There are various food and ag focused  US-based food and agriculture policy organizations. One prominent one - Food Tank - has on its website - https://foodtank.com/ - various articles on or relating to millets. Most of these are a few years old, but still of interest.

For example:

MILLET(S)

* "Millets and Sorghum: Forgotten Foods for the Future," by Madelyn Vital (April 2018) https://foodtank.com/news/2018/04/icrisat-millets-sorghum-forgotten-foods-future/

Nice overview article including quotes from friend of NAMA, Joanna Kane-Potaka, who was then with ICRISAT as Director of Strategic Marketing and Communication.

SORGHUM

* "Op-Ed | Flour Power: The Strength and Sustainability of Sorghum," by Angela Garbacz (Nov. 2023) https://foodtank.com/news/2023/11/op-ed-flour-power-the-strength-and-sustainability-of-sorghum/

FONIO

* "The Small Seed Changing West Africa," Food Tank (April 2018) https://foodtank.com/news/2018/04/philip-teverow-fonion-seed-africa/

This is an interview by Katherine Walla of Philip Teverow, co-founder of Yolélé (with Pierre Thiam). Philip Teverow gives some background on fonio, the founding of Yolélé, and the considerations that went into developing the business. Also some discussion of future considerations (still valid today).

I'd read this article in tandem with James Courtright's feature article, "The Fonio Revival" (Roads & Kingdoms / Slate Magazine, 26 Nov. 2017), which sheds light on what was happening with fonio in West Africa that prepared the way for Yolélé and other exporters of fonio. https://roadsandkingdoms.com/2017/the-fonio-revival/

TEFF

* "Opinion | Can a 200 Year Old Farm Pivot from Cash Crops to Ancient Grains?" by Claire Smith (April 2019) https://foodtank.com/news/2019/04/opinion-can-a-200-year-old-farm-pivot-from-cash-crops-to-ancient-grains/

As has been mentioned on this list previously, Claire is the founder of Teffola, and her family farm in Michigan produces teff, largely for Teffola products. This article is her story about that business. (This is the only item tagged teff on the Food Tank site)

Claire's article is apparently the only one tagged "teff," but a Google advanced search turned up another, general, article about teff on the Food Tank site:

* "Indigenous Crop: Teff- Ancient Crop with Modern Potential," by Brett Aronson (Feb. 2014) https://foodtank.com/news/2014/02/indigenous-crop-ancient-crop-with-modern-potential/
