“…Agriculture is responsible for the largest contribution of non-point nitrogen source pollution in Germany [12,13]. For the continued cultivation of bioenergy crops, feedstock production will require increased fertiliser input, which may have environmental implications [14,15]. For example, maize requires more fertilisers than other crops [16], even though it can use the mineral and organic fertiliser effectively [17].…”

“…For instance, the impact of conservation tillage and intercropping buffer strips was quantified in two watersheds in central Iowa in the USA [24]. In addition, the SWAT model was used to predict the possible long-term effects of large scale bioenergy cropping system expansion on soil and water quality using different land use and crop rotation scenarios [14,15,[25][26][27]. Among these models, the HYdrological Predictions for the Environment (HYPE) model is a spatially semi-distributed and process-based hydrological water quality model [28].…”

Background: Understanding the response of nitrogen fluxes to changes in land use and agricultural practices is crucial for improving the instream water quality prediction. In central Germany, the expansion of bioenergy crops during the last decade led to an increase in fertiliser application rates. The purpose of this study is to investigate the effect of agricultural management changes on the stream nitrogen load of a drinking water reservoir catchment (Weida, 99.5 km

“…Although significant research has been accomplished on impacts of first generation biofuels related to land use [4,11], water consumption [12,13], water quality [14,15], environmental impacts of 2nd generation biofuels like switchgrass has been studied less. De La Torre Ugarte et al [16] examined the effects of two cellulosic ethanol production expansion scenarios on agriculture, water demand, and water quality in the U.S. while studies by Secchi et al [5] and Wu et al [17] looked at water quality implications of switchgrass and corn.…”

Impact of climate change on the water resources of the United States exposes the vulnerability of feedstock-specific mandated fuel targets to extreme weather conditions that could become more frequent and intensify in the future. Consequently, a sustainable biofuel policy should consider: (a) how climate change would alter both water supply and demand; and (b) in turn, how related changes in water availability will impact the production of biofuel crops; and (c) the environmental implications of large scale biofuel productions. Understanding the role of biofuels in the water cycle is the key to understanding many of the environmental impacts of biofuels. Therefore, the focus of this study is to model the rarely explored interactions between land use, climate change, water resources and the environment in future biofuel production systems. Results from this study will help explore the impacts of the US biofuel policy and climate change on water and agricultural resources. We used the Soil and Water Assessment Tool (SWAT) to analyze the water quantity and quality consequences of land use and land management related changes in cropping conditions (e.g., more use of marginal lands, greater residue harvest, increased yields), plus management practices due to biofuel crops to meet the Renewable Fuel Standard target on water quality and quantity.

“…Future production under the RFS2 targets will also be met through cellulosic biofuel from lignocellulosic crops (i.e. switchgrass and/or miscanthus) Le, Kumar & Drewry 2011), possibly grown on CRP lands ( Figure 1 [c]) Love & Nejadhashemi 2011;. The use of CRP lands for large-scale lignocellulosic crop production has been proposed in the medium-to longterm ).…”

“…Runoff volume, and sediment (from soil erosion), nitrogen and phosphorous loads in streams have been the most common indicators used to date to evaluate impacts on water quantity and quality due to bioenergy feedstock production Love & Nejadhashemi 2011;Efroymson et al 2013). Past hydrological studies have affirmed that land use changes from native vegetation to other human-induced land uses increase: the overland flow of storm runoff; suspended sediment; and nutrient exports in surface water (Williams & Melack 1997;Brodie & Mitchell 2005).…”

Environmental Consequences of Land use Changes for Bioenergy Crop Production at a Regional Scale

Sustainability has become a focus of global bioenergy (especially biofuel) policy and research over the past few years. Due to the rapid expansion of demand for global bioenergy and increased sustainability requirements, land use change associated with bioenergy crops (hereafter referred to as 'bioenergy-driven land use change') has emerged as an important research topic. The use of degraded land, marginal and abandoned agricultural lands (hereafter referred to as 'underutilised agricultural land') has been proposed for non-food and lignocellulosic crop production. However, the implications and consequences of the use of these lands remain highly uncertain. This was a study to evaluate the regional environmental effects of the use of underutilised agricultural land for bioenergy production using a spatial modelling approach and land use change scenarios in a case study region-the Burnett River catchment, Australia.The aim of this research was to evaluate whether land use change scenarios that involve bioenergy crop production on underutilised agricultural land can enhance regional-scale environmental outcomes when compared with current land uses, and to provide recommendations and suggestions for future land use options. The scenarios assessed in this research, including the selection of bioenergy crops (and the associated management practices) and land use change pathways, were developed to minimise potential environmental impacts. In line with four research objectives based on the aim, a review of past studies relating to bioenergy-driven land use changes was conducted to better understand their dynamics and their effects both in the past, and in future projections (Objective 1, Chapter 2). A spatially explicit evaluation framework was developed to evaluate regional scale environmental consequences associated with land use changes (Objective 2, Chapter 3). The evaluation framework focused on the issues of water quantity and quality (and soil erosion), and terrestrial biodiversity, the impacts of which are commonly experienced regardless of geographical region. It was tested in a case study region in subtropical Queensland, Australia (Objective 3, Chapter 5), and then applied to six bioenergy-driven land use change scenarios to quantify the impacts and compare the results with a baseline (2005/06) and with other scenarios (Objective 4, Chapter 6). The findings from the evaluation were synthesised as recommendations for future bioenergy sustainability research community and policy, and also as a basis for decision making concerning sustainable land use options for future bioenergy production (Chapter 6 and 7).The results of the land use change scenario evaluation indicated that bioenergy crop scenarios could benefit regional environmental quality in the case study region only when:(i) open grazing areas (pastures) were used as the plantation site, ii (ii) native woody perennial bioenergy crops were used (e.g. Pongamia [Millettia pinnata] or Short Rotation Coppice [SRC] eucalyptus species), and (iii) t...
