Sahar Zand reports on the adverse impact of locusts across Kenya and neighbouring countries, which are devouring crops and threatening millions with starvation. Filmed before the UK went into lockdown, she visits Kenya, on the trail of immense swarms of the insects - the biggest for 70 years. In a country in which agriculture provides a livelihood for more than 80 per cent of the population and where over a million people live on the edge of hunger, even a small swarm can eat the same amount of food in a day as 35,000 people, threatening millions with starvation and economic collapse.
