Mapping the Suitability of Planting Rubber Tree under Diﬀerent Climatic Conditions
ThepapermapsthesuitabilityofplantingrubbertreeintheprovinceofSouthernLeyteusing diﬀerent planting requirements under four types of climatic conditions through Quantum Geographic Information System or QGIS. Furthermore, this study tries to determine the size of areas in the province suitable for planting rubber tree under the four conditions and determine if there are signiﬁcant variations. The use of QGIS in mapping the suitability and determining the size of the areas of the diﬀerent suitability categories under various climatic conditions provided a clear picture of the ﬁtness of planting rubber trees in the province. Analysis of variance was used to determine if there are signiﬁcant diﬀerences in size of areas suitable for farming rubber tree under diﬀerent climatic conditions. Results showed that the size of areas under diﬀerent suitability categories signiﬁcantly diﬀered. Further, the size of the areas under diﬀerent suitability categories also considerably varied under various climatic conditions where the more signiﬁcant change is seen with the inclusion of ﬂooding and landslide into the mapping. This study concluded that rubber tree cultivation in Southern Leyte is aﬀected by diﬀerent climatic conditions but most signiﬁcantly by natural hazards like ﬂooding and landslide.
