This article is over 7 years old Desertification on the outskirts of the town of Annakila, Mali. Madeleine Bunting for the Guardian Desertification and land degradation is "the greatest environmental challenge of our time" and "a threat to global wellbeing", according to the UN's top drylands official, Luc Gnacadja, who says people must be paid via global carbon markets for preserving the soil. Conflicts and food price crises all stem from the degradation of land, he added.

Evolution, Status, and Key Issues Introduction Desertification is the degradation of land in arid, semi-arid, and dry sub-humid areas collectively known as drylands. In the past, drylands generally recovered from drought, but contemporary human activities in many areas may undermine their recovery.

Complicating the problem is that desertification is not the same everywhere, and key factors are site-specific. Among the contributing factors in a particular area are the natural environment, natural and other disasters, local and international economic conditions, land laws and customs, and technologies employed on the land.

While land degradation and poverty often are linked, the nature of the relationship is unclear. Some experts conclude that land degradation is a primary cause of poverty in the most arid countries, but it also has been asserted that the relationship is circular—land degradation leads to poverty, which leads to land degradation, in a continuing cycle.

Many observers agree that the confluence of poverty and land degradation contribute to diverse social problems, including famine, civil strife, and mass migration. The economic loss from desertification is substantial. These figures have not been updated for several years.

Desertification: How can we prevent or reverse desertification?

These measures may be difficult or controversial to implement in particular areas, because they may require changes in longstanding practices. In recognition of the global nature of the problem, the Treaty contains four regional annexes for combating desertification in Africa, Asia, Latin America and the Caribbean, and the Northern Mediterranean.

Accordingly, combating desertification has been a priority of Africans in discussions about the environment. Some 18 developed countries, including the United States, are directly affected by desertification.

Desertification in the United States has been associated with western grazing and water management practices. The United States has a long history of managing its drylands and combats drought through a variety of programs and institutions.

The indirect effects of desertification abroad have been widely noted. Desertification may prompt increased U. Under the plan, carried out by the UNEP, relatively little money was spent on various remedies including 3 Ibid.

Again, these figures have not been updated on the Desertification Treaty web site. Hereafter referred to as Administration fact sheets. Despite this and other efforts, in the UNEP determined that overall land degradation had worsened, although in limited areas the problems had been remedied.

A lack of coherent assistance for affected countries has been cited as a primary reason for the failure of previous anti-desertification efforts. African countries in particular supported this proposal, and the United States backed it after overcoming initial reluctance.

As of August 9,countries have ratified the Treaty, including nearly all major developed countries. Ratifying countries are considered Parties to the Treaty, responsible for its implementation. Other countries may become Parties 90 days after their ratification of the Treaty.

Following the adoption of the Treaty, the INCD held five additional negotiating sessions for a total of ten sessions.

These sessions addressed interim activities to implement the Treaty, such as a resolution regarding urgent action in Africa, before the Treaty took effect and the First Conference of the Parties COP convened in Countries may bring the Treaty into force through procedures other than ratification.

For instance, non-signatory countries may accede to the Treaty at any time. In this section, ratification is used to encompass these other procedures.

For the text of the Treaty, including its annexes, see [http:Desertification poses one of the greatest environmental challenges today and constitutes a major barrier to meeting basic human needs in drylands.

Desertification is land degradation that affects biological productivity as well as the livelihoods of millions of people. Desertification in Niger World Regional Geography Desertification in Niger is a very progressive threat that is affecting not only the nation but .

The United Nations Convention to Combat Desertification in Those Countries Experiencing Serious Drought and/or Desertification, Particularly in Africa (UNCCD) is a Convention to combat desertification and mitigate the effects of drought through national action programs that incorporate long-term strategies supported by international .

Desertification is a type of land degradation in which a relatively dry area of land becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. It is caused by a variety of factors, such as through climate change.

Summary for Decision-makers Desertification is defined by the U.N. Convention to Combat Desertification as “land degradation in arid, semiarid and dry subhumid areas resulting from various factors, including climatic variations and human activities.”.

Desert A desert is an arid land area where more water is lost through evaporation than is gained from precipitation. Deserts include the familiar hot, dry desert of rock and sand that is almost barren.
