Abstrakt	Wdrażanie rozwiązań z zakresu biogospodarki cyrkularnej jest zagadnieniem złożonym. Wymaga to dobrej znajomości koncepcji, różnych procesów gospodarki o obiegu zamkniętym i ich oczekiwanych skutków dla sektorów oraz łańcuchów wartości. Jednak badania nad gospodarką o obiegu zamkniętym wydają się być fragmentaryczne w różnych dyscyplinach i często istnieją różne perspektywy interpretacji tego pojęcia i powiązanych aspektów, które należy ocenić. Niniejszy artykuł zawiera przegląd literatury na temat biogospodarki i gospodarki o obiegu zamkniętym w celu lepszego zrozumienia tej koncepcji, a także jej różnych wymiarów i oczekiwanych skutków. Celem artykułu jest zarysowanie koncepcji biogospodarki o obiegu zamkniętym wraz z przedstawieniem głównych uwarunkowań jej wdrażania. Przedstawiono wybrane inicjatywy polityczne na rzecz wdrażania koncepcji gospodarki o obiegu zamkniętym w sektorze biogospodarki oraz modele biznesowe dedykowane dla rozwiązań biogospodarczych.
Abstract	Implementing circular bioeconomy solutions is a complex issue. It requires a good knowledge of the concepts, the different processes of the circular economy and their expected impacts on sectors and value chains. However, research on the circular economy appears to be fragmented across disciplines and there are often different perspectives on the interpretation of the concept and related aspects to be assessed. This article reviews the literature on bioeconomy and closed-loop economy to better understand the concept, as well as its different dimensions and expected impacts. The aim of the article is to outline the concept of a circular bioeconomy along with a presentation of the main considerations for its implementation. Selected policy initiatives for the implementation of the closed-loop bioeconomy concept in the bioeconomy sector and business models dedicated to bioeconomy solutions are presented.

Title	Supply of Materials to the Agribusiness Sector of European Union Countries
Słowa kluczowe	material supply, agribusiness, food industry, agriculture, European Union
Key words	material supply, agribusiness, food industry, agriculture, European Union
Abstrakt	The purpose of this paper was to assess the prevailing relationships in the supply structure of the agribusiness sector in European Union countries over the years. The study focused on 25 European Union countries (Cyprus, Luxembourg and Malta were excluded) to address the changes in the supply structures of agriculture and food industries, the two major components of agribusiness. The study was of a dynamic nature. Although the study period was 2000–2014, this paper only presents the figures for the first and the last year, i.e. 2000 and 2014. The main focus was on drawing conclusions on the trends observed which proved to be relatively stable in the years covered. The input–output analysis was used by aggregating the sectors of the economy for a better transparency of the inference process. As shown by this study, EU countries at higher development levels witness a decline in the share of the chemical industry in the mix of goods and services supplied to agriculture. Conversely, less developed countries saw that ratio increase. Also, the share of goods supplied to agriculture from the fuel and energy sectors goes up in most EU countries. As regards the food industry, this study observed high shares of agriculture, services and self-supply in the supply structure of EU countries. This analysis extends the existing knowledge on the relationships in the structure of materials supplied to the agribusiness because in addition to agriculture itself (which was addressed by similar studies found in literature) it takes account of the food industry. Moreover, based on long-term observations, it endeavors to capture the prevailing relationships in several countries at a time.

