Abstract
Integrating the Use of GIS and Mathematical Programming in Optimal Land-Use Allocation in Nueva Ecija, Philippines
Track: Agriculture
Author(s): Cheryll Casiwan, Teruaki Nanseki, Takuya Karasaki
The study explored the sue of Geographical Information Systems (GIS) and mathematical programming as complementary tools in developing optimum land-use allocation plan for the agricultural areas of Nueva Ecija province in the Philippines. GIS was used to assess and delineate areas suitable for the different rice-based production patterns based on the physical characteristics of the area, namely: slope, soil texture, geomorphology, agroclimatic, goundwater level, and irrigation availability. Using the GIS results as land constraints, mathematical programming incorporating risk factor was then applied to determine the optimal agricultural land-use allocation that maximizes the total returns from rice-based farming.
