Satellite data are vital for understanding the large-scale spatial distribution of PM2.5 due to their low cost, wide coverage, and all-weather capability. Estimation of particulate matter (PM2.5) using satellite aerosol optical depth (AOD) product is a popular method. In this paper, we review the PM2.5 estimation process based on satellite AOD data in terms of data sources (i.e., inversion algorithms, data sets and interpolation methods), estimation models (i.e., statistical regression, chemical transport models, machine learning and combinatorial analysis) and modeling validation (i.e., four types of cross-validation (CV) methods). We found that the accuracy of time-based CV is less than others. We found significant differences in modeling accuracy between different seasons (p<0.01) and different spatial resolutions (p<0.01). We explained these phenomena. Finally, we summarized the research process, present challenges and future directions in this field. We opined that low-cost mobile devices combined with transfer learning or hybrid modeling offered research opportunities in areas with limited PM2.5 monitoring stations and historical PM2.5 estimation. These methods can be a good choice for air pollution estimation for developing countries. The purpose of this study is to provide a basic framework for future researchers to conduct relevant research, enabling them to understand current research progress and future research directions.

Greenhouse gas (GHG) emissions from the Agriculture, Forest, and Other Land Use (AFOLU) sector account for 23% of net global anthropogenic emissions. However, effective conservation agriculture practices can sequester carbon (C) up to one meter in soil depth and vegetation biomass. Integrated Crop-Livestock-Forestry (ICLF) systems attempt to ensure sustainable agricultural production by combining various agricultural, livestock, and forestry production systems. This bibliographic review aims to present and discuss ICLF systems, and their advantages and disadvantages compared to conventional systems, achieving a better understanding of the sources and sinks of greenhouse gasses (CH4, N2O, and CO2). Integrated systems exist in tropical and temperate climates, with different practices, arrangements, designs, and modalities. Intercropping species with different root structures provide more ecological interactions that enhance biodiversity, soil quality, and C sequestration while reducing GHG emissions. Yet, ICLF systems are complex and require technical assistance and support for being implemented, besides an extensive initial investment that increases the cost of operation. A relevant carbon sink in ICLF systems is carbon from tree biomass, where the wood can be used for various purposes. Timber for sawmills and general construction has a longer C immobilization time. Methane from enteric fermentation is the greatest contributor to GHG emissions in livestock and ICLF systems. Nitrous oxide is released primarily from synthetic fertilizers (when applied), manure deposited on pastures, and decomposition of plant residues. Carbon dioxide is emitted to a lesser extent from the application of lime and urea. Many studies do not include all compartments in the C balance and often focus on only one GHG or compartment of C. Accordingly, more studies on the sources and sinks of C and their potential to offset GHG emissions in terms of CO2 equivalent are urged.

Similar to many freshwater ecosystems, the Laurentian Great Lakes of North America have undergone numerous anthropogenic stressors resulting in considerable loss of biodiversity and habitat. Among Great Lakes fishes, the coregonine sub-family has endured the most extensive declines, including extinction of several species ( Coregonus johannae, C. alpenae, and C. kiyi orientalis) and at least 10 instances of local extirpations of other species ( C. nigripinnis, C. reighardi, C. zenithicus, C. hoyi, and C. artedi) across all 5 lakes, much of which occurred prior to the 1960s owing to overfishing, interactions with non-indigenous species, and habitat loss. Despite these declines, no federal-, provincial-, or state-mandated actions were ever implemented to conserve coregonine diversity, potentially because so much of the coregonine declines occurred prior to the enactment of federal conservation legislation. Possible explanations for inaction since enactment of that legislation include insufficient data on biological vulnerability or threats, unresolved taxonomy, and limited support from the fishery management agencies and their stakeholders prior to the 2000s. In recent decades, however, several fishery management agencies have undertaken efforts to re-introduce coregonine diversity. These efforts helped lead to development of a science-based framework to restore coregonines that was universally endorsed by fishery managers representing eight U.S. states, four U.S. tribal organizations, and the province of ON, Canada, in May 2018. The basin-wide framework is based on principles of conservation biology and adaptive management. We describe details of its key steps, including planning, restoring, and evaluating, while also describing recent implementation efforts to develop methods, improve available resources, and enhance coordination across the basin. Although our paper describes a regional effort to restore native coregonines, our adaptive-management approach could be used by other multi-agency stakeholders seeking to conserve or restore native fishes.

