Calling Colorado State University locals

Rebecca Nelson, who researches improving disease resistance in crops, will be the speaker at the ninth annual Thornton-Massa Lecture at Colorado State University at 7:30 p.m. Monday, Oct. 13, in the Lory Student Center Theatre. Her topic is “Science vs. Hunger: The Challenges of Funding Research in International Agriculture,” and it would be great to get a report here.

A landscape to marvel at

That image took my breath away when I saw it a couple of days ago. It shows rice terraces north of Pokhara, Nepal. The caption to the picture said that the economy of Nepal is based on agriculture,

“which employs 80 percent of the working population and accounts for 41 percent of the gross domestic product of one of the world’s poorest countries. Generations of farmers have tamed the mountainsides and prevented erosion by cutting terraces. Rice paddies thus rise in tiers as high as 9,800 feet (3,000 m) above sea level, covering 45 percent of Nepal’s cultivated land.”

The photo was one of almost 40 at a wonderful site called The Big Picture at boston.com. Two or three times a week Alan Taylor assembles a portfolio of outstanding photographs from around the world. This time they were by Yann Arthus-Bertrand, who has developed a wonderful technique of photographing nature and humanity from the air.

Many of the pictures that The Big Picture showcased depended for much of their impact on agriculture, and the patterns that human interference creates on the ground. This particular one caught my eye for two reasons. First off, it is very, very beautiful. Secondly, Pokhara is a famous name among some agrobiodiversity nuts (such as myself). I’ll explain in a minute. So, I made a note to come back and blog the story here when I had a moment. Imagine my horror, then, when I headed over to The Big Picture and found this note:

At the request of the coordinator of Yann Arthus-Bertrand’s upcoming exhibit, the number of photographs displayed here has been reduced to ten.

Pokhara had vanished. Yikes! That’ll teach me to procrastinate. But, knowing as I do the Dark Side of the Web, I simply assumed that someone, somewhere, would already have stolen it, and I was right. Lock, stock and barrel, the entire sequence of 38 images had been scraped by a nefarious site (to which I will naturally not link). They’d even had the gall to put their own credit on the image, a matter of minutes to excise. So, saved, by evil. ((It is, of course, not Evil to do exactly the same thing and steal back the photo for Good.))

Which brings me to the importance of Pokhara. The farmers there have been working with a local NGO called LI-BIRD and with Bioversity International to develop a local landrace of rice. After a concerted effort to find and then assess hundreds of versions of the landrace, the farmers came up with an improved version that was eventually registered with the Nepalese authorities as a “proper” variety that can be sold. That may not sound like much of an achievement, but take it from me: it is. But I had never seen the agricultural landscape in which this work was undertaken. Now that I’ve seen Arthus-Bertrand’s picture, I’m even more impressed.

You can read about Pokhareli Jethobudho at the web site of Bioversity International and at the International Development Research Centre in Canada, one of the donors that supported the project.

Resistance (to UG99) is futile

The Pakistan Biotechnology Information Centre has good news to share:

LAHORE: The scientists of Ayub Agricultural Research Institute, Faisalabad has successfully developed a new variety of wheat ‘UG99’ which is resistant to stem rust disease of wheat. The disease poses world-wide threat to wheat productivity and productive approach of AARI scientists to solve this problem would prove highly beneficial for the country.

Unfortunately, no more details are forthcoming. Where did they find the resistance? How did they get it into a productive variety? The world needs to know.

Disappearing wild potatoes mined for drought tolerance

An article in National Geographic looks at possible changes in the climate of the Andes, how they will affect potatoes, and what breeders are doing about it. The wild relatives are very much to the fore:

“The crosses we are developing between wild, drought-tolerant varieties and modern potatoes now are for the future,” said Meredith Bonierbale, senior potato breeder at the International Potato Center in Lima.

The article also quotes our friend, colleague and occasional contributor Andy Jarvis, ((Andy works for CIAT and Bioversity in Cali, Colombia.)) who recently collaborated with others on a paper which concluded that some of those very same wild relatives are themselves threatened:

“Even if we halt habitat loss, in the next 50 years, climate change could undo all of the conservation that we already have,” said Jarvis.
