    Rangelands in north Africa and the near east in general provide numerous goods and services that have great economic, social, cultural, and biological values. For centuries, inhabitants of rangelands have engineered pastoral and farming systems that have sustained their livelihoods in these harsh and dry environments. Unfortunately, these rangelands have undergone profound socio-economic changes where traditional grazing systems (transhumance and nomadism) which had historically allowed for grazing deferment were abandoned.

    The aim of the project was to develop and implement a web-based GIS tool for defining sustainable
    land management (SLM) options by social-ecological context at global scale. This Global Geoinformatics Options by Context (GeOC) tool aims to support the implementation of SLM practices
    by the international community. The GeOC is designed to provide stakeholders/projects and
    programmes with plausible, robust extrapolation domains for guiding decisions on SLM options,

    In response to the severe economic, social, and environmental costs of degradation across Tunisia’s rangelands, the International Center for Agricultural Research in the Dry Areas (ICARDA) has worked with the General Directorate of Forestry (Direction Générale des Forêts, DGF) to draw up a new pastoral code. This code could facilitate a more sustainable governance regime that also delivers for pastoral communities. Inclusive and practical, the code also offers a framework for other countries experiencing degradation in rangeland areas.

    Soil erosion is a natural process causing serious land degradation problems. In Tunisia, soil
    erosion represents a serious environmental problem. The Rmel watershed located in the
    Governorate of Zaghouan in north-eastern Tunisia and covering an area of 679 square
    kilometers, suffers from this problem. It was thus selected to estimate annual soil loss using the
    Revised Universal Soil Loss Equation (RUSLE), and geographic information system (GIS).
    RUSLE model’s parameters (R, K, LS, C, and P) were derived from digital elevation model

    Double up legumes is intercropping two legumes (in this case groundnut and pigeonpea) that have different growth habits and takes advantages of beneficial interactions of the two legumes on the same piece of land. Intercropping groundnut and pigeonpea using the correct spatial arrangement increase land productivity, provides more types of food and profits while conserving and sustaining the environment through enhancement of soil fertility.

    Stipagrostis pungens is a perennial grass species which belongs to the Poaceae family. It is usually found with several erect culms, grows up to 1.5 m in height, and forms substantial tufts. It is a tall stiff glabrous grass with pungent leaves, and a C4 grass with sclerophyllous, spine-tipped, inrolled leaves, with sunken stomata. The root system extends laterally for a radius of 20 m or more. The roots are covered throughout their length by a sandy sheath, which is penetrated by the root hairs that occur throughout the entire length of the sheath.
