The Impact of Weather and Climate Risks on Cereal Crops Productivity

Abstract

Increase the intensity and frequency of the weather and climate risks contribute to compromised harvests in recent decades. Analysis of financial losses indicates that in 2007 and 2012 substantial values were reached. In this context it is important to know their regional peculiarities of manifestation both in present and in the years to come. The results shows that pronounced manifestation of the weather and climate risks in recent years (2000-2013) contributed to the decline of winter wheat harvest of 2q / ha compared with the harvest that is expected in the 2020s - calculated according to the most drastic SRES B2A scenario. The results are extremely necessary to take adaptation measures to new climatic conditions and to food security for the future in the Republic of Moldova.
