The management of many protected areas struggles to meet objectives, a problem that, as previous sections have shown, is linked to limited human and financial resources. Management effectiveness improved mainly in extractive reserves, ecological stations and national forests, as well as in protected areas in the Amazon and Cerrado biomes. The better performance was directly linked to the result-based approach of the programme, the considerable financial resources invested in ARPA areas and the fact that both federal and state governments are required to contribute human resources for managing these areas (WWF and ICMBio, 2012).
