The book examines boatbuilding techniques, trade networks, and the exchange of goods, illustrating how rivers served as arteries of commerce. It also details farming practices like irrigation and flood management, which supported the growth of settled communities. By integrating insights from archaeology, anthropology, and environmental history, the book provides a holistic understanding of early settlements.
The book unfolds by first introducing foundational concepts and then developing its argument through three major sections: trade and transportation, farming techniques, and daily life. It offers a fresh perspective by examining riverine communities through the lens of ecological interdependence and indigenous knowledge, challenging conventional narratives and highlighting the resourcefulness of these early societies.
