This study assesses the challenges catfish farmers are facing in the procurement of these input resources and coping strategies employed to control them for the farmers to remain in business. This study was carried out in Ibadan, the capital of Oyo State, Nigeria. A multistage sampling method is employed in this study. Three local government areas were purposefully selected among the eleven in Ibadan, Oyo State. The selected local governments were Oluyole, Ido, and Lagelu. Then, the snowball sampling method was employed to administer the prepared structured questionnaire. Descriptive and inferential statistics were used to analyze the data obtained. The results show that the majority (86.4%) of the catfish farmers depend on catfish breeders to source their fish seeds, with many having multiple sources to avoid disappointment in comparing costs and best fish seed. Among the challenges identified by the farmers are bad quality fish seeds that result in stunted growth, high cost of fish seed and fish feed, and poor-quality feed which usually pollutes pond water. Many farmers agreed that they breed their fish themselves to ascertain its quality, and stunted fish should be sold early. Farmers increase the cost price of their fish, use homemade feeds, and buy feeds in bulk to cushion the effect of the high cost of feed.

The paper analyzed the number of beehives and honey production at the global level and in the European Union as well as the main problems honey bees are facing nowadays and how they could be solved. The statistical data for the period 2000-2022 provided by FAOStat, Knoema, Eurostat and other official data bases have been processed using fixed basis and structural indices, trend regression equations (linear and polynomial), R square, descriptive statistics, regression analysis, correlation coefficient, comparison method. Compared to 58.8 million beehives in the world in the year 2000, in 2022 their number reached 102 million (+76.3%). The share of beehives by continent is: Asia 44.6%, Europe 24.7%, Africa 17.7%, Americas 11.4% and Oceania 1.4%. The highest number of bee hives is in India, China Mainland, Turkey, Iran (Islamic Rep.), Ethiopia, Russian Federation, Argentina, Tanzania (U. Rep.), USA and Mexico. In 2022, the EU had 20.27 million beehives, meaning +19.44% versus 2016. The largest number of bee hives in the EU is in Spain, Romania, Greece, Poland, Italy, France, Hungary, Germany, Bulgaria and Czechia. From 1.25 million tons in the year 2000, the global honey production reached 1.83 million tons in 2022 (+45.8%). The regression equation: y = 0.0148 x + 0.4064 shows that an increase by one million beehives will determine a growth by 0.0148 million tons of honey at the global level. From the peak of 22.5 kg honey per bee hives in the year 2005, in 2022, it was registered 17.9 kg at the global level. Honey production by continent in 2022 was: Asia 48.2%, Europe 22.8%, Americas 18.5%, Africa 8.5% and Oceania 2%. In 2022, the top 10 honey producing countries at the global level were: China, EU-27, Turkey, Iran (Islamic Rep.), India, Argentina, Russian Federation, Mexico, Ukraine and Brazil, all together representing 73.6% of the world honey production. In 2014, the EU produced 235 thousand tons honey and in 2022 it achieved 286 thousand tons ( +21.7%). The top honey producing countries are Germany, France, Romania, Spain, Hungary, Italy, Poland, Greece, Bulgaria and Portugal. A bee hives produces 21 kg honey in average, but there are EU countries with higher yields: Finland, Germany, Belgium, Denmark, Estonia, Austria, Italy, Lithuania, Latvia and France. To solve the crisis of biodiversity, pollution and climate change, specific recommendations are destined to improve the ratio between the managed honey bees and wild bees so that the wild bees to have access to flowering sources, to benefit of a suitable habitat to live and reproduce and biodiversity not to suffer. Special measures have to be taken in the cities so that the balance between honey and wild bees to be preserved and the residents and tourists not to be affected. Severe cleaning and hygiene in the apiary, avoiding bees imports, making treatments based on organic medicines could avoid diseases and pests. Farmers have to avoid the use of Neonicotinoids pesticides to help apiculturists not to have bees losses. Beekeeping technology must be adapted to the local conditions and weather alerts, assuring flowering sources, bees reproduction and food storage, as the bee families to pass easier over the winter. An intensified consultancy service, investments in new technologies, a balanced transhumance, more effective marketing actions could increase honey production and quality and stimulate consumption in the EU.

