Au Burkina Faso, le potentiel en terres arables à vocation agricole est épuisé. À l’avenir, la population en rapide expansion ne pourra être nourrie que s’il est possible d’accroître les rendements sur les terres cultivées existantes. Grâce à la construction de cordons pierreux le long des courbes de niveau, il est possible de mieux exploiter l’eau de pluie et de stopper l’érosion.

Les communautés locales ont besoin d’aide afin d’atténuer les conflits opposant les populations à la faune.
Il est essentiel d'impliquer activement les populations autochtones et les communautés locales dans les efforts visant à conserver la faune afin de maintenir la biodiversité et d'assurer la durabilité des moyens d'existence ruraux, a annoncé aujourd'hui la FAO à l'occasion de la Journée mondiale de la vie sauvage.
Angola vai ter um órgão nacional para coordenar as medidas de combate à desertificação e mitigação dos efeitos da seca no país, conforme prevê a nova legislação sobre florestas, que substitui o regulamento florestal de 1962.
A nova legislação, que entrou em vigor este mês após promulgação pelo Presidente da República, José Eduardo dos Santos, prevê que o Estado deve elaborar "estratégias de médio e longo prazos" para programas nacionais de combate à desertificação e mitigação dos efeitos de secas, realidade que continua a afectar sobretudo populações no sul do país.
In the ten years since it came into being, the United Nations Convention to Combat Desertification (UNCCD) has had little or no effect on the further encroachment of deserts. More than 80 countries have submitted National Action Programmes to combat desertification, but they appear to lack the financial and political commitment to implement them. What are the causes behind the UNCCD's weakness? How can the Convention be incorporated more effectively and efficiently into the architecture of international development?
The United Nations Convention to Combat Desertification (UNCCD) is one of the three conventions agreed at the 1992 Earth Summit in Rio de Janeiro. But from the very outset it has led a marginal existence, because industrialized countries feel far less concerned with desertification than developing countries. Moreover, the Convention?s targets are not binding and are open to a variety of interpretations by the Parties.The conflicting interests of environmental and
development policy are weakening its position further.
Morocco is one of the African countries in which implementation of the UNCCD has progressed the furthest. In the Moroccan National Action Programme, integrated rural development, poverty reduction, drought mitigation and conservation of natural resources are the four cornerstones of effective desertification control.The country has succeeded in building up strong partnerships with most of its bilateral and multilateral development partners.
Despite ambitious desertification control programmes, the area of desertified land has expanded continuously since the establishment of the People's Republic of China, with increasingly serious impacts on important industrial and settlement areas. Only in the new millennium is a reversal of this trend in sight.
Hardest hit by desertification is Sub-Saharan Africa, where poverty is more widespread, preparedness for catastrophe is lower, and means for adequately coping with the phenomenon are very weak; two thirds of the arable land will be lost by 2025.The subcontinent needs improved integrated initiatives on local, national und multinational level for a sustainable natural resources management. Environmental Information systems can increase awareness and throw light on decision making processes on the complexity of desertification badly needed by most African countries.
Desertification is nowhere more serious than in the Middle East and North Africa (MENA), stretching from Pakistan in the east to Morocco in the west, and from Ethiopia and Sudan in the south to Turkey in the north. Yet, many MENA countries have successfully rehabilitated large areas. Concerted efforts can indeed stop and even reverse desertification, though their long-term success will depend on how well they manage their limited water resources.
The Millennium Ecosystem Assessment projects that the intensification of freshwater scarcity in combination with continuous water extraction from delicate dryland ecosystems is likely to exacerbate desertification, thus leading to a downward spiral of ecological deterioration and a precarious depreciation of livelihoods in many developing regions. This in turn can push people to migrate, which can have far reaching implications affecting local, regional, and even global political and economic stability.
