Document Summary
1st jump: 600,000 yrs ago the use of fire. 2nd jump: 40,000 yrs ago appearance of language radical change in lifestyle: growing consumption > growing population. The seventh jump: historical aspects about water (natural resources) Africans, mesopotamians, romans, mayas, incas, egyptians learned the fundamental rule of gravity: water flows downhill. Gravity controls river floods, run off, groundwater recharge, and filling of lakes: understanding of watershed functioning and interconnections. Gravity was the water management principle from the beginning of agriculture (ca. Nevertheless, even today, gravity plays a central role in water management (e. g. colorado river los angeles and phoenix) Evidence of a possible artificial lake: understanding of watershed functioning and gravity principles. Ii. quantity and quality: scale structure (societal organization) a matter of scale. Based on archaeological evidence, we know that the most ancient and effective irrigation works for agriculture involved small villages, before great empires were formed.
