- Contributions of biodiversity to the sustainable intensification of food production. They are various and considerable, but context-specific. See additional data here. See also everything below…
- Development of interspecific hybrids between Solanum lycopersicum L. and S. sisymbriifolium Lam. via embryo calli. Tertiary genepool? No problem.
- The Role of Diet in Resilience and Vulnerability to Climate Change among Early Agricultural Communities in the Maya Lowlands. More diverse diets allowed Maya to survive the droughts of the Late Pre-Classic Period (AD 100–300) better than those of the Terminal Classic Period (AD 750–1000).
- Global restoration opportunities in tropical rainforest landscapes. Massive mashing up of spatial datasets concludes that top 10% areas for potential return of benefits and feasibility of forest restoration are located largely within conservation hotspots and in countries committed to the Bonn Challenge, but cover only a small portion of the Key Biodiversity Area network.
- Plant domestication disrupts biodiversity effects across major crop types. Wild relatives are better at living in diverse mixtures than their descendant crops.
- Synchronous crop failures and climate-forced production variability. ENSO has caused global crop failures. Which are likely to get more frequent.
- Frankincense in peril. Because of cows and fire.
- Identification of Loci Controlling Adaptation in Chinese Soybean Landraces via a Combination of Conventional and Bioclimatic GWAS. Three geographic sub-populations among 2000 diverse landraces; 12 SNPs associated with variation in 3 bioclimatic variables at collecting sites.
- Estimates of genetic load in small populations suggest extensive purging of deleterious alleles. Counterintuitively, rapid declines cause worse genetic load for more diverse species.
- Grazing animals drove domestication of grain crops. Small-seeded herbaceous annuals were mainly animal-dispersed, which meant they grew in dense stands on nitrogen hotspots near water sources, making them easily harvested. Hey presto, crops!
- Global impacts of future cropland expansion and intensification on agricultural markets and biodiversity. Expansion mostly threatens biodiversity in Central and South America, intensification in Sub-Saharan Africa, India and China. Prices lower everywhere.
- Domestication and varietal diversification of Old World cultivated cottons (Gossypium sp.) in the Antiquity. G. arboreum first domesticated in Baluchistan 8000 years BP, G. herbaceum much later in Nubia. But they’re really difficult to tell apart in archaeological remains.

WRI report offers menu of silver bullets for sustainable food
The ‘World Resources Report: Creating a Sustainable Food Future’ is out and the news is that “there is no silver bullet.” Rather, there’s a whole list of things that need to be done. For example, we need “[g]enetic tools allowing farmers to select for size, flavor, and temperament of vegetables.”
No wait, that’s The Onion, my mistake. It’s National Geographic I was looking for.
Here’s the actual, very sensible, menu:
- Reduce growth in demand by cutting food loss and waste, eating healthier diets, and more
- Increase food production without expanding agricultural land area via yield gains for both crops and livestock
- Protect and restore natural ecosystems by reducing deforestation, restoring peatlands, and linking yield gains with ecosystem conservation
- Increase fish supply by improving aquaculture systems and better managing wild fisheries
- Reduce greenhouse gas emissions from agricultural production through innovative technologies and farming methods
Needless to say, agricultural biodiversity underpins pretty much all of the above, including attitude-free vegetables. Maybe there is a silver bullet after all?
The nitty gritty of ABS explained
There’s an update on the nitrogen-fixing maize goop story that we blogged about a few months back. It’s from YaleEnvironment360, so you know it’s going to be good.
A Mars subsidiary called BioN2 had signed an agreement with a village to share financial benefits from the maize’s commercialization. That village turned out to be Totontepec, a Mixe indigenous community in the mountains of eastern Oaxaca… The UC Davis/Mars researchers received a certificate of compliance with the Nagoya Protocol, an international agreement aimed at compensating indigenous communities for their biological resources and traditional knowledge.
Sounds good, right? But questions remain.
Still, the situation surrounding Totontepec’s maize raises complex questions about how indigenous communities equitably benefit when research scientists and multinational corporations commercialize local crops and plants. Should Totontepec’s maize turn out to be a miracle, self-fertilizing crop whose genetic traits can be replicated worldwide, will the community’s Mixe people receive a significant long-term share of profits, which could potentially number in the millions of dollars? How does Nagoya ensure that the rights and interests of small indigenous communities are safeguarded when their leaders negotiate complex deals with international lawyers and executives? And, not least, when a valuable plant is found throughout a region, is it fair for a single village such as Totontepec to reap financial benefits from its maize while neighboring communities with identical or similar maize receive nothing?
These questions, and others, are discussed in the article, which is really a model of its kind, courtesy of Martha Pskowski.
An indicator for the conservation of socioeconomically and culturally valuable plants
The CIAT/CropTrust proposal for the calculation of “Comprehensiveness of conservation of socioeconomically as well as culturally valuable species” is up on the Biodiversity Indicators Partnership website.
Here’s a recent blog post on the indicator, which is relevant for Aichi Target 13 and SDG 2, Target 2.5.
And here’s the underlying paper which described the method in detail: Comprehensiveness of conservation of useful wild plants: An operational indicator for biodiversity and sustainable development targets.
Finally, here’s the website where you can explore the data.

- Genebank genomics bridges the gap between the conservation of crop diversity and plant breeding. What do we want? An accurate genotype-to-phenotype map for all seeds stored in the genebank. When do we want it? As soon as we have the money to ensure their conservation.
- The origins of cannabis smoking: Chemical residue evidence from the first millennium BCE in the Pamirs. Well, that’s like your opinion, man. Residues in incense burners used for mortuary rituals, if you must know.
- Patagonian berries as native food and medicine. Good, and good for you.
- Revisiting the Origin of the Octoploid Strawberry. Not 4 separate diploid progenitors, as another paper recently found, but rather 2 extant ones, once you re-do the math.
- The Nutritional Contribution of Potato Varietal Diversity in Andean Food Systems: a Case Study. It’s great, but it’s not enough.
- The origins and adaptation of European potatoes reconstructed from historical genomes. Sequencing of old herbarium specimens, including Darwin’s, shows that early introductions to Europe were from the Andes, and later admixed there with Chilean and wild material, forming a sort of secondary centre of diversity.
- Effect of Intensive Agriculture-Nutrition Education and Extension Program Adoption and Diffusion of Biofortified Crops. Breeding is not enough.
- Morphological characterisation and evaluation of cacao (Theobroma cacao L.) in Trinidad to facilitate utilisation of Trinitario cacao globally. Now we know which ones are the best, for different reasons.
- Evolution of US maize (Zea mays L.) root architectural and anatomical phenes over the past 100 years corresponds to increased tolerance of nitrogen stress. There has been unconscious selection for root traits resulting in better N use efficiency. An old paper, resurrected because of the next one.
- Breeding improves wheat productivity under contrasting agrochemical input levels. Breeding wheat in Europe for good performance under high input levels has not markedly affected its performance under more challenging conditions. Diversity has held up too.
- Positive outcomes between crop diversity and agricultural employment worldwide. Irrespective of input levels and economic growth rates.
- National food production stabilized by crop diversity. Crop diversity is not just good for rural employment (see above), but for year-on-year production stability too.
- Climate change and cultural resilience in late pre-Columbian Amazonia. And it was sort of the same in ancient Amazonia.
- Effects of Fairtrade on the livelihoods of poor rural workers. Fairtrade improves wages of workers in cooperatives, but not on small farms.
