  3. 3. Ecological Transition: enter the Anthropocene Intact, Natural Environments Engineered Infrastructure/ Markets Increased capital, Increased inequality The Poor Loss of natural insurance: food, shelter, etc.
  4. 4. Conservation as Public Health Intervention
  5. 5. 85% of all flora and fauna in Madagascar is endemic to the country 50% of floral diversity is found in the Makira watershed Lemurs and all native carnivores are endemic only to Madagascar Makira Watershed
  6. 6. Wildlife as an Ecosystem Service
  7. 7. BUSHMEAT AND ECONOMIES The bushmeat trade is a local to global market that is valued at billions of dollars per year
  8. 8. Biodiversity Targeted
  9. 9. • 7 yrs of panel data from 2 adjacent NPs for more than 650 hh • Only 2% of wildlife harvest is sold (n=232, from 194 hh) • Wildlife demand curve • Two-stage least squares panel data method using IVs
  10. 10. • Average ecosystem service value per hectare was $0.42/ha • 57% of annual cash income (95%CI: 1.3-190.7%) • Imputed price of wildlife and its consumption were highly correlated where higher prices led to reduced consumption • Welfare value (foregone benefits from conservation) • 2/3 of wildlife is harvested illegally