Tytuł	Ocena racjonalności działań inwestycyjnych w powiecie suwalskim w ramach wsparcia młodych rolników
Title	Evaluation of Machinery Investment Decisions Undertaken by Young Farmers in Poland’s Suwalki County
Słowa kluczowe	młodzi rolnicy, inwestycje, racjonalność
Key words	young farmers, investment, reasonableness
Abstrakt	Celem badań była ocena racjonalności doboru maszyn w ramach działań inwestycyjnych podejmowanych przez młodych rolników. Analizie poddano wyposażenie techniczne 54 losowo wybranych gospodarstw, których właściciele uzyskali wsparcie w ramach działań „Ułatwianie startu młodym rolnikom” lub „Premie dla młodych rolników”. Z przeprowadzonych rozważań wynika, że prawie połowa zakupów wozów asenizacyjnych była nieracjonalna pod względem ekonomicznym. Bardziej racjonalne pod względem organizacyjnym i technologicznym były inwestycje w ciągniki rolnicze i kosiarki dyskowe.
Abstract	The aim of the research was to evaluate the rationality of machinery selection within the framework of investment operations undertaken by young farmers. Technical equipment of 54 randomly selected farms, whose owners received support under the measures "Facilitating start-ups of young farmers" or "Bonuses for young farmers", was analysed. The conducted analyses show that almost half of the purchases of slurry tankers was economically unreasonable. Investments in agricultural tractors and disc mowers were more rational in terms of organisation and technology.

Title	Economic Efficiency of Table Grape Production in Waterberg and Sekhukhune Districts, Limpopo Province, South Africa
Słowa kluczowe	efficiency, farmers, table grapes, South Africa, stochastic frontier model
Key words	efficiency, farmers, table grapes, South Africa, stochastic frontier model
Abstrakt	Table grape production plays an important role in the economy of many countries in Africa. It serves as a source of income for the people who are engaged in its production and being one of the enterprises that is labour-intensive, thereby providing employment for more people. The main purpose of this study was to analyse the economic efficiency of table grape production in Waterberg and Sekhukhune Districts of Limpopo province, South Africa. The study used primary data collected through administration of structured questionnaires on a sample of 12 farmers by employing a snowball sampling method. Analytical tools employed include descriptive statistics (such as tables and frequencies), Stochastic Frontier Model and Technical Inefficiency Model.Results from data analysis revealed that in terms of efficiency, farming experience (p<0.01), educational level (p<0.05), household size (p<0.10) and age of farmer (p<0.10) were associated with increased efficiency indicating that these factors play important roles in ensuring that resources used in the production of table grapes enhanced productivity and were not wasted. Also, technical efficiency among farmers was found to range from 0.8 to 1, with a mean of 0.89, thus implying a major possibility for improvement in production. However, the allocative efficiency was found to range from 0.47 to 1, with a mean of 0.68. This indicates that some farmers were finding it difficult to allocate their resources efficiently. Again, economic efficiency ranges from 0.56 to 1, with a mean of 0.73, an indication that most of the farmers were economically efficient. Meanwhile, some of the constraints faced by these farmers include high electricity bills and labour costs, water shortages as well as instability around land policy. The study therefore recommends capacity building of farmers through education and other skill enhancement programmes. Also, provision of incentives to encourage youth participation in farming through internship programmes is very important to increase farm productivity.

Title	Genetically Modified Crops’ Technology and its Awareness among Smallholder Farmers in Nigeria
Słowa kluczowe	GMOs, smallholder farmers, awareness for GM crops, Credible seed sources, Agricultural technology
Key words	GMOs, smallholder farmers, awareness for GM crops, Credible seed sources, Agricultural technology
Abstrakt	Genetically Modified (GM) crops are crops modified through genetic engineering to improve their quality. Although safety concerns about genetically modified organisms (GMOs) are still being debated, the food security benefits have led to adoption by many counties. In Nigeria, where most farmers are uneducated and likely unaware of the agricultural technology, the government approved its first biotechnology crop for commercialization in 2018. Level of farmers’ awareness is crucial to acceptance of GM crops, although; this has not been fully explored in the literature. Therefore, this study aimed to assess farmers’ awareness for GM crops and the factors that determine their awareness in Oyo state, Nigeria, using primary data collected in 2018 with the aid of well-structured questionnaires from 242 smallholder farmers. Principal component analysis and Tobit regression model were used for data analysis. Results showed that farmers were aged 43 years with farm size of 3.57 ha, farming experience of 14 years and 11 years of education. Most farmers were male (71.90%), married (67.36%), not members of farmer groups (64.46%) and sourced their seeds from non-credible sources (85.12%). Most farmers (52.07%) had either not heard of or did not know of any benefits/costs of GM crops, hence; were not aware of GM crops. Factors that influenced awareness of GM crops were being a male farmer, years of education and source of seeds. The study concluded that increasing years of education and ensuring use of credible seed sources will increase awareness of the costs and benefits of GM crops among farmers.

