The rapid growth of sedentary agriculture occurred during the Neolithic era; this precipitated advancement in technology and socialization. This rapid growth allowed for the evolution of a wide range of agricultural implements along with the improvement of seed selection, development of water storage, and a rapid rise in the human population marking it as one of the greatest turning points in the history of humankind. Sedentary agricultural occurred in areas already inhabited, but also in new regions. This habitation provided protection for thin and fragile soil, which primarily was found in tropical and semitropical regions. All this was made possibly by the development in the storage of rainwater and rechanneling of river water.
