- 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…
Brainfood: Species mixtures double, Crop diversification, Local adaptation, Speed of adaptation, Essential Biodiversity Variables, Effective population size, Monitoring diversity
- Drought-exposure history increases complementarity between plant species in response to a subsequent drought. Repeated stress makes plant species get along better, sustaining diversity. If only it worked so well with people…
- A quantitative synthesis of soil microbial effects on plant species coexistence. Meta-analysis shows soil microbes work against plant species getting along better.
- Does crop diversification lead to climate-related resilience? Improving the theory through insights on practice. Crops getting along well together is pretty well linked to better livelihoods, but less strongly to increased resilience.
- Local Adaptation: Causal Agents of Selection and Adaptive Trait Divergence. You need to do reciprocal transplant experiments really well to find out where plants are best adapted and why. Probably means taking microbes into account.
- Genetic variance in fitness indicates rapid contemporary adaptive evolution in wild animals. Natural selection can be quicker than climate change. I hope they did the reciprocal transplant experiments really well.
- Global genetic diversity status and trends: towards a suite of Essential Biodiversity Variables (EBVs) for genetic composition. Genetic diversity, Genetic differentiation, Inbreeding, and Effective Population Size (Ne). Who needs reciprocal transplant experiments?
- On the feasibility of estimating contemporary effective population size (Ne) for genetic conservation and monitoring of forest trees. Ouch.
- Selecting species and populations for monitoring of genetic diversity. All of them, right?
Nibbles: Asian yams, Coconut survey, Belarus genebank, Jordan genebank, Tepary beans breeding, Dante’s wine
- Nice Twitter thread on Asian yams (and incidentally sweet potato and taro).
- Surveying and collecting coconuts in PNG. What will they do with those nuts?
- Belarus genebank gets a high-level visit. Can’t help wondering if the Ukraine genebank being in the news is behind this somehow.
- Jordan to get a(nother) genebank. Apparently.
- Tepary beans to get their 15 minutes of fame.
- Medieval Italian wine was biodynamic.
Nibbles: Organic ag, Local ag, Pigeonpea, African cereals, Vanilla genebank, Ag R&D, Ziziphus
- Blaming organic agriculture for Sri Lanka’s woes is a little…simplistic.
- Deriding food localism as luddite is a little…simplistic. I wonder if there will be a rural re-exodus in Sri Lanka.
- Pigeonpea is back on the menu in Malawi. Organically produced, no doubt.
- Will it be closely followed by sorghum and millet in Zimbabwe?
- Brazil puts together a vanilla collection. Because you can only go so far on sorghum and pigeonpea.
- Meanwhile, “…China Has Become the World’s Largest Funder of Agricultural R&D,” displacing the US. Including local and organic ag, pigeonpea and sorghum? I wonder…
- Looks like jujube might be an example of US-China collaboration on ag research. Maybe.
Nibbles: Algal genebank, Baking, Distilling, Ft Collins genebank, Community genebanks, Trinidad genebank, Agriculture & climate change, Nigerian coconuts, Organic agriculture
- Saving an algal germplasm collection in the US.
- Saving ancient grains via baking in Israel and distilling in Minnesota.
- Saving seeds (and more) in a famous genebank in Ft Collins, Colorado.
- Saving seeds in community genebanks in Nepal.
- Saving seeds for the community in Trinidad & Tobago.
- Saving agriculture from climate change in Hainan. Someone tell India.
- Saving the Nigerian coconut sector.
- Saving organic agriculture from politicians.
