tailieunhanh - BIOETHANO

The dehesa is an ancient agrosilvopastoral system created by farmers to raise livestock, mainly on private lands. This system is highly appreciated by society and enjoys legal protection of the authorities because it is rich in biodiversity, a home to critically endangered species (Iberian lynx, imperial eagle and black vulture); a significant carbon sink; ethnologically and anthropologically valuable (culture and traditions); and is known for its scenic value. The dehesa also underpins rural development and is valuable for, inter alia, ecotourism and rural tourism; hunting and shooting; fire prevention; wood and charcoal; and for fodder (grass and acorns). However, most of these values do not produce any benefit. | BIOETHANOL Edited by Marco Aurelio Pinheiro Lima and Alexandra Pardo Policastro Natalense Bioethanol Edited by Marco Aurelio Pinheiro Lima and Alexandra Pardo Policastro Natalense Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2012 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
