Water is the most important asset of humanity. The ownership and management of this wealth has shaped civilizations over thousands of years. From the first settled farmers to the great engineering works of modern times that alter river courses and store this valuable resource, water has followed human history. It was behind the rise and fall of empires, behind political conflicts that continue to this day, and became the cause of major environmental crises. It is impossible to understand the modern world without knowing our relationship with water. The publishing layout of the book is saved in PDF A4 format.
