- It’s 20 years of the Millennium Seed Bank. Happy birthday!
- CGIAR summarizes 20 years of impact in Ethiopia.
- In 20 years, half of Africa’s coffee land could be gone. Well, 30, but I need to keep this streak going.
- Must have been about 20 years ago that systematic research on African indigenous vegetables really took off, and now look.
Diversify your landscapes redux
I originally published this post on 29 July, but then Dr Baudron pointed to two additional papers on Twitter, and then later to another one, so I’m re-upping, for the second time, with a sixth bullet point.
There’s a nice series of papers on the benefits of diverse landscapes in Ethiopia from Frédéric Baudron of CIMMYT and others.
Just in case this tweet disappears, or whatever, here are the links:
- Wheat yields and zinc content are higher closer to forests because of elevated organic matter in the soil.
- Diets are also more diverse nearer forests.
- Livestock (but not crop) productivity is higher nearer forests, and smallholder systems generally more sustainable.
- Bird diversity benefits from tree cover too, and that provides important ecosystem services to smallholders.
- Even limited reforestation in the surrounding landscape is associated with higher wheat yields in simulations, and you can potentially measure it from space.
- “More people, more trees.”
A little R&R for ecosystems
It seems we missed, back in August, a huge report on CGIAR’s work on ecosystem restoration. After a thorough stocktaking, the report suggests the following are critical for successful restoration:
- secure tenure and use rights
- access to markets (for inputs and outputs) and services
- access to information, knowledge and know-how associated with sustainable and locally adapted land use and land management practices
- awareness of the status of local ecosystem services, often used as a baseline to assess the level of degradation
- high potential for restoration to contribute to global ecosystem services and attract international donors
Which seems sensible. At least if “practices” in 3 and “services” in 4 and 5 include some consideration of genetic diversity. And on that note, it’s also about time we linked to the Royal Botanic Gardens Sydney’s page on Restore & Renew (R&R).
It only covers New South Wales and Victoria, but the R&R Webtool could be something for CGIAR to run with globally. You pick a spot you want to restore, and, for a selection of trees, it tells you where best to source germplasm from. That’s based on current climate, future climate and, crucially, genetic similarity ((But see this for a different view.)) (if data are available).
Of course, this is just the start. Scaling up the supply of tree seeds for landscape restoration remains a major challenge. A recent review, also involving CGIAR scientists, makes quite a few useful recommendations. But in the end, I suspect, it will come down to this:
- put in place incentives and enabling policies to support smallholders in producing, trading and using high-quality genetically diverse reproductive materials
Yes, we have lots of banana news
There’s recently been some interesting banana germplasm collecting in Papua New Guinea. ((No, I don’t mean the Bougainville expedition, do keep up.))
The results are summarized in two articles, one in Plants evaluating methods to ensure the viability of collected seeds, and the other in Crop Science summarizing the characterization of diverse phenotypes.
We’ve included both the papers in question in past Brainfoods, but this press release, from which the above quote is taken, does a really nice job of bringing them together. It might also have added an additional recent paper on the work of the International Musa Germplasm Transit Centre (ITC), but anyway.
There’s a whole bunch of summary statistics on the ITC, and lots of useful links, on the Genebank Platform webpage. And of course Genesys has a selection of accession-level data. But the place for all your banana information needs is ProMusa.
Brainfood: Now what edition
- Image-Based Goat Breed Identification and Localization Using Deep Learning. Fancy maths can identify goat breeds from photos. Ok, cool, now what?
- AI Naturalists Might Hold the Key to Unlocking Biodiversity Data in Social Media Imagery. Fancy math can often identify common flowers on Flickr. Ok, cool, now what?
- FoodMine: Exploring Food Contents in Scientific Literature. Fancy maths can trawl the literature to pick out the chemical components of different foods. Ok, cool, I guess, now what?
- Cultural and linguistic diversities are underappreciated pillars of biodiversity. Well, yeah. But now what?
- Global priority areas for ecosystem restoration. Fancy maths says restoring 15% of converted lands in identified priority areas could avoid 60% of expected extinctions while sequestering 30% of the total CO2 increase in the atmosphere since the Industrial Revolution. Cool, now what?
- An unexpectedly large count of trees in the West African Sahara and Sahel. Wait, does that mean some of the above won’t be necessary?
- Cost and affordability of nutritious diets at retail prices: Evidence from 177 countries. Fancy maths shows that nutritious diets are almost 3 times as expensive as diets supplying basic energy needs, and costs increase with remoteness. Ok, cool, now what?
- Phylogenetic inference enables reconstruction of a long-overlooked outbreak of almond leaf scorch disease (Xylella fastidiosa) in Europe. The olive plague started on almonds. Ok, now what though?
- Genome-wide association study in accessions of the mini-core collection of mungbean (Vigna radiata) from the World Vegetable Gene Bank (Taiwan). Genotyping, phenotyping and fancy maths find that mungbean could grow in temperate conditions. Ok, cool, now what?
- Enhancing the searchability, breeding utility, and efficient management of germplasm accessions in the USDA−ARS rice collection. Genotyping and fancy maths can improve genebank management. Well, yeah, but now what? No, wait, we know exactly now what: digital genebanks!
- Ok, that was a bit of fun, but the important point is that research, no matter how cool, is only the beginning.