Słowa kluczowe	embargo, Russia, apple market
Key words	embargo, Russia, apple market
Abstrakt	The article concerns the effects of the Russian embargo on apple producers in Poland. Scientific literature is quite poor in this field, mainly information articles in industry literature and media information are available. The literature was reviewed in this respect and two studies (questionnaire and interview) were carried out. The information obtained allowed us to draw conclusions about the very large negative impact of the embargo on the apple market and to learn about its characteristics. New markets do not generate sufficient demand, in 2018 apple prices dropped below production costs, but this does not reflect in a drop in prices in stores, which means that price speculations take place, and the situation is used by realtors. It is necessary to quickly return to the Russian market, because soon it will be unrecoverable for Polish fruit farmers. It is also necessary to put pressure on the European Union's policy, because nowadays it is the Polish farmers who bear its effects to the greatest extent.

Słowa kluczowe	czynniki produkcji, produktywność cząstkowa, produktywność całkowita, funkcja produkcji Cobba-Douglasa, gospodarka rybna
Key words	factors of production, partial productivity, total productivity, Cobb-Douglas production function, fish economy
Abstrakt	Badanie poziomu oraz tempa zmian poziomu produktywności poszczególnych sektorów umożliwia ocenę efektywności wykorzystywanych zasobów oraz identyfikację źródeł wzrostu produkcji. Obrazuje, w jakim stopniu poziom zmian w danej branży zależy od czynników pracy oraz kapitału. Celem opracowania jest określenie efektywności wykorzystania czynników produkcji w branży przetwórstwa rybnego w Polsce w latach 2005-2016. Do ustalenia tempa zmian efektywności czynników wytwórczych wykorzystano wskaźniki oparte na produkcji, zatrudnieniu oraz wartości brutto środków trwałych. Zaprezentowane badania wykazały, iż w branży przetwórstwa rybnego występowała generalna tendencja wzrostu produktywności pracy. Jednocześnie można było zaobserwować niekorzystne zmiany produktywności kapitału. Przeprowadzone badania wskazują, iż większy wpływ na poziom produkcji ma czynnik kapitału aniżeli poziom zatrudnienia. Ponadto wartość produkcji wzrastała w tempie szybszym niż łączne nakłady czynników ją kształtujących.
Abstract	The study of the level and dynamics of changes of productivity of individual sectors allows to evaluate possible effectiveness of the resources used as well as identification of sources of production growth. It shows the extent to which changes in the level of the industry is dependent on factors of work and capital. The aim of the work was to study the efficiency of production factors in the fish processing industry in Poland in the years 2005-2016. To determine the rate of changes of the efficiency of the production factors there were indicators used that were based on production, employment and gross value of fixed assets. The study showed that in the fish processing industry there was a general growth tendency of labor productivity. There were also observed adverse changes in capital productivity. The greater impact on the level of production has a capital factor than the level of employment. In addition, the value of production increased at a rate faster than the total expenditure of factors shaping it.

