Using expert informed GIS to locate important marine social-ecological hotspots

Catchment-Scale Participatory Mapping Identifies Stakeholder Perceptions of Land and Water Management Conflicts

Competing socioecological demands and pressures on land and water resources have the potential to increase land use conflict. Understanding ecosystem service provisioning and trade-offs, competing land uses, and conflict between stakeholder groups in catchments is therefore critical to inform catchment management and the sustainable use of natural resources. We developed a novel stakeholder engagement methodology that incorporates participatory conflict mapping in three catchments with a short questionnaire to identify the perceptions of 43 participants from four key land and water management stakeholder groups: environmental regulators, water industry practitioners, the farm advisor community, and academics. The participatory mapping exercise produced heat maps of perceived conflict and land use competition, providing spatial detail of the complex combination of land use issues faced by catchment managers. Distinct, localised hotspots were identified in areas under pressure from flooding, abstraction, and urbanisation; as well as more dispersed issues of relevance at the landscape scale, such as from farming, forestry, energy production, and tourism. Subsequent regression modelling linked perceived conflict to land cover maps and identified coastal, urban, and grassland areas as the most likely land cover types associated with conflict in the study catchments. Our approach to participatory conflict mapping provides a novel platform for catchment management and can facilitate increased cooperation among different catchment stakeholders. In turn, land and water management conflicts can be recognised and their underlying drivers and likely solutions identified in an effort to better manage competing demands on catchment resources.

Connectedness to nature: Mapping the role of protected areas

Connectedness to nature (CNT) is likely to be a strong influence on how local communities and stakeholders respond to designation and management of protected areas. This study explores relationships between CNT and location, using the Maltese Islands as a case study. The intensity of CNT, as expressed by a sample of household respondents across the islands (n = 401), was measured using the Nature Relatedness Scale (NRS). Respondents were also asked to indicate places that are significant for their own connection with nature. Results were mapped and analysed with respect to the location of two types of protected areas: Natura 2000 sites and Urban Conservation Areas. The bulk of special places of high CNT identified by respondents were located in or very close to Natura 2000 sites, regardless of respondents' place of residence and regardless of protected area size. Protected natural areas are therefore important loci of community attachment with nature. Managers of such sites can potentially leverage this attachment to enhance community engagement in conservation and to contribute to increased nature connectedness in the community. However, this study also noted a not-insignificant contribution to CNT from urban or non-protected sites, providing support for adoption of landscape approaches that focus holistically on spaces that provide a context for daily life.

Mapping wild seafood potential, supply, flow and demand in Lithuania

While member states have made a great effort into mapping ecosystem services (ES) in Europe, much work is still needed, especially in the marine domain. Difficulties in understanding the ecological functioning of marine ecosystem services (MES), together with the lack of administrative and technical resources, calls for the development of new assessment approaches. Even for the well-studied MES, the provision of wild seafood, few studies focus on mapping and mostly in a qualitative way by applying expert-based methods. This study aims to quantitatively map MES by developing new methodological frameworks for each of the components of the cascade model for wild seafood provision. The results showed a high potential of wild seafood provision in coastal areas, contrasting with offshore areas of the Exclusive Economic Zone (EEZ). Wild seafood is mainly supplied in the central part of the EEZ and is influenced by biological (e.g. sediments) and anthropogenic (e.g. shipping) factors. The flow was mapped using the location of first buying companies, restaurants, hotels, and supermarkets showing that the highest values were located in the urban areas. The coastal zone has a high flow as a consequence of the high density of fish selling points. The demand was mapped using the population density, number of tourists, and the fish consumption per capita; showing a high demand for fish products in urban as coastal areas. A validation step for the developed potential and supply, the analysis of the limitations and methodological considerations for all components, highlights the future data needs; showing decision-makers where to direct efforts. Mapping all components of wild seafood provision is critical to understand dynamics, the trade-offs associated, and its role in the socio-economic dimensions of coastal communities. This information can then be integrated into decision-making by showing the advantages in achieving a sustainable provision of wild seafood.

Understanding the determinants of GIT post-adoption: perspectives from Mozambican institutions

This study aims to understand the determinants of geographical information technologies at the scale of post-adoption use and intention to increase the level of use in Mozambican institutions. Three known theories (diffusion of innovation theory, technology - organisation - environment framework, and institutional theory) have been used in order to accomplish the study. The data analysis showed that the variables compatibility, geographical scope, expansion opportunities, and normative pressure contribute to explaining GIT use. Relative advantage, complexity, coercive pressure, and mimetic pressure contribute to explaining the intention to increase GIT levels of use. The model revealed substantial power of explanation for GIT post-adoption.

Understanding the spatial diversity of social uses, dynamics, and conflicts in marine spatial planning

Marine coastal environments are often socially complex public areas that need equitable spatial planning approaches. Understanding the extent of extractive and non-extractive uses and the social dynamics that may be driving patterns of use is essential if the spatial plan is to support the social resilience of a marine area. In this study, a combination of fuzzy-set multi-criteria GIS modelling and negative tie social network analysis were used to explore social uses and conflicts based on sketch-mapping interviews with five key stakeholder groups (ecotourism, Aboriginal Traditional Owners, commercial and recreational fishing, and water sports) within a Marine Protected Area (MPA). Most of the areas within the MPA were regularly used by the stakeholders, with non-extractive and extractive stakeholders occupying similar spatial extents, with each stakeholder group having a different pattern of use. However, stakeholder groups had different levels of perceived priority to access these areas and support of the current spatial management plan, especially within the ecotourism and Aboriginal Traditional Owner groups. The investigation of social conflicts in shaping patterns of use revealed that most stakeholder conflicts do not necessarily occur in areas of overlaps, but generally in areas of high biodiversity and easy access through marine infrastructure. Ecotourism groups had the most perceived conflicts over marine space, which shaped their use towards certain no-take zones that protected high biodiversity and would also provide protection from other conflicting stakeholder uses (e.g., boating, fishing). Overall, the method outlined in this paper presents a way for marine spatial management to consider not only the extent and diversity of social uses in a marine environment but also the spatial-social dynamics that may determine the success of the spatial plan in supporting long-term social resilience.

