In March, the Meteorological services director David Gikungu said weather drivers show most parts of Kenya will receive depressed rains in the March-May season.
He said these rains are still adequate if farmers plant fast-growing or drought-resistant crops.
“The country is already experiencing drought conditions, particularly in arid and semi-arid counties, due to inadequate rainfall over the last five seasons,” Dr Gikungu said.
