摘要:Climate changes in agriculture act on various climate variables (precipitation, temperature etc.) and at different times of crop cycles. This paper provides an evaluation of the economic impact of changes in multiple events and the associated uncertainty in an area of Sardinia, through a multidisciplinary approach, namely economic and agronomic. The economic approach uses a three stages Discrete Stochastic Programming model, while the irrigation requirements of some major crops for the agricultural economy of the area uses the EPIC agronomic model. The results show that the whole agricultural area adapt itself with a low cost, changing crops or cultural practices. This cost, however, is higher for certain types of farms that suffer a significant income reduction.
