AB Forest conversion to coffee-based agroforestry initiallyleads to a decrease in the rate of litterfall and the standinglitter layer covering the soil, reducing food for earthwormsand replenishment of soil organic matter (SOM) and likelyrelated to a reduction of soil macroporosity. On slopinglands, a reduction of macroporosity and soil cover is likelyto increase overland flow and erosion.This research was aimed at quantifying litter thickness,earthworm populations and soil macroporosity in responseto land use change, in the Sumberjaya benchmark area (WestLampung), by comparing (a) remnant forest as a control,(b) multistrata shaded coffee with fruit and timber trees as well as the nitrogen-fixing (Erythrina sububrams and/orGliricidia sepium) as shade trees, (c) shaded coffee withthe same nitrogen-fixing Erythrina sububrams and/orGliricidia sepium as shade trees , (d) monoculture (sun)coffee. Plots were selected with a minimum age of 7 years,in three slope classes: (a) flat (0-10o), (b) medium (10-30o)and (c) steep ( > 30o). The measurements were carried out inNovember 2001 to Juli 2002.
