Chapter 4 Adaptation Measures to Address Global Climate Change

such as coughing and breathing difficulties, while also damaging lung function.
In addition, climate change will increase the concentration and spread of allergens such
as pollen. Rising temperatures alter plant growth cycles, causing earlier initiation and release
of pollen along with increased pollen production. Concurrently, changes in wind patterns
and precipitation also affect pollen dispersal paths and ranges. For individuals with allergic
diseases (such as allergic rhinitis and asthma), heightened pollen concentrations and expand-
ed distribution areas lead to exacerbated symptoms and increased attack frequency. Patients
with allergic rhinitis experience nasal itching, sneezing, rhinorrhea, and nasal congestion,
significantly impairing quality of life. Asthma patients may suffer allergen-induced attacks
from pollen exposure, manifesting as wheezing, shortness of breath, chest tightness, and
coughing, with severe cases even becoming life-threatening.
Deteriorating air quality has led to a rise in the incidence of respiratory and cardio-
vascular diseases, significantly increasing healthcare demands. Public health systems face
tremendous pressure in disease prevention, diagnosis, and treatment. For disease prevention,
it is necessary to strengthen air quality monitoring, promptly issue air quality warnings, and
remind the public to take protective measures. Concurrently, health education campaigns
should be conducted to enhance public awareness of air pollution hazards, advocating envi-
ronmental protection behaviors such as green commuting and energy conservation to reduce
pollutant emissions. In terms of diagnosis, medical institutions need to be equipped with
advanced detection equipment to improve diagnostic accuracy for respiratory and cardio-
vascular diseases. Regarding treatment, increased medical resources including medications,
medical devices, and healthcare personnel must be allocated to meet patient needs. However,
due to the complexity and long-term nature of air pollution issues, coupled with the relative
scarcity of medical resources, public health systems face numerous difficulties and challeng-
es in addressing health problems caused by deteriorating air quality.
(4) The Indirect Impacts and Pressures of Food Security Issues on Public Health
Extreme climate events, such as droughts, floods, and heatwaves, have severely affected
crop growth and yields.Drought canLead to insufficient soil moisture, stunted crop growth,
and even withering and death of plants, resulting in reduced crop yields. In drought-prone re-
gions, crops fail to grow properly due to water scarcity, leading to significantly reduced grain
production and severely affecting local residents’ food supply. Flood disasters submerge
farmland, destroy crops, and cause complete crop failure. Floodwaters also wash away ag-
ricultural infrastructure such as irrigation systems and farm roads, hampering subsequent
agricultural production. High temperatures disrupt crop photosynthesis and respiration, lead-
ing to poor growth and development with lower yields. Additionally, climate change triggers
outbreaks of pests and diseases, further threatening crop growth and yield. The proliferation
of pests and diseases infests crops, degrading their quality and reducing production.
Food security issues lead to reduced grain supply and intensified price fluctuations. In
regions with food shortages, malnutrition is more prevalent. Children, pregnant women, and
