Establishing IUCN Red List Criteria for Threatened Ecosystems

The potential for conservation of individual species has been greatly advanced by the International Union for Conservation of Nature\u27s (IUCN) development of objective, repeatable, and transparent criteria for assessing extinction risk that explicitly separate risk assessment from priority setting. At the IV World Conservation Congress in 2008, the process began to develop and implement comparable global standards for ecosystems. A working group established by the IUCN has begun formulating a system of quantitative categories and criteria, analogous to those used for species, for assigning levels of threat to ecosystems at local, regional, and global levels. A final system will require definitions of ecosystems; quantification of ecosystem status; identification of the stages of degradation and loss of ecosystems; proxy measures of risk (criteria); classification thresholds for these criteria; and standardized methods for performing assessments. The system will need to reflect the degree and rate of change in an ecosystem\u27s extent, composition, structure, and function, and have its conceptual roots in ecological theory and empirical research. On the basis of these requirements and the hypothesis that ecosystem risk is a function of the risk of its component species, we propose a set of four criteria: recent declines in distribution or ecological function, historical total loss in distribution or ecological function, small distribution combined with decline, or very small distribution. Most work has focused on terrestrial ecosystems, but comparable thresholds and criteria for freshwater and marine ecosystems are also needed. These are the first steps in an international consultation process that will lead to a unified proposal to be presented at the next World Conservation Congress in 2012

Food consumption trends and drivers

A picture of food consumption (availability) trends and projections to 2050, both globally and for different regions of the world, along with the drivers largely responsible for these observed consumption trends are the subject of this review. Throughout the world, major shifts in dietary patterns are occurring, even in the consumption of basic staples towards more diversified diets. Accompanying these changes in food consumption at a global and regional level have been considerable health consequences. Populations in those countries undergoing rapid transition are experiencing nutritional transition. The diverse nature of this transition may be the result of differences in socio-demographic factors and other consumer characteristics. Among other factors including urbanization and food industry marketing, the policies of trade liberalization over the past two decades have implications for health by virtue of being a factor in facilitating the ‘nutrition transition’ that is associated with rising rates of obesity and chronic diseases such as cardiovascular disease and cancer. Future food policies must consider both agricultural and health sectors, thereby enabling the development of coherent and sustainable policies that will ultimately benefit agriculture, human health and the environment

The challenges of long-term invasive mammal management: lessons from the UK

We consider the motivations, strategies, and costs involved in invasive mammal management undertaken in the UK. Widespread established invasive mammals require long‐term management to limit damage or spread, but ongoing management is costly and complex. Long‐term management is most effective where it is applied at a landscape scale, but this requires overarching co‐ordination between multiple stakeholders. Five challenges for successful long‐term management of invasive mammal species are identified as follows: defining landscape‐scale strategies, management co‐ordination, stakeholder and community engagement, sustainable funding, and evidence requirements. We make recommendations on the supportive infrastructure needed for effective landscape‐scale management of invasive mammals to fulfil long‐term conservation aims, as follows. 1. There is a need for evidence‐based Invasive Species Action Plans to provide strategy for the long‐term ongoing management of prioritised species at appropriate scales. 2. Where possible, multispecies approaches to invasive species management should be adopted. 3. Trusted leadership should be identified to take ownership of Action Plans and provide an overarching co‐ordination to bring individuals, organisations, and funders together. 4. Support for a centralised hub for training, data, and knowledge flows will greatly improve scientific outcomes through a searchable evidence base, and via best practice and knowledge sharing

