Illegal solid-waste dumping (ISWD) is prevalent globally with adverse social and environmental impacts, particularly in poor communities. Understanding the extent, practices and perceptions of ISWD is needed to inform interventions. Using GIS techniques and household surveys, this study examined the prevalence of dumpsites, and perceptions of ISWD in a low-income neighbourhood of Komani, South Africa. A total of 120 dumpsites were encountered in green spaces, empty residential plots and street edges, suggesting illegal dumping of solid waste is widespread. More than half of the respondents (58%) disposed of household waste in undesignated sites or burnt it, attributing this to the non-collection of waste. Potential interventions suggested were largely technical, including regular collection of waste, and the provision of bins and plastic bags. The paper suggests approaches to addressing sustainable solid-waste management should consider the views of local communities, who are principal stakeholders in the solid-waste production and management mix.

With inequality persistent across geopolitical contexts, 'transformation' continues to be expediently cited in the rhetoric of higher education institutions. Illuminating alike issues worldwide, the paper critically examines race, inequality and oppression among the black and women academics who were selected as recipients of post-apartheid academic development programmes at an historically white institution in South Africa. Utilising a report-and-respond approach, participants initially responded in a questionnaire to definitions of notions of transformation espoused within The Integrated Transformation Plans of South African universities. This was followed by non-deterministic small group discussions of the researchers' interpretations of those responses. The recipients' lived experiences provide deep insights, from within, into the misalignment between those discourses espoused and those practiced, which have implications for transforming the institutional culture of the dominant in-group. Emerging ahead of the implementation of a self-regulatory tool for higher education institutions across that national context, many of the participants called for structural accountability mechanisms in the face of their frustration with current ineffectual approaches. A concern about institutional responsiveness to research findings of such critical studies is raised. (HRK / Abstract übernommen).

Human behaviour is at the centre of most environmental problems; hence, the promotion of pro-environmental behaviour is considered to be a pathway towards sustainability. Despite the availability of insights gained from pro-environmental behaviour studies, mainly from household and workplace settings, a key question remains—can these insights be applied in university residence settings? Within university campuses, student residences are a major entity in sustainability debates because they are major consumers of resources including paper, water and energy with severe repercussions for university budgets and the environment. Using a questionnaire survey, this study explores reported pro-environmental behaviour and its determinants at Rhodes University, South Africa. Data were analysed using descriptive and inferential statistics where relevant. The findings show a high level of heterogeneity in reported pro-environmental behaviour, attributed to a suite of internal and external factors. Internal dispositional factors seemed to constrain students from acting pro-environmentally. This study highlights the need to encourage environmental behaviour in university residence settings by supporting the antecedents of and getting rid of barriers to pro-environmental actions.

Drought is a natural phenomenon which can cause widespread socio-economic and environmental impacts. Recent predictions suggest that drought frequency and intensity will increase in Southern Africa; therefore, there is a need for more scientific information on drought impacts and responses by vulnerable groups such as smallholder farmers. This scoping review examines the current state of research and conceptual insights on the impacts of drought on and responses by smallholder farmers in rural and urban settings in South Africa. We used three bibliographic databases (Scopus, Web of Science, and EBSCOHost) to search for peer-reviewed literature published on South Africa. In total, 18 articles were reviewed, and information on drought impacts and responses among smallholder farmers was analysed and synthesised. Although most of the reviewed papers identified several socio-economic (e.g., loss of livestock, income, and employment) and environmental (e.g., loss of grazing land and vegetation) impacts of drought, the identified impacts were rarely quantified, and there is a lack of analytical depth of these impacts. Smallholder farmers in South Africa implement several drought responses, and these were categorised based on (i) changes in local practices and lifestyles e.g., practising conservation agriculture, (ii) structural measures e.g., government relief programmes, and (iii) technical interventions e.g., rain harvesting. None of the reviewed papers reported on the impacts of and responses to drought on smallholder farmers in urban settings. Overall, the review noted that the literature on drought in South Africa lacks detailed quantification and analysis of drought impacts and responses, the urban drought context is poorly understood, and there is a lack of clarity on the distinction between adaptation and mitigation strategies. Improving our understanding of drought impacts across a rural-urban gradient is important if responses are to effectively reduce smallholder farmer drought vulnerability.

Human perceptions and knowledge of invasive alien plant species are increasingly recognised as important in the management of biological invasions, but there is limited research focus on the social dimensions of plant invasion. Using household surveys, this study assessed the perceptions, knowledge, and uses of Psidium guajava Linn. to rural communities in Vhembe Biosphere Reserve, in the Limpopo Province of South Africa. Results showed that most respondents are aware of P. guajava and perceive it to be spreading in their locality but do not consider it an invasive alien plant species. Psidium guajava is perceived to have a dual purpose and most respondents are aware of its benefits including fruit consumption, medicinal purposes, shading and firewood provisioning and costs such as attraction of problematic animals, displacement of native plants, and reduction of grazing and agricultural space. The benefits associated with use of P. guajava are considered greater than the costs, therefore most participants do not implement any control measures. These results highlight the need to incorporate rural community perceptions, knowledge, and uses of P. guajava in developing effective management plans that avoid conflicts between stakeholders. To improve the efficacy of managing biological invasions more research is required to understand how communities relate to invasive alien plant species.

