Whose voices count in biodiversity conservation? Ecological democracy in biodiversity offsetting,REDD+, and rewilding

ABSTRACT

Ecological democracy seeks environmentally sustainable ends through broad, active democratic participation. What happens when laws fostering participation in environmental decision-making and biodiversity preservation lead to differing results? What is best for biodiversity may not be what for local citizens believe is best. I examine conflicts and congruencies in the context of Biodiversity Offsetting, REDD+ (Reducing Emissions from Deforestation and forest Degradation), and the Rewilding movement. I ask questions that are legal (Who has what legal rights to speak for or against programs that enhance biodiversity?), epistemological (Whose expertise and knowledge matters when scientists and non-scientists don't agree?), axiological (Are some values objectively better, and why?), and normative (Whose opinions about biodiversity should count?). Many people have the right to participate in an ecological democracy: But when protecting biodiversity, who does and should have the right to be heard? I problematize the role that ‘local’ actors play in decision-making and describe the variegated role that experts – particularly biologists – play in ecological democracy when biodiversity preservation matters. To determine whose values and voices should be prioritized, I describe ‘deep equity,’ an axiological and normative groundwork for determining when biodiversity-promoting policies may be preferable even if affected citizens don't agree.     

Between environmental and ecological democracy: theory and practice at the democracy-environment nexus

ABSTRACT

Concepts of ecological and environmental democracy seek to reconcile two normative ideals: ensuring environmental sustainability while safeguarding democracy. These ideals are frequently conceived as being in conflict, as democracy is perceived as too slow and cumbersome to deliver the urgent large-scale collective action needed to tackle environmental problems. Theories addressing the democracy-environment nexus can be situated on a spectrum from theories of ecological democracy that are more critical of existing liberal democratic institutions to theories of environmental democracy that call for reforming rather than radically transforming or dismantling those institutions. This article reviews theoretical and empirical scholarship on the democracy-environment nexus. We find continued theoretical and empirical diversity in the field, as well as vibrant debates on democratising global environmental politics, local material practices, and non-human representation. We argue for stronger dialogue between environmental political theory and empirical, policy-oriented research on democracy and sustainability, as well as further exploration of complementarities between ecological and environmental democracy. We identify four main areas of challenge and opportunity for theory and practice: public participation and populism; technocracy and expertise; governance across scales; and ecological rights and limits.

The use of terrestrial ecoregions as a regional-scale screen for selecting representative reference sites for water quality monitoring

A process has been developed to select watersheds that are representative of terrestrial ecoregions and that are relatively undisturbed by human activity. Using an existing land classification system at two hierarchical levels of resolution, representative subsets (ecodistricts) of large-scale ecoregions were selected, on the basis of their physiographic, biological, and climatological attributes, to represent the ecoregions. This was achieved using a frequency distribution analysis of existing attribute data and choosing the ecodistrict most closely resembling the most common set of conditions for that ecoregion. Within each ecodistrict, river basins were selected through a best-judgement evaluation of land use, coupled with an assessment of the size and location of each river basin, in order to meet the condition of minimal human impact. Preliminary assessment of water quality data collected from six watersheds selected in this way suggests that the process is effective in targeting regional scale river basins exhibiting the desired characteristics.     

Strategies to overcome barriers to the development of sustainable agriculture in Canada: The role of agribusiness

Strategies to involve agribusiness in the development of sustainable agricultural systems have been limited by the lack of a comprehensive conceptual framework for identifying the most critical supportive policies, programs and regulations. In this paper, we propose an efficiency/substitution/redesign framework to categorize strategies for modifying agribusiness practices. This framework is then used to identify a diverse range of short, medium, and long-term strategies to be pursued by governments, community groups, academics and agribusiness to support the transition. Strategies discussed include corporate greening, ethical investment, changing the legal status of the corporaton, new business forms and the development of ecological economics.     

A national critical loads framework for atmospheric deposition effects assessment: II. Defining assessment end points,indicators, and functional subregions

The United States Environmental Protection Agency, with support from the US Department of Energy and the National Oceanographic and Atmospheric Administration, has been evaluating the feasibility of an effects-based (critical loads) approach to atmospheric pollutant regulation and abatement. The rationale used to develop three of the six steps in a flexible assessment framework (Strickland and others, 1992) is presented along with a discussion of a variety of implementation approaches and their ramifications. The rationale proposes that it is necessary to provide an explicit statement of the condition of the resource that is considered valuable (assessment end point) because: (1) individual ecosystem components may be more or less sensitive to deposition, (2) it is necessary to select indicators of ecosystem condition that can be objectively measured and that reflect changes in the quality of the assessment end point, and (3) acceptable status (i.e., value of indicator and quality of assessment end point at critical load) must be defined. The rationale also stresses the importance of defining the assessment regions and subregions to improve the analysis and understanding of the indicator response to deposition. Subregional definition can be based on a variety of criteria, including informed judgment or quantitative procedures. It also depends on the geographic scale at which exposure and effects models are accurate and on data availability, resolution, and quality.

论中国城市灾害科学的现状研究及新构想

城市是一个国家和地区的经济、政治、文化中心,是一个综合了社会、心理、地理、工程、功能、生态等学科在内的复杂系统工程,是人双重属性(自然与社会)的一个载体。面对现状及21世纪我国城市建设的挑战,本文认为不仅应研究优美的景观、平衡的生态、高效的功能及无障碍特性,还必须提高一个现代化城市抗御灾害的综合能力。“国际减灾十年”全球统一行动应同环境治理一样,成为衡量城市现代化的标志。     

Shortfalls in minerals investments

The international minerals industry continues to have a substantial investment shortfall. The widening exploration and mineral development gaps, not only in the lesser developed countries but also in the developed nations, are sowing the seeds for future mineral supply disruptions and conflicts. Mutuality of interests demands concerted initiatives, individual as well as collective, to reverse the investment trends established by international mineral finance and the multinational corporations in order to pave the way for secure mineral supplies in the future at acceptable prices.
