Telangana Remote Sensing Applications Centre (TGRAC) has established a protocol Integrated Seasonal Condition Monitoring System (ISMS) based on developed methodology of NRSC/MNCFC. The different activities carried out through ISMS commence with acquisition of MODIS (250m) and AWiFS (56m) satellite data. The satellite data being processed and NDVI and NDWI indices are developed. Based on these indices deviation with respect to normal year (2013), VCI calculation and Mandal wise Statistics are derived. The agricultural situation is assessed incorporating Rainfall deviation, Command and non command areas and dry spell and information followed Weekly sowing progress and Reservoir levels. The agricultural situation is classified in three to four categories i.e. Normal, Watch, Alert for June to August and Normal, Mild, Moderate and Severe for September to October. This output is verified through ground truth, additionally in context of the state specific drought declaration criteria.

Objectives:

1. Concurrent monitoring of seasonal conditions using remote sensing, extensive weather network data and continuous ground truth.
2. Develop an early warning (monitoring) of drought using suite of indicators, which will help to increase drought preparedness, and identify and implement appropriate Disaster Risk Reduction (DRR) measures.
3. Early Warning to the Districts/Mandals

Area of Study:

The study is carried Mandal wise for entire Telangana.

Duration of the Study:

June to November (Kharif Season, every year)
