THE VISION to forge a global partnership to reverse and prevent desertification/land degradation and to mitigate the effects of drought in affected areas in order to support poverty reduction and environmental sustainability
The Convention offers new hope in the struggle against desertification Over the past decades, the problem of land degradation in dryland regions has continued to worsen. The Convention promotes a fresh new approach to managing dryland ecosystems and - just as important - to managing development aid flows.
La Convention offre de nouveaux espoirs dans la lutte contre la désertification
Le problème de la dégradation des terres dans les régions arides n'a cessé de s'aggraver au cours des vingt dernières années décennies. La Convention propose une manière entièrement nouvelle de gérer les écosystèmes arides et -ce qui n'est pas moins important- les flux d'aide au développement.
La Convención ofrece nuevas esperanzas para luchar contra la desertificación
En las últimas décadas el problema de la degradación de tierras en las regiones de zonas secas ha seguido empeorando. La Convención promueve un nuevo método para gestionar los ecosistemas de tierras secas y administrar las aportaciones de ayuda al desarrollo.
The Kyoto Protocol negotiated in the mid-1990s to address climate change adaptation and mitigation will be replaced by a post-Kyoto agreement in 2012. The new agreement under negotiation needs to seal the policy gaps in adaptation and mitigation that were omitted or excluded from Kyoto on account of scientific uncertainties. Particular attention needs to be given to the potential of land in all its dimensions considering its high capacity to store carbon. Land stores twice as much organic carbon as vegetation and the atmosphere combined.
Drylands have the potential to play a big role in climate mitigation and, in doing so, to deliver significant co-benefits
Until now, the international community has made tireless efforts to get public attention and political action on issues of desertification, land degradation and drought (DLDD) with limited success.
Thus, the mobilization of political will and arousal of public interest and attention around the issue of climate change in particular puzzled activists and decision-makers alike, at least in the DLDD community.
Comme la Préface l’a souhaité, ce document est conçu comme un plaidoyer. Son objectif, en effet, est de montrer pourquoi il faut aujourd’hui replacer la Convention de Lutte contre la Désertification au cœur des stratégies engagées pour affronter la crise montante de l’écosystème global. Son point de départ est un constat sans appel : la progression de la désertification et de la dégradation des terres et des eaux conduisent inéluctablement à un développement non durable (Chapitre I).
Desertification is defined as land degradation in arid, semi-arid and dry sub-humid areas, resulting from various factors, including climatic variations and human activities. More than one third of the surface of the earth consists of drylands. In terms of population, one out of every five people of the world live in already degraded or desertification-prone drylands. These people include many of the world’s poorest, most marginalized, and politically weak citizens. For instance, nearly 325 million people in the African continent live in drylands.
Avant-propos La notion de désertification se définit comme une dégradation des sols en zone aride, semi-aride et subhumide sèche, souvent appelée simplement « zone aride ». On estime qu’elle résulte d’une combinaison de facteurs, parmi lesquels les changements climatiques et l’activité humaine. Plus d’un tiers de la superficie totale de la terre est considéré comme zone aride. En termes démographiques, c’est un cinquième de la population totale du globe qui vit en zone aride déjà dégradée ou menacée de désertification.
La cuenca del río Kilca es uno de los principales sistemas hidrográficos de la región antecordillerana, ubicada en el centro de la provincia de Neuquén. En esta zona, de clima subhúmedo, el uso de suelo dominante es el de "veranada", que consiste en una de las tres etapas anuales de un tipo de ganadería trashumante, basado en el aprovechamiento forrajero de pastizales naturales. Dada la constitución fisiográfica de estos paisajes, existe en ellos una gran propensión al desarrollo de procesos geomorfológicos de erosión y remoción en masa.
Agriculture is vital to the economies of Sub-Saharan Africa: two-thirds of the region’s people depend on it for their livelihoods. Nevertheless, agricultural productivity in most of the region is stagnant or declining, in large part because of land degradation. Soil erosion and soil nutrient depletion degraded almost 70 percent of the region’s land between 1945 and 1990; 20 percent of total agricultural land has been severely degraded. If left unchecked, land degradation could seriously threaten the progress of economic growth and poverty reduction in Africa.
