Talks were held between Russia and Turkey on a UN plan to restart Ukrainian grain exports. Western countries have accused Russia of risking global famine by shutting Ukraine's Black Sea ports. Arnaud Petit is executive director of inter-governmental group the International Grains Council, and discusses the challenges involved in getting Ukraine's grain supplies moving again. Also in the programme, the UN's World Food Programme is working with the California ride-hailing app Uber to use its technology to help move emergency supplies of food and water within Ukraine. The BBC's Zoe Kleinman explains how the software might help lower the risk of delivery trucks becoming targets, by enabling supplies to be moved around in much smaller vehicles. Plans for compulsory quotas for women in senior positions have been agreed by the European Parliament and EU member states. A third of all directors in companies employing more than 250 people will need to be women within the next four years. We find out more from Lara Wolters, who is a Dutch socialist member of the European Parliament, and who also led negotiations on the change. Plus, the BBC's Vivienne Nunis reports on concerns around oil development in the Congo basin which may threaten peatland storing 30bn tonnes of Carbon Dioxide.

Today's edition is presented by Mike Johnson, and produced by Nisha Patel, Elizabeth Hotson and Gabriele Shaw.
