For example, engineers have developed methods to improve irrigation systems, such as drip irrigation, which reduces water wastage and increases crop yield.

Another key strategy is through infrastructure development. Engineers design and build dams and reservoirs to store excess precipitation during wet periods so that it can be used during dry periods. This helps in balancing the supply of water throughout the year.

In addition, engineers work towards expanding access to safe drinking water by designing and constructing innovative systems such as desalination plants that convert seawater into drinkable freshwater.

Another important aspect that engineers consider in addressing the impact of population growth on water resources is sustainable management practices. These may include implementing rainwater harvesting systems or wastewater treatment facilities to reduce the burden on freshwater sources.

In conclusion, population growth poses significant challenges on water resources. However, with continuous advancements in technology and innovative solutions developed by engineers, it is possible to ensure sustainable use of these resources for generations to come.
