Hypothesis
Forest cover change is a function of strength and enforcement of local social institutions.
Conclusion
The study found a minor decrease of 7% total forest cover from 1984 to 2000, but an overall net increase of 4% during the period from 1993 to 2000.
Supporting Evidence
- The study analyzed Landsat images covering 5500 km2 to assess forest cover changes.
- Results indicated that areas with well-defined property rights showed either regenerating or stable forest cover.
- Forest regeneration was linked to decreased human population and livestock grazing pressure.
Takeaway
The study shows that forests in Madagascar can recover if local rules about land use are followed and if there are fewer people and animals using the land.
Methodology
The study used Landsat images from three different years (1984, 1993, and 2000) to analyze forest cover changes and the role of local institutions.
Potential Biases
Potential biases may arise from the reliance on satellite imagery and local informant interviews.
Limitations
The study's findings may not be generalizable beyond the specific regions of Madagascar analyzed.
Participant Demographics
Informants included local villagers, forest officials, and key informants from ten local communities.
