The Rochester Institute of Technology (RIT), Lake Victoria Fisheries Organization (LVFO), and African Center for Aquatic Research and Education (ACARE) are participating in a Society of the IEEE - Geoscience and Remote Sensing Society (IEEE-GRSS)-funded workshop aimed at enhancing monitoring capacity in the African Great Lakes region The workshop focused on large lake monitoring using remote sensing technology. 

The program invited experts from the ten riparian countries of the African Great Lakes to participate in a short workshop to better understand remote sensing as a technology for monitoring various metrics on lakes.

Participants and guests from thirteen countries, including nine African Great Lakes riparian countries participated in a monitoring workshop. The workshop focused on specific remote sensing monitoring technology and the need for long-term monitoring, both will help better understand the lakes in an ongoing quest to protect them and their valuable resources which provide food, water, transportation and contributes to the GDP of each African country.  Photo taken November 11, 2021, Entebbe, Uganda. 

Workshop Background & Importance

The African Great Lakes provide important ecosystem services to the communities adjacent to the lakes. Among the most important services are fisheries, as a source of protein and a component of food security, and the use of water for drinking and industry. Lake managers need information on lake water status to maintain the fisheries and water quality in the face of increasing demands and threats. Traditional lake sampling from boats can provide researchers with very accurate information, but only at the sample locations. The practical limitations of cost and time prevent traditional sampling from a boat from giving a complete view of large lakes over time and space. Remote sensing can allow researchers and managers to have an expanded view of lake conditions over time and space. In the last few decades, the development of earth observation sensors flying on satellite, aircraft, or drones has enabled new detailed understanding of processes over time and across large lakes, such as water circulation and biological productivity. But making the most of this image sensor data still requires capacity development for the African Great Lakes region.

 

This workshop is motivated by the need to boost remote sensing as a tool within a larger need for long-term monitoring of the African Great Lakes. Remote sensing can provide monitoring data on lake water conditions such as temperature, turbidity, and algae abundance, depending on the type of sensor used to capture the image data. This workshop provided African Great Lakes experts the opportunity to acquire fundamental knowledge of remote sensing techniques for lake water quality, learn about sensors used on the lake to validate remote sensing measurements, and strengthen the network of researchers with interests in applying remote sensing to the African Great Lakes.

Workshop Agenda

Who is involved

Participants

The participants of this workshop are freshwater and large lake experts from the ten riparian countries of the African Great Lakes. The training on remote sensing is to engage the experts in a different approach to monitoring on the lakes, to gain their perspectives on how such technology might be implemented, and to help create a larger, long-term monitoring program (using remote sensing and other technologies) around the African Great Lakes.
