Smart agriculture in Asia

Faced with a shortage of agricultural land and a changing climate, Asia urgently needs to focus on smart agriculture to meet the food demands of an increasing population. In recent years, advances in information technology and governmental support have promoted the rapid development of smart agriculture in Asia. This study provides a comprehensive review of the progress of smart agriculture in Asia. First, using bibliometrics, we conduct a comprehensive analysis of Asian smart-agriculture research in terms of countries, institutions, and keywords. Second, we investigate innovative technologies used in smart agriculture and provide a systematic summary of agricultural production in Asia, from breeding to harvest. In addition, we conduct qualitative and quantitative assessments of smart-agriculture policies across Asia and present cutting-edge solutions to key challenges such as climate change, labor shortage, and water scarcity. Currently, Asian smart-agriculture policies are insufficient in areas such as risk prevention and control, international cooperation, and standardization. Accordingly, future efforts may focus on enhancing data security and standardization to promote the global development and popularization of smart agriculture. Finally, we discuss trends and challenges that need to be considered and addressed in the future. This review aims to analyze the technical characteristics and application status of smart agriculture in Asia and to provide resources for researchers and policy makers.
