The book examines the nature of Nicaragua’s forestry sector, the national context of financial, administrative and political decentralization and its relation to other development and poverty alleviation policies, the legal and institutional framework of forest management and the roles played by regional and municipal governments, and the problems faced by forest-dependent groups for gaining access to forest resources and benefits and the effects of decentralization on these processes.…”
