Determinants of participation in rural non-farm economy in Zvimba District, Zimbabwe

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 understand why households enter into the RNFE. We investigated participation in the RNFE of farm worker livelihoods along with the motivation for participation in RNF employment. Moreover, we sought to determine the key barriers and enablers to the adoption of high return strategies in RNFE activities by rural farm workers in Zimbabwe. Quantitative household surveys and qualitative focus group discussions were used to investigate levels of household dependency, education and skills, income accumulation and enterprising, expenditure and household assets. Our results showed that the primary motivation for entry into the RNFE was distress-pushed diversification. Our study found that market dynamics, limited skills, education level, and lack of capital are the paralysing factors towards significant income returns from RNFE for households. This information is critical for policy development for sustainable rural livelihoods, especially for rural farm workers who constitute the most vulnerable of the entire African rural population

Contribution of Natural Forest Products to Rural Livelihoods at Mavunde and Sambandou Villages, Vhembe Biosphere Reserve, South Africa

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 products as daily and safety nets specifically within the Vhembe Biosphere Reserve, South Africa. This study assessed the different roles played by natural forest products in households and the patterns of their relative contribution to households both as sources of income and direct consumption within differing household compositions as well as socio-economic factors. These included employment and income diversification role and the monetised value of natural resources in the rural livelihoods of households in Sambandou and Mavunde, Vhembe Biosphere Reserve, Limpopo Province, South Africa. The study inter alia compared a wide use of natural resources by two villages and determined on which forest products they most relied for their economic welfare. Their relative contributions to livelihoods were assessed by identifying factors that affected their contributions. Findings of the study showed that Sambandou had a high number of people with formal jobs and females, and fewer old-age pensioners. Differences in employment and education between villages were observed. In all villages, the most frequently used or harvested resource was fuelwood, wild edible fruits, herbs, grass/shrub hand sweepers, insects for food, thatch grass/reeds and poles for fencing and housing. Overall, Mavunde village households were found to be more dependent on natural resource harvesting both for income and subsistence substitution. Findings suggest that this may have been a consequence of socio-economic factors such as income and employment, as well as general underdevelopment in the village. This study’s findings could contribute to further studies into how these results compare to other parts of the country and region, as well as their respective developmental implications

Understanding communities’ perceptions, demographics and uses of wetlands in Vhembe Biosphere Reserve, South Africa

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 members using a household questionnaire and field observations within the seven Thulamela municipality wetlands, Vhembe Biosphere Reserve in South Africa. Seven wetlands were chosen for the study, with 140 household respondents randomly selected for a questionnaire survey. The study indicated that wetlands were beneficial in supporting local communities through resource provisioning. The unemployment rate and household respondents’ income were the main contributors to increased wetland dependency and utilisation. We found that urban and rural developments, unregulated use and extensive agricultural practices (i.e., cultivation, livestock grazing) have resulted in wetland degradation. We observed that the local communities around the wetlands were interested in the benefits they receive from wetlands when compared to their conservation. Furthermore, the study observed poor wetland co-management or collaboration among the local stakeholders. This has resulted in a lack of openly known, active platforms to discuss wetlands management issues. These results highlight that centralized, top–down approaches to wetland use are insufficient for maintaining and managing wetland ecosystems, posing a challenge to sustainable wetland management. Therefore, there is a need to develop a shared understanding through bottom-up approaches to wetland management nested within national regulatory frameworks, ideally combined with awareness building and knowledge sharing on ecological benefits and management of wetlands

An assessment of chlorophyll-a concentration spatio-temporal variation using Landsat satellite data, in a small tropical reservoir

Publisher versionTraditional approaches to monitoring aquatic systems are often limited by the need for data collection which often is time-consuming, expensive and non-continuous. The aim of the study was to map the spatio-temporal chlorophyll-a concentration changes in Malilangwe Reservoir, Zimbabwe as an indicator of phytoplankton biomass and trophic state when the reservoir was full (year 2000) and at its lowest capacity (year 2011), using readily available Landsat multispectral images. Medium-spatial resolution (30 m) Landsat multispectral Thematic Mapper TM 5 and ETM+ images for May to December 1999–2000 and 2010–2011 were used to derive chlorophyll-a concentrations. In situ measured chlorophyll-a and total suspended solids (TSS) concentrations for 2011 were employed to validate the Landsat chlorophyll-a and TSS estimates. The study results indicate that Landsat-derived chlorophyll-a and TSS estimates were comparable with field measurements. There was a considerable wet vs. dry season differences in total chlorophyll-a concentration, Secchi disc depth, TSS and turbidity within the reservoir. Using Permutational multivariate analyses of variance (PERMANOVA) analysis, there were significant differences (p < 0.0001) for chlorophyll-a concentration among sites, months and years whereas TSS was significant during the study months (p < 0.05). A strong positive significant correlation among both predicted TSS vs. chlorophyll-a and measured vs. predicted chlorophyll-a and TSS concentrations as well as an inverse relationship between reservoir chlorophyll-a concentrations and water level were found (p < 0.001 in all cases). In conclusion, total chlorophyll-a concentration in Malilangwe Reservoir was successfully derived from Landsat remote sensing data suggesting that the Landsat sensor is suitable for real-time monitoring over relatively short timescales and for small reservoirs. Satellite data can allow for surveying of chlorophyll-a concentration in aquatic ecosystems, thus, providing invaluable data in data scarce (limited on site ground measurements) environments
