Mapping agriculture in Bhutan

Great to hear about a national atlas of natural resources, including agriculture, for Bhutan. Such publications are not as common as one might think, alas, but I can’t think of anything more useful in planning agricultural biodiversity conservation activities in a country.

Bats to the rescue

The other Economist article I wanted to mention deals with bats and how useful they are to agriculture, as pollinators (e.g. Agave) and – the main point of the piece – as predators of agricultural pests. Work in Texas is actually trying to quantify the benefit that bats bring to famers of cotton and other crops as they munch their way through moth populations in their millions. Always good to be able to put $ values on biodiversity.

Is climate change an opportunity for Africa?

Kennedy Omenda is a freelance journalist who has written a very interesting article over at The African Executive. Africa’s Agriculture Can Adapt to Climate Change suggests that forecast changes to rainfall patterns, temperature and the like could actually offer Africa a chance for development. Omenda refers to farmers changing their crops and methods and people changing their diets, and benefits that will arise from increased trade and other structural improvements.

It is not a “bad” change after all, but a good opportunity for farmers to embrace new technologies and researchers to brainstorm on products that will suit the various climate patterns. Adequate infrastructure, access to markets and credit will enhance agricultural development and food security while building resilience to future climate change.

I am not absolutely persuaded, I have to admit. Maybe necessity will drive the changes needed, but, to take one example, while farmers in currently wet regions will need to grow crops that can grow with less water, what will farmers in currently dry regions, some of which are going to dryer, grow?

Fascinating aside: Africa “has about 1,150 world weather watch stations. That is one per 26,000 square kilometers—or eight times lower than the minimum density recommended by the World Meteorological Organization”. Maybe climate change will boost investment in weather forecasting that will be directed to farmers rather than pilots and soldiers.

On balance, I think the article is a sort of pro-business-as-usual, but I’d love to hear contrary views.

Where the buffalo roam

There are about 300,000 American bison left. How many of them are genetically pure? I don’t know about you, but I would have guessed many more than the 10,000 quoted in this article. The vast majority have some cattle genes, it turns out, due to past hybridization efforts by ranchers. The largest “un-contaminated” herd is in the Yellowstone National Park. Scientists are doing DNA studies across the range of the species to develop a management strategy. There are plans to reconstitute large tracts of the prairies, and pure bison are needed to roam them. But my question is: how many cattle herds have buffalo genes?

Micropropagating sweet potatoes

According to the Carolina, USA farmer featured in this article, “micropropagation is the name of the game in sweet potatoes.” “The bottom line is a very uniform crop,” he adds. That’s not necessarily everywhere a good thing, of course, but clean planting material is always important.
