Remember when you were younger, or possibly still now, you’d get that mid-afternoon hunger, reach for a sugary snack, only for a relative to tell you to grab a banana instead? Although perhaps not as tasty, bananas are full of the goodness that we need to function. Among other benefits, bananas contain potassium that keep our hearts strong, vitamin B6 that we need to make oxygen-transporting hemoglobin, fibre for digestion and carbohydrates that give us energy. They also have a high starch content, which provides our bodies with glucose, our main source of fuel. There’s no doubt that they’re an essential food for us, but their Ethiopian relative is a literal life saver. 

The ensete diet 

Imagine a taller, wider banana tree. Except there’s no bananas growing on it, and its trunk can grow to one meter wide. That’s Ensete ventricosum, also known as the ‘false banana’. Ensete only grows in Ethiopia and it’s the main source of starch for Ethiopians. Forget bread, potatoes or rice, ensete is harvested for its starchy pith, which is pulped, fermented and left underground until it resembles a heavy bread, which is then eaten with milk, cheese, cabbage, meat or coffee. “Ensete is the staple food and main source of starch for 20 million people as well as livestock in Ethiopia,” explains Pat Heslop-Harrison, Professor of Plant Cell Biology and Molecular Cytogenetics at the University of Leicester. It’s vitally important for Ethiopians, but farmers who are under pressure to grow this ensete face a big challenge – keeping the plants alive and healthy, free from diseases, and select varieties which will be productive despite climate change. That’s where genetics comes in. 

Changing the farming game 

“In collaboration with Ethiopian and other colleagues, we study the germ plasm from the range of ensete that farmers are growing in Ethiopia, extract the DNA, measure the genetic diversity and match that up with the issues that farmers face growing their crops,” says Pat. “That way, we can select and create modified versions of the crop whose newly-designed genetic makeup makes them invincible to disease and viruses, and can even dissuade insects from damaging the crop.” 

That means farmers can grow more crops that are stronger and healthier, providing a much-welcomed boost to their income and more food to go round in Ethiopia. It’s a win-win situation. 

But it’s not just in Ethiopia where Pat and his international team are changing lives. They’re studying the biodiversity and characteristics of species around the world, including cereals such as oats in Europe and Asia, brassicas such as cabbage, mustard and oilseeds in India, and forage grasses (plants eaten by livestock) in Colombia that will not only make life easier for farmers, but also increase living standards, reducing civil unrest. 

Plant power: winning the war against poverty 

Cattle farming is one of the most widespread agricultural activities in Colombia, with cattle occupying 80% of the country’s agricultural land – that's an average of one cow per 3.5 acres, and a lot of mouths to feed. Traditionally, farmers would move cattle between fields, giving the grass time to regrow and ensuring there’s plenty of food to go round. But in mountainous areas, herding cattle up hill is a tiring, time-consuming exercise and damaging to the environment.
