The Food Chain

It’s the world’s most consumed vegetable oil, used for everything from frying food to making it last longer – but can palm oil be produced in a way that doesn't wreak enormous environmental and human damage? In conjunction with another BBC World Service programme, Crowd Science, we visit the Sabah region of Malaysian Borneo, where different groups are working together to change the way palm oil is produced. Presenter Graihagh Jackson hears about a certification system aimed at raising standards on smallholders, reducing the industry’s impact on biodiversity, and boosting incomes. And she speaks to an organisation fighting for the rights of indigenous communities against land-hungry palm oil companies. Plus, what can consumers do to affect change in the industry? We hear how it's sometimes difficult to know whether products contain sustainable palm oil or not. For more on the steps being taken to lessen palm oil's environmental impact listen to Crowd Science: Should I stop eating palm oil? (Picture: A man harvesting palm oil. Credit Getty/BBC)

Running a bakery is hard work - you’re up all night mixing, kneading, proving and baking, and then when the sun rises you need to actually sell your bread and run the business. It’s physically demanding too - repetitive strain injuries to hands are not uncommon. So who’d be willing to put themselves through it? Emily Thomas meets three artisan bakers from different continents to find out what drives them, and why they think most of us have been eating bread all wrong: Islam Sabry, who runs Cairo's Baker, in Egypt; Lee Utsumi, of Lee's Bread, just outside Tokyo, Japan; and Seth Gabrielse, co-owner of Automne Boulangerie in Montreal, Canada. Plus, what happens to your waistline when you're surrounded by freshly baked bread and pastries all day? (Picture: Islam Sabry, Seth Gabrielse and Lee Utsumi.

The food industry has a big problem with packaging, but what if you could simply eat your wrapper or coffee cup instead of throwing it away? Could packaging made from food ingredients prevent our oceans and landfill sites from being clogged with waste, much of it plastic? Could it still preserve and protect our food from damage or spoiling? And does it taste any good? Emily Thomas speaks to two companies developing edible products - one producing plates, cups and bowls, the other making a protective coating for fruit -to find out whether edible packaging is really a clever solution to some serious environmental problems, or just a marketing gimmick. And a food futurologist explains why we're all likely to see more food-based packaging on our supermarket shelves, and how that could change the way we eat and shop.

How dangerous is your takeaway? If you ever order food through an online delivery service like UberEats, DoorDash, or Deliveroo, you probably think only about the meal that will soon will arrive at your door - will it arrive quickly, and piping hot? You possibly don’t think much about the person delivering it, let alone whether they have put themselves at risk in getting it to you. These companies allow customers to order food from a range of restaurants, and then provide a delivery service - by assigning jobs to drivers who are usually self-employed. Across the world, their popularity is soaring. But one hidden aspect of their growth is the dangers faced by their growing legions of delivery drivers, from road accidents, to intimidation, to violence. The Food Chain has seen dozens of reports from all over the world, and spoken to numerous people who work with these companies, all suggesting that the safety of takeaway delivery drivers, needs closer scrutiny. Emily Thomas investigates what it is about food delivery in particular that can be so dangerous - and whether enough is being done to keep these drivers safe.

Across the world, as fruits ripen, teams of pickers set out across the fields. Without them, produce would be left to rot and farms profits would plummet. But in many countries, population shifts and changes to immigration laws have left farmers struggling to find enough people to do the work. The effect has been particularly pronounced in the US where President Trump has cracked down on immigration, and the UK with its plans to leave the EU. Enter the robots. Over the past few years, interest and investment in machines that can pick fruit and vegetables that are usually harvested by humans, have been ramping up. Emily Thomas asks whether we should welcome these new developments. Picking fruit is low paid, low-skilled and physically demanding work, and exploitation in the industry is well-documented. But it’s also a source of income that many depend on, and the main source of employment in some parts of the world. Plus, if we do let machines do the job, what are the implications for the environment, and how our food looks and tastes? (Picture: Man reaches forward to pick an apple from a tree.
