Rivers in Umlazi are one of the most polluted rivers in South Africa which results in reports of death resulting from illegal dumping. There is limited understanding of how policy and stream water quality influence people’s environmental knowledge, attitude and behavioural practice. Purpose: The aim of this study was to determine policy impact on knowledge, attitudes and behaviour toward stream restoration practices in Umlazi Township, KwaZulu Natal, South Africa Methodology: A sequential mixed method design was used in this study. Interviews and focus group discussions were used to collect data from the municipality and community organisations under exploratory design. A survey on community members of Umlazi validates the interview and focus group findings. Results: Altering physical and natural environment as part of Social Ecological Model (SEM) and improving living conditions of the citizens can be conducted by the government to yield better public health outcomes. Beta coefficients (0.168) for policies findings suggest policy impact has biggest influence in predicting behavioural change towards stream restoration and in decision making than attitude and knowledge. Even though there was lack of proper knowledge on stream water quality testing, poor attitude towards stream restoration practice was highlighted throughout the study. Citizens’ behaviour and attitude instead highlighted social disapproval towards clean stream management and 76.3% highlighted concerns of children being more vulnerable to health and safety risks. Key Contributions Made by the Study: The study proposes a model that suggests that sustainable management of river ecosystems requires a stronger inter-disciplinary approach and reclaiming the ‘water sector’ from the margins to the centre of policymaking.512 penEnvironmental knowledgeEnvironmental policiesRiversStream conservation--South AfricaStream restoration--South AfricaConservation of natural resourcesNatural resources--ManagementThesishttps://doi.org/10.51415/10321/4270
