• We develop an extended ecosystem accounting system to estimate total income for individual agroforestry products.
• We estimate and integrate market and non-market product indicators.
• We discuss how the economic aims of landowners could affect management decisions and guide ecosystem conservation policies.
We develop an ecosystem accounting system to estimate individual products' biophysical and total income indicators. The ecosystem products are grouped into private and public activities and measured consistently with the principle of exchange value of the standard national accounts. Private products comprise timber, cork, firewood, conservation forestry, grazing, livestock, hunting, crops and private amenity, while the public ones comprise mushrooms, carbon, water, public recreation, landscape and threatened biodiversity services. Our accounting approach revises and extends the standard agricultural and forestry sector income accounts by incorporating intermediate products, natural growth, private amenity, carbon sequestration and capital gain. Furthermore, our approach extends the standard government sector income accounts by including the economic value of the consumption of public final products delivered by ecosystems on the basis of simulating prices for non-market products. We apply the agroforestry accounting system to a group of 39 agroforestry farm case studies in Andalusia, Spain. We provide results for two agroforestry farm groups: publicly owned coniferous forest and privately owned native hardwood forest (dehesa). Total income attained, on average, €140 per hectare in coniferous forests and €352 per hectare in dehesas. Cork natural growth and private amenity are the main products explaining private income in dehesa farms. Forestry activity products, particularly timber natural growth and the intermediate products of conservation forestry, are the main sources of private income in the coniferous forests. Public incomes from non-market products are the main contributors of total income in dehesas and forests.
