Microplastic Pollution And Its Effects On Aquatic And Terrestrial Ecosystems, Anish Kumar Warrier Dr.

Technical Collection

Microplastics (MPs) are tiny pieces of plastics (less than 5 mm in size) that are ubiquitous in the environment. Their existence causes immediate threat to organisms of different sizes living in the water, sediments and soils affecting the food chain. Further, their presence in the marine realm can lead to a delay in the sequestration of carbon dioxide from the atmosphere into the oceans. The Environmental Microplastics Group at the Department of Civil Engineering, MIT, is primarily focused on the detection of microplastics and nanoplastics in the different environmental compartments, i.e., freshwater and marine water, sediments, soils, and biota such …

Water Quality Assessment For San Luis Obispo Creek And Stenner Creek, Jesse Stewart

Wagin Townsite Borefield: Review Of Aquifer Performance, Rockwater

Natural resources commissioned reports

The Wagin Borefield was established by the Department of Agriculture and Food, Western Australia in 2000-2007 to control groundwater levels in the town that had risen to critical levels as a result of increased recharge and runoff following the clearing of native vegetation for urban development and agriculture. Similar investigations were conducted as part of the Rural Towns Program and Rural Towns-Liquid Assets projects in 41 other wheatbelt towns, but none, except perhaps from Merredin, have been as comprehensively implemented, operated and monitored as Wagin.

The Wagin Borefield comprises 8 production bores, of which only 3 have been operated. To …

A Quantitative Application Of Diffusion Of Innovations For Modeling The Spread Of Conservation Behaviors, Matt Clark, Jeffrey Andrews, Vicken Hillis

Human-Environment Systems Research Center Faculty Publications and Presentations

The study of community-based conservation is challenged by a large number of important variables and nonlinear dynamics. This complexity has made quantitative and comparative analyses notoriously difficult. Here, we argue that analyzing the emergence and persistence of community-based conservation institutions as an emergent phenomenon of individual decision-making can yield important quantitative insights. We first review diffusion of innovations theory (DOI) and the broader field of cultural evolution. We then simulate data on community adoption of a conservation institution, contingent on feedbacks between individual behavior and environmental processes. We demonstrate that fitting these data to differential models of disease transmission, on …

The Consequential Role Of Aesthetics In Forest Fuels Reduction Propensities: Diverse Landowners’ Attitudes And Responses To Project Types, Risks, Costs, And Habitat Benefits, Robert G. Ribe, Max Nielsen-Pincus, Chris Enright, Bart R. Johnson, David Hulse

Environmental Science and Management Faculty Publications and Presentations

Private landowners in the southern Willamette Valley of Oregon, USA were surveyed. The survey queried probabilities of implementing specific fuels reduction projects in extensive areas of specific forest types on their property. The projects were described in relation to the beginning and target forest types, the actions required, costs, and long-term maintenance. Forest types were first rated for scenic beauty and informed levels of wildfire risk reduction, scarce habitat production, and associated property rights risks. Propensities to perform each fuels reduction project were then obtained. These were adversely affected by disbelief in heightened wildfire risks or climate change, higher project …

Coastal Squeeze, Climigration, And Equity Implications, Wie Yusuf

School of Public Service Faculty Publications

Summary: Coastal squeeze is impacting communities across the United States. Agricultural lands are affected by groundwater salt intrusion, habitats are lost due to limited space for species to migrate inland, natural capital and flood protection values are impacted by reduction in undeveloped land for natural ecosystems, infrastructure such as transportation are affected by flooding, and insurance companies are withdrawing from covering properties in coastal communities experiencing sea level rise and flooding. Resulting ‘climigration’ is occurring, for example, in Puerto Rico residents moving off the island, and subdivisions in North Carolina and Virginia being turned over to conservation. Lower-income communities are …

Mechanical and Aerospace Engineering Working Papers

Despite the climate commitments made by countries in the Paris Climate Agreement adopted in 2015, and reinforced during COP 21, world carbon emissions have increased in both 2021 and 2022. It is increasingly unlikely that the world can achieve the targeted 50% carbon reduction by 2030; the reduction approximately needed for reducing global temperature rise since the beginning of the industrial revolution to less than 1.5 deg. C. At the same time, the carbon intensive loads associated with bitcoin mining have grown, thereby contributing to growing worldwide carbon emissions. In this context, the role of cryptocurrency and particularly bitcoin is …

Stability Of Fishes Assemblage Structure Over A Lustrum In Coastal Wetlands Under Different Disturbances In An Industrial Zone Of The Central Gulf Of Mexico Coast, Carlos E. Cintra-Buenrostro, Alejandro Fierro-Cabo

