Northern Africa in need of reforestation afrol News , 18 June Algeria and Tunisia are facing heavy costs due to deforestation and erosion, new studies demonstrate. While the Mediterranean area at large is facing desertification, North Africa was already seeing some of the great expenses of this trend. - Ill-conceived land use policies and unregulated management practices in the Mediterranean have resulted in over-exploitation of forest resources, according to the World Wildlife Fund (WWF). "This has led to acute environmental damage, biodiversity loss, and desertification, thus endangering the livelihoods of millions of people."
On the occasion of the World Day to Combat Desertification yesterday, the two environmental groups WWF and IUCN had asked Mediterranean national governments to "combat desertification on the ground by restoring forest landscapes and the full range of environmental and socio-economic benefits they provide."
In Tunisia alone the costs of desertification have been evaluated at US$ 100 million a year. Tunisia loses 8000 ha of land every year to desertification and Algeria loses 40,000 ha. About 66 percent of rural Mediterranean has a moderate to high risk of soil degradation, according to WWF estimations.

What is desertification?
The UNCCD defines desertification as the degradation of land in arid, semi-arid and dry sub-humid areas. Desertification occurs in arid, semi-arid and sub-humid areas - where the soils are especially fragile, vegetation is sparse and the climate particularly unforgiving. These areas are inhabited by one fifth of the world’s population. World map of aridity zones Source: CRU/UEA, UNEP/DEWA. Published

GRASSROOTS INDICATORS FOR DESERTIFICATION
Experience and Perspectives from Eastern and Southern Africa Book(s) 183 of 211 GRASSROOTS INDICATORS FOR DESERTIFICATION Experience and Perspectives from Eastern and Southern Africa Edited by Helen Hambly and Tobias Onweng Angura IDRC ISBN Out of print e-ISBN 1-55250-286-4 180 pp. "Knowledge is power" has become a common but true cliché in development research. And, as two sides of the same coin, "knowledge sharing" and "power sharing" lie at the root of many development problems, including drought and desertification. But what of grassroots knowledge? Measures or signals of environmental quality or change recorded by individuals, households, and communities are derived from local systems of observation, practice, and indigenous knowledge. They are grassroots indicators and, used effectively, may lead to the creation of new and more accurate development indicators, as well as improved processes for both planning and monitoring. This is the central focus of Grassroots Indicators for Desertification . The book documents why grassroots indicators should play a key role in the monitoring, evaluation, and reporting systems for sustainable development and, more specifically, in efforts to reverse desertification and other forms of land degradation. It also shows how their use would encourage local control of the generation and use of knowledge.

China Losing War With Advancing Deserts
Lester R. Brown
China is now at war. It is not invading armies that are claiming its territory, but expanding deserts. Old deserts are advancing and new ones are forming, like guerrilla forces striking unexpectedly, forcing Beijing to fight on several fronts. And worse, the growing deserts are gaining momentum, occupying an ever-larger piece of China's territory each year.
Desert expansion has accelerated with each successive decade since 1950. China's Environmental Protection Agency reports that the Gobi Desert expanded by 52,400 square kilometers (20,240 square miles) from 1994 to 1999, an area half the size of Pennsylvania. With the advancing Gobi now within 150 miles of Beijing, China's leaders are beginning to sense the gravity of the situation.
Overplowing and overgrazing are converging to create a dust bowl of historic dimensions. With little vegetation remaining in parts of northern and western China, the strong winds of late winter and early spring can remove literally millions of tons of topsoil in a single day soil that can take centuries to replace.

Restoring soil carbon can reverse global warming, desertification and biodiversity loss

February 21, 2008
Restoring the ability of soil to store carbon by promoting native grasses and vegetation can help reverse global warming, desertification and biodiversity loss, says an Australian researcher.
Tony Lovell of Soil Carbon P/L in Australia estimates that by actively supporting regrowth of vegetation in damaged ecosystems, billions of tons of carbon dioxide can be sequestered from the atmosphere.
In February 2008, Lovell discussed the potential of soil carbon restoration.
Mongabay: What are the advantages of increasing the capacity of soil to store carbon?
Lovell:
In arid and seasonally dry areas, continuous grazing creates disasters like that on the left. Returning to herding-style management with long recovery periods between grazings heals the land (right)
Determining how much carbon dioxide (CO2) can physically be consumed from the atmosphere?
LEFT: This river in Zimbabwe used to flow year-round. Then overgrazing by wandering livestock bared much of the soil in the surrounding area. Today the river flows only as flash floods following heavy rains. Biodiversity loss is severe, livestock are starving, and most wildlife has disappeared. RIGHT: This nearby river had similar problems. It now has water year-round, and flows during most of the year. Drought is rare, biodiversity is increasing, and wildlife has reappeared in large numbers. Soil Carbon P/L notes that capturing just 1 mm more rain per year means: 1 liter more usable water per square meter; 10,000 liters more water per hectare; 1,000,000 liters more water per square kilometer; Less drought, because more water stays in the soil to recharge rivers, springs, and wells; and more forage, because plants can also use that water.

