💰 Economic incentives: PES, ecotourism, certifications

Big idea: Forests recover faster when people can earn money by keeping forests standing, not by clearing them.

1) Payment for Ecosystem Services (PES)

Payment for Ecosystem Services (PES) = paying landowners to conserve or replant forest.

  • Reduces deforestation by making conservation profitable
  • Encourages reforestation/restoration
  • Links to ecosystem services

2) Ecotourism

Ecotourism can fund parks and create jobs, so forests gain economic value alive.

  • Income for communities → support conservation
  • Revenue funds park management/enforcement
  • Forests become an asset rather than land to clear

3) Certifications (bonus example)

Certification can reduce pressure to clear forests by rewarding sustainable practices.

  • Incentive: access to higher-value markets
  • Encourages sustainable forestry/agriculture
  • Can reduce deforestation over time
