Pollinator decline: US Agro-Socio-Economic Impacts and Responses
Published in Journal of Natural & Environmental Sciences, 2013
In this paper we present a holistic evaluation of impacts and responses to pollinator decline in the US in an effort to summarize the spatial and temporal state of US pollinators, to review possible pressures and drivers of national pollinator decline, to examine the agro-socio-economic impact of the state of pollinators, and to provide a comprehensive insight into associated problems and solutions.

Impacts of biofuel-based land-use change on water quality and sustainability in a Kansas watershed
Published in Agricultural Water Management, 2016
In this paper water quality and sustainability indicators are used to evaluate the impacts of land-use change to increase corn and grain sorghum acreage for biofuel productionin the Perry Lake watershed in northeast Kansas.
