Surrounded by tall, spindly trees in Central Kenya’s Uplands Forest, Margret Njoki and her daughter dig up a row of potatoes, their hands moving rhythmically in time with one another.
Along with the plot Ms Njoki cultivates at home in the nearby town of Lari, Kiambu County this quarter acre (0.1 hectares) of forest land she leases from the government means she can double her yield of kale and potatoes.
