With the rapid economic development in the past decades, Vietnamese people are more and more aware of the role of safe food for their health and that of their families. Currently, the trend of organic food consumption is happening faster, especially in urban areas. The study aims to determine the influence of transparent information and knowledge about organic products on consumers' attitudes, trust, and subjective norms affecting their purchase intention of organic products. Data were collected from 420 consumers in Da Nang city, Central Vietnam. Exploratory Factor Analysis (EFA) method and Structural Equation Modeling (SEM) were used to evaluate the scale's reliability and identify the impact factors. The results show that attitudes and trust have a positive relationship with the intention to buy organic food. In addition, research shows that trust is a predecessor of attitudes and mediates the relationship between information, knowledge about organic food, and intention to buy organic food. The study's findings are consistent with previous literature and provide implications for food managers, organic food businesses, and the community.

Shrimp–mangrove farming is a favorable production model suitable for the Red River Delta, Vietnam. This study was carried out in Nam Dinh province to evaluate the effectiveness and stability of the shrimp–mangrove farming model in the area. A participatory approach was carried out through surveys, focus group discussions, and interviews with 415 farming households in the Giao Thien and Giao An districts, the buffer zone of Xuan Thuy National Park, in 2022. We then used a cost–benefit analysis model to evaluate the financial performance and stability of the shrimp farming model. SWOT analysis was also used to identify opportunities and threats to this model. The research results showed that the shrimp–mangrove model has the advantages of low investment costs, diversified income sources, low risk, and environmental sustainability. However, the limitations of the model are low financial efficiency and not high stability. The main difficulties of the model are poor quality breeds, diseases, limited farming techniques of farmers, limited infrastructure system, the impacts of climate change, and low productivity. The study also proposes management implications to enhance the effectiveness and sustainability of shrimp farming in the Red River Delta, Vietnam.

This paper empirically analyses the influences of the digital transformation process in the business and public sector on natural resources rents. Our paper employs the digital businesses (e-Commerce, including the value of online selling, e-Commerce turnover, e-Commerce web sales, and e-Business, including customer relationship management (CRM) usage and cloud usage) and the digital public services (user-centricity, business mobility, and key enablers), while we deal with the total natural rents (coal rents, mineral rents, natural gas rents, and forest rents). The various econometric techniques are applied to a sample of 26 European Union countries during the 2011-2019 period. Our estimation results demonstrate that both digital businesses and digital public services lead to a rise in total natural rents. More specifically, the digital businesses appear to have increased influences on coal rents, and gas rents, while the digital public services drive mineral rents, gas rents, and forest rents up. Conversely, digital public services tend to reduce coal rents and digital businesses lead to a decrease in mineral rents and forest rents. Notably, the economic complexity or the quality and diversification of the production system is the key variable for the digital economy aiming at shirking natural rent-seeking. The findings are consistent when we consider the specific type of natural resource rent regardless of whether they are affected differently by digital transformation.
