Given the amount of land occupied by farmers and farming, you might be forgiven for thinking that ecologists would at least pay it more than lip service. But no. A press release from Brown University in the US announces the establishment of the first secretariat for the International Long Term Ecological Research (ILTER) network. It explains the vital importance of long term studies in ecology, to determine trends that may well be invisible over shorter periods. And it explains the various ways in which ecosystems change over time. But does it mention agriculture or changes in agricultural biodiversity? Of course not.
Expert witness
I think WWF came up with a really powerful idea with their “climate witnesses.” These are ordinary people around the world who WWF has asked to act as spokespeople, a kind of warning system for climate change, and advocates for action. One is an old Kikuyu cattle-keeper, who spoke up at the recent climate change conference in Nairobi about the changes he has been experiencing. Makes me wonder if we in the agrobiodiversity community could link up with WWF and use this existing network to highlight specifically how climate change is affecting crops and crop wild relatives. Or do we perhaps need “genetic erosion witnesses” of our own?
Let them eat pizza
A French “prince” has turned his castle into a Conservatoire National de la Tomate. He recommends Seeds of Diversity, with its database of 19,000 cultivars of vegetables, fruit, grains, flowers and herbs, as a source of heirloom tomato seeds.
Wet Wet Wet
The GlobWetland project uses remote sensing and GIS to address the threats faced by the world’s wetlands. Do we know how many crop wild relatives are found in wetlands? Or even how threats to wetlands affect genetic diversity in adjacent agricultural areas? I think plant genetic resources people and the ecosystem conservation crowd need to link up a bit more, and I can’t help thinking that wetlands might be pretty good meeting ground.
Hotspots backlash?
The latest Nature has a paper on mapping endangered animal species in a couple of different groups and relating what might be called “extinction threat hotspots” to “biodiversity hotspots.” The paper is getting a lot of media attention, for example here and here. Perhaps not surprisingly, the two types of hotspots do not match up, so a focus solely on protecting biodiversity in the well-known global hotspots is perhaps not going to be as effective as one might wish. No word on whether someone is doing similar work on plants, but I wouldn’t be at all surprised if the results were to turn out similar. But what about crops? I can think up theoretical arguments why centres of genetic diversity of crops might also be at particular risk from genetic erosion, but as for empirical data the problem is that information on genetic erosion tends to be anecdotal and patchy.
