    Maroc

    A partir de l’année 2004, l’Etat marocain a décidé de concéder son patrimoine foncier à des promoteurs privés dans le cadre d’un partenariat public-privé. Une dynamique de privatisation et d’appropriation est lancée à laquelle participent des acteurs privés nationaux et étrangers et offre un bon exemple du phénomène d’accaparement des terres.

    Food aid is a critical component of the global food system, particularly when emergency situations arise. For the first time, we evaluate the water footprint of food aid. To do this, we draw on food aid data from theWorld Food Programme and virtual water content estimates from WaterStat. We find that the total water footprint of food aid was 10 km3 in 2005, which represents approximately 0.5% of the water footprint of food trade and 2.0% of the water footprint of land grabbing (i.e., water appropriation associated with large agricultural land deals).

    Land degradation is increasingly recognised as global challenge and is even pushed for as candidate for a (post-2015) Sustainable Development Goal (SDG). The ‘quality of soil’ has been linked to the emergence of conflict, inter alia since it aggravates food and water scarcity. It is an underestimated, but essential element in the nexus of global challenges related to food, water and energy. This Clingendael Report, finds, amongst others, that accurate assessments on land degradation and efforts to restore lands are still lacking to date.

    Land degradation occurs in all continents and affects the livelihoods of millions of people, including a large proportion of
    the poor in the drylands. Opuntiaficus-indica (L.) Mill. is a xerophytic cactus species, widely cultivated in arid and semi-arid regions
    worldwide. As most of species of the Cactacee family, 0. fiCUS-indica exhibits Crassulacean Acid Metabolism (CAM), with
    nocturnal stomata opening and C02 uptake occurring, typically, from dusk to dawn. Many reasons may account for the great interest

    Égypte

    Since the 1990s, the Egyptian government has embarked on two national projects on settlement and agricultural development in the Western desert in preparation for expected future population growth. One of them is the Toshka irrigation project, which carries water from Lake Nasser through the depression of El Kharga towards Farafra Oasis. Another is the East Oweinat project, which has enlarged agricultural land in the south of the Western desert by developing water resources from underground aquifers of Nubian sandstone.

    Soudan

    Sudan experiences one of the most severe fissures between society and territory in Africa. Not only were its international borders redrawn when South Sudan separated in 2011, but conflicts continue to erupt over access to land: territorial claims are challenged by local and international actors; borders are contested; contracts governing the privatization of resources are contentious; and the legal entitlements to agricultural land are disputed.

    Sustainable development of pastoral and agro-pastoral systems, dominated by collective and/or tribal ownership of rangelands, is a key issue for the West Asia and North Africa region. These two systems are located in arid and semi-arid areas and are increasingly threatened by desertification process. The policy responses to tackle this complexity have been a sectorial and fragmented, “top-down” approach, putting forward technical solutions and neglecting the social context.

    In Africa, where most agriculture is rainfed, crop growth is limited by water availability. Rainfall variability during a growing season generally translates into variability in crop production. While the seasonality of rainfall in the drier rangelands can play a significant role in productivity, rain-use efficiency (RUE)—the amount of biomass produced (in kilograms of dry matter per hectare) per millimeter of rainfall—also drives production.

    Background: Even though Plasmodium vivax has the widest worldwide distribution of the human malaria species and imposes a serious impact on global public health, the investigation of genetic diversity in this species has been limited in comparison to Plasmodium falciparum. Markers of genetic diversity are vital to the evaluation of drug and vaccine efficacy, tracking of P. vivax outbreaks, and assessing geographical differentiation between parasite populations._x000D_
