    Tunisie, Afrique septentrionale

    This summary describes the work of the LADA (Land Degradation and Assessment in Dry Areas) project that identifies and describes geographical areas suffering from land degradation in the governorates of Tunisia. Through a comparative study of these areas, it identifies the failures and successes in national efforts to combat land degradation and, therefore, build local community capacity to resist climate change. It is intended for policymakers, donors and other partners and supporters.

    Tunisie, Afrique septentrionale

    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.

    Asie occidentale, Jordanie

    Research on micro-catchment rainwater harvesting techniques by ICARDA and Jordanian
    scientists has led to the establishment of semicircular bunds on contour ridges and furrows
    (using GPS laser-guided Vallerani machine) and runoff strips in two communities of Jordan
    Badia. As an outcome of this research, an effective micro-catchment laser-guided system was
    identified for rainfall harvesting, which has led to improved water availability, increased
    vegetative cover and improved soil health, and provided rural communities substantial sources

    Maroc, Tunisie, Afrique septentrionale

    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.

    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.

    Afrique septentrionale, Tunisie

    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.

    The problem of rangeland degradation can be reversed through revegetation, for example through inclusion of various locally adapted native species in the reseeding. Reseeding is the process by which rangelands are rehabilitated and it has two purposes; to ‘repair’ the degenerated rangeland system, and to increase the forage available for grazing animals. It involves sowing seeds directly into their final growing position, and is applied on rangelands with an advanced degree of degradation, low plant density or poor productivity levels.
