Land use change in tropical watersheds: evidence, causes and remedies.

Book cover for Land use change in tropical watersheds: evidence, causes and remedies.

Description

This book studies land use change in tropical landscapes, with particular emphasis on the economic processes that influence rates of land degradation and forest clearing. Multidisciplinary contributions draw lessons from data collected between 1992 and 2004 in the Manupali watershed in southern Philippines. Through this detailed case study, the book documents forces leading to land use changes, in...

Chapter 4 (Page no: 58)

How do national markets and price policies affect land use at the forest margin? Evidence from the Philippines.

This chapter uses time series data (1994-99) from local and regional agricultural markets to show how national markets have shaped incentives for agricultural expansion and resource allocation at the forest margin of Manupali watershed in Lantapan municipality, Bukidnon, Philippines. It is shown that commodity market development, along with policy biases, has contributed to deforestation and the adoption and spread of relatively erosive crops, produced using relatively land-degrading technologies, in the upland watershed. It is demonstrated that in spite of remoteness, the farmers in the study area produce for markets that are integrated in the national system. Anecdotal evidence of the importance of macroeconomic trends in driving upland migration and land use patterns is provided with some additional contemporary support by the finding that the stability of market price relationships is a function of price stability in the overall Philippine economy.
