Resilience Perception of a Mining Town in Eastern Amazonia: A Case Study of Canaã Dos Carajás, Brazil
13. Januar 2021
Abstract The ability of communities to react to risks and disturbances is for their balance, development, and sustainability. The concept of resilience provides a way to think about policies and actions for future changes in socioeconomic and ecological-environmental systems. This paper analyzes, in the context of mining, the perception of the resilience of Canaã dos Carajás population in Pará State, Brazilian Amazon. The methodology involved face-to-face interviews based on a structured questionnaire conducted on a sample of 140 residents stratified from 11 social...
Moving from Latent to Manifest Problem: Trajectories Across Scientific and Public Salience of Invasive Alien Species
12. Januar 2021
Abstract Who worries first about an invasive alien species: scientists or the general public, or do both become concerned simultaneously? Taking thirteen invasive alien species in the Netherlands, this article reconstructs the development of their public and scientific salience: the attention they attracted and the knowledge about them. Salience was assessed from the number of publications from 1997 onwards in the LexisNexis newspaper database and Scopus scientific database. Three trajectories were derived for a species to move from being a latent problem with low...
Application of Response Surface Methodology For Modeling and Optimization of A Bio Coagulation Process (Sewage Wastewater Treatment Plant)
12. Januar 2021
Abstract Cactus has shown great capabilities as a bio coagulant/flocculent in the treatment of wastewater and as a factor for sustainable development of the environment, due to its abundance and non-toxicity for human health. This has encouraged the present study based on the design of experiments to optimize the two operating factors: the bio coagulant dosage and initial pH. The effect of these considered factors on turbidity and chemical oxygen demand (COD) reduction performances was investigated to treat sewage wastewater from plants by the coagulation/flocculation...
Restoring Fringing Tidal Marshes for Ecological Function and Ecosystem Resilience to Moderate Sea-level Rise in the Northern Gulf of Mexico
11. Januar 2021
Abstract Tidal marshes are increasingly vulnerable to degradation or loss from eutrophication, land-use changes, and accelerating sea-level rise, making restoration necessary to recover ecosystem services. To evaluate effects of restoration planting density and sea-level rise on ecosystem function (i.e., nitrogen removal), we restored three marshes, which differed in elevation, at Weeks Bay National Estuarine Research Reserve, Alabama, USA and planted them with Juncus roemerianus sods at 0, 25, 50, 75, or 100% initial cover. We simulated future sea level using passive...
Developing a Conceptual Model for Sustainable water Resource Management and Agricultural Development: the Case of the Breede River Catchment Area, South Africa
11. Januar 2021
Abstract The complex relationship that exists between water resources and agricultural production has been increasing constantly globally. Several factors are interacting to influence the management of water resources making the system complex and dynamic. To increase the understanding of these complex and dynamic systems, relevant tools are needed to identify the causal relationships that exist between the drivers and their influences on the system. Participatory modelling based on the system dynamics approach provides a simplistic and visualisation tool that can improve...
Incorporating Network Connectivity into Stream Classification Frameworks
09. Januar 2021
Abstract Stream classification frameworks are important tools for conserving aquatic resources. Yet despite their utility, most classification frameworks have not incorporated network connectivity. We developed and compared three biologically informed stream classification frameworks considering the effects of variables indexing local habitat and/or connectivity on stream fish communities. The first framework classified streams according to local environmental variables largely following the precedent set by previous stream classifications. The second framework classified...
Source to Tap Risk Assessment for Intermittent Water Supply Systems in Arid Regions: An Integrated FTA—Fuzzy FMEA Methodology
07. Januar 2021
Abstract Water utilities in arid regions deal with multifaceted issues of natural groundwater contamination, high treatment costs, and low water rates. These utilities rely on intermittent supplies resulting in numerous water quality failures at source, treatment, distribution, and in-house plumbing systems. The present research presents an inclusive risk assessment methodology for managing water quality from source to tap. Three-year monitoring data for turbidity, TDS, pH, iron, ammonia, nitrates, residual chlorine, Coliform group, E. coli, and Fecal Streptococci...
Values Matter: The Role of Key Nodes of Social Networks in an Environmental Governance Case from Taiwan
05. Januar 2021
Abstract Social networks and related social processes play a critical role in natural resources and environmental governance. In this paper, an environmental governance case is analyzed from a social network perspective. We explore how social networks of proponents for and opponents against environmental regulations are formed and developed and how these social networks facilitate or hinder environmental regulations in different periods. The results reveal that government leaders with political power, the key node of the social network, can connect specific networks with...
Wetland Compensation and Landscape Change in a Rapidly Urbanizing Context
05. Januar 2021
Abstract While there are regulatory requirements that regulators should assess the impact of landscape-scale changes on the success of US Clean Water Act wetland compensatory mitigation sites, these requirements are poorly specified and very little work has been done to characterize how landscape change impacts CWA compensation sites. We created a rapid assessment method with both site-based and landscape-scale components, and used it to assess a population of wetland compensation sites in suburban St. Paul, Minnesota in 1997. We resampled the sites in 2010. The watersheds...
Evaluating the Ecological Benefits of Management Actions to Complement Environmental Flows in River Systems
05. Januar 2021
Abstract Globally, many river systems are under stress due to overconsumption of water. Governments have responded with programmes to deliver environmental water to improve environmental outcomes. Although such programmes are essential, they may not be sufficient to achieve all desired environmental outcomes. The benefits of environmental water allocation may be improved using ‘complementary measures’, which are non-flow-based actions, such as infrastructure works, vegetation management and pest control. The value of complementary measures is recognised globally, but...
