Bolivians going back to their roots
I blogged a couple years ago about what might be called the “1491 controversy,” which hinges on whether you think the Amazon and adjacent areas were densely populated and closely managed before Columbus arrived, or an unproductive, largely pristine wilderness. One of the areas in question is the basin of the Beni River in Bolivia. Whatever your stand on the 1491 debate, it is undeniable that the Beni is a heavily modified landscape.
Shallow floodwaters cover much of the low-lying lands in the Llanos de Moxos during part of the rainy season. The rest of the year, dry conditions prevail and water is scarce. The alternation between seasonal flooding and seasonal drought, combined with poor soil conditions and lack of drainage, make farming in these areas difficult. The ancient inhabitants of the area created an agricultural landscape to solve these problems and make the area highly productive. They constructed a system of raised fields, or large planting surfaces of earth elevated above the seasonally flooded savannas and wetlands. Experiments have shown that the raised fields improve soil conditions and provide localized drainage and the means for water management, nutrient production, and organic recycling.
Well, Bolivian researchers are now suggesting that farmers return to these “camellones,” or raised fields, to harness the seasonal flooding, rather than succumbing to its depredatioons. Oxfam is supporting the project. The BBC was there.
If, as predicted by many experts, the cycles of El Niño/La Niña are going to increase in intensity and frequency, then the project has the capacity to help poor families cope better with the extreme weather events and unpredictable rainfall that are to come.
It would also allow them to cut down on fertilizers, and dabble in aquaculture. There is some scepticism, which has to do with the necessary investment in time and effort. But early results show gains in productivity, apparently, although it’s unclear from the BBC article what exactly is being compared. Anyway, there is much optimism.
This process could be repeated in various parts of the world with similar conditions to the Beni like parts of Bangladesh, India and China.
In the words of local farmer Maira Salas: “We are only just now learning how our ancestors lived and survived.” Well, yes, but with a difference. Some of the crops that are been grown in the camellones are exotic, which is fine, of course. But will there also be a revival of neglected traditional indigenous crops?

No little houses on this prairie
I promised you more on the Doolittle Prairie, and here it is. But first, thanks to Candy Gardner for arranging the visit, and to Mark Widrlechner for leading the tour.
Doolittle Prairie State Preserve, near Story City in Iowa, is a small remnant of native tallgrass prairie. The 26-acre state-owned protected area supports about 220 plant species. 1 About half of the area, the northern part, has never been ploughed or grazed, though hay was cut until the 60s. The southern part has been grazed, and the southwest corner ploughed until 1965 and then replanted with seed from the northern section. All around are fields of maize and soybean. Management is by cutting and burning, to keep down exotics, and encroaching shrubs and trees.
It’s a very evocative place. You can just imagine the deer and the buffalo roaming on it back in the day. There are still deer. Buffalo, not so much. 2 It’s also pretty interesting from an agrobiodiversity perspective, because it’s got quite a number of crop wild relatives for such a small place.
A couple of species of wild sunflowers, for example. This one is Helianthus rigidus:
There are also native species of Allium, Elymus, Lactuca, Fragaria, Prunus, Ribes, Rubus, and Vitis:
All in a beautifully colorful setting, at least at this time of the year.
So, a bit of a CWR hotspot, in its own small way, and protected to boot. You may remember the recent global review of the role of protected areas in CWR conservation. I don’t think that CWR have been mapped in the US in the same way as has been done in Russia, however. 3 Once you have geo-referenced CWR locations, you could easily mash the result up with the online map of protected areas to see which national parks and reserves contribute most to CWR conservation. Anybody out there working on this? I bet little Doolittle Prairie would be on that list.
“We have very little data”
That’s Javier de la Torre talking about ecological niche modeling at GeoWeb. Well, I would qualify that by saying we have too little digitized data. Certainly for many crop wild relatives, for example. Javier was involved in a recent online mashup of the global protected area database. His GeoWeb slides are below, catch his talk on YouTube.
