Jackie King is an aquatic ecologist and an Extraordinary Professor in the Institute for Water Studies since 2012. She previously worked as a researcher, lecturer and supervisor of postgraduates at the University of Cape Town for almost four decades. She now owns and runs Water Matters, a water-resource consultancy specialising in the science of integrated flow management (instream flows; environmental flows) of rivers and is an internationally recognised leader in the field.

Prof King is the 2019 Stockholm Water Prize Laureate for her game-changing contributions to global river management.

In 2018 Prof King was elected an International Member of the American Academy of Arts and Sciences (AAAS). https://members.amacad.org/content/members/newfellows.aspx?s=a

In 2016 she received the Gold Medal of the Southern African Society of Aquatic Scientists and was the 2016 recipient of WWF-SA’s Living Planet Award.

Her work in South Africa was recognised in the 1990s with a Silver Medal from the Southern African Society of Aquatic Scientists and in 2003 through the government awarding her the national Women in Water Award in the research category. In 2010 she was appointed an inaugural member of the National Water Advisory Council to advise the South African Minister of Water Affairs.

In 2010 Prof King was first editor and an author of the book Sustainable use of South Africa’s inland waters, which records South Africa’s moves to provide environmental protection measures for aquatic ecosystems. In 2014 she was the lead author of the chapter Hydropower and the river in a book Sustainable hydropower in Asia planned by the Asian Development Bank. In 2016 she wrote, as part of a team of four, a Good Practice Handbook for World Bank project managers worldwide dealing with downstream releases linked to proposals for hydropower dams. She also provided the ecological input to a World-Bank funded Multi-sectoral Investment Opportunities Assessment of the Okavango River Basin and provided similar inputs to a DFID-funded project on Climate Resilience Development Pathways for the Okavango Basin. She is presently the Ecological Lead in an EU-funded project Technical Assistance for Transboundary Water Management of the Okavango River Basin.

Prof King believes that the social and ecological consequences of the development of river systems should be addressed at the same level as engineering and economic aspects, so that decision-makers can assess the full spectrum of costs and benefits before making a development decision. In the 1990s she led the early development of methods to do this in South Africa, which resulted in flows for river maintenance being included in the country’s 1998 National Water Act: South Africa’s Minister of Water Affairs and this Act won the Stockholm Water Prize in 2000.

 In 1997, Prof King led the flow assessment for the Lesotho Highlands Water Project, which resulted in the first recorded recognition globally of the rights of downstream communities to compensation for declining river health. She was global Team Leader of the World Bank advisory group on environmental flows from 2000-2003 and resigned from that position to take up one as a scientific consultant on integrated flow management to the Mekong River Commission.

Since 1997 she has also led scientific teams working on environmental flows and river system management for the Pungwe River, Zimbabwe; parts of the Zambezi Basin (Kafue and Luangwa); the Pangani Basin, Tanzania; the Okavango River system (Angola, Namibia, Botswana); and the headwaters of the Indus River system in Pakistan. She has been contracted to do work of a similar nature for the World Commission on Dams, World Bank, IUCN, WWF, and has worked in Taiwan, Ethiopia, Costa Rica, USA, Guatemala, Australia, Mozambique, and the UK.

From 2009 to 2014 she acted as scientific advisor to the Government of Pakistan in a dispute with India over the Kishenganga Dam in the Himalayas, and in this respect served as an expert witness at the Permanent Court of Arbitration in The Hague in August 2012. In 2012 she completed for WWF a plan for setting and implementing Environmental Flows for the entire Zambezi Basin, and between 2013 and 2018 worked with WWF-Zambia and the Zambian government on flow management of two parts of this system: the Kafue and Luangwa tributaries of the Zambezi.

Prof King frequently speaks as a keynote or invited speaker at international conferences, and has more than 100 refereed items in books, international journals and conference proceedings.

She presently serves on the Board of Directors of WWF-SA and the Research Advisory Panel of South Africa’s Council for Scientific and Industrial Research. She serves as a Senior Scientific Advisor to the International Crane Foundation and as a member of AAAS’s global project Water Security in a Changing Climate. She is a South African National Parks Honorary Ranger, serving on the Regional Committee for the Table Mountain National Park region and holding the Training portfolio.

Biography:

I study the morphodynamics of fluvial ecosystems (rivers and wetlands) in warm humid, sub-humid and semi-arid environments, over timescales ranging from decades to millennia. Through my research I have applied and integrated analyses of hydrology, geomorphology, and ecology to understand physical and biophysical drivers of fluvial ecosystem origin and dynamics. Through both research and vocational practice, I have considered the role, value and challenges of applying such understanding to the management and restoration of wetlands in particular, where geomorphological insight into processes and rates of morphological change is a critical but often neglected component of restoration planning. I favour research approaches that combine insights from a variety of techniques that make independent simplifying assumptions about the nature and dynamics of ecosystems, such as spatial analysis and remote sensing, fieldwork and geochronology, and numerical morphodynamic modelling, and I endeavour always to develop and teach system-level understanding that I believe has great value in management, restoration, and the evaluation of ecosystem services. During my academic career, I have walked in and/or worked on rivers and wetlands across South Africa, Australia, New Zealand, Papua New Guinea, the UK, the Swiss Alps, Austria, and Italy. This global ‘field experience’ has significantly shaped my view of nature, my understanding of the Earth system, and my approach to research and teaching. I teach introductory soil science, surface water processes, fluvial geomorphology, and aquatic ecosystems management.
