Municipalities and cities face myriad challenges with regard to planning; decisions that will have long-standing consequences need to be made in the context of pressing present concerns, constrained budgets, and uncertainty about the future under climate changes. Compounding the challenge may be a lack of clear signals from the state and federal leadership on investment priorities. This paper contends that existing strategies from decision science can prove useful for local governments as they seek actions that are robust to uncertain futures and broadly beneficial across sectors and time horizons...

Recent national regulatory assessments of potential pesticide exposure of threatened and endangered species in aquatic habitats have led to increased need for watershed-scale predictions of pesticide concentrations in flowing water bodies. This study was conducted to assess the ability of the un-calibrated Soil and Water Assessment Tool (SWAT) to predict annual maximum pesticide concentrations in the flowing water bodies of highly vulnerable small- to medium-sized watersheds. SWAT was applied to 27 watersheds, largely within the Midwest corn belt of the US, ranging from 20-386 km2 , and evaluated using consistent input datasets and an un-calibrated parameterization approach...

The Trump administration's strategy to disengage and downplay the Paris Climate Agreement will likely result in a slight decrease in the already low levels of US news media global warming coverage. This is because significant limitations with the news media's ability to adequately cover climate change predated the administration. First, studies indicate that advertising interests and editors have always challenged journalists' abilities to adequately report on climate change issues. Instead of climate change stories, editors often prefer more sensational topics that garner higher ratings and approval with advertisers...

Microalgae play a pivotal role in the regulation of Earth's climate and its cycles, but are also affected by climate change, mainly by changes in temperature, light, ocean acidification, water stratification and precipitation-induced nutrient inputs. The changes and impacts on microalgae communities are difficult to study, predict and manage; but there is no doubt that there will be changes. These changes will have impacts beyond microalgae communities and many of them will be negative. Some actions are currently ongoing for the mitigation of some of the negative impacts, such as Harmful Algal Blooms and water quality, but global efforts for reducing CO2 emissions, temperature rises and ocean acidification are paramount for reducing the impact of climate change on microalgae communities, and eventually, on human wellbeing...

Recent studies showed cultural worldviews are a key determinant of environmental risk perceptions; thus, they could influence climate change adaptation strategies. African traditional worldviews encourage harmony between humans and the environment through a complex metaphysical belief system transmitted through folklore, taboos, and traditional knowledge. However, African traditional worldviews hold a belief in traditional gods that was shown to have a low connectedness to nature and low willingness to change...

This commentary examines recent shifts in air temperature data coinciding with high-magnitude precipitation events at climate stations spanning an elevational and longitudinal gradient on British Columbia's south coast. Results presented show that high-magnitude winter precipitation events are occurring on the south coast of British Columbia under progressively warmer conditions. In the future, proportionally more winter precipitation is anticipated to report as rainfall versus snow, and over time these changes will have a marked impact on the snow-melt dominated hydrographs that characterize local watersheds...

Regulation of agriculture irrigation water discharges in California is assessed and controlled by its nine Regional Water Quality Control Boards under the jurisdiction of the California State Water Resources Control Board. Each Regional Water Board has developed programs to control pesticides in runoff as part of the waste discharge requirements implemented through each Region's Irrigated Lands Regulatory Program. This study assessed how pesticide use patterns differ in the Imperial (Imperial County), Salinas and Santa Maria (Monterey County) valleys, which host three of California's prime agriculture areas...

PURPOSE: For the past twenty years the life cycle assessment (LCA) community has sought to integrate impacts on biodiversity into the LCA framework. However, existing impact assessment methods still fail to do so comprehensively, as they only quantify few impacts related to specific species and specific regions. This paper proposes a methodological framework that will allow LCA practitioners to assess currently missing impacts on biodiversity on a global scale. METHOD: Building on existing models which seek to quantify the impacts of human activities on biodiversity, the herein proposed methodological framework consists of two components: a habitat factor for 14 major habitat types and the impact on the biodiversity status in those major habitat types...

Two organophosphate pesticides, chlorpyrifos and malathion, are currently undergoing re-registration in the United States and were recently used by the Environmental Protection Agency (USEPA) as case studies to develop a national procedure for evaluating risks to endangered species. One of the endangered bird species considered by the USEPA was the Kirtland's warbler (Setophaga kirtlandii). The Kirtland's warbler is an endangered migratory species that nests exclusively in young jack pine stands in Michigan and Wisconsin, and winters in the Bahamas...

