“…These harvesting behaviours may lead to a high incidence of forest degradation in the proximate forest, and degraded forests would impede the rural people's livelihood. The rate of fuelwood extraction in southern Africa is unsustainable (Rasimphi and Tinarwo 2020). The findings of this study demonstrate that, although OFT may be used as a guide, the local level SEDs need to be integrated with conservation strategies and the sustainable harvesting practice in the TAL.…”

Traditional agroforestry landscapes play a critical role in conserving biodiversity and sustaining rural livelihoods through multiple products and services. However, an unprecedented rise in the unsustainable utilisation and management of provisioning ecosystem services from these landscapes contributes to forest biodiversity loss and impacts livelihood efforts. The objective was to evaluate the link between distance and socio-ecological determinants and the provisioning ecosystem services consumption behaviour. This study tested whether "rural people's preferences and extent of PESs harvesting decrease as the distance from the village to forest patches increase, regardless of the prevalent socioecological conditions'. Using a structured questionnaire survey, data were collected in 882 households in four villages of Thulamela Municipality, Limpopo Province in South Africa. The data were analysed using Chi-square, Fidelity level, Use-value, Friedman test, and Generalised linear model. Consistent with the hypothesis, the results showed that local people harvest most of the provisioning ecosystem services at an immediate (1 st ) level, followed by intermediate (2 nd ) and far distance (3 rd ) levels. This study further revealed the existence of 108 useful tree species in the study areas. This study also found that although socio-ecological determinants influence consumption behaviour, the influence of specific socio-ecological determinants was not consistent across the different regimes of distance from the forest resources. The fact that there is a preference to use and harvest provisioning ecosystem services from the distance regime closest to the household, shows a concerted effort to conserve and enhance the abundance of multipurpose tree species in homesteads and the immediate areas.

“…In another example, a study by ref. [54] in rural Vhembe District in the Limpopo Province of South Africa estimated the following animal populations: 1,050,685 cows with an estimated 12 kg of manure per animal per day, equivalent to an estimated 0.2 Nm 3 of methane per day; 373,037 pigs (5 kg/animal, 3.6 Nm 3 methane); 1,542,903 chickens (0.08 kg/animal, 0.35 Nm 3 methane); 253,139 sheep (6 kg/animal, 0.053 Nm 3 methane), and 1,147,987 goats with an estimated 6 kg manure output per animal and an estimated equivalent of 0.367 Nm 3 of methane per day. Assuming these numbers to be representative of approximate animal populations in all of South Africa's provinces, they represent huge renewable energy resources that have the capacity to confine South Africa's energy deficiency to history if utilised for biogas generation.…”

Energy availability is a pivotal driver in fostering sustainable socio-economic development. However, sub-Saharan Africa (SSA) grapples with paradoxes headlined by abundant energy resources but with the world’s lowest access to clean energy index per capita. Faced with a lack of access to clean energy sources like electricity, rural areas in the majority of SSA countries almost exclusively depend on biomass-fuels, mostly fuelwood, leading to heightened respiratory health risks as well as environmental degradation and accelerated climate change. As an alternative, this review investigates the potential of animal manure as a sustainable energy resource for rural SSA households, emphasising its utilisation as a feedstock for biogas production using anaerobic digestor technology. Results show that despite the abundance of literature that reports on successes in lab-scale bioreactor optimisation, as well as successes in the initial rollout of biogas biodigester technology in SSA with the help of international collaborators, the actual uptake of biogas bioreactor technology by rural communities remains low, while installed bioreactors are experiencing high failure rates. Resultantly, rural SSA still lags significantly behind in the adoption of sustainable clean energy systems in comparison to rural communities in other regions. Among some of the hurdles identified as driving low technology assimilation are onerous policy requirements, low-level government involvement, high bioreactor-instalment costs, the lack of training and awareness, and water scarcity. Prospects for success lie in innovative technologies like the low-cost portable FlexiBiogas system and private–public partnerships, as well as flexible energy policy frameworks. Bridging the knowledge-implementation gap requires a holistic approach considering cultural, technological, and policy aspects.

“…On a positive note, biogas is formed during the anaerobic decay of organic wastes, where methane and carbon dioxide are produced. This resource can be utilised in lighting, cooking, and conversion to electricity (Rasimphi & Tinarwo, 2020). Negligence of hazardous waste has raised worldwide environmental concerns and unfavourable climatic conditions.…”

The predominance of unwanted materials lying fallow in the environment, and the availability of information on waste management, offer the opportunity to explore the use of these resources as sources of recovered material. Regulatory drivers aim to harmonise the recovery potentials of wastes, thereby reducing the volumes sent to landfill. In this vein, this paper investigates the emissions from municipal solid wastes, which can lead to major environmental impacts. This study assessed the influence of recovery efforts on solid waste management practices in Nigeria. This was done by examining available literature chronicling pollution from unregulated dumpsites which can bioaccumulate in the environment, causing climatic impacts. It was discovered that emissions from waste can impact soil, water, and air, thus contributing to greenhouse gas emissions. Many developed countries have recorded significant improvement in adopting treatment facilities that can enable them to meet up sustainable development goals. However, developing countries still need assistance in developing a sustainable waste management programme that can help change their lifestyle, thus improving the management of the waste they produce. It becomes imperative that making the right choices can change the consumption pattern, thus, reducing the influx of pollutants whilst fostering a clean environment. Thus, a high-level recovery of resources can secure a sustainable future and a healthy environment.
