While the number of people in permanent employment by agricultural businesses was slightly lower than the 2010 figure, seasonal employment grew by 36 percent. Both figures indicate adverse changes in terms of declining retention capacities for both the agricultural sector and the countryside as a whole along with the number of people who can only find work on a seasonal basis and thus become increasingly vulnerable. 31 per cent of farmers are aged over 65, whereas the rate of those under 35 is a bare 6.1 percent – being a clear indicator of an aging agricultural population and unfavourable changes in the age structure. In 2013, nearly 3 percent of farmer were college or university graduates, and more than 7 per had received relevant vocational education at the secondary level. Nevertheless, the vast majority (nearly four fifths) are still only relying on their practical experience.