Determining the Mechanisms that Influence the Surface Temperature of Urban Forest Canopies by Combining Remote Sensing Methods, Ground Observations, and Spatial Statistical Models

The spatiotemporal distribution pattern of the surface temperatures of urban forest canopies (STUFC) is influenced by many environmental factors, and the identification of interactions between these factors can improve simulations and predictions of spatial patterns of urban cool islands. This quantitative research uses an integrated method that combines remote sensing, ground surveys, and spatial statistical models to elucidate the mechanisms that influence the STUFC and considers the interaction of multiple environmental factors. This case study uses Jinjiang, China as a representative of a city experiencing rapid urbanization. We build up a multisource database (forest inventory, digital elevation models, population, and remote sensing imagery) on a uniform coordinate system to support research into the interactions that influence the STUFC. Landsat-5/8 Thermal Mapper images and meteorological data were used to retrieve the temporal and spatial distributions of land surface temperature. Ground observations, which included the forest management planning inventory and population density data, provided the factors that determine the STUFC spatial distribution on an urban scale. The use of a spatial statistical model (GeogDetector model) reveals the interaction mechanisms of STUFC. Although different environmental factors exert different influences on STUFC, in two periods with different hot spots and cold spots, the patch area and dominant tree species proved to be the main factors contributing to STUFC. The interaction between multiple environmental factors increased the STUFC, both linearly and nonlinearly. Strong interactions tended to occur between elevation and dominant species and were prevalent in either hot or cold spots in different years. In conclusion, the combining of multidisciplinary methods (e.g., remote sensing images, ground observations, and spatial statistical models) helps reveal the mechanism of STUFC on an urban scale.

Managing Multiple Catchment Demands for Sustainable Water Use and Ecosystem Service Provision

Ensuring water, food and energy security for a growing world population represents a 21st century catchment management challenge. Failure to recognise the complexity of interactions across ecosystem service provision can risk the loss of other key environmental and socioeconomic benefits from the natural capital of catchment systems. In particular, the ability of soil and water to meet human needs is undermined by uncertainties around climate change effects, ecosystem service interactions and conflicting stakeholder interests across catchments. This critical review draws from an extensive literature to discuss the benefits and challenges of utilising an ecosystem service approach for integrated catchment management (ICM). State-of-the-art research on ecosystem service assessment, mapping and participatory approaches is evaluated and a roadmap of the key short- and longer-term research needs for maximising landscape-scale ecosystem service provision from catchments is proposed.

Pacific connections for health, ecosystems and society: new approaches to the land-water-health nexus

Renewed effort to understand the social-ecological context of health is drawing attention to the dynamics of land and water resources and their combined influence on the determinants of health. A new area of research, education and policy is emerging that focuses on the land-water-health nexus: this orientation is applicable from small wetlands through to large-scale watersheds or river basins, and draws attention to the benefits of combined land and water governance, as well as the interrelated implications for health, ecological and societal concerns. Informed by research precedents, imperatives and collaborations emerging in Canada and parts of Oceania, this review profiles three integrative, applied approaches that are bringing attention to the importance the land-water-health nexus within the Pacific Basin: wetlands and watersheds as intersectoral settings to address land-water-health dynamics; tools to integrate health, ecological and societal dynamics at the land-water-health nexus; and indigenous leadership that is linking health and well-being with land and water governance. Emphasis is given to key characteristics of a new generation of inquiry and action at the land-water-health nexus, as well as capacity-building, practice and policy opportunities to address converging environmental, social and health objectives linked to the management and governance of land and water resources.

Challenges and Opportunities of Integrating Human Health into the Environmental Assessment Process: The Canadian Experience Contextualised to International Efforts

A scoping review of the literature was conducted to identify the most pressing issues pertaining to the application of Health Impact Assessment (HIA) and the integration of health concerns into the Environmental Assessment (EA) process in Canada and internationally. The issues identified include the need for government intervention, gaps in methodology and tools, limitations of capacity and expertise, poor intersectoral, disciplinary and public collaboration/participation, challenges of data quantification and analytic complexity, and the need for process efficiency. The issues presented were also contextualised to the status quo practice of EA in Canada and the Canadian Environmental Assessment Act (CEAA 2012). Recommendations were proposed as a starting point for improved integration. First, a commitment by the actors involved to the protection of human health — aligned with the core mandate of the CEAA. Second, the achievement of intersectoral, disciplinary and public collaboration, led by government, ideally the health sector. The case is made for a new era of Canadian leadership and innovation at the interface of health and EA.

Towards adaptive management of the natural capital: Disentangling trade-offs among marine activities and seagrass meadows

This paper investigates the ecological, social and institutional dimensions of the synergies and trade-offs between seagrasses and human activities operating in the Natura 2000 protected site of San Simón Bay (Galicia, NW Spain). By means of a multidisciplinary approach that brings together the development of a biological inventory combined with participatory mapping processes we get key spatial and contextual understanding regarding how, where and why marine users interact with seagrasses and how seagrasses are considered in policy making. The results highlight the fisheries' reliance on seagrass meadows and the controversial links with shellfisheries. The study also reveals unresolved conflicts among those management plans that promote the protection of natural values and those responsible for the exploitation of marine resources. We conclude that the adoption of pre-planning bottom-up participatory processes is crucial for the design of realistic strategies where both seagrasses and human activities were considered as a couple system.
