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.

Articles et Livresdécembre, 2011Algérie, Égypte, Iraq, Jordanie, Maroc, Soudan, République arabe syrienne, Tunisie, Afrique septentrionale, Asie occidentaleIn this study, an economic evaluation of water-use efficiency technologies proposed and tested by the agronomic team in the Tadla Irrigated Perimeter was carried out. To capture climatic variability, the analysis was conducted during two contrasting years (dry and wet). Total annual rainfall was 357 mm in 2005/06 (wet year) and 296 mm in 2006/07 (dry year). During the first year, precipitation was well distributed throughout the season. However, the second year was wet at the beginning, dry in the middle and very wet at the end of the season.

The WOCAT-LADA-DESIRE mapping tool is based on the original WOCAT mapping questionnaire (WOCAT, 2007). It has been expanded to pay more attention to issues such as biological and water degradation, it also places more emphasis on direct and socio-economic causes of these phenomena, including their impacts on ecosystem services. It evaluates what type of land degradation is actually happening where and why and what is being done about it in terms of sustainable land management (SLM) in the form of a questionnaire.

LADA (Land Degradation Assessment in Drylands project) is a scientifically-based approach to assessing and mapping land degradation at different spatial scales ? small to large ? and at various levels ? local to global. It was initiated in drylands, but the methods and tools have been developed so as to be widely applicable in other ecosystems and diverse contexts with minimal required adaptation.