Climate change scenarios established by the Intergovernmental Panel on Climate Change (IPCC) have developed a significant tool for analyzing, modeling, and predicting future climate change impacts in different research fields after more than 30 years of development and refinement. In the wake of future climate change, the changes in forest structure and functions have become a frontier and focal area of global change research. This study mainly reviews and synthesizes climate change scenarios and their applications in forest ecosystem research over the past decade. These applications include changes in 1) forest structure and spatial vegetation distribution, 2) ecosystem structure, 3) ecosystem services, and 4) ecosystem stability. Although climate change scenarios are useful for predicting future climate change impacts on forest ecosystems, the accuracy of model simulations needs to be further improved. Based on existing studies, climate change scenarios are used in future simulation applications to construct a biomonitoring network platform integrating observations and predictions for better conservation of species diversity.

Military training areas (MTA) are special environments with specific anthropogenic activities. The aims of this review are (1) to understand the interactions between military training activities and biodiversity, (2) to quantify the available scientific literature on this subject, (3) to highlight the origin of the studies. Queries were carried out on two literature databases: Scopus and Wiley. The queries returned a large number of papers, but few actually matched the research topics. These two databases contain nearly 400 articles that discuss the interactions between military training and biodiversity at different scales. These articles come from all over the world, but the majority were conducted in the United States. In Europe, the studies are mainly conducted on German, English and Czech sites. Impacts on biodiversity from all types of military training and from restricted areas were studied. The impacts on these areas are multiple and affect the landscape, the soil, fauna and flora. They can be directly or indirectly related to military activities. Responses to disturbance by military trainings can be complex as they are variable. Thus, the same training may result in positive, neutral or negative impacts depending on the habitats or taxa targeted and the country studied. Training methods are constantly evolving and vary between countries, it appears important to maintain research about conservation in those particular areas, which paradoxically represent opportunities for nature conservation.

Covering 55% of Canada’s total surface area and stretching from coast to coast to coast, the Canadian boreal zone is crucial to the nation’s economic and ecological integrity. Although often viewed as relatively underdeveloped, it is vulnerable to numerous stressors such as mining, forestry, and anthropogenic climate change. Natural archives preserved in lake sediments can provide key insights by quantifying pre-disturbance conditions (pre-1850 CE) and the nature, magnitude, direction, and speed of environmental change induced by anthropogenic stressors over the past ~150 years. Here, we paired a review of paleolimnological literature of the Canadian boreal zone with analyses of published sediment core data to highlight the effects of climate change, catchment disturbances, and atmospheric deposition on boreal lakes. Specifically, we conducted quantitative syntheses of two lake health indicators: elemental lead (Pb) and chlorophyll a. Segmented regressions and Mann-Kendall trend analysis revealed a generally increasing trend in elemental Pb across the boreal zone until ~1970 CE, followed by a generally decreasing trend to the present. Snapshot comparisons of sedimentary chlorophyll a from recent and pre-industrial sediments (i.e., top-bottom sediment core design) revealed that a majority of sites have increased over time, suggesting a general enhancement in lake primary production across the boreal zone. Collectively, this body of work demonstrates that long-term sediment records offer a critical perspective on ecosystem change not accessible through routine monitoring programs. We advocate using modern datasets in tandem with paleolimnology to establish baseline conditions, measure ecosystem changes, and set meaningful management targets.

As we enter the United Nations Decade of Ecosystem Restoration, the need to engage in restoration activities has never been greater. Included within this need is a requirement for clear communication between researchers, practitioners, policymakers, stakeholders, and community members. To facilitate the discussion and assessment of restorative activities, we propose two decision trees to differentiate between key restoration terms (Reclamation, Rehabilitation, Ecological Restoration, Rewilding, Landscape Restoration, Intra-Ecosystem Restoration, Reference Condition Restoration, and Ecological Reclamation) and to clarify how they relate to each other, based upon project scope and desired/intended project outcomes. Continued use of unclear terminology impedes practitioners or researchers from using the literature efficiently, to find precedents that could assist their current efforts. As such, increasing clarity of communications will ensure restoration is discussed within a framework of well-defined and agreed upon terms. It is our hope that this suggested framework will contribute to the ongoing and much needed terminology debate and help enhance cohesion on the use of key terms within the restoration focused literature. Given the increased focus upon restoration projects of any kind, especially during the UN's decade of ecosystem restoration, it is more important than ever that restoration practitioners speak the same language.

