This book addresses the politics of environmental change in one of the richest areas of tropical rainforest in Indonesia. Based on field studies conducted in three agricultural communities in rural Aceh, this work considers a number of questions: How do customary (adat) village and state institutions work?

Will better outcomes emerge from revitalizing customary management, from changing state policies, or from transforming the way the state works? And why do projects designed by outsiders so often fail?The book describes how, as key actors interact, they create arrangements that effectively manage local resources, eclipsingadatand formal state management structures.

This book analyzes the political, legal, and economic dynamics shaping environmental outcomes across two districts in Aceh, one of the richest and most expansive areas ol³(
