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.
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
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
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 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.
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
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 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.
An innovative, low-cost methodology was developed to assess the potential of sites in Tunisia for supplemental irrigation and water harvesting.
This report summarizes results from a large multi-partner project, Integrated watershed development
for food security and sustainable improvement of livelihood in Barani, Pakistan. The project (2007
to 2010) aimed to develop, demonstrate, and evaluate cost-effective technologies for monitoring
