Global Climate Change and Its Impacts

and space. In water resource management practices, some regions have achieved scientifi-
callocation and efficient utilization of water resources through constructing large-scale reser-
voirs and comprehensive water pipeline networks, effectively ensuring water supply for local
agricultural production and residential needs. Additionally, installing advanced water-saving
irrigation systems like drip and sprinkler irrigation networks, along with vigorous promotion
of water-saving technologies, can significantly enhance agricultural water-use efficiency,
minimize water resource waste, and maximize the economic and social benefits of limited
water resources.
(2) Promoting Adaptive Agricultural Technologies to Enhance Resilience
Agriculture, as an industry highly sensitive to climate change responses, requires dif-
ferent regions to actively promote adaptable agricultural technologies based on their climatic
characteristics and soil conditions. In areas experiencing gradual temperature increases and
significant precipitation pattern shifts, cultivating and promoting crop varieties with multiple
stress-resistant traits—such as high-temperature resistance, drought tolerance, and water-
logging resilience—has become crucial for stabilizing agricultural production and ensuring
food security. Through long-term agricultural research practices, some regions have suc-
cessfully developed new drought-resistant crop varieties with more developed root systems
that can penetrate deeper soil layers to absorb moisture. These varieties maintain stable yield
levels even under reduced precipitation conditions, providing strong safeguards for local
food security. Simultaneously, timely adjustments to planting systems and agricultural pro-
duction methods are key to enhancing climate change adaptation capabilities. By rationally
advancing or delaying sowing times based on phenological phase shifts caused by climate
change and optimizing crop spatial distribution, agricultural efficiency can be improved. In
climatically suitable regions, transitioning from traditional single-crop annual systems to
double-crop or triple-crop biennial systems allows full utilization of climatic resources, sig-
nificantly enhances land use efficiency, and maximizes agricultural production benefits.
In coastal areas, the development of salt-tolerant agricultural technologies holds sig-
nificant practical importance due to the impacts of seawater intrusion and rising sea levels.
By screening and cultivating salt-tolerant crop varieties alongside rational soil improvement
measures—such as irrigation and drainage for salt leaching, application of soil amendments,
and others—agricultural production can be successfully conducted on saline-alkali lands,
creating new opportunities for agricultural development. Additionally, promoting facili-
ty-based agricultural technologies, such as constructing greenhouses, can effectively regulate
crop growth environments and substantially mitigate the adverse effects of extreme weather
on agricultural production. Through precise control of temperature, humidity, and light con-
ditions within greenhouses, stable and suitable growth environments are created for crops,
thereby ensuring both yield and quality of agricultural products.
