RESUMO

Globalization persists the tendency to alter numerous aspects of today's world including religion, transport, language, living styles, and international relations; however, its potential to influence quality of environment is the prime concern for trade and environmental policies guidelines (Audi and Ali 2018). In response to the growing interest for identifying the dynamic relationship between globalization and environmental performance, the present study seeks to investigate the critical link between globalization and ecological footprints in top 15 globalized countries between 1970 and 2016. Applying the novel methods of quantile-on-quantile regression (QQ) and Granger causality in quantiles, the findings examine the manners in which quantiles of globalization affect the quantiles of ecological footprints and vice versa. The empirical results suggest that globalization has a long-term positive effect on ecological footprint and vice versa in case of Belgium, the Netherlands, Sweden, Switzerland, Denmark, Norway, Canada, and Portugal. On the other hand, the estimated results indicate a negative effect between globalization and ecological footprint in the case of France, Germany, the UK, and Hungary. These results extend the recent findings on the globalization-environment nexus implying that the magnitude of relationship among both variables varies with countries demanding individual focus and cautions for postulating environmental and trade policies.

RESUMO

Research in applied ecology provides scientific evidence to guide conservation policy and management. Applied ecology is becoming increasingly quantitative and model selection via information criteria has become a common statistical modeling approach. Unfortunately, parameters that contain little to no useful information are commonly presented and interpreted as important in applied ecology. I review the concept of an uninformative parameter in model selection using information criteria and perform a literature review to measure the prevalence of uninformative parameters in model selection studies applying Akaike's Information Criterion (AIC) in 2014 in four of the top journals in applied ecology (Biological Conservation, Conservation Biology, Ecological Applications, Journal of Applied Ecology). Twenty-one percent of studies I reviewed applied AIC metrics. Many (31.5%) of the studies applying AIC metrics in the four applied ecology journals I reviewed had or were very likely to have uninformative parameters in a model set. In addition, more than 40% of studies reviewed had insufficient information to assess the presence or absence of uninformative parameters in a model set. Given the prevalence of studies likely to have uninformative parameters or with insufficient information to assess parameter status (71.5%), I surmise that much of the policy recommendations based on applied ecology research may not be supported by the data analysis. I provide four warning signals and a decision tree to assist authors, reviewers, and editors to screen for uninformative parameters in studies applying model selection with information criteria. In the end, careful thinking at every step of the scientific process and greater reporting standards are required to detect uninformative parameters in studies adopting an information criteria approach.

RESUMO

Neoliberal conservation has recently become a topic of academic research and a method of practice within the context of globalization. Less attention has been given to how neoliberal conservation has been practiced at the urban scale. This paper draws on the concept of 'urban-growth-oriented green grabbing' to capture the multidimensionality of the reasoning and process of ecological conservation in an urban growth context. It focuses on two ecological spatial protection plans for the DaPeng Peninsula in the city of Shenzhen, China. Through empirical investigation, this article traces the political economy of these plans and draws out the insights they offer regarding theories of urban environmentalism. The empirical results show that the ecological conservation plans are best understood as 'green grabbing' that has been achieved by land transfer and spatial interest redistribution. Conceptually, the paper provides further evidence of the process of neoliberal conservation within the urban context.

RESUMO

The United States Environmental Protection Agency (US EPA) has recently proposed changes to strengthen the transparency of its pivotal regulatory science policy and procedures. In this context, the US EPA aims to enhance the transparency of dose-response data and models, proposing to consider for the first time non-linear biphasic dose-response models. While the proposed changes have the potential to lead to markedly improved ecological risk assessment compared to past and current approaches, we believe there remain open issues for improving the quality of ecological risk assessment, such as the consideration of adaptive, dynamic and interactive effects. Improved risk assessment including adaptive and dynamic non-linear models (beyond classic threshold models) can enhance the quality of regulatory decisions and the protection of ecological health. We suggest that other countries consider adopting a similar scientific-regulatory posture with respect to dose-response modeling via the inclusion of non-linear biphasic models, that incorporate the dynamic potential of biological systems to adapt (i.e., enhancing positive biological endpoints) or maladapt to low levels of stressor agents.