A probabilistic risk assessment (PRA) was performed to evaluate the range of potential baseline and post-remedy health risks to fish consumers at the Portland Harbor Superfund Site (Site). The analysis focused on risks of consuming fish resident to the Site containing polychlorinated biphenyls (PCBs), as this exposure scenario and contaminant are the primary basis for USEPA's selected remedy per the January 2017 Record of Decision (ROD). The PRA used probability distributions fit to the same data sets used in the deterministic baseline human health risk assessment (BHHRA) as well as recent sediment and fish tissue data to evaluate the range and likelihood of current baseline cancer risks and non-cancer hazards for anglers...

The California red-legged frog (CRLF), delta smelt (DS), and the California tiger salamander (CTS) are three species listed under the United States Federal Endangered Species Act (ESA), all of which inhabit aquatic ecosystems in California. The US Environmental Protection Agency (USEPA) has conducted deterministic screening-level risk assessments for these species potentially exposed to malathion, an organophosphorus insecticide and acaricide. Results from our screening-level analyses identified potential risk of direct effects to DS as well as indirect effects to all three species via reduction in prey...

This analysis focused on evaluating the environmental consequences of remediation; providing indicators for the environmental quality pillar of three 'pillars' of the Portland Harbor Sustainability Project (PHSP) framework (the other two pillars are economic viability and social equity). It included an environmental impact and benefit analysis (EIBA) and an EIBA-based cost-benefit analysis. Metrics developed in the EIBA were used to quantify and compare remedial alternatives' environmental benefits and impacts in the human and ecological domains, as a result of remedial actions (relative to no action)...

Regulatory decisions on remediation should consider affected communities' needs and values, and how these might be impacted by remedial options; this process requires that diverse stakeholders are able to engage in a transparent consideration of value trade-offs and of the distribution of risks and benefits associated with remedial actions and outcomes. The Stakeholder Values Assessment (SVA) tool was developed to evaluate remedial impacts on environmental quality, economic viability and social equity in the context of stakeholder values and priorities...

This paper describes a methodology for evaluating impacts of Superfund remedial alternatives on the regional economy in the context of a broader sustainability evaluation. Although economic impact methodology is well established, some applications to Superfund remedial evaluation have created confusion because of seemingly contradictory results. This confusion arises from failure to be explicit about two opposing impacts of remediation expenditures: (1) positive regional impacts of spending additional money in the region; and (2) negative regional impacts of the need to pay for the expenditures (and thus forego other expenditures in the region)...

The over- or under-prediction of risk in moderately contaminated sediments can have a large impact on the nature of applied management strategies since concentrations border on being toxic or not toxic. Project managers should give significant consideration as to how moderate levels of contaminants in native sediments and dredged material used for restoration will impact recovery of habitat. Total solid-phase (Ctotal ) and porewater (Cfree ) polycyclic aromatic hydrocarbons (PAHs) were quantified in native sediments and dredged material to determine if the predictions of risk from Ctotal are consistent with those based on Cfree ...

In 2011, the U.S. Environmental Protection Agency (USEPA) released a field-based method for estimating the extirpation of freshwater aquatic benthic invertebrates by ionic mixtures dominated by HCO3(-) , SO4(2-) , and Ca(2+) measured as specific conductivity (SC). The estimate of extirpation was SC at the 95(th) centile (XC95 ) of a weighted cumulative frequency distribution (CFD) of a genus or species over a range of SC. A CFD of XC95 values was used to predict the SC at which 5% of genera were likely to be extirpated...

Hydrodynamics and sediment transport are key physical processes contributing to habitat structure within the marine environment. Coastal development that results in the alteration of these processes (e.g., changing water flushing and/or sedimentation rates) can have detrimental impacts on sensitive systems. This is a current relevant issue in Qatar as its coastal regions continue to be developed, not only around the capital of Doha, but in many areas around this Arabian Gulf peninsula. The Northeastern Qatari coast is comprised of diverse and sensitive flora and fauna such as seagrass and macro-algae meadows, coral reefs/patches, turtles and dugongs that tolerate harsh environmental conditions...
