- Determinants of Sustainable Organic Food Consumption in TunisiaPublication . Zaidi, Saida; Fernandes, António; Ribeiro, Maria IsabelOrganic farming plays a crucial role in promoting sustainable agriculture by preserving ecosystems, enhancing biodiversity, and ensuring the production of healthier food. As the demand for organic products continues to rise globally, understanding the factors driving organic food consumption becomes essential for fostering sustainable consumer behavior. Tunisia, with its deep-rooted agricultural heritage and growing interest in organic and sustainable living, presents a unique case for examining these dynamics. Given the country's ongoing economic development and urbanization, it is critical to explore the factors shaping consumer choices regarding organic food. This study aims to analyze the factors influencing organic food consumption in Tunisia by assessing consumer attitudes, purchasing habits, and barriers to adoption. Using a quantitative approach, data were collected through a structured survey targeting a diverse sample of Tunisians that explored socio-demographic characteristics, economic constraints, motivations, and challenges to organic food consumption, with statistical analysis applied to identify key trends and correlations. Findings reveal that 23% of respondents purchase no organic products, with supermarkets dominating distribution channels and limited availability through direct farmer sales or specialty stores. Consumer knowledge is notably deficient, with over 60% of participants demonstrating limited understanding of organic food. Regression analysis identifies attitudes toward organic food as the strongest predictor of purchase intention, followed by health awareness, while perceived price negatively affects consumption. Interestingly, environmental concerns showed no significant association with purchase intention. These results show the need for strategies that improve attitudes and address price concerns to boost organic food adoption in Tunisia.
- The effect of environmental and social concerns on sustainable consumption among Portuguese higher education studentsPublication . Ribeiro, Maria Isabel; Fernandes, António Pedro; Fernandes, Ana Isabel; Fernandes, AntónioSerious environmental and social problems, notably global warming, pollution, biodiversity loss, natural disasters, and the increase in poverty, among others, have encouraged the consumption of environmentally friendly products and amplified actions in favor of the most vulnerable population. This is why sustainable purchasing behavior has received increasing attention from academia, companies, and other professionals in the field. According to the literature, environmental and social concerns significantly increase consumer loyalty to more sustainable products. This article aimed to analyze the relationship between environmental and social concerns and sustainable consumption from the perspective of students attending higher education in Portugal and to determine whether the effect differs by nationality. Participants were selected using a non-random sampling technique. The empirical study was conducted in Portugal between October 2024 and January 2025. The questionnaire, distributed online, contained, in addition to sociodemographic variables, the dimensions of social concerns, environmental concerns, and sustainable onsumption from Hamza et al (2023). For all dimensions, a 5-point scale ranging from 1 (strongly disagree) to 5 (strongly agree) was used. The sample consisted of students attending Portuguese higher education institutions who voluntarily participated in this study. A total of 675 valid responses were considered, of which 493 responses were from students of Portuguese nationality, and 182 were responses from students of other nationalities. The data were edited and processed using Jamovi version 2.7.12.0. First, descriptive statistics were calculated. Subsequently, exploratory factor analysis was employed, and a multiple regression model was subsequently estimated for Portuguese and other nationalities. The results showed that, regardless of nationality, environmental and social concerns were positively associated with sustainable consumption. For students of Portuguese nationality, these variables explained 61.6% of sustainable consumption, whereas for students of other nationalities, the recorded value was 70.2%. Furthermore, social concerns took precedence over environmental concerns, with a greater impact on international students than on domestic students. Sustainable consumption has been a growing concern since the 1990s. Minimizing environmental pollution and waste, while reducing social inequality, are concerns for everyone, including the productive sector, whose focus should be on meeting consumer needs, who can be important drivers of sustainability by opting for more responsible business practices.
