From the reviews: “This book presents much useful and innovative work for researchers and policy-makers who specialize on physical-science or economic aspects of upland soil, water, and agriculture. … This book is undoubtedly an empirically rich analysis of various aspects of land use constraints and changes occurring in mountainous regions of Southeast Asia, and it updates the literature significantly.” (Tim Forsyth, Mountain Research and Development, Vol. 34 (1), February, 2014)
