One major change which I think could help in the future is the way in which agricultural commodity prices have become linked to cost of oil. The long-term trend in commodity prices until recently was always in decline. As a result - in general - urban dwellers got their food at relatively cheap prices and commercial food production was a mug's game defended as being "a way of life". Now (at last) there is therefore a change in the economic balance between urban and rural in the latter's favour. This should provide better prospects for rural youth to stay in agriculture and to sustain family farming.
