History
ST was initiated in 1991 by three University of Botswana Lecturers, due to a concern about the state of Gaborone's environment. These lecturers operated ST activities out of their offices for a year. In 1994 ST was officially registered as a Society. The First Annual General Meeting was held in March 1995, at which the first Executive Committee was elected and membership fees decided upon.
 
Today Somarelang Tikologo has more than 500 individual members, 50 corporate members and 22 Life members supporting its network in Botswana. An Environmental Resource Centre operates daily at the office, and publications include fact sheets, newsletter, workshop proceedings and educational materials.
