South Africa is a water-stressed country with significant water management challenges. In response, progressive and advanced water management policy and legislation have been developed that include the regulation of water uses through a water use license application (WULA) system. In recent years, the effective functioning of the WULA system has co...
Article
Protected area systems are designed in law and policy towards achieving certain policy objectives. These systems rely on legal frameworks that determine how countries designate, declare and manage their protected areas. To date, little research has been conducted on the risks faced by protected area systems. To this end, this paper aims to identify...

The mismanagement of waste in protected areas may lead to significant and irreversible environmental, economic and social impacts, such as land degradation, resource depletion, surface and groundwater pollution, loss of biodiversity and impacts on the aesthetic value of these areas. This paper aims to identify the challenges and opportunities for s...
Article
In this paper we aim at determining the link between EIA report substance and administratively just EIA decisions. In so doing, previous research based on 42 case studies from South Africa, which analysed whether they comprised administratively just decisions (i.e. that were lawful, procedurally fair and reasonable) were reviewed for the substance...
Article
Privately protected areas (PPAs) are internationally considered to be important policy implementation instruments to augment and strengthen protected area networks. However, there has been limited reflection on the performance of PPAs over time. This paper aims to identify key risks to the performance of PPAs as policy implementation instruments th...
Article
Full-text available
The aim of this paper is to evaluate the environmental performance of luxury safari lodges along a performance pathway from legal compliance to best practice. The research results provide a conceptual framework and performance baseline against which lodges can then develop strategies to improve environmental performance. We achieve this aim by adap...
Article
Screening is an important step in the EIA process as it is here where the significance of possible impacts associated with a proposed development is first considered and the need for an assessment is determined. There is no one-size-fits-all approach to screening, but approaches can broadly be categorised into discretionary approaches and prescript...
Article
Full-text available
This study aimed to investigate waste separation at source behaviour among South African households in Abaqulusi Local Municipality in KwaZulu-Natal. Behaviour in this context refers to determining current waste separation practices, and the willingness of households to participate in waste separation in future. Awareness and attitudes towards sour...
Article
Environmental impact assessment (EIA) is implemented in most countries as an administrative procedure. In this context, it is subject to the principles of administrative justice. However, to date, no empirical research has been conducted to determine the extent to which EIA decisions comply with the principles of administrative justice. In this pap...
Article
Despite increased focus on environmental impact assessment (EIA) effectiveness in general, little research has been conducted on EIA effectiveness in protected areas (PAs). This paper aims to evaluate the effectiveness of EIA in PAs through the use of 42 specifically designed key performance indicators (KPIs) derived from a theory of change (ToC) a...
Article
With accelerating environmental degradation, 21st century governments are expected to govern towards more environmentally sustainable outcomes. Supreme Audit Institutions (SAIs) are increasingly recognised as having a key environmental governance role in holding governments to account by expanding their traditional financial audit mandates beyond t...
Article
Brominated flame-retardants (BFRs), including polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD), were analysed in 77 eggs of 13 wild bird species from Gauteng and northern Free State (the industrial heartland of South Africa). BFRs were in all eggs, but not all BFRs were quantifiable. Concentrations ranged between 2.9 and 46...
Article
With increased political polarisation and the emergence of populist governments around the world – many of which erode regulatory requirements such as EIA – there is an urgent need to be able to identify and explain the potential benefits of EIA for government. The aim of this paper is to explore the benefits of EIA for government as perceived by E...
Article
The costs of conducting Environmental Impact Assessment (EIA) are well known. Yet the benefits of EIA are much more intangible, leading to a situation where some question its value as the tool of choice for informing decision makers of the sustainability consequences of their actions. Exponents of EIA have thus called for more research on the benef...
Article
EIA is increasingly being questioned as a decision-making instrument of choice for decision makers. In addressing these concerns, the paper aims to re-think the fundamentals of EIA through the identification of key assumptions underlying EIA evaluation. This aim was achieved through the application of the theory of change (ToC) method to the South...
Article
The aim of this letter is to provide an administrative justice perspective on EIA effectiveness. EIA is described as essentially an administrative instrument, reflecting a number of principles that revolve around an assessment process which should reflect administrative justice. This includes lawfulness, procedural fairness and reasonableness. Cons...
Article
Full-text available
We outline the experiences and the challenges of optimizing two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC×GC-TOF-MS) in conjunction with the H4IIE-luc bio-assay for analyzing polychlorinated dibenzo-p-dioxins (PCDDs )and polychlorinated dibenzofurans (PCDFs) in the South African context. Investigating such alt...
Article
Increased urbanisation and industrialisation has been associated with increased amounts of pollutants in the environment. Persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) are common contaminants associated with human activities including combustion, industries, vehicle exhaust and domestic emissions from backyard bur...
Article
Full-text available
Polychlorinated biphenyls (PCBs) were analysed in wild bird eggs from industrialised areas in South Africa. The concentration, congener profile, feeding guild, potential associated risk and biology were investigated. PCBs were detected in all eggs with 30 congeners present in more than 80% of the samples. Σ(34)PCB concentrations ranged between 0.9...
Conference Paper
Full-text available
Despite having the largest economy in Africa, very little is known about organic pollutants in soils and sediments from urban and industrial areas of South Africa. Here, we present the results of the first studies to investigate levels and distribution of organochlorine pesticides, PCBs, PAHs, chlorinated paraffins, and dioxin-like chemicals from t...
Article
Polycyclic aromatic hydrocarbons (PAHs) are of global concern due to their ubiquitous presence, toxicity, and carcinogenicity. No data on PAHs in soils from South Africa have been published, even though it has the largest economy and industrial base in Africa. During this initial assessment, the levels of PAHs were determined in soils and sediments...
Technical Report

Sediment sampled from these sites was firstly screened for the presence of DLCs using the H4IIE-luc bio-assay. Sites eliciting quantifiable responses were selected for further chemical analysis. Of the 96 sites, only 23 had quantifiable levels of DLCs. These sites were mainly of industrial, semi-industrial or low-income residential origin. PAHs wer...
Conference Paper
Full-text available
Species specific characteristics and behavioural traits are important determinants of exposure profiles to brominated flame retardants (BFRs). Polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD) are BFRs used in industrial applications such as thermoplastics. BFRs exhibit endocrine disrupting properties and neuro-toxic effects....
