AUTHOR=Howland Olivia TITLE=A tale of two rivers: development, destruction, and despair in Ongata Rongai, Kenya JOURNAL=Frontiers in Public Health VOLUME=Volume 11 - 2023 YEAR=2023 URL=https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2023.1164881 DOI=10.3389/fpubh.2023.1164881 ISSN=2296-2565 ABSTRACT=Ongata Rongai is a rapidly growing peri-urban space in Nairobi Metropolitan, Kenya. The last ten years have seen exponential population growth and building development leading to overcrowding and pressure on water and environmental resources. This original research sheds light on interactions between humans, animals and this rapidly changing urban environment. It is therefore a quintessentially One Health study.Qualitative and ethnographically informed methods are employed to better understand the impact of rapid growth on the riparian environment, and the effect of this on those who depend on it. The reflexive use of archival material and an historical ethnographic approach enabled in-depth narratives to address these issues within a longitudinal context, and the use of deliberate walking alongside visual methodologies and more traditional anthropological methods make this study novel both in terms of methodological approach and findings.The study finds that people cite high levels of pollution from solid waste and sewage have made the rivers almost unusable, and a hazardous place for both humans and animals. Yet in the past, these rivers played key roles in daily life. There is a frustration with structural level actors' moribund attitude to the environment. The poor health of the rivers and riparian environment leads to human and animal health challenges, increased pressure on water resources, and economic pressure due to a loss of livelihoods.The study contributes to what is currently a fairly small literature on urban riparian spaces globally, but one which is of growing and of vital importance given the rapidly increasing percentage of humans who now reside in urban spaces. It contributes to WASH and urban clean water knowledge as well as One Health, public health, and urban growth narratives, and directly addresses challenges faced by SDG 6.
