International benchmarking: Policy responses to biodiversity and climate change in OECD countries

Responding to global environmental issues like biodiversity loss and climate change challenge national governments and intergovernmental bodies. A conventional response has been to set targets. Yet to achieve targets, governments must implement effective policies. Indicators that track policy implementation could provide information on individual country progress towards targets and for international benchmarking. We take up a recommendation from Convention on Biological Diversity mandated experts to develop a policy indicator(s) for biodiversity. This expert group identified four indicator attributes: identification, establishment, strengthening and assessment. We review biodiversity (and climate change) policies implemented in the period 1952–2012 in 54 nations using an Organisation for Economic Co-operation and Development (OECD) database. We find: the number of countries implementing biodiversity policies increased steadily until the end of the 2000s (identification); evidence of continuous innovation in the types of policy instruments implemented (establishment); and evidence of policy revision and shifts in jurisdiction (strengthening). To overcome a lack of data to evaluate policy effectiveness (assessment) we suggest improvements in data collection and the possibility to combine the OECD database with other databases

Building capacities for transformative change towards sustainability: Imagination in Intergovernmental Science-Policy Scenario Processes

Scenario development has been recognized as a potential method to explore future change and stimulate a reflective process that can contribute to more informed decision-making. The assessment process under IPBES (the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) has however shown that the current predominantly biophysical and economic models and scenario processes for exploring the future of biodiversity, ecosystem services and their contributions to human wellbeing are insufficient to capture the complexity and context-specific nature of the problems facing these sectors. Several important challenges have been identified that require a more in-depth analysis of where more imaginative scenario efforts can be undertaken to address this gap. In this paper, we identify six key characteristics necessary for scenario processes: adaptability across diverse contexts, inclusion of diverse knowledge and value systems, legitimate stakeholder engagement that foregrounds the role of power and politics, an ability to grapple with uncertainty, individual and collective thinking mechanisms and relevance to policy making. We compared four cases of imaginative, arts-based scenario processes that each offer aspects of meeting these criteria. These approaches emphasise the importance of engaging the imagination of those involved in a process and harnessing it as a tool for identifying and conceptualising more transformative future trajectories. Drawing on the existing literature, we argue that there is value in fostering more inclusive and creative participatory processes that acknowledge the importance of understanding multiple value systems and relationships in order to reimagine a more inclusive and just future. Based on this, we reflect on future research to understand the transformative role that imagination can play in altering and enhancing knowledge-making for global assessments, including IPBES. We conclude that creative scenario co-development processes that promote imagination and create an opening for more empathetic responses should be considered as complementary tools within the suite of methodologies used for future IPBES scenario development

Interactions between climate change and land use change on biodiversity: attribution problems, risks, and opportunities

Global change drivers are known to interact in their effects on biodiversity, but much research to date ignores this complexity. As a consequence, there are problems in the attribution of biodiversity change to different drivers and, therefore, our ability to manage habitats and landscapes appropriately. Few studies explicitly acknowledge and account for interactive (i.e., nonadditive) effects of land use and climate change on biodiversity. One reason is that the mechanisms by which drivers interact are poorly understood. We evaluate such mechanisms, including interactions between demographic parameters, evolutionary trade-offs and synergies and threshold effects of population size and patch occupancy on population persistence. Other reasons for the lack of appropriate research are limited data availability and analytical issues in addressing interaction effects. We highlight the influence that attribution errors can have on biodiversity projections and discuss experimental designs and analytical tools suited to this challenge. Finally, we summarize the risks and opportunities provided by the existence of interaction effects. Risks include ineffective conservation management; but opportunities also arise, whereby the negative impacts of climate change on biodiversity can be reduced through appropriate land management as an adaptation measure. We hope that increasing the understanding of key mechanisms underlying interaction effects and discussing appropriate experimental and analytical designs for attribution will help researchers, policy makers, and conservation practitioners to better minimize risks and exploit opportunities provided by land use-climate change interactions

Patriotic values for public goods: transnational trade-offs for biodiversity and ecosystem services?

The natural environment is central to human well-being through its role in ecosystem service (ES) provision. Managing ES often requires coordination across international borders. Although this may deliver greater conservation gains than countries acting alone, we do not know whether the public supports such an international approach. Using the same questionnaire in three countries, we quantified public preferences for ES in home countries and across international borders. In all three countries, the people were generally willing to pay for ES. However, our results show that there is a limit to the extent that environmental goods can be considered global. ES with a use element (habitat conservation, landscape preservation) attracted a patriotic premium, such that the people were willing to pay significantly more for locally delivered services. Supranational management of ES needs to be balanced against the preferences that people have for services delivered in their home countries

