概括
保护国家公园以外的地区对于生物多样性和生态系统服务至关重要. 恢复坦桑尼亚的野生动物走廊每年可能会产生数百万美元的收益,这凸显了综合保护战略的必要性.
科学领域:
- 生态与保护生物学 生态与保护生物学
- 环境经济学环境经济学
- 土地使用科学 土地使用科学
背景情况:
- 由于不可持续的土地使用而导致的息地丧失是生物多样性丧失的主要驱动因素,人类人口增长加剧了这种情况.
- 保护区网络 (PAN) 是一个关键的保护战略,但可以忽视保护区以外的地区 (OPAN) 的生物多样性和生态系统服务 (ES).
- 了解OPAN中人类与生物多样性的相互作用对于有效的保护和可持续的生态系统服务提供至关重要.
研究的目的:
- 通过基于生态系统的保护 (EBC) 框架,评估坦桑尼亚OPAN中选定的ES的货币价值.
- 评估生物多样性和土地使用/土地覆盖 (LULC) 类型如何影响OPAN中的ES值.
- 模拟到2030年恢复优先野生动物走廊的潜在ES益处.
主要方法:
- 在坦桑尼亚应用一种新的基于生态系统的保护 (EBC) 框架.
- 对生物多样性和LULC类型的评估,以确定OPAN中选定的ES的货币价值.
- 来自野生动物走廊恢复的未来ES世代的场景建模.
主要成果:
- 水体通过供水和洪水控制提供了最高的ES价值 (128亿美元).
- 米博林区的OPAN显示出高ES价值 (124亿美元),主要是由于防洪,供水和碳储存.
- 恢复野生动物走廊中的退化土地每年可以产生6280万美元的收入,碳储存是主要贡献者.
结论:
- 在OPAN中ES的货币价值是显著的,并受到LULC类型,生物多样性和退化水平的影响.
- 将OPAN纳入EBC框架对于整体保护至关重要,将当地恢复工作与国家和全球生物多样性目标联系起来.
- 恢复野生动物走廊内的退化土地为加强ES和生物多样性保护提供了巨大的机会.

What is Conservation Biology?
23.9K
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.

Conservation of Small Populations
16.6K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Sustainable Development
14.7K
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.

Ecological Niches

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.
