## STATEMENT  REFERRED  TO  IN  REPLY  TO  PARTS  (a)  TO  (d)  OF  LOK  SABHA STARRED QUESTION NO. 229   DUE FOR REPLY ON 15 TH  DECEMBER, 2015.

(a): Under  NADAMS  Project,  periodic  assessment  &  district/sub-district  level agricultural drought is carried out using various types of data i.e multi resolution/multi sensor satellite based remote sensing data, district/sub- district level rainfall data, crop sowing information from States, district level irrigation statistics, estimated soil moisture etc.

The  methodology  of  NADAMS  project  essentially  reflects  the  integration  of satellite  derived  crop  condition  /surface  wetness  indices,  integrated  with  rainfall  and crop  area  progression  to  evolve  decision  rules  on  the  prevalence,  intensity  and persistence of agricultural drought situation.

The various indices/inputs used for agricultural drought assessment  are: Normalized Difference Vegetation Index (NDVI), Normalized Difference Wetness Index (NDWI),  Shortwave  Angle  Slope  Index  (SASI),Vegetation  condition  Index  (VCI),  Soil Moisture  Index  (derived  from  soil  water  balance  approach),  Rainfall  data(rainfall deviation).

The Monitoring of agricultural drought under NADAMS project is carried out on monthly/fortnightly  basis  for  the  kharif  season  (June-October).  During  June-August drought  warning  (alert,  watch  and  normal)  and  during  September-October  drought conditions (normal, mild, moderate & severe) are given.

(b):     Currently 14 States are covered under NADAMS.  These are  Andhra Pradesh, Bihar, Chhattisgarh, Gujarat, Haryana, Jharkhand, Karnataka, Madhya  Pradesh, Maharashtra,  Odisha,  Rajasthan,  Tamil  Nadu,  Telangana,  Uttar  Pradesh.    In  these States district level agricultural drought assessment is carried out. At present sub-district level  assessment  is  carried  out  in  only  5  States  namely  Andhra  Pradesh,  Haryana, Karnataka, Maharashtra and Telangana.

The States selected under this project are based on twin criteria of agriculturally important and vulnerability to drought.

(c) & (d):       Telangana is already covered in NADAMS Project.
