The excessive consumption of resources and the destruction of ecological environment in mining areas have severely restricted coal mining, and the research on resource and environmental carrying capacity (RECC) of mining areas is of great significance in reconciling coal mining and resource environmental protection. To review the existing research on the RECC of mining areas, the concepts of the RECC were elaborated, and then the development process and application areas of both resource carrying capacity (RCC) and environmental carrying capacity (ECC) were studied. The main methods and models involved in the RECC study were counted. The results showed that the research on the RECC of mining areas has not attracted sufficient attention, and the relevant literature is relatively few. The existing research on RECC in mining areas mainly adopts single-factor analysis, which makes it difficult to comprehensively evaluate the overall situation of RECC in mining areas. Thus, a comprehensive evaluation of the RECC of mining areas by scientific evaluation methods is required to ensure the coordinated development of coal production, resources and environment of mining areas. This review provides an important reference and guidance for the necessity and thinking of the comprehensive study of resources and environment carrying capacity in mining areas.

The governance of flood resilience comprises an array of policy instruments that can be applied to reduce damages and risks to the communities. Policy instruments available at the local level tend to have the greatest impact on communities’ ability to absorb shock and resume normal operation. This study is the first attempt to analyze policy instruments and regulations guiding the progression of flood resilience measures in the Okanagan Valley, BC. It aims to offer recommendations specific to the local context and identify the best practices to improve flood resilience of the communities. Therefore, the study adopted a multistage methodology including literature review, stakeholder consultations with the organizations (consisting of municipalities, regional districts and First Nations) and quantitative analysis using present/absent criteria to measure prevalence of given indicators and five flood resilience classes. The results suggest that the flood resilience policies and strategies of 22 organizations in the Okanagan valley are predominantly focused on flood preparation and mitigation, whereas policies related to during and post-flood management are still in the infancy and do not offer satisfactory support. Notably, some organizations are proactive in recognizing looming flood risks, thus enacting essential policy measures to strengthen resilience. These results further highlight that these organizations have focused on a variety of measures to improve resilience, such as spatial planning, building construction setbacks, enhancing natural environment, protecting riparian areas, and stormwater management. As well, current flood resilient practices by the Prairies (Calgary) paved the way of how both regions can learn from each other. The study sheds lights on broader takeaways of what the findings of this study mean for other world regions. The study results are of great importance to the organizations across the Okanagan Valley as they lay the groundwork for resource mobilization to achieve flood resilience and sustainability.

This review paper aims at understanding natural and anthropogenic sources of rare earth elements (REEs) in the environment, their mechanisms of action, individual toxicity of REEs and individual toxicity of their mixtures, including with other toxicants. We also summarized the scientific knowledge on REE bioaccumulation by plants, animals and fungi. The purpose of the work was to analyze published scientific information and identify unsolved scientific issues in the selected areas. At present, both natural positive geochemical anomalies of REEs and "spots" of anthropogenic origin are discovered. There is a relationship between natural and anthropogenic sources of REEs in the environment. Increasing REE mining leads to the exposure of rock layers rich in target elements, which are then leached from natural and waste rocks. As a result, the total content of REEs in soils of their extraction areas reaches 2.3 µg/kg, and in the snow of cities it is found from 0.411 µg/kg to 1.463 µg/kg, which is comparable with natural anomalies of elements. Most often such levels of REE accumulation are not dangerous for biota. REEs, like many trace elements, have an essential effect in low concentrations and have harmful effects only when the dose is increased. However, stimulation effects proven for agricultural plants and animals in the natural environment can influence the change in population and community structures. The effects of REE compounds have many uncertainties under the conditions of their joint action with each other and with other substances containing biogenic or potentially toxic elements. The article provides examples of additive, synergistic and antagonistic action of a mixture of elements. Further, it is shown that the bioaccumulation of REEs is comparable to the accumulation of heavy metals in living organisms. Data on the transfer of REEs along trophic chains are single and contradictory. Thus, REEs contribute to the toxic load on living organisms. The main “blank spots” in knowledge about the action of REEs that require further research are identification of the most sensitive and vulnerable species, establishment of long-term effects, and clarification of the joint action of REEs with other substances.

