Noise Measurements

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.

Sediment Phosphorus

AbstractA major challenge for water resource management in Western Cape, South Africa, is the reduction of the growing sediment and nutrient loads in coastal areas, which belong to the areas most affected by land use change. We used the WebGIS based software STOFFBILANZ to simulate runoff, soil loss, sediment, phosphorus, and nitrogen input in the surface water and groundwater of study area (ca. 6,450 km²). The simulated runoff shows a large regional variability caused by the heterogeneous distribution of rainfall. For the reference catchment Klein River simulated total daily runoff fit the observed values of the reference year 2012. The calculation of potential input of sediment, phosphorus, and nitrogen into waters is based on aggregated or generalized information on climate data, land use types, crop and fruit types, yields, mineral fertilizers, farm manure, nitrogen fixing by leguminous plants, atmospheric nitrogen deposition, and soil denitrification. Critical source areas for potential sediment input, particulate P input and diffuse N input are mainly agricultural areas. Additionally, point sources of high relevance for N and P are found in urban areas. Based on the potential input of sediment and nutrients the impacts of current land use change on water resources were estimated. We used the web-based information system WebLand for the simulation aiming at the provision of stakeholders with information for decision making in water resource management.

The Impact

Thirteen onshore wind farm projects, totalling approximately 700 wind turbines, are proposed for the West Coast Region (WCR) of the Western Cape Province in South Africa. Wind energy exploitation possesses the ability to transform what can be classified as natural landscapes into landscapes of power, making the type of landscape on which wind turbines are deployed a prominent factor in its social acceptance or rejection. This paper examines the landscape aesthetics and land use interference of proposed wind farms in the WCR of South Africa through determining if social acceptance or rejection of proposed wind farms is dependent on the residents and visitors scenic and land use valuation of the natural landscape. The results indicate that the visual intrusion of wind turbines is the impact that respondents are least concerned with contrasting with the findings of international literature and further reasons for this anomaly are interrogated against the background of South Africa’s dire electricity needs. The paper concludes that visual impact assessments alone are not sufficient for evaluating landscapes and this paper recommends that participatory geographic information systems (PGIS) be used in addition to existing wind energy landscape assessments.

Spatial Environment

Our spatial environment is one of the most important determinants of our well-being and life chances. It relates to schools, opportunities, businesses, recreation and access to public services. Spatial injustice results where discrimination determines that spatial environment. Since Apartheid in South Africa epitomised the notion of spatial injustice, tools and instruments are required to transform spatial injustice into spatial justice. One of these is the employment of principles of spatial justice. While the National Development Plan (NDP) recognised that all spatial development should conform to certain normative principles and should explicitly indicate how the requirements of these should be met, the Spatial Planning and Land Use Management Act 16 of 2013 (SPLUMA) contains a more concrete principle of spatial justice. It echoes aspects of both the South African land reform programme and global principles of spatial justice. Essentially section 7(a) of SPLUMA entails three components: (1) redressing past spatial imbalances and exclusions; (2) including people and areas previously excluded and (3) upgrading informal areas and settlements. SPLUMA directs municipalities to apply the principle in its spatial development frameworks, land use schemes and, most importantly, in decision-making on development applications. The aim of this article is to determine whether the application of this principle in practice can move beyond the confines of spatial planning and land use management to address the housing issue in South Africa. Central to housing is section 26 of the Constitution, that has received the extensive attention of the Constitutional Court. The court has not hesitated to criticize the continuing existence of spatial injustice, thus contributing to the transformation of spatial injustice to spatial justice. Since planning, housing and land reform are all intertwined not only the role of SPLUMA, but also the NDP and the myriad other policies, programmes and legislation that are attempting to address the situation are examined and tested against the components of the principle of spatial justice in SPLUMA.
