Objectives: Using emergy analysis to assess agroecosystem sustainability helps implement management practices that improve production resilience.
The Damask rose scientifically name as Rosa damascene Mill. from rose family, is cultivated in hot and arid regions of the nation, leading to the economic development of these areas. Thus, this plant must be grown in arid regions. This study examined Damask rose production's mechanized and traditional agroecosystems in Nehbandan, Iran, for sustainability.
Materials and methods: The study was conducted in Nehbandan, situated in the South Khorasan province, to compare the mechanized and traditional methods of Damask rose production. The study analyzed the inputs' structure and emergy-based indicators in both mechanized and traditional rose production methods.
Results: The study computed the emergy input for the traditional and mechanized Damask rose systems as 7.17E+16 and 5.11E+16 sej/ha/yr, respectively. The emergy yield ratio (EYR), environmental load ratios (ELR & ELR*), and environmental sustainability indices (ESI & ESI*) indicate that the traditional ecosystem exhibits greater ecological efficiency and is more proximate to optimal conditions when compared to the mechanized ecosystem.
Conclusion: Practical solutions in comprehensive management, particularly in soil organic matter protection and loss prevention, can significantly impact the ecological sustainability of the mechanized Damask rose production system. To increase economic stability in the traditional production system, users should improve their technical skills.
