    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

    Maroc

    This paper presents and analyses land use changes in the periurban areas of Meknes, Morocco, focusing on disappearing fertile and productive farmland. Although identified by the Moroccan public policies, the concern for periurban farmland protection is not the government's first priority. It remains behind economic development and housing of low-incomes. In Meknes, where land tenure remains very complex, urban growth is impacting high-quality-soil farmland while the land market is characterised by increasing farmland values and weak public policy regulation.

    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.

    This volume examines and evaluates the impact of international statebuilding interventions on the political economy of conflict-affected countries over the past 20 years. It focuses on countries that are emerging, or have recently emerged, from periods of war and protracted conflict. The interventions covered fall into three broad categories:

    Sacred sites are of conservation value because of their spiritual meaning, as cultural heritage and as remnants of
    near-natural biotopes in landscapes strongly transformed by man. The vegetation of sacred sites in Morocco was
    studied recently. Information about their number, spatial pattern or relief position is fragmentary. However, these
    parameters are important to evaluate their role as refuge for organisms and their representativeness of potential
    natural vegetation.

    When discussing water and sanitation issues, technology is often seen as the key element by many stakeholders. Within a multinational project, the opportunity was taken to analyse the experiences with the existing water infrastructure to look behind this assumption and - if not working satisfactory - to identify the key requirements that obviously have not been met. Following this, it should be possible to prepare a set of requirements to learn from this.

    In this paper, existing wastewater treatment practices in 7 African countries, i.e. Algeria, Burkina Faso, Egypt, Ghana, Morocco, Senegal and Tunisia, are reported. Data were collected by questioning wastewater treatment plants managers as well as treated wastewater users in 2012. This study showed that 0.2 to 63 L/d/person of wastewater are treated in these countries, with the higher levels obtained for North Africa.

    This study aimed to evaluate the impact of climate change on the geographical distribution of selected native species from two areas from West Asia and North Africa. Three species representing two genera were selected for assessment of their vulnerability to climate change. The first species was Salsola vermiculata L. which is common to both study areas. The second genus was represented by two species, Haloxylon salicornicum (Moq.) Bunge from the Syrian rangelands and H. schmittianum Pomel from southern Tunisia.

    To ensure a food-secure future, farming must become climate resilient. Around the world, governments and communities are adopting innovations that are improving the lives of millions while reducing agriculture’s climate footprint. These successful examples show the many ways climate-smart agriculture can take shape, and should serve as inspiration for future policies and investments.

    Woody biomass production is a critical indicator in evaluation of land use management and the dynamics of the global carbon cycle (sequestration/emission) in terrestrial ecosystems. The objective of the present study was to develop, through a case study in Sudan, an operational multiscale remote-sensing-based methodology for large-scale estimation of woody biomass in tropical savannahs. Woody biomass estimation models obtained by different authors from destructive field measurements in different tropical savannah ecosystems were expressed as functions of tree canopy cover (CC).
