Free the grasspea

Is there a valid scientific reason for the grasspea (Lathyrus sativus) ban in India? We’ve blogged about this before. Mongabay is now on the case.

The claim that khesari dal can cause lathyrism is increasingly being challenged by researchers who feel that the ban was not based on systemic research over a prolonged period.

So what’s the problem?

Sources in the FSSAI ¹ say that the ban has helped people associated with the import of other pulses such as toor dal ². “In the wake of drop in production of popular pulses ensuing imports, traders lobby is benefitted. (Shortage of pulses in India, increases prices, benefitting traders.) They would never want the ban lifted,” said one official on condition of anonymity.

Meanwhile, research and breeding continue.

Indigenous Grasses for Rehabilitating Degraded African Drylands. Promising results, but it’s not easy.
Variability in the Global Proso Millet (Panicum miliaceum L.) Germplasm Collection Conserved at the ICRISAT Genebank. Asian, European and mixed clusters, based on morphology. Out of over 800 accessions, 3 (IPm 2069, IPm 2076 and IPm 2537) are rich in grain Fe, Zn, Ca, and protein.
Household-specific targeting of agricultural advice via mobile phones: Feasibility of a minimum data approach for smallholder context. A little household data goes a long way. Includes crop diversity info?
The genome of cowpea (Vigna unguiculata [L.] Walp.). There’s a gene for multiple organ gigantism.
Reduced response diversity does not negatively impact wheat climate resilience. The suggestion that the statistical methods used were faulty means wheat may not be as in trouble in Europe as a previous paper suggested.
Evaluating WorldClim Version 1 (1961–1990) as the Baseline for Sustainable Use of Forest and Environmental Resources in a Changing Climate. Maybe not as good as it might be. But what’s the alternative?
Worldwide phylogeography and history of wheat genetic diversity. Three groups, with one (the Asian genepool) hardly used in breeding.
Durum Wheat (Triticum durum Desf.): Origin, Cultivation and Potential Expansion in Sub-Saharan Africa. From the Ethiopian highlands and Saharan oases to the mainstream?
Global mapping of cost‐effective microalgal biofuel production areas with minimal environmental impact. The dry coasts of N and E Africa, the Middle East, and western S America. But how minimal is minimal?
From women’s empowerment to food security: Revisiting global discourses through a cross-country analysis. The patriarchy is resourceful.
Genetic association with high‐resolution climate data reveals selection footprints in the genomes of barley landraces across the Iberian Peninsula. Cold temperature, late‐season frost occurrence and water availability have driven landrace genetic differentiation.

The paradox of productivity: agricultural productivity promotes food system inefficiency. It’s the cheap calories, stupid.
Genetic Evaluation of Exotic Chromatins from Two Obsolete Interspecific Introgression Lines of Upland Cotton for Fiber Quality Improvement. Yield from one species, fibre quality from the other.
Resequencing of 429 chickpea accessions from 45 countries provides insights into genome diversity, domestication and agronomic traits. Including drought tolerance.
Genome of ‘Charleston Gray’, the principal American watermelon cultivar, and genetic characterization of 1,365 accessions in the U.S. National Plant Germplasm System watermelon collection. Four genetic groups reflecting geography.
Genome-wide nucleotide patterns and potential mechanisms of genome divergence following domestication in maize and soybean. The best candidates for domestication are plants that are willing to mutate a bit, but not too much.
Crop Biodiversity: An Unfinished Magnum Opus of Nature. “Linking genotype and phenotype remains the holy grail of crop biodiversity studies.”
Meeting global land restoration and protection targets: What would the world look like in 2050? Very nice. It would look very nice.
The ecological drivers of variation in global language diversity. High year-round productivity leads to lots of languages. And lots of biodiversity, but that’s another story.
Product authenticity versus globalisation—The Tulsi case. The division of Indian Holy Basil into 3 types based on traditional knowledge is only partially supported by genetic and phytochemical studies.
A method for generating virus-free cassava plants to combat viral disease epidemics in Africa. Let the distribution commence.
Cereal processing at Early Neolithic Göbekli Tepe, southeastern Turkey. They must have been some feasts.
Persistent Early to Middle Holocene tropical foraging in southwestern Amazonia. On the cusp of agriculture 10,000 years ago in Bolivia. That’s about the same time as Göbekli Tepe, give or take a thousand years.
Moral Hazard: Experimental Evidence from Tenancy Contracts. Tenant farmers should keep a higher share to increase productivity and diversity, but of course the landlords won’t let them so what’s needed is revolution.

Nice synthesis of dog (and chicken) domestication.
Saving the Jala maize landrace in Mexico.
Saving lots of rice landraces in India by eating them.
Myanmar does not live by rice alone. And neither does India.
Saving a whole bunch of stuff in Colombia.
Saving a sorghum wild relative in Australia.
How coconuts can help museums decolonize.
Maybe agricultural development needs to decolonize too. Discuss.
Africa’s Fertile Crescent is the Niger River Basin. Nice, but we saw that coming first.
Citrus is big in Japan.
Olive oil is big in Liguria.
The visnaga cactus was big in the US Southwest once. As an ingredient in candy, of all things.
Breeding filberts in the US.
Tomato 2.0.
And a bunch of other crops American farmers and breeders are having to adapt to climate change.
And not just that, they have to deliver better nutrition too.
Eat what you want, sure. But think what that means for climate change.
Principles for GAIN engaging with the private sector (in all its diversity) on nutrition. Could be applied to engagement on climate change, I suppose, and crop diversity conservation for that matter. My question, though, is: runaway train, or Titanic?

Remember that paper on stunting that we included in Brainfood a couple of weeks ago? It was called What Does Stunting Really Mean? A Critical Review of the Evidence, and the answer to the question in the title was, to put it bluntly: not as much as many think.

Why is that important? Well, because “[s]tunting is commonly believed to cause serious problems, including delayed child development, reduced productivity and earnings in adulthood, higher incidence of chronic diseases including obesity or cardiovascular problems, difficult childbirth, and poor birth outcomes such as low birthweight.” But it turns out that this is not entirely true, and “this subtle misinterpretation could harm the global nutrition agenda.”

That’s from a blog post by one of the authors on the IFPRI website, which also includes a handy video explanation of the subtleties involved. Here’s the bottom line: stunting is not so much the fire as the smoke alarm.
