1.4 How Does Ecosystem Restoration Combat Climate Impact?

Ecosystem restoration is a powerful nature-based solution to climate change.

  • Carbon Sequestration: Healthy ecosystems, particularly forests, wetlands, and oceans, act as "carbon sinks" by absorbing large amounts of carbon dioxide from the atmosphere and storing it in biomass (trees, plants) and soil.
    • Example: A growing forest continuously pulls CO2 from the air through photosynthesis. Peatlands and mangrove forests are particularly effective carbon sinks, storing vast amounts of carbon in their soils.
  • Building Resilience: Restored ecosystems are more resilient to the impacts of climate change. For example:
    • Healthy wetlands and coastal ecosystems can absorb storm surges and reduce flood damage.
    • Diverse forests are more resistant to pests and diseases, which can be exacerbated by changing climates.
  • Biodiversity Protection: Climate change poses a significant threat to biodiversity. Restoration efforts often focus on restoring habitats, which in turn supports a wider variety of plant and animal species, making ecosystems healthier and more stable.
  • Water Regulation: Restored forests and wetlands improve water infiltration, reduce soil erosion, and regulate water cycles, which can mitigate the impacts of droughts and floods.
