Since blockchain technology has proven to be effective in the development of a wide range of industries, its use in other fields is also being expanded. Agriculture is one such sector, where blockchain technology is being used to improve farm business operations. Today, several agribusiness firms are utilizing technology to improve food supply chain tracking. For example, Farmers Edge, the world’s leading company that revolutionized the field of digital agriculture through its work in providing advanced artificial intelligence solutions, as well as new opportunities that give agriculture a globally advanced future for all stakeholders, has taken a significant step forward. The issue of blockchain network technology and its applications in agriculture will be discussed in this study, as well as the key advantages that this technology can provide, when employed to make the lives of both producers and consumers easier. In addition, a total of 79 research papers were evaluated, with a focus on the state of blockchain technology in agriculture, related issues, and its future importance, as well as relevant contributions to this new technology and the distributions of this study by different countries.

Apiaries must be ecologically and economically sustainable to provide pollination as a unique ecosystem service. Pollination as an ecosystem service is economically, socially, and environmentally irreplaceable. Therefore, it is essential to improve the profitability of beekeeping activities, which are mainly carried out in rural areas. With this in mind, the main objective of this article is to assess pollination as one of the ecosystem services provided by bees, based on the specificities of Hungarian honey production. The authors’ analysis is based on a Hungarian apiary with 300 colonies active in migratory beekeeping. The model farm produces a wide variety of honey thanks to its migratory beekeeping, visiting several bee pastures during the beekeeping season. This paper presents an approach to quantify the ecosystem services provided by honey bees (Apis mellifera) using two economic valuation methods (productivity change and surrogate market goods) belonging to the family of cost-based valuation. The results of the monetary valuation of the ecosystem services provided by bees can provide a starting point for further research to help decision-makers and farmers to calculate a fair “pollination fee” for beekeepers, which will significantly help beekeepers to maintain beekeeping, an important and beneficial activity for all of us.

The aim of the study is to present the effects of modern broiler production technology on performance and economic indicators. Production and economic data of two broiler farms (new and refurbished farm) of a Hungarian enterprise, both with different standards of technology, were presented on a case study basis and the differences between them were examined. There was no difference in, for example, day-old chickens, feed, litter, animal health, and expertise only in the technical background of the farms. Mortality was 23% lower, total sold live body weight (BW) per m² was 10% higher, adjusted feed conversion ratio (FCR) at 2.6 kg BW was 6.5% higher and European Production Efficiency Factor (EPEF) was 11% more favourable on the new farm than on the refurbished farm (p < .05). Moreover, the new farm is characterised by much more balanced production indicators than its counterpart. While the refurbished farm provided an average net income of €5.1 per 100 kg live BW, it was €9.3 on the new farm (p < .05). The unit cost was 6% lower (p < .05) on the new farm compared to the other one. Although the new farm had almost twice the depreciation per unit live BW as the refurbished farm, animal health costs were 34% lower, labour costs were 27% lower and other costs were 38% lower (p < .05). Moreover, feeding cost and that for day-old chickens were also 5–6% more favourable on the new farm (p < .05). The results show the economic benefits of the modern technical background in broiler chicken production by means of a case study.

This study examines the sustainability and economic viability of intensive common carp (Cyprinus carpio) production in recirculating aquaculture systems (RASs) in Hungary. Using a deterministic model, the research identifies production costs, profitability, and the critical factors influencing economic efficiency. It also evaluates the impact of key variables, such as the feed purchase price, the market-sized common carp sales price, the specific gross yield, the electricity price, and electricity consumption, on economic performance by using a sensitivity analysis. Primary data were collected from an experimental trial conducted under controlled conditions in Hungary, dividing the production process into three phases: pre-rearing, post-rearing, and market-sized fish production. The unit production cost of market-sized common carp in 2024 was 5.47 EUR/kg, with energy (47.01%) and feed (24.18%) as the main cost drivers. While the sales price covered variable costs, it failed to offset fixed costs, resulting in a loss of 0.41 EUR/kg. The results reveal that while RAS technology offers high productivity and efficient resource utilization, its economic viability is challenged by high initial investment and operational costs. Nevertheless, the study identifies optimization opportunities in feed management, water usage, and electricity efficiency to enhance sustainability and profitability. These findings emphasize the importance of integrating economic, environmental, and technological considerations to advance intensive aquaculture practices.

In Hungary, beekeeping is a relatively small-scale sector within the livestock sector, but it is essential for maintaining biodiversity and rural employment. In order to provide ecosystem services such as pollination by honey bees, apiaries need to be economically sustainable, and it is therefore of strategic importance that beekeepers can continue their activities. Based on this, this article’s main objective is the economic analysis of Hungarian honey production, which enables the evaluation of the cost–benefit relationships, production volume and the efficiency of the operation. The authors’ analysis is based on a Hungarian apiary with 300 bee colonies, which also engages in migration and produces a significant amount of acacia honey. The model farm produces several types of honey due to migratory beekeeping, and its average yield reaches 60 kg/bee colony/year, which the authors calculated based on the average purchase prices in 2021. Based on the farm model, the analysis showed that 71 bee colonies and 4253 kg of honey production reached the profitability threshold.

Plastic pollution of oceans and seas is increasing every year and coastal countries need to pay particular attention to this problem. Four Asian countries – Japan, China, Singapore, South Korea – were analysed in terms of the amount of waste and plastic waste generated and their recycling rates. For each country, available data were collected and converted into a common unit of measurement – metric tonnes per 1,000 people. The countries' performance to date was analysed and used as a basis for projections for 2030. Based on the trends so far, Japan has seen an 11% reduction in plastics waste and a 6% reduction in waste over the period, while China has seen a 27% increase in waste and an 8% reduction in plastic waste. In South Korea, plastic waste increased by 49% and waste by 21%. In Singapore, waste decreased by 13% and plastic waste increased by 15%. On current trends, none of the countries are projected to reach their 2030 targets. However, by complying with current and newly introduced regulations, they have a chance to move closer to their targets.
