Globally, indigenous knowledge (IK) has been shown to be a critical factor in economic growth and sustainable development and is as important as scientific knowledge. However, when it comes to the African narrative, IK research still seems to fall short, even with the great recognition and interest it is attracting. IK has always been underprivileged and marginalized, treated as an unsubstantiated type of knowledge that cannot provide any scientific solutions. Consequently, the aim of this paper is to provide an insight into the importance of IK research from a comparative African perspective from 1990 to 2020. The paper used a combination of bibliometric analysis and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) protocol to provide a comprehensive view of IK research. The VOSviewer software was used to provide a visualization of the bibliometric analysis through network maps. The findings suggest that while IK is a globally recognized concept, the African narrative is missing and not told by Africans. Most researched studies on IK in Africa are on ethnobotany, customs, traditions, agroforestry, and agriculture. Moreover, most of the IK research is from Southern Africa. There is a need for the integration of IK and scientific knowledge to develop well-informed approaches, methodologies, and frameworks that cater to indigenous communities and resilient ecological development. The research outcomes provide valuable insights for future research trends; they further highlight opportunities for building research partnerships for strengthening policy generation and implementation.

Landscape-change studies have attracted increasing interest because of their importance to land management and the sustainable livelihoods of rural communities. However, empirical studies on landscape change and its drivers are often poorly understood, particularly, in small rural communities in developing countries such as South Africa. The present study surveyed local community livelihoods and perceptions of landscape change in the Nzhelele and Levuvhu river catchments in Limpopo Province, South Africa. These areas have experienced land reform and are also characterized by environmental degradation, poverty, inequality and environmental justice concerns among other issues. Land-cover maps derived from Landsat satellite imagery were used for purposes of correlating and validating the survey data findings and results. The survey results showed that education levels, working status and marital status have statistically significant effects on community livelihoods (indicated by levels of income, p < 0.05). Maize, fruits and vegetables are the main cultivated crop varieties in the study area, and these crops are mainly used for subsistence to meet household self-consumption requirements. Moreover, local community members and stakeholders argue that the landscape has changed over the past 20 years mainly as a result of urban expansion, deforestation, agricultural diversification and forestry intensification. These landscape changes were largely confirmed by the land-cover change maps derived from satellite imagery. Soil erosion as a result of landscape changes was identified as a major threat and hazard in the study area. Political, natural, economic and cultural factors have been identified as the major underlying drivers for the observed landscape changes. These results have implications for understanding landscape change, coupled with human–nature relationships as well as informing government policy with respect to advancing land management and further promotion of the sustainable livelihoods of rural communities. Overall, the study proposes a multiple stakeholders’ approach and ecosystem-based approach to promote the sustainable management of landscapes in rural areas.

Little is known regarding landscape change, although the factors and implications of such changes are evident each day. Over the past decades rapid urban sprawl, urban land expansion, agricultural intensification and expansion of renewable energy use has had a negative impact on the environment and puts the sustainability of land at risk. This paper seeks to provide knowledge on global environmental change, landscape change and climate change and to identify the drives of landscape change and their implications. Moreover, the research study aims to provide data on the drivers that influence landscape change. It seeks to provide information on how land use change and landscape change in rural areas can be affected by factors such as urbanization, climate change and human activities (rivers, agriculture, deforestation and so forth). The study shall be focused on the Levuvhu and Nzhelele river catchment area, located within the Venda Region of the Limpopo Province in South Africa. Group focus discussions, field work and interviews were conducted to collect data with environmental, geography, landscape surveyors and the local ordinary residents within the areas. The results of the findings were assessed accordingly and provided to give a clear understanding of the importance of landscape change.
