Samuel Ikua is championing urban farming in his city, Nairobi in Kenya.   Samuel undertook an urban farming course in 2015, run by a local NGO called the Mazingira Institute. Seven years later Samuel is the project coordinator at the institute, training other members of his community in urban farming skills.  In this programme Ruth Alexander hears about the challenges Samuel faces, a lack of space and land, and local attitudes to farming in a big city.   Samuel’s commitment to food security in Nairobi saw him chosen by a panel of international judges as the winner of The Food Chain Global Youth Champion Award 2022.

Cows emit greenhouse gases when they eat, which contributes to global warming. But is it possible to produce meat in a climate-friendly way?    Grace Livingstone visits a carbon neutral certified ranch in Uruguay, where farm manager Sebastian Olaso shows her around. She also meets Javier Secadas, a small farmer who raises cattle on natural grasslands, and agronomist Ignacio Paparamborda, from the University of the Republic in Montevideo. Grace hears from Pete Smith, Professor of Soils and Global Change at the University of Aberdeen, and Dominik Wisser, Livestock Policy Officer, from the United Nations’ Food and Agriculture Organisation.   She tries to find out if it is possible to produce meat in a way that is both good for nature and the climate. Or whether we need to stop eating meat to cut emissions.

Can beef be carbon neutral?

Why eat with your hands?  Many food cultures around the world eat using hands, and most of us use our hands some of the time.  Do we really need cutlery or chopsticks to eat a salad, peas or rice? And if you were to tackle soup or stew with your hands, how would you go about it?  Michael Kaloki reports from Nairobi, Kenya, where the staple dish ugali, made from maize flour, is traditionally eaten by hand. Michael has observed that people increasingly use cutlery to eat the dish, and he speaks to restaurateurs and customers about why that might be, and what might be lost.   Ruth Alexander learns about the etiquette of eating by hand with food writer and consultant Karen Anand in India. And Ruth explores whether food might be more enjoyable, and even taste better, when eaten by hand. Psychologist Professor Charles Spence from Oxford University, and chef Jozef Youssef of Kitchen Theory in the UK share their research.

Eat with your hands

Stunning cakes, colourful salads and intricate garnishes use flowers to entice customers, but there’s more to this trend than just beautiful social media pictures.   Many cultures around the world have eaten flowers for centuries, and some of them pack a serious punch.   Devina Gupta explores the history of edible flowers and visits a site in the UK where they’re grown all year round. She gets quite a shock when trying one particular variety.   We find out why flowers are used on food nowadays, and how generations of knowledge about their use and properties were lost when they were brought to Western countries.

Can I eat this flower?

Do you know how much salt you should be eating?   And if I tell you it’s less than 5 grams a day, do you know how much that is?  Ruth Alexander explores the wonder of salt and why chefs think their job would be pointless without it and why the impact it’s having on the food might surprise you.   Professor Paul Breslin tells us about the “magical” chemical reaction happening on your tongue when you eat salt, and why your brain responds to that.   We hear about what eating too much salt can do to you from an expert in Australia, as well as a mother in Kazakhstan who cut out salt almost completely – in a country which has one of the highest consumptions in the world.

To salt or not to salt?

Over two million people work in the international shipping trade, and they are often at sea for months at a time.   That’s a lot of meals being made by the cook on board, and their work is crucial for keeping the crew happy.  Ruth Alexander hears from seafarers about why that makes “cookie” the most important person on board a ship and why, in some cases, crew members are going hungry.    A former captain of merchant vessels tells us how food is used for so-called “facilitation payments” to corrupt officials, and why crews can sometimes be powerless to stop port officials filling up suitcases with food from the ship’s stores.  We also hear about international efforts to try to tackle corruption in ports and increase welfare standards for seafarers.