Słowa kluczowe	samopsza, płaskurka, uprawa
Key words	einkorn, emmer, cultivation
Abstrakt	Spośród uprawianych przez człowieka roślin, ze względów ekonomicznych i rolniczych zboża są najważniejszą grupą roślin uprawnych. Zboża, a zwłaszcza wyrabiany z nich chleb, są głównym i podstawowym produktem spożywczym na świecie. Pradawne gatunki oplewionych pszenic samopszy (Triticum monococcum) i płaskurki (Triticum dicoccum), od momentu ich udomowienia, stanowiły przez tysiąclecia podstawę diety człowieka. Było tak do momentu upowszechnienia się pszenicy zwyczajnej. W niektórych regionach świata są uprawiane do dzisiaj, a ze względu na rosnącą popularność zdrowej żywności rośnie ponowne zainteresowanie tymi dawnymi zbożami. Wiąże się to z dostosowaniem technik ich uprawy do warunków współczesnego rolnictwa konwencjonalnego i ekologicznego. W niniejszym artykule zostały omówione wyniki badań nad agrotechniką ekologicznej uprawy dawnych gatunków pszenic: samopszy i płaskurki. Pszenice oplewione są odporne na różne czynniki stresu biotycznego i abiotycznego i mogą być uprawiane w słabych warunkach glebowych, co zapewnia rolnikowi przewagę nad innymi uprawami. Daje to również producentom możliwość zagospodarowania niewykorzystanych nisz na rynku.
Abstract	Within plants grown by human being, in economical and agronomical point of view, cereals are the most important group of crops. Cereals, especially bread made of them, are major staple food in the world. For thousands years, from the moment of their domestication, ancient species of hulled wheats, like einkorn (Triticum monococcum) and emmer (Triticum dicoccum), were basic part of people diet. It was so until modern wheats (Triticum aestivum) became popular. In some world regions ancient wheats are cultivated nowadays. Adapting their farming techniques to modern agriculture and organic farming is related with increasing popularity of healthy eating. Results of organic farming techniques and cultivation research of einkorn and emmer are being presented in this article. Hulled wheats are tolerant to various biotic as well as abiotic stress conditions and can be grown in poor soil condition providing the farmer an advantage to take the crop. This also opens opportunities for manufacturers to seek the untapped market.

Title	Multidimensional Determinants of National Food Security in Azerbaijan: an Application of the ARDL Approach
Słowa kluczowe	food availability, food access, food stability, Azerbaijan
Key words	food availability, food access, food stability, Azerbaijan
Abstrakt	Food intake is a prerequisite for human beings to live a healthy life style. The attainment of food security is crucial and is a prime development priority for all developing countries. The inability to provide reliable evidence of national food security has remained a problem for both policymakers and researchers alike. The present study helps fill this gap by incorporating the multidimensional determinants of food security at the national level in Azerbaijan. The specific objectives of the study are to evaluate the short-term and long-term dynamics of these determinants on food security. The empirical analysis draws from nationally representative time series data over the period 1991 to 2018, taken from FAO and WDI. The ARDL model suggested that food import, exchange rate, inflation, climate change, and urban population growth harm national food security dynamics of Azerbaijan. On the other hand, trade to GDP ratio has a positive impact on food security. Overall results suggest that there is a pressing need to improve its institutional framework if the Azerbaijan government sincerely desires to have sustainable food security, as organizations control all other issues.

Key words
Abstrakt	The article systematizes the different views of scientists in relation to the anti-crisis management of enterprisesand emphasizes the importance of its use in enterprises. There was noted the necessity to introducethe perspective directions of economic activity of the enterprise, forming its image, ensuring competitiveness,profitability, and development. In order to make effective management decisions under uncertaindynamic environment, it is suggested to use fuzzy modelling for the prevention of the crisis occurrence.In order to present the possibility of using such an approach in the practical activity of agricultural enterprises,in particular which are engaged in dairy farming, we proposed an informational and logical modelfor determining the forecast average price of milk, taking into account the indicators of its quality, thatis based on the theory of fuzzy sets and fuzzy logic. In the context of anti-crisis management, there wassubstantiated the possibility of using the proposed model, as a basic one, in any agricultural enterprise inorder to improve its activities.

