Abstract
ABSTRACT Ecotourism is the nature-based economic sector essential for sustainable local economic development. The present study aims to design suitable sites for ecotourism using the GIS-based Criteria Importance Through Inter Criteria Correlation (CRITIC) technique in the Darjeeling Himalayan region of India. The study attempts eight essential factors for evaluating the suitability map. The suitability map was categorized into four classes: Highly Suitable, Moderately Suitable, Marginally Suitable, and Least Suitable. The result revealed 786.23 sq. km (33.81%) as highly suitable, 797.549 sq. km (34.30%) as moderately suitable, 438.48 sq. km (18.86%) as marginally suitable, and 303.01 sq. km (13.03%) as least suitable. The result shows northern and north-western parts, namely Jorebunglow Sukiapokhri, Mirik, Kurseong, Rangli-Rangliot blocks, and the north-eastern parts Kalimpong I and Kalimpong II blocks, as highly suitable zones for ecotourism development. Finally, the receiver operating characteristic (ROC) and area under curve (AUC) analyses were used to validate the suitability map. The model validation with an AUC-ROC value was assigned 0.845, suggesting that the outcome is highly reliable with ground truth. The study can be helpful for policymakers to understand the spatial information of ecotourism in Darjeeling Himalaya.
