Coping strategies and risk manageability: using participatory geographical information systems to represent local knowledge

The accumulated knowledge and perceptions of communities 'at risk' are key elements in managing disaster risk at the local level. This paper demonstrates that local knowledge of flood hazards can be structured systematically into geographic information system (GIS) outputs. When combined with forecasting models and risk scenarios, they strengthen the legitimacy of local knowledge of at-risk populations. This is essential for effective disaster risk reduction practices by external actors, local non-governmental organisations (NGOs) and municipal authorities. The research focused on understanding coping strategies and 'manageability' of flood hazards as defined by communities. 'Manageability' is how people experience flooding in relation to their household capacity and the coping mechanisms available. The research in the Philippines highlights the significance of localised factors, including socioeconomic resources, livelihoods, seasonality and periodicity, for understanding manageability. The manageability concept improves practice at the municipal level by legitimising local coping strategies, providing better indicators, and developing understanding of flooding as a recurrent threat.     

Factors influencing local ecological knowledge maintenance in Mediterranean watersheds: Insights for environmental policies

Local ecological knowledge (LEK) has been found to be one of the main bridges to manage biocultural diversity. We analyzed the factors affecting LEK maintenance and transmission in a Mediterranean watershed. We used a mixed methods approach to evaluate the agricultural LEK in three different dimensions: biological, soil and water management, and forecasting. We found that the main factors for its maintenance were the respondent''s time living in the area and the social relationships established among farmers, which involved partner collaboration and farmer information exchanges. Protected areas also played a key role for maintaining the LEK associated with soil and water management. Finally, we found that outmigration and mechanization were the most important indirect drivers of change underlying LEK erosion. We suggest that environmental policies should focus on promoting this experiential knowledge, considering both intergenerational renewal and the gendered aspects of this knowledge.

The gulf of cross-disciplinary research collaborations on global river basins is not narrowed

Using publications in the Web of Science database (WoS), this study investigates the research collaboration on the top 95 most researched global river basins since 1900. The links of both the disciplines involved and the management issues studied between the biophysical, economic, societal, climatic and governance sub-systems of these river basins were examined. We found that research collaborations were dominated within the biophysical sub-system (65.3%) since the knowledge predevelopment period (1900–1983), with continuous increases (by 18.5%) during the rapid development (1984–2000) and the stabilisation (12.9% increase) (2001–2017). However, research collaborations related to the societal sub-system remained marginalised (varied at about 1%), while those related to the governance sub-system expanded in issues studied (32.8%) but were not supported by the core governance disciplines (3.4%). The key findings explained why global river basins are degraded from the perspective of knowledge development and they can assist the strategic planning and management of scientific research for improving governance capacity in modifying the relationship between human and nature on river basins in the Anthropocene. Tackling challenges in the Anthropocene requires transformation of the current pattern of knowledge development, a revolution in the governance of science.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-022-01716-0.

Shared ways of thinking in Brazil about the science–practice interface in ecology and conservation

The debate in the literature on the science–practice interface suggests a diversity of opinions on how to link science and practice to improve conservation. Understanding this diversity is key to addressing unequal power relations, avoiding the consideration of only dominant views, and identifying strategies to link science and practice. In turn, linking science and practice should promote conservation decisions that are socially robust and scientifically informed. To identify and describe the viewpoints of scientists and decision makers on how the science–practice interface should work in order to improve conservation decisions, we interviewed Brazilian scientists (ecologists and conservation scientists, n = 11) and decision makers (n = 11). We used Q methodology and asked participants to rank their agreement with 48 statements on how the science–practice interface should work in order to improve conservation decisions. We used principal component analysis to identify shared viewpoints. The predominant viewpoint, shared by scientists and decision makers, was characterized by valuing the integration of scientific and strategic knowledge to address environmental problems. The second viewpoint, held mostly by decision makers, was distinguished by assigning great importance to science in the decision-making process and calling for problem-relevant research. The third viewpoint, shared only by scientists, was characterized by an unwillingness to collaborate and a perception of scientists as producers of knowledge that may help decision makers. Most participants agreed organizations should promote collaboration and that actors and knowledge from both science and practice are relevant. Disagreements concerned specific roles assigned to actors, willingness to collaborate, and organizational and institutional arrangements considered effective to link science and practice. Our results suggest there is ample room for collaborations and that impediments lie mainly in existing organizations and formal institutional arrangements rather than in negative attitudes between scientists and decision makers.     

Racial disparities in parent knowledge of concussion and recognition of signs and symptoms

Introduction: Concussion is a type of traumatic brain injury that can be sustained through participation in different sports. It is important that a parent be able to identify common and uncommon symptoms of a concussion to ensure the safety and good health of their child. The purpose of this study was to compare knowledge of concussion scores among White and African American parents and guardians. Methodology: This cross-sectional study consisted of a single survey of 53 questions that was given to parents/guardians of high school athletes at a preseason parent meeting. Parent and guardian knowledge of concussion was assessed through a series of 45 questions. Participants were asked to correctly identify signs and symptoms of concussion, answer questions regarding the anatomy of a concussion (i.e. a concussion is an injury to the brain), answer true/false questions about general concussion knowledge, select from a list the consequences of multiple concussions and select from a list the consequences of returning to play too soon from a concussion. Knowledge of concussion was calculated by summing correct responses for the 45 knowledge questions. Racial differences were calculated using an ANCOVA, controlling for socioeconomic school type. The statistical significance level was set a priori p ≤ 0.05 for all analyses. Results: Participants of this study consisted of 176 [115 (65.3%) White, 61 (34.7%) African American] parents/guardians of high school athletes. Significant differences in knowledge of concussion scores between White parents/guardians [38.50 ± 4.55 (85.6% correct)], and African American parents/guardians [35.15 ± 4.97, 78.1% correct)] were identified (F_(1,172) = 4.82, p = 0.03). Conclusion: Knowledge of concussion disparities exist between African American and White parents/guardians. This disparity could cause complications from concussion to surface among children and adolescents participating in sport as their parents/guardians may not be able to correctly identify the signs and symptoms in order to seek proper medical care. Practical Application: Findings from this study highlight quantitative differences in concussion knowledge of parents from different demographics. These findings underline disparities and inequities in access to concussion-health resources that need to be addressed.
