consideration.
At last year's "Rio+20" summit on sustainable development, world leaders pledged to strive to achieve a land degradation neutral world.
Such a world will be realized by way of preventing the degradation of healthy lands through sustainable land management and restoring land that is already degraded, according to the UN's plan.
To this end, the UNCCD secretariat is proposing that UN member states agree to a Sustainable Development Goal (SDG) on realizing zero land degradation by 2030.
"Land degradation and drought are drying up the future we want. I am fully convinced that our generation can go land-degradation neutral and can stop creating man-made barren lands or deserts", said Gnacadja.
