บทคัดย่อ (EN): Prediction of present and future distribution of natural rubber, Hevea brasiliensis, was attempted using the Maximum Entropy species distribution model in South and Northeast India. Preliminary results of model simulation on present distribution of natural rubber in Tripura state in Northeast India was validated with the satellite image based current spatial rubber map and found to be highly correlative. Future distribution of natural rubber was predicted for South and Northeast India for the year 2050 using the bioclimatic variables of SRES-A1B scenario generated by Intergovernmental Panels for Climate Change (IPCC). Present distribution of natural rubber was predicted by the model indicates that South-western aspects of the southern parts of western Ghat in the states of Kerala, and Kanyakumari district of Tamil Nadu are the dominant areas under natural rubber. In NE India, natural rubber distribution was more predominant in the West and South Tripura districts, Northern Mizoram, Western Meghalaya and lower Assam. The model predicts that natural rubber expand more towards Northern parts of Western Ghat along the Malabar coast, upper Assam, Northern Tripura and parts of Meghalaya. The model performance was assessed Using receiver operating characteristic (ROC) curves The area under the ROC curve (AUC) for training data and test data of natural rubber were 0.983 and 0.990 respectively indicating that omission of training and test data by the classifier is less than 30% and 10% respectively. The jackknife plot of AUC and regularized training gain indicates that Bio7 (annual range of temperature) is the most effective single variable followed by diurnal range of temperature, isothermality and temperature seasonality that determine the future distribution of natural rubber in India. Relevance of the present findings is discussed in the context of global climate change and the increasing demand for natural rubber, both domestically and globally.