Households consume up to 20% of overall electricity consumption globally; hence, they are important role players in efforts towards promoting sustainable consumption. Research on electricity use behaviour is important for informing intervention strategies; however, relative to developed countries, research on this subject is lacking in developing countries where electricity access is limited. In South Africa, electricity use behaviour among poor neighbourhoods remains little studied and understood. This study was carried out among low-income households in Makhanda, South Africa, characterised by high poverty and unemployment rates, low education levels, and limited access to basic services. Using a self-reporting approach, electricity use behaviour of low-income households was assessed against a list of common household electricity use actions. A survey of 297 households was conducted. The findings show mixed results, with households reporting both good electricity use behaviour (e.g., cooling down hot food before refrigeration and using washing machines on full load) and wasteful actions (e.g., leaving appliances on standby). Our results show that electricity use behaviour was influenced by socio-psychological values including universalism, benevolence, hedonism, and power. Some of the reported electricity behavioural patterns are consistent with those previously reported among high-income households. The theoretical and practical implications of these results are discussed.

In the context of unsustainable food choices and consumption patterns, transition to plant-based diets is considered a pathway to reducing greenhouse gas emissions. The youths, and university students in particular, represent a distinctive demographic group with great potential to follow plant-based diets, but limited knowledge concerning the prevalence and motivations of plant-based diets exists in the Global South. The aim of this study this research was to examine the prevalence of, motivations for and barriers to plant-based diets among Rhodes University students in South Africa. A total of 300 students responded positively to an online questionnaire survey. About 31% of the survey students followed a plant-based diet but this figure dropped to 18% when flexitarians were excluded from the analysis, with more females than males reporting so. The leading motivation for following plant-based diets was animal welfare concerns, followed by environmental sustainability, personal health, influence of family and friends, taste preference, saving money and sensory issues. There was a significant positive association between values relating to the environment - respecting the earth and protecting the environment and following a plant-based diet. Key barriers to plant-based diets reported included perceived high costs and lack of knowledge on plant-based diets. Interventions for promoting plant-based diets should make explicit, links between plant-based diets and the values people consider important and focus on removing constraints to encourage uptake of plant-based diets.

Human practices are at the centre of unsustainable electricity use at the household level, which means behaviour change strategies can form pathways towards electricity conservation. Although behaviour change interventions are useful in promoting electricity savings at the household level, they are rarely inclusive and informed by the users of electricity. Using a field-based experiment, this study examines the impact of co-designed interventions on household electricity consumption among low-income households in Makhanda, South Africa. The results show that co-designed interventions yielded significantly more electricity savings (5%) than prescriptive interventions (2%) over the intervention period. Participant households exposed to the co-designed interventions showed electricity savings of up to 14% post the intervention period, suggestive of positive persistent effects. Household size and employment status had a significant negative effect on electricity consumption while age, employment status, and baseline electricity consumption yielded positive effects. Electricity savings were positively correlated with involvement and trust, perceived behavioural control, and the intention to act pro-environmentally. The results highlight that co-designed interventions can yield significant electricity savings, which can in turn, result in grid stability, and reduced electricity expenditures and carbon emissions. A key contribution of this study lies in advancing our understanding of the effects of user-driven approaches in yielding persistent electricity-saving behaviour, which to date has not been a focus of intervention studies. In particular, the findings lend support to notions of supporting the agency of electricity users in co-developing solutions for local sustainability challenges.

Unsustainable use of electricity has severe implications on the environment and human well-being. With an estimated consumption of about 20% of total global electricity demand, the household sector is a key player in efforts for crafting interventions for reducing electricity consumption. Despite increasing calls for behavioural solutions to electricity conservation at the household level, more attention has been paid to technical than behavioural interventions. Yet a deeper understanding of electricity use behaviour is needed to design interventions and engender integration of behavioural interventions into demand-side management and decision making. Although South Africa is energy insecure and a major greenhouse gas emitter, less attention has been paid to household electricity use using behavioural lenses. Using a scoping review approach, this study inductively reviewed publications to examine the state of research on household electricity use in South Africa, focussing on (1) research trends and contexts, (2) conceptual focus, (3) proposed interventions for reducing electricity consumption and (4) future research needs. Very few publications considered reported and actual electricity use behaviour. Most publications (65%) paid attention to technical dimensions for reducing household electricity consumption such as economic nudges and technical retrofits, rather than behavioural strategies. Of the publications that focussed on behaviour, very few explicitly examined reported electricity use behaviour. Most publications did not consider the role of partnerships in designing interventions for reducing electricity consumption but rather employed individualistic perspectives. Overall, the results suggest that calls for behaviour change research have not been fully heeded. More studies on electricity use behaviour in different contexts, including across an income heterogeneity gradient, and the role of context dependent collective settings in drafting interventions, are required to better inform pathways to sustainable electricity use.

Solar photovoltaic (PV) systems can provide a clean and sustainable alternative to fossil fuel energy, but the uptake of solar PV systems is often constrained by perceived and actual barriers. Despite South Africa’s very high solar generation potential, solar PV adoption remains low, accounting for less than 10% of the country’s energy mix. Central to renewable energy debates is making sure that the transition is equitable, affordable, and inclusive. Yet, despite high levels of inequality, there is no empirical standing on the factors hindering solar PV adoption among a socially differentiated household gradient. Using household interviews, the study investigated barriers to solar PV adoption across an income gradient in four towns located in the Eastern Cape province of South Africa. Results showed that significantly more high-income (82%) than low-income (63%) households had considered solar PV adoption, primarily to mitigate power cuts (89%). Both income groups were constrained by financial, institutional, and social barriers, but low-income households were disproportionately affected. While 86% of high-income households cited initial financial constraints, low-income households were nearly twice as likely to worry about high maintenance costs (48% vs. 26%) and system unfamiliarity (36% vs. 14%). High-income respondents were more concerned with institutional and technical barriers, such as a lack of supportive policies and grid-feed difficulties. Nearly all (98%) low-income households lacked knowledge regarding solar PV system capacity, compared to 60% for high-income households. Altogether, the results highlight that heterogeneity matters in our understanding of barriers to solar PV adoption and should be a key consideration in designing differentiated approaches to address barriers and ensure equity in renewable energy adoption.
