Chapter Three Impacts of Global Climate Change

cades ago and struggles to address emerging challenges posed by current climate change.
Aging reservoirs, irrigation canals, and wastewater treatment plants require substantial fund-
ing for maintenance and upgrades to ensure normal operation and service functionality.
【2】Green Infrastructure Development
Promoting green infrastructure such as rainwater harvesting systems, wetland resto-
ration projects, and ecological slope protection works can effectively improve local climatic
conditions, enhance ecosystem services, and strengthen resilience against natural disasters.
For example, implementing sponge city projects in urban areas—through increased green
spaces and permeable pavement materials—mitigates urban waterlogging risks while im-
proving water resource utilization efficiency.
【3】Introduction of Intelligent Management Systems
Introducing intelligent water resource management systems, including real-time moni-
toring networks, predictive models, and automated dispatch platforms, facilitates optimized
water allocation and enhanced management capabilities. For instance, Israel’s adoption of
advanced drip irrigation technologies and precision agricultural practices has achieved highly
efficient water resource utilization, offering valuable experience for other arid and semi-arid
regions.
Climate change-induced issues such as unstable water supply, deteriorating water
quality, and aging water infrastructure reveal the high sensitivity of modern water resource
management systems to environmental changes. Understanding these problems and their
underlying mechanisms is crucial for formulating scientific and rational water resource poli-
cies. With deepening research and technological advancements, we are confident in gradual-
ly mitigating climate change impacts on water management and building a more sustainable
future. However, given the current severe situation, the international community urgently
needs to strengthen cooperation to jointly explore effective climate adaptation approaches,
ensuring global water security and sustainable utilization.

III. Adaptation Challenges in Urbanization Process

Urban heat island effect, the importance of urban planning with green buildings, and the
resilience enhancement of urban infrastructure constitute critical issuesin addressing urban-
ization under climate change. As global populations concentrate in cities, urban sustainabili-
ty and adaptive capacity become particularly vital.
(1) Urban Heat Island Effect
Urban heat island effect refers to the phenomenon where urban areas experience sig-
nificantly higher temperatures than surrounding rural regions. This temperature difference is
primarily caused by the following factors:
1.Building Materials and Surface Covering
Concrete, asphalt, and otherimperviousmaterials in cities absorb and store heat, gradual-
ly releasing it at night, resulting in markedly higher temperatures in urban centers compared
