This paper analyzes the impact of national development policy on land cover change and associated carbon fluxes at a Peruvian Amazon frontier. Remote sensing and field transects reveal changes in forest carbon stocks and accumulation rates. Deforestation was most rapid along the Interoceanic Highway during 1986-91 when credit and guaranteed markets were available, resulting in emissions of 708,000 Mg Cyr(-1), of which 14% was offset by secondary regrowth. Despite continued population growth, deforestation slowed during 1991-97 when fiscal austerity measures were imposed, resulting in emissions of 389,000 Mg Cyr(-1), of which 41% was offset by regrowth. Strategies to conserve frontier forests are compared in terms of carbon, biodiversity and economic costs and benefits. (C) 2003 Elsevier Ltd. All rights reserved.