    Desertification
    Drylands cover more than 40% of the world's surface but are increasingly being affected by desertification. Desertification is land degradation in arid, semi-arid and dry sub-humid areas resulting from climatic variations and human activities. It occurs because drylands are extremely vulnerable to over-exploitation and inappropriate land use (for example, deforestation, overgrazing, bad irrigation practices...)
    Desertification can lead to increased poverty, loss of land productivity, loss of biodiversity, internal and/or cross-border migrations of people, etc. More than 250 million people are directly affected by desertification. A further 1.1 billion people in more than 100 countries, many of which are World Bank development partners, are at risk from desertification. Data show that areas affected by desertification also tend to have the poorest, most marginalized and politically weak citizens.
    In response, the international community negotiated the Convention to Combat Desertification (CCD), which was ratified in 1996. As of March 2002, 179 Country Parties have signed the Convention. The CCD's framework focuses on human survival and conservation of natural resources and emphasizes multi-stakeholder commitment, participation, interdisciplinarity, and partnerships.

Word Desertification Day
Every June 17 is recognized as World Day to Combat Desertification by the United Nations. This year the day's theme was the linkages between climate change and desertification.
This past April, the UN's top scientific authority on global warming warned that higher global temperatures could significantly worsen desertification by changing rainfall patterns, melting glaciers and diminishing snow melt that the world's major rivers depend upon.
China, one of the world's worst hit countries , has seen thousands of Chinese villages disappear before its expanding deserts. The problem has been made worse by the legacy of Mao's Great Leap Forward, which sought to make China a self sufficient food producer by bringing marginal lands under cultivation. However, overuse of the land and

To improve the capacity of national administrations of Mediterranean countries to effectively program measures and policies to combat desertification and the effects of drought.
2. Background
The United Nations Convention to Combat Desertification (UNCCD) The UNCCD assigns particular relevance to the identification of criteria for the formulation and implementation of the National Action Programmes A n inter-regional workshop on the Desertification Information Systems for planning needs in the Mediterranean area was held in November 1998 in Marrakech, Morocco, jointly sponsored by the UNCCD Secretariat, the Authorities of Morocco and Italy. It convened representatives of Northern Mediterranean and of Northern Africa countries, as well as international and sub-regional organizations. The participants to the Marrakech workshop recommended to the Northern Mediterranean and the Northern African countries to explore the possibility of establishing an operational information system for planning purposes, to potentially service all Mediterranean partners, taking into account the existing local capacities and facilities. They also urged countries to establish a close collaboration for the harmonisation of the methodologies of exchange of information related to all aspects of land degradation. Tackling the problem of land degradation in the Mediterranean is a complex task due to the co-existence of various causes at different levels. In particular, the interlacing of institutional and technical causes entails to address both aspects at the same time.

http://www.ruralpovertyportal.org/english/topics/desertification/index.htm
Powered by IFAD updated: 14 September, 2007 About the portal contact us sitemap Rural poverty and desertification When fragile land in arid regions is overexploited by the demands of an expanding population, it loses its productive capacity. The results are devastating. Land degradation affects more than 1 billion people and 40 per cent of the earth’s surface. In the severest cases the land becomes infertile and useless, precipitating famine and drought. Every year 12 million ha of land are lost to desertification, and the rate is increasing. Desertification is a major environmental problem that is advancing at an alarming pace. Arid and semi-arid areas cover roughly one third of the earth’s surface. These dryland regions, which may or may not border on deserts, receive little or no rainfall. Their ecosystems are fragile and are easily stressed beyond their already limited capacity. In the past such regions were home to small groups of herders and small-scale farmers. The land was grazed intermittently and was left to lie fallow at intervals. Now dryland areas are increasingly subject to the pressures of a growing human population. The causes of desertification are many and complex, but it is essentially inappropriate and excessive human activity that initiates the process. Competition for land and limited resources lead to unsustainable land management practices. In some cases migration as a result of conflict puts undue pressure on fragile areas. In other cases it is mining that causes the initial damage.
