Global Metrics for Terrestrial Biodiversity
Biodiversity metrics are increasingly in demand for informing government, business, and civil society decisions. However, it is not always clear to end users how these metrics differ or for what purpose they are best suited. We seek to answer these questions using a database of 573 biodiversity-related metrics, indicators, indices, and layers, which address aspects of genetic diversity, species, and ecosystems. We provide examples of indicators and their uses within the stateâpressureâresponseâbenefits framework that is widely used in conservation science. Considering complementarity across this framework, we recommend a small number of metrics considered most pertinent for use in decision-making by governments and businesses. We conclude by highlighting five future directions: increasing the importance of national metrics, ensuring wider uptake of business metrics, agreeing on a minimum set of metrics for government and business use, automating metric calculation through use of technology, and generating sustainable funding for metric production
Transforming Biodiversity Data into Knowledge for Decision-making
Ensuring that we have the data and information necessary to make informed decisions is a core requirement in an era of increasing complexity and anthropogenic impact. With cumulative challenges such as the decline in biodiversity and accelerating climate change, the need for spatially-explicit and methodologically-consistent data that can be compiled to produce useful and reliable indicators of biological change and ecosystem health is growing.
Technological advancesâincluding satellite imageryâare beginning to make this a reality, yet uptake of biodiversity information standards and scaling of data to ensure its applicability at multiple levels of decision-making are still in progress. The complementary Essential Biodiversity Variables (EBVs) and Essential Ocean Variables (EOVs), combined with Darwin Core and other data and metadata standards, provide the underpinnings necessary to produce data that can inform indicators. However, perhaps the largest challenge in developing global, biological change indicators is achieving consistent and holistic coverage over time, with recognition of biodiversity data as global assets that are critical to tracking progress toward the UN Sustainable Development Goals and Targets set by the international community (see Jensen and Campbell (2019) for discussion).
Through this talk, I will describe some of the efforts towards producing and collating effective biodiversity indicators, such as those based on authoritative datasets like the World Database on Protected Areas (https://www.protectedplanet.net/), and work achieved through the Biodiversity Indicators Partnership (https://www.bipindicators.net/). I will also highlight some of the characteristics of effective indicators, and global biodiversity reporting and communication needs as we approach 2020 and beyond
Scenarios for coastal First Nations' fisheries under climate change : impacts, resilience and adaptation potential
Recent studies have demonstrated ways in which climate-related shifts in the distribution and relative abundance of marine species are expected to alter the dynamics and catch potential of global fisheries. While these studies focus on assessing impacts to commercial fisheries, few efforts have been made to quantitatively project impacts to small-scale fisheries that are economically, socially and culturally important to many coastal communities. This study uses a dynamic bioclimate envelope model to project scenarios of climate-related changes in the relative abundance, distribution and richness of 98 exploited marine fishes and invertebrates that are of commercial and cultural importance to First Nations in coastal British Columbia, Canada. Declines in relative abundance are projected for most of the sampled species (n = 84 to 95; xÌ
= -15.0% to -20.8%) under both the lower and upper scenarios of climate change, with poleward range shifts occurring at a mean rate of 2.9 and 4.5 kilometres decade-1 for fishes and 2.7 to 3.4 kilometres decade-1 for invertebrates within BCâs exclusive economic zone. While cumulative declines in catch potential are projected to occur coastwide (-4.5 to -10.7%), estimates suggest a strong positive correlation between relative catch potential and latitude, with First Nationsâ territories along the north and central coasts experiencing less severe declines than those to the south. Furthermore, a strong negative correlation is projected between latitude and the number of species exhibiting declining abundance. These trends are shown to be robust to alternative species distribution models, and highlight key management challenges that are likely to be encountered under climate change. Drawing from an interdisciplinary literature review of First Nationsâ traditional fisheries management strategies and historical responses to changes in the availability of aquatic resources, a scenario-based framework is applied to explore climate-resilient pathways for First Nationsâ fisheries given quantitative projections. Findings suggest that joint-management frameworks incorporating First Nationsâ traditional ecological knowledge could aid in offsetting impacts and developing site-specific mitigation and adaptation strategies. This interdisciplinary framework thereby facilitates proactive discussions of potential mitigation and adaptation strategies deriving from local fishersâ knowledge that could be used to respond to a range of climate change scenarios.Science, Faculty ofResources, Environment and Sustainability (IRES), Institute forGraduat
