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

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对温室气体的影响。这将通过1)通过对现有土地利用数据进行地理空间分析来量化废弃农地的可用性，2)通过田间试验、作物普查和遥感数据的空间内插来确定这些土地上的潜在生物量产量，以及3)计算这些生物能源资源生命周期的温室气体净排放量。这项研究有可能极大地提高人们对气候变化惠益的认识和理解，这些惠益来自于利用废弃而不是目前使用的农地进行生物能源作物生产。将地理空间数据收集、模型和分析与温室气体生命周期评估结合起来，将带来方法上的进步。

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.