This paper presents the scientists’ interest in studying the topic of unfair trade practices in agro-food chains, trying to answer the questions how important is this topic in academic writing and how it interferes with other terms? Exploring and understanding fairness-enabling practices in the agro-food chain is essential to create a sustainable and resilient agro-food system. The objectives of the research are to identify the main unfair trade practices that impacts the agents along the agro-food chain and the solutions given by scientists to solve inequity. In order to achieve these goals, a systematic literature review of papers covering the topic of unfair trade practices in agricultural sector has been conducted. The results show that there is an increased and relatively recent interest in studying unfair trade practices in the agro-food sector, with a noticeable growth in research since 2018. The main research connections of this topic include sustainability, emerging technologies to improve fairness in supply chains, the role of governance, agro-food policy and producers’ organizations in mitigating unfair trade practices, the impact of different crisis on supply chains and trade practices. The results are relevant for rising awareness of how unfair trade practices impact the agents of agro-food chains and for finding solutions to avoid or reduce them.

The aim of the study is to investigate the spring sap of 15 different grape varieties during the spring season – April 2024 in an experimental vineyard of the Institute of Agriculture – Kyustendil, Bulgaria. The methods used in this research have been: physico-chemical and agro-ecological studies of the spring grape sap and determination of the oxidation sustainability of the sap for each studied grape cultivar, using the Pourbaix pH-Eh water diagram. 1) main conclusion is that the grape sap consists salt on the level of saturation, and this delicate equilibrium in water-salt balance must not be disturbed; 2) the sap is very susceptible to oxidation and adding of ascorbic acid as antioxidant in the soil will be useful for the common physiology of the grapevine cultivars, 3) ascorbic acid circulates in nature and might pass through the root onto the plant, moreover, the roots of the plants may synthesizeс ascorbic acid; 4) grape sap is a bio-indicator for contamination of the environment, and specially of the soil as cyanuric acid and nitrates passes through the root to the plant, but some other contaminators as Pb, As, Radiation cannot be claimed from the present study.

Romania possesses both elements of significance for tourism and a multitude of means that can facilitate activities specific to this field. The distribution of these elements across the territory varies, with some areas having clusters of attractions that have led to concentrations of methods and resources for their development, while other areas are more dispersed. Furthermore, within the first category, local and regional development varies, with certain types of tourism activities becoming prominent, some of which are recognized nationally and internationally, while others, although equally significant, are less known and have fewer means for development.This paper aims to highlight the tourist potential of Dobrogea through tourism products. This endeavor is based on the study and highlighting of the material base necessary for the conduct of tourism activities, as well as the types of tourism products that can be utilized. To this end, we will present a case study focusing on a tourist circuit undertaken by students from Mihail Kogălniceanu Theoretical High School, Snagov, in Dobrogea.

The aim of the research is to group the districts in Bulgaria according to the development of the livestock sector. A hierarchical cluster model was developed based on the indicators for the number of cattle and buffalo, sheep, pigs and poultry by district in Bulgaria. Data on the number of farm animals were taken from the Register of Farmers for the 2020/2021 business year. A dendrogram was constructed showing the distribution of districts by clusters. Average values of the studied indicators for each cluster were calculated. The districts can be divided into 4 clusters according to the considered indicators. The first cluster includes 6 districts: Burgas, Haskovo, Kardzhali, Sliven, Blagoevgrad and Plovdiv. The second cluster includes 17 districts: Kyustendil, Pernik, Sofia-grad, Vidin, Smolyan, Montana, Lovech, Vratsa, Silistra, Gabrovo, Sofia, Yambol, Pazardzhik, Shumen, Razgrad, Targovishte and Pleven. The third cluster includes only one district - Veliko Tarnovo. The fourth cluster includes 4 districts: Stara Zagora, Dobrich, Varna and Ruse.

