概括
全球水产养殖产量分布不均,尽管其增长. 新的指标显示,平等性正在增加,但仍然落后于渔业和肉类生产,突出了平衡发展的未开发潜力.
科学领域:
- 粮食安全和抗灾能力
- 全球粮食系统全球粮食系统
- 可持续的水产养殖
背景情况:
- 水产养殖是一个快速扩张的粮食生产系统,对全球粮食安全至关重要.
- 水产养殖产品在各国之间分布不均,这是一个尚未全面研究的重大问题.
- 不平衡的增长可能会危及粮食安全和性,但意味着未开发的潜力.
研究的目的:
- 开发一个创新的指标系统,以评估全球水产养殖产品的分布.
- 在五十年 (1970-2020年) 期间,分析了大约200个国家的水产养殖发展情况.
- 通过新的指标来衡量水产养殖生产的包容性和平衡性:人气和平价.
主要方法:
- 使用"有效国家数量" (ENC) 作为生产分配的基本指标.
- 开发了两个新型指标,人气和平价,扩展了ENC测量.
- 评估了许多国家和物种群体的1970年至2020年的水产养殖发展情况.
主要成果:
- 水产养殖已经成为一个全球性企业,近90%的国家参与其中.
- 水产养殖的普及表明,在大多数研究的物种群体中都有增长的潜力.
- 从1970年到2020年,水产养殖的平价在全球范围内有所增加,但仍然低于捕捞渔业和陆地肉类生产.
结论:
- 尽管增加了水产品的平等性,但全球水产养殖业的发展仍然不平衡,这表明了超出比较优势的因素.
- 这种不平衡既给粮食安全带来了风险,也为增长带来了机遇.
- 将水产养殖的受欢迎程度和平等性作为政策指标可以促进更具包容性和平衡的发展.

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.

3.3K
A complete procedure for testing a claim about a population proportion is provided here.
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
