Despite a growing interest in interdisciplinary research, systematic ways of how to integrate data from different disciplines are still scarce. We argue that successful resource management relies on two key sources: natural science data, which represents ecosystem structure and processes, social describes people's perceptions understanding. Both vital, mutually complementing information sources can underpin the development feasible effective policies interventions. To harvest added value combined knowledge, uniform scaling system is needed. In this paper, we propose standardized methodology connect explore types quantitative sciences reflecting temporal trends quality. demonstrate with such as fisheries stocks mangrove cover one hand community's other.

Water quality is an integral part of water security. Measuring the physico-chemical indicators for can provide objective picture health, but it does not information on lived experiences related to quality, expectations resources, nor how affects its usage. Perceptual and traditional ecological knowledge help understand interactions between people, thereby support locally appropriate sustainable resource strategies. Accordingly, our project sought collect synthesise insights from local perspectives in upper Santa River basin, Peru, a region where directly relates people's livelihoods. data was collected via Nuestro Rio mobile app (N = 149) as well walking interviews (n 84) (July-August 2021) two main study areas, Olleros Catac. We find that differ within, between, areas communities, however four overarching themes were identified, are explored here: i) environmental quality; ii) uses; iii) perceived causes iv) perceptions behind emotions. Most rural participants felt cause poor mineral pollution, likely linked geology, we also found depend usage, domestic use agricultural Qualitative highlighted complex relationships More inclusive citizen-based science considers what people observe, think feel about their rivers much deeper contextual understanding dynamic human-water systems, with further benefits improving management policy implementation.

This paper examines the spatial relationships between biophysical social sequestration potential (measured as dioxide, CO 2 , flux) Helsinki, Finland, using integrated valuation. The approach combines methods from modelling, expert scoring approaches assessment public participation geographic information (PPGIS). Results indicate strong associations of flux priorities, weaker values.

Abstract Social‐ecological systems like fisheries provide food, livelihoods and recreation. However, lack of data its integration into governance hinders their conservation management. Stakeholders possess site‐specific knowledge crucial for confronting these challenges. There is increasing recognition that Indigenous local (ILK) valuable, but structural differences between ILK quantitative archetypes have stalled the assimilation management, despite acknowledged bias uncertainty in scientific methods. Conducting a systematic review fisheries‐associated research ( n = 397 articles), we examined how accessed, applied, distributed across space species, has evolved. We show generated qualitative, semi‐quantitative information diverse taxa 98 countries. Fisheries‐associated mostly targets small‐scale artisanal fishers (70% studies) typically uses semi‐structured interviews (60%). revealed large variability sample size 4–7638), predicted by approach employed (i.e. qualitative studies target smaller groups). Using thematic categorisation, scientists are still exploring techniques, or ‘validating’ through comparisons with (20%), recording what understand (40%).

Such approaches facilitate insight management fall short accepting as valid complementary way knowing about systems. This synthesis reveals development increased opportunities needed bridge data.

Abstract Embracing local knowledge is vital to conserve and manage biodiversity, yet frameworks do so are lacking. We need understand which, how many holders needed ensure that management recommendations arising from not skewed towards the most vocal individuals. Here, we apply a Wisdom of Crowds framework data-poor recreational catch-and-release fishery, where individuals interact with natural resources in different ways. aimed test whether estimates fishing quality diverse groups (multiple ages years experience), were better than provided by homogenous thresholds exist for number capture estimates. found diversity matters; using random subsampling combined saturation principles, determine targeting 31% survey sample size captured 75% unique responses. Estimates small subsets this outperformed groups; sufficiently crowds just as effective large estimating ecological state. advocate more research application.
