Bottom-up perspectives on nature conservation systems: The differences between regional and local administrations

Many proposals to improve biodiversity governance target the stage of policy formulation. In this paper we highlight the importance of the subsequent policy realization stage, which is mostly carried out by sub-national administrative levels. We explore the differences in the opinions of practitioners representing regional and local public institutions in conservation policy design and implementation. The research was conducted through surveying a representative sample of local and regional practitioners within Małopolska, Poland. The results illustrate a cross-level mismatch between the regional and local practitioners. That is, practitioners operating at different administrative levels have significantly different opinions on nature conservation system performance, system effectiveness, the distribution of power among actors, and on the allocation of costs and benefits stemming from nature conservation. Local level representatives are generally more pleased with overall nature conservation performance and its outcomes, while regional level representatives are more skeptical, especially toward local level performance and the overall effectiveness of nature conservation. Also, local level respondents are more critical, while regional practitioners hold more positive images of the procedures involved during policy implementation. We highlight the practical implications of this kind of research, and the importance of quantitative data in evaluating the overall performance of conservation policy.     

An evaluation of ecological impact assessment procedural effectiveness over time

Environmental Impact Assessment (EIA) is an important tool to help decision-makers balance the environmental impacts of a proposed built development with its potential economic benefits. Used in most countries across the globe, EIA commonly includes an ecological component (Ecological Impact Assessment, or EcIA). However, despite considerable changes in relevant legislation, policy and guidance, there has been no recent review of UK EcIA chapter content, with the latest review having been published in 2000.This study attempts to determine the procedural effectiveness of EcIA chapters over time by comparing a new review of 112 English EcIA chapters from 2000 onwards with earlier reviews. This was achieved through the novel use of inferential statistics, an approach previously lacking in the EIA and EcIA review literature.The limitations and advantages of the use of quantitative methods are discussed. In general, there has been an improvement in the information content of EcIA chapters over time, for example in the percentage of EcIA chapters stating the size of the development and estimating the likely effectiveness of proposed mitigation measures. However, the earlier reviews highlighted such severe information deficiencies that the progress seen in the post-2000 EcIA chapter review still leaves considerable scope for improvement.Changes in the EU’s EIA Directive in force since May 2014 (and to be transposed into Member State legislation by May 2017) have the potential to encourage the use of inferential statistics in EIA and EcIA review: the requirement for Member States to provide central access to EIA information should enable representative samples to be analysed.     

Reporting marine climate change impacts: Lessons from the science-policy interface

Climate change science can trace its origins back to the early 19th Century although interest really took off in the 1980s, when public interest and research activity proliferated as the potential negative effects of global warming became clear. The impacts of climate change on the marine environment was receiving little attention at this time, but in recent years has started to “catch up” both in terms of research activity and public and policy interest. In the UK, the Marine Climate Change Impacts Partnership (MCCIP) has played a key role in transferring the emerging evidence base on marine climate change impacts to decision makers through the development of climate change report cards. Since publishing its first card back in 2006, the MCCIP cards have become established as the principal source of marine climate change impacts evidence for policy makers in the UK, and similar approaches have been adopted elsewhere. Here we broadly describe how the climate change evidence base has evolved over time, with a focus on the marine evidence base, and the approach adopted in the UK by MCCIP to rapidly transfer this evidence to end users. The SIIRMS model developed by MCCIP to ensure integrity and independence in the scientific translation process is explored, along with wider lessons learnt along the way (e.g. about communicating uncertainty) and the impact MCCIP has had on informing decision making.     

Best practices for corporate commitment to biodiversity: An organizing framework from GRI reports

Corporate operations can have significant impacts on biodiversity. Nevertheless, the literature has overlooked the analysis of the organizational practices underlying corporate commitment to biodiversity. The objective of this article is to contribute to this under-researched issue by shedding light on the best practices of biodiversity conservation of companies whose operations pose high risks to biodiversity. For this purpose, we carried out a systematic analysis of the sustainability practices reported by 163 mining and forestry companies whose operations pose high risks to biodiversity. The article proposes an organizing framework describing the main approaches and practices for corporate biodiversity management. The contributions and implications for managers, policy makers and other stakeholders are discussed.     

The participation of experts and knowledges in the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES)

This paper examines the participation opportunities and role of nominated experts from the Eastern European region in the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). The governance of international knowledge-making spaces and events occurs through standardised institutional rules and expectations that affect experts as well as define accepted forms of knowledge. Within IPBES, experts may participate through United Nations Regional Groupings, which are regions that have complex geopolitical legacies and features. Between regions, experts have variable financial, networking and institutional capacities that in turn affect the operations and outputs of their contributions to science-policy interfaces. For IPBES, regional and localised environmental assessments and ecosystem services valuations require existing place-specific knowledge that may not be ‘available’, as well as understandings that are frequently in conflict with the standardised, homogenising practices of international environmental knowledge-making.     

Do biodiversity indices behave as expected from traits of constituent species in simulated scenarios?