Abstrakt	W artykule zaprezentowano zmiany stanu wyposażenia obszarów wiejskich powiatu olsztyńskiego ziemskiego w systemy odprowadzania ścieków bytowych, ze szczególnym uwzględnieniem przydomowych oczyszczalni ścieków. Dane pochodziły z zasobów GUS-BDL. Obliczono udział ludności korzystającej z wodociągów i kanalizacji oraz zaprezentowano liczbę komunalnych oczyszczalni ścieków. Dane dotyczące przydomowych oczyszczalni ścieków i zbiorników bezodpływowych przeanalizowano na 1000 mieszkańców oraz na 100 km2 powierzchni. W wyniku przeprowadzonych badań stwierdzono, że wyposażenie w systemy odprowadzania ścieków rośnie. Szczególnie korzystnie rośnie liczba przydomowych oczyszczalni ścieków i nie spada liczba bezodpływowych zbiorników. Jest to wynikiem rosnącej liczby gospodarstw domowych i mieszkańców zwłaszcza w gminach otaczających Olsztyn.
Abstract	The purpose of the study was to evaluate, in a local approach, the state of supply of rural areas in a rural district with household wastewater management systems, with the focus on home wastewater treatment plants. The study covered the rural areas of the district of Olsztyn. The data, which were acquired from the Bank of Local Data, were processed through basic mathematical transformations and statistical measures. The structure and intensity indices were calculated per 1,000 residents. Large differences were found in the access to linear infrastructure and to individual systems of wastewater discharge. The results showed a constant increase in the number of home wastewater treatment plants and septic tanks due to the constant influx of people to villages lying around the town of Olsztyn. In contrast to studies conducted on a regional scale, no decrease in the number of septic tanks was observed correlated with the growing number of home wastewater treatment plants. A possible reason can be the specific environmental conditions and protection of inland waters, which limit possible locations of home wastewater treatment plants.

Tytuł	Zmiany dochodów indywidualnych gospodarstw rolnych z dzierżawy ziemi użytkowanej rolniczo w Polsce w latach 2005-2016
Title	CHANGES OF INDIVIDUAL FARMS INCOME OF THE AGRICULTURAL GROUND LEASE IN POLAND IN THE YEARS 2005-2016
Słowa kluczowe	dochód, ziemia rolnicza, rynek prywatny, dzierżawa, zmiany
Key words	income, agricultural land, lease, changes
Abstrakt	W ostatnich latach w Polsce rosną ceny ziemi rolniczej, a maleje jej podaż na rynku prywatnym. Sprzyja to rozwojowi zjawiska dzierżawy, która w wielu krajach europejskich jest podstawą prowadzenia działalności rolniczej. Celem opracowania jest charakterystyka dochodów otrzymywanych przez gospodarstwa indywidualne w Polsce z dzierżawy ziemi użytkowanej rolniczo i zmian dochodów w latach 2005-2016. Podstawę analiz stanowiły jednostkowe dane empiryczne, dane z badań sondażowych przeprowadzanych corocznie przez GUS, a ich uzupełnieniem były dane IERiGŻ-PIB, ANR (obecnie KOWR) i opracowania wtórne GUS. W wyniku badań stwierdzono, że dochody z dzierżaw prywatnych uległy podwojeniu w latach 2005-2016 i stanowiły ważny składnik dochodów korzystających z nich rodzin, ale z deklaracji badanych wynika, że miały one niewielką skalę (przeciętnie 0,3% gospodarstw indywidualnych). Grunty rolne były wydzierżawiane przez małe gospodarstwa, których głównym źródłem utrzymania była praca najemna, czasem za granicą, a kierownicy byli starsi niż przeciętnie. Często sytuacja rodzinna była nieuregulowana (np. starszy rodzic z dorosłym, ale jeszcze samotnym dzieckiem, które jeszcze ostatecznie nie zdecydowało o swej przeszłości), a okresowe wydzierżawienie gruntów pozwalało na podjęcie decyzji o ewentualnej sprzedaży gospodarstwa w późniejszym czasie.
Abstract	In last years, the prices of agricultural land in Poland have been rising, and the supply on the private market is decreasing. This favors the development of the lease phenomenon, which in many European countries is the basis for conducting agricultural activity.The purpose of the article was to characterize the income received by individual farms in Poland, from the lease of agriculture land and their changes in the years 2005-2016. The analysis was based of polls unitary empirical data, carried out annually by the Central Statistical Office, and supplemented by data of Institute of Agricultural Economics (IERiGŻ-PIB), Agricultural Property Agency (currently KOWR) and secondary studies of the Central Statistical Office. As a result of the research, it was found that revenues from private leases doubled in 2005-2016 and constitute an important component of revenues for families using them, but the respondents’ declarations show that they are small (on average 0.3% of individual farms). This is small farms, whose main source of income is wage labor, sometimes abroad, and managers are older than average. Often the family situation is unregulated (eg. an elderly parent with an adult but has not yet decided his past), and a periodic land lease allows for a decision on the possible sale of the farm at a later time.

