Great Lakes of the World (GLOW)

            GLOW is a continuing series of international symposia organized by AEHMS in order to promote interaction and communication between Great Lakes scientists and communities across the world. The purpose of GLOW is to establish a platform where understanding of structure, function and performance of healthy and damaged ecosystems from integrated, multi-disciplinary and sustainable perspectives is promoted.



            GLOW I was held in Zimbabwe during 1996. This modest but rewarding beginning resulted in a special issue of the society’s journal, Aquatic Ecosystem Health and Management (Munawar, 2000) and a peer-reviewed book (Munawar and Hecky, 2001). Subsequently GLOW II convened in Sligo, Ireland, and played a significant role in bringing researchers of Great Llakes together. For the first time, significant numbers of Great Lakes scientists from Africa, Europe and North America were brought together. AEHEM published another special issue devoted to GLOW II (Munawar, 2002).

            The third GLOW International Conference, Comparing Great Lakes of the World- Climate, Food-webs, Biodiversity and Integrated Management: GLOW III, was held in Arusha, Tanzania in 2002. The participants discussed the need for management of the world’s Great Lakes, particularly those in Africa. It was unanimously recognised that the primary goal in developing countries and especially in Africa was primarily to sustain fish yield in order to guarantee food security and poverty alleviation. Management is also needed to prevent or resolve conflicts over fishing grounds, methods and the fish trade (Munawar, 2003).

            Since the Symposium on Resource Use and Conservation of the African Great Lakes, which was held in Bujumbura, Burundi, in 1989, new information about the state of Lake Tanganyika has been scarce. The fourth GLOW symposium offers a unique opportunity to review and evaluate progress made on Lake Tanganyika as a case study and other Great Lakes in general. Lake Tanganyika constitutes an important source of income, employment, drinking water and food for a multitude of people living on or near the lake. Despite increased human pressure on these resources, sustainable development needs to be ensured and brought about by effective environmental and fisheries management, on the basis of adequate legislation and policy making. Our challenge is to convince the relevant authorities that the health of Lake Tanganyika’s ecosystem is the key element in the sustainability of the resource use and a prerequisite for both human health and development.

            This is an opportune time to meet in Africa since various national and international projects on the African Great Lakes are starting up or ending (FAO, ADB, EU, IUCN, GEF, FINNIDA, etc.) and therefore new, interesting results and emerging management issues may be presented.

            The Symposium plans to focus on a variety of timely topics and themes relevant to Great Lakes of the Wworld, large lakes in general and Lake Tanganyika in particular. We invite active and interested participants to attend GLOW IV to present papers or posters on various aspects of Great Lakes/Large Lakes research as highlighted below:

·       Climate change,

Venue and climate:

The conference will be held at a luxury hotel in Bagamoyo, north of Dar es Salaam, an ideal venue on the tropical coast of the Indian Ocean, where one can enjoy the oceanic breeze under the famous African palm trees.


Travel Information:

KLM-Air France operates daily flights from Amsterdam to Dar es Salaam International Airport. Also Swiss and British Airways connect Europe with the capital city of Tanzania. How to reach Nanjing, name of international airport, major airlines serving Nanjing, transportation options (from airport to hotel etc.), prices, etc. The GLOW Organizing Committee will arrange for transportation from the airport to the hotel.



Pre and Post Conference Tours:

Some suggestions (with costs) which will be paid by the participant if they want to go. For example, one day field trip to see ecological and conservation areas. Dar es Salaam is a good starting point for excursions to the Selous Game Reserve, the spice island Zanzibar, and of course the many other National Parks in Tanzania. The Local Arrangements Committee will be organizing one or more tours closer to the Conference date.
