The Suitability evaluation of circular economics models for sweet potato in Binh Tan district, Vinh Long province, Viet Nam
Abstract
The study was conducted to assess the current production status and natural land potential for the development of circular sweet potato plants in Binh Tan district, Vinh Long province, to propose solutions to increase the economic, social, and environmental value of sweet potatoes. The following methods carry it out: collecting primary and secondary data; synthetic, descriptive statistics; analysis of variance T-test; adaptive assessment; and proposed methods. According to research findings, the sweet potato varieties of purple, white, milk, and red are distributed throughout most study areas. The low economic efficiency due to the complicated situation of the epidemic in the past year caused the price of sweet potatoes to drop significantly. The export of sweet potatoes to foreign countries was limited. Meanwhile, the district has suitable adaptive conditions for sweet potato plants, such as texture, pH, humidity, rainfall, irrigation capacity, etc. The recommended models increase income from growing sweet potatoes and raising livestock, bringing higher economic efficiency to people, more labor needed for people to have jobs, and making full use of agricultural and livestock by-products (unused animal manure, leaves, stems, and roots of sweet potato plants), which limiting environmental pollution when handling improper waste products. The study has proposed solutions to increase the circulation of products, thereby increasing the efficiency of sweet potato production. However, people need to learn the proper use and handling of plant by-products.
