- Description: Ways of conceptualising the world around us and being in this world are defined by an ontological understanding. Within a Eurocentric ideological understanding, nature is positioned to be opposite to culture, ie, nature is considered as “other” of which humans are not a part. Modernity is perceived as the antithesis of nature as processes of production, metabolism and expansion of modern cities represent attempts to tame and control nature. In turn, cities have become viewed as agents of development and change, promoting ideals of progress, thinking and innovation (Jayne 2005). Eurocentric ideals are framed as the forerunners of these processes and have come to influence international policies, global governance, alliances and networks which have in turn informed the design and governance of cities and influenced all aspects of urban liveability (Bouteligier 2011), including how urban natures are defined and constructed and the wellbeing benefits derived from them.

- Description: The contribution of ecosystem services to smallholder agriculture is widely recognised. However, they are seldom analysed in tandem with the ecosystem disservices, such as crop weeds and pests, which the same systems produce. We do so by quantifying the provisioning ecosystem services and disservices in smallholder arable agricultural systems in three rural villages in southeastern South Africa. Using a mixed methods approach we consider the relative benefits from ecosystem services after the effects of disservices, and the management and strategies that households adopt to minimise disservices. The role of ecosystem services and disservices was expressed in economic terms to provide a common framework to assess the relative magnitude of their contribution or loss.

- Description: Globally, approximately one billion people benefit from contributions of wild foods to their food security and dietary diversity. Wild foods are known to be important in rural communities in terms of food and micronutrient provision, diversifying diets, reducing vulnerability to non-communicable diseases and overall health. However, the potential contribution of wild foods towards food security and dietary diversity in urban food systems has been largely overlooked. This study examined the contribution of wild foods to household dietary diversity in two towns in South Africa, based on a survey of 137 households.

- Description: Wild edible fruits (WEFs) are important non-timber forest products (NTFP) that are commonly grouped with other wild foods or NTFPs in general. We hypothesize that WEFs, other wild foods, and non-food NTFPs contribute in different ways to household economies. Using data collected through a survey of 503 households in South Africa, we describe patterns of use of WEFs across socioeconomic and geographical gradients and compare them to the patterns of use of other wild foods and non-food NTFPs. WEFs were used by one-fifth of all sampled households, independent of economic and urbanisation gradients and were grown in or collected mostly from surrounding areas. More households, usually in rural areas, used other wild foods and non-food NTFPs, which were often purchased from other collectors.

- Description: Urban green infrastructure provides ecosystem services that are essential to human wellbeing. A dearth of national-scale assessments in the Global South has precluded the ability to explore how political regimes, such as the forced racial segregation in South Africa during and after Apartheid, have influenced the extent of and access to green infrastructure over time. We investigate whether there are disparities in green infrastructure distributions across race and income geographies in urban South Africa. Using open-source satellite imagery and geographic information, along with national census statistics, we find that public and private green infrastructure is more abundant, accessible, greener and more treed in high-income relative to low-income areas, and in areas where previously advantaged racial groups (i.e. White citizens) reside.

- Description: This study presents an integrated examination of both the ecosystem services (ES) and ecosystem disservices (EDS) associated with smallholder animal husbandry in rural livelihoods in three villages in southeast South Africa. It recognises the contribution of ES supporting and resulting from smallholder livestock and poultry production, but also details the limiting factors or EDS, such as tick-borne disease, birds of prey or unpalatable rangeland, produced by the same system. Using a mixed-methods approach, including focus group discussions with various Participatory Learning and Action (PLA) activities, key informant interviews, household surveys and land-use change mapping on GIS, we consider the relative value and benefits from ES after the effects of EDS, as well as the management and strategies that households adopt to minimise EDS.

- Description: South Africa has potential to export honey products through promoting beekeeping as an income generating opportunity amongst rural communities. Formalised beekeeping may also reduce wild fires initiated by hunters of wild bee hives. This study examined the contribution of the African Honey Bee (AHB) initiative to rural livelihoods and the incidence of forest fires using a mixed methods approach. The initiative increased incomes of newly trained and active beekeepers, although success rates and honey yields were variable. Core challenges included not catching bees, theft and vandalism of hives, insufficient bee forage, drought and pests. Most respondents also perceived an increase in crop size since AHB began, although few attributed this to pollination from the bees. The number of wild fires attributed to honey hunters more than halved after AHB began. Future steps need to reduce the challenges and integrate beekeeping into broader agriculture and forest conservation programmes.

