This Autumn everybody will feel the pain of rapidly increasing food prices, and poor countries may face food riots and growing malnutrition. Winter feed on Irish farms is also at worryingly low levels.
Ear to the Ground presenters Darragh McCullough, Helen Carroll and Ella McSweeney will be investigating these stories, and more, throughout this 20th series, and talking to the local heroes who will have to cope with, and overcome many difficulties.
Stories being covered during this brand new series include Darragh joining a 'fodder run' where a group of volunteers transports fodder to less fortunate farmers in another part of the country.
Helen is part of the self-sufficiency craze that is transfixing urban dwellers - hens in the back garden are her latest subject for investigation.
Sporting heroes who love the land are always in Ear to the Ground's sights.
Also later in this 20th series of Ear to the Ground, Ella spends a long day with a champion jockey, down on his farm as well as at the races, giving viewers a rare insight into the life and controversies of one of Ireland's exceptional sportsmen.
Ear to the Ground is produced by Independent Pictures for RTÉ.
