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 rangelands of West Asia and North Africa are the grazing grounds for the Bedouin with their flocks of sheep, goats and camels and are known as al Badia in the Middle East region. Average annual rainfall in the Badia ranges between 50 and 250 mm (Haddad 2006). Despite its scarcity, rainwater is generally poorly managed and much of it is lost through runoff and evaporation. To improve production in hese areas, there is a need for the sustainable management of natural resources – land and water (FAO 1983).

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.

Implementation of land management policies influences land use and hence
causes environmental change. Taking the Ordos rangelands in China as a case
study, this paper explores the potential of remote sensing to assess in dryland
areas the impacts of policies on the environment. Thirteen Landsat images of the
period 1978 2010 were acquired and those corresponding to the starting dates of
implementation of different policies were selected for land-cover change analysis;
others were used to check the detected change and track the normalized -

This laboratory manual of analytical methods has been compiled to be used primarily by research
assistants, technicians and student trainees working in the laboratory. The methods have been
selected from different sources and adapted for routine analyses in the WANA region. A detailed
description of the methods can be found in the original publications listed in the references. As
analytical techniques are developed and improving, this manual will be subject to continuous
revision. Any helpful suggestion and feedback from users is most appreciated. -

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.

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.