School of Earth, Environmental, & Marine Sciences Faculty Publications

Shallow coastal wetlands within the territory of an industrial port in southern Tamaulipas, Mexico, were monitored seasonally over a lustrum, focusing on their fishes assemblage and water parameters. The purpose was to characterize these ecosystems that are affected by different disturbances of industrial origin, document changes, and assess potentially degrading terms as the affectations prevailed over the period of study. The wetlands are differentially affected by impacting land uses in their immediate surroundings, by crude oil leaks, and/or by diverse industrial wastewater discharges. Water parameters varied only slightly over time for most sites, and relative disparities among sites remained. The …

Development Of A Modified Screen Printed Electrode For The Determination Of Heavy Metals In Water Before And After Remediation With Food Grade Pectin And Citrofortunella Microcarpa Rinds, Shirley Palisoc, Natividad Michelle, Marissa Noel

Angelo King Institute for Economic and Business Studies (AKI)

The rapid increase in population, urbanization, and industrialization, along with inadequate water quality monitoring and wastewater management, contribute heavily to the pollution of water resources. Among the water contaminants of major concern, heavy metals are particularly considered as the most worrisome. Heavy metals tend to accumulate in the tissues of aquatic organisms (Ahmed et al., 2019; Rajeshkumar & Li, 2018; Tabrez et al., 2021) and thus increase in concentration upon moving higher up the food chain. This indicates that once humans ingest these organisms, they have a high risk of experiencing health problems as heavy metals are absorbed into their …

Climate Change Impacts On Groundwater In Mapc Communities, Jayne F. Knott, Paul Kirshen, Ellen Douglas

School for the Environment General Publications

Groundwater is important for human health and the environment but has often been overlooked in the development of climate change adaptation strategies. This is because groundwater is rarely visible, and because changes in groundwater levels are not as dramatic as extreme flooding events, coastal storms, and storm surge. The importance of groundwater for drinking water, natural resources, and streamflow is well documented. Groundwater levels are also important considerations in the design of pavements, underground infrastructure, foundations, on-site wastewater treatment systems, and in the remediation of hazardous waste disposal areas. Groundwater is especially important in the wet northeast, where groundwater levels …

Striving To Be Resilient: The Role Of Crop-Poultry Integrated System As A Climate Change Adaptation Strategy In Semiarid Eastern Kenya, Kelvin Mulungu, Daniel Kangogo

All Peer-Reviewed Publications

Climate change continues to pose significant challenges to food security and livelihoods of smallholder farmers specifically in semi-arid regions. One approach that holds prospects for climate risk management is climate-smart agriculture (CSA). CSA has concentrated on crop practices with little attention to livestock especially indigenous (village) chickens as a potential practice that can be combined with crop agriculture. This study considers the adoption of three CSA practices: improved maize seeds (IS), soil management (SM), indigenous chicken (IC) enterprise and their various combinations. Using survey data collected from 300 farming households in semiarid Kenya, we estimate the impact of integrated crop-poultry …

Harmonized Gap-Filled Datasets From 20 Urban Flux Tower Sites, Matthew Lipson, Sue Grimmond, Martin Best, Winston T. L. Chow

Research Collection College of Integrative Studies

A total of 20 urban neighbourhood-scale eddy covariance flux tower datasets are made openly available after being harmonized to create a 50 site–year collection with broad diversity in climate and urban surface characteristics. Variables needed as inputs for land surface models (incoming radiation, temperature, humidity, air pressure, wind and precipitation) are quality controlled, gap-filled and prepended with 10 years of reanalysis-derived local data, enabling an extended spin up to equilibrate models with local climate conditions. For both gap filling and spin up, ERA5 reanalysis meteorological data are bias corrected using tower-based observations, accounting for diurnal, seasonal and local urban effects …

In this context, agroecology is a game-changing approach that can provide the world’s growing population with nutritious, healthy affordable food, ensure fair incomes to farmers and halt and reverse the degradation of the natural environment. Here, we explore agroecological transition pathways …

Visual Report Of Cop26, Stéphanie Heckman

New England Journal of Public Policy

As a visual practitioner my job is to draw people’s thoughts, and in so doing, help people make sense of them. The visual summaries I create live during conferences aim to capture more than just the dry content, but also the dynamic, the mood and the unspoken. It is a tool more aligned with how our associative, sensory-fed brains work, for coping with the deluge of information that faces us these days. And it’s a tool that can help overcome language, learning and other barriers to access.

When I discovered in January 2020 that the next Conference of the Parties, …

Hydrogeologic Investigation Of A Covered Karst Terrain, Joseph Peter Honings

LSU Doctoral Dissertations

Increasing demand for water for agricultural use within the Dougherty Plain of the Southeastern United States has depleted surface water bodies. In karstic landscapes, such as the Dougherty Plain in southwest Georgia where the linkages between surface and ground waters are close, there is a need to understand the physical characteristics of the subsurface that allow these close linkages. Having a better understanding of the subsurface characteristics will aid numerical modeling efforts that underpin policy decisions and economic analyses. Two common features on this karstic landscape are draws and geographically isolated wetlands. Using LiDAR, aerial imagery, and ground-penetrating radar, this …
