Cocoa from tree to cup

News from both ends of the cacao value chain today. At the upstream end, new molecular marker work on over a thousand genebank accessions reveals that the species is divided into no less than 10 genetic clusters, rather than the conventionally recognized two. These show a clear geographic pattern: they are strung out along an east-west axis in the Amazon, probably reflecting, according to the authors, the location of ancient ridges (“palaeoarches”), which were barriers to dispersal not only for Theobroma but also for various fish groups. Meanwhile, at the downstream end, there’s an account of a visit to a “chocoholic mecca” in Santa Fe.

LATER. And, for the trifecta, news from somewhere around the middle of the value chain.

LATER STILL. What comes after trifecta?

Searching for seeds?

Mother Earth News has an online seed finder. It lets you search the “online catalogs of more than 500 mail order seed companies,” mainly in the US, presumably. Test it out and let them know if you could or couldn’t find what you were looking for. We might need to send them our seed list

Technology is not enough

Greater investment in improving agricultural technology certainly needs to be part of the solution to meet the rising demand for food. But if spatially connective infrastructure (roads and bridges in particular) and complementary services such as agricultural extension are ignored, these findings from Bangladesh suggest that few farmers in lagging but potentially productive regions will benefit, thwarting the goal of raising agricultural productivity.
