    Somalia

    Soil loss is a major concern for land managers due to its influence on biomass production, surface water quality and landscape beauty. In Somalia, the risk of soil loss is accelerated by the removal of vegetation, bad land use practices and negative impacts of urbanization. The political upheavals and consequent insecurity in the country are major limitations for detailed database and research in soil loss.

    An assessment of sensitivity to land degradation has been carried out in the Extremadura region, SW Spain, by means of a modelling approach developed by the European Commission funded MEDALUS project (Mediterranean Desertification and Land Use) which identifies such areas on the basis of an index (Environmentally Sensitive Area index, ESA index) that incorporates data on environmental quality (climate, vegetation, soil) as well as anthropogenic factors (management).

    The International Commission on Irrigation and Drainage (ICID), a global network organization with 106 member countries in its fold, is dedicated to the promotion of best practices in water for agriculture, and addresses water supply and management for food production, including drainage and flood control. While striving to improve water and land management, and enhancing the world supply of food and fibre, ICID takes on board environmental concerns and seeks sustainable solutions.

    The coastal zone comprises only 3% of the earth's surface, but contains a disproportionately high amount of its assets. Tidal areas include all those coastal areas where the tidal processes are capable of affecting man's activity or of being influenced by man. Tidal areas differ greatly depending on their location, geophysical conditions, climate, tidal range and cultural differences. Throughout the world, tidal areas have been and are being developed. These developments will continue as food production will need to be doubled in the next 25 years.

    Three smallholder villages located in typical communal (from 1948), old (1987) and new (2002) resettlement areas, on loamy sand, sandy loam and clay soils, respectively, were selected to explore differences on natural resource management and land productivity. Focus group discussions and surveys were carried out with farmers. Additionally, farmers in three wealth classes per village were chosen for a detailed assessment of their main production systems.

    Algeria, Morocco, Africa

    The design of public policy related to irrigation sectors in North Africa was often based on the state view. Local farmers' organizations, made up of family farms, did not contribute to building the legal framework, which was in turn unable to propose specific solutions for family farming. Legal reforms currently underway in Morocco and Algeria show how difficult it is to integrate field realities. Access to land and water resources is often obtained through informal local coordination modes.

    There is an increasingly well-founded understanding of the chief drivers and constraints to widespread adoption by Australian landholders to practices to manage dryland salinity. However, each specific situation depends on a range of biophysical, social and economic factors. Such is the case in this study that examines farmers' salinity management in the Wallatin-O'Brien catchments in the low-medium rainfall zone of the Western Australian wheatbelt.

    Central Asia

    Based on soil characteristics, watertable level, mineral composition of plant biomass, morphological/reproductive traits and carbon discrimination values, a new concept for the classification of halophytes was developed. Six main groups of halophytes have been described within the desert flora of Central Asia. Significant changes on chemical contents of ions: Cl⁻, SO₄ ²⁻, HCO₃ ⁻, Na⁺, K⁺, Ca²⁺ and Mg²⁺among 23 studied halophytic forage species were revealed.

    Kenya

    This study aims to document various community efforts in land rehabilitation and assess their potential. Data were captured using interviews and focus group with 150 community members. A public participation index was used to establish the extent of community efforts in land rehabilitation. The study revealed that in the absence of proper management and dune stabilisation, large areas covered with mobile sand dunes continue to be a threat to grazing lands in northern Kenya. In recognition of this threat, the people of North Horr have launched several initiatives to contain the problem.

    Recent increase in atmospheric concentration of CO₂ and decrease in land-based sink capacity are attributed to numerous anthropogenic activities including increase in severity and extent of soil degradation and desertification. There is a strong link between desertification and global warming with positive feedback of mutual reinforcement. The biophysical process is also driven by social, economic, political, and cultural factors such as overgrazing by local Bedouin population.
