This note summarizes the results obtained from available documentation and consultations with key experts and practitioners. It draws lessons from past experiences while considering current development needs. The Great Green Wall Initiative, has not been conceived as a wall made up of trees planted across the Sahara, but rather as a set of cross-sectoral actions and interventions aimed at the conservation and protection of natural resources with a view to achieving development and, particularly, alleviating poverty.

The long term ecological surveillance observatories network (Réseau d'observatoires de surveillance écologique à long terme, ROSELT/OSS) of the Sahara and Sahel Observatory (OSS) consists of a cluster of observatories which span circum-Saharan Africa and share a common focus on the issue of desertification. Since its inception, the network has been addressing the challenge of improving the collective knowledge on desertification; a scourge that has complex linkages with the issues of biodiversity and climate change.

Over the last ten years, OSS has put in place standardised protocols of data collection and processing in the circum-Sahara with a view to apprehending the trends characterising the evolution of the ROSELT/OSS observatories’ ecological and socio-economic systems. In this part of Africa, where rainfall decrease is chronic in the Sahel and spreading to North Africa, population growth and land use change—due to overgrazing or the conversion of rangelands into croplands—have adverse impacts on the environment. In addition, sand encroachment constitutes a serious threat to irrigated farmland. Biodiversity is equally affected, as several species face the danger of extinction due to human activities.

In the south of the Sahara, natural resource depletion is often among the causes for migration towards the zones where climate and life conditions are more favourable. This forced displacement is significantly less severe in the north of the Sahara where policies put in place by governments in the sub-region encourage sedentary lifestyles.

Based on the scientific reports of the ROSELT/OSS observatories, this publication provides an overview of the data management systems and the decision-support tools developed across the ROSELT/OSS network. It also highlights difficulties pertaining to environmental surveillance in North and West Africa.

The Transboundary Diagnostic Analysis recommended by the Global Environment Fund has been applied to transboundary waters of the Iullemeden Aquifer System (IAS) shared by Mali, Niger and Nigeria. It allowed identifying three major transboundary risks namely (1) the reduction of resource availability, (2) degradation of water quality, and (3) the impact of variability / climate change.

Recognizing the need for a regional approach for shared groundwater management to face those transboundary risks for which efforts of one country cannot find a sustainable solution, the three countries committed themselves in a process of joint water resources management. Through this process, they plan to mitigate the negative impacts of these risks on their shared groundwater resources.

Through this process, policy and strategy elements for mitigating these risks have been developed as well as communication tools in order to promote an early warning system, a participatory approach to better manage these risks, and finally a mechanism for monitoring transboundary water resources. A Memorandum of Understanding with its roadmap was adopted by the three countries for establishing a consultation mechanism, a legal consultation for a joint management and equitable and rational of their common resources.

Through this process, they plan to mitigate the negative impacts of these risks on their shared groundwater resources.

The policy and strategy elements to mitigate these risks have been designed to help countries in formulating their policies and strategies accompanied by an action plan in the medium and long term. These elements include the political, socio-economic and environmental dimension. They were developed by conducting the analysis of solutions for each risk examined according to (a) hydrogeological and environmental (b) socio-economic, and (c) legal and institutional dimensions.

To develop this policy at regional level, national legislation on water should be updated taking into account the achievements of the project in terms of the methods and management of transboundary groundwater regimes.

The Transboundary Diagnostic Analysis recommended by the Global Environment Fund has been applied to the transboundary groundwater of the Iullemeden Aquifer System shared by Mali, Niger and Nigeria. The Transboundary Diagnostic Analysis is a scientific and technical fact-finding analysis based on technical and scientific information available and verified, to examine the state of the environment and the causes of its degradation, focusing on transboundary problems without ignoring national concerns and priorities.

Three major transboundary risks were identified: (1) reducing the availability of the water resource, (2) degradation of water quality, and (3) the impacts of climate variability/change. This required the development of a database with more than 17000 water points, a Geographic Information System and a mathematical model. This model has among other things, highlighted the overexploitation of the resource since 1995 and the interconnection between the Niger River and the aquifers. The immediate, root and underlying causes (including the governance of water) of these risks were analyzed.

The Transboundary Diagnostic Analysis is a participatory approach involving all stakeholders concerned with the issue. To this end, it contributes to strengthen solidarity and confidence between them.