Mapping natural capital: optimising the use of national scale datasets

Understanding the spatial distribution of specific environmental variables and the interdependencies of these variables is crucial for managing the environment in a sustainable way. Here we discuss two methods of mapping – a Geographical Information System classification-based approach and a statistical model-based approach. If detailed, spatially comprehensive covariate datasets exist to complement the ecological-response data, then using a statistical model-based analysis provides the potential for greater understanding of underlying relationships, as well as the uncertainty in the spatial predictions. Further, the model-based approach facilitates scenario testing. Although similar methods are already adopted in species distribution modeling, the flexibility of the model framework used is rarely exploited to go beyond modeling occupancy or suitability for a single species, into modeling complex derived metrics such as community composition and indicators of natural capital. As an example, we assess the potential benefits of the statistical model-based approach to mapping natural capital through the use of two national survey datasets; The Centre for Ecology and Hydrology (CEH) Land Cover Map (LCM) and the British Geological Survey’s (BGS) Parent Material Model (PMM), to predict national soil microbial community distributions based on data from a sample of > 1000 soils covering Great Britain. The results are mapped and compared against a more traditional, land classification-based approach. The comparison shows that, although the maps look broadly similar, the model-based approach provides better overall spatial prediction, and the contribution of individual model terms (along with their uncertainty) are far easier to understand and interpret, whilst also facilitating any scenario testing. We therefore both recommend the use of spatial statistical modelling techniques to map natural capital and anticipate that they will become more prominent over the forthcoming years

Tropical grassy biomes: linking ecology, human use and conservation

Tropical grassy biomes (TGBs) are changing rapidly the world over through a coalescence of high rates of land-use change, global change and altered disturbance regimes that maintain the ecosystem structure and function of these biomes. Our theme issue brings together the latest research examining the characterization, complex ecology, drivers of change, and human use and ecosystem services of TGBs. Recent advances in ecology and evolution have facilitated a new perspective on these biomes. However, there continues to be controversies over their classification and state dynamics that demonstrate critical data and knowledge gaps in our quantitative understanding of these geographically dispersed regions. We highlight an urgent need to improve ecological understanding in order to effectively predict the sensitivity and resilience of TGBs under future scenarios of global change. With human reliance on TGBs increasing and their propensity for change, ecological and evolutionary understanding of these biomes is central to the dual goals of sustaining their ecological integrity and the diverse services these landscapes provide to millions of people. This article is part of the themed issue ‘Tropical grassy biomes: linking ecology, human use and conservation’

Reconciling place attachment with catchment-based flood risk management:What can we learn from film?

A catchment-based approach to flood risk management (FRM) is gaining prominence in the United Kingdom. It is undertaken with wider awareness of multiple stakeholders, as part of a catchment scale understanding, and, as with other approaches, can visually re-shape place. Land cover and land management change at this scale also has the potential to reconfigure landscape values and place attachment. Researchers have used qualitative, quantitative, and mapping approaches to understand place attachment. Here we explore secondary data, specifically, we transcribe and code the stories of five Mytholmroyd, West Yorkshire residents from the short film, Calder about the December 26, 2015 floods. We find place attachment, identity, and social capital are interconnected and feature strongly in the mitigation and prevention phase, post-disaster. Our findings suggest better understanding of place attachment can support a more catchment scale approach to FRM policy and practice

Participatory mapping with indigenous communities for conservation: challenges and lessons from Suriname

The indigenous peoples of Southern Suriname depend on landscape services provided by intact, functioning ecosystems, but their use and reliance on natural landscapes is not well understood. In 2011, Conservation International Suriname (CIS) engaged in a participatory GIS (PGIS) mapping project to identify ecosystem services with the Trio and Wayana indigenous peoples living in five villages in Southern Suriname. The PGIS project involved a highly remote and inaccessible region, multiple indigenous peoples, villages with different perceptions and experiences with outsiders, and a multitude of regional development pressures. We describe the PGIS project from inception to mapping to communication of the results to the participants with a particular focus on the challenges and lessons learned from PGIS project implementation. Key challenges included decoupling the PGIS process from explicit CIS conservation objectives, engaging reluctant villages in the project, and managing participant expectations about project outcomes. Lessons learned from the challenges included the need to first build trust through effective communication, selecting initial project locations with the greatest likelihood of success, and to manage expectations by disclosing project limitations with the indigenous communities and external parties

Global Trends in the Status of Bird and Mammal Pollinators

Biodiversity is declining, with direct and indirect effects on ecosystem func-tions and services that are poorly quantified. Here, we develop the first globalassessment of trends in pollinators, focusing on pollinating birds and mam-mals. A Red List Index for these species shows that, overall, pollinating birdand mammal species are deteriorating in status, with more species movingtoward extinction than away from it. On average, 2.5 species per year havemoved one Red List category toward extinction in recent decades, represent-ing a substantial increase in the extinction risk across this set of species. Thismay be impacting the delivery of benefits that these species provide to people.We recommend that the index be expanded to include taxonomic groups thatcontribute more significantly to pollination, such as bees, wasps, and butter-flies, thereby giving a more complete picture of the state of pollinating speciesworldwide
