During the last two decades, the Tunisian government has engaged in a vast program for the conservation and mobilization of natural resources. In the Jeffara region, which encompasses the study site, huge works for soil and water conservation (water harvesting) have been implemented whose immediate effects are visible but their efficiency in both the short and the long term need to be assessed and evaluated in detail (De Graaff J. and Ouessar M., 2002).

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.

In the Mediterranean mountain areas of NW Syria, land degradation is a serious problem (Masri et al, 2005). Olive orchards dominate the landscape in Afrin area, and olive oil represents the most important cash income source for rural communities in this area. However, olive yields in many orchards have been decreasing steadily over the last 20 years. Low return to labour has resulted in livelihood insecurity, increased reliance on off-farm labour, and out-migration.

Many efforts have been invested in the Dry Areas to combat land degradation and desertification. Different strategies and approaches for conserving soil and water and restoring degraded lands have been developed by local, national and international agents to synergise efforts towards land degradation neutrality achievement. Tunisia is a dryland country facing a high risk of land degradation over more than 50% of its territory. It is a country with high investment programs for soil and water conservation (SWC), and large level adoption of SLM practices.

The world is witnessing a period in its history when the increasing socio-political upheavals are taking the lives of thousands, and destroying the natural wealth of our planet. Poverty and food insecurity are two key forces driving this destruction. These ongoing problems compound those already being posed by an increasing shortage of water, scarcity of productive land, an expanding population, and the threat of global warming.

Irrational water use and mismanagement are at the root of several environmental problems in the Aral Sea Basin, including secondary salinization. Pre-season leaching (February-March) is a common practice of farmers to manage soil salinity challenges. For example, farmers in the Khorezm region tend applying up to 600 mm of leaching volume to prevent accumulation of salts in the root-zone. However, excessive leaching volume causes the water tables to rise at 1-1.5 m depth which are dangerous depths.

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.
