Water Quality Effects Of Cellulosic Biofuel Crops Grown On Marginal Land, Ruoyu Wang Jul 2014

Water Quality Effects Of Cellulosic Biofuel Crops Grown On Marginal Land, Ruoyu Wang

Ruoyu Wang

Since Congress' Energy Independence and Security Act of 2007, there has been increasing interest
in the ability to reach the cellulosic renewable fuel goal of 60.5 billion liters. Cellulosic biofuel crops include
sorghum, switchgrass, Miscanthus, woody crops, and crop residue, among others. Because of concern about
food production on existing highly productive agricultural lands, there is an interest regarding biofuel crop
production on marginal lands. Second generation biofuels, such as perennial grasses and woody plants,
provide an alternative to traditional crops; however, their effects on water quality are not well studied when
grown on marginal lands. Because grasses and woody …

Responses Of Hydrological Processes And Water Quality To Land Use/Cover (Lulc) And Climate Change In A Coastal Watershed, Ruoyu Wang Jan 2014

Responses Of Hydrological Processes And Water Quality To Land Use/Cover (Lulc) And Climate Change In A Coastal Watershed, Ruoyu Wang

Ruoyu Wang

Land use/cover (LULC) and climate change are two main factors affecting watershed hydrology and, in turn, influencing water quality. In this paper, the potential changes in flow, Total Suspended Solid (TSS) and nutrient (nitrogen and phosphorous) loadings were investigated under climate, LULC and combined change scenarios in the Wolf Bay watershed in coastal Alabama, USA. Four Global Circulation Models (GCMs) under three Special Report Emission Scenarios (SRES) of greenhouse gas were used to demonstrate the future climate change (2016-2040). Three projected LULC maps (2030) were employed to reflect different extents of urbanization in future. The individual, combined and synergistic impacts …

Elevated level of fluoride (F−) in drinking water is a well-recognized risk factor of dental fluorosis (DF). While considering optimization of region-specific standards for F−, it is reasonable, however, to consider how local diet, water sourcing practices, and non-F− elements in water may be related to health outcomes. In this study, we hypothesized that non-F− elements in groundwater and lifestyle and demographic characteristics may be independent predictors or modifiers of the effects of F− on teeth. Dental examinations were conducted among 1094 inhabitants from 399 randomly selected households of 20 rural communities of …

On Target For People And Planet: Setting And Achieving Water-Related Sustainable Development Goals, Julie Van Der Bliek, Peter G. Mccornick, James Clarke Jan 2014

On Target For People And Planet: Setting And Achieving Water-Related Sustainable Development Goals, Julie Van Der Bliek, Peter G. Mccornick, James Clarke

Daugherty Water for Food Global Institute: Faculty Publications

Our specific focus in this book is on securing water for sustainable food production. This links to sustainable water resources management, delivering on the water supply and sanitation requirements and provisioning water for energy and the urban sector. A specific intent is to ensure that the realities in low- and middle-income countries in Africa and Asia are recognized and to provide practical pathways to change that fit these realities and the aspirations of those countries. This will help to prepare for the next step in the SDG [sustainable development goals] process: devolving the SDGs to the national level. It will …