RESUMO

Multi-stakeholder environmental management and governance processes are essential to realize social and ecological outcomes. Participation, collaboration, and learning are emphasized in these processes; to gain insights into how they influence stakeholders' evaluations of outcomes in relation to management and governance interventions we use a path analysis approach to examine their relationships in individuals in four UNESCO Biosphere Reserves. We confirm a model showing that participation in more activities leads to greater ratings of process, and in turn, better evaluations of outcomes. We show the effects of participation in activities on evaluation of outcomes appear to be driven by learning more than collaboration. Original insights are offered as to how the evaluations of outcomes by stakeholders are shaped by their participation in activities and their experiences in management and governance processes. Understanding stakeholder perceptions about the processes in which they are involved and their evaluation of outcomes is imperative, and influences current and future levels of engagement. As such, the evaluation of outcomes themselves are an important tangible product from initiatives. Our research contributes to a future research agenda aimed at better understanding these pathways and their implications for engagement in stewardship and ultimately social and ecological outcomes, and to developing recommendations for practitioners engaged in environmental management and governance.

RESUMO

AIM: The Convention on Biological Diversity (CBD) states the need to effectively conserve at least 10% of coastal and marine areas of particular importance for biodiversity by 2020. Here, a new indicator-based methodological framework to assess biodiversity protection afforded by marine protected areas' (MPA) was developed as a quick surrogate for MPAs' potential conservation effectiveness: the Marine Protected Area Protection Assessment Framework (MaPAF). The MaPAF consists of a limited number of headline indicators that are integrated in two indexes: Legal protection and Management effort, which eventually integrate in the overall MPA Protection super-index. The MaPAF was then tested in the Mediterranean MPA network as a case study. Spatial analyses were performed at three meaningful scales: the whole Mediterranean Sea, Mediterranean ecoregions and countries. The results of this study suggest that: 1) The MaPAF can serve as a useful tool for consistent, adaptive, quick and cost-effective MPA effectiveness assessments of MPAs and MPA networks in virtually any marine region, as the headline indicators used are commonly compiled and easy to retrieve; 2) The MaPAF proved usable and potentially relevant in the Mediterranean Sea where most indicators in the framework can be publicly accessed through the MAPAMED database and are planned to be regularly updated; 3) Protection afforded by MPAs is low across the whole Mediterranean, with only few MPAs having relatively high legal and managerial protection; and 4) Most Mediterranean countries need to devote substantially more work to improve MPA effectiveness mainly through increased management effort.

RESUMO

Technology and scientific advancements are accelerating changes in society at a pace that is challenging the abilities of government regulatory agencies and legal courts to understand the benefits and costs of these changes to humans, wildlife, and their environments. The social, economic, and political facets of concern, such as the potential effects of chemicals, complicate the preparation of regulatory standards and practices intended to safeguard the public. Court judges and attorneys and, in some cases, lay juries are tasked with interpreting the data and implications underlying these new advancements, often without the technical background necessary to understand complex subjects and subsequently make informed decisions. Here, we describe the scientific-quasi-judicial process adopted in Canada under the Canadian Environmental Protection Act, 1999, which could serve as a model for resolving conflicts between regulatory agencies and the regulated community. An example and process and lessons learned from the first Board of Review, which was for decamethylcyclopentasiloxane (D5; CAS# 541-02-06), are provided. Notable among these lessons are: 1) the need to apply state-of-the-science insights into the regulatory process, 2) to encourage agencies to continuously review and update their assessment processes, criteria, and models, and 3) provide these processes in guidance documents that are transparent and available to all stakeholders and generally foster closer cooperation between regulators, the academic community, industry, and nongovernment organizations (NGOs).

RESUMO

The concept of nature as capital is gaining visibility in policies and practices in both the public and private sectors. This change is due to an improved ability to assess and value ecosystem services, as well as to a growing recognition of the potential of an ecosystem services approach to make tradeoffs in decision making more transparent, inform efficient use of resources, enhance resilience and sustainability, and avoid unintended negative consequences of policy actions. Globally, governments, financial institutions, and corporations have begun to incorporate natural capital accounting in their policies and practices. In the United States, universities, nongovernmental organizations, and federal agencies are actively collaborating to develop and apply ecosystem services concepts to further national environmental and economic objectives. Numerous federal agencies have begun incorporating these concepts into land use planning, water resources management, and preparations for, and responses to, climate change. Going forward, well-defined policy direction will be necessary to institutionalize ecosystem services approaches in federal agencies, as well as to guide intersector and interdisciplinary collaborative research and development efforts. In addition, a new generation of decision support tools are needed to further the practical application of ecosystem services principles in policymaking and commercial activities. Improved performance metrics are needed, as are mechanisms to monitor the status of ecosystem services and assess the environmental and economic impacts of policies and programs. A greater national and international financial commitment to advancing ecosystem services and natural capital accounting would likely have broad, long-term economic and environmental benefits.
