Climate change (CC) and climate variability (CV) are causing irregular precipitation, rising sea levels, and frequent extreme weather events, which threaten global agricultural crop production through prolonged droughts, floods, and shifting agroclimatic zones. Addressing greenhouse gas emissions and ensuring food security are among the greatest challenges of this century. Climate Smart Agriculture (CSA) emerges as a global strategy to enhance food productivity amid these uncertainties. CSA aims to create climate-resilient agricultural systems that increase soil health, water, and nutrient efficiency, provide stable yields, and reduce greenhouse gas emissions. By improving farmers' incomes and resilience to climate impacts, CSA contributes to both climate change mitigation and adaptation. Future CSA development directions include leveraging advanced internet technology for secure agricultural information, optimizing cropping patterns and management, integrating "internet + weather" services, and implementing agricultural weather index-based insurance. These strategies offer new pathways for ecological protection, green agricultural development, and climate change mitigation.
