Chapter Three Impacts of Global Climate Change

placement of residents has plunged communities into chaos, further weakening societal ca-
pacity to address climate change, exacerbating local humanitarian crises, and intensifying the
region’s vulnerability to climate impacts. Through in-depth case studies of typical regions
such as coastal zones and arid/semi-arid areas, we gain clear insights into the unique impacts
of climate change across different regions and their complex vulnerability patterns, offering
valuable experiences and profound implications for global climate change mitigation efforts.

IV. Strategies for Enhancing Regional Climate Change Adaptation
Capacity

Under the macro context of global climate change, different regions exhibit distinct
characteristics in facing climate challenges due to their unique geographical locations, cli-
matic conditions, economic foundations, and social structures. Therefore, enhancing regional
adaptive capacity to climate change requires formulating highly targeted and feasible strate-
gies based on each region’s actual conditions.
(1) Strengthening Infrastructure Construction to Enhance Adaptive Capacity
As the cornerstone of regional responses to climate change, the completeness of infra-
structure directly determines the level of regional adaptive capacity. In coastal areas, given
the continuous sea-level rise caused by global warming and the increasing frequency and in-
tensity of storm surges, the reinforcement of coastal protection infrastructure appears particu-
larly urgent. The construction of engineering facilities such as seawalls and breakwaters with
high disaster-resistant standards can effectively withstand the powerful impact of waves, sig-
nificantly reduce the risk of seawater erosion on land, and provide solid protection for the life
and property safety of coastal residents as well as critical economic facilities. In long-term
practices of coastal protection projects, some countries have successfully withstood multiple
high-intensity storm surges through the construction of complex and robust seawall systems,
effectively maintaining the safety and stability of low-lying coastal areas. Concurrently, the
improvement of drainage systems in coastal areas holds crucial significance for addressing
climate change. With the increasing frequency of extreme precipitation events caused by
climate change, traditional drainage systems are prone to drainage inefficiency when deal-
ing with heavy rainfall, leading to severe waterlogging disasters. Through comprehensive
upgrades to drainage systems—including appropriately enlarging pipe diameters in drainage
networks and enhancing the drainage capacity of pumping stations—rainwater accumulation
can be efficiently and promptly discharged, minimizing the likelihood of urban waterlogging
and ensuring the normal operation of urban functions.
In arid and semi-arid regions, the increasingly prominent water scarcity caused by
climate change has made water conservancy infrastructure construction a core measure to
address water resource challenges. Building water storage facilities such as reservoirs and
cisterns allows full collection and storage of water resources during rainy seasons for dry
season needs, effectively alleviating the imbalance in water resource distribution across time