UK local councils reporting of biodiversity values: a stakeholder perspective

Purpose This study explores the use of narratives in biodiversity reports as a mechanism to raise the awareness of biodiversity’s importance. By classifying biodiversity narratives into 14 categories of biodiversity values this paper investigates whether the explanations for biodiversity conservation used by UK local councils are line with shallow, intermediate or deep philosophies. Design/methodology/approach This study used content analysis to examine the disclosures on biodiversity’s importance in the biodiversity action plans published by UK local councils. The narratives were first identified and then allocated into 14 categories of biodiversity value. Then, they were ascribed to either shallow (resource conservation, human welfare ecology and preservationism), intermediate (environmental stewardship and moral extensionism) or deep philosophies. Findings UK local councils explained biodiversity’s importance mainly in terms of its instrumental value, in line with shallow philosophies such as human welfare ecology and resource conservation. UK local councils sought to raise awareness of biodiversity’ importance by highlighting values that are important for the stakeholders that are able to contribute towards biodiversity conservation such as landowners, residents, visitors, business and industries. We also found that local councils’ biodiversity strategies were strongly influenced by 2010, the International Year of Biodiversity. Originality/value This paper is one of the few accounting studies that engages with the literature on environmental ethics to investigate biodiversity. In line with stakeholder theory, it indicates that explanations on biodiversity’s importance based on anthropocentric philosophies are considered more effective in informing those stakeholders whose behaviour needs to be changed to improve biodiversity conservation

Integrative policy development for healthier people and ecosystems : a European case analysis

There is growing evidence of the inter‐relationships between ecosystems and public health. This creates opportunities for the development of cross‐sectoral policies and interventions that provide dual benefits to public health and to the natural environment. These benefits are increasingly articulated in strategy documents at national and regional level, yet implementation of integrative policies on the ground remains limited and fragmented. Here, we use a workshop approach to identify some features of this evidence–implementation gap based on policy and practice within a number of western European countries. The driving forces behind some recent moves towards more integrative policy development and implementation show important differences between countries, reflecting the non‐linear and complex nature of the policy‐making process. We use these case studies to illustrate some of the key barriers to greater integrative policy development identified in the policy analysis literature. Specific barriers we identify include: institutional barriers; differing time perspectives in public health and ecosystem management; contrasting historical development of public health and natural environment disciplinary policy agendas; an incomplete evidence base relating investment in the natural environment to benefits for public health; a lack of appropriate outcome measures including benefit–cost trade‐offs; and finally a lack of integrative policy frameworks across the health and natural environment sectors. We also identify opportunities for greater policy integration and examples of good practice from different countries. However, we note there is no single mechanism that will deliver integrative policy for healthier people and ecosystems in all countries and situations. National governments, national public agencies, local governments, research institutions, and professional bodies all share a responsibility to identify and seize opportunities for influencing policy change, whether incremental or abrupt, to ensure that ecosystems and the health of society are managed so that the interests of future generations, as well as present generations, can be protected

Australian approaches for managing ‘country’ using Indigenous and non-Indigenous knowledge

This paper synthesises the lessons learnt and challenges encountered when applying Indigenous and non-Indigenous knowledge and methods in natural and cultural resource management (NCRM) in northern and central Australia. We primarily draw on the papers within this special issue of Ecological Management & Restoration, which originated largely from the Indigenous land management symposium at the 2010 Ecological Society of Australia conference. Many of the papers and therefore this article discuss practical experiences that offer insight for enhanced on-ground cross-cultural NCRM and can inform broader thinking and theoretical critiques. A wider literature is also drawn upon to substantiate the points and broaden the scope of the synthesis. Four key themes for consideration in collaborative cross-cultural NCRM are discussed. They are as follows: 1. The differences in environmental philosophy between Indigenous and non-Indigenous cultures which profoundly shape perceptions of environmental management; 2. Cross-cultural awareness of Indigenous and non-Indigenous knowledge and methods; 3. The mechanics of two-way approaches to ecological research and managing country (NCRM as perceived by Indigenous people) and 4. Operational challenges for Indigenous NCRM organisations. To conclude, we point out five broad principles for managing country using Indigenous and non-Indigenous knowledge: (i) Recognise the validity of both Indigenous and non-Indigenous environmental philosophies; (ii) Create more opportunities for improved cross-cultural understanding, respect and collaborations; (iii) Involve Indigenous people and their knowledge and interests at all stages of the Indigenous NCRM project or research (including planning, design, implementation, communication and evaluation); (iv) Ensure that time and continuity of effort and resources are available (to undertake participatory processes and for trust-building and innovation) and (v) Establish high-level political support through legal and policy frameworks to maintain continuity of government commitment to Indigenous NCRM

