Clark University doctoral candidate Melishia Santiago grew up with palm trees and warm weather near sunny Atlantic beaches in Florida and Puerto Rico before coming north to Massachusetts for college. Now, she spends her time thinking about ice, specifically how climate change impacts sea-ice extent in the western Arctic Ocean. More »

Navigating Tradeoffs between Pest Suppression and Pollinator Conservation

bee

Originally introduced in the mid-1990s, neonicotinoid insecticides ('neonics') experienced an exponential rise in use over the past two decades and are now the most widely used insecticides in the world. Unfortunately, the attributes that make neonics versatile and powerful pest management tools also make non-targeted insects vulnerable to their effects. Specifically, neonics have been implicated as a factor in sudden die-offs of managed honeybee hives and long term declines in native bee populations. Thus, farmers growing pollinator-dependent crops, which represents a large fraction of all fruits and vegetables, are confronted with a potential tradeoff between two competing aspects of crop production: effective pest suppression and successful pollination. Marsh Institute Assistant Director Dana Bauer and collaborators from Purdue University, Michigan State University, Ohio State University, and the University of New Hampshire received $3.6 million from the US Department of Agriculture for a 5-year interdisciplinary project that will develop holistic pest-pollinator joint management regimes that are effective, profitable, and sustainable. The project will: identify insecticide management strategies that simultaneously optimize pest suppression while minimizing non-target exposure to pollinators; determine the consequences of neonic exposure for honey and wild bee health; and assess the ecological and socioeconomic tradeoffs among pollinators, pests, crop yield, and farm profitability resulting from alternative pest management regimes. Bauer will lead the economic analysis of grower preferences, profitability, and decision-making.

Generating Knowledge for Climate Information Services Design and Implementation

Climate information services (CIS) involve the production and use of climate knowledge in climate-smart decisions, planning, and policy-making. Easily accessible, timely, and relevant scientific information can help society cope with current climate variability and limit the economic and social damage caused by climate-related disturbances. A group of Marsh Institute researchers, including Edward Carr, Director of IDCE, HURDL (Humanitarian Response and Development Lab) Research Scientist Sheila Onzere, and Marsh Research Scientist Robert Goble, was awarded just under $400k in funding from USAID and Mercy Corps to explore ways to increase the efficiency and effectiveness of future investments in Climate Information Services (CIS) delivery, and ultimately increase the number of users of CIS who will benefit through livelihood practices. Using literature reviews, analyses of existing CIS systems, and a pilot evaluation program using the HURDL Livelihoods as Intimate Government (LIG) approach, the project team seeks to (1) increase understanding of, and access to, knowledge on the effectiveness of current CIS programming, (2) expand the current understanding of how CIS systems function in the context of broader social, cultural, and institutional systems within which they operate, (3) increase evidence on the degree of effectiveness of CIS on livelihoods, and (4) escalate dissemination and uptake of new knowledge.

Reducing Gang Violence in Worcester's Eastside Neighborhoods

Worcester, Massachusetts--the second largest city in New England with a population of 183,000--exhibits many established risk factors for youth and gang violence. Laurie Ross, Professor of IDCE and Marsh Institute researcher, received new grant funding from the City of Worcester to develop and manage a data tracking system and share best-practice research that will help reduce gang violence and prevent gang initiation among high-risk youth ages 12-17 in Worcester's Eastside neighborhoods. By focusing on Worcester's Eastside neighborhoods and on youth ages 12-17, this project addresses a major geographical, age, and programmatic gap identified in Worcester's Youth Violence Prevention Initiative--which was the result of a comprehensive community gang assessment and citywide strategic planning process. The project will bolster Worcester's Comprehensive Gang Model to direct outreach workers and case management to youth who live on the city's Eastside.

Examining the Homogenization of American Residential Landscapes

An apparent, but untested result of changes to the urban landscape is the homogenization of cities, such that neighborhoods in very different parts of the country increasingly exhibit similar patterns in their road systems, residential lots, commercial sites, and aquatic areas; that is, cities have now become more similar to each other than to the native ecosystems that they replaced. Marsh Institute researcher and Associate Professor of Geography, Rinku Roy Chowdhury, with collaborators at City University of New York and eight other institutions, received funding from the National Science Foundation to examine the homogenization of American residential landscapes and investigate factors that contribute to stability or changes in those landscapes. The aim is to determine how factors that effect change--such as shifts in human demographics, desires for biodiversity and water conservation, regulations that govern water use and quality, and dispersal of organisms--will interact with factors that contribute to stability such as social norms, property values, neighborhood and city covenants and laws, and commercial interests. The project will determine ecological implications of alternative futures for the assembly of ecological communities, ecosystem function, and responses to environmental change and disturbance at parcel (ecosystem), landscape (city), regional (Metropolitan Statistical Area), and continental scales. Analyses will take place across six U.S. cities (Boston, Baltimore, Miami, Minneapolis-St. Paul, Phoenix, and Los Angeles).

Facilitating Broader Use of NASA's Carbon Monitoring System

From its inception, the NASA Carbon Monitoring System (CMS) has largely been organized around two activities: observation-based mapping of biomass and model-based estimation of carbon flux. Although there has been significant progress in both biomass and flux activities at various scales, several challenges hinder the use of biomass products to inform flux modeling. Challenges include biomass maps that are often static or local scale, uncertainties that are difficult to render and incorporate into models, and map products that are not designed with the needs and format standards of modelers in mind. To help address these challenges, Marsh researcher and Associate Professor of Geography, Chris Williams, along with colleagues at Oregon State University, received funding from NASA to develop new tools that will facilitate broader use of CMS data products by: (a) converting static maps of above ground biomass and land cover to dynamic yearly maps, and (b) collaborating with modelers and stakeholders to build a convenient, easy-to-use interface to the dynamic map results. This set of tools will add significant value to the CMS program by thoughtfully and deliberately connecting the results from various disparate projects to each other and to modeling and accounting frameworks that provide a more integrated view of carbon dynamics.

Ecosystems Slow the Rate of Rising CO2 Concentration

Landscape of trees in Australia

The rate at which carbon dioxide is accumulating in the atmosphere has plateaued in recent years because terrestrial ecosystems are grabbing more carbon from the air than in previous decades, according to a new multi-institutional study published online in the journal Nature Communications. Christopher A. Williams, associate professor of geography at Clark University, is a co-author on the article. More »

Estimating the Value of Water Quality Improvements

Johnston

The recent drinking water crisis in Flint, Michigan is an extreme example of what can go wrong when people do not understand the value of clean waterways. It reinforces the need to better understand the costs and benefits of protecting the environment, including the quality of water in rivers and streams. Yet water quality provides many benefits beyond those associated with drinking water; it also provides social benefits through effects on wildlife, recreation, aesthetics, and other outcomes that affect people's lives. As part of a newly awarded $800,000 grant from the U.S. Environmental Protection Agency (EPA), environmental economist and Marsh Institute Director Robert Johnston is leading an interdisciplinary team of researchers to develop new methods to quantify the value of water quality improvements to the public, focusing on rivers and streams in the Northeast US. The award is part of a US EPA program that seeks to improve our understanding of the value of water quality improvements across the US, and is one of only six awards made nationwide. More »
