1999 I got a post-doc scholarship from the Swedish Royal Academy of Sciences, allowing me to move to South Africa and start as a post-doc with the University of the Witwatersrand (Wits) in Johannesburg. My studies focused on the Okavango swamps in Botswana, but also other regional wetlands. I stayed at Wits for two years, and also worked for a few months with the tourist industry in the Okavango.

I have since then used my data and knowledge about the Okavango in many other studies, including my efforts in mapping and monitoring global tropical wetlands and peatlands.

I worked with tourist industry in the Okavango, training the guides in the geological and sedimentological processes sustaining the Okavango. I also developed a web-based and interactive map interface using google maps for the tourist industry, and I created and led training sessions in using geoinformatics.
