The mother-in-law and the Useful Tree Species for Africa
ICRAF have a nifty new tool out called “Useful Tree Species for Africa.” I’ve been playing around with it and I have to say it’s impressive. Not altogether easy to use, but impressive. If you’re at all into using native trees in Africa — for whatever reason or purpose — you’ll want to explore it. Here’s a taste of what it can do.
You download the kmz files from the ICRAF website and open them in Google Earth. ((BTW, thanks again to Google for the Pro license.)) Then you think of somewhere you’re interested in. In my case, as usual in these situations, I chose the site of the mother-in-law’s spread above Limuru in Kenya. Useful Tree Species for Africa first tells you what sort of vegetation is potentially found there, according to White’s iconic Vegetation Map of Africa.
In this case, it’s “M19a Undifferentiated Afromontane vegetation (viii AMCE)”. What does that mean? Well, there’s a hyperlink which gives you more information on Mapping Unit 19a:
Crucially, this page, which opens in Google Earth, includes more hyperlinks, to four different species tables. Say you are interested in tree species found in this sort of vegetation that can support honey production. You click on the hyperlink labelled “Mapping unit 19a_uses.xls.” That in turn opens an Excel spreadsheet with a list of about 50 tree species and lots of different types of uses. You sort the species on “Bee fodder” and you get a shortlist of about 17 species, from Albizia gummifera to Syzygium guineense. Clicking yet again, this time on the species name, takes you to the PROTA page on the tree, with lots more information. Now, what would be really cool in due course would be a cross-link to ICRAF’s Tree Seed Suppliers Directory, so that you could work out where to get seed of your useful tree.
As I say, nifty. Lots of clicking, and opening of webpages, and of spreadsheets, and of more webpages, but you do end up with the information you want. If your query is place-based rather than species-based, that is. I don’t think the tool will let you start with a useful tree and work out where you can grow it, rather than start with a place and work out what can grow there. But let me play around with it a bit more. Maybe I’m wrong.
Fear not, teachers of FGR, help is at hand!
In response to increasing demand for capacity building on forest genetic resources (FGR), Bioversity has just launched a training manual for forestry practitioners, lecturers, trainers and students to increase understanding of how to manage diverse and complex forest and other tree based ecosystems sustainably. It can be used for teaching and learning about FGR issues both in formal education and on-the-job training.
So we are told, and so we believe, and we’re more than happy to spread the word. The training materials include, among other things, videos on Youtube (see below), and PowerPoint presentations on Slideshare. All that’s missing is a Facebook page and a wiki and the Web 2.0 makeover will be complete. Happy learning — and teaching!
Nibbles: Date palm sex, Heirlooms congress, World Camel Day, Latino livestock, Coconut craft, Hybridizing Alocasia, Sami reindeer, Serbian agri-environments, Honey, Feidherbia
- Qataris work out how to sex date palms.
- The National Heirloom Exposition revs its engine.
- World Camel Day is coming up. No, really.
- Latin Americans planning their next congress on the biodiversity of domestic animals. Cuy, anyone?
- The Art of Coconut Craft. Wonderfully kitschy.
- So, you want to breed Alocasia, do you?
- Sweden stops oppressing its main minority.
- High Nature Value farming in Serbia.
- Non-wood forest products are all very well, but…
- Yes, yes, Feidherbia will solve all the problems of the Sahel, now can I go back to sleep?
Brainfood: Cabbages, Crops in Darfur, Sowing dates, People and biodiversity, Honeybees, Rhizobium, Figs, Urban ag, Wild olives, Ancient textiles, Ducks, Wheat introgression, Food citizenship, Crop models, Trifolium, Variety choice
- Genetic diversity of Brassica oleracea var. capitata gene bank accessions assessed by AFLP. Czech genebank; subgroups reflected place of origin.
- Optimizing the cropping mix in North Darfur State, Sudan. A study of Umkdada district. “…the results of the model were different from the real practices of the farmers.” Oh dear. To improve the fit, schoolboys should work in the fields more. And crops should fetch more. The dismal science indeed.
- Climate-driven simulation of global crop sowing dates. Ok, this model works. You can predict sowing dates under rainfed conditions for various annual crops from climatic conditions. Not entirely sure why you would want to, though.
- Exploring some of the myths of land use change: Can rural to urban migration drive declines in biodiversity? Yes, counter-intuitively, at least in the forests of Mexico’s southwestern highlands. More from Conservation Magazine.
- Pollination services in the UK: How important are honeybees? Quite a bit, but maybe not as much as previously thought. It’s the wild bees, stupid!
- Genetic diversity and symbiotic effectiveness of rhizobia isolated from root nodules of Phaseolus vulgaris L. grown in soils of Iran. It is high, and it varies, respectively.
- Interspecific hybridization of fig (Ficus carica L.) and Ficus erecta Thunb., a source of Ceratocystis canker resistance. It’s a breakthrough!
- Exploring the diversity of urban and peri-urban agricultural systems in Sudano-Sahelian West Africa: An attempt towards a regional typology. There are 6 types. Not 5; not 7. On this one, the journey is more interesting than the destination.
- Variability of wild olives (Olea europaea subsp. europaea var. sylvestris) analyzed by agro-morphological traits and SSR markers. There’s a lot of variabzzzzzzzzzz…
- Hemp in ancient rope and fabric from the Christmas Cave in Israel: Talmudic background and DNA sequence identification. Mainly flax, but some hemp, from both Roman and Chalcolithic periods. But can you smoke it?
- Modelling the distribution of domestic ducks in Monsoon Asia. Low resolution data, plus fancy modelling, can be used to get pretty good high resolution predictions.
- Gene flow between wheat and wild relatives: empirical evidence from Aegilops geniculata, Ae. neglecta and Ae. triuncialis. It happens, a lot.
- Toward food system sustainability through school food system change: Think&EatGreen@School and the making of a community-university research alliance. Food citizenship?
- Simulation of winter wheat yield and its variability in different climates of Europe: A comparison of eight crop growth models. Big differences among models, so best thing to do is to use the mean of all of them.
- The potential of plant viruses to promote genotypic diversity via genotype × environment interactions. The negative effect of White Clover Mosaic Virus (WCMV) infection on performance differs from white clover genotype to genotypes, which means differential selection, which means negative frequency-dependent selection in host populations, which means diversity. Via.
- Amplifying the benefits of agroecology by using the right cultivars. Why should we summarize, when an author has already done so?
