The study was carried out in four mountain districts of the state of Himachal Pradesh, India with the objective of delineating spatio-temporal changes in area, production and productivity of apple. ArcGIS platform was used in a windows environment to delineate spatial changes in area, production and productivity over four decades i.e. 1984-2020 using data from the authorized State Departments. It was observed that there is an increase in area under apple and has spread to non-traditional apple growing areas. The production of apple has in general increased as a consequence of increase in area. Apple productivity has fallen in many areas over decades, but this fall in productivity has been compensated by efficient management and following best agro-techniques. The lower areas in the four mountain districts have experienced loss of apple plantations but has been compensated by an increase in areas at higher elevations. The impact of warming has still not crossed the available amplitude o
