Abstract
To ensure the long-term sustainable use of African Great Lakes (AGL), and to better understand the functioning of these ecosystems, authorities, managers and scientists need regularly collected scientific data and information of key environmental indicators over multi-years to make informed decisions. Monitoring is regularly conducted at some sites across AGL; while at others sites, it is rare or conducted irregularly in response to sporadic funding or short-term projects/studies. Managers and scientists working on the AGL thus often lack critical long-term data to evaluate and gauge ongoing changes. Hence, we propose a multi-lake approach to harmonize data collection modalities for better understanding of regional and global environmental impacts on AGL. Climate variability has had strong impacts on all AGL in the recent past. Although these lakes have specific characteristics, their limnological cycles show many similarities. Because different anthropogenic pressures take place at the different AGL, harmonized multi-lake monitoring will provide comparable data to address the main drivers of concern (climate versus regional anthropogenic impact). To realize harmonized long-term multi-lake monitoring, the approach will need: (1) support of a wide community of researchers and managers; (2) political goodwill towards a common goal for such monitoring; and (3) sufficient capacity (e.g., institutional, financial, human and logistic resources) for its implementation. This paper presents an assessment of the state of monitoring the AGL and possible approaches to realize a long-term, multi-lake harmonized monitoring strategy. Key parameters are proposed. The support of national and regional authorities is necessary as each AGL crosses international boundaries.

Funding Information:Many thanks to all AGL experts, particularly from AGL countries, who contributed with ideas and other information during discussions to develop a harmonized long-term multi-lake monitoring proposal. We also thank the ACARE and the IISD for supporting this work and a preparatory survey. The setting up of a network of advisory groups at each lake by ACARE and the IISD has greatly facilitated the preparation of the present proposal.
Funding Information:
The proposed harmonized long-term monitoring of the AGL is closely linked to the blue economy principles whose development is supported by the African Union Inter-African Bureau for Animal Resources (AU-IBAR), a technical office of the Department of Rural Economy and Agriculture of the African Union Commission. Blue Economy constitutes the Goal 6 of the Agenda 2063 and Goal 14 of the UN Agenda 2030 ( AU-IBAR, 2019a ). The establishment of monitoring and information systems for inland waters is one of the main objectives of the blue economy strategy ( AU-IBAR, 2019b, AUC-NEPAD, 2014 ). National and regional policies and strategies are expected to provide for information sharing between national agencies and between countries ( AU-IBAR, 2015 ).
