هذه الخطوط التوجيهية هي أول صكّ عالمي شامل خاص بالحيازات وإدارتها يُعدّ من خلال مفاوضات حكومية دولية. وتضع هذه الخطوط التوجيهية مبادئ ومعايير مقبولة دولياً للممارسات المسؤولة لاستخدام الأراضي ومصايد الأسماك والغابات وللتحكّم بها.

The guidelines are the first comprehensive, global instrument on tenure and its administration to be prepared through intergovernmental negotiations.

This issue of Caravan describes the new program, and some of the research innovations it will build on. The issue begins with two ‘opinion pieces’ by scientists from partner organizations in the CRP. They share lessons learnt from past successes (and failures), and ideas that could be applied to dryland

Few regions present bigger development challenges than the African drylands – home to nearly 300 million people, and the vast majority of Africa’s poor. Food security and rural welfare in these areas are limited by a range of factors, biophysical, socio-economic and policy-related.

Remote sensed imagery in combination with secondary agricultural statistic was used to map crop water productivity (WP) in the Nile River Basin. Land productivity and crop tandardized gross value production (SGVP) were calculated at administrative level using the agricultural census data.

Spate irrigation, a floodwater harvesting and management system, has for the past 70 centuries provided a livelihood for about 13 million resource-poor people in some 20 countries. Despite being the oldest, the system still remains the least studied and the least understood.

The CPWF was designed to be different. Developed in response to a call for change in a previous round of Consultative Group on International Agricultural Research (CGIAR) system

reform, the CPWF was intended to foster cross-CGIAR cooperation and find ways to bring in new partners. Over time the CPWF has successfully broadened the CGIAR’s sources of

For over a decade, the globalisation of environmental, economic and social issues has induced rapid modification in agriculture and land. These changes raise the question of future extensive livestock systems in regards to the worldwide challenge to double livestock production by 2050 in ways which are safe for the environment.

We propose a flexible and adaptable framework to assist the quick design of models dealing with the durability of the extensive livestock systems at the territorial scale. This metamodel results from the collaborative design starting from MAS developed on 7 sites in Latin America, France and Senegal. It is composed of four packages: Agent, Community, Space and Vegetation-Herd.