- Description: Urban green infrastructure (UGI) provides numerous environmental, social and economic benefits through direct and indirect use of ecosystem services. The maintenance of UGI also provides work opportunities for skilled and unskilled workers in the public and private sectors, so-called green collar jobs. However, the extent and benefit of such employment has rarely been examined, especially in a developing country context where unemployment is often high. We quantified the number of green collar jobs and wage levels across all green collar categories in 12 towns of the Eastern Cape via means of questionnaires and interviews. Overall, we enumerated 17 429 jobs, receiving approximately ZAR503 million (US$37 million) per year. The number of jobs was strongly linked to town size, but the number of jobs per unit area was inversely related to the level of underdevelopment or deprivation per town.

- Description: Understanding of urban residents’ preferences and dislikes for tree species and attributes is necessary to provide them with the species they most favour. Yet there is relatively little understanding of local species preferences, the reasons underlying them and how they vary with context and scale. We interviewed 1100 urban residents in eleven towns (four in Zimbabwe, four in Limpopo Province and three in the Eastern Cape of South Africa) to determine what were their favourite and least favourite tree species and the reasons for such. Fifty-nine species were listed amongst the preferred species (the four most common being Jacaranda mimosifolia (10% or respondents), Mangifera indica (10%), Adonsonia digitata (7%) and Colophospermum mopane (7%)), and 29 as disliked (the four most common being Vachellia spp, J. mimosifolia, Euphorbia spp. and Melia azedarach), with 16 in common between the two.

- Description: The production of plant fibre products is considered a promising pathway for contributing to people’s livelihoods particularly in developing countries, where economic options might be limited. However, there are limited comparative studies across countries on plant fibre products, making it difficult to examine how local and broader biophysical, socioeconomic, cultural and policy contexts influence craft production patterns in terms of primary plant resources used, products made and contributions to livelihoods. Using household surveys for data collection, this paper presents findings from a comparative analysis of plant fibre craft production and income in three southern African countries, Eswatini, Malawi and Zimbabwe.

Accordingly, a diversity of uses, experiences, cosmologies, interactions and engagement with the nature are now found which, for many, offer opportunities to strengthen a sense of wellbeing and belonging. Within these diversities of ontological framings of nature and ways of being, conflicting tensions emerge which are further impacted upon by micro and macro social, economic and political processes.

- Description: Urban greenery provide a variety of goods and services to city dwellers. A core one is amelioration of the urban heat island effect. However, the many estimates from temperate regions cannot be extrapolated to the tropics, where more empirical studies are required to guide urban planning and optimization of green infrastructure design and distribution. This study reports on the temperature differentials in fortnightly readings, in winter and summer, between 12 urban green spaces and the surrounding built-up urban matrix at increasing distances from each green space. Additionally, the value of energy costs saved for air conditioning by urban greenery was calculated.

- Description: The pepper-bark tree (Warburgia salutaris) is one of the most highly valued medicinal plant species worldwide. Native to southern Africa, this species has been extensively harvested for the bark, which is widely used in traditional health practices. Illegal harvesting coupled with habitat degradation has contributed to fragmentation of populations and a severe decline in its distribution. Even though the species is included in the IUCN Red List as Endangered, genetic data that would help conservation efforts and future re-introductions are absent. We therefore developed new molecular markers to understand patterns of genetic diversity, structure, and gene flow of W. salutaris in one of its most important areas of occurrence (Mozambique).

- Description: Colonialism is a significant legacy across most aspects of urban form, the nature and distribution of public green spaces, and tree species composition in many cities of the Global South. However, the legacy effects of colonialism on urban green infrastructure and the uses thereof have only recently come under scrutiny. Here we collate information from South Africa on urban greening and interpret it through a colonial and apartheid legacy lens in relation to the distribution and types of urban nature found and their resonance with contemporary needs as an African country.

