Food security is one of the pressing issues on the agenda at the COP27 summit in Egypt, as developing countries have to find ways to adapt to the effects of climate change on agriculture.

In Kenya, the government prepares to commercialise genetically modified maize seeds early next year. But there is resistance from some farmers and campaign groups, who question their safety.

The seeds will be planted on half-a-million acres and will be drought resistant, the country's agricultural authority says, thus helping curb shortages caused by the lack of rain.

Kenya is currently facing a severe water shortage caused by four failed consecutive rainy seasons, amid one of the harshest droughts the East African region has seen in four decades. This means crops are not able to grow, prompting warnings of potential famine.
