Qingyu Feng. M.S.A.B.E., Purdue University, December 2013. Biomass Production and Hydrological/Water Quality Impacts of Perennial Crop Production on Marginal Land. Major Professor: Indrajeet Chaubey. Marginal land has been proposed to be a viable choice for biomass production to meet the biofuel development goal set by Energy Independence and Security Act (EISA). However, very little informatio...

It has been widely accepted that there is a close relationship between the land use type and water quality. There have been some researches on this relationship from the perspective of the spatial configuration of land use in recent years. This study aims to analyze the influence of various land use types on the water quality within the Chaohu Lake Basin based on the water quality monitoring da...

The Mishna in Tractate Gittin discusses land qualities, in a context where land is used to settle monetary obligations. The law is that land of different qualities must be used to pay claimants in different situations; in particular, claimants pursuant to a tort case have the right to have their claim paid with land of the best quality. Creditors have the right to be paid with land of medium qu...

This paper analyzes the effect of landowner risk preferences and land quality on the optimal mix of vertically integrated production and contracted production of an energy crop in a region characterized by heterogeneity in landowners’ risk preferences and land quality and with riskiness of returns from both energy crop and conventional crop production. We examine the determinants of the decisio...

This study examines the relationships between land cover change and water quality change in three urbanizing watersheds in the Pacific Northwest region of the United States: Burnt Bridge Creek, Salmon Creek, and the Tualatin River. All three watersheds have had many of their water quality parameters exceeding Total Maximum Daily Loads as required by their state’s environmental agencies in the p...

Changes in surface land use may threaten groundwater quality and ecosystem integrity, particularly in shallow aquifers where links between groundwater and surface activities are most intimate. In this study we examine the response of groundwater ecosystem to agricultural land uses in the shallow alluvial aquifer of the Gwydir River valley, New South Wales, Australia. We compared groundwater qua...

Intraurban land-use change and factors affecting it are critical subjects in land-use planning. If unplanned, such changes can reduce the quality of life and spatial justice and ultimately lead to urban unsustainability. This paper aims to identify factors influencing unsustainable land-use change and analyze the intensity of such changes based on those factors. The artificial neural network an...
