CIRAD, the French agriculture research organisation, reports on efforts to make cocoa a more sustainable crop. Using a network that spanned 35 institutes in five African countries, the researchers studied cropping systems, participatory breeding (especially for pest and disease resistance), soil fertility and plant health. Results appear to be encouraging, especially growing the cocoa trees under a shade canopy and interplanting with other high-value crops. Both techniques improve local biodiversity and give farmers additional sources of income.
Ocean’s prairies dying
A press release from University of California at Davis says that seagrasses, which deliver considerable ecosystem services, are vanishing, but because they are generally out of sight they are also out of mind. Susan Williams, a UC Davis marine biologist, is one author of a report on the plight of seagrasses in the journal BioScience; unfortunately the journal is behind a subscription wall, so I cannot tell you more.
Business opportunities in biodiversity
A blog called Conservation Finance draws attention to a report on building biodiversity businesses. The report was prepared by the World Conservation Union (IUCN) and is a draft for discussion, but I cannot do that as I have not yet read it. However, I noted with pleasure that there is a section on agriculture, which is encouraging, and not all that common among mainstream conservationists. By the way, Conservation Finance’s link to the report is pretty much broken; use this one instead.
Fermenting the biofuel revolution
Part 2 of my musings on bioenergy is now available. This ramble looks at a novel form of breeding yeast, persuading it to make many more errors as it copies its DNA, and thus throw up lots of mutants for engineers to select among. The result is a yeast of unparalleled potency that would have been all but impossible to produce by tinkering with one gene at a time. And that leads into a consideration of some of the policy aspects of biofuels, such as what poor people will eat when the bioenergy industry is paying more than double today’s price for food in order to turn that food into fuel.
DNA database of fungal biodiversity
Scientists at the University of California at Berkeley are working with samples from the Venice Museum of Natural History to create a DNA database of some 6000 different species. A press release from UC Berkeley gives more details of the project, which will zero in on a small portion of non-coding ribosomal DNA that is known to be unique to each species. The database will allow researchers to identify fungi conclusively without having to wait for them to fruit, an erratic process that can be subject to delays. This could help scientists to respond more rapidly to the global spread of some fungal pathogens. It will also be useful for taxonomic studies.
