Chapter Overview
Chapter 2, 'Water Sources and Management', covers the global and national distribution of water resources. It introduces the primary water sources of the world (including oceans, lakes, rivers, glaciers, and aquifers) and contrasts them with Pakistan's specific water assets (such as dams, rains, and glaciers).
The chapter highlights critical challenges like low groundwater levels in Pakistan—driven by water-intensive irrigation, reduced rainfall, deforestation, and rapid urbanization—alongside the scarcity of drinking water in cities. It also explains the physical mechanisms of the water cycle and types of precipitation.
Lastly, students learn about modern water management and purification. This includes sewage waste utilization and treatment methods, biogas as an energy resource, and primary purification technologies like distillation, reverse osmosis (RO), activated carbon, and UV disinfection.