- Perceptions of higher education students on bioeconomy: a comparative study between Portugal and BrazilPublication . Ribeiro, Maria Isabel; Tomazini, Cecilia; Perondi, Miguel; Fernandes, António Pedro Ribeiro; Fernandes, Ana Isabel Ribeiro; Fernandes, AntónioCurrently, sustainability is a pressing issue, driven by environmental disasters caused by human activities that threaten the planet's life. Thus, the aim is to harmonize conflicts between economic, environmental, and social spheres by harnessing the ancestral knowledge of traditional communities and developing clean, innovative technologies that can mitigate the impacts of human actions, generate financial returns, and enhance social well-being. In this context, bioeconomy is considered by numerous scientists, politicians, and managers as a means to achieve sustainability or a bioeconomic state, as it conceives of the economy as dependent on nature; that is, the environment and the economy must be in balance in the same equation, which does not reduce economic activity to a mere mechanism nor nature to a source of raw materials. In this way, the bioeconomy encompasses biotechnology and bioresources, with the development of clean technologies using renewable raw materials to create new bio-based products, as well as bioecology, which involves valuing ecosystem services and promoting environmental protection. However, for the bioeconomy to be widely incorporated into concrete actions, it needs broad social acceptance, since it will be people, especially young people of current and future generations, who will implement it. In this sense, the primary objective of this study was to investigate the perceptions and level of knowledge of young higher education students in Brazil and Portugal regarding the term 'Bioeconomy', and verify whether factors such as nationality, place of residence, and scientific field of study of the course attended influence their knowledge about the topic. A crosssectional, quantitative, analytical survey was conducted using an online questionnaire. The data were analyzed using IBM SPSS Statistics version 28, and the Mann-Whitney and Kruskal-Wallis tests were used to compare knowledge levels between the two nationalities, controlling for place of residence and field of study. The survey received 878 responses, with 74.9% of respondents being of Portuguese nationality and 25.1% being Brazilian. It was found that Brazilian students are more familiar with the term Bioeconomy (53.2%) than Portuguese respondents (37.1%). Furthermore, Brazilians also have a higher level of knowledge, with 47.2% of students classified as having a very good or good level, compared to 22.6% for the Portuguese. Regarding sociodemographic data, for the Brazilian group, an association was observed between place of residence and the level of knowledge in Bioeconomy, with a higher level of knowledge among residents of urban areas. For the Portuguese, the difference was observed in the field of study, with a greater inclination towards Biological Sciences, Agricultural Sciences, and Engineering. Thus, public and private initiatives in countries related to sustainable development and the bioeconomy directly influence students' knowledge and support for the bioeconomy since Brazil makes significant investments in higher education, science, and technology linked to the bioeconomy, which can be evidenced by the higher level of knowledge about the bioeconomy among Brazilians.
- Portuguese consumers' preference regarding the presentation of protected designation of origin transmontano goat cheesePublication . Fernandes, António; Fernando, Sousa; Aveiro, Dina; Ribeiro, Maria IsabelData were collected from a sample of 120 individuals aged between 18 and 84 years old through the application of a questionnaire at the National Agricultural Fair, held from June 3 to 11, 2023, at the National Exhibition Center in Santarém, Portugal. Subsequently, the data were analyzed using descriptive statistics, revealing that the majority of the respondents were male (52.5%), had secondary (25.0%) or higher (41.7%) education qualifications, lived in households of 2 (35.8%) or 3 people (24.2%) with a monthly net income between 501 and 1,000 euros (20.8%) or 1,001 and 3,000 (40.3%) in the districts of Santarém (25.8%), Lisboa (15.8%), or Leiria (9.2%). The majority (84.5%) consumed cheese more than once a week. They preferred cheese made with raw milk (68.3%) from goat (55.0%), with a curing time of around 30 days (55.0%) or 90 days (51.7%). They also preferred the whole cheese (61.7%), certified (59.1%) with Protected Designation of Origin (PDO), Protected Geographical Identification (PGI), or Organic Agriculture (OA). As for the cheese size, the respondents preferred wedges of 220 and 400 g. The most important attribute for consumers proved to be the price, followed by the type of milk (cow, sheep, goat, mixed), curing time, cheese size/portion, presentation form (whole, half, wedge), type of milk (pasteurized, raw), certification (PDO, PGI, OA) and whether the cheese had spices/aromatic herbs. The study reveals that the commercial strategy of the producer group (LEICRAS) should prioritize smaller portions without using spices/aromatic herbs, since opting for smaller-sized cheese entails higher operating costs.
