According to this article, the number of date palms in Morocco has declined from 15 million at the end of the 19th century to 4.5 million now, mainly due to desertification. That has to have had some effect on genetic diversity, and I’m willing to bet there are data out there on the numbers of varieties at different times in the past.

This has been a recurring theme for ages, but is still worth noting in case anyone can make use of the information. Officials have high hopes that “if the research proves successful in using the flowering plants and the biomass energy crops to remove pollution from farmland, it will not only able to help raise farmers’ incomes, but also encourage the reuse of polluted farmland, promote agricultural transformation and save water resources”.

For a truly parochial account of one American professor’s dream of diversifying French nut culture, head on over here. A 77-year old retired professor of physics is promoting pecans in Provence.

Urban agriculture, and an appreciation of the myriad benefits of biodiversity, could be a great way to create a common cause between the rich and the poor, but few people make the connections. How hard would it be to twin farmers’ markets across the globe?
