FAO’s VCA-Tool is a software that has been developed for Value Chain Analysis to analyse and compare the effects of different policy options for agriculture and sustainable rural development. The VCA software allows you to build different scenarios and to analyse the socio-economic impact of various policies such as domestic prices liberalization, opening to international trade, new technologies adoption, etc. The software allows you to build a baseline scenario which corresponds to a benchmark situation and once you generate the policy measures or changes in the value chain, their impacts will modify the original reference scenario. The software comprises a user manual.