Terrestrial Reserve Networks Do Not Adequately Represent Aquatic Ecosystems

Las áreas protegidas son una piedra angular de la conservación y han sido diseñadas principalmente alrededor de atributos terrestres. Las especies y ecosistemas dulceacuícolas se encuentran en peligro, pero la efectividad de las áreas protegidas existentes para representar las características dulceacuícolas es poco conocida. Utilizando las aguas interiores de Michigan como un caso de prueba, cuantificamos la cobertura de cuatro atributos dulceacuícolas clave (humedales, zonas ribereñas, recarga de agua subterránea y especies raras) en las tierras conservadas y las comparamos con la representación de los atributos terrestres. Los humedales estaban incluidos en las áreas protegidas más a menudo que lo esperado por azar, pero las zonas ribereñas estuvieron insuficientemente representadas en todas las tierras protegidas (GAP1–3), particularmente en manantiales y ríos grandes. Sin embargo, las zonas ribereñas estuvieron bien representadas en las tierras con protección estricta (GAP 1–2) debido a la contribución del Programa Nacional de Ríos Silvestres y Escénicos. La representación de áreas de recarga de aguas subterráneas generalmente fue proporcional al área de la red de reservas dentro de cuencas hidrológicas, aunque un sitio importante de recarga asociado con algunos de los ríos más valiosos en Michigan estaba casi totalmente desprotegido. La representación de especies en áreas protegidas difirió significativamente entre las especies acuáticas obligadas, de humedales y terrestres, con una representación generalmente mayor para las especies terrestres y menor para las acuáticas. Nuestros resultados ilustran la necesidad de evaluar y atender la representación de los atributos dulceacuícolas dentro de las áreas protegidas y el valor de ampliar el análisis de brechas y otras evaluaciones de áreas protegidas para incluir los procesos ecosistémicos claves que son requisito para la conservación a largo plazo de especies y ecosistemas. Concluimos que las redes de áreas protegidas orientadas al medio terrestre proporcionan una red de seguridad débil para los atributos acuáticos, lo que significa que se requiere planeación y manejo complementario tanto para objetivos de conservación dulceacuícolas como terrestres.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/79138/1/COBI_1460_sm_AppendixS3.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/79138/2/COBI_1460_sm_AppendixS1.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/79138/3/j.1523-1739.2010.01460.x.pd

A transatlantic perspective on 20 emerging issues in biological engineering

Advances in biological engineering are likely to have substantial impacts on global society. To explore these potential impacts we ran a horizon scanning exercise to capture a range of perspectives on the opportunities and risks presented by biological engineering. We first identified 70 potential issues, and then used an iterative process to prioritise 20 issues that we considered to be emerging, to have potential global impact, and to be relatively unknown outside the field of biological engineering. The issues identified may be of interest to researchers, businesses and policy makers in sectors such as health, energy, agriculture and the environment

Ecosystem services of collectively managed urban gardens : exploring factors affecting synergies and trade-offs at the site level

Collective management of urban green space is being acknowledged and promoted. The need to understand productivity and potential trade-offs between co-occurring ecosystem services arising from collectively managed pockets of green space is pivotal to the design and promotion of both productive urban areas and effective stakeholder participation in their management. Quantitative assessments of ecosystem service production were obtained from detailed site surveys at ten examples of collectively managed urban gardens in Greater Manchester, UK. Correlation analyses demonstrated high levels of synergy between ecological (biodiversity) and social (learning and well-being) benefits related to such spaces. Trade-offs were highly mediated by site size and design, resulting in a tension between increasing site area and the co-management of ecosystem services. By highlighting synergies, trade-offs and the significance of site area, the results offer insight into the spatially sensitive nature of ecosystem services arising from multi-functional collectively managed urban gardens