Azolla is often considered an invasive weed because of the rapid colonization of water surfaces. It is a free-floating aquatic fern, known for its N fixing potential, short doubling time, and bioremediation potential. It has several applications as green manure, N biofertilizer, cattle, chicken, and fish feed supplements because of its high protein content. It can grow on wastewater improving its quality. Azolla biomass thus produced can be utilized for energy production. It has been used for the production of biogas. Recently, its bio-oil potential has been studied. Azolla biomass has been used for biodiesel, biogas, and bio-hydrogen production. The exploitation of Azolla biomass as feedstock for bioenergy needs critical evaluation.

Environmental Impact Assessments (EIA) aim to assess the predicted effects of future projects on the environment, human health, and the economic potential of a region. They are an instrumental tool for sustainable development and to reduce the impact of large-scale industrial projects on biodiversity. The accurate assessment of the effects of projects on wildlife populations has a variety of ecological, cultural, and economic implications. However, assessments are commonly done using indirect indicators like the predicted impact of changes in the quantity and quality of wildlife habitat and/or predicted changes in non-specific wildlife population metrics (e.g., relative abundance). In recent decades, the interpretation of wildlife health has moved from the classical dichotomous state of “disease presence/absence’’ to a broader concept that integrates the interaction of biological, social and environmental health determinants. We sought to determine how wildlife health metrics are used in EIA processes and propose a framework to characterize, quantify and monitor wildlife health in future EIAs. First, we performed a targeted review of EIAs documents from three jurisdictions in Canada to characterize the relevance and use of ‘wildlife health’ in these documents. Then, we reviewed case studies and research examples to understand wildlife health in different contexts associated with conservation biology to propose a framework to incorporate wildlife health into baseline monitoring and mitigation processes in EIAs. Our targeted review illustrates that while wildlife health and related terminology is often invoked in the main and specific objectives of EIAs, it is rarely tracked and quantified in EIAs and related processes. We identified approaches that can be used to effectively incorporate wildlife health in EIAs, including context-specific wildlife health metrics, participatory epidemiology, community-based sampling, and Local Ecological Knowledge. We illustrate case studies where wildlife health can facilitate the inclusion of communities, Indigenous governments, and Local Ecological Knowledge into the evaluation process of projects and developments and into co-management practices of wildlife. Our work highlights the critical need to move towards incorporating wildlife health into EIA processes to provide a more direct and holistic perspective on the potential environmental impacts and improve the opportunities for early implementation of mitigation measurements.

Emerging pollutants (EPs) are the contaminants of concern in water systems. These are mainly due to anthropogenic activities and are not always removed during water treatment, eventually affecting the quality of water supply systems (WSSs). These pollutants vary from organic pollutants such as pharmaceuticals, pesticides, and flame retardants to inorganic pollutants like heavy metals or illicit drugs. Currently, there is a lack of adequate research on the chronic health effects of these pollutants. In addition, climate change plays a role in immobilizing these pollutants. Consequently, considering the increasing effects visible in many countries, the rising levels of contaminants have strained the effectiveness of water treatment facilities. As water supply is an essential service to communities, it is necessary to ensure the reliability against risks of EPs. Therefore, it is important to protect the health and safety of consumers. Climate change has brought threats to water infrastructures, like many others. This review examined the effect of climate change on EPs in water supplies by providing a detailed review of the contaminants, evaluating their potential toxicity, and determining the appropriate water treatment technologies. The role of the WSS in EP immobilization was examined in addition to the potential effect of climate change. This review of different critical and relevant literature aids with the identification of current research gaps. Based on the identified gaps, a research framework was developed for the future investigation of EPs.

