    Algeria, Morocco, Tunisia

    States of ecological maturity and temporal trends of drylands in Morocco, Algeria and Tunisia north of 28 N are reported for 1998–2008. The input data were Normalized Difference Vegetation Index databases and corresponding climate fields, at a spatial resolution of 1 km and a temporal resolution of one month. States convey opposing dynamics of human exploitation and ecological succession. They were identified synchronically for the full period by comparing each location to all other locations in the study area under equivalent aridity.

    MENA’s permanent cropland – currently at less than 6% of the total land area – is shrinking due to serious land degradation and recurrent droughts. The region faces the most severe water shortage in the world with annual renewable water resources per capita estimated to decline from 1,045 m3/yr in 1997 to 740 m3/yr in 2015.

    Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled. That’s why the UN General Assembly declared 2015 as the International Year of Soils. And the good news is that this new report shows that while Africa remains the most severely a«ected region, the benefit of taking action across the continent outweighs the cost of implementing it: not just by a little, but by a factor of seven.

    Around 2.5 billion people – 30 percent of the world’s population – live in the dry areas, which cover more than 40 percent of the world’s land surface. Scarce natural resources, land degradation and frequent droughts severely challenge food production in these areas. Both North Africa (Morocco, Algeria, Tunisia) and the North East of Brazil fall under arid and semi-arid climate. Cacti have developed phenological, physiological and structural adaptations for growth and survival in arid environments where they have multiple functions (food, feed, soil conservation, etc.).

    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

    A tragedy of the commons is unfolding in the rangelands of West Asia and North Africa (WANA), where land is either public or collectively owned. Overgrazing under this land tenure has led to severe land degradation and soil erosion. Poverty and environmental degradation are intertwined in this low-rainfall region, where more than 38 million people live in rural areas and depend mainly on agriculture. Traditional rangeland grazing provides fodder in winter and spring, while in summer and autumn the animals browse cereal stubble and other crop residues.

    With current rates of land degradation reaching ten to twelve million ha per year, there is an urgent need to scale up and out successful, profitable and resource-efficient sustainable land management practices to maintain the health and resilience of the land that humans depend on. As much as 500 million out of two billion ha of degraded land, mainly in developing countries, have restoration potential, offering an immediate target for restoration and rehabilitation initiatives.1 In the past, piecemeal approaches to achieving sustainable land management have had limited impact.

    Atriplex nummularia has been extensively planted in Northern Africa to combat desertification. However, few studies evaluated the effectiveness of these interventions. This study aimed at assessing the dynamic performance of a number of Atriplex plantations located in the Marrakech province in terms of multitemporal dry biomass production. Three SPOT 5 images (2004, 2008 and 2012) and field biomass measurements were integrated to quantify the dry biomass production dynamics of plantations established from 1996 to 2007. Different plant ages covered the whole plant life cycle curve.
