A number of studies have indicated that short food supply chains could create economic, social, and environmental benefits, but most of those chains were implemented in developed countries. This research aims to find out the characteristics of short food supply chains and their benefits to small farmers in Vietnam, which is a developing country, based on the survey results from 338 small farmers in the third quarter of 2020, with the support of Stata 14 software. The results showed that the short food supply chains in the survey sample in Vietnam were characterized by two main actors: small farmers and distributors. Farmers could sell products flexibly at the local market. There was some initial evidence to prove that these chains helped to stabilize the input, output price, and revenue; formulated sustainable income; and increased the satisfaction and confidence of farmers. They eliminated gender discrimination in rural areas and improved livelihood for ethnic minorities. These chains also enhanced the mindset on green, organic, and clean production of farmers, which in turn created environmental benefits. COVID-19 has posed a negative impact on the income of farmers and made them change their production and sales method. Therefore, the research could suggest some policies to sustainably develop the short food supply chains in Vietnam in the future.

Goats are produced in Laos on a small scale and most of them are exported to Vietnam, where they receive a price approximately 30% higher than Vietnamese crossbred goats. In 2021, Laos exported 2.2 million dollars in sheep and goats, mostly to Vietnam (2.19 million dollars). Vietnam was also the fastest-growing export market for sheep and goats of Laos between 2020 and 2021, comprising 66.7% of the total exports. This study aims to analyze the goat value chain from Laos to Vietnam and, based on its characteristics, to suggest policy interventions for the socio-economic sustainable development of the chain. This research analyzes a sample of 400 survey interviews of goat chain actors collected during the second and third quarters of 2022, with the support of CommCare software version 2.53.1. The results show that the Lao goat chain has four main functions implemented by four prominent actors: goat-rearing farmers, traders, abattoir owners, and restaurant owners. However, the role of input suppliers is unclear in this chain. Support to the stakeholders has been provided by local authorities and the government, projects and NGOs, technical supporters, and license supporters. There was not any clear evidence of the goat processing industry. Vertical and horizontal linkages between stakeholders exist, but agreements are primarily oral. There is no declaration of leading actors, and a traceability system has yet to be implemented. The increase in Lao goat exports to the Vietnamese market is driven by the high demand from Vietnamese consumers. The commercialization of goats’ yields provides a positive net income in Lao, where all actors benefit, especially traders and restaurant owners. The chain also creates job opportunities and income that improve living standards, especially for disadvantaged groups, such as women, middle-aged people, people with low literacy, and those living in rural areas. For the sustainable development of the chain, this research recommends that the Lao and Vietnamese governments work together to develop more favorable conditions for goat trading, to improve the traceability across the goat chain, to promote goat husbandry and feeding practices, and to foster goat farmer collaboration by sharing goat-rearing experiences.

Goats are the fastest increasing livestock population on earth, growing by 29% in the past decade. In Vietnam, goat numbers grew remarkably faster at 103% in the same period. To understand the reasons for this rapid growth and implications, we explored the characteristics of Vietnamese goat supply and demand and identified risks and opportunities for smallholder goat producers. Our analysis finds that the continued growth of goat consumption in Vietnam is driven by Vietnam’s: (1) large and growing population (97.3 million) and economy; (2) high meat consumption relative to Gross Domestic Product; (3) high social value placed on goat consumption; (4) increasing popularity of meat consumption; (5) established socio-cultural goat consumption practices; (6) increasing preference for grass-fed meat; and (7) increasing supply from neighbouring countries. As a result, growth in Vietnamese goat meat prices has continually outperformed growth in goat supply over the past decade. Supply is mainly produced by thousands of smallholder farmers in Vietnam and neighbouring Laos. Hence, there are important livelihood and rural development opportunities for producers to increase and diversify into goats. In Laos, each additional goat sold represents a 4.75% increase in smallholder household income per year. To reduce risks to goat producers, research is needed to: (1) forecast the current and future demand for goats in Vietnam to prevent oversupply leading to price collapse; (2) understand how premiums are awarded for goat characteristics; (3) investigate pathways for formalising trade and its impacts on smallholders; and (4) establish strategies for producers to improve supply without degrading natural resources, or increase disease outbreak risk.

Nowadays, Vietnam is known as a developing country with a fast-growing economy. Agriculture is the main traditional sector which plays an important role in Vietnamese economic growth and development. Improving the efficiency of agricultural production towards sustainable development is one of the country’s national economic development goals. This study aims to measure the efficiency of the orange farms which have created jobs and improved living standards for people in Tuyen Quang province, Vietnam. A comprehensive literature review, key informant interviews, and a structured questionnaire were applied in this research for data collection. The data envelopment analysis (DEA) model was applied to evaluate the technical, allocative, cost, and scale efficiencies. The main results of this analysis show that the orange farms have high scores for technical and scale efficiencies. On the other hand, the research reveals low levels of cost and allocative efficiencies. This is in line with the fact that though the farms’ owners have extensive experience in orange cultivation and receive periodic technical training, they still have low levels of education and a lack of economic management expertise. The study results also propose optimal input allocation for the orange farmers. The research could provide crucial information to farms’ owners, the local government, and agricultural planners for formulating effective strategies to improve agricultural sustainability.

Contract farming has become a sustainable strategy in agriculture around the world. Formal farming contract in pig production is one of the priorities of the Vietnamese Government for livestock development. Due to the differences in husbandry methods, a comparison of the technical efficiency between contract and noncontract pig farms has not been studied in Vietnam yet. This study attempts to do so and proposes implications for the sustainable development of pig production in Vietnam. In this study, we surveyed 201 pig farms (63 contract farms and 138 noncontract farms) in Hanoi, Vietnam, and applied data envelopment analysis (DEA) with a meta-frontier. Under group frontiers, the technical efficiency of the contract and noncontract farms are 96.11% and 88.64%, respectively. However, the meta-technology ratios of the two groups are 82.30% and 99.99%, respectively, which means that contract farms’ technical efficiency is lower than noncontract farms. An interesting finding is that although the technical efficiency of contract farms is lower than noncontract farms, their annual pig income is significantly higher, making contract farming attractive to farmers. Results of Tobit regression models showed that land rent is one of the important factors that reduce the technical efficiency of both contract and noncontract farms. This result implies that the Vietnamese government should revise the land limit policy so that farms can own more land. Another finding is that the high feed price reduces the technical efficiency of noncontract farms. The policy implication from this finding is that the Vietnamese government should develop domestic raw material areas for feed production to lessen the dependence on imported raw materials from abroad, which contributes to reducing the feed prices in Vietnam.

This study used an institutional perspective to analyze corporate social responsibility (CSR) practices in Vietnam, which is a developing country with institutional voids and competing normative systems. Data were collected using a survey of 463 managers of 463 Vietnamese companies. Then, a PLS-SEM model was used to assess the roles of individual-level (IND) variables and the organizational context (ORG) in CSR, as well as the influence of the external social context (EXT). The results showed that ORG is the internal factor most strongly associated with CSR (β = 0.258; p < 0.001). IND exhibits a weak negative association with CSR (β = −0.074; p = 0.033), contrary to theoretical expectations. EXT positively moderates the IND–CSR relationship, with governance and tradition being more significant than modernity. The implications suggest that CSR in transition economies may be hybrid and that there is an institutional hierarchy.
