La dégradation des terres s’accélère en Afrique, compromettant le développement économique et social des pays et la sécurité alimentaire d'une population croissante. Elle est provoquée par des causes multiples parmi lesquelles le changement climatique, avec son lot de phénomènes extrêmes tels que les sécheresses et les inondations. De plus, elle est aggravée par des facteurs anthropiques, à l’instar des pratiques agricoles, des pressions urbaines, de la pollution, de la déforestation et de la surexploitation des ressources naturelles.
See the detailsThe year 2023 was marked by the Sahara and Sahel Observatory celebration of the world days of interest thanks to thematic articles written by its experts and disseminated on its website and its social networks. These articles aim to identify environmental issues in relation to the African context, popularize the various subjects covered and come up with recommendations likely to lead to solutions to the various challenges facing the continent. This collection aims to highlight these contributions and draw up an annual report on a wide range of environmental subjects.
See the detailsAgriculture is a key contributor to food security and the economy in Africa. In a context of climate change and variability, accurate, early and spatially referenced agricultural information, has become vital for decision-making. Their production and dissemination is a real challenge that the relevant authorities must take on in order to provide the various stakeholders (decision-makers, planners, researchers, producers, exporters, etc.) with reliable agricultural data and information.
See the detailsLThe international community is increasingly concerned with the relationship between global migration flows and environmental disturbances, including the degradation of ecosystems and the effects of climate change. Indeed, this relationship has been proven and the links between these two phenomena have become a major political issue on a planetary scale. With a growing world population and deteriorating environmental conditions, the challenges related to migration are likely to increase in the years ahead of us.
See the detailsThe present advocacy was developed by the Sahara and Sahel Observatory (OSS), in collaboration with the French Development Agency (AFD), as part of their joint capacity and knowledge building actions, and aims to support decision-makers in understanding the adaptation concept besides its relevance in combating the climate change effects. It precisely focuses on how adaptation measures could impact ecosystem restoration in the Maghreb and Sahel regions.
See the detailsThis work comes after two previous editions of monographs on water resources published by the Sahara and Sahel Observatory in 1995 and 2001.
It is a summary of useful data and information for decision-makers and managers, but also to every single person interested in water issues.
It also provides avenues for reflection and guidance to the different and relevant operators, in order to improve the management and development of water resources, in the area of intervention of the Sahara and Sahel Observatory.
See the detailsGiven the commitments relating to the Convention on Biological Diversity (CBD), the management of ecosystems and the protection of biodiversity have come to the forefront of political concerns. As a result, the international community has declared 2021-2030 the "Decade on Ecosystem Restoration".
See the detailsThis Atlas includes land cover maps of Algeria, Egypt, Jordan, Morocco, and Tunisia. It is intended to decisionmakers, development partners and the general public.
Through some fifty maps and a brief multi-thematic explanation, this Atlas aspires to highlight the linkages between ecosystem services and populations livelihoods in desert areas and their potentialities.
The reader will also find illustrations about the major ecosystems of the project area and their role in transboundary cooperation and socio-economic development to address global changes.
See the detailsAfrica's diverse and rich ecosystems provide services that are essential to sustaining life. Their management is now at the heart of political issues. The economic, social and environmental value of ecosystems have come to the forefront of the collective consciousness.