- Description: This chapter examines current knowledge relating to the human and social dimensions of biological invasions in South Africa. We do so by advancing 12 propositions and examining the evidence for or against each using South African literature. The propositions cover four broad issues: how people cause invasions; how they conceptualise them; effects of invasive species on people; and peoples’ responses to them.

We do so by advancing 12 propositions and examining the evidence for or against each using South African literature. The propositions cover four broad issues: how people cause invasions; how they conceptualise them; effects of invasive species on people; and peoples’ responses to them. The propositions we assess include:(1) intentional introductions were and continue to refiect the social ethos of the time;(2) people go to great lengths to ensure that newly introduced species establish themselves;(3) human-mediated modifications help invasive species to establish;(4) how people think about and study invasive species is strongly shaped by social-ecological contexts;(5) knowledge and awareness of invasive species is low amongst the general public;(6) personal values are the primary factor affecting perceptions of invasive alien species and their control;(7) specific social-ecological contexts mediate how invasive species affect people;(8) research on social effects of invasive species primarily focuses on negative impacts;(9) the negative social impacts of invasive species on local livelihoods are of more concern to people than impacts on biodiversity;(10) people are less willing to manage species regarded as ‘charismatic’;(11) social heterogeneity increases confiicts around the management of biological invasions; and (12) engagement with society is key to successful management. By advancing and questioning propositions, we were able to determine what is known, provide evidence for where gaps lie, and thus identify areas for future research.

- Description: Provisioning ecosystem services of the Likangala River Catchment in southern Malawi are important for livelihoods of those living there. Remote sensing, participatory mapping and focus group discussions were used to explore the spatio-temporal changes and trade-ofs in land-cover change from 1984 to 2013, and how that afects provisioning ecosystem services in the area. Communities derive a number of provisioning ecosystem services from the catchment. Forty-eight species of edible wild animals (including birds), 28 species of edible wild plants and fungi, 22 species of medicinal plants, construction materials, ornamental fowers, frewood, honey, gum, reeds and thatch/weaving grasses were derived from the catchment and used by local communities.

- Description: Urban ecosystems provide goods and services critical to livelihood sustenance, environmental protection and sustainability. However, the potential role of some urban ecosystem services such as the provisioning services, to promote liveable cities and livelihood resilience is seldom considered. This study reports on the prevalence and pattern of wild plant foraging and uses in the towns of Potchefstroom and Thabazimbi, South Africa, based on a random sample of 374 households. Descriptive and inferential statistics were used for analysing data. Foraging wild plants was integral to livelihoods and traditions and provided household energy, dietary diversity, health, and cultural affirmation, among others. About 68 % of the respondents reported foraging wild plants, albeit at varying degrees between and within towns.

Urban foraging: land management policy, perspectives, and potential

- Description: Gathering of uncultivated food from green spaces, also known as foraging, is observed in urban areas across the world, but the literature focuses predominantly on the global north. Our study examines the existing urban land management structure and its approach to urban foraging in the eastern coastal region of South Africa. Through interviews with municipal officials in nine cities, we identified different stakeholders and their roles in urban green space management. We then used network analysis to represent interactions and influence of these stakeholders, and environmental worldviews to determine organisational and perceptual barriers to and enablers of foraging in urban green spaces. The policy on urban green space management, as well as land managers themselves are amenable to the concept of foraging in public spaces. Lack of knowledge on wild indigenous species and sustainable offtake, ambiguous, coarse, or lacking policy, and normative views of pristine nature may hinder foraging. We recommend pathways for policy and stakeholder partnerships to incorporate sustainable foraging in their biodiversity conservation and land stewardship strategies.

- Description: There is no longer any doubt that an important component of and contributor to human wellbeing is the natural environment in which people live, work and relax (Summers et al. 2012). Whilst initial ideas of human wellbeing, early in the second half of the 20th century, focussed on objective measures that could be quantified and contribute to humans’ basic needs, they have evolved a great deal since, despite the lack of consensus on a precise definition of human wellbeing (Summers et al. 2012). Over the last five decades the conceptions of human wellbeing have become more complex and inclusive of the more subjective and less tangible components of human existence, including the natural environment (King et al. 2014).
