- 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…
Happy birthday to Aussie genebank guidelines
The Australian Network for Plant Conservation is celebrating the first birthday of the third edition of “Strategies and guidelines for developing, managing and utilising ex situ collections” with a nice bunch of resources. And a quick survey. Check it out.
Brainfood: GIAHS, Austronesian ag, Neolithic Scotland, Livestock origins, Iroquoia maize, Maya drought, Agave diversity, Coffee diversity, Breadfruit cultivation
- Agricultural heritage systems and agrobiodiversity. FAO’s Globally Important Agricultural Heritage Systems (GIAHS) work just fine.
- A northern Chinese origin of Austronesian agriculture: new evidence on traditional Formosan cereals. The precursors of the Austronesians took foxtail millet, broomcorn millet and rice to Taiwan from around Shandong in northeastern China in the second half of the 4th millennium BCE. That was quite a globally important agricultural heritage system (note lower case) in its day.
- Neolithic culinary traditions revealed by cereal, milk and meat lipids in pottery from Scottish crannogs. At roughly the same time as the above, farmers in Scotland were eating a gruel made of wheat and milk. Maybe not so globally important, but still.
- Epipalaeolithic animal tending to Neolithic herding at Abu Hureyra, Syria (12,800–7,800 calBP): Deciphering dung spherulites. That wheat and milk came from far away and long ago. In fact, maybe 2000 years longer ago than is usually thought.
- Tracing Maize History in Northern Iroquoia Through Radiocarbon Date Summed Probability Distributions. Maize really took off in NY/Ontario/Quebec between 1200 and 1450 AD.
- Drought-Induced Civil Conflict Among the Ancient Maya. Towards the end of the above period there was real strife in the Maya lands, but also local resilience. Makes you wonder whether whatever was happening among the Iroquois and Maya was somehow connected.
- Genomic and Morphological Differentiation of Spirit Producing Agave angustifolia Traditional Landraces Cultivated in Jalisco, Mexico. Whatever happened in Mesoamerica 600 years ago, Indigenous knowledge of agave diversity survived.
- Vernacular Names and Genetics of Cultivated Coffee (Coffea arabica) in Yemen. Indigenous knowledge of coffee diversity doesn’t correspond with genetic data in this globally significant agricultural heritage system.
- Advanced and emerging agricultural innovations for securing food, climate and ecosystems in Moroccan oasis. Even globally important agricultural heritage systems need innovation.
- Potential of breadfruit cultivation to contribute to climate-resilient low latitude food systems. Breadfruit can be important globally, not just in its current agricultural heritage system.
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.
Brainfood: Seed boundaries, Open Source Seeds, Chickpea evaluation, Central Asia homegardens, Teff evaluation, Wheat collection rationalization, Resurgent millets, Duplicates software, Cooking up “minor” crops
- Constructing Seed Boundaries: Foundation and Evolution of Scientific Conceptions and Practices of Crop Diversity from the Green Revolution to date. We need to put the knowledge, expertise, activities and needs of farmers at the centre of conservation and use of crop diversity.
- Open Source Seeds and the Revitalization of Local Knowledge. Open-source seeds is one way we can put the knowledge, expertise, activities and needs of farmers at the centre of conservation and use of crop diversity.
- Evaluation of Global Composite Collection Reveals Agronomically Superior Germplasm Accessions for Chickpea Improvement. We need detailed, multi-location, multi-year agronomic evaluation of chickpea diversity to figure out what diversity we should use to give farmers the diversity we think they will need.
- Home gardens of Central Asia: Reservoirs of diversity of fruit and nut tree species. We need homegardens.
- Data-driven, participatory characterization of farmer varieties discloses teff breeding potential under current and future climates. We need detailed, multi-location, multi-year agronomic evaluation of teff diversity done in collaboration with farmers to figure out what diversity we should use to give farmers the diversity they will need, and what they already have.
- Cultural Effects on Sorghum Varieties Grown, Traits Preferred, and Seed Management Practices in Northern Ethiopia. We need detailed, multi-location, multi-year studies of farmers’ sorghum diversity, practices and needs to figure out what diversity we should use to give farmers the diversity they will need, and what they already have.
- Metrics for optimum allocation of resources on the composition and characterization of crop collections: The CIMMYT wheat collection as a proof of concept. We could use genotyping and this fancy maths to figure out what to have in our wheat genebank collections so we can then figure out which diversity to use to give farmers the diversity we think they will need.
- From marginalized to miracle: critical bioregionalism, jungle farming and the move to millets in Karnataka, India. Forget wheat. We need local food activism. But critical local food activism.
- G-DIRT: a web server for identification and removal of duplicate germplasms based on identity-by-state analysis using single nucleotide polymorphism genotyping data. We need this fancy software to get rid of duplicates from our genebank collections so it’s cheaper to maintain them and ensure that they’re always around for people to use to get to farmers the diversity they need.
- “Famine Foods” and the Values of Biodiversity Preservation in Israel-Palestine. We need recipes.
