Item Details
SUMMARY

RIOS can be used to decide priority areas for investment to maximize the watershed services outcome. One of its output is the expected change of LULC from due to the optimized investments / intervention, which can be used as a scenario LULC raster. The model supports 30 basic land cover classes plus 20 crop types.

Only 7 transitions are allowed in the current version of the tool: Keep native vegetation, unassisted revegetation, assisted revegetation, agricultural vegetation management, ditching, fertilizer management, and pasture management.

INPUT - REQUIRED [Spatial] LULC map, DEM, beneficiaries distribution [Non-spatial] Weight of factor importance, allowed activities on LULC type, floating budget, activity cost, activity-transition table
INPUT - OPTIONAL Weight of objectives (if multiple objectives are considered)
OUTPUT LULC rasters under the baseline situation and the optimized investment scenario. Activities and places to invest in. Ecosystem services outcome.
HOW ARE SCENARIOS DECIDED?

The model first assigns activities and interventions to certain areas based on user-defined budget and goals, and then generates the scenario LULC map based on interventions made.

COST Free
FORM Desktop Python application
CAN I ALTER THE MODEL? Yes
SCALE/RESOLUTION No restriction. default estimates are developed for Latin America, therefore local estimates are needed if used outside of Latin America. Also, the scale/resolution should be proper to capture the watershed process.
REQUIRE GIS TOOL TO RUN THE MODEL? No. However, GIS tools are required for pre / post-processing.
