That it has absolutely nothing to do with agriculture! That’s the only conclusion to be drawn from a report on the CABI blog about a study in the journal Biological Conservation. It reports a survey of “the general public” in the Cairngorm Mountains in Scotland, which tried to discover what they knew about biodiversity. (I’ve pinched my headline direct from them.) You might think the Cairngorms are not a very agricultural place, but you would be wrong. There’s a great deal of farming up there, to say nothing of timber industries. And some of the conservation efforts seek to duplicate farming practices that have fallen by the wayside. But to hear CABI tell it, even though the survey included foresters and “farmer students” there seemed to be almost no understanding of how agricultural practices are part and parcel of landscapes and their ecology. Bah!
One up, one down
Following on from Luigi’s post a month or so back about the probable return of the chestnut to American woods, two stories, on consecutive days, from the Christian Science Monitor. One gives more information about the complex breeding programme that involves Chinese chestnuts, resistant American trees and lots of painstaking crosses to produce blight-resistant chestnuts. That work has been going on since the early 1980s, and may now be close to complete. A few days earlier, the paper reported on the threat to the Eastern Hemlock, a woolly bug, originally from East Asia. Adelges tsugae has been slowly spreading across the US, where the only hope seems to be a decent cold winter. The fear is that the Eastern Hemlock will go the same way as the Carolina Hemlock, which once shared the forests with the American chestnut and which, experts fear, could now be eaten out of existence.
Small forest enterprises are big
From IIED, a report on the International Conference on Community Forest Management and Enterprises, held in Acre, Brazil in mid July. Most of the item is about IIED’s own contribution, about small forest enterprises, which are more dependent on, and better for, forest biodiversity. But there is a summary of conference outcomes and links to fuller reports and other useful organizations.
Tree domestication a huge success
There’s a heart-warming tale over at the Rural Poverty Portal (nice site, too) of the International Fund for Agricultural Development. A tree domestication project in west Africa has brought higher incomes and improved status for women, which has translated into schooling and better nutrition. Women are running their own tree nurseries, selecting which species to grow and nurturing them for market. So far the number of species is limited, perhaps that will improve. The project was implemented by the World Agroforestry Centre.
Cacao and conservation
A whole issue of the journal Biodiversity and Conservation looks at how cocoa production landscapes can contribute to biodiversity conservation. There are several papers on specific case studies and also an overview. Most of the discussion is — predictably — about what cacao cultivation can do for biodiversity, but, what about the other way around? The overview does suggest that
it is important to understand trade-offs between productivity and conservation and the economic costs of conservation friendly practices to land users so that more effective policies can be designed… Quantifying the benefits (both short and long-term) of biodiversity within agroforestry landscapes to farm productivity, for example via pest and disease control … requires attention.
What are these biodiversity-friendly practices? Here’s a few ideas, again from the overview:
- eco-friendly certification
- research and extension to increase productivity while maintaining diverse tree canopies
- development of markets for non-cocoa products
- payment for environmental services
As far as certification is concerned, the Fair Tracing Project may suggest solutions:
The Fair Tracing project believes that attaching tracing technology to Fair Trade products sourced in developing countries will enhance the value of such goods to consumers in the developed world seeking to make ethical purchasing choices.
I’ve just come across this project, and I don’t know much about it. A piece on its web site — basically a blog — about the ICT being used to trace fair trade coffee in Haiti did point me to a rather interesting example of a corporation trying to bridge the digital divide.
