Contact National Representatives

Countries with ten or more SIL members are entitled to elect a National Representative (NR). NRs are elected for three-year periods. They assist the General secretary-Treasurer in collecting annual dues from members of their country in their own currency and transferring the total amount to SIL’s bank account.

I see SIL, with its broad representation from countries all over the world, as the ideal organisation to support international collaboration among limnologists. As Swiss SIL representative I want to continue what I do in my work: integrate science and practice. Water is a very valuable good which is under threat even in Switzerland, as witnessed by ongoing discussions on, for instance, micropollutants or whether lakes are now "too clean." With my contacts within Switzerland and abroad I hope to connect colleagues in such discussions.
