OPIDIN has been developed through close cooperation between the Direction Nationale de l'Hydraulique, Wetlands International Mali and Altenburg & Wymenga ecological consultants, with the support of the Dutch embassy in Mali. Starting with the analysis of water levels and the construction of a forecast model in 2009, the tool was continuously improved and transformed into a practical tool for predicting water levels in the Inner Niger Delta.

Direction Nationale de l'Hydraulique (DNH) is in Mali part of the Ministry of Energy, Mines and Water and responsible for management and regulation of the water regime in Mali. DNH manages the daily water level measurements at some dozens of hydrometric stations in Mali.

Wetlands International
Wetlands International is the only global non-profit organisation dedicated to the conservation and restoration of wetlands.  Within Mali, Wetlands International maintains a country office in Bamako and in Sévaré. It has effectively managed several projects across West Africa, including within the Upper Niger and Inner Niger Delta.

Altenburg & Wymenga ecological consultants
Altenburg & Wymenga (A&W) are private sector ecological consultants skilled in strategic ecological assessment and in environmental management, with extensive experience in West Africa including Mali. A&W made the site and is responsable for the analysis of the data and management of OPIDIN.

Frerotte-Hydro-Consult is a private consultant involved in IWRM aspects in the upper Niger basin in Mali and in Guinea; he provided support to the Embassy of NL for their water and food security programme and was involved in the identification and the development of OPIDIN.

Financial support

This study was made possible by the Dutch Embassy in Mali who supported - since the very beginning - the idea to create a tool like OPIDIN, and provided funds for the development, the testing phase and the installation of the tool.

The study could built upon earlier work. A preliminary version of OPIDIN was developed in 2009 in the framework of Projet PvW 07012 (Mali): Gestion intégrée des ressources en eau dans le bassin du Niger en amont de Taoussa – Outil d’aide à la decision, a study financed by ‘Partners for Water’, a joint initiative of six departments of the Government of the Netherlands. The study got a follow-up in 2010 in the framework of Wetland & Livelihoods Project: GIRE (Gestion integrée de resources naturelles) dans le bassin du Niger en amont de Taoussa, a project of Wetlands International. OPIDIN was further elaborated in the framework of Afromaison.
