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...

Simulating soil erosion and sediment yield in small upland watersheds using the WEPP model.

This paper outlines the development of hillslope and watershed-scale Water Erosion Prediction Project (WEPP) erosion simulation models for selected small upland sub-watersheds of the Manupali River in the Philippines. Soil erosion and sediment yield predictions are presented for selected sub-watersheds. In addition, the WEPP model is used to study changes in erosion and sediment yield that have arisen due to changes in land cover and land management practices in selected sub-watersheds. This paper also provides an overall assessment of erosion risk in the Manupali River watershed and demonstrates the strong linkage between land cover - as determined by smallholders operating in the watershed - and environmental outcomes.
