Second-tier community forestry organisations and equitable resource management in the Maya Biosphere Reserve, Guatemala por Millner, N., Penagaricano, I., Fernández, M., Snook, Laura K.

“…Whilst community forestry programmes have combined sustainable forestry with community empowerment and poverty alleviation since the late 1970s, the role of intermediary organisations in shaping the technical and political capacities of forest user groups has rarely been systematically studied. The long-term durability of community forestry groups has been linked with the congruence between local and national determinations of tenure rights, and the involvement of local communities in determining the ‘rules' that govern the management of the forests. …”
