The World Urban Forum is taking place down in my home town this week. That I suppose was what provided at least part of the impetus for the United Nations Standing Committee on Nutrition (UNSCN) to issue a statement on the Nutrition Security of Urban Populations. Not to be outdone, FAO has a publication out too, Growing Greener Cities in Africa, touted as the “first status report on urban and peri-urban horticulture in Africa.” A cursory glance doesn’t reveal much on diversity in these documents, but this is an issue that’s always intrigued me. Could cities act as magnets for crop inter- and intraspecific diversity? After all, they have lots of micro-niches, and have been attracting people from all over for decades, who could have come with their seeds. Is it possible that varieties could still be grown in cities after they’ve disappeared in their native areas? Or at any rate that crop diversity in a city is higher than in the surrounding countryside? Sometime ago we did a small survey of sweet potato diversity in Nairobi roadside verges that seemed to suggest that the menu of varieties was at least somewhat different from what was available in nearby rural areas. Should write that up one day. Anybody know of similar studies?
Nibbles: Community gardens, Malnutrition in Peru, Good nutrition and longevity, Efficient conservation.
- A film about community gardens in the city of Washington DC.
- “Ricos en agrobiodiversidad, pero pobres en nutrición.” Huancavelica, in Peru, has plenty of agricultural biodiversity and plenty of malnutrition. Go figure.
- Good nutrition is more important than reduced calories for longevity, in rhesus monkeys at least.
- Conservation magazine reports that return on investment is the best guide to economically-efficient conservation. We ask … well, you know what we ask, right?

- Where do seedless watermelons come from? In a here-and-now sense.
- A long and fascinating read about gardens and war and much besides.
Nibbles: Deforestation, Mayan collapse, Agroforestry, One Acre Fund, School gardens
- Cutting down forests worsened ancient Mayan droughts.
- And (among other things) did for the Maya.
- And despite the Mayan end of the world being near, the French are revitalising agroforestry.
- The Financial Times wrote about One Acre Fund’s work to reduce agrobiodiversity in Kenya, then put it behind a paywall (for me). So One Acre Fund sprung it.
- School gardens continue to flourish in some places.
