In developing countries, noise exposure and its negative health effects have been little explored. The present study aimed to assess the noise exposure situation in adults living in informal settings in the Western Cape Province, South Africa. We conducted continuous one-week outdoor noise measurements at 134 homes in four different areas. These data were used to develop a land use regression (LUR) model to predict A-weighted day-evening-night equivalent sound level (Lden) from geographic information system (GIS) variables. Mean noise exposure during day (6:00-18:00) was 60.0 A-weighted decibels (dB(A)) (interquartile range 56.9-62.9 dB(A)), during night (22:00-6:00) 52.9 dB(A) (49.3-55.8 dB(A)) and average Lden was 63.0 dB(A) (60.1-66.5 dB(A)). Main predictors of the LUR model were related to road traffic and household density. Model performance was low (adjusted R2=0.130) suggesting that other influences than represented in the geographic predictors are relevant for noise exposure. This is one of the few studies on the noise exposure situation in low- and middle-income countries. It demonstrates that noise exposure levels are high in these settings.

Due to a lack of adequate water and sanitation infrastructure, growing, unplanned urban settlements in South Africa and elsewhere have been linked to pollution of critical river systems. The same dynamics undermine local resilience, understood as the capacity to adapt and develop in response to changes, persistent social and ecological risks, and disasters. Water and sanitation challenges undermine resilience by causing and compounding risks to individuals, and to household and community health and livelihoods, in a complex context in which communities and local governments have limited capacity and resources to respond appropriately. Household and community resilience in informal settlements is drawing increasing policy focus, given the persistence of these kinds of neighbourhoods in cities and towns in Sub-Saharan Africa and South Africa, in particular. This case considers whether bottom-up responses that combine public and private sector resources, including community participation, and use an interdisciplinary approach can support the production of novel resilience-fostering solutions. This article presents an analysis of the case of Genius of Space waste and wastewater management infrastructure in the Western Cape, South Africa. While the process has been imperfect and slow to show results, this analysis reflects on the gains, lessons and potential for replication that this work has produced. The Genius of Space approach adds to a growing area of practice-based experimentation focussed on incrementalism and adaptive development practices in urban environments, particularly in developing countries.
