The economy of northwest Arkansas, including the Lincoln Lake watershed (a sub-watershed of the Illinois River), relies greatly upon livestock and poultry production. The supply of production by-products is increasingly under scrutiny as one of the potential sources of water pollution in the...

Phosphorus runoff has generated water quality degradation, spawning legislative and regularity actions in several watersheds in Northwest Arkansas. Best management practices (BMPs) can be viable alternatives in dealing with nutrient excess. The profitability of several BMPs deemed effective in...

Preliminary results of a survey of agricultural and non-agricultural stakeholders in the Lincoln Lake Watershed suggests discrepancies exists in different groups perceptions of water quality, the sources of water pollution, and the roles of local, county, state and federal officials in meeting...

This poster describes the integration of life cycle costing capabilities into a life cycle assessment model of greenhouse gas emissions for US swine production. Combining both tools allows for a sustainable analysis of a process to identify potential production practices which are...

The market for conservation easements provides a way to ensure the continued existence of open space amenities where rural communities face development pressure. The object of this research is to identify factors affecting land trust agents’ preferences for conservation easements and to...

This study examines the trade-off between agricultural production and groundwater contamination potential for ten potential herbicide cancellations. Theoretical and empirical models are developed for estimating losses in consumer and producer benefits in the agricultural commodity market and...

This study compares subsurface drip irrigation and sprinkler irrigation with respect to expected returns, aquifer life, nutrient utilization and accumulation in the production of irrigated corn using swine effluent and fresh groundwater from a depleting aquifer in the Oklahoma Panhandle. Most of...

Recent studies have suggested that green technologies may be a cost effective way to manage urban runoff. Literature has also suggests that there needs to be a greater empirical basis to estimate the benefits associated with social values associated with urban trees; we therefore estimate...
