Food groups Herta as well as French food co-operatives d'Aucy and Les Paysans de Rougeline are also part of the project that will help producers upgrade their farming, livestock rearing and crop-growing practices.

The partners will help fund an initial 10 million euros (9 million pounds) worth of projects, with the goal of reaching 100 million euros within four years after other partners join.

Carrefour, Europe's largest food retailer, has increased its focus on organic food, under a global five-year plan to boost sales and profits. It has also adopted blockchain ledger technology to track and trace chicken, eggs and tomatoes as they travel from farms to stores.

Under the plan, Carrefour is targeting 5 billion euros in organic food sales by 2022, compared to 1.2 billion generated in 2017. It generated 1.8 billion euros in organic food in 2018, CEO Alexandre Bompard disclosed last week.

Danone is the world's biggest yoghurt company and its CEO Emmanuel Faber has said he wants Danone to play a central role in the new trends sweeping the global food industry. Faber is also a member of Carrefour's food advisory committee.
