This paper investigates the relationship between sustainability disclosure, measured by environmental, social, and governance (ESG) combined and individual scores on corporate performance of the agricultural companies from Europe. The main reason of this study is that on 15 November 2022 the worldwide population is more than 8 bn and is expected to increase at 9.6 bn in 2050, which will increase the pressure on agricultural industry to produce food and goods to serve the people needs. In this context and due to the new European regulation, companies must adopt strategies regarding the concerns for environment, social, and governance activities, developing an integrated report to show to investors how they are involved in social issues and environmental concerns. This study uses a multiple linear regression, data being collected from Thomson Reuters database for the period 2017-2021. The results indicate that companies with higher ESG scores have higher performance. This study may help investors and other stakeholders to have an overview as to which sector to orient their investment strategies.

This paper aimed to study several sustainable practices which tourist accommodation establishments can apply to contribute to sustainable development. The application of sustainable practices is essential, as tourist accommodation establishments are very resource-intensive. This paper is based on a quantitative research, and the data has been processed through statistical frequencies. The data were collected through a questionnaire, and the target group was made up of tourist accommodation establishments from four counties of Romania, more specifically Calarasi, Giurgiu, Ialomita and Teleorman. The method through which the results are presented is the graphical method. The obtained results confirmed that the tourist accommodation establishments in the four counties are poorly involved in activities aimed at sustainable development.

Cassava production in the Southern region of Nigeria is seen as one of the prominent cultural practices of the natives. The potentials of cassava derivatives and their value chains are enormous in reducing poverty and triggering economic development in the region. Premised on these assertions, the study was designed to analyze the gross margins of cassava farmers and determine factors that affect it in the southern region of Nigeria. In the study, 120 cassava farmers were randomly sampled using structured questionnaire. The descriptive analyses of the data collected revealed that women dominated cassava production in the region. The farmers were moderately educated with an average farming experience of 11.9 years, and average social capital accumulation, age, farm income, gross margin, and farm size of 6.0 years, 44.3 years, N68, 694.17, N29, 793. 57 and 0.59 hectares respectively. The empirical findings revealed that farmers’ age, education, farming experience, social capital, cassava cutting, and farm size were significant positive determinants of cassava farmers’ gross margins while household size, transaction cost and access to farm credit relate negatively. Based on the findings, it is recommended that youth should be encouraged in cassava production as a way to augment the aging cassava population in the region. Also, adult education should be encouraged among cassava farmers in addition to promoting moderate household size among others.

The article presented the results of a study carried out of the tendencies and changes in the regional aspect of the production of grapes and wine in Bulgaria in the years after the accession to the EU. The dynamics in absolute and relative values of the indicators gross output of grapes, area of harvested vineyards with wine grape varieties, average yields, production of wine grapes and wine by statistical regions was examined. The characteristic of the changes that occurred in the regional plan during the period 2007-2020 was based on the values of the coefficient of structural changes. The levels of the indicator were higher during the first period of application of the CAP in the country (2007-2013), which was mainly due to the contraction of production in the northern regions. In the second period (2014-2020), the impact of financial mechanisms slowed down the negative trends, but they have not been overcoming. Grape and wine production is mainly concentrated in the Southeast and South Central regions. During the next program period, it is necessary to expand and target the set of measures and mechanisms applicable within the Common Agricultural Policy to achieve synergy between economic, social and environmental results in a regional plan.

The sector of traditional products from Romania has been regulated since 2004, but it was not until 2013 that stricter licensing rules were introduced, resulting in a small number of certified products (171 in 2013). However, the sector has developed continuously and in 2022 there were 735 certified traditional products at national level. The purpose of this paper was to analyse the distribution of these products at regional level so we can emphasize a Romanian regional model based on their main characteristics. We used the database created by the Romanian Ministry of Agriculture, Forestry and Rural, respectively, the “National Register of Traditional Products”, which can be found in the “Catalogue of Certified Products and Activities”. The research showed the following profile of distribution: the most important traditional products are the ones made from meat and milk; in Brasov county was, it in the first place with almost 24% of total products; the certified products per producer reached an amount of 14 products in Galati county; most of the products are in Center, north-West and North-East regions. The regional model of distribution is characterized by a concentration of producers in mountainous and rural areas.

Today, rapeseed ranks 5th among edible plant oil, with wide uses in industry and nutrition, as well as in medicine. The use of rapeseed is quite widespread: it is used in the manufacture of margarine, of paints and lakes, of soap, in the textile industry, in combination with sulfur, as well as unrefined oil used in the lubrication of the engines and as biofuel with traits like those of the diesel. Promoters of rapeseed cultivation claim that rapeseed oil is of high quality, for both cooking and salads, being the healthiest food oil. Research on rapeseed and its industrial uses are focused on four main directions: obtaining fuels (known under different names: green diesel, biodiesel, etc.) intended for use in diesel engines; obtaining industrial solvents – because the current solvents of mineral origin contain aggressive and toxic aromatic compounds for humans and animals; obtaining lubricants for industry and agriculture, including hydraulic oils; and obtaining specific fatty acids – especially erucic acid, component of antifoaming products from the detergents industry. Research conducted led to both theoretically and practically important results regarding this crop.

At the same time, a negative impact on consumers is the very high inflation in the Republic of Moldova, which negatively affects the social environment and is caused by the increase in food and energy prices. Similarly, agriculture being an important economic sector for our country, this year has shown a lower productivity than the rest of the economy. Also, national economic agents, facing logistics problems, have generated increases in transport costs for exports from the Republic of Moldova. The aim of the research is to analyze the changes in the agricultural sector in the year 2022 compared to previous years and their impact on the country's population and food security, highlighting vital needs and how to respond to new challenges in the social and economic sphere. The research was carried out based on data provided by the National Bureau of Statistics, the National Bank of Moldova, the World Bank, the National Energy Regulatory Agency and the Food and Agriculture Organization of the United Nations using analytical, synthetic, tabular and graphical methods. On the basis of the research carried out, it was found that the impact of the crisis caused by the multiple changes in the agricultural sector poses a threat to the national economy and to the standard of living of citizens, but these obstacles force the development of the agro-industrial sector and its increased adaptation to the situation created and provides first of all for the development of the infrastructure for production, post-harvesting and processing, which is at an early stage of development and has been influenced by the presence of cheaper raw materials from import.

Traditional products preserve and promote local identity, culture and tradition. They also contribute to the local economy, environmental protection and public health. This paper studied the development of the traditional products sector in Romania in the period 2013-2022. The main objective was to show the distribution among product types and landforms. The information was gathered from two main sources, the “National Register of Traditional Products” and the “Catalogue of Certified Products and Activities” of the Romanian Ministry of Agriculture, Forestry and Rural Development. The research showed that almost 41.6% of traditional products are found in the meat and meat products category, followed by milk and dairy products with 18.2%. They are mainly produced in mountain and lowland areas. In the period 2013-2022, an increase in product structure can be observed in beverages and bakery products in lowland areas, vegetable and fruit products in mountain areas, and fish products in mountain areas.
