OSLO - African farmers are finding new ways to cope with droughts, erosion and other ravages of climate change but need to develop even more techniques to thrive in an increasingly uncertain environment, scientists said on Friday.

Smallholders have started to plant more drought-resistant and faster-growing crops to keep the harvests coming in, according to a survey of 700 households in Kenya, Ethiopia, Uganda and Tanzania.

"The good news is that a lot of farmers are making changes," said Patti Kristjanson, who heads a program on climate change, agriculture and food security at the World Agroforestry Centre in Nairobi and led the study.

"So it's not all doom and gloom ... but much more needs to be done," she told Reuters.
