Agriculture and rural development has continuously been a hot debate and received significant attention from literature. In this context, endogenous development is considered to be basic approach for rural development strategies in many countries of which the Japanese model namely One Village One Product (OVOP) is a successful one. This paper studies the OVOP movement and analyzes its early adaption in Vietnam, the so-called One Commune One Product (OCOP). This question is addressed by reviewing the existing literature on OVOP following by a case study in Quang Ninh province, Vietnam. The results, reveal, in practice, despite some criticism, OCOP strategy in general generate employment opportunities, incomes; enhance creativity and capability of local people.

Dak Lak province, Central Highlands, Vietnam presents an interesting case in perennial crop systems, of which coffee and black pepper are the two premier commodities and contribute a large part to economic growth provincially and at the national level. In recent years, in addition to mono-cropping systems, intercropping systems for diversification have developed quickly. This paper focuses on (1) comparing the economic efficiency of mono-coffee systems (MCSes), mono-pepper systems (MPSes), and coffee and pepper intercropping (CPI) by analyzing startup cost, annual cost, and profits; and (2) identifying the main factors affecting farmers’ decisions to convert their crop systems. The study was carried out by investigating 90 perennial crop samples using the three perennial crop systems (MCSes, MPSes, and CPI) in 2017–2018. Additionally, in-depth interviews and focus group discussion (FGD) methods were applied to collect more information about the operations of each system. Another survey with 37 samples (new plantations) was carried out to compute the startup cost. The findings showed evidence that MCSes had the lowest startup and annual costs, whereas MPSes had the highest costs of the three perennial crop systems. MCSes used less manure or compost in the initial setup and overused chemical fertilizer in annual production. Similarly, MPSes had high pesticide-stimulant costs in the production process to sustain crop development. The study indicated that CPI not only had the highest economic efficiency, but also created the best family employment opportunities of the three systems. Additionally, the study found some social factors that strongly influenced farmers’ decisions to shift their cropping system: These included ethnicity, education, training, and crop failure, in addition to economic factors (profits).

The study was conducted in Xuan Thuy National Park to provide a comparative assessment of different farming systems under the context of the coastal zone development of Vietnam. Based on a sample of 234 farmers in this area, SCP (Structure–Conduct–Performance) analysis revealed three farming systems: integrated aquaculture–mangrove (IAM), intensive shrimp (ISH), and rice-based (RB) farming. The evaluation of farm performance among the systems indicated that ISH incurred the highest values of variable cost and sustainable family income. Meanwhile, IAM obtained the lowest production cost due to the availability of allocated natural resources. The imbalance of applying synthesized fertilizers and an overdependence on nitro-based fertilizers were reported in the case of RB systems. In comparison with the other coastal areas of Vietnam, these farming systems achieved a lower level of production efficiency. It is urgent for policy makers to take action to promote sustainable farming practices in accordance with the stringent enforcement of environmental standards to reduce potential impacts and strengthen the coexistence of systems. Additionally, the purpose of securing rural livelihood under coastal development is aligned with the recommended solutions for economic improvement in this study.

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.

Crop conversion from inefficient rice fields to lotus cultivation has been strongly promoted in low-lying areas of Thua Thien Hue Province in recent years. To assess the opportunities and constraints of lotus farming, this research applied a mixed-methods approach, including key informant interviews, focus group discussions, and a household survey with 95 lotus farmers. Two main factors that drove the shift to lotus cultivation were the limitations of the rice farming system in low-lying areas and farmers’ expectations of high economic returns from lotus crops. In addition, crop conversion policies have played an important role in facilitating land access for farming households. Despite being perceived as a high-value crop, lotus production has proven economically unviable for most surveyed households in 2024. Smallholders who rely on family labor tend to achieve higher efficiency, highlighting a paradox where increased scale does not lead to greater profitability. Consecutive crop failures caused by nematode diseases and unfavorable weather, combined with high production costs, have posed serious challenges, particularly for larger farms. These findings suggest that promoting indigenous lotus varieties, expanding mechanization, encouraging farmer cooperation, and improving post-harvest practices are essential to enhance production efficiency and support the sustainability of the lotus sector.
