abstract
This study was conducted to assess the impact of sustainable development policies for orange trees on the efficiency of land use in three aspects: economic, social, and environmental, thereby proposing some solutions for sustainable orange development in Bac Quang district, Ha Giang province. The research results show that sustainable development policies for orange trees have a positive impact on economic, social, and environmental efficiency indicators with indexes ranging from 3.59 to 4.3 (impact levels 1 and 2). However, orange cultivation in Bac Quang district still faces some difficulties in consumption and capital shortage. In addition, many of the King orange gardens also have yellow leaves, dry branch tips, degeneration; unplanned expansion of orange acreage; and fake and poor-quality fertilizers. To sustainably develop orange trees, it is necessary to implement the following solutions: apply appropriate cultivation measures to overcome yellow leaves, dry branch tips, and degradation; review and orient the development of orange acreage according to the planning; manage fertilizers and pesticides; promote production and consumption of oranges according to the linkage chain and value chain applying 4.0 technology; support organizations, households and individuals to borrow capital; replicate the model of orange gardens associated with digital transformation.