The paper emphasizes the influence that the Common Agricultural Policy programmes and subsidies on the agricultural production in Romania from the risk management point of view. Agricultural production is deeply dependent on climatic factors. In the perspective of climate changes with increasingly pronounced effects, the European Union, through specific institutions and mechanisms, has introduced financial facilities for agricultural units that apply for insurance premiums for agricultural crops or animals. This approach is likely to increase the share of cultivated areas that are insured, following the model of the west states in the European Union. The present paper centralizes the technical-economic details of some studied agricultural units benefiting from non-refundable financing as a result of applying some insurance policies. Extensive research was made for this article in the North-East Region of Romania, managing to obtain primary sources data from 24 agricultural units and 53 insurance policies applied by these units. The units studied range in size from 148 ha to 1,910 ha. However, most of the units are of the medium-large category, their average exploited area being 521 ha. Moreover, the cumulative area of the studied units is 12,503 ha. It was found that for the 24 agricultural units studied, 80.75% of their cumulative area benefits from insurance against natural disasters. The total amount for the policies paid by the 24 farmers was over 400,000 Euro, while the total value of the settlements by AFIR was 230,141 Euro. The results of the empirical study indicate the increasing interest of large agricultural units in accessing non-reimbursable grants intended for agricultural insurance for cereal crops. The authors have identified the efforts that responsible entities support to maintain this interest, even if the way of organizing reporting and ensuring visibility needs improvement.

While most commercial pineapple farms in Ghana cultivate under rainfed conditions, few supplement the rains with irrigation, which is a good agronomic practice. In this study, pineapple fruit yield and quality (brix and weight loss) were assessed in rainfed and irrigated fields in Ghana’s Coastal Savannah agroecological zone in 2022 production period at Bomarts Farms. Forty (40) matured pineapple fruits from a 50 × 50 m plot were sampled under drip and rainfed conditions each. Weight of fruits were in the range of 609 g and 1,524 g inclusively. The average least fruit weight for drip-irrigated and rainfed fields were 652 g and 609 g, respectively. The variation of fruits weight under both conditions was not significant (p-value = 0.815). Generally, the weight loss was high in fruits from irrigated (drip) fields during the storage period. The brix for drip-irrigated pineapple was lower (12.8 0Bx, 15.6 0Bx and 19.8 0Bx) than pineapple cultivated under rainfed conditions (13 0Bx, 16 0Bx, 21 0Bx). Annual rainfall in the study area (840.7 mm) compared to requirement (1,000 mm) for pineapple plants poses a challenge to year-round production, and presents an opportunity for farmers to adopt good agronomic practices to sustain production in the coming years.

In this article we will use the approach and methodology of complex networks to analyze the territorial distribution of the public offer of secondary education in Asturias, based on the different population centers, which are the different nodes of the network, and the educational services that can connect them. Through the analysis of its structure and network topology, we will extract information that can be part of and incorporated into a complex socio-technological system that helps us understand the dynamics of Asturian territorial development. We will pay a special attention to the urban or rural nature of the nodes of the network and the implications in this regard that we can observe, due to the condition that the availability of the educational offer supposes for the development of the towns and their inhabitants. The results show a network with a scale-free topology that gives rise to consider possible alternatives that are more balanced from a territorial point of view.

Storage spaces are economic units where complex activities from reception-storage-delivery are carried out, with the aim of ensuring a constant flow of products downstream, in accordance with the food demand of people and of the animals. The aim of the paper is to analyze the main storage capacities in Romania, starting from general information collected from the Ministry of Agriculture and Rural Development (MARD) and National Institute of Statistics (NIS)database. The research methods used in this study have been the bibliometric analysis, the "bibliographic analysis" and the statistical-mathematical analysis for the calculation of averages by development regions and counties. Romania's agricultural areas are large, the soil and climate being favorable. However, the infrastructure is deficient, the number of operators dealing with the storage of agricultural production is high, but the average storage capacities are rather medium or small.Medium and long-term estimates show that Romania will also be affected by climate change, which leads to the conclusion that in order to keep harvests in optimal conditions and ensure constant production flows, important steps must be taken to develop this segment of activity.The researchers concluded that "storage is the key point of food security around the globe" because it ensures the preservation of products in sufficient quantities and of good quality. Romania's membership in the European Union made it possible to use the specific instruments of the Community Agricultural Policy, majorly influencing the agri-food market, increasing the value of services for agriculture. That is why funds were allocated that allowed our country to produce cereals in quantities that exceed the internal need, becoming one of the most important exporting countries in Europe.
