Here, from @ecowas_cedeao website, is the actual context: It’s something called a “stock rotation exercise”, a normal, cyclical thing: ecowas.int/ecowas-provide…
“1st Feb 2019. @ecowas_cedeao has carried out a stock rotation exercise of 5,000 Metric Tons (MT) of food grains from its Regional Food Security Reserve by availing it to the Federal Republic of Nigeria on 31st January 2019 in Kano, Nigeria.”
So ECOWAS has something called a Regional Food Security Reserve (RFSR), with physical stock (cereals etc) spread across a number of countries: Ghana, B/Faso, Niger, Nigeria.
