1 - Introduction

MARS Food-Sec bulletin 01/2010 is the first covering the 2009-2010 summer cropping season (October 2009 to April 2010). The main analysis refers to the time period October to December 2009. To put the current situation in a more general context, some additional data from the previous winter cropping season is included, as well as a general overview of the entire year 2009. For the analysis, data at 10- daily (dekadal) and monthly time steps was used.

The meteo and vegetation conditions of the current growing season are compared to the historical long term average (LTA). The LTA has been calculated over the past 10 years for the SPOT VGT data set at 1 km resolution (vegetation conditions) and the ECMWF data at 0.25? resolution (meteo conditions). The main variables presented are (cumulated) precipitation and air temperature from ECMWF and NDVI derived from SPOT. For producing the maps, two land cover maps have been considered: GLC2000 and GlobCover. The union of both maps (crop land & pastures) masks the displayed pixels.

As for the previous reports, the bulletin starts in Chapter 2 with a general overview. Both, NDVI and meteo data are presented. In Chapter 3 it follows a country specific analysis, where the most important cropping areas, as well as potentially food insecure areas, are highlighted. The reader is also referred to the Annex for more specific details regarding the monitoring regions and spatial crop distributions.

The most striking feature of this growing season is the persistent drought (> 12 months) heavily affectting (parts of) Argentina. This contrasts strongly with the good growing conditions in the most productive parts of Brazil. It is worth noting that the potentially food insecure areas of Brazil need further attention if the dryness in this area persists.
