Restoring Natural Capital in Arid and Semi-arid Regions
Combining ecosystem health with human well-being An ecological and socio-economic need For the last one and a half centuries, humanity has been wantonly eating away at its natural reserves. This situation has lead to two world crises that are intricately connected: An ecological crisis that entails losses in biodiversity and in ecosystem functions at the […]
Publication of “Ecological engineering for sustainable agriculture in arid and semiarid West african regions”
Based on the authors’ and contributors’ experience, West Africa is focused on to illustrate the ecological intensification to agricultural production in the broad sense. Examples from non-African tropical dryland areas worldwide are also discussed to illustrate the potential of agroecological engineering to sustainable land management and therefore to the fight against desertification. Dominique Masse (Agronomy-Ecology, […]
Science and civil society
In the fight against desertification Scientific research in arid areas For a long time, agronomic research has been focused on basic and technical subjects, in view of a linear transfer to the farming world. The model was based on results obtained in station that were communicated to farmers via agents of extension services. This model […]
CARI – Centre d’Action et de Réalisations Internationales (France)
In brief Created in 1998, CARI is an organization for international solidarity or non-governmental organization (NGO) helping African populations in arid areas especially in Sub-Saharan Africa and in North Africa. • It works in fields like rural development and the land degradation control under the desertification and climate change.• It aims to the amelioration of the local […]

Publication of a note on neutrality regarding land degradation in the Sahel through the lens of land tenure issues
Land neutrality, although a sustainable development goal, remains largely unknown outside of international environmental negotiation circles and academic circles dedicated to the subject. For the past 10 years, the United Nations Convention to Combat Desertification has volunteered to implement this goal in the regions under its mandate, namely arid, semi-arid, and dry sub-humid areas. A […]

Biodiversity and land degradation in dryland regions – Importance of agrobiodiversity in oases
Traditional oasis farming systems consist of a palm grove with fruit trees (apricot, pomegranate, etc.), vegetable and/ or fodder crops growing in the understorey thereby forming a rich yet endangered oasis of agrobiodiversity. This agroforestry-based three-storied cropping system accounts for the so-called ‘oasis effect’, i.e. creation of a microclimate conducive to agriculture. Date palms filter […]
Ecological engineering
For sustainable agriculture in arid and semiarid West African regions Rethinking management of agricultural and natural systems through ecological engineering Arid and semiarid West African regions are characterized by heavy environmental constraints that have shaped natural ecosystems and human activities: low, infrequent, irregular, unpredictable rainfall concentrated within a period of a few monthssoils mainly with […]
Fighting wind erosion
One aspect of the combat against desertification Wind erosion, a complex mechanism that degrades the environment Wind erosion is one of the most traumatic aspects of the desertification process. It leads to severe degradation of the environment, impoverishing soil as vast quantities of particles are carried away by the wind. It can be hard to […]
