“…Building on community knowledge is also an entry point for establishing management intervention through identification of different interests on the use of ecosystems. This could help to balance trade-offs in ecosystem services and encourage activities that build on multifunctional landscapes and sustainable use of natural resources [42,43]. The present study explored how local communities in the Rufiji Delta perceive a multitude of ecosystem services provided by mangroves and factors influencing on their perception.…”

Understanding how local communities perceive and depend on mangrove ecosystem services (MES) is important for translating and incorporating their benefits, priorities, and preferences into conservation and decision-making processes. We used focus group discussions, key informant interviews, household questionnaires, and direct observations to explore how local communities in the Rufiji Delta perceive a multitude of MES and factors influencing their perceptions. Sixteen MES were identified by the respondents. Provisioning services were the most highly identified services, accounting for 67% of the overall responses, followed by regulating (53%), cultural (45%), and supporting (45%) services. Poles for building, firewood for cooking, coastal protection, and habitats for fisheries were perceived as the most important MES to sustain local livelihoods, although the perceptions differed between sites. Distance from household homes to mangroves and residence time were significant predictors of the local communities’ awareness of all identified MES. Gender of household heads and performance of local management committees also determined the local communities’ awareness of provisioning, regulating, and cultural services. We conclude that perceptions of MES are context-specific and influenced by multiple factors. We believe a deeper understanding of local stakeholders’ preferences for MES can help strengthen the link between local communities and conservation actors and can provide a basis for sustainable management of mangrove forests.

“…Catfish species (Siluriformes) are very important target species for fisheries and aquaculture in South-east Asia. Catfish aquaculture is one of the most developed socioeconomic sectors in this area, relying upon only two freshwater species from the Pangasiidae family: Pangasianodon hypophthalmus, the striped catfish or sutchi catfish, and Pangasius bocourti, the basa catfish (Halls and Johns 2013;Quyen et al 2017). In the Mekong River basin, wild catfish are an important resource for income and food for local populations.…”

Pangasius krempfi is a commercially important catfish in the Mekong River and is believed to migrate along the Mekong River basin. To verify this migration, elemental concentrations were measured in the water and in otoliths to infer the salinity of the water through the fish’s lifetime. In 2017, eight element concentrations were measured along the Mekong Delta using solution-based inductively coupled plasma mass spectrometry (ICP-MS). Concentrations of Sr, Li and Rb were strongly and positively correlated with salinity. Otoliths were taken from P. krempfi caught in the brackish waters of the lower Mekong Delta and seven element:Ca ratios were measured from the core to the otolith edge using laser ablation ICP-MS. The Sr:Ca, Ba:Ca, P:Ca and Mn:Ca ratios varied through the lifetime of the fish, but only Sr:Ca was suitable for estimating ambient salinity. The Sr:Ca profiles in otoliths were analysed and significantly correlated between individuals, with all fish hatched in water with very low levels of salinity, indicating a single freshwater spawning ground, and then living in waters with higher salinity, with two types of migration behaviour. Some individuals may return to low-salinity waters when older. These conclusions were supported by the Ba:Ca and Mn:Ca ratios. These migration patterns may have implications for fishery management.

“…Well-designed, integrated measures of ecosystem features directly relevant to the self-perceived well-being of stakeholders have been shown to influence perceptions of and desires for future community development ( Quyen et al 2017 ). While original research in the natural and social sciences tends, by design, to generate narrowly delimited data, a nuanced understanding of particular ecosystem goods and services often demands indicators composed of agglomerations of data from multiple sources ( Tran et al 2005 ).…”

The last decade has seen a proliferation of studies describing the benefits people accrue from natural processes by translation of spatially explicit land use and landcover data to ecosystem service provision. Yet, critical assessment of systemic bias resulting from reliance on land use and landcover data is limited. Here, we evaluate an extensive collection of ecosystem service‐related data based on land use and landcover according to a broadly applicable ecosystem service framework—Final Ecosystem Goods and Services (FEGS). In this framework, ecosystems are viewed from the perspective of a comprehensive set of beneficiaries and the biophysical features directly relevant to each. In this examination, we create a database identifying over 14,000 linkages between 255 data layers from EnviroAtlas and FEGS beneficiaries. Through these linkages, we identify major gaps in beneficiary identification and systemic biases resulting from the utilization of translations from land use and landcover data. Importantly, we find that for many beneficiaries there is an absence of data on FEGS at extensive scales in the United States. We provide a roadmap for the integration of extant ecosystem service research efforts using the FEGS classification scheme and critically appraise this scheme, highlighting inconsistent specification among beneficiary categories and environmental classes. We also explore the benefits of crosswalking different ecosystem service data and frameworks for researchers, by reducing the otherwise high buy‐in cost of data exploration, and for data developers, by increasing the exposure of their work.
