单选题 For generations，the Nganyi people of western Kenya have served as rainmarkers，helping local communities decide when best to prepare their land and SOW their seeds.By observing subtle changes in nature that would be unnoticeable to most people--in air currents，the flowering and shedding of leaves of certain trees，the behaviour of ants，bird songs，etc-they have been able to interpret weather patterns and provide valuable advise. 

But the irregular weather patterns brought by climate change mean the rainmaker's can no longer use those signs to make their predictions.And they don't have accDs8 to the technologies available to meteorologists（气象学家）.

“ Climate change‘has come on so fast.People don’t know how to adapt or what.to plant，”says Obedi Osore.a traditional Nganyi weatherman.“0ur traditional crops are disappearing because they cannot handle the new conditions.We need new strategies to handle climate change.”

Now a British Canadian project is doing just that，linking the rainmakers with government meteorologists.The two groups get together each season and produce all agreed forecast to be spread using a variety of methods suited to communities where many cannot read or write-through ceremonies，public meetings and person to person communication. 

Both parties are pleased with the collaboration.“I think the-two,sciences are equally valid.We are marrying our energies to help people better.”says Mr.Onunga，a Nyanyi community elder involved in the project. 

“results have been surprisingly good-the community agreed that the forecast was accurate.”says Gilbert Ouma，a lecturer at the University of Nairobi. 

“Through this project we hope to learn what it is that we can share together to live today and to adopt to tomorrow.”says Professor Laban Ogallo，leader of the Nganyi project. 

Which of the following has been used by traditional Nganyi rainmarkers in weather prediction?
