- 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: 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.
Nibbles: Breadfruit, Seed Vault, Buckwheat, Rice, Pandanus, Pastoralists
- The beauty of breadfruit. Spoiler alert: resilience.
- The meaning of Svalbard. Spoiler alert: insurance.
- The history of pizzoccheri. Spoiler alert: contested.
- The paddy diversity of Assam. Spoiler alert: in situ.
- The latest NBPGR genebank. Spoiler alert: pandanus.
- The pastoralists of Sardinia. Spoiler alert: flexible.
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?
Brainfood: Convivial conservation, Resilient forests, Traditional industries, Wheat supplies, Food system transformation, Micronutrient security, Biotech promise, Ultra-processed food impacts, Sub-Saharan agriculture, Farmer risk management, Afro-Brazilian agriculture, Biodiversity funding
- Exploring Convivial Conservation in Theory and Practice: Possibilities and Challenges for a Transformative Approach to Biodiversity Conservation. Conservation should be integrative, democratic and redistributive. Hard row to hoe.
- Emerging signals of declining forest resilience under climate change. Convivially or not, better conserve forests quickly.
- Adapting traditional industries to national park management: A conceptual framework and insights from two Chinese cases. Integrative and redistributive, but I’m not sure how democratic.
- Near- to long-term measures to stabilize global wheat supplies and food security. There’s a bunch of stuff that we can do in the short term, but in the end we’re going to need diverse, gender-equitable agro-ecosystems which are properly supported by investment in research. Sort of integrative, democratic and redistributive then, perhaps?
- From food price crisis to an equitable food system. Looks like the food system needs to be as convivial as conservation. If not more so.
- Trade and dietary preferences can determine micronutrient security in the United Kingdom. Going to be difficult to take back control of micronutrient security.
- Turning promise into practice: Crop biotechnology for increasing genetic diversity and climate resilience. Maybe biotech needs to be more convivial too.
- A conceptual framework for understanding the environmental impacts of ultra-processed foods and implications for sustainable food systems. Nothing convivial about ultra-processed foods, alas.
- Why food insecurity persists in sub-Saharan Africa: A review of existing evidence. Exports, basically. Looks like exports are really not very convivial.
- Crops in crises: Shocks shape smallholders’ diversification in rural Ethiopia. Farmers need continual access to both the informal and formal seed systems to mitigate risk, but poor farmers need more money to do so. Maybe link them up to export markets? No, wait…
- Traditional Agriculture and Food Sovereignty: Quilombola Knowledge and Management of Food Crops. Lots of conviviality, but not enough to fully mitigate risk.
- The role of international cooperative initiatives in financing biodiversity. Partnerships between state and a variety of non-state actors may just be an opportunity for more convivial conservation and food systems. But then I would say that.
