Environmental and economic influences of postharvest losses across the fish-food products supply chain in the developing regions

Postharvest and supply chain losses are the main global challenges. The security of future food demand requires certain availability of natural resources and useful application of limited means. This study is based on maximizing the productive use of baren fish farms to meet future food demand. In this work, the simulation optimisation model was used to determine the estimated findings. We developed the life cycle measurement technique to examine the percentage loss occurred during postharvest and supply chain process and the assessment of its economic, environmental and social influences. Results demonstrate the variate average change of postharvest loss and supply chain loss of a farmer, processors, trader, wholesalers and retailers are, respectively, 7.06%, 8.89%, 6.23%, 9.10% and 13.05% regarding sample fish-form as compared to same capacity healthy land fish-form with a productive supply chain operation. The total healthy mud of land and quality water consumed to produce this lost food accumulated 60 thousand hectares and 255 million cubic meters apart from other producing inputs. It is estimated cost $380 million annually 7.8 million tons of growth. The study reveals the significance of better prevention approaches of life cycle waste to reduce the environmental, economic and social impacts. Additionally, it helps to diminish the postharvest loss percentage to decrease the perishability of products throughout the supply chain of aquaculture field and the mechanisms that protect the products until these are sold out to consumers. In order to reduce postharvest losses, the study suggests that farmers be included as supplier actors and measured twice, first at the production stage and then at the supply chain stage. With the use of well-organized techniques, the farmer's education is a key component in reducing postharvest losses of perishable goods and boosting aquaculture sectors. Therefore, sustainable economic growth requires from farmers to supplier and productive coordination in reducing environmental impacts. This could improve their learning, skills and practices towards sustainable growth achievement in perishable products for meaningful use of natural resources.
