概括

与玉米乙醇相比,大豆生物柴油生产显著增加了土地转化,影响了保护保护区计划的英. 量化这些影响对于未来美国生物燃料政策至关重要.

科学领域:

农业经济学农业经济学
环境科学环境科学
土地使用政策土地使用政策

背景情况:

美国大豆生物柴油产量正在增长,这给土地利用带来了潜在的挑战.
由于土地供应不弹性,现有的土地需求可能会受到生物燃料生产增加的非线性影响.

研究的目的:

量化美国大豆生物柴油扩张对土地利用的影响.
为了隔离生物柴油对转化保护储备计划 (CRP) 面积和非耕地为作物生产的影响.
为未来关于生物燃料生产的政策提供信息.

主要方法:

应用一个多时期的部分平衡经济模型 (BEPAM).
经过验证的反事实场景的分析 (没有生物燃料政策,只有玉米乙醇任务).
2007-2018年期间土地使用变化的估计.

主要成果:

生物柴油土地利用变化强度在2018年远高于玉米乙醇 (0.78-1.5万英/十亿加),而不是玉米乙醇 (0.57-0.75万英/十亿加).
土地使用变化弹性对于生物柴油来说比玉米乙醇更不弹性.
农田扩张在爱荷华州,明尼苏达州,北达科他州,堪萨斯州,密歇根州和密西西比州最为显著.

结论:

豆生物柴油的扩张推动了比玉米乙醇更大的土地转化.
关于生物燃料扩张的政策决策必须考虑大豆生物柴油对土地利用的影响不成比例.
了解土地租金弹性是管理生物燃料引起的土地使用变化的关键.

Fates of Pyruvate

Fates of Pyruvate

Pyruvate is the end product of glycolysis, where glucose is oxidized to pyruvate, simultaneously reducing NAD+ to NADH. Two molecules of ATP are also produced by substrate-level phosphorylation.
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
