Geospatial Assessment of Potential Agarwood (Aquilaria malaccensis) Cultivable Areas in Assam, India: A Remote Sensing and GIS Approach for Sustainable Agroforestry

Abstract Agarwood (Aquilaria malaccensis), a critically endangered species prized for its resinous heartwood, represents one of the most valuable agroforestry commodities in Northeast India. Assam, with its favorable Agro-climatic conditions and centuries-old cultivation tradition, is a global production hub. However, the absence of systematic spatial data on existing plantations and potential cultivation zones constrains evidence-based planning. This study presents a comprehensive geospatial assessment using Resourcesat-2A LISS-IV satellite imagery (5.8 m), Support Vector Machine (SVM) classification, and mobile-based field validation (AXOM FIELD application). We mapped 30,963 hectares of existing plantations across fourteen (14) districts and identified approximately 1,99,602 ha of potential or additional cultivable area. Tinsukia (30,842 ha), Golaghat (28,394 ha) and Karimganj (23,293 ha) emerged as top potential districts. Three major development Corridors were delineated for the expansion of Agarwood cultivation in Assam, these are : (1) Upper Assam corridor, North Bank corridor and Barak Valley corridor. The study demonstrates the efficacy of integrating remote sensing, GIS and GPS based validation process for agroforestry resource assessment and provides a spatially explicit evidence base for sustainable agarwood expansion and conservation in Assam.
