Forest fire management related initiatives of Forest Survey of India covers the following areas :
|Near Real Time (NRT) Forest Fire alerts|
|Forest Fire Pre warning alerts|
|Burnt scar studies|
Forest Survey of India has been alerting State Forest Departments of forest fire locations detected by the MODIS (Moderate Resolution Imaging Spectro-radiometer) sensor on-board Aqua and Terra Satellites of NASA since 2004. As each satellite has two passes over the country daily, fire alerts of 1km X 1km resolution pertaining to 10.30 am, 1.30 pm, 10.30 pm and 1.30 am are sent to the users. From the year 2017, FSI has incorporated another sensor SNPP-VIIRS (Suomi-National Polar-orbiting Partnership - Visible Infrared Imaging Radiometer Suite). SNPP-VIIRS has spatial resolution of 375m and two equatorial passes at 1.30 am and 1.30 pm. It has a good night time detection capability as compared to MODIS and can also detect small fire and under canopy fire.
With the launch of “Forest Fire Alert System 2.0”, this entire process has been made completely automated which has effectively reduced the dissemination time lag.
Forest Fire Alerts are disseminated together with Google Earth compatible KML files through email to the nodal officers of State Forest Departments.A registered user who is registered on the FSI website can also avail forest fire alerts as SMS for their area of interest which can now be chosen upto ‘Beat’ level (as per the data available from State).

As on June, 2018 around 33,690 users with 37,366 unique subscriptions have registered under the
“Forest Fire Alert System 2.0”.

From the year 2019 onwards, it has also been planned to track and alert the users for ‘Large Forest Fires’ in their subscribed areas.
Forest Survey of India, with years of experience with the repository of fire related data, developed in 2016, an indigenous “Pre Warning Alert System”. The alerts to State Forest departments are based on parameters like Forest Cover, Forest Type, Climatic Variables (Temperature and Rainfall) and recent fire incidences over the area. The pre warning forest fire alerts are communicated in the form of KML files through email to the nodal officer of the State Forest Departments. These alerts which are generated based on short term weather variables, are valid for the ensuing week. In the year 2017, the analysis was shifted to a grid based system (5km x 5km) allowing parameters to be quantified and represented within these grids. Certain additional parameters were also included to make the “Pre Warning Alert System” more robust.
While it is important to timely detect forest fire for taking remedial measures, it is equally important to assess forest area affected by the forest fires to assess damage to forest and bio-diversity as well as to plan restoration measures.
In the year 2015 and 2016, high temporal data (5 days receptivity) from Indian Remote Sensing (IRS) AWiFS (Advanced Wide Field Sensor) having a spatial resolution of 56 m was used to delineate burnt scars. The data of burnt scars were shared with SFD’s for their feedback.
Presently, FSI is also working on developing a semi-automated methodology for burnt area assessment and severity class classification using modern technologies
