Feedbacks and Trade-Offs in the Use of Wetland Ecosystem Services by Local Communities in Rural Zimbabwe

Abstract

Rural wetlands, especially in developing countries, have been exploited for different ecosystem services because they are considered safety nets for food production and are important for livelihood strategies and human wellbeing. However, there are gaps in knowledge of the ecosystem services provided by small, valley bottom wetlands, especially in dryland areas and how these services are used and managed by local communities. This study focuses on the ecosystem services of valley bottom wetlands in Zindi, the Honde Valley, in rural eastern Zimbabwe. Ethnographic observations of wetland users’ activities and individual interviews with local residents and village heads were undertaken in this study, focusing on how people make use of the different ecosystem services that are derived from these wetlands. Results show that the wetlands are mainly utilised for provisioning services, but that these are related to the availability and properties of supporting and regulatory services in the wetland environment. All of these services are also strongly mediated by the traditional cultural contexts and values held by local communities. The results show that the exploitation of some ecosystem services leads to negative impacts on the availability or properties of others, and this means that there are trade-offs in the uses and management by individuals and communities as a whole. These feedbacks and trade-offs are not well explored in most studies but are critical in considering community responses to changing wetland resources, in particular under climate change. This study recommends that policymakers should include small and often hitherto overlooked wetlands in their management plans, since they are critical for supporting rural livelihoods. It is also important that wetland management plans aim to improve the range and sustainability of ecosystem services available and avoid the need for unnecessary trade-offs in their use by local communities.

Traditional Knowledge of Marine Resources and Its Impact on the Well-Being of Coastal Communities in Peninsular Malaysia

“…Apart from that, the development of traditional medicine is also an innovative way to reduce poverty and improve public health through its human and environmental integration that can be developed by responsible parties [17]. This is similar to a study conducted in Africa that reported the consumption of foods and other goods derived from the sea, as well as the usage of marine-based resources, will inadvertently assist in the improvement of local communities' means of subsistence and available healthcare options [18].…”

Traditional Knowledge of Marine Resources and Their Relations to the Coastal Community’s Economic Well-Being in Peninsular Malaysia

“…Nevertheless, coastal areas, particularly in developing countries, have been unscrupulously exploited since they are viewed as safety nets for food production and to provide for livelihood and economic well-being [19]. "Economic wellbeing" is defined by the Council on Social Work Education as having financial security in the present and the future [20].…”

Fostering sustainable practices in Zimbabwean tourism for firewood energy sustainability and efficiency amid costly renewables, weak policies, scarce electricity, and extensive deforestation

“…There have been calls for stronger legal enforcement, training programs, and incentives to promote sustainable energy transitions and supply chains in Zimbabwe's tourism enterprises (de Almeida et al, 2022;Muzamwese, 2023). With energy access essential for poverty reduction, Zimbabwe faces hard tradeoffs balancing livelihoods, conservation, and sustainable firewood use (Mandishona & Knight, 2022;Matsvai, 2018;Ngadze, 2023). This will require integrated land use policies and incentives that engage tourism supply chain and firewood-reliant households in sustainable forest management (Ignaciuk et al, 2023;Njenga et al, 2023).…”
