摘要:Sustainable food systems (FS) require providing food and other goods and services to humans satisfying
food security, right to food, income, social justice and resilience, without degrading human health and hiving
high environmental performance. The environmental performance of FS can be evaluated using Life Cycle
Assessment. However, research on the impact that FS activities, e.g. crop production have on the capacity
of farm-based agroecosystems to provide goods and services to humans is still incipient. Our underlying
aim was to understand how FS impact on the provision of agroecosystem services and how this relates
to the environmental performance of FS, as a basis for supporting decision-making on how to make FS
more sustainable. We propose the Agroecosystem Service Capacity (ASC) as a method for assessing farmbased
agroecosystem services, it builds on the Ecosystem Service Matrix by Burkhard et al. (2009) and
assesses land cover classes against 20 agroecosystem services. The method was applied to eighteen farmbased
agroecosystems in Bolivia and Kenya. Here we present two examples for exploring its potentials and
limitations. The ASC operates on the basis of land cover class units and permits the calculation of an aggregate
ASC-index for farm-based agroecosystems forming part of a specific FS.
