概括
本指南提供了一个框架,将广泛的环境保护目标转化为环境风险评估 (ERA) 的具体,可衡量的目标. 它确保生物多样性和生态系统服务被考虑为更有效的保护战略.
科学领域:
- 环境科学环境科学
- 生态生态学 生态生态学
- 风险评估 风险评估 风险评估
背景情况:
- 环境保护依赖于保护生物多样性和保持健康的生态系统.
- 目前的立法保护目标往往太一般了,无法用于实际的环境风险评估 (ERA).
- 欧洲食品安全局 (EFSA) 要求其ERAs具有特定的保护目标 (SPG).
研究的目的:
- 提出将一般保护目标转化为具体保护目标 (SPG) 的框架.
- 为了使一般的保护目标在EFSA ERAs的所有领域都能运行.
- 确保生物多样性和生态系统服务融入ERA过程.
主要方法:
- 该框架涉及三个连续步骤:确定相关的生态系统服务,确定服务提供单位 (SPU),并指定SPU的保护级别/参数.
- 保护水平是使用五个相互关联的维度来定义的:生态实体,属性,大小,时间尺度和影响的空间尺度.
- 该过程强调与风险管理人员进行对话,以确定受监管产品的可容忍影响.
主要成果:
- 建议采用结构化,三步的方法来实现保护目标.
- 该框架将生物多样性和生态系统服务纳入ERA.
- 为了提高透明度和一致性,提供了为选择的保护级别提供理由的考虑因素.
结论:
- 拟议的框架允许将广泛的环境目标转化为ERA的具体,可行的目标.
- 这种方法支持EFSA对环境风险的评估更加一致和透明.
- 整合生态系统服务和生物多样性考虑,加强了环境保护措施.

What is Biodiversity?
27.9K
Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.

Threats to Biodiversity
21.7K
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...

What is Conservation Biology?
17.7K
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Sustainable Development
12.9K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...
