First input from

Russian Academy of Sciences’

Space Research Institute

to GEOGLAM Expert Panel Discussion on Drought 2012

slide2

Some preliminary notes

  • The analysis has involved the MODIS data derived NDVI time series for the period of years 2000-2012
  • The maps (next slides) are indicating relative (%) departure of NDVI seasonal maximum for year 2012 from multi-annual average of NDVI seasonal maximums for period 2000-2011. The NDVI seasonal profiles for each year have been also averaged at the level of administrative districts considering available MODIS derived thematic masks, such as
    • arable land mask (for Russia and neighbouring countries)
    • winter crops and spring crops masks (for Russia only)

Some preliminary notes

The map legend is as follows:

red – worse than normal above 30%

pink – worse than normal in range 10% - 30%

grey – around normal +/- 10%

light-green – better than normal in range 10% - 30%

green – better than normal above 30%

white – out of assessment

Based on the available data (combined use of both satellite data derived products and historical agricultural statistics) IKI have published by the end of July 2012 the assessment of the crop yield for Russia considering both winter kill and summer drought factors, which is estimated around 74 mln tons.

Contacts

The analysis has been performed by the Russian Academy of Sciences’ Space Research Institute using VEGA Service Technology (http://vega.smislab.ru/)
