The 31st Congress of the International Limnological Society (SIL) was recently held at the Cape Town International Convention Centre (CTICC).

Prof. Johan Grobbelaar from the Department of Plant Sciences at the University of the Free State (UFS), who is also the chairperson of the local organising committee (LOC), worked hard for six years to secure the bid to host the congress in South Africa. The LOC consisted of Prof. Grobbelaar, Prof. Brian Allanson, Prof. Jenny Day, Dr Carin van Ginkel and Dr Mike Silberbauer.

SIL was founded in 1922 to further the study and understanding of all aspects of limnology, the science of inland aquatic ecosystems and their management.

Congresses are held every three years and this was the first time that SIL met on the African continent.

Almost 400 delegates from 42 countries attended this congress where the state of the science of limnology was presented with two keynote speakers, six plenary lectures, 230 oral and 76 poster presentations, mostly running in five parallel sessions. Exhibitions displayed some of South Africa’s role players as well as the latest equipment from abroad. Delegates could also join pre- and post-congress excursions and the new SIL journal, Inland Waters, was launched at the congress.

Many of the presentations dealt with water as a limited resource, pollution problems and the impact of climate change. The congress resolved that SIL would play a more prominent role in creating awareness of problems impacting on inland waters and also afforded solutions. The 32nd SIL congress will be held in Budapest, Hungary in 2013.
