Identifying plants online

The USDA’s Natural Resources Conservation Service has online (and, indeed, downloadable too), interactive, polyclave identification keys for American grasses and legumes, by state. It’s unclear to me from the introduction whether these cover all grasses in each state, or only the ones which occur in wetlands. In any case, they are for testing purposes only at this stage. But the multi-entry keys are much easier and efficient to use than conventional dichotomous keys. And there are a lot of crop wild relatives included (e.g. see Phaseolus in New Mexico in the screenshot thumbnail below). I don’t think the keys have been build using LUCID (at least I don’t see any reference to it), which seems a bit like re-inventing the wheel, but anyway, better keys are always worth having.

Africa, agriculture and climate change

“If agriculture in developing countries becomes more sustainable, if it increases its productivity and becomes more resilient against the impact of climate change, this should help to reduce the number of currently around one billion hungry people and offer better income and job opportunities,” said Alexander Mueller, FAO Assistant Director-General.

“Millions of poor farmers around the globe could help in reducing greenhouse gas emissions,” said Peter Holmgren, FAO focal point for the UN climate change negotiations. 1

OK. But what about preparing those self-same farmers to cope with climate change by giving them access to agricultural biodiversty?

Africa’s market for milk, meat and staple food crops such as maize, banana, sorghum, rice and millet stands at over $150 billion a year which is more than what it fetches from pet cash crops like coffee, tea and flowers.

Researchers say that seven out of ten Africans earn their living by engaging in subsistence farming making the sub-sector to be the continent’s market leader.

It is for this reason that the farmers are encouraged to embrace modern farming methods to produce more food in order to make economic sense.

On the other hand, governments are obliged to ensure that farm inputs are affordable and farmers have access to markets to sell their harvests at competitive prices to reap fruits of the labour. 2

OK. But does “modern farming” mean abandoning their agrobiodiversity and the skills to use it? And why is it government’s responsibility to make sure inputs are affordable? If government distorts price signals, we can’t blame farmers for doing the most profitable thing in the short term, even if it means losing their agricultural biodiversity and the skills to use it in the longer term.

Featured: unripe fruit

Greenfruit fan (we know who you are) weighs in on Unripe for plucking:

Unripe fruits as food are common in many cultures, including South and Southeast Asia, the Pacific, the Americas and the Caribbean. For their refreshing tartness or light sweetness, or unusual flavor.

The Indian mango problem

What’s going on with mangoes in India? It seems I can’t fire up my feed reader these days without some tale of mango woe popping up. If it’s not Noor Jahan being down to its last four trees, it’s the Kesar variety being cut down in Gujarat. And the Mango Mela — an agricultural fair held in Bangalore — only featured 20 varieties last year, after a really bad, low quality harvest. The latest thing is that Malihabad in Uttar Pradesh has gone from 700 varieties to just a few due to market pressures:

“The reason for certain mango varieties facing extinction threat is the fact that mangoes like Dussheri, Chosa, Lucknowi have taken over the market in a big manner. Mango growers get a good price for these varieties. However, mango varieties that are facing extinction are not able to make their presence felt in the market as there are few trees grown of these varieties,” Haji Kalimullah Khan, a veteran mango cultivator said.

It might be the season, I suppose. There does seem to be a spike of interest in mangoes in March-May. But are things really as bad as all that? Or is the press just focusing on the bad news and ignoring the good, as usual? And if things really are bad, is anything being done about it? Perhaps an expert on Indian mangoes will explain it all to us.