Western-trained, non-Indigenous researchers in Canada have an ethical responsibility to collaborate with Indigenous Peoples and to re-envision the scientific research process through the lens of reconciliation. The health of the natural environment has long been a concern to both Indigenous and non-Indigenous Peoples, and weaving different ways of knowing could provide a path forward to address critical wildlife health concerns. Here, we conducted a review of the peer-reviewed and grey literature that claims to weave Indigenous and Western ways of knowing in ecotoxicology and wildlife health in Canada, coding for background information, wildlife health stressors, research methods, Indigenous participation, and research outcomes. Seventeen studies met the inclusion criteria, the majority of which were published since 2015 and took place in Canada’s North. Research collaborations were often between First Nations or Inuit knowledge holders (most frequently, active harvesters and Elders) and Western-trained, non-Indigenous academics. Most studies were initiated by mutual agreement between community partners and researchers, but no study was “Indigenous-led” at any stage of research. Studies investigated environmental contaminants and health-related topics in a range of wildlife, usually traditional subsistence species. The most commonly studied disease was avian cholera, and the most studied class of toxicants was metals and trace elements. Indigenous knowledge was primarily collected via interviews. Studies often used multiple methodologies to braid or weave knowledge, but the most frequently used methodology was community-based participatory research. To provide a more holistic understanding of the process of weaving knowledge, we conducted an in-depth examination, applying a decolonizing lens, of two exemplar cases of collaborative research with Indigenous communities. This exploration led to the conclusion that research that weaves ways of knowing must not be approached with a “one-size-fits-all” mindset, but instead should emphasize relationship building, continuous engagement, and ethical practices. By adopting such practices, Western-trained, non-Indigenous academics can better address critical wildlife health concerns while contributing meaningfully to advancing healing and reconciliation with Indigenous Peoples.

The health of the natural environment has long been a concern to both Indigenous and non-Indigenous Peoples, and weaving different ways of knowing could provide a path forward to address critical wildlife health concerns. Here, we conducted a review of the peer-reviewed and grey literature that claims to weave Indigenous and Western ways of knowing in ecotoxicology and wildlife health in Canada, coding for background information, wildlife health stressors, research methods, Indigenous participation, and research outcomes. Seventeen studies met the inclusion criteria, the majority of which were published since 2015 and took place in Canada’s North. Research collaborations were often between First Nations or Inuit knowledge holders (most frequently, active harvesters and Elders) and Western-trained, non-Indigenous academics. Most studies were initiated by mutual agreement between community partners and researchers, but no study was “Indigenous-led” at any stage of research. Studies investigated environmental contaminants and health-related topics in a range of wildlife, usually traditional subsistence species. The most commonly studied disease was avian cholera, and the most studied class of toxicants was metals and trace elements. Indigenous knowledge was primarily collected via interviews. Studies often used multiple methodologies to braid or weave knowledge, but the most frequently used methodology was community-based participatory research. To provide a more holistic understanding of the process of weaving knowledge, we conducted an in-depth examination, applying a decolonizing lens, of two exemplar cases of collaborative research with Indigenous communities. This exploration led to the conclusion that research that weaves ways of knowing must not be approached with a “one-size-fits-all” mindset, but instead should emphasize relationship building, continuous engagement, and ethical practices.

In this paper, Indigenous engagement in renewable energy projects is reviewed and the main elements of energy partnerships between various stakeholders and Indigenous partners are discussed. In recent years Canada has witnessed more significant Indigenous involvement in economic and energy development projects than ever before. The key components of large-scale energy partnerships focus on community engagement, financial capital, community buy-in (readiness with entrepreneurial and business skills) and benefits-sharing with community partners. Equity-ownership, reconciliation and self-determination intersect with and impact the benefits and sustainability of energy projects as they are interrelated in the framework of most energy partnerships. In addition, this paper illustrates features of energy projects in the literature and policy disconnects in connection with partnership-making, social outcomes, and decision making among Indigenous communities. Furthermore, findings from the literature explore the nuanced discourse on social implications and capacity challenges that interlink with reconciliation when promoting large-scale renewable energy partnerships with Indigenous communities. Through systematic review and meta-analysis of the literature, we found eighty relevant items during the screening process and selected thirty-three for the analysis. Findings demonstrate that the Crown, energy companies and community partners need to coordinate and collaborate closely to achieve energy security and sustainable renewable energy in the near future. The review suggests that Indigenous engagement in energy partnerships supports positive outcomes for social development and environmental protection among Indigenous communities. Further, when government and industry partners mentor in the project implementation process, as well as help other communities, large-scale positive impacts on energy transitions and self-sufficiency can be realized.
