tailieunhanh - ECOLOGICAL BASIS OF AGROFORESTRY part 1

Agroforestry is one of the sustainable approaches to land-use management where both agriculture and forestry combine into an integrated production system to get maximum benefits (Kidd and Pimentel, 1992; Nair, 1998). As per ICRAF (International Centre for Research in Agroforestry, now World Agroforestry Centre), ‘‘agroforestry is a deliberate integration of woody components with agricultural and pastoral operations on the same piece of land either in a spatial or temporal sequence in such a way that both ecological and economic interactions occur between them.’’. | ECOLOGICAL BASIS OF AGROFORESTRY Copyright 2008 by Taylor and Francis Group LLC ECOLOGICAL BASIS OF AGROFORESTRY Edited by Daizy Rani Batish Ravinder Kumar Kohli Shibu Jose Harminder Pal Singh CRC Press w J Taylor Francis Group Boca Raton London New York CRC Press is an imprint of the Taylor Francis Group an informa business Copyright 2008 by Taylor and Francis Group LLC CRC Press Taylor Francis Group 6000 Broken Sound Parkway NW Suite 300 Boca Raton FL 33487-2742 2008 by Taylor Francis Group LLC CRC Press is an imprint of Taylor Francis Group an Informa business No claim to original .
