Decrease the price of grain/legumes

The US is the biggest exporter of corn and soybeans in the world. Transportation costs are important, but are unlikely to be changed by your consumption habits. The price of corn delivered FOB New Orleans, is going to be its price at Omaha, plus rail/water to the port. The price delivered at say, Mombassa, Kenya is going to be the FOB New Orleans price, plus the shipping and handling costs. Unless some other grain source makes US corn uncompetitive there. The price of US corn delivered Kigali, Rwanda, is going to be the price at Mombasa, plus any cost to due trade barriers in Rwanda, plus the cost of transport (by truck?) Mombassa-Kigali (assuming, as is likely, a more or less free market in grain and trucking in Kenya and Rwanda) I doubt there are any significant trade barriers limiting the import of grain to Rwanda.
So yes, ceteris paribis, an increase in the price of corn in Omaha, results in an increase in the price of corn in Kigali. (Is ceteris parabis valid? Well a really big fall in the price of corn in Omaha MIGHT lead to shortages of transport capacity along the pipeline, and offsetting increases in costs - but for the most part barriers to entry in the relevant transport industries (US rail aside) are not that high, and the market should adjust and provide the demanded capacity.
Grain, in fact, IS probably one of the more fungible commodities in the world. Corn is rather more fungible than wheat, which has different varieties differing in gluten and protein content, creating effectively different markets. Soy, I dont recall, I think its less fungible than corn but more so that wheat.
And yes, Ive dealt with some of these issues in a professional capacity.
Now of course your PERSONAL consumption isnt going to matter much, cause youre only one dude. A drop in the sea. Same way your gifts to charity (unless youre very wealthy) wont matter much, either.
But if large numbers of people change consumption patterns, that would matter.
At the moment, IIUC, the increased consumption of animal protein in China, as it becomes richer, IS expected to impact world grain prices (including in Africa)
