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.

An innovative, low-cost methodology was developed to assess the potential of sites in Tunisia for supplemental irrigation and water harvesting. The methodology, which uses commonly available technologies and information such as remote sensing and a Digital Elevation Model (DEM), was developed and tested using newly constructed hill reservoirs (used to capture surface runoff) and traditional water harvesting systems.

The objectives of this report are to evaluate and test, with community participation; the benchmark water management options which sustainably improve water productivity, net return per water unit, and optimize water use. The strategies evaluated have to be economically viable, socially acceptable, and environmentally sound in the three different agricultural eco-systems.

CropSyst is the crop growth model chosen as a decision tool for the Tadla Benchmark project. CropSyst is a daily time step simulation model. The model was developed to serve as an analytic tool to study the effect of cropping systems management on productivity and the environment. The model simulates the soil water budget, soil– plant nitrogen budget, crop canopy and root growth, dry matter production, yield, residue production, and decomposition. Management options include cultivar selection, crop rotation, irrigation, nitrogen fertilization, tillage operations, and residue management.

The best use of irrigation water is reflected in the strategic approach of the Ministry of Agriculture and the major research objectives of institutions working on sustainable irrigation management. Related research programs can be summarized as follows:
• crop water requirements;
• irrigation techniques, especially surface irrigation;
• irrigation scheduling; and
• soil and water quality as affected by irrigation and drainage.

The literature identifies two common approaches for estimating technical efficiency. One approach is based on non-parametric, non-stochastic, linear programming. This suffers from the criticism that it does not take into account the possible influence of measurement error and other noise in the data (Coelli, 1995). The second approach uses econometrics to estimate a stochastic frontier function, and to estimate the inefficiency component of the error term. The disadvantage of this approach is that it imposes an explicit and possibly restrictive functional form on the technology.

The year 2002 marked ICARDA's 25th anniversary, and coincided with several honors and awards for the center's excellence in research. Research on developing high-yielding kabuli chickpea varieties that thrive in cool, wet winter conditions earned the 2002 King Baudouin Award of the Consultative Group on International Agricultural Research (CGIAR), jointly with the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), which focuses on desi chickpea.

Within the framework of its collaboration with Tunisia, the International Center for Agricultural Research in the Dry Areas (ICARDA), with the financial support of the CRP Livestock Program led by ILRI and the BMZ / GIZ, organized a workshop on "Partnerships to improve pastoral policies in Tunisia". This workshop represents an important step towards a better pastoral policy in Tunisia, by developing strategies for updating the pastoral code aiming at better governance of rangelands.
