Desertification: a project named DESIRE


Creeping desertification around the world affects more than 250 million people.

A newly launched research project is working to fight the phenomenon with new conservation strategies.

Funded under the EU’s Sixth Framework Programme (FP6), the DESIRE project is international, bringing together 28 research institutes, non-governmental organisations (NGOs) and policy-makers from around the world.

The aim of the €9 million project is to come up with alternative strategies for the use and protection of these vulnerable areas.

‘Fragile arid and semi-arid ecosystems are in urgent need of integrated conservation approaches that can prevent and reduce widespread degradation,’ said the coordinator of the project, Professor Coen Ritsema from the Alterra Wageningen University & Research Centre, the Netherlands.

The team of researchers has identified 18 hotspots from southern Europe to Australia, Chile and the United States of America, covering a wide range of problems, from soil erosion by wind or water, to salinisation and droughts or flash floods.

 Water Harvesting in Chile

1 month ago by wateris.

The Atacama Desert in northern Chile is one of the driest places on earth. The Andes mountains block rain from falling, but the area is often covered with a layer of fog, called camanchaca. The fishing village of Caleta Chungungo lies on the edge of the desert and once recieved its water supply from a nearby iron mine. When the mine closed water had to be brought in on trucks and there was never enough for villager’s needs. In order to collect water in the clouds above a fog collecting system was installed near the location of the old mine. Large mesh nets were set up on the slopes, and when the fog hits the mesh the water in the clouds condenses and runs into a trough which collects into a reservoir. The water harvesting system provides the village with potable and irrigation water, enough to meet their needs.

Re-Read Drought Hazard

I. Definition of Drought

Generic definition of drought is a persistent and abnormal moisture deficiency having adverse impacts on vegetation, animals, or people. Drought is a creeping phenomenon, the extent of which appears gradually, thus offering the possibility for monitoring and early warning of drought. There are two ways to monitor droughts: one is based on a network system of stations, and another is by remote sensing, which offers fast, objective, economic, and large-range characteristics. Through remote sensing, station networks, and modern communications, including geographical information systems (GIS), a variety of information about climate and water supply conditions can be provided continuously before drought occurs. This information is useful for defining the possible range, period, and risk degree of drought, and it will help in the adoption of drought mitigation measures.

Many of expert explain drought on more operational definition as
: a deficiency of precipitation from expected or “normal” that, when a season or longer period of time extended over, is insufficient to meet demands.

This may result in economic, social, and environmental impacts. It should be considered a normal, recurrent feature of climate. Drought is a relative, rather than absolute, condition that should be defined for each region. Each drought differs in intensity, duration, and spatial extent.

Drought Threatens 1.5 million in Southwest China

BEIJING, Feb 27 (Reuters) – Drought in southwestern China is threatening the drinking water supplies of 1.5 million people and authorities are considering seeding clouds to make it rain, state media said on Tuesday. The problem has been compounded by last summer’s heat wave in the densely populated municipality of Chongqing, as water supplies have still not recovered, the Beijing News said.

Drought affects millions in Thailand

BANGKOK (AFP) – Scorching weather and lack of rain has left more than eight million people in Thailand, the world’s top rice exporter, suffering a drought that is ruining their farmland, officials said Sunday. The drought has hit 58 of Thailand’s 76 provinces, the government department responsible for disaster prevention and management said in a statement. Most of them are in the north of the country, a region only just recovering from a choking haze caused by forest fires. The department said about 114,000 rai (45,000 acres) of farmland had been affected, along with 8.23 million people. Authorities said water pumps were being provided to help local farmers and residents.
