Article
Full-text available
Since the era of European exploration, the world has been conquered and nations subdued by imperial powers. The evidence of colonisation is explicitly seen in the territorial demarcations on the global map, borders that at times seem to follow little more than natural boundaries chosen to divide territories between competing powers. The borders tha...

Full-text available
Scholars are increasingly starting to engage in analysing non-use of social media among higher education students, but to date there lacks a framework within which to do so. Toward this end, this article identifies four key themes associated with not using social media to develop a typology of social media non-use. The themes are: 1) exclusion whic...

Full-text available
With ~70% of the sub-Saharan population living in rural areas, more than 90% of rural African households depend on natural forest products. Although several studies in other parts of South Africa have looked into the use of natural forest products in poverty alleviation, little is known on the roles and relative contribution of natural forest produ...
Article
Full-text available
Large wood deposited in rivers provides ecological benefits for multiple trophic groups, but public perceptions of these deposits can be varied. In particular, flooding experiences linked to large wood debris could influence how the public and stake-holders view large wood deposited into the river ecosystem. Here, we assessed the perceptions toward...
Article
Full-text available
Wetlands are amongst the world’s most important ecosystems, providing direct and indirect benefits to local communities. However, wetlands worldwide continue to be degraded due to unsustainable use and improper resource management. In this paper, we assess the perceptions, importance, management and utilisation of wetlands among local community mem...
Article

This paper lies at the intersection of discussions surrounding digitally mediated research methods and transnational research projects. It contributes to the current methodological debate surrounding online interviewing by focusing on tensions and affordances involved in Skype-to-phone interviewing in a transnational research context. While the Sky...
Article
Full-text available
Increased fishing pressure from artisanal and recreational fishing has led to the collapse of some important fish stocks around the world over the past years. There is currently limited understanding of the impacts of recreational and artisanal fishing on tigerfish Hydrocynus vittatus populations in Lake Kariba and the socioeconomic factors behind...
Article
Full-text available
Plastic pollution is a major global issue and its impacts on ecosystems and socioeconomic sectors lack comprehensive understanding. The integration of plastics issues into the educational system of both primary and secondary schools has often been overlooked, especially in Africa, presenting a major challenge to environmental awareness. Owing to th...
Article
Full-text available
It was with eagerness that we received a response to our original opinion piece entitled ‘Shifting sands: The decolonality of geography and its curriculum in South Africa’.1 This was composed as a way to engage in the debate around geography, its history, and where it currently stands in relation to student calls for its decolonisation. With this d...
Chapter
Full-text available
Many who venture into the city, especially in the global South, come into fulfil their developmental needs, find employment, and earn a liveable income. Many who arrive in these urban areas must contend with a heightened concern over crime and violence. Inequalities exist in the fear of personal safety across different genders, different socio-econ...
Article
Full-text available
Access to education is a significant determinant in future success, not only for a country but equally for individuals. Higher Education (HE) thus is an integral part of the Sustainable Development Goals and vital in supporting African development. Despite this, there is often a lack of access to HE in many parts of Africa, distance education can s...
Article
Full-text available
The capacity of agriculture to provide sustainable livelihood opportunities is exceeded by the rural populations of developing countries, and with limited opportunities available in urban centres, the rural non-farm economy (RNFE) becomes pivotal in improving rural livelihoods. Within an empowerment agenda, it is important for policy makers to unde...
Article
Full-text available
Much research in face-to-face contexts outlines the importance of early adjustment on students' higher education experiences. However, few studies have replicated this research in distance learning contexts to unpack the early multifaceted adjustments associated with studying in absence of a physical campus. This is particularly needed from a Globa...
Article
Full-text available
Much of the research on how social media is embedded into the educational practices of higher education students has a Western orientation. In concentrating on a case study of the varied ways in which African International Distance Education (IDE) students actively use social media to shape their learning experiences, we discuss an under-researched...
Article
Full-text available
The global knowledge economy continues to be dominated by the Global North. Reasons may include a lack of proper national government support and funding and academic prowess on the part of scholars in the Global South. However, focusing on only these largely technical and economic reasons, whilst ignoring the greater cultural and political reasons...
Article
The authors regret that an error occurred in the address of one authors: Dr. Ryan J Wasserman, it was reported at as “South Africa Institute for Aquatic Biodiversity” instead of “South African Institute for Aquatic Biodiversity” (Dalu et al., 2017). We apologize for this error and possible misleading to our readers and the South African Institute f...
Article
Full-text available
Rapid and widespread land cover change and the subsequent loss of the buffering capacity provided by healthy ecosystems against natural hazards has resulted in increased vulnerability to natural hazards. There is an insufficient understanding of natural resource contribution to the resilience of poor urban communities living in informal settlements...
Article
Full-text available
Patterns of land use, household topographical location and state of natural vegetation influence the spatial distribution of flooding impact. Using field observations and GIS mapping techniques, we investigated how landscape factors influenced structural flooding impact in informal settlements. This study was carried out in the informal settlements...
Article
Full-text available
Amidst the socio-economic meltdown in Zimbabwe, increased illegal mining activities on recently discovered diamond and gold deposits have given local people a source of livelihood. The problem of illegal gold mining is fast spreading through the Eastern Highlands and other parts of the country, as hundreds of artisanal gold miners swarm to the area...
Article
Full-text available
Controlled small-scale fires are traditionally used in the African savannah to flush out small mammals for hunting. Poachers in Zimbabwe are carelessly deploying crude versions of this practice, causing unmanageable bush fires and large-scale destruction.
Article
Full-text available
In this study, we assessed direct or indirect community livelihoods impacts on the preservation of Potamonautes spp., in the Eastern Highlands region of Zimbabwe and attempted to identify opportunities and constraints to conservation of crabs within the pre-existing livelihoods of community households. Random and snowball sampling methods were used...
Article
Full-text available
Understanding the drivers of community structure is fundamental for adequately managing ecosystems under global change. Here we used a large dataset of eighty-four headwater stream sites in three catchments in the Eastern Highlands of Zimbabwe, which represent a variety of abiotic conditions and levels of impairment, to examine the drivers of benth...
Article
Full-text available
In developing countries, mobilisation of capital to meet power and energy infrastructure needs is often executed to facilitate short term goals without adequate considerations for the human and natural environment. Here we outline, using an example, how such unbalanced approaches can result in the creating of social traps for nearby communities. Th...
Article
Full-text available
Ephemeral systems are unique environments that function in a fundamentally different way to permanent waterbodies. Ephemeral wetlands in arid regions are often degraded or destroyed through poor land-use practice long before they are ever studied or prioritized for conservation. Climate change will likely also have implications for these ecosystems...
Article
Full-text available
The current nature and challenges of urbanisation in sub-Saharan Africa display several unique features only weakly evident on other continents. Key ones include the current high rates of population growth, inadequate planning and governance systems, concentration in small and medium-sized towns, and increasing urban poverty. These shape the extent...
Article
Full-text available
Research into the benefits that ecosystems contribute to human wellbeing has multiplied over the last few years following from the seminal contributions of the international Millennium Ecosystem Assessment. In comparison, the fact that some ecosystem goods and services undermine or harm human wellbeing has been seriously overlooked. These negative...
