The societal benefits of addressing wasteful electricity use practices through behavioural interventions are now well-established. Surprisingly, in South Africa, where the economy is highly dependent on fossil fuel (coal) for electricity generation, this subject remains little studied and understood. The residential sector is a major electricity consumer, and high-income households, in particular, use a substantial proportion of total electricity with serious adverse impacts on grid stability and the environment, which can disproportionately affect the poor. Using a field-based experiment, this study examines the impact of behavioural interventions on household electricity savings and the determinants of success among high-income households in Johannesburg, South Africa. Over the intervention period, households exposed to a combination of electricity-saving information, frequent reminders and feedback on monthly electricity-saving performance showed mean electricity savings of about 1.5%, ranging from 2% to 4% of electricity, while households in the control group showed increased electricity consumption by approximately 11%. Out of all the demographic and personal value factors considered, age, achievement and benevolence promoted electricity savings, while household size, number of rooms, baseline electricity consumption and security inhibited savings. The findings empirically validate the impact of behavioural interventions on, and the positive influence of, personal values in promoting participation in electricity-saving actions within households.

Highlights • The perceptions, practices and willingness to pay for continued use of plastic bags were investigated in South Africa. • The high usage of plastic bags was primarily attributed to convenience. • Age, gender, and education level influenced consumers' willingness to pay for plastic bags. • Potential interventions for reducing plastic bag use are discussed. Abstract Single-use plastic shopping bag consumption is one of the leading causes of environmental and socio-economic problems worldwide, which has led to global calls for intervention strategies to reduce use. In South Africa, plastic bag use is still widespread despite intervention efforts based on levying taxes. Using an online questionnaire, this study examines plastic bag use practices and factors influencing use in South Africa. The results show that the majority of respondents perceived there was a plastic bag use problem in the country but still highly used plastic bags because it was convenient to do so. Factors like, gender, age, education and environmental consciousness influenced people's willingness to pay for plastic bags but the relationships were generally weak. The paper outlines which interventions might be most effective in achieving pro-environmental actions. [ABSTRACT FROM AUTHOR]

Estimation of food waste generation represents the first step when considering efforts to reduce waste generation and monitor food waste reduction against set targets. This study reports on an estimation of food waste generated in university dining halls at Rhodes University, South Africa. Daily food waste generation was estimated at about 555 g per student or 2 tonnes across all sample dining halls, translating to about 450 tonnes per year. The results show that food waste is influenced by an array of contextual factors, including distance to dining hall, gender composition of hall and meal times and meal options. It is estimated that the university could save up to US$ 80 000 annually for every 10% reduction in the current rate of food waste generation. Possible educational, technical and administrative interventions for food waste reduction are discussed. [ABSTRACT FROM AUTHOR]

The rapid expansion of student numbers, staff and support infrastructures in higher education institutions often result in increased demand for resources such as energy and paper. Promoting pro-environmental behaviour is critical if higher education institutions are to achieve sustainable resource use. Using surveys, reported energy use and recycling behaviour of staff and students in the Faculty of Education at Rhodes University, South Africa was explored. The results showed that self-reported pro-environmental behaviour was mediated by demographic factors and personal values such as ‘liking of aesthetic beauty and biodiversity’, ‘social relations’, ‘a varied life’ and ‘freedom’. Personal values, though key in shaping participants' attitudes toward the environment did not always translate into pro-environmental behaviour. Situational factors beyond the control of participants were cited as barriers to pro-environmental actions. Lessons from this study point to the need to carefully study the assumptions underlying intervention strategies aimed at promoting pro-environmental behaviour and to get rid of barriers to enable pro-environmental actions.

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. [ABSTRACT FROM AUTHOR]

In assessment of costs (and benefits) of wildlife conservation, conventional economic valuation frameworks may inadequately address various non-tangible values and neglect social, cultural and political contexts of resources and their use. Correspondingly, there seems to be much more focus on quantifying the economic, material benefits and costs of wildlife conservation than the non-material aspects that also affect human well-being. In addition, current research on the costs of wildlife conservation tends to be discipline-focused which constrains comparability, often causing conceptual ambiguity. This paper is an attempt to address this ambiguity. While there is growing acknowledgement of the material costs of wildlife conservation, we contend that employing a broader, composite social well-being approach may provide better conceptual insights on—and practical options for—managing various non-material impacts of wildlife conservation for local people. Non-material impacts such as negative physical or psychological experiences, trauma, feelings of fear and anxiety cannot directly be measured by or converted to money but such impacts still lead to human ill-being. Thus, taking these impacts into account is critical for the broader sustainability of wildlife conservation, making understanding and addressing them a key socio-ecological issue. • Current research on the costs of wildlife conservation tends to focus on material aspect of human well-being. • Limited studies on non-material costs are characterised by conceptual ambiguity, which limits comparability. • A better understanding of non-material costs of wildlife conservation can improve wildlife conservation. • We define, categorizeand characterize non-material costs of wildlife conservation. • Implications for measuring non-material costs and designing socially just conservation interventions are discussed.

Worldwide, households' consumption of electricity contributes to a substantial proportion of total national energy demand. Thus, the residential sector is a major entity in efforts to define and achieve global sustainability goals. Understanding electricity use behaviour and factors underlying behaviour is critical for designing behaviour change interventions, particularly in contexts characterised by fast-growing economies, burgeoning number of high-income households, and consumption growth. However, relative to developed economies, very little is known on this subject in South Africa. Using structured questionnaires, this study examines electricity use behaviour among high-income households in Johannesburg, South Africa. Findings indicate evidence of electricity-saving behaviour, but the proportion of households doing so was less than 50% for many actions, indicative of widespread wasteful habits. Other particular wasteful electricity use habits include leaving electronic gadgets and appliances on 'standby' mode, not turning off electric water heaters and not defrosting fridges without automatic settings. The findings lend support to the positive and negative influence of self-transcendence and egoistic values respectively on environmental behaviour, but other value orientations did not yield significant relationships. The implications of the findings on practical interventions for and theoretical constructs underlying strategies for environmentally-sustainable behaviour are discussed. [ABSTRACT FROM AUTHOR]
