Some studies will focus on waste — one-third of all food is thrown out in the Netherlands, Mr. Koster said. On a tour of the restaurant’s many secrets, he pointed out a storage tank beneath the lawn. Kitchen waste will be kept and taken to a farm, he said, to be mixed with animal dung to produce biogas.

But earthworm taxonomists don’t have it so easy. One has to dig for earthworms, and even though they are blind and deaf, worms are remarkably good at evading the probes and shovels of nosy scientists. There’s also the problem of knowing where to dig. An ornithologist can simply meander through a forest and look up; an oligochaetologist must keep an ear to the ground, so to speak, and try to divine the ideal earthworm habitat.
