CAREER: Land Use Analysis for Sustainable Bioenergy Production on Marginal Lands

0955141坎贝尔将研究美国和巴西利用废弃农田种植生物能源作物的温室气体影响。这将通过以下方式实现：1）通过对现有土地使用数据进行地理空间分析，量化废弃农田的可用性; 2）通过田间试验、作物普查和遥感数据的空间插值，确定这些土地上的潜在生物量产量; 3）计算这些生物能源资源生命周期的温室气体净排放量。 这项研究有可能大大提高对气候变化好处的认识和理解，这些好处来自于使用废弃的而不是目前使用的农业土地进行生物能源作物生产。 将地理空间数据收集、模型和分析与生命周期温室气体评估相结合，将在方法上取得进展。

0955141CampbellThe GHG implications of using abandoned agricultural lands to grow bioenergy crops in both the U.S. and Brazil will be studied. This will be achieved by 1) quantifying the availability of abandoned agricultural lands through geospatial analysis of existing land use data, 2) determining the potential biomass yields on these lands through spatial interpolation of field trial, crop census and remote sensing data, and 3) calculating the net GHG emissions from the life cycles of these bioenergy resources. This research has the potential to significantly advance knowledge and understanding of the climate change benefits that would come from using abandoned rather then currently used agricultural land for bioenergy crop production. Methodological advancements will result from coupling geospatial data collection, models and analysis with life cycle GHG assessments.
