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.

UNESCO World Heritage Sites and agricultural biodiversity

Two of the newly-inscribed sites in the UNESCO World Heritage List caught my eye because of their agricultural biodiversity connections: both, interestingly, are in Europe. The first is the Lavaux vineyard terraces, 30 km of 1000-year-old agricultural landscape around Lake Geneva. The second is the primeval beech forest of the Carpathians, in Slovakia and Ukraine. However, I must admit that this second one only caught me eye by mistake, as it were. I thought it was in these forests that the last aurochs lived, but that was ignorance, pure ignorance on my part. It is the wisent that lives there, still. The last recorded aurochs died in 1627 in the royal forest of Jaktorow in Masovia, central Poland. Somewhere else entirely. But I wonder if there are any other wild relatives — of either livestock or crops — in the primeval Carpathian beech forest.

Bamboo galore

The latest issue of FAO’s NWFP-Digest seems to be joining in with the celebrations of the 10th birthday of the International Network for Bamboo and Rattan (INBAR). In addition to the International Bamboo & Rattan Expo in Guangzhou, China (see map), it points to a new technique from India for rapid bamboo propagation, the manufacture of bamboo bicycles in Ghana, the sale of bamboo socks in the UK and the planting of bamboo in Bhutan. There’s lots of other stuff too, though.

Rescuing the American chestnut

You know, these Nibbles (the short, soundbite-type things which appear at the top of the right sidebar of this page) are fun to do, but sometimes you end up downplaying, or over-simplifying, an important, interesting — and interestingly complex — story. Take what I said about the American chestnut a few days ago. The recent history of Castanea dentata is proud and tragic ((Looking further back, it also played an important role in native America agroforestry.)), and efforts to bring it back from the brink of annihilation well-nigh heroic. To imply, as I did, that these efforts were confined to hybridizing the American with the Chinese chestnut was justified only by the necessity for extreme brevity. In fact, of course, it is not just hybridization but repeated back-crossing. And not just interspecific crossing but also painstaking crossing among the few remaining pure American chestnuts, as reported in the article that prompted me to revisit the original story and hopefully make amends for my earlier flippancy.
