[Criteria] Agriculture [Egyptian Science] By 3000 BC agriculture had been developed making heavy use of the regular wet and dry periods of the year. The Nile flooded during the rainy season providing fertile land for growing crops. High yields and productivity were obtained from the nature of the fertile Nile valley land, not from any particular advanced agrarian techniques Agricultural techiques remained virtually unchanged for thousands of years since the early dynastic Period, into the Ptolemaic Period The vast majority of the population was employed in agriculture, in order to mantain enough supply for the elite classes [Renaissance Science] 
Agricultural advances and irrigation systems, resulted in improved farming methods and increased crop yields. Thanks to improved irrigation systems and new hydraulic machinery, land that was either too wet or too dry could now be farmed. This helped expand the amount of land for farmers, in turn producing more food for both animals and humans This advanced agricultural systems allowed for a high percentage of the population to work in other professions, while fewer farmers easily maintained the required food surplus for the entire population, this is in contrast with the agrarian Egyptian society, in which the vast majority of the population had to work as farmers to produce sufficient food supply for mantaining the ruling class and priesthood
