OSS has made a substantial contribution to the design and development of monitoring-evaluation systems for tracking the implementation of the United Nations Framework Convention to Combat Desertification. This has earned OSS the title of reference center for the North Africa countries. The Organization’s technical and methodological achievements helped the countries of its zone in the identification, calculation and interpretation of impact indicators.

OSS achievements and experience have been adapted and valorized for other environmental conventions and action programs related to climate change and biodiversity in particular. The Afromaison project’s results are a perfect illustration of this approach.

OSS continues to play a major role on issues related to monitoring-evaluation and is involved in most of the initiatives and programs that concern its zone of actions. For instance, OSS has contributed to the identification of Land Degradation Neutrality (LDN) indicators and the definition of approaches for their calculation.

In the framework of the BRICKS project, OSS has developed several tools and methodologies for the monitoring-evaluation of the SAWAP program, which covers 12 Sahelian countries (Benin, Burkina Faso, Chad, Ethiopia, Ghana, Mali, Mauritania, Niger, Nigeria, Senegal, Sudan and Togo) in support to the Great Green Wall). The monitoring indicators developed cover a wide range of aspects related to areas under Sustainable Land Management, carbon sequestration, livelihoods improvement, etc.
