for 13 States
MNCFC |Agricultural Drought Assessment Report, June 2012 1
Executive Summary
Agricultural Drought Assessment is essential for taking appropriate remedial measures for improvement of drought situation. Satellite based remote sensing data has been shown to be highly useful for crop condition assessment and drought monitoring. A very successful project called National Agricultural Drought Assessment and Monitoring System (NADAMS) had been developed by National Remote Sensing Centre (NRSC), ISRO, which envisages use of remote sensing and meteorological data for drought assessment of 13 agricultural important states of India. After the technology was transferred to Mahalanobis National Crop Forecast Centre (MNCFC), Department of Agriculture & Cooperation, this is the first report of national level agricultural drought assessment brought by MNCFC, in collaboration with NRSC. This report assesses agricultural situation of the country for the month of June, 2012.
Composite images of coarse resolution NOAA AVHRR data was used for 9 states
namely, Bihar, Chhattisgarh, Gujarat, Madhya Pradesh, Jharkhand, Orissa, Rajasthan, Uttar Pradesh and Tamil Nadu, while moderate resolution data from AWiFS/MODIS was used for 4 states namely, Andhra Pradesh, Karnataka, Haryana and Maharashtra. Crop condition has been assessed using satellite derived Normalized Difference Vegetation Index (NDVI)/(Normalized Difference Water Index) NDWI images. Shortwave Angle Slope Index (SASI) derived from MODIS data has been used to generate Area Favourable for Crop Sowing (AFCS). These satellite derived products have been integrated with Soil Moisture Index (derived using soil water balance approach) and IMD Rainfall data (rainfall deviation, number of dry weeks) for assessment of drought situation in each district of these 13 states.
During June 2012, with delayed monsoon and its slow progression, rainfall received
during June month was deficit in majority of the meteorological sub-divisions affecting the Kharif crop sowing activity. Anomalies of SASI indicated a large proportion of the agricultural area (>50%) in dry condition in the current season compared to normal monsoon year of 2011 in the states of Bihar, Jharkhand, Orissa, Uttar Pradesh, Tamil Nadu, Karnataka and Haryana. NDVI and its deviations do not indicate the commencement of agricultural activity and seasonal greenness in majority states particularly in Madhya Pradesh, Uttar Pradesh, Rajasthan, Gujarat, Bihar and Jharkhand states. Very low NDWI values in most of the states are the result of reduced rainfall and its poor distribution. More than 50% of agricultural area in majority states shows very large negative deviations from normal NDWI, reflecting the intensity of surface dryness over agricultural areas.
This current report presents the state level maps of above indices and the agricultural condition. It also presents, in tabular form, the district level drought situation (Normal, Watch and Alert).

'National Agricultural Drought Assessment and Monitoring System (NADAMS)' project, conceptualized and developed by National Remote Sensing Centre (NRSC), ISRO, Department of Space, provides near real-time information on prevalence, severity level and persistence of agricultural drought at state/ district/sub-district level. Currently, it covers 13 states of India, which are predominantly agriculture based and prone to drought situation. Agricultural conditions are monitored at state/district level using daily NOAA AVHRR data for 9 states. AWiFS (Advanced Wide Field Sensor) of Resourcesat (56 m resolution) is used for detailed assessment of agricultural drought at district and sub district level in four states. MODIS 250m, 500m derived NDWI, SASI datasets have also been interpreted to complement the assessment. Fortnightly/monthly report of drought condition is provided to the Government under NADAMS. From the year 2012, the NADAMS project is being implemented by the Mahalanobis National Crop Forecast Centre (MNCFC), Ministry of Agriculture, after the technology was transferred to MNCFC by NRSC.
Agricultural drought assessment with multiple indices as indicated below;
Shortwave Angle Slope Index (SASI)
Normalized Difference Wetness Index
Normalized Difference Vegetation Index
Soil Moisture Index (derived from soil water balance approach)
IMD Rainfall data – rainfall deviation, number of dry weeks
The present report is a summary of agricultural situation during June 2012 for13 states and contains satellite derived vegetation index images, rainfall deviations and assessment of agricultural situation.

Among the various vegetation indices that are now available, Normalized Difference Vegetation Index (NDVI) is most widely used for operational drought assessment because of its simplicity in calculation, easiness in interpretation and also its ability to partially compensate for the effects of atmosphere, illumination geometry etc. Normalised Difference Vegetation Index (NDVI) is derived from (NIR - Red/NIR + Red) where NIR and Red are the reflected radiation in visible and near infrared channels. Various colours in the NDVI image - Yellow through Green to Red - indicate increasing vegetation vigour. The legend of colour bars

and the vegetation index values are provided along with the vegetation index image. Water, clouds and snow have higher reflectance in the visible region and consequently NDVI assumes negative values for these features. Bare soil and rocks exhibit similar reflectance in both visible and near IR regions and the index values are near zero. The NDVI values for vegetation generally range from 0.1 to 0.6, the higher index values being associated with greater green leaf area and biomass

The agricultural crop condition is monitored based on the NDVI information derived from satellite data. The vegetation index images of the country after overlaying the forest area mask and agricultural vegetation condition map for June 2011 and 2010 are shown in Plates.
After precluding the forest area, district wise average vegetation index statistics are generated. The district wise vegetation status during the current season is assessed based on the seasonal NDVI progression.

