A Transboundary Political Ecology of Volcanic Sand Mining

Abstract

Sand, the main ingredient of cement, glass, and asphalt, is being mined for urban development and global production at a pace that exceeds natural renewal. Yet research on the sustainability of sand mining has concentrated on extraction rates and socioecological impacts in rivers and coastlines. The potential of active volcanoes to generate a renewable supply of sand through cyclical or intermittent eruptions has been understudied, as have the asymmetrical power relations that animate around this dangerous but financially lucrative industry. This article uses a transboundary political ecology framework to examine the geographically dispersed development interests that drive volcanic sand mining on Mount Merapi, Indonesia’s most active stratovolcano. I argue that to make Mount Merapi’s volcanic sand trade more sustainable, collaborative forms of environmental governance are needed to bridge critical gaps in knowledge about industry practices that create environmental impacts extending well beyond the volcano’s slopes. I develop this argument through three sets of transboundary political ecology themes centered on (1) knowledge boundaries that inform differentiated place-based practices; (2) the transboundary governance dilemma posed by disconnects between upstream mining practices and downstream environmental impacts; and (3) the potential of cross-border governance networks to collaboratively address these policy deficits.
