Scenario analyses

The goal of the I/O model is to evaluate the wider regional economic effects of adopting mitigation strategies for land degradation. Mitigation strategies include the application of various structural, vegetative, management and agronomic soil and water conservation measures on rainfed land cropped to annual crops, ecological production of tree crops, and application of organic mulches on tree crops and possibly irrigated crops (annual crops, tree crops and irrigated crops being distinguished as separate economic sectors).

Based on the Cost-effectiveness modelling (section 3), we can alter input and output structures of the relevant sectors in the I/O model for a future land use situation (i.e. the after adoption situation). By exploring differences between different states (policies and technologies expressed in changes in the IO matrices), we can then derive implications for the wider regional economy. Other scenarios can be based on extrapolation of land use changes assessed by the ABM model (section 4.1) or on results from WB 1, 3 etc.
