I imagine there are few sights as breath-taking as the Rift Valley, so on Thursday I was pleased that we stopped for a few minutes on our way to Nakuru. I’m certain I joined the many tourists before me who have stopped at the same vantage point to take a photo or two, but, I’m not in Kenya to be a tourist. Instead my remit is to talk to plant health clinic doctors, based in various locations, about the challenges they face and the development of the Plantwise initiative. That’s exactly what I’ve been doing over the past week, making for a very productive and interesting introduction to Kenya.

Many of us dislike getting older, but you can usually predict how it will go: next year you expect to be 1 year older and you expect your body to be 1 year older. But what if instead of continually growing over a year, your body instead decided to grow for 6 months and then stop altogether until next year?

Shouting out about plant clinics

Plantwise works with in-country agencies to set up plant clinics, which farmers can attend with a sample of their affected crops to obtain a diagnosis and treatment advice. Plant clinics are often run in larger towns or villages, and farmers can travel many miles to talk to a plant doctor to solve their crop problems. So how do farmers find out about where and when the next clinic is running? I asked co-ordinators of plant clinics in Sierra Leone, Uganda and India about how clinics in their countries are advertised to farmers. Read more of this post