Słowa kluczowe	polityka klimatyczno-energetyczna UE, odnawialne źródła energii, rynek biomasy rolnej
Key words	EU climate and energy policy, renewable energy resources, agricultural biomass market
Abstrakt	Aktualność problematyki podjętej w opracowaniu wynika zarówno z konieczności zwiększenia bezpieczeństwa energetycznego Polski, jak i jednoczesnej realizacji zobowiązań w ramach prowadzonej przez Unię Europejską polityki klimatyczno-energetycznej. Jednym z jej filarów jest wzrost znaczenia odnawialnych źródeł energii. Celem badań było określenie barier wynikających ze strony podażowej rynku biomasy rolnej w województwie łódzkim. Przeprowadzony wywiad kwestionariuszowy pozwolił na identyfikację kilku czynników niekorzystnie wpływających na rozwój rynku biomasy rolnej w województwie łódzkim, takich jak organizacja strony logistycznej odbioru surowca, opłacalność sprzedaży czy też brak dostępu do innowacyjnych rozwiązań.
Abstract	International cooperation on climate protection has very strong impact, which translates into increased interest in renewable energy, including biomass. Assuming the regional use of biomass, it may be an important source for energy, taking into account the need to reduce greenhouse gas emissions. The aim of paper was to identify the supply barriers for the agricultural biomass market development in Lodz province. In this case, information obtained from structured interview was used. The main barriers on the supply side include i.e. lack of organized transport, unprofitability of the sales/production, lack of knowledge and access to information about innovative possibilities of energy use of biomass.

Słowa kluczowe	pszczelarstwo, Wielkopolska, fundusze unijne, wsparcie pszczelarstwa
Key words	beekeeping, Wielkopolska, EU funds, support for beekeeping
Abstrakt	Poza dostarczaniem niezwykle cennych produktów, pszczoły są jednym z gatunków zdolnych do zapylania roślin entomofilnych. Stąd wspieranie rozwoju pszczelarstwa w obliczu ich znaczenia dla ludzkości wydaje się być niezwykle istotne. W Polsce zadanie to jest realizowane także przy użyciu środków pochodzących z Unii Europejskiej w ramach Programów Wsparcia Rynku Produktów Pszczelich. Celem artykułu jest zatem określenie roli środków pochodzących z Unii Europejskiej w rozwoju pszczelarstwa w województwie wielkopolskim na przykładzie Wojewódzkiego Związku Pszczelarzy w Poznaniu. Do badań wykorzystano niepublikowane dane WZP w Poznaniu, a także wyniki przeprowadzonej ankiety. Wyniki badań wskazują na pozytywne oddziaływanie środków z UE na rozwój pszczelarstwa w województwie wielkopolskim, zwłaszcza ze względu na spore zainteresowanie mechanizmem wśród pszczelarzy.
Abstract	In addition to providing extremely valuable products, bees are one of the species capable of pollinating entomophilic plants. Hence, supporting the development of beekeeping in the face of their importance to humanity seems to be extremely important. In Poland, this task is also carried out using funds from the European Union as part of the Bee Market Program Support Programs. The aim of the article is therefore to determine the role of funds originating from the European Union in the development of beekeeping in the Wielkopolskie voivodship on the example of the Provincial Union of Beekeepers in Poznań. First of all unpublished JPA data in Poznań, as well as the results of surveys were used for the research. The results of the research indicate a positive impact of EU funds on the development of beekeeping in the Wielkopolskie voivodship, especially due to the considerable interest in the mechanism among beekeepers.
