Frances Gamble

Career

In January 1972, Niven was appointed as a climatologist at the University of Witwatersrand in the Department of Geography and Environmental Science. Niven conducted fieldwork and regularly scheduled trips to Pilgrim's Rest for her students to gain firsthand experience in research. She married W. A. L. Gamble and together they had a daughter Caryn. In 1982, she earned her PhD, from the University of Natal with a thesis called The Management of Karst Cave Ecosystems in the Transvaal. It was the first work in South Africa, and according to professor Margaret E. Marker, the only work up to Gamble's death which evaluated cave climatology and advocated for cave conservation.

Gamble's various works, which included more than twenty publications on caves, examined not only natural phenomena like radiation levels, but also the impact of human development and tourists upon cave systems. In her extensive work on cave conservation, she recommended that scientists be involved in the management and creation of guidelines for the preservation and use of cave ecosystems. Among the issues she noted were that tourists and city planners often caused environmental deterioration. Among the problems caused by urbanization, she noted pollution, including sewage, agricultural contamination, and smoke; changes in ventilation and airflow; hydrology changes caused by the development of agriculture, buildings, roads, parking lots, and pumping stations; and damage due to blasting. Issues introduced and caused by visitors included litter and graffiti, lighting systems and lampenflora, interchange of flora and fauna, and removal of materials like guano and geological formations.

Gamble began lecturing part-time in 1985 first in the Department of Town and Regional Planning and then in the School of Mechanical Engineering. She remained linked with the University of Witwatersrand until 1995. Her work on environmental education for youth included publications, competitions, and clean-up efforts at various sites, emphasizing the need to protect caves. She served as the president of Environmental Education Association of South Africa (EEASA) between 1986 and 1989 and was an officer of the organization until 1992. She was particularly noted during her tenure at EEASA for attracting sponsors to keep their journal afloat and establishing administrative procedures which allowed South African scholars access to cross-border collaborations. Gamble was a founding member of the Cave Research Organisation of South Africa, an association focused on increasing professionalism and scientific research in speleology in the country. She was also a member of the British Cave Research Association and the United States-based National Speleological Society. She served as the South African delegate to the International Union of Speleology, and was president of the South African Geographical Society between 1989 and 1991.

Death and legacy

Gamble died of colon cancer on 27 March 1997 at the Brenthurst Clinic in Braamfontein and was buried on 14 April in Johannesburg. Scholar Stephen A. Craven, noted in 1992, that her contributions were "the most exhaustive work on cave conservation in South Africa". During a time when Apartheid policies restricted the ability for scholars within South Africa from collaborating with international researchers, Gamble introduced interdisciplinary curricula for environmental science at the University of the Witwatersrand and built networks with international partners to facilitate education and research.
