Environmental vs ecosystem services

  • Environmental services - a function of broader environment (including climate and terrain) and thus not manageable at the local and regional scale of interventions
  • Ecosystem services - a service provided by the ecosystem on the ground (vegetation, soil, wetlands) and can thus be managed for positive and negative outcomes
    • eg cloud forests are wet environments (high precip, low evap. because of cloud) much of the water they produce is thus an environmental service
  • Cloudwater (fog) inputs are an ecosystem service as they are dependent on trapping by forest. No forest, no trapping.

Hydrological ecosystem services

  • Provisioning of water quantity and quality
  • Regulating of flow peaks and troughs (floods and droughts)
  • Role in some hazards and hazard mitigation
  • Other cultural, spiritual and recreational
  • Water supports other services eg plant production
  • Oversimplifications: forests generate more water, forests prevent floods, forests sustain dry season flows,forests improve water quality
  • Depends on landscape and climate, type of forest, relative to what land use, distribution of beneficiaries. The geography is key.
