Identification of potential expansion areas for rubber is essential to increase local production and improve their quality while taking advantage of the market demand. A database on existing plantations of nine provinces in the Philippines identified as major production areas of rubber and cacao was developed. Using geographic information (GIS), remote sensing (RS) and other inventory techniques, habitat suitability, and niche modelling were conducted to determine the potential expansion of production areas after culling out restricted areas and existing plantation areas.
