Sensory, Nutrition, Education Promoting Locally Grown Fruits and Vegetables Among Western Massachusetts Head Start Children

Increasing the consumption of fruits and vegetables in young children and reducing childhood obesity is a key national nutrition goal. This project will examine use of  a sensory-affective, comprehensive approach to promote early childhood consumption of locally grown fresh fruits and vegetables. The direct correlation between fruit and vegetable consumption and lowering of obesity is yet to be established in this life-stage. However, the prevalence of obesity has more than doubled among children ages two to five (5.0% to 12.4%).

Strategies to Evaluate and Mitigate Ozone Impacts on the Structure and Function of Vegetation

There is uncertainty about the effects of future climate on agricultural crop plants. Alfalfa is a crop that is used to provide feed for animals leading to meat production. This research will include experiments under controlled conditions that will allow prediction of how alfalfa plants will respond to future elevated CO2 (800ppm) and elevated ozone (O3) (80ppb). How these elevations affect plant growth and the nutritional value of the plants will be determined.

The Role of the Massachusetts Expanded Food and Nutrition Program in Promoting Food Security Among SNAP Participants and SNAP Eligibles

Food insecurity, or not having access at all times to enough food for an active and healthy lifestyle, has been linked to a number of poor health outcomes, including low micronutrient intake, poor academic scores in children and adolescents, and overweight and obesity in adults. The federally-funded Expanded Food and Nutrition Education Program (EFNEP) program provides nutrition education to Supplemental Nutrition Assistance Program (SNAP) recipients and eligibles and other low-income families.

Theoretical, experimental, valuation and empirical issues in the design of environmental and natural resource policies

While most economists tout the benefits of using incentive-based policies (like emission taxes, emissions markets, and individual transferable quotas), many conceptual details concerning implementation and management of these policies have not been addressed. Recent research suggests that commonly-held notions of efficient incentive-based policies need to be modified to account for the costs of enforcing these policies.

Use of Bioactive Food Components to Modulate Vitamin D Receptor Function

It is especially important to pursue research on bioactive food components at this time because it has the potential of identifying a novel avenue for targeting dietary prevention strategies to help alleviate the growing medical costs and societal burden related to diet-based problems in the area of obesity and chronic disease. The current project will investigate the effects of a bioactive food component called sulforaphane, which is found in broccoli and other cruciferous vegetables, on basic cellular functions using cell culture and animal (mice) models.

Whole Farm Dairy and Beef Systems: Gaseous Emissions, Pmanagement, Organic Production, and Pasture Based Production

Livestock farms face a number of environmental concerns including both water and air quality issues. Stakeholders and regulators agree that attaining the dual goals of profitability and environmental accountability are major challenges facing animal agriculture. Under current economic conditions with increasing input costs and stagnant or decreasing product prices, many farms are struggling to survive. The additional costs of mitigating environmental impacts may accelerate farm exit.

Protecting water security in watershed systems: uncertainty in decision making

Providing steady supplies of water, safe drinking water, and sustaining diverse, healthy aquatic ecosystems are objectives of watershed managers. Disruptions in water supplies and quality can have serious economic and ecological impacts. Addressing water security is becoming an important aspect of watershed management that can increase the sustainability and resiliency of watershed systems. Therefore the question arises: How can water managers plan for and maintain secure water supplies under uncertain conditions?

Quantifying Growth and Establishment of Trees Planted in Residential Settings

The value of trees planted in residential settings has been well documented (Shroeder et al. 2006; McPherson et al. 2007), but value is only realized if trees grow to maturity. The same settings where trees provide benefits, however, present challenging and even severe growing conditions that may thwart survival and growth (Jutras et al. 2010). Empirical data to describe the survival and growth of such trees are limited, and most of the work has considered trees growing in field plots rather than actual residential settings (Watson et al. 1986; Morgenroth 2011).

Red Spruce-Balsam Fir forests in Massachusetts: forest dynamics in natural communities vulnerable to climate change

It has been hypothesized that climate change will cause plant species ranges to shift northward with plants at the south end of ranges declining in vigor and growth rate. The purpose of this research is to test this hypothesis for red spruce and balsam fir along the southern end of the continuous distribution of these species, in Massachusetts. By measuring the growth patterns of these trees, we can determine if the southern end of the range has been declining, relative to more northern stands of these species.

Soil-Based Use of Residuals, Wastewater and Reclaimed Water

With the rapid development and wide application of nanotechnology, the introduction of manufactured nanomaterials into both solid and liquid wastes (and to the environment) is inevitable through production, use, and disposal. It has been reported in 2008 that nano-TiO2 is leached out of house facades into receiving surface waters. Currently, there are over 800 products on the market containing nanomaterials such as lotions, sunscreens, paints, and socks. This research will determine the environmental behavior and process of several types of manufactured nanomaterials.