Process Makes Perfect: Perceptions of Effectiveness in Collaborative Environmental Governance
04. Januar 2021
Abstract In evaluating effectiveness for collaborative environmental governance arrangements, a key concern is describing not just the processes and actors that are a part of these systems, but also the impacts that these processes have on ecological and social conditions. Existing research delineates an emphasis on process variables over outcome variables, as well as the difficulties of demonstrating causal relationships between collaborative governance processes and ecological outcomes. In this paper, we examined how process and outcome criteria are used by sponsors...
Heavy Metals and Trace Elements in Whole-Blood Samples of the Fishermen in Turkey: The Fish/Ermen Heavy Metal Study (FHMS)
07. Dezember 2020
Abstract Selected heavy metal-trace element (Ag, As, Ba, Cd, Cu, Hg, Pb, Sb, Se, Sr, and V) levels were determined by the ICP-MS method in whole-blood samples of fishermen and control group who accommodate in four provinces of the Marmara Sea. Mercury (1.267 ± 1.061 µg/L to 0.796 ± 0.853 µg/L) and lead (17.8 ± 9.0 µg/L to 12.0 ± 6.83 µg/L) levels were higher in the fishermen group than that of control group (p < 0.001 for both). There was no difference between the fishermen group and the control group in terms of whole-blood levels...
A Coastal Vulnerability Framework to Guide Natural Infrastructure Funds Allocation in Compressed Time
04. Dezember 2020
Abstract Hurricane Maria, a category 4 tropical cyclone, hit the US non-incorporated territory of Puerto Rico on September 20, 2017. Widespread physical and natural infrastructure damage was observed, especially in already vulnerable coastal communities. As public sector funding availability for natural infrastructure (ex. coastal ecosystems) increases, mechanisms for its efficient and equitable allocation are lacking. An accessible and replicable coastal vulnerability indicator framework is presented to assist state and federal policy makers in the allocation of funding...

Shrub Encroachment Following Wetland Creation in Mixedgrass Prairie Alters Grassland Vegetation and Soil
01. Dezember 2020
Abstract Wetland decline under post-European settlement and land use change across western Canada has led to mitigation strategies, including wetland creation. Created wetlands can trigger environmental change, including woody species encroachment, in turn altering vegetation and soil. We quantify changes in shrub abundance from prior to wetland creation (1949) until 60 years later (2012) within a Mixedgrass ecosystem of the Verger watershed in Alberta, Canada. In addition, we compare remaining grassland with areas colonized by shrubland on similar ecosites for...
Beliefs in Conflict: The Management of Teno Atlantic Salmon in the Sámi Homeland in Finland
01. Dezember 2020
Abstract The subarctic Teno River is one of the most significant spawning rivers for Atlantic salmon in Europe. In 2009, research indicated that the Teno salmon stock was in a weak state, and concern about the future of Atlantic salmon in the Teno River arose on both sides of the river, in Finland and Norway. In 2017, the governments ratified the new Teno fishing agreement (Teno Fishing Act 2017). The agreement aimed to reduce the fishing volume by 30%, and the new regulations concerned all users, including the indigenous Sámi, other locals, tourists, and fishing...
Green Credit, Financial Constraint, and Capital Investment: Evidence from China’s Energy-intensive Enterprises
01. Dezember 2020
Abstract The green credit policy is an important green financial tool that can achieve the win–win scenario with economic development and environmental protection through the reasonable allocation of credit resources. Using the green credit guidelines (GCGs) in China as a quasi-natural experiment, this study explored the impacts of the green credit policy on the capital investment of energy-intensive enterprises in a difference-in-differences framework and established the mediation effect model to analyze the mechanisms. The empirical results showed that the capital...
The Evolution of Policy Instruments for Air Pollution Control in China: A Content Analysis of Policy Documents from 1973 to 2016
01. Dezember 2020
Abstract China’s portfolio of air-pollution control policy instruments has gradually broadened since the 1970s from regulatory instruments to include numerous market-based and voluntary policy instruments. We demonstrate this broadened portfolio of policy instruments for air-pollution control with a computer-assisted content analysis of 148 central-level policy documents from 1973 to 2016. We identify 20 types of policy instruments in these documents, and analyze such things as their historical evolution, main subjects, frequency of use, and whether they were issued...
Use of Local Ecological Knowledge to Detect Declines in Mammal Abundance in Kogyae Strict Nature Reserve, Ghana
01. Dezember 2020
Abstract The scarcity of environmental data means that other sources of information are needed to complement empirical evidence for conservation decisions. We, therefore, aimed to explore Local Ecological Knowledge (LEK) on mammal abundance and qualitative population trends through interviews from 331 local people in and around Kogyae Strict Nature Reserve, Ghana. The results show that 62% of the respondents perceived that mammal abundances had decreased, 31% perceived stability, and 8% perceived that mammals had increased between 2006 and 2017. The respondents...
Assessment of Heavy Metal Pollution in Soil and Classification of Pollution Risk Management and Control Zones in the Industrial Developed City
01. Dezember 2020
Abstract Soil heavy metal pollution threatens ecological health and food security. It is significant to classify pollution risk management and control zones, which can effectively cope with soil pollution and scientifically carry out soil remediation projects. In this study, based on 665 soil samples collecting from Ningbo (southeast China), single pollution index and Nemerow composite pollution index (NCPI) were measured to assess soil pollution risk, and self-organization mapping model was applied to classify management and control zones. Results showed that the heavy...
