Abstract The integration of physical and social science data can enable novel frameworks, methodologies, innovative solutions important for addressing complex socio-environmental problems. Unfortunately, many technical, procedural, institutional challenges hamper effective integration—detracting from interdisciplinary research broader public impact. This paper reports on the experiences integration, as experienced by diverse Early Career Researchers (ECRs), offers strategies coping with these challenges. Through a workshop convened National Center Atmospheric Research (NCAR) Innovator Program, 33 participants different disciplines, career stages, institutions across United States identified four thematic related to complexity uncertainty, communication, scale, barriers. They further recommended individual, departmental, scale responses cope address These recommendations seek inform faculty department support ECRs, who are often encouraged—and even expected—to engage in integrative, problem-focused, solutions-oriented research.

Abstract Social sciences are increasingly recognized as significant for building a sustainable world since the social perspective can assist researchers in other fields navigating public controversy and designing more responsible interaction mechanisms between natural systems. However, question arises: to what extent do rely on science research their studies? Examining life publications from seven PLoS journals, this paper attempts characterize volume trajectory of citations sciences. We explore three core questions: To cite sciences? What actors citing Which being cited? Our analysis estimates influence 15%–19% publications, contributing 1.1%–1.5% references 2018. citers found across peripheral central topics disciplines.

Abstract Society relies on intact marine ecosystems for ecosystem services such as nutrition, livelihoods, health and well‐being. Yet, to obtain these benefits, we carry out activities, introducing pressures ecosystems, damaging degrading habitats reducing their capacity optimally provide services. Biodiversity are consequently being lost globally but impact chains from activities poorly understood, especially in tropical ecosystems. We identified the first time linking with they introduce five coastal habitats, specifically through application four Southeast Asian case study sites. Using expert elicitation based existing evidence, weighted each chain according pressure extent, frequency persistence, habitat resistance resilience. Assigning an risk score allowed identification of most risk, under threat. Of 26 considered, found fishing trawling, gill nets seine along tourism recreation.

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%).

Abstract. Research around water security in the Peruvian Andes rarely includes a local perspective or engages participatory approach with communities within research process. Here we share four key lessons from an interdisciplinary project that gathered community perspectives on quality issues upper Rio Santa basin. Mixed-methods data was collected via photo elicitation app survey (Nuestro Rio), and field work campaign. Our main learnings were i) importance of in-person engagement; ii) accessibility technology for collection; iii) need co-produced knowledge solutions; iv) complexity as environmental concept. highlights effective participant engagement methods to support socio-environmental integration sustainable decision-making resource management.