It is believed that diversity of plant communities has a positive effect on their productivity. The benefits of diversity are described by “biodiversity indices”, comparing yield of mixtures with yields of monocultures of constituent species. These indices are supposed to capture also the main mechanisms leading to increased yield. We have constructed a spatially explicit individual based model, simulating even-aged stand development, and compared the behaviour of selected biodiversity indices (overyielding, selectivity and complementarity) with expectations based on life history traits of constituent species. The results are based on comparisons of two species mixtures with corresponding monocultures. We designed three scenarios of changes in the two species life history differentiation, and compared the behaviour of the indices with expectation based on it. In the first scenario, selectivity was driven by increasing size inequality of the two species, mostly in accordance with expectations. The second scenario presents increasing shade tolerance of the smaller species that increased complementarity, again mostly as expected. In the last scenario, shortening of length of stress tolerance of the weaker species surprisingly increased values of the biodiversity indices. For each setting, we varied sowing density and spatial pattern of the constituent species. The behaviour of the indices was influenced by both factors, but the effect of density was more pronounced. In particular, at high sowing densities, the most important interactions happened in the very early stages of mixture development, and the behaviour of the indices was often counter-intuitive.     

Sustaining Jamaica's forests: The protected areas resource conservation project

This study examines Jamaica's attempt to protect a tropical forest reserve. The biophysical setting, and the types and magnitude of forest development pressures are reviewed. Next, Jamaica's approach to developing new land-use strategies and compatible environmental protection and economic development programs are examined. Finally, the practical and theoretical implications by which institutions can be designed to encourage planning for sustainable development are reviewed. The implications suggest how to provide an appropriate mix of cooperation and market competition, by which people acting in their own interests accomplish socially equitable economic development, while protecting the environment for the benefit of future generations. The experience illustrates that effective long-term protection of natural areas requires the building of local relationships and support, the development of local economic activities supportive of conservation, the defining of clear boundaries, and significant monitoring and enforcement. Long-term protection of the Blue and John Crow mountains, and other important natural areas of Jamaica, will also require the development of a workable and enforceable system of land-use planning for the island, and adjustments to the economic incentive structure so that sustainable, nonextractive uses of natural capital are placed on equal footing with other economic uses (e.g., coffee production).     

Respective influence of habitat conditions and management regimes on prealpine calcareous grasslands

The calcareous grasslands of the south-western French Alps have been poorly studied, although they provide suitable habitat for rare plant species and communities. The separate and combined effects on calcareous grassland communities of habitat conditions (lithology, soil moisture) and management regimes (grazing intensity, cutting regime) were studied using constrained ordination techniques (canonical correspondence analysis with variance partitioning). Among the explanatory variables considered, the most important factor determining floristic composition was lithology, which explained 11.9% of floristic variability, followed by grazing intensity (6.0%). Additive effects of management and lithology explained 23.9% of floristic variability. Species niche amplitude was measured by conditional variances of samples along main ordination axes, in order to define adequate conservation management for the rarest short-lived species with narrow niche breadth on both habitat and management gradients.     

Tree Structure and Diversity in Human-Impacted Littoral Forests, Madagascar

This research surveyed human-impacted littoral forests in southeastern Madagascar to determine (i) how forest structural features, indicative of human impact, are related to total, utilitarian, and endemic tree diversity; (ii) the distribution, abundance, and demographics of tree species groups (i.e., total, useful, endemic) across the landscape; and (iii) the amount of basal area available per human use category. We also use these data to consider issues of sustainable use and how human impact may influence littoral forest tree community composition across the landscape. Within 22 transects of 400 m² each, we recorded a total of 135 tree species and 2155 individuals. Seventy-nine species (58%) were utilitarian and 56 (42%) were nonutilitarian species. Of the 2155 individuals, 1827 (84%) trees were utilitarian species. We recorded 23 endemic species (17% of the total species) and 17 (74%) of these were utilitarian species. Basal area was significantly correlated with Shannon Weiner Index values for total (r = 0.64, P < 0.01), utilitarian (r = 0.58, P < 0.01), and endemic tree diversity (r = 0.85, P < 0.01). Basal area was significantly correlated with the Simpson’s index values for the endemic species (r = 0.74, P < 0.01). These correlations suggest that endemic tree species, of high global conservation value, may be the species group most influenced by changes in forest structure. Utilitarian species constituted 84% of the total basal area. The use category contributing the highest amount of basal area to the landscape was firewood. The results presented herein demonstrate that the landscape of southeastern Madagascar, commonly perceived as degraded, retains high value for both global conservation purposes and for local livelihoods. Thus, valuable opportunities may exist for developing conservation incentives that leverage both global and local conservation needs.     

On the value of endangered and other species

This paper describes two frameworks—utilitarian and Kantian—society uses to make decisions concerning environmental management and, in particular, species protection. The utilitarian framework emphasizes the consequences of choices for prior preferences. A perfectly competitive market, on this model, correctly values environmental resources. The Kantian approach identifies rules appropriate to recognized situations given the identity of the decision maker. It relies on democratic political processes and institutions to provide the means by which citizens determine the identity of their community—its moral character and aspirations—and match appropriate rules to recognized situations. This paper argues that markets do not fail in any general way in measuring the economic value of plants and animals. Market prices, in general, correctly represent the marginal or exchange value of species. If society legislates against extinction, this must be understood as an exercise in Kantian decision making in view of the moral value of species, not as an attempt to correct a market failure or to promote social welfare or utility.
