Steppe desertification due to vehicle travel is a severe environmental issue in Mongolia. We studied natural vegetation recovery on abandoned vehicle tracks in the central Mongolia steppe through vegetation surveys and stable isotopic techniques. The following issues were addressed: (i) invasion of pioneering plant species, (ii) alteration of soil surface features, and (iii) contribution of revegetated plants to soil organic matter (SOM).

The people of the Sahel — that huge region stretching along the southern edge of the Sahara Desert — are still striving to recover from the fallout of the terrible droughts that have afflicted the area since 1973. Drought has shattered the momentum of socioeconomic development in Burkina Faso, Mali, Mauritania, Niger, and Senegal. According to researchers with Burkino Faso’s Institut de l’environnement et de recherches agricoles, “Rural men and women are now struggling to survive in a land that is exhausted, denuded, desiccated, and swept away by the wind and water.”

This report presents a panorama of the environmental status of the world’s deserts: their location and extent, uniqueness and vulnerability, biodiversity and natural resources. The report provides a balanced picture of deserts as ecosystems which form a special part of the world’s natural and cultural heritage, and not simply as land that is the end result of the process of desertification.The Global Deserts Outlook is the first thematic assessment report in the Global Environment Outlook (GEO) series of the United Nations Environment Programme (UNEP).

World grain production is a basic indicator of overall food security at the global level. Since 1984, world grain production has expanded more slowly than the world’s population. By the early years of the 21st century, consumption has outstripped production. Could these trends herald a new "politics of scarcity"?In this article, the author sets out the evidence for his assertion that the world faces a future food security crisis.First, based on current trends, demand for grain will increase significantly over the coming years.

This paper presents the proceedings of a United Nations Convention to Combat Desertification (UNCCD) held in December 2005. The report presents the workshop programme, objectives and methodology. Four papers were presented at the workshop, ensuing discussions by the participants are also included.

This report highlights the major biological factors that contribute to ecosystem resilience under the projected impacts of global climate change. It assesses the potential consequences for biodiversity of particular adaptation activities under the thematic areas of the Convention on Biological Diversity, provides methodological considerations when implementing these activities, and highlights research and knowledge gaps.

This paper reports on a workshop held in Ethiopia in 2004, targeting stakeholders involved in implementing Ethiopia’s National Action Plan (NAP) for the United Nations Convention to Combat Desertification (UNCCD). The workshop was based on international, national and regional experiences, principles and practices related to dryland management and combating desertification to the development of community driven processes.

Site degradation occurs mainly through deterioration of the soil's capacity to capture and store water, as well as the loss of organic matter or the accumulation of salts or other toxic substances in the soil. This degradation process, leading to the reduction of the biotic potential of the site, is known as desertification. In this study, changes in bulk density, organic matter, and electrical conductivity are used as indicators of desertification in northeast Mexico.
