How do urban dwellers identify with features within urban green spaces in the Eastern Cape?
No full textPublic urban green spaces contain natural and artificial features which play crucial roles in supporting urban social-ecological systems, a fact now recognized globally. The various natural and artificial features contained in public urban green spaces are said to be key contributors to the quality of life and well-being of urban dwellers. Nevertheless, this has been largely ignored in urban design in South Africa, especially in the poorer township and Reconstruction Development Program (RDP) areas. At the individual household and community levels within the poorer communities, the provision of green spaces and trees, as well as recreation facilities, is well below world standards, and much less than what is available in the more affluent areas of South African towns. Additionally, most research on the links between nature and human well-being in urban contexts comes from developed world contexts which adopt a westernized view of the relationship. Yet, in many societies of the Global South, including South Africa, worldviews and experiences of nature in green spaces and use of other recreational features takes on different meanings to those of the Global North. To show these differences, a combination of methods was used in this study, different types of green spaces were assessed and evaluated by structured observations so as to record the features present within the spaces. A survey of 360 households was conducted by targeting green space users and households within 100 metres from a green space. Results indicated that, across all the green space types, formal green spaces had a low cover of shrubs, trees and herbs whilst having high lawn cover. Furthermore, vegetation had poor rating across all the green spaces since the vegetation was either overgrown herbs, dense thickets of shrubs and mostly alien trees that were either diseased or forked. Similar to the disparity in the composition and structure of vegetation within the green spaces, there was a wide variability in the composition of recreational features and amenities across the green spaces. The formal green spaces had the most amenities like play equipment, shelter and seating. Informal green spaces and commonages had little or no recreational features available. The attributes of these spaces therefore influenced the reasons for visiting as more than 90 % of the respondents simply used the spaces for transit. With regards to attitudes and preferences towards particular features, they were emerging sense of strong negative feelings towards natural features. Most respondents emphasized the need for green spaces that are well laid out with maintained lawns, recreational facilities and open vegetation. Thus, the current design and available features within the studied urban green spaces do not meet local needs and aspirations and thus do not contribute to better well-being and quality of life as much as they could. Specifically, the various health benefits linked with being in contact with nature in the public green spaces were not evident in this study. The South African specific context in green space use, perception and people’s preferences is thus crucial for urban planning and sustainability
Integrating local indigenous knowledge to enhance risk reduction and adaptation strategies to drought and climate variability : The plight of smallholder farmers in Chirumhanzu district, Zimbabwe
No full textThis article focuses on drought risk reduction and climate change adaptation strategies
adopted by rural households to sustain their livelihood activities. The overall objective was
to understand the local household’s responses to the changing climate especially drought.
The study was carried out in Chirumhanzu district in Zimbabwe and used a mixed methods
approach combining 217 household surveys, targeted focus group discussions, participatory
learning actions methods, key informant interviews and a document review. Household
data were analysed using Statistical Package for Social Sciences and thematic content analysis
was used for the qualitative data. We found that the majority of households showed
awareness of several risk reduction and adaptation strategies to implement during and/or
when drought was predicted, with 56% of the respondents stating stocking of grain as initial
strategy. Other strategies adopted at household level included early planting (at first rains),
conservation farming, planting small grains and dry planting. Indigenous and traditional
knowledge systems and practices, including local people’s holistic view of the community
and environment, were a major resource for adapting to climate change and drought risks.
However, these indigenous knowledge systems and practices had not been consistently used
in the existing adaptation and risk-reduction efforts. Indigenous knowledge was not
sufficiently acknowledged and integrated into formal risk reduction and adaptation
strategies, which resulted in limited success for external interventions. There is need for
integration of local and indigenous knowledge systems and external interventions to build
household livelihoods that are resilient to climate risks
Attitudes and preferences towards elements of formal and informal public green spaces in two South African towns
No full textDifferent types of public urban green spaces (PUGS) contain various natural (such as trees, pools, flowerbeds) and artificial elements (such as benches, play equipment, fountains) which contribute to the enjoyment and experience of users. However, which elements users most require, appreciate or notice has rarely been examined as the basis of their choice for specific PUGS, especially in poorer neighbourhoods and countries, where formal PUGS may be limited. The study was carried out in two towns in the Eastern Cape province of South Africa, both characterized by high poverty and unemployment levels, low literacy rates and many people living without basic infrastructure and services. To understand the meanings people, have for specific PUGS elements, formal and informal PUGS and peri-urban municipal commonages were assessed with respect to the natural and artificial elements present. A survey of 360 households was conducted across two towns by targeting PUGS users and households within 100 m from the designated PUGS. Approximately 63% of the respondents visited PUGS, with informal PUGS being the most frequented. However, they were strong negative feelings towards some natural elements because of their unkempt nature. Issues of safety, cultural restrictions and lack of recreational facilities were mentioned as some of the specific deterrents against visiting the closest PUGS among different user and age groups. Most respondents emphasized the need for PUGS that are well laid out with maintained lawns, recreational facilities and open vegetation. Thus, the current design and available features within the studied PUGS do not meet local preferences and needs and thus do not contribute to enjoyment as much as they could. Attention needs to be given to understand and incorporate the elements that invoke positive attitudes among urban residents

