CEnREP Camp Resources 2011 Pires de Matos, Sills, NC State University The first Forestry Code was created with Federal Decree N , from The concept of Legal Amazon was created in 1953 (Federal Law 1.806). The Forestry Code was substantially revised by Federal Law n , from Defines small properties: Small property in Legal Amazon <150 ha. Minimum of 80% of household income from agro-forestry or extraction. Defines Permanent Protection Areas (Área de Preservação permanente – APP): Protect water resources, soil, landscape, biodiversity and population’s wellbeing. Defines Legal Reserve (Reserva Legal – RL): Preserve ecosystems and biodiversity. Environmental Law in Brazil

CEnREP Camp Resources 2011 Pires de Matos, Sills, NC State University Conclusions and ongoing work Environmental legislation is not effective but farmers appear to “acknowledge” its presence. Policy implications: Improved enforcement decelerates deforestation (obvious). Enforcement above incentives/subsidies (e.g. REDD+)? Working with sub-samples and additional covariates. Incorporating HH survey data.
