Spring is in the air…

…and a young man’s thoughts naturally turn to gardens. Honduran gardens and their role in health. Cuban organic gardens. And via them, Around the World in 80 Gardens, a BBC documentary series that looks like it might be worth getting on DVD. And, finally, let us not forget Kew Gardens, 250 years old this year.

LATER: And there’s also an extensive discussion of the role of homegardens in providing nutrition for people living with HIV at the Solution Exchange for the Food and Nutrition Security Community in India. Thanks, Arwen.

LATER STILL: LEISA rounds up evidence of the worldwide gardening craze.

Visionary carp farming

The Ecologist has nominated its “10 visionaries with 10 big ideas for a better world.” The full article is behind a paywall, but the names are there, and Jimmie Hepburn gets the nod in agriculture.

That was a new name on me, but he and his wife Penny turn out to have become celebrities of a sort in the UK for running an organic aquaculture business in Devon.

“There’s great interest in the fish,” said Jimmie. “The truth is that we have forgotten how to eat fish like carp. In medieval times they were very popular. Now they are usually grown to huge proportions for anglers who take a photo of them and throw them back. Hardly anyone thinks of them as food.”

Congratulations to the Hepburns.

Land sharing or sparing?

That is one of the questions addressed by a paper in Journal of Applied Ecology which looks at the ecogeographic distribution of organic farming in the UK. “Land sparing” means excluding land from intensive agriculture to protect biodiversity. “Land sharing” is a contrasting strategy which would make all agricultural land better for biodiversity. The study recommends

…continuing to use intensive agriculture to meet our food production targets, but using organic farms in suitable areas to provide islands of biodiversity, as well as a smaller amount of food.

So the vote is for land sparing. Ok, fair enough. What gets me, though, is that, as usual, it is only the effect of agriculture on the surrounding wild biodiversity that is being considered. What about the biodiversity that is an integral part of the agricultural system itself? Doesn’t agrobiodiversity count for something in all this?
