Green Infrastructure Approaches in Watershed Planning: The Review

The 2024 UNESCO assessment predicts that half of the world's population would face water scarcity by 2050. Currently, 3.5 billion people lack basic sanitary facilities, and 2.2 billion people lack access to clean drinking water. Over 1.4 billion people have experienced droughts since 2002, and as a result of climate change, the frequency and severity of water shortages are expected to increase. It is predicted that the number of urban dwellers experiencing water shortage will quadruple by 2050, further taxing both natural habitats and cities. In addition to restricting access to energy, these water constraints are contributing to a rise in food insecurity. Meanwhile, the International Energy Agency (IEA) highlights the ongoing global energy emergency, which has caused fuel prices to soar to record levels, pushing millions into poverty. Addressing these challenges requires holistic solutions, such as effective efficient water management techniqueslike rainfall collection and groundwater restoration, coupled with a transition to renewable energy sources. This study explores how these combined approaches can enhance resilience, ensuring reliable access to water and energy for vulnerable populations
