概括
小规模渔业对全球粮食安全和生计至关重要,它提供了40%的捕捞量,支持数百万人口. 赋予渔民治理权力对于防止边缘化和实现可持续发展目标至关重要.
科学领域:
- 渔业科学
- 可持续的发展
- 粮食安全
背景情况:
- 尽管小规模渔业在消除贫困,饥饿和营养不良方面发挥着重要作用,但经常被忽视.
- 可持续发展目标的目标是"不让任何人落后",强调需要专注于像SSF这样的脆弱部门.
研究的目的:
- 量化SSF对全球粮食安全,营养和生计的多维贡献.
- 评估SSF产生的经济价值和就业机会.
- 确定需要采取的关键行动来支持SSF,防止渔民被边缘化.
主要方法:
- 采用了基于数据的多维协作方法.
- 估计了全球渔业捕获量,饮食摄入量和生计依赖.
- 计算了SSF的经济价值.
主要成果:
- 在全球渔业捕捞总量的至少40% (3730万) 提供SSF.
- 为23亿人提供必需的微量营养素,占其饮食摄入量的20%.
- 在全球范围内,每12人中就有1人依靠渔业资源谋生,渔业产生的经济价值占总值的44% (约合772亿美元).
- 亚洲的SSF支持最大的种群,非洲的SSF提供了最多的捕捞和营养,而大洋洲的SSF改善了最多的生计.
结论:
- 在实现可持续发展,减少贫困和粮食安全方面,SSF发挥着至关重要的作用.
- 必须采取有针对性的行动,特别是加强渔民参与共享管理和治理.
- 没有有效的管理和治理,数以百万计的渔民和渔业工人面临着越来越严重的边缘化.

01:43Sustainable Development
13.2K
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.

01:06Primary Production
23.5K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.
