概括
全球灾难可能会破坏燃料贸易,影响粮食安全. 新西兰需要大量的土地来种植燃油效率高的小麦和甘露作物,以维持没有进口的农业.
科学领域:
- 农业科学 农业科学
- 能源安全 能源安全
- 生物燃料是一种生物燃料.
背景情况:
- 全球灾难可能会扰乱液体燃料贸易,威胁粮食安全,特别是对依赖进口的国家.
- 完全依赖进口精炼燃料的岛屿国家面临极大的脆弱性.
研究的目的:
- 为了估计维持新西兰人口所需的农业用地和生物燃料数量,没有贸易.
- 评估不同作物的燃油效率,以满足国家粮食供应.
主要方法:
- 在贸易中断情景下分析新西兰农业需求的案例研究.
- 对小麦,土豆和乳制品生产的柴油燃料需求的计算.
- 为粮食和生物燃料种植小麦和甘露的土地面积估计.
主要成果:
- 储存的柴油储备在没有贸易的情况下迅速 (几周到几个月) 耗尽.
- 小麦种植比土豆 (每年1230万升) 或乳制品 (每年3870万升) 更省油 (每年540万升).
- 足够的小麦需要24%的现有谷物土地;生物燃料原料 (canola) 需要额外的1%-7%.
结论:
- 对于农业燃料需求而言,对甘生物柴油/可再生柴油炼油厂的投资至关重要.
- 在灾难发生前,炼油和大麻作物的扩张可以提高燃料的弹性.
- 生物柴油生产也可以实现减排目标,因此需要进一步分析.

Adaptations that Reduce Water Loss
25.6K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Overview of Metabolism
30.1K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Bioremediation
18.3K
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.

The Calvin Benson Cycle
4.5K
Ribulose 1,5- bisphosphate carboxylase/oxygenase (RuBisCo) is a critical enzyme that catalyzes carbon dioxide assimilation during photosynthesis. However, it is an inefficient enzyme, having an extremely slow catalytic rate. A typical enzyme can process about a thousand molecules per second; however, RuBisCo fixes only around three-carbon dioxides per second. Photosynthetic cells compensate for this slow rate by synthesizing very high amounts of RuBisCo, making it the most abundant single...

What is Climate?
18.5K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.
