  title={Opinion: The water footprint of biofuel production in the USA},
  author={S. Powers and R. Dominguez-Faus and P. Alvarez},
  pages={255 - 260}
The US mandates for increased use of domestically produced biofuels will help to reduce the dependence on imported oil, yet it will necessitate the increased use of our earth and ecosystem services, our ‘natural capital’. Biofuels can be sustainably produced if we recognize the limits of our soil, water and air resources to provide these services. Many of the dedicated crops used for biofuels have a significant water footprint. That is, they consume water for growth and evapotranspiration, and… Expand
Regional water footprints of potential biofuel production in China
The water footprint results show that the feedstock growth is the most water footprint intensive process, while the biofuel conversion and transportation contribute little to total water footprints, while grey water footprint dominates the life-cycle water footprint for each type of the biofuels.

Renewable Fuel Standard: Potential Economic and Environmental Effects of U.S. Biofuel Policy
In the United States, we have come to depend on plentiful and inexpensive energy to support our economy and lifestyles. In recent years, many questions have been raised regarding the sustainabilityExpand
Hydrologic and water quality impacts of biofuel feedstock production in the Ohio River Basin
This study addresses the uncertainties related to potential changes in land use and management and associated impacts on hydrology and water quality resulting from increased production of biofuelExpand
Mapping cropland waterway buffers for switchgrass development in the eastern Great Plains, USA
Switchgrass (Panicum virgatum L.), a highly productive perennial grass, has been recommended as one potential source for cellulosic biofuel feedstocks. Previous studies indicate that plantingExpand
Energy's Water Demand: Trends, Vulnerabilities, and Management
The nation's energy choices embody many tradeoffs. Water use is one of those tradeoffs. The energy choices before Congress represent vastly different demands on domestic freshwater. The energyExpand
Using satellite vegetation and compound topographic indices to map highly erodible cropland buffers for cellulosic biofuel crop developments in eastern Nebraska, USA
Abstract Cultivating annual row crops in high topographic relief waterway buffers has negative environmental effects and can be environmentally unsustainable. Growing perennial grasses such asExpand
Region-Specific Indicators for Assessing the Sustainability of Biomass Utilisation in East Asia
This paper presents the findings of an expert working group of researchers from East Asian countries. The group was tasked with developing a theoretically sound and practically implementableExpand
Backgrounder: Major Environmental Criteria of Biofuel Sustainability


Water embodied in bioethanol in the United States.
The results indicate that bioethanol's water requirements can range from 5 to 2138 L per liter of ethanol depending on regional irrigation practices, and highlight the need to take regional specifics into account when implementing biofuel mandates. Expand
Corn-based ethanol production compromises goal of reducing nitrogen export by the Mississippi River

Examination of extreme mitigation options shows that expanding corn-based ethanol production would make the already difficult challenges of reducing nitrogen export to the Gulf of Mexico and the extent of hypoxia practically impossible without large shifts in food production and agricultural management.

Soil and Water Quality Implications Associated With Corn Stover Removal and Herbaceous Energy Crop Production in Iowa
The harvest of corn stover or herbaceous crops as feedstocks for bioenergy purposes has been shown to have significant benefits from energy and climate change perspectives. There is a potential,Expand
Nutrient loads to surface water from row crop production
Goals, Scope and BackgroundEutrophication and hypoxia, which are already serious environmental issues in the Midwestern region of the United States and the Gulf of Mexico, could worsen with anExpand
Nitrogen in crop production: An account of global flows
Human activities have roughly doubled the amount of reactive N that enters the element's biospheric cycle. Crop production is by far the single largest cause of this anthropogenic alteration.Expand
The water footprint of biofuels: a drink or drive issue?
The water consumption and agrochemical use during biofuel production could adversely impact both availability and quality of a precious resource.
Use of Monte Carlo analysis to characterize nitrogen fluxes in agroecosystems.
This paper employs Monte Carlo analysis (MCA) to model major nitrogen exports during crop production, focusing on corn-soybean rotations within the U.S. Corn Belt, and results indicate model distributions are in agreement with available measured emissions. Expand
Nitrogen sources and Gulf hypoxia: potential for environmental credit trading☆
A zone of hypoxic and anoxic waters has become a dominant feature of the northern Gulf of Mexico. Nitrogen draining into the Gulf from the Mississippi Basin has been identified as the primary sourceExpand
Impact of high crop prices on environmental quality: a case of Iowa and the Conservation Reserve Program.
Growing demand for corn due to the expansion of ethanol has increased concerns that environmentally sensitive lands retired from agricultural production into the Conservation Reserve Program (CRP)Expand
Cellulosic Biofuels—Got Gasoline?
The resulting hydrocarbon biofuels will be drop-in replacements for gasoline, diesel, and jet fuel; will give much higher gas mileage than ethanol; and will work in existing engines and distribution networks. Expand
