Like patchwork quilts, satellite views of farming patterns around the world form the above montage of images taken by the Terra satellite.

At top-left, a regular grid pattern suggests that agriculture was shaped by 19th-century surveying in Minnesota. Meanwhile, center-pivot irrigation in Kansas is responsible for the circles visible in the second image. A well in the middle of each field serves as a pivot point for wheeled, spraying watering machines.

In the top-right image of northwest Germany, small and disorganized fields can be traced back to the less-planned farming of the Middle Ages.

Curious pie-shaped fields in the lower-left image are the result of a planned settlement near Santa Cruz, Bolivia. At the center of each field is a village, while a buffer of rain forest separates each community.

In Thailand, at bottom-center, rice paddies just outside Bangkok form skinny slices. The purple fields are flooded, a normal part of rice’s life cycle.

At bottom-right, Brazil’s woodland-savanna cerrado contains massive farms, a by-product of the flat land’s inexpensive price.

Many thanks, NASA and National Geographic.

Threats to animal genetic resources being discussed

DAD-Net, which is hosted by the Animal Genetic Resources Group of FAO, is organizing an e-conference “Analysing threats to domestic animal genetic resources.” It will run 4-25 May and…

…[i]nput from the e-conference will be used to fine tune and finalize a document that will be circulated via DAD-Net, and potentially made available to the Commission on Genetic Resources for Food and Agriculture.

A background document has been circulated and will form the basis of the discussion. It consists of a summary of responses from 107 subscribers from 55 countries to a questionnaire survey to identify threats to animal genetic resources. The headline finding is that by far the main danger to animal genetic resources worldwide are “economic and market driven threats.” Click on the thumbnail below to see the breakdown by agro-ecological zone.

You know, I don’t recall a similar e-conference ever happening for crops. Why not, I wonder? These animal people are so much more Web 2.0. Anyway, I look forward to blogging about the main findings of the discussion when they come out.
