中西部的农田是食物和燃料的来源，也是生物多样性的来源。这也是进入密西西比河和墨西哥湾的过量营养物质的一个原因。为了应对生物地球化学循环和生态系统功能的不可持续变化，涉及社会科学、自然科学和工程学的多学科方法往往是有效的。考虑到第二代生物燃料的潜力，并利用根深蒂固的多年生生物能源作物能够在贫瘠的土壤中茁壮成长，我们展示了对伊利诺伊州行作物景观中种植柳枝菊的影响的综合社会环境分析。在这项研究中，我们使用土壤水分评估工具，结合对伊利诺伊州朱砂盆地的经济分析，对中西部玉米带流域的土地利用情景进行建模，其中包括柳枝草作为生物燃料作物。我们估计了替代生物能源格局下生态系统服务的价值，包括商品和生物能源作物、生物地球化学变化和娱乐服务。据估计，生物能源作物每年减少硝酸盐和沉积物的价值分别为3800万至9700万美元和1.6万至19.7万美元。根据最初的作物轮作模式，二氧化碳减排的年价值从180万美元到610万美元不等。野生动物观赏、水上娱乐和野鸡狩猎的估计年平均价值分别为124万美元、17万美元和30万美元。据我们所知，这项研究是使用基于过程的模型全面量化生态系统服务并估计其在替代生物能源环境中的价值的第一次努力。我们产生的信息可以帮助理解边际土地的生物质生产潜力和景观在不同空间尺度上的总经济价值。该框架有助于培育替代生物能源景观，在食品、能源和保护关系中发挥协同作用。
Agricultural land in the Midwest is a source of food and fuel, as well as biodiversity. It is also a cause of excess nutrients that make their way to the Mississippi River and the Gulf of Mexico. To address unsustainable changes to biogeochemical cycles and ecosystem functions, a multidisciplinary approach involving social science, natural science, and engineering is often effective. Given the potential of second‐generation biofuels, and capitalizing on the deep‐rooted perennial bioenergy crops capable of thriving in poor soils, we demonstrated an integrated socio‐environmental analysis of the impacts of growing switchgrass within row‐crop landscapes in Illinois. In this study, we model land use scenarios that incorporate switchgrass as a biofuel crop in a Midwest corn‐belt watershed using the Soil Water Assessment Tool coupled with an economic analysis for the Vermilion Basin in Illinois. We estimated the values of ecosystem services under an alternative bioenergy landscape, including commodity and bioenergy crops, changes in biogeochemistry, and recreational services. The estimated annual values of nitrate and sediment reduction attributed to bioenergy crops range from $38 million to $97 million and $16,000 to $197,000, respectively. The annual value of carbon dioxide emission reduction ranges from $1.8 million to $6.1 million based on the initial crop rotation pattern. Estimated average annual values for wildlife viewing, water‐based recreation, and pheasant hunting are $1.24 million, $0.17 million, and $0.3 million, respectively. To our knowledge, this study represents the first effort to comprehensively quantify ecosystem services using a process‐based model, and estimate their value in an alternative bioenergy landscape. The information we generate could aid in understanding the potential for biomass production from marginal land and the total economic value of the landscape at various spatial scales. The framework is useful in fostering alternative bioenergy landscapes with synergies in a food, energy, and conservation nexus.
