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.

Kenyan medicinal plant remedies documented

Catching up with some old friends in Nairobi last week I found out that one of them has been involved in preparing a really wonderful “Herbal and Nutritional Guide for Kenyan Families” for an NGO called the Trust for Indigenous Culture and Health. According to its mission statement, TICAH works “to strengthen our understanding of the positive links between cultural belief, practice, and knowledge and the attainment of health.”

Organic agriculture and development

A long article on International Press Service’s wire gives a broad overview of the benefits to farmers in developing countries of switching to organic principles of production. The article cites many benefits, including the buffering and resilience associated with greater diversity in an ecosystem.

For example, a village in the Tigray region of northern Ethiopia that had converted to organic agriculture continued to harvest crops even during a severe drought, while neighbouring villages using conventional chemical fertilisers had nothing, according to Louise Luttikholt, strategic relations manager at the International Federation of Organic Agriculture (IFOAM). Agriculture departments in Ethiopia are reported to be keener on organics now.

The article looks at experiences from elsewhere around the world too.