Shortwave Infrared (SWIR) band is sensitive to moisture available in soil as well as in crop canopy. In the beginning of the cropping season, soil back ground is dominant hence SWIR is sensitive to soil moisture in the top 1-2 cm. As the crop progresses, SWIR becomes sensitive to leaf moisture content. SWIR band provides only surface wetness information. When the crop is grown-up, SWIR response is only from canopy and not from the underlying soil. NDWI using SWIR can complement NDVI for drought assessment particularly in the beginning of the cropping season. NDWI is derived as under;
NDWI = (NIR-SWIR) / (NIR+SWIR)
where Near Infra Red and SWIR are the reflected energy in these two spectral bands. Higher values of NDWI signify more surface wetness.

SASI images were generated using 8-day composites of MODIS 500 m images of NIR, SWIR 1 and SWIR 2 bands. SASI is highly sensitive to rainfall and hence indirectly associated with crop sown area. SASI variations in the season which represent dynamics of surface moisture were used for assessing the Area Favourable for Crop Sowing (AFCS) from time to time. General threshold values of SASI specific to soil texture that indicate favorable situation for crop sowings were identified. Based on SASI thresholds, discrimination of the Area Favourable Crop Sowing (AFCS) was done on weekly basis for each state. The AFCS weekly values are useful to assess the intensity of early season/sowing period agricultural drought

intensity in terms of timeliness in the commencement of sowings, extent of delay or reduction in crop sowings.

The soil water balance (SWB) model is a convenient way of estimating the soil moisture over a large area with considerable reliability. A simple book keeping – bucket type – water tight model was developed to derive the top 30cm profile soil moisture. This model considers the initial root depth of 30 cm throughout the season to capture the soil water scenario for crops sown and germinating during any part of the cropping season. The soil water balance in the upper layer is governed by daily values of rainfall, runoff, evapo-transpiration (ET) and drainage to the second layer. When the upper layer saturates in excess of Field Capacity (FC) due to rainfall, the excess water percolates to the lower passive root zone and are instantaneously redistributed in that zone. The excess soil water in the passive zone moves out as deep percolation. Since the upper 30 cm is considered for the soil water assessment the lower limit of soil water is the residual water content of the soil as the upper layer is exposed to the atmosphere and subjected to upward flux due to the direct solar radiation. The climatic, soil and crop parameter are the main inputs for the SWB. The daily near real time TRMM 3B42RT spatial rainfall product and the daily global potential evapo-transpiration data are used as the rainfall and climatic input, respectively. The soil information was derived from the 1: 0.5 million scale NBSS&LUP soil map. Since this model does not take into account the irrigation applied from various sources, the results of the model should be considered over rainfed areas alone. The Soil Moisture Index (SMI) derived is defined as the proportion of the difference between the current soil moisture and the permanent wilting point to the field capacity and the permanent wilting point. The index values range from 0 to 100 with 0 indicating extreme dry condition and 100 extreme wet conditions.

As per IMD, all India average rainfall upto 27th June 2012, was 108 mm against a normal of 140 mm. There are 24 meteorological subdivisions that have received either scanty or deficit rainfall. Only 12 met. Sub-divisions have received either normal or more than normal rainfall. In 2011, during the corresponding period, only 10 met. Sub-divisions have received either deficit or scanty rainfall and the remaining sub-divisions received normal or excess rainfall. Rainfall deviations from normal at district level, for different weeks of June were depicted in Plates.

With delayed monsoon and its slow progression, rainfall received during June month was deficit in majority of the meteorological sub-divisions affecting the kharif crop sowing activity.
Anomalies of SASI indicated a large proportion of the agricultural area (>50%) in dry
condition in the current season compared to normal monsoon year of 2011 in the states of Bihar, Jharkhand, Orissa, Uttar Pradesh, Tamil Nadu, Karnataka and Haryana. Delay in the onset of monsoon and scanty rains in the current season have reduced the surface wetness, affecting the commencement of kharif agricultural operations.
Soil Moisture Index (SMI) derived from spatial soil water balance model, was very low
upto 30th June, in most parts of the country due to monsoon delay and deficit rainfall. Comparison of SMI between 2012 and 2011 indicated lower SMI values in 2012 in many parts of the country.
The Area Favourable for Crop Sowing (AFCS) has been derived from (1) SASI data
integrated with ground data on cropping pattern, soils and irrigation support and (2) Spatial Soil Water Balance model. AFCS reflects the agricultural area with significant surface wetness and hence favourable for crop sowing activity. AFCS reveals very less favourable area for crop sowing in kharif 2012. Out of 108 M ha of kharif area, only 34 M ha has been found to be under favourable area. In 2011, up to the corresponding period was 49 M ha. The AFCS values are very less in majority states – Madhya Pradesh, Uttar Pradesh, Rajasthan, Gujarat, Bihar and Jharkhand indicating the unfavorable seasonal conditions in June 2012.
Very low NDWI values in most of the states are the result of reduced rainfall and its
poor distribution. More than 50% of agricultural area in majority states shows very large negative deviations from normal NDWI, reflecting the intensity of surface dryness over agricultural areas.
NDVI and its deviations do not indicate the commencement of agricultural activity and
seasonal greenness in majority states particularly in Madhya Pradesh, Uttar Pradesh, Rajasthan, Gujarat, Bihar and Jharkhand states
Multiple indices involving SMI derived from soil water balance, satellite derived SASI,
NDWI and NDVI and their comparisons between 2012 and 2011, IMD rainfall and its derivatives indicate that crop sowing activity has not commenced in many parts of the country upto 30th June. Wide spread meteorological drought over most of the states, involving large proportion of agricultural area, could be observed as a result of slow progression of monsoon and deficit rainfall.

Uttar Pradesh and West Bengal. In other states,
there is significant difference in dryness/wetness
between the two years.
Even in highly irrigated states – Punjab and
Haryana, surface dryness is widespread in 2012.
Increased surface dryness in the current season is
caused by reduced monsoon rainfall
