Desertification Information System to support National Action Programmes in the Mediterranean (DIS/MED) 1. Project purpose: 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.

Desertification is the expansion of desert lands into previously non-desert areas. The process occurs due to both natural and human causes. Deserts occur anywhere where there is less than 10 inches of rainfall each year. If an area receives only slightly more than this, its ecosystem is fragile and is a candidate for desertification. Desertification at Work. Photo Credit: Olafur Arnalds Long droughts can cause desertification to take place by removing the soil. If humans cause the loss of the soil, such as by overgrazing, over-cultivation, deforestation irrigation , and excessive plowing, desertification can follow. In many developing countries, problems such as high population growth and poor land use are causing desertification. Presently, desertification is occurring with greatest rapidity in the African Sahel. The desertification process can be a catastrophe for the inhabitants of an area. By preventing the growing of food, desertification can lead to famine and poverty. Already desertification has ruined huge amounts of land. Across the world, the total amount of land that has been lost is about equal to the size of Brazil (2 billion acres or 810 million hectares). Annually, 15 million acres (6 million hectares) are lost to desertification. Today, in most developed counties, trees are being replanted faster than they can be cut down, so desertification is not as severe a threat.

The year will highlight the growing threat that desertification represents for humans, and celebrate the unique ecosystem and cultural diversity of deserts worldwide. There is a difference between the need to fight against desertification as a threat to sustainable development and the protection of deserts as unique natural habitat.

Home A series of postage stamps to mark the International Year of Deserts and Desertification are to be issued in cooperation with the Universal Postal Union. It expressed pleasure in lending support to the International Year in International Bureau Circular No. 170, released in Berne on 30 May 2005. The additional awareness and publicity generated by the various stamp designs will serve to further highlight the cause and give added value to the UNCCD's mission. Building upon the approach promoted by the United Nations General Assembly, the stamps should seek to portray the duality of the issues at stake: conserving deserts as a unique natural habitat for mankind, while combating the threat to livelihoods posed by desertification. They should therefore demonstrate the beauty of the drylands as well as the importance of protecting them from further damage. Any stamps and philatelic products produced by the postal administrations will be included in an exhibition of various awareness materials. Home Background Promotions Press ...

A Security Issue Workshop on Desertification in the Mediterranean Region. A Security Issue The workshop resulted in a book publication which focused on two basic concepts: security and desertification in the Mediterranean Region and their linkages. Desertification is recognized as a process of land degradation in arid, semi-arid, and dry sub-humid areas of the world that is the result of natural phenomena (e.g. climate variation) and anthropogenic factors. The outcome of this type of degradation has typically been considered to be either a reduction or a loss of both biological and economic productivity. The book is divided into six special topical areas dealing with: Linking Environmental Condition to Security Assessing Regional Conditions Assessing Land Use Change Relative to Human-induced and Natural Cause Opportunities for Regional Cooperation and Information Sharing Soil and Vegetation Monitoring Development of Regional Desertification Indicators and Forecasting Techniques During the workshop an array of government diplomats, security specialists, and social and physical scientists from the Middle East, North Africa, Europe, and North America reviewed the actions of past and current Mediterranean land use practices. Their focus was environmental security, environmental consequences, and challenges for the future. This book provides a multi-lateral forum for continued cooperation, information exchange, and dialogue among the environmental, development, foreign and security policy communities within the Mediterranean Region. It may provide a precedent for further cooperation and partnership, including other more advanced conferences and publications, on assessing the condition of the entire region and the subsequent impacts and linkages to environmental security.

Large-scale plantation of trees will increase the land's productivity and re-generate the soil. Tree-nation is an online community in which you can buy your own tree and become the guardian of a real and happy tree that we will plant in our park in Niger. Our objective is two-fold: Primarily environmental, but also closely linked to the humanitarian aid that it will provide in the long term. The project will benefit local populations in terms of welfare, education and farming practices. And that's not all… The benefits of preventing desertification extend beyond trees to other kinds of plant and animal life. Any opportunity to re-introduce and/or help prevent any endangered species will therefore become an integral part of our mission. 2- Why?

CGIAR on Global Issues: Areas of Research Impact Genebanks ... Challenge Programs Combating Desertification through Science Recognizing the severity of the problem, the United Nations has declared 2006 as the International Year of Deserts and Desertification. At its core, desertification is about land degradation that decreases agricultural productivity, reduces biodiversity, and degrades the environment while diminishing ecosystem resilience. Caused by a combination of human-induced factors and climate change, desertification creates economic, environmental, and social hardship for millions of poor farmers who practice subsistence agriculture in fragile environments. Information Packet on Issues, Regions and CGIAR Contributions (10 fact sheets) For more than 35 years, CGIAR scientists and partners have been harnessing global knowledge to combat desertification and ameliorate its negative impacts on food, nutrition, and income security of poor people, while promoting the sustainable management of important natural resources such as biodiversity, forests, soils, and water. The results and benefits of these science-based efforts include: Hardy crops: New, high-yielding, stress- and disease-resistant crop varieties of beans, cassava, corn, grass pea, orange-fleshed sweet potato, pearl millet, rice, sorghum and wheat have been developed, and are increasing food availability in some the poorest, desertification-prone parts of the world.

THE POOR PARTNERS' ATTITUDES TO TECHNICAL COOPERATION IN AFRICA RIOD: THE DESERTIFICATION NETWORK By Massé Lo O f all the conventions stemming from the UN Conference on Environment and Development (UNCED) in Rio de Janeiro in June 1992, the Convention on Desertification is probably the one which gives the greatest importance to the activities of local communities, community organizations, and NGOs. The convention treats them as central to action programmes to fight desertification, both nationally and regionally. As for NGOs, they are treated as full partners by states, both to elaborate action programmes and to mobilize the necessary financial resources for their implementation. The decision to make local communities the main participants in the convention makes them unconditional partners in the implementation of the convention and of its regional annexes. It is also an invitation to countries threatened by desertification to change or improve their method of governance, especially in the management of natural resources. It is within this framework of new challenges and responsibilities that NGOs taking part in the convention's negotiations created the Réseau International d'ONG et OCB pour le suivi de la convention contre la désertification (RIOD) to bring the convention to the level of local communities and to make sure they take part in all phases of its implementation.

WDR 2008: Agriculture for Development Resources Contact Us Adobe Acrobat Reader 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.

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.

Desertification Deserts and desertification Facts Background Australia's response The global agenda Facts The 'World Day to Combat Desertification and Drought' is 17 June. Nearly one-third of the earth is classed as arid or semi-arid desert. An estimated six million hectares of productive land are lost every year because of desertification, land degradation and declining agricultural productivity. More than 110 countries are affected by desertification. Over 250 million people are directly affected by desertification and one billion people are at risk. These people include many of the world's poorest, most marginalised, and politically weak citizens. The African continent is most affected by desertification. Two-thirds of the continent is desert or drylands, almost three-quarters of which are degraded to some degree. Roughly 27 per cent of the China's land mass is desertified, with an average of 2,460 square kilometres of land being lost to advancing deserts each year. Nearly 400 million people live in these areas, and the economic loss to China has been estimated at around US$6.5 billion a year. It is estimated that US$42 billion is lost worldwide each year through desertification.
