Agrobiodiversity is crops, livestock, foodways, microbes, pollinators, wild relatives …
Jacob has an idea why using climate data won’t always make the haystack smaller:
To me, the potato results mean that we shouldn’t be looking at selection, but at migration and drift. Selection reduces diversity, migration and drift determine where it goes.
I could spend all day reading the blogs of volunteers in different countries. One I keep coming back to is Jessica’s Letter from Niger. It’s an exciting time:
There is a rush to do as much planting as possible before the soil dries out, so families spend all day every day out in the fields, working hard to get all of their millet, sorghum, beans, sesame, and peanuts in the ground. Millet is the priority; once an entire field is planted in millet, people will go back and plant the other crops in the spaces between.
I hope their crops survive and do well.
“This new forage has great insect resistance”, effused a former colleague, “we just need to eliminate the toxins that keep sheep from eating it.”
Genetically engineered drought-tolerant crops are introduced with great fanfare, only to disappear when they turn out to have low yield under nondrought conditions.
Fascinating post from R. Ford Denison, about how silly old natural selection (apparently) fails to make simple changes that would “obviously” be good for the organism concerned. Denison is very clear, in this post and elsewhere on his blog, about just how hard it is for even clever people to improve on the countless experiments that natural selection has had to work on, especially in agriculture. That’s why I for one am not holding my breath waiting for anyone anywhere to transform a C3 plant into a C4 plant.
For years I’ve been seeing it in writing: NBPGR, Pusa Campus, New Delhi. But the picture of it I had in my mind turned out to be quite different to the reality. The Indian Agricultural Research Institute’s Pusa Campus comprises offices, labs and staff housing, yes, but also a huge area of agricultural fields, and right in the middle of New Delhi: a rural oasis in the teeming city (clicking on the map below will take you to Google Maps).
It all started in 1934, when the Imperial Agricultural Research Institute, established in 1905 at Pusa in Bihar, was moved to Delhi following an earthquake. Hence Pusa Campus. The institute of course became the Indian Agricultural Research Institute on independence, just like its parent body, the Imperial Council of Agricultural Research, became the Indian Council of Agricultural Research (ICAR). But many of the buildings are still used. Such as the library.

Nigel on reducing the size of the haystack:
The case of potatoes is very interesting indeed, but is it typical? There are numerous papers showing that using ecogeography as a predictor of patterns of genetic diversity does not always work, but ecogeography is still widely used because in the absence of clear genetic diversity or characterisation/evaluation data there is practically no alternative.
Practically no alternative, or no practical alternative? There is a difference.
