- Consistent stabilizing effects of plant diversity across spatial scales and climatic gradients. More species-diverse communities are more stable. Ok, what about agricultural systems though?
- Financial profitability of diversified farming systems: A global meta-analysis. Total costs, gross income and profits were higher in diversified systems, and benefit-cost ratio similar to simplified systems. No word on stability, alas.
- Global systematic review with meta-analysis reveals yield advantage of legume-based rotations and its drivers. Integrating a legume into your low-diversity/low-input cereal system can boost main crop yields by 20%. I wonder if this meta-analysis was included in the above meta-analysis. Again, no word on stability though.
- The influence of food environments on dietary behaviour and nutrition in Southeast Asia: A systematic scoping review. It’s the affordability, stupid. Should have gone for more diversified farming I guess :)
- Global food systems transitions have enabled affordable diets but had less favourable outcomes for nutrition, environmental health, inclusion and equity. Well according to this, industrialised farming (ie simplification) has led to more affordable diets. But we know from the above that diversification can be profitable. So it was the wrong kind of simplification? Can we diversify now and maintain affordability while also improving nutrition, environmental health, inclusion and equity? Wouldn’t that be something.
- Disentangling the numbers behind agriculture-driven tropical deforestation. Ending deforestation is not enough. The resulting agriculture must be diversified in the right way too, I guess.
- Strategizing research and development investments in climate change adaptation for root, tuber and banana crops in the African Great Lakes Region: A spatial prioritisation and targeting framework. Diversifying with drought-tolerant bananas and heat-tolerant potatoes is all well and good, but you also have to know where exactly to diversify, and here’s how.
- Translational research in agriculture. Can we do it better? Difficulty developing drought-tolerant bananas and heat-tolerant potatoes? Get more diverse peer-reviewers.
- Increasing crop field size does not consistently exacerbate insect pest problems. When you diversify, don’t worry too much about making fields bigger.
- Genetic diversity loss in the Anthropocene. You can predict change in genetic diversity from change in range size, and the average is about a 10% loss already. Ok, what about agricultural systems though? Wait, isn’t this where we came in? My brain hurts…
Nibbles: Ghana genebank, Indian crop breeding, Bhutan genebank, Grafting, Vielfalt auf Feldern und Tellern
- Genebank pushes Bambara groundnut in Ghana.
- Acharya NG Ranga Agricultural University develops new varieties, deposits them in Indian genebank.
- Bhutan’s national genebank explains its work.
- Grafting fruit trees in India to save them.
- All of the above contribute to SDG 2.5.
- All of the above are needed to get out of the food and climate crises. How? Crop Trust executive directors explains for German speakers.
Nibbles: Old olive, Silphion, Heirloom watermelon, Calabrian chili, ICARDA genebank, Jamaica genebank, Tamil community seedbank, Forestry seeds
- Really old olive tree in the gardens of the mosque-cathedral of Cordoba is a lost variety.
- Long extinct medicinal spice plant not extinct after all?
- The next nearly extinct heirloom on our list is a watermelon from Virginia. Who knows, it may originally have been grown in Cordoba or Cyrenaica…
- And moving in the opposite direction, a really hot Calabrian chili pepper beats the heat.
- The ICARDA genebank is trying to find stuff that will beat the heat too.
- Jamaica is looking to beat the heat by establishing some new genebanks.
- Tamil Nadu going the community seedbank route, and why not? Jamaica please take note.
- An alliance of forestry outfits is pushing for a global seedbank infrastructure to support woodland restoration. Nothing if not ambitious. And much needed.
Plant Treaty Parties finally party in person
After almost three years, the Ninth Session of the Governing Body of the International Treaty on Plant Genetic Resources for Food and Agriculture will finally meet physically again next week, in New Delhi. I’ll be there, and may be able to tweet and blog, depending on the rules. But for sure the great people at Earth Negotiations Bulletin will be there putting out their very perceptive daily digests.
Nibbles: Food security, CWR, Rice, Food crisis, Yams, Peanuts, Tuscan wine, SADC seeds, Lonely trees
- Handy primer on the effects of climate change and biodiversity on food security, courtesy of the House of Lords.
- Crop wild relatives could help with all three.
- Trouble brewing for rice. House of Lords nodding wisely.
- The trouble that brewed for wheat wasn’t quite as advertised. Spoiler alert: the price spike had to do with China buying up all it could. So is rice next then?
- No trouble brewing for yams now that they’re getting sequenced.
- Nor for peanuts in the Gambia, for different reasons.
- Sounds like everything is hunky dory for the Tuscan grape too.
- Good to see SADC is on the job.
- It may be too late for some trees though.
