Global warming means continental crops could take root in Britain by 2030

A report by the Department for Environment, Food and Rural Affairs (Defra), suggests there could be unexpected benefits to climate change with exotic fruits and vegetables thriving.

But native species, such as potatoes could suffers as average temperatures rise by around 2C by 2030.

Experts predict that within two decades, southerly counties like Devon and Cornwall will be warm enough to support dates, a staple of the Middle East as well as chickpeas. figs, aubergines, peppers and chillies.

"Farmers won't abandon old crops, but at the same time UK agriculture can seize the opportunity to grow new crops. I want British farming to produce as much as possible," said Environment Secretary Hilary Benn.

Rice, usually imported from Thailand, China and the Philippines could become a staple crop for British farmers while the south coast could even support olive and apricot trees.

The change could also help tackle the growing obesity problem in Britain. A Mediterranean diet is renowned for its health benefits and longevity.

Lavender fields, which are currently blooming in East Anglia, could also become a common sight throughout the rest of the country as summers become longer and drier.

British vineyards are also expected to flourish in the next 20 years, with varieties like Pinot Noir and Tempranillo, varieties usually associated with the south Mediterranean, becoming commonplace.

However warmer temperatures could also bring new pests such as wheat rust, a fungus which causes crops to disintegrate, and the Colorado beetle, which attacks potatoes.

And the supply of water is expected to drop by 15 per cent with English rivers losing 20 per cent of their volume in the summer months.

The Commons environment, food and rural affairs committee is expected to call for Britain to increase domestic food production to avoid food shortages and soaring prices by 2050.

The Defra report will be published in August.
