Tech companies have developed drones to drop pollen on orchards or shoot it at crops through pipes from tractors. They’re responding to a crisis in insect pollination as studies suggest numbers of both wild pollinators and farmed bees are declining. This could have a serious knock-on effect on how we grow our fruit and veg. But some experts argue high-tech alternatives are a short-term solution to a much bigger and long-term problem.

New technology is helping in the fight against wildlife poaching. Computer scientists have created a programme that uses artificial intelligence to predict where poachers are going to strike; a new generation of smart cameras is catching the criminals red-handed; and the latest police forensic techniques are being adapted to investigate these crimes. The aim is to put a stop to the illegal trade of wildlife trafficking, which is worth billions of dollars and is threatening the survival of species such as elephants, rhinos and tigers. Each year 20,000 elephants are killed for their ivory, according to WWF estimates. Reporter and producer - Richard Kenny for BBC World Service

A short online test that reveals attitudes, opinions and thought processes is being used to help decide whether to give people loans. The idea is to use psychometric tests to give people with little or no credit history a better chance of getting support and investment. New ways of providing financial services are needed because 1.7 billion people have no access to any kind of formal banking facilities, according to the World Bank. Known as the unbanked, they deal only in cash. This can make it harder to reduce poverty, save money or invest for the future. Cheap mobile phones and good network coverage in Nigeria are also transforming the lives of people who previously only dealt in cash.
