Abstract
Antle and Valdivia (2006, Australian Journal of Agricultural and Resource Economics 50,
1–15) proposed a minimum-data (MD) approach to simulate ecosystem service supply
curves that can be implemented using readily available secondary data and validated the
approach in a case study of soil carbon sequestration in a monoculture wheat system.
However, many applications of the MD approach are in developing countries where
semi-subsistence systems with multiple production activities are being used and data
availability is limited. This paper discusses how MD analysis can be applied to more
complex production systems such as semi-subsistence systems with multiple production
activities and presents validation analysis for studies of soil carbon sequestration in
semi-subsistence farming systems in Kenya and Senegal. Results from these two studies
confirm that ecosystem service supply curves based on the MD approach are close
approximations to the curves derived from highly detailed data and models and are
therefore sufficiently accurate and robust to be used to support policy decision making.