The evolution of social-ecological systems (SES) research : a co-authorship and co-citation network analysis
No full textSocial-ecological systems (SES) research has gained substantial momentum, as witnessed by the growth in SES publications, theories, and frameworks, and the traction these concepts have gained in development and policy arenas. However, the growth and development of the SES field has only been partially examined, which limits our ability to make sense of and support the future development of the field and its ability to inform pressing sustainability challenges. The aim of this study is to understand how SES research has grown and changed over time as a field of study using bibliometric methods, co-authorship and co-citation network analysis. Our study is informed by broader bodies of work that have sought to understand the development of scientific fields, concepts, and research agendas. We highlight key trends that have influenced the organization of the field as well as how key thematic areas of SES research have evolved over time. Our results indicate that the research on SES is (i) mainly carried out by authors located in North America and Europe, (ii) characterized by changes in the terminology employed, as identified through our search terms, (iii) linked to the emergence of major conferences and centers dedicated to SES research, as well as its growth over time, (iv) characterized by a highly interconnected structure, with almost 80% of scholars being connected to each other, and (v) characterized by a shift in citation patterns, with newcomers in the network carving out their niche and replacing the founding figures as the central focus. We discuss the implications of these findings, including the nature of SES research as an epistemic network, the highly collaborative nature of SES research, and the role played by open -access journals in the growth of SES research in the digital era. We further suggest that the SES research field is at a critical transition point, with contending visions of its future following a more disciplinary path or remaining as a more open interdisciplinary space. We conclude with the questions this raises for future SES research regarding the implications of this duality on the nature, production, and validation of knowledge and its evolution.</p
Decolonisation of nature in towns and cities of South Africa:
No full textWays 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
Never be silent : publishing & imperialism in Kenya, 1884-1963
No full textSocial communications are central to any social struggle. There is a sizable body of literature from other countries on the use of oral medium, newspapers, books and other forms of communications being used as tools for organising against a powerful enemy, as a training ground for cadres and for clarifying and developing revolutionary theory, ideology, organisation and practice. All this ensures a greater unity among those resisting oppression and exploitation. Thus revolutionary and liberation forces of Bolsheviks in the Soviet Union, the Communist Party of China, and in Vietnam had developed theories and practices of revolutionary publishing as part of their revolutionary work. This has also been the case during anti-colonial and anti-imperialist struggles in Africa, but very little of this has been systematically documented as an aspect of revolutionary communications policy and practice. While the
colonial communications systems have been reasonably well documented, the resistance communication systems remain largely undocumented and ignored. This book is an initial attempt to document this dynamic communications process in Kenya with its external struggles against colonialism and its complex internal struggles with overlaying divisions of race and class, Kenyan and foreign peoples. The main theme emerging from this experience is that people struggling to change their society always find ways of establishing their own system of communicating with the people they lead
and by whom they are led. Their mission of revolution, of change, of peace, of social and economic justice requires that they should never be silent. This was well understood and practised by the liberation forces in Kenya. They
were never silent
What are social-ecological systems and social-ecological systems research
No full textThe period since the Second World War has been marked by rapid and accelerating changes to many aspects of human society and the environment (Clark, Crutzen, and Schellnhuber 2004; Steffen et al. 2011; Steffen et al. 2015a). There is accumulating evidence and rising concern about the potential consequences these changes hold for key Earth system processes at a global scale, and human well-being and prosperity into the future (Krausmann et al. 2013; Steffen et al. 2015b). The Anthropocene, as this new era of extensive human impact on the Earth has come to be known (Crutzen 2006), manifests in a closely intertwined set of social and ecological changes. Technological advances, increasing human population, rising levels of wealth and consumption, and the institutional arrangements we have developed to govern our economies and societies interplay with one another, and drastically affect the Earth’s climate, biological diversity, fresh-water and biogeochemical flows, and levels of novel pollutants in the environment (Steffen et al. 2015a). These environmental changes, in turn, contribute to increasingly frequent and severe droughts (Dai 2013; Trenberth et al. 2014), floods (Milly et al. 2002; Nicholls 2004), heatwaves (Guo et al. 2018; Oliver et al. 2018) and the emergence of novel pathogens such as SARS-CoV-2 (Everard et al. 2020; O ’Callaghan-Gordo and Antò 2020; Schmeller, Courchamp, and Killeen 2020) that can lead to massive societal disruption and hardship, especially among the poor (Wheeler and Von Braun 2013; Barbier and Hochard 2018)
