Tesco farmers have been told to plant more crops this year over fears that climate change will spoil more of their harvest.

The supermarket has struck new deals with two of its largest carrot and onion suppliers in a bid to safeguard crops from Britain’s changing weather, The Telegraph reported.

The grocer has lowered its forecasts on how much its farmers will grow per hectare of land and is set to ask suppliers to plant more fields in the hopes their output will stay the same.

The new contracts stem from fears that climate change could trigger more extreme weather patterns, resulting in damages to crop yields.

It comes as the grocery sector experienced several shortages earlier this year after several sharp bursts of heat and frost led to shortages of tomatoes, cucumbers, turnips and more recently, a lack of artichokes.

Tesco is said to have included clauses in the new agreement that it will take extra vegetables if farmers end up with more produce than anticipated.
