The earliest Asian civilizations indeed flourished around river valleys, where fertile soil and abundant water supplied by rivers like the Indus and the Yellow facilitated agricultural growth. The most notable of these was the Harappan Civilization along the Indus River, emerging around 2500 BC, which showcased advanced urban planning, intricate drainage systems, and trade networks. In real-world application, understanding the significance of river valleys can help us appreciate how geography influences the development of civilizations. For example, modern cities still thrive along rivers due to water supply, transportation, and fertile land. Recognizing the historical reliance on rivers can also inform today’s urban planning and environmental conservation efforts, as we seek sustainable ways to manage waterways while fostering community growth.
