Dordrecht, The Netherlands: Martinus, Nijhoff. ABSTRACT INTRODUCTION Desertification of the arid lands of the world has been proceedingsometimes rapidly, sometimes slowlyfor more than a thousand years. It has caused untold misery among those most directly affected, yet environmental destruction continues. Until recently, few if any lessons seemed to have been learned from the past, in part because the problem was an insidious one that went unrecognized in its early stages or was seen as a local one affecting only a small population, and in part because new land was always available to start over again. As long as remedial action could be deferred by moving on to new frontiers, land conservation had little appeal. It was not until the 20th centurywhen easy land expansion came to an endthat governments and people finally realized that continued careless degradation of natural resources threatened their future. INTERNATIONAL DIRECTIONS The decade of the 1950's witnessed the first worldwide effort to call attention to the problems and potentials of arid regions. It started when the United Nations Educational, Scientific, and Cultural Organization (UNESCO) launched its Major Project on Scientific Research on Arid Lands in 1951. That project led to publication of a newsletter, the provision for funds for establishing and strengthening arid land research institutes, organization of conferences and symposia, and publication of a series of research reviews and special reports on a wide range of topics. The Major Project was terminated in 1962 and the arid land program was merged with the broader UNESCO natural resource program.

Its aim is to keep an international readership informed about the work IDRC supports in developing countries as well as other development issues of interest. PREVIOUS ISSUES: July 1994 (Volume 22, Number 2) DRYLANDS AND DESERTIFICATION The path from the 1992 UNCED Conference in Rio de Janeiro to a global Convention on Desertification an initiative pursued with particular interest by African nations will have taken some two years of careful and, at times, painstaking negotiation. IDRC is pleased to have supported participation by African NGOs and other key players in the negotiating process. The importance of this convention can be measured alongside those on Climate Change and Protection of the Ozone Layer. Its great significance lies in the seriousness of the issue it addresses and its utility as a framework for action to protect the environmental integrity of arid, semi-arid and dry sub-humid areas. Success in this regard could help secure the livelihoods of all those who rely on the natural resources of the threatened areas and safeguard the food security of millions of vulnerable people. With the completion of the Convention comes the difficult work ahead: developing national action programs and securing sufficient funding to carry them out. If the Convention is not to become "just another document," in the words of Bo Kjellen, Chair of the intergovernmental negotiating committee, this work will require the further long-term commitment of resources and energy on the part of governments, NGOs, local communities and bilateral and multilateral donors.

Extractions: climate science Climate Change and the Mediterranean Region Executive Summary Water shortages and poor harvests during the droughts of the early 1990s exposed the acute vulnerability of the Mediterranean region to climatic extremes. Against this backdrop, the prospect of a major climate change brought about by human activities is a source of growing concern, raising serious questions over the sustainability of the region. This report examines the potential implications of global climate change for the Mediterranean region. Drawing on the results of recent studies, it reviews possible changes in climate together with recent trends, the potential impacts of climate change and the implications for sustainable development. One key finding is that future climate change could critically undermine efforts for sustainable development in the Mediterranean region. In particular, climate change may add to existing problems of desertification, water scarcity and food production, while also introducing new threats to human health, ecosystems and national economies of countries. The most serious impacts are likely to be felt in North African and eastern Mediterranean countries. The report concludes that while there is some scope for adaptation, ensuring the long-term sustainability of the region requires urgent action to cut global emissions of greenhouse gases.

Extractions: In 1991 the Indians, working with Survival International, an NGO based in England, prepared a land claim report that demonstrated that at least 162,000 acres spread over the two State Plots traditionally belonged to them. Later that year, the provincial Governor signed a decree (No. 2609/91) recognizing that the area was indeed Indigenous land, and pledging to recognize this in law. The succeeding Salta government failed to take any decisive action, and allowed the situation to deteriorate dramatically. Shortly before leaving office at the end of last year, the same government presented a draft land bill to the provincial parliament that is completely against the interests of the Indians and, if approved, would deprive them of huge tracts of their territory.

We have sent letters. Meetings take place, new laws and decrees are passed, and yet more topographic studies... We are now in the fourth administration. Yet they have not responded to our demands. Years pass and our lands become impoverished, because the people who have come from the outside to occupy them Know not how to manage them. Years pass and we become poorer.

http://www.cru.uea.ac.uk/cru/tiempo/issue08/desert.htm

Extractions: Michael Bernard Kwesi Darkoh discusses the complex factors underlying the threat to Africa's drylands. WITHIN THE LAST DECADE or so, 25 countries in Africa have faced drastic food shortages as a result of the extended drought. The reduced capacity for food production has brought a population of over 200 million people to the verge of calamity. Some have died of starvation, and among the survivors, especially the children and young people, many will suffer impaired health for the rest of their lives. The international community brought in emergency aid, both in the form of food supplies and of technical assistance in rehabilitating drought victims. However, the drought hazard in Africa can be expected to continue, recurring at unpredictable intervals. It cannot be overcome by one-time massive injections of emergency aid. A long-range strategy must be developed which is capable of being realized under the given constraints of these impoverished regions through sustainable development of their fragile environment. The droughts and famines that have swept over Africa in the past and which are likely to strike again are not sudden natural disasters. Nor are they simply caused by lack of rainfall. They are the end-results of a long deterioration in the ability of Africa to feed itself, a decline caused largely by mistakes and mismanagement - both inside and outside the continent.
