The agri-food sector in Romania is of particular importance for the market economy, referring to agriculture, food industry, commerce, and not ultimately the final consumer. Due to changes in consumer behavior of agri-food products, it is increasingly desirable to know the food traceability, the concept from farm to fork being constantly developing. In the context of ensuring food security, it is important to have an efficient monitoring of the food route in order to keep it fresh. An important factor in this process is the new communication and information technologies, which are in continuous development especially from the applicative point of view. This paper aims to support the producers and suppliers of fresh agri-food products in order to improve management at the short supply chain by exemplifying some types of computer tools that can be used in their work. The conclusion was that GIS maps and GPS location enable the use to know where production is located and the storage conditions.

In the efforts to develop a sustainable, low carbon, resource efficient and competitive economy and ultimately the green economy in the European Union, circular economy is an important conceptual and practical approach with essential contribution. Latest developments in eco-innovation in Romania are those dedicated to implementing the circular economy, as a way to increase the waste recycling and the resource productivity (one of the lowest in the European Union). In this respect, the main objective of the paper is a theoretical and methodological grounding and analysis of some concepts, trends and issues required for the implementation of the green economy in the EU and Romania, as well as for the sustainable regional economic development. The role of creating and developing ecoindustrial parks, namely eco-innovation parks EInvP is not limited on their potential of increasing the resource efficiency but also to implementing and making work the new modern synergic and circular business models. In the paper we shall refer to some successful and pioneering circular economy enterprises or industrial eco-systems working in Romania, as good practices and pilot projects. The conclusions and recommendations refer to the importance of spatial eco-innovation represented by the industrial symbiosis as a high form of circular economy.

An important issue to be tackled is that the Romanian Small and Medium-sized Enterprises (SMEs) are less likely to adopt measures to improve their resource efficiency in comparison to the EU average and have a low propensity to collaborate for a systemic transformation agenda such as the circular and green economy. The main research objective of this paper is to stress eventually the strategic role of eco-innovation in developing eco-industrial parks as a community of manufacturing and service enterprises seeking enhanced environmental and economic performance through collaboration in managing environmental and resource issues including energy, water, and materials. The methodological approach will be based mostly on some own recently published theoretical and empirical research findings, referring to a case-study as well. The main results and conclusions outline the urge to identify, design and plan the possibilities of industrial symbiosis between several enterprises within an ecoindustrial park as a way for promoting green development in the SME-s as well as at the local, regional and macroeconomic scale.

Overtime, land values have continued to diminish due to unsustainable land management practices engaged by the farmers. This study evaluated the econometric analysis of agricultural land values in Imo State, Nigeria. Multi-stage random sampling technique was used to select 75 farmers for the study. Information on the objectives of this study was elicited from the sampled respondents through a well structured questionnaire and interview schedule. Data were analyzed using descriptive statistical tools, and multiple regression models. The socio-economic features of the farmers reveal a mean age of 58 years, 12 years educational attainment, 5 persons per household, 15 years farming experience, and a mean farm size of 1.07. Results further showed that Owerri zone recorded the highest land values across the zones, the land values (Ha/farmer) from the zone was N278, 193.52 which is considerably higher than other land values obtained from Orlu and Okigwe zones respectively. Double-Log function was selected as the lead equation and was used to interpret the factors influencing land values across the three agricultural zones in the State. Hence efficient land management practices such as (organic manuring, crop rotation, alley cropping, etc.) were recommended for the farmers to improve land value in the area.

This study focused on economic structure of different beekeeping farm sizes in Isparta province in Turkey. The main material of the study was comprised of original data acquired by way of survey method from 74 farms in Isparta province which carry out beekeeping activities. Neyman Method from among the stratified sampling methods was used for determining the number of samples that will be subject to surveys. Accordingly, the farms with 0-75 hives (31 farms) group I, farms with 76-150 hives (25 farms) were classified as the group II whereas farms with 151+ hives (18 farms) were classified as the group III. Gross production value per hive ranged from 254. to 271.54 USD and on average it was 267.32 USD. The share of honey sale was approximately 99% of the total gross production value. The lowest and the highest production cost per hive were 49.12 to 71.58 USD, respectively. The result showed that as the magnitude of farm size increased, production costs per hive declined. It means that bigger farms had advantages over small farms in terms of production costs per hive. It was determined that permanent labor and feeding costs played an influential role in total production costs. The proportion of permanent labor cost in total production cost for group I, group II, and group III was 42.36, 37.94, and 33.62 %, accordingly, and feeding costs comprised 32.01, 28.51 and 35.71 %, respectively, of total production cost. Gross profit per hive ranged from 180.21 to 240.42 USD and on average it was 235.77 USD. In addition, net profit per hive increased as farm size increased. Relative return is a criterion that measures the success of a commercial enterprise. Relative return for group I, group II and group III were 3.55, 4.96 and 5.48, respectively. Since the relative returns of all the farm groups were higher than 1 it can be concluded that all the farms were profitable in relative returns increased with the increase in farm size.

The objective of this study was to carry out an economic comparison of different types of cold storage facilities for apple. Primary material of the study was comprised of original data acquired from cold storage facilities in Isparta province which is ranked number one in Turkey in the field of apple storage. Analyses were carried out by classifying the enterprises into three groups according to their cold storage types as those with normal atmosphere (NA), those with controlled atmosphere (CA) and those as cold storage facilities with a mixture of normal and controlled atmosphere (NA+CA). It was determined that the average capacities were 7,500 tons, 4,540 tons and 2,400 tons, respectively for NA+CA, NA and CA facilities. Capacity usage ratio was determined as 85.42% for CA facilities, 79.74% for NA facilities and 77.60 % for NA+CA facilities. It was determined that Golden Delicious ranked first among the apple types stored in all cold storage types. It was determined that the ratio of Golden Delicious among the apples stored in the facilities was 52.49 % for NA, 52.89% for NA+CA and 69.86 % for CA facilities. NA+CA facilities were determined to have the highest average annual operating cost among the examined facilities. Average total cost per enterprise among NA+CA facilities was determined as 355,869 USD, 192,131 USD for NA facilities and 121,282 USD for CA facilities. When the enterprises were compared with regard to net income per ton, it was observed that CA cold storage facilities were more profitable. Net income per ton was calculated to be 27 USD for CA facilities, 21 USD for NA+CA facilities and 17 USD for NA facilities. It was determined that total costs and total income were equal and that break-even point was reached when 41.62% of the capacity is used for CA cold storage facilities, 43.94% for NA+CA facilities and 45.75% for NA facilities. Facilities make profit after this point.

Post-harvest straw deserves particular attention among agricultural raw materials. It can be intended for sale, applied as litter material in animal husbandry or used in field fertilization. To a lesser extent it can be used for fodder production, covering mounds of roots and tubers and the production of insulation materials in horticulture and building construction. Using surplus straw directly for energy generation, including production of pellets and briquettes, should also be considered rational. Several applications were analyzed. The main purpose of the research is to determine the profitability level of winter wheat cultivation and of energy use of the straw obtained. Among others, they included situations in which obtained straw was used in the production of pellets, in fertilization after prior grinding and mixing with manure or used for direct sale. For our calculations, the costs/ha of wheat cultivation and then straw collection were estimated. The comparative analysis of various options of wheat straw utilization shows the highest profitability in the option of selling the straw and mineral fertilization.
