More than three billion people, most of whom are in developing countries, rely on the ocean to make a living. Fisheries and aquaculture provide the main source of animal protein for some 17% of the world’s population. In the least-developed countries, fish contributes about 29% of animal protein intake.
Consumers can support small fisheries by supporting local enterprises, increasing income for small fisheries. By supporting artisanal fishing (traditional or subsistence fishing) they can also contribute to improving livelihoods, boosting nutrition, and strengthening food systems, but fishers’ input is needed locally, nationally, and globally.
A UP-led team is using the momentum of light to trap particles. This optical trap has been used with collaborators to demonstrate a hidden property in light that remains unchanged even when it passes through turbulence.
A breakthrough study from the University of Pretoria has found that small hive beetles trapped inside a honeybee nest sneakily entice the very bees that keep them prisoner into providing them with the best of what there is to feed on in the hive – even some of the queen’s portion.
Small hive beetles (Aethina tumida) sometimes invade nests to feed on pollen and honey stores, and to lay eggs. So African honeybee subspecies herd the tiny insects into inaccessible cracks and corners of the nest where they can cause no harm. The beetles then dupe the bees that keep them prisoner into providing them with the best food in the hive.
Can the government communicate more effectively with people to encourage them to contribute more to initiatives such as the Solidarity Fund? By better understanding the factors that will nudge citizens into action, it can.
Research from the University of Pretoria shows that South Africans are more willing to contribute to a cause if they believe that their donation will have a greater impact on society. In this episode we learn how the generosity of South Africans impacts on our lives.
A study led by researchers at the University of Pretoria (UP) has found that people who believe that others are complying with COVID-19 regulations are more likely to comply as well.
Dr Nicky Nicholls and Dr Eleni Yitbarek of UP’s Department of Economics studied beliefs and behavioural preferences as predictors of compliance with regulations aimed at reducing the transmission of COVID-19 in South Africa. Watch this short video to learn more.
