Agriculture

Not enough food from gathering!
''Our people are starving! Our hunters do not manage to bring enough food for everyone anymore, and we quickly need to find a solution if we want the tribe to keep prospering. Urged by this situation, a young gatherer came forward and proposed something mind shattering to the elders of the tribe: why not make our own plants?''

''He explained how a few weeks ago, one of his piglets dropped a basket full of precious grain harvested in the morning in the muddy soil near his hut; and how they could only recover some of it. he bought them to the same patch of mud; from which now stood a few fresh and green plants bearing the same grain. 'If we cannot find enough plants to feed everyone anymore, then let us make our own!' he said.''

Potential Requirements

 * The triggers for the knowledge agriculture are wildly disputed, one theory is prolonged over-taxation of the production of food gathered from the city tile will trigger Agriculture over time.
 * Potentially triggers based on low food production, storage of crops (Setting minimum stockpile causes low pop usage), having at least 14 farmers working (Could trigger on less, but more farmers in a single city appear to increase it's chance of appearing) (Ongoing test, earliest trigger at 425 culture)
 * Sometimes triggers under the title "Food stagnation" possibly an event that occur's when the game notices a lack of herds in the area near the city. (Ongoing test to verify)
