- 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.
Brainfood: Organic tradeoffs, Yield gap, Genebank impact, Rice in Madagascar, Trees & diets, Trees & food system, Global tree diversity, Restoration & emissions
- Biodiversity and yield trade‐offs for organic farming. Switch to organic agriculture if the surrounding land that will need to be converted to farming to make up for production shortfalls is less than 2.4 times more biodiverse than the farmed land. But that’s an average that will depend on the crop.
- Global wheat production could benefit from closing the genetic yield gap. Customize improved wheat varieties to local conditions by using the diversity in genebanks. No word on whether that includes organic conditions.
- The impact of the international rice genebank (IRG) on rice farming in Bangladesh. Someone mention genebanks? 1% increase in genebank contribution to new variety means 1% increase in yield. No word on what happens under organic conditions.
- Constraints on Rice Cultivation in Eastern Madagascar: Which Factors Matter to Smallholders, and Which Influence Food Security? Does swidden cultivation count as organic?
- What are the links between tree-based farming and dietary quality for rural households? A review of emerging evidence in low- and middle-income countries. It’s generally a good idea to keep trees around your farm. But how to make sure that it happens?
- Transforming food systems with trees and forests. Here’s how: scale up tree food production, reorient research towards trees foods, repurposing production incentives towards tree foods, and integrate nutrition with conservation. Got it? No word on whether the whole thing needs to be organic though.
- High exposure of global tree diversity to human pressure. But what about the diversity of trees on farms? Well I guess if we do the above properly it will be ok.
- Carbon removals from nature restoration are no substitute for steep emission reductions. Trees are not enough.