The relationship between traffic and forest road erosion has been studied for decades, and the answer to the question “what happens when traffic is present on these unpaved forest roads?” is simple: erosion increases. However, the answer to the question “why does it increase?” is complex and requires us to consider forest road erosion through an integrated lens. Fully understanding how traffic affects forest road erosion will allow us to control forest road erosion effectively. In this synthesis, we look at forest road erosion literature and focus the discussion on the interactions between traffic and erosion. Specifically, we explore four main hypotheses that have been proposed to explain how traffic affects erosion. These hypotheses are discussed in detail, including what data and information are required to evaluate them. In addition to the specific traffic-erosion interactions, we review important factors that interact with traffic to enhance erosion. Finally, we propose a framework that describes forest road erosion as a combination of all limiting factors. This framework can help guide future data collection needs, allow us to form a more holistic understanding of forest road erosion, and ultimately improve predictions of erosion from forest roads.

This article applies the tools of bibliometric analyses to explore the evolution and strategic orientation of research focusing on the temporal dynamics of land use, which can be considered as an important proxy to assess soil vulnerability. With 1416 papers published in 417 different journals, the investigation showed a growing interest in the subject during the period ranging from 2001 to 2020. The main countries working on that topic are USA, China and certain countries of the European Union with a worldwide collaboration regarding co-authors. A cluster analysis of the keywords generated 6 main themes of research, each focusing on different issues and approaches i.e greenhouse gas (GHG) emissions, soil nutrients, climate change, erosion risk, human disturbances as well as resilience of soil functioning. Finally, it appears that the effect of land use legacy is poorly considered in the context of climate change, which could represent a future line of research.

The increasing number of studies covering different life cycle sustainability assessment (LCSA) tools and urban water systems (UWSs) emphasize the need to synthesize current research. While LCSA studies focus on an integrated approach considering the life cycle assessment (LCA), Life Cycle Costing (LCC), and social life cycle assessment (S-LCA) methodologies, these tools are typically applied separately, disregarding the trade-offs amongst economic, social, and environmental impacts. In this context, this review aims to critically analyze the literature on LCSA tools to enhance the integrated application in the future. Furthermore, we aim to identify technological trends, current challenges, and future research directions to improve sustainability. The ProKnow-C methodology was applied using a combination of four keyword sets and three databases. We selected 72 relevant papers that were analyzed in detail. Results demonstrate that authors apply different boundaries when using different LCSA tools, and lack of data was also a common issue. Furthermore, papers lack system description in the scope definition, leading to a biased interpretation of results. Another important issue was the functional unit selection, which did not represent the complexity of UWSs, lacking important details such as water loss, water quality, and population served. Water treatment is the most researched process in UWSs, and stormwater systems (collection or treatment) are rarely included, representing only 25% of the analyzed literature. In conclusion, the application of LCSA tools faces fundamental challenges, such as data quality and availability. Concerning the engineering improvements, future works should use LCSA data to support design and technology development, also focusing on human behaviour and frugal technology alternatives. Finally, new paradigms need to be developed and applied to enhance sustainability and integrate UWS.

Wildfires are a natural landscape disturbance in many climates and forest types, but the cumulative impact of human-caused climate change, historical fire management and suppression, and changing species diversity in forests has led to an increase in the size and/or severity of wildfires in certain regions across the globe. There are a significant number of research studies on the effects of wildfire on human health, forest ecology, hydrology, and the physical, chemical, and biological properties of soils. However, research on the impact of wildfire on watersheds including toxicity in aquatic organisms, water chemistry, and fluvial sediment quality is less extensive, focusing primarily on water quality indicators such as nutrients and sediment flux. Recent research has shown that wildfires contribute to the environment significant amounts of polycyclic aromatic hydrocarbons (PAHs), which are compounds produced during the incomplete combustion of organic material, and are known to be toxic and mutagenic compounds. The primary objective of this paper is to review the recent literature that pertains to the contamination of surface waters and sediments, and source apportionment of wildfire-derived PAHs to determine where research gaps remain. Additional objectives are to assess the use of molecular ratios to apportion PAH sources, and finally, to create a roadmap for future studies in designing and conducting research that seeks to determine sources of wildfire-derived PAHs in water and sediment.
