Answer 1

Answer:

Since the river valley civilizations were based around rivers, they developed a system of government called Hydraulic Empires. The Hydraulic Empires are a social government structure that maintains power through exclusive control over water access. 

This means that the government developed a bureaucracy and central coordination that controlled the floods and the irrigation that was provided by the rivers.

This is also directly linked to the conversion of more land to productive fields because the food surplus was what made possible the development of these river valley civilizations and when more food was being produced under these Hydraulic Empires, more power for them.
