Agricultural economics stands at a critical crossroads shaped by climate change, technological innovation, shifting consumer preferences, and evolving global trade dynamics. This review paper examines the multifaceted challenges confronting global agricultural systems, including declining crop yields due to climate variability, market volatility, resource depletion, and persistent food insecurity in developing regions. Simultaneously, it explores emerging opportunities arising from precision agriculture, digital farming technologies, sustainable intensification, and value chain integration. The paper critically analyses policy perspectives encompassing subsidy reform, trade liberalization, climate-smart agriculture frameworks, and institutional support mechanisms for smallholder farmers. Drawing upon recent empirical evidence and global datasets, this review synthesizes current knowledge to propose an integrated framework for sustainable agricultural economic transformation that balances productivity growth with environmental stewardship and social equity.
