“…Though several studies demonstrate that PES harvesting behaviour is influenced by different SEDs, such as (i) availability (Hora et al 2021), (ii) socio-economic factors, (iii) culture (Hora et al 2021), and (iv) species-level (Leaver and Cherry 2020), this study also found that the influence of a given socio-ecological factor was not consistent across the different distance regimes from the forest resources. Our finding implies that distance regimes may highly influence human behaviour in forest resource harvesting consistent with the Optimal Foraging Theory (Soldati et al 2017;Feitosa et al 2018). Our finding is consistent with Mohammed and Inoue (2017) who reported that as the distance from communities to the forest resources increases, there is less likelihood that communities will harvest the PESs at far distance depending on the prevalent socio-ecological factors that differ from one community to other.…”

“…Recently, many studies have applied the Optimal Foraging Theory (OFT) to disentangle the contribution of different socioecological determinants on user behaviour. The OFT suggests that human beings will maximise their gains, whether economic or energy demanding, when extracting PESs (Soldati et al 2017;Feitosa et al 2018). The theory is applied to understand the fundamental choices of foragers, such as where to forage, what to forage, and how long to spend foraging (Kefa et al 2018).…”

“…The foragers require time and energy to search for PESs, and the availability of resources influences the choice of the foraging site. This leads foragers to choose foraging sites that combine availability and quantity with minimal distance (Feitosa et al 2018). If foragers choose their foraging site based on the distance to the forest, perhaps to minimise the collecting energy and travelling time, distance becomes endogenous to PESs harvesting and use.…”

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.

“…Despite criticisms by some anthropologist that OFT is reductionistic and cannot account for the historical and socio-cultural factors that structure human societies (e.g., Ferguson 2016; Jones 2009; Meehan 1983; Soares Feitosa et al 2018), foraging models may be more relevant to human foragers than to other organisms precisely because of the human ability to process vast amounts of information about the environment, guiding people towards the optimal choice, thereby maximizing fitness (Smith 1983). Foraging models attempt to predict the optimum state under specified environmental conditions, which are then tested against behavior exhibited by particular organisms to determine the fit between observation and prediction (Kormondy and Brown 1998: 416).…”

Harvesting distance effect on tree species diversity in traditional agroforestry landscape: a case of Vhembe Biosphere Reserve in South Africa

Traditional agroforestry has been recognised to contribute to biodiversity conservation; however, biodiversity strategies often lack information about drivers of tree species diversity loss, which is crucial for decision-making. Anthropogenic disturbance has positive and negative effects on tree species richness and diversity. This study was conducted in Vhembe Biosphere Reserve, Limpopo Province, and used distance from the nucleus of the community to the forest as a parameter to assess tree species richness and diversity. Vegetation data were collected using three transects of 150 m in each distance level and sampled a total area of 1000 m2 by sampling five rectangular plots of 20 m2 × 10 m2 (200 m2). Data analysis was conducted using Chao1, PERMANOVA, nMDS, PERMDISP, DISTLIM, dbRDA and SIMPER. The findings are in consonant with distance decay of community similarity hypotheses, with estimated tree species richness of 76, 93 and 95 species in an immediate distance, intermediate distance and far distance, respectively. Moreover, the highest species variation was observed at an intermediate distance, which indicates that there is greater species composition at an intermediate distance compared to immediate and far distances. The results confirm that the distance and associated factors have major detrimental effects on tree species richness and biodiversity in traditional agroforestry landscapes. Harvesting of provisioning ecosystem services is found and known to be extremely high in the study area. Effective interventions such as planting indigenous trees and conserving the existing vegetation must be implemented to reduce and halt overexploitation.
