Ecosystem-based adaptation

Definition

Ecosystem-based adaptation is a strategy that uses biodiversity and ecosystem services to help communities adapt to the adverse effects of climate change. It emphasizes the importance of natural systems in enhancing resilience against climate-related impacts such as flooding, drought, and sea-level rise. By integrating conservation and sustainable management practices, this approach not only protects ecosystems but also supports livelihoods and improves human well-being.

5 Must Know Facts For Your Next Test

1. Ecosystem-based adaptation promotes practices like restoring wetlands or creating green roofs to absorb excess rainwater and reduce flood risk.
2. This approach is cost-effective as it often utilizes existing natural features rather than relying solely on engineered solutions for climate adaptation.
3. Ecosystem-based adaptation can improve food security by enhancing the productivity of ecosystems that support agriculture and fisheries.
4. Engaging local communities in ecosystem-based adaptation efforts ensures that strategies are culturally appropriate and meet the specific needs of those most affected by climate change.
5. The success of ecosystem-based adaptation relies heavily on maintaining healthy ecosystems, as degraded environments are less capable of providing essential services.

Review Questions

• How does ecosystem-based adaptation utilize biodiversity to enhance community resilience against climate change impacts?
  • Ecosystem-based adaptation leverages biodiversity by utilizing the natural functions of various species and ecosystems to buffer against climate change effects. For instance, diverse plant species in wetlands can improve water retention, reduce flooding, and filter pollutants. This adaptability not only protects ecosystems but also provides essential services to communities, helping them withstand adverse weather events while promoting sustainable practices.
• Discuss the advantages of using ecosystem-based adaptation over traditional engineering solutions for flood risk management.
  • Ecosystem-based adaptation offers several advantages compared to traditional engineering solutions. First, it is generally more cost-effective since it often relies on restoring or maintaining existing natural systems rather than constructing new infrastructure. Second, it enhances ecological health and biodiversity, which can lead to additional benefits such as improved air quality and increased recreational opportunities. Finally, by engaging local communities in these strategies, ecosystem-based adaptation fosters a sense of ownership and stewardship that can further bolster resilience.
• Evaluate the long-term impacts of implementing ecosystem-based adaptation strategies on coastal resilience and community well-being.
  • Implementing ecosystem-based adaptation strategies can significantly enhance coastal resilience by restoring natural barriers like mangroves and coral reefs, which provide critical protection against storm surges and erosion. Long-term impacts include increased biodiversity, improved water quality, and enhanced carbon sequestration capabilities. Additionally, these strategies can lead to better community well-being through increased access to resources like fisheries and recreational areas, as well as fostering social cohesion among community members involved in conservation efforts. Ultimately, embracing ecosystem-based adaptation not only mitigates climate risks but also promotes sustainable development.