Observed and projected impacts of climate change on marine fisheries, aquaculture, coastal tourism, and human health: an update
The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) states that climate change and ocean acidification are altering the oceans at a rate that is unprecedented compared with the recent past, leading to multifaceted impacts on marine ecosystems, associated goods and services, and human societies. AR5 underlined key uncertainties that remain regarding how synergistic changes in the ocean are likely to affect human systems, and how humans are likely to respond to these events. As climate change research has accelerated rapidly following AR5, an updated synthesis of available knowledge is necessary to identify emerging evidence, and to thereby better inform policy discussions. This paper reviews the literature to capture corroborating, conflicting, and novel findings published following the cut-off date for contribution to AR5. Specifically, we highlight key scientific developments on the impacts of climate-induced changes in the ocean on key socioeconomic sectors, including fisheries, aquaculture and tourism. New evidence continues to support a climate-induced redistribution of benefits and losses at multiple scales and across coastal and marine socio-ecological systems, partly resulting from species and ecosystem range shifts and changes in primary productivity. New efforts have been made to characterize and value ecosystem services in the context of climate change, with specific relevance to ecosystem-based adaptation. Recent studies have also explored synergistic interactions between climatic drivers, and have found strong variability between impacts on species at different life stages. Although climate change may improve conditions for some types of freshwater aquaculture, potentially providing alternative opportunities to adapt to impacts on wild capture fisheries, ocean acidification poses a risk to shellfish fisheries and aquaculture. The risk of increased prevalence of disease under warmer temperatures is uncertain, and may detrimentally affect human health. Climate change may also induce changes in tourism flows, leading to substantial geospatial shifts in economic costs and benefits associated with tourism revenue and coastal infrastructure protection and repairs. While promising, ecosystem-based coastal adaptation approaches are still emerging, and require an improved understanding of key ecosystem services and values for coastal communities in order to assess risk, aid coastal development planning, and build decision support systems
Is citizen science an open science in the case of biodiversity observations?
International audience1. There is a high demand for biodiversity observation data to inform conservation and environmental policy, and citizen scientists generate the vast majority of terrestrial biodiversity observations. As this work is voluntary, many people assume that these data are openly available for use in conservation and scientific research.2. Here, the openness of biodiversity observation data that are contributed to the Global Biodiversity Information Facility is examined by the data provider. Contrary to what many people assume, data sets from volunteers are among the most restrictive in how they can be used.3. Policy implications. The assumption that voluntary data collection leads to data sharing does not recognize the wishes and motivations of those who collect data, nor does it respect the crucial contributions of these data to longâterm monitoring of biodiversity trends. To improve data openness, citizen scientists should be recognized in ways that correspond with their motivations. Furthermore, organizations that manage these data should make their data sharing policies open and explicit

A Global Estimate of Seafood Consumption by Coastal Indigenous Peoples
<div><p>Coastal Indigenous peoples rely on ocean resources and are highly vulnerable to ecosystem and economic change. Their challenges have been observed and recognized at local and regional scales, yet there are no global-scale analyses to inform international policies. We compile available data for over 1,900 coastal Indigenous communities around the world representing 27 million people across 87 countries. Based on available data at local and regional levels, we estimate a total global yearly seafood consumption of 2.1 million (1.5 millionâ2.8 million) metric tonnes by coastal Indigenous peoples, equal to around 2% of global yearly commercial fisheries catch. Results reflect the crucial role of seafood for these communities; on average, consumption per capita is 15 times higher than non-Indigenous country populations. These findings contribute to an urgently needed sense of scale to coastal Indigenous issues, and will hopefully prompt increased recognition and directed research regarding the marine knowledge and resource needs of Indigenous peoples. Marine resources are crucial to the continued existence of coastal Indigenous peoples, and their needs must be explicitly incorporated into management policies.</p></div
