Small farms produce more food than statistics show

Recording the true production levels of small farms could help farmers access greater support, according to researchers.

Small farms sometimes get overlooked as a feasible solution for feeding a growing population, but researchers say they should be given greater support, with some producing more food than official statistics report. While small farms can play an important role in supporting rural economies, many owners struggle to earn a decent living which can lead … Read more

Transforming the dirty water we flush down the drain into new products, such as clean energy and fertilisers, can help prevent reservoirs from running dry and change the way this valuable resource is viewed. Currently, water use risks leaving half the world facing severe scarcity by 2030 as demand outstrips supply. The linear way our societies … Read more

In a picture: How this robotic tendril mimics climbing plants – Dr Barbara Mazzolai

Plants move at a much slower rate than what we can see. They don’t have muscles so they’ve figured out different ways to move. One way is through osmosis, which shifts water in their stems to change their stiffness. What you see in the video is a robot actually using osmosis. This is very important … Read more

The genetics and ageing rate of elephants could hold clues to helping us find better ways to fight cancer and lead healthier, longer lives. In 2015, 1.3 million people died from cancer in the EU, more than one quarter of the total number of deaths across the 28 nations. Despite cancer treatment improving in recent years, the … Read more

Every year 7 million hectares of forest are cut down, chipping away at the 485 gigatonnes of carbon dioxide (CO2) stored in trees around the world, but low-cost drones and new satellite imaging could soon protect these carbon stocks and help developing countries get paid for protecting their trees. ‘If you can measure the biomass you can … Read more
