Brussels, 11 August 2006

Updated crop yield forecasts for 2006 and analysis of drought effects

This Memorandum provides additional information, maps and graphs related to IP/06/1097 on the forecast of cereal production and the impacts of drought. During the agricultural season, the Commission’s Directorate General Joint Research Centre (DG JRC) regularly issues forecasts for the main crop yields and produces analyses of the impact of weather conditions on crop production. These are based on advanced methodologies using satellite remote sensing and mathematical models which simulate crop growth.

The models and methodology in use have been conceived, experimentally developed and operationally implemented within DG JRC.

The crop yield forecasts, analyses and full description of the methodology are available at: http://agrifish.jrc.it/marsstat/.

Analysis of crop yield by crop type and Country

Total Wheat (soft and durum varieties)

The yield is expected to be 3% lower than last year; the resulting EU production could be decreased by about 4.3 Mt. In 2005, wheat production reached a record level. The decrease of production, compared with the average of the last 5 years, is forecast at 1.4 Mt. Thanks to an early maturation, durum wheat (except Italy) production is higher than 2005. Therefore, the total wheat production deficit is attributable solely to soft wheat, which shows the highest decrease in Poland (13.4% lower than previous year and 0.7 Mt less production), UK (-9.0% as compared to 2005 and a reduction around 1.5 Mt), France (-3% compared to 2005, with 0.9 Mt of reduction) and Germany (-1.8% as compared to 2005 with 0.5 Mt of reduction).

Total Barley (including winter and spring varieties):

At EU level, barley yields are expected to remain almost unchanged compared to 2005, though it is reduced by 4.6% if compared to the last 5-year average (equivalent to a production decrease of 3.5 Mt).

The significant reductions estimated in Germany (-5.6% compared to 2005), Poland (-9.6% compared to 2005 and 0.4 Mt), Latvia (-36.0% and 0.3 Mt), UK (-4.5% and 0.2 Mt) and Czech Republic (-8.7% compared to 2005) were compensated by the good harvest in Spain (+48.7% compared to the extremely low 2005 yield but -14.6% compared to 5-year average).

Grain Maize

At EU level, for the time being the yield decrease in grain maize is estimated at 5.1% compared to 2005. This deficit combined with an area decrease will result in a lower production of at least 3.9 Mt. However, the impact on irrigation reserves in some of the main productive basins of the EU (south-west France and northern Italy) could cause further reductions if not enough rainfall occurs in the coming weeks.

Rice: European rice production is forecast to be about 7% lower with respect both to the 5-year average and to the last campaign. This reduction is mainly due to a generalised decrease of the rice cultivated area (around -20% compared to 2005 for Spain, -5% for France, -5% for Greece, -1% for Italy) rather than a decrease in the yields. Portugal is the only European country showing a completely different trend (about +10% for the surface and +11.1% for the yield compared to last year). In some regions, rainfall in the coming days will be needed to avoid damage to crops.

Other crops: the remaining crops are, to a lesser extent, affected or potentially affected by a shortage of rain and water reserves. At EU25 level, rape seed yield is forecast at 2.2% less than 2005, sunflower at -0.5%, potato at -4.3% and sugar beet at -3%.

Forage (grassland and green fodder crops)

Dry conditions in May, worsening in June and July, affected permanent forage areas (pastures and grassland) as well as green forage and green maize in most of Europe. The impact was particularly significant in France, the Baltic countries and Spain. A strong impact was also felt in northern Germany and the Danube Valley but in these areas the situation was eased by precipitation in mid June and July. A strong impact on green fodder and green maize was also felt in the cultivated areas and especially in central France and in the Padana Valley in Italy. Even though some limited areas are severely affected, the overall situation is not as severe as in 2003.
It is still too early to estimate the overall reduction in the available biomass but, if a measure can be given based on the deficit in rainfall, in central France this was over 40% compared to the long term average and over 50% compared to 2003. In the Padana Valley, the reduction was less marked though still a significant -30% compared to 2003.
