You missing the point by negating those seasonal schedules in many today existing business plans. Entire industries like tourism or agriculture are entirely rooted in those. Where is constant flow of anything? It exists only in processing scale industries, like chemical plants. However assembly line mass production, like car manufacture, is already an inch under in this scale of industries. Then we have the regular assembly line production. In the end we have workshop scale production. Economy is flexibility. Without flexibility we have no economy. One moment economy is called feudal and next moment it is called mercantile, but it is still the same economy. Sure some economics stay the same, but economy still serves same and one purpose. Economy is a management of finite resources. Even if something catastrophic happens to resources. Economy will simply change. Some economics will die and new will be discovered, but economy survives, so long there is a last human being around.
So what is causing famine? Economy or bad business plan? When government gives up control over economy to "invisible hand of market", then government has to deal with results of human stupidity soon or later. It is so, because economy could arrange even a revolution of starving masses. Economy will eventually fix the human error. Lets be honest, the science of economy is not even looking for the balance of the economic flow. Those people, who think they are in control of economy are using blunt tools like finances. It is like using huge blacksmith hammer to fix watch. Sometimes it works, sometimes it fails. Think about famine happening in a world which overproduces food, which all of humanity needs to survive. This is not even an issue with economy. This is a logistic issue of failed food distribution. Now, what caused that in turn could bring answer where the "human error" idiot is hiding. Maybe it is some mining corporation CEO, who looked to rise profit in his mining corporation (unregulated by local government, who sold them mining permit for a share in profit) up 5%, so he can have 13th wage a year payed as bonus on Christmas. Then economics played in like pollution caused by mining, land erosion due missing farmers gone mining, low existential wages for miners etc etc etc. Then weather got seasonally dry like it always does from time to time. People found themselves in famine. So who caused famine? Economy or unregulated bad business plan?
