The objectives of this report are to evaluate and test, with community participation; the benchmark water management options which sustainably improve water productivity, net return per water unit, and optimize water use. The strategies evaluated have to be economically viable, socially acceptable, and environmentally sound in the three different agricultural eco-systems.
Few regions present bigger development challenges than the African drylands – home to nearly 300 million people, and the vast majority of Africa’s poor. Food security and rural welfare in these areas are limited by a range of factors, biophysical, socio-economic and policy-related. And many of the biggest challenges – poverty, drought, land degradation, food insecurity – will be exacerbated by climate change.
This publication reviews the historical and current literature on land degradation in Morocco and
presents the results of a case study in the western part of the country. It is intended as a reflection on
the baseline causes for land degradation, so contributing to the development of enabling agricultural
policies and the associated institutional dynamics that are needed to overcome degradation problems.
This report identifies crucial policy inconsistencies and dysfunctions that were, so far, ineffective in
This issue of Caravan describes the new program, and some of the research innovations it will build on. The issue begins with two ‘opinion pieces’ by scientists from partner organizations in the CRP. They share lessons learnt from past successes (and failures), and ideas that could be applied to dryland
Dans le contexte de mettre en œuvre ses engagements dans le cadre de la Convention des Nations Unies sur la Lutte contre la Désertification, le Maroc s’est dote d’un Programme d’Action National de Lutte Contre la Désertification (PANLCD).

Time series of vegetation indices (VI) derived from satellite imagery provide a consistent monitoring system for terrestrial plant productivity. They enable detection and quantification of gradual changes within the time frame covered, which are of crucial importance in global change studies, for example. However, VI time series typically contain a strong seasonal signal which complicates change detection. Commonly, trends are quantified using linear regression methods, while the effect of serial autocorrelation is remediated by temporal aggregation over bins having a fixed width.
The Global Environment Facility (GEF) and the UN Development Programme (UNDP) have published this annual report on joint projects financed during 2011 on ecosystems and biodiversity preservation, green development strategies, and sustainable use of water and ocean resources, among other topics. The GEF financed and supported 323 UNDP projects in 2011.
This regional report by the United Nations Human Settlements Programme (UN-HABITAT) highlights that, although urban slums are decreasing and urban innovations are being introduced, the Arab region still faces major challenges, including high youth unemployment rates and climate change. The report argues that climate change can increase competition over scarce resources, decrease food security, increase poverty and social instability, and accelerate environmental migration and militarisation over natural resources in the area.
