    Land resources are one of nature’s most precious gifts. They feed us and help our societies and economies to thrive. Land resources are one of nature’s most precious gifts. They feed us and help our societies and economies to thrive. Some 2.5 billion agricultural smallholders worldwide manage around 500 million small farms, providing more than 80 per cent of food consumed in Asia and Sub-Saharan Africa. These resources are being degraded at an alarming pace.

    This chapter sets out to present a short review of (i) the general context of land degradation under the framework of UNCCD – the international convention on desertification with a specific focus on Land Degradation Neutrality, and (ii) examples of the main processes responsible for soil degradation (e.g. surface crusting, runoff and water erosion, tillage erosion, wind erosion, and salinization), along with the principles of desertification control and land rehabilitation, in light of the socioeconomic context and ecological conditions and processes.

    Algérie, Maroc, Tunisie

    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.

    Land Use Policy Volume 57

    Publication évaluée par des pairs

    États-Unis d'Amérique

    Farmland ownership fragmentation is one of the important drivers of land-use changes. It is a process that in its extreme form can essentially limit land management sustainability. Based on a typology of land degradation and its causes, this process is here classified for the first time as an underlying cause which through tenure insecurity causes land degradation in five types (water erosion, wind erosion, soil compaction, reduction of organic matter, and nutrient depletion).

    Afrique septentrionale, Égypte

    The overall aim of the project is to identify physical and institutional interventions to improve water management using an integrated approach across scales (from farm to main canal levels) and encompassing water quantity–quality interactions. The project’s geographical focus is the Nile Delta in Egypt.
    The project was originally planned for four years. Due to a policy change announced by the Australian Government in reducing the aid investment in the Middle East and North Africa, including Egypt, the duration of the project was reduced to three years.

    Land degradation is an underestimated global concern with far-reaching
    implications affecting the ability of land to provide food and incomes. Globally, a
    large portion of the vulnerable human populations—the rural poor—live on
    degrading and less-favored agricultural lands without market access.
    Heterogeneous solutions that ensure both economic and environmental
    sustainability are needed at multiple scales.
    On a policy level, awareness of land and soil degradation is increasing. Last year

    Agricultural production systems are a vital lifeline of the rural farming community in Central Asia. However, shrinking natural resource base, increased land degradation and severe irrigation water scarcity render current crop production practices not sustainable as these perform below their potential. Though there is considerable scope for improving productivity through bridging the yield gaps and introducing sustainable land management practices. However crop productivity and production pattern varies across scales, mostly driven by irrigation water availability, markets, and
