Opis:
The aim of this study was to: a) show the place and role of cereals in the Polish economy in the early twenty-first century; b) analyze changes in the area of cereal crops and their share in the structure of crops in the years 1938-2013; c) analyze trends in the size and structure of grain production in the years 1938-2013; d) perform balance of cereals and determination of Polish self-sufficiency in this product; e) characterize trends in destiny cereals; f) present state intervention in the grain market. The analysis is based on sources such as scientific publications, reports of the Institute of Agricultural and Food Economics − National Research and statistical materials. The collected material was developed and interpreted using the methods: a comparison in the horizontal and vertical form, statistical form and determine the Polish self-sufficiency in grain production in terms of technical and economical Kapusta method. Cereals are an important component of agriculture and Polish economy since they are grown by 89.5% of farms, occupy almost three quarters of crop area and are an essential component of crop rotation (2013). 19.1% of global agriculture production and 35.5% of plant production and 13.1% of the agricultural commodity production and 29.1% of crop production form an important source of nutrients, the basis of the food pyramid and a basic component of food security, cereals and their derivatives are the subject of foreign trade and a source of increasing surplus in the trade balance (2012/2013 + 1 150 thousand euros). Already in pre- WWII Poland the position of grain was high, and in post-war Poland variable with a tendency to increase their role in plantings and agricultural production. Under the influence of various factors, mainly economic and natural there are changes to the total cereal cultivation area and the individual species. The universality of cereal crops makes difficulties in disseminating biological and technological progress. Although in the post-war period there was a decrease in areas planted with cereals, their collections are on the rise; also changes its structure in favor of more intensive species at a higher value in use (wheat, barley, triticale, corn). The production is realized in order to satisfy human needs, and therefore a good measure of the production of goods per 1 inhabitant, in this case the grain. From the pre-war years to modern years grain production has increased from 404 kg per capita to 739 kg. In the balance sheet of cereals at the beginning of the twenty-first century, we have two different situations; relatively stable internal consumption is accompanied by high volatility on the production side (changes in acreage and yields), which generates the need for imports in the years of crop failure. In Poland, cereals consumed (average of the years 2000 / 01-2012 / 13, for 13 years) are as follows: grazing − 60.5%, consumption − 22.2%, sowing (reproduction) − 7.2%, industrial processing − 4.5%, other (loss defects) − 3.7%. At the same time Poland exported 15,676 thousand tons of grain, and imported 16, 530 thousand tones, i.e. 854 thousand tons more. In subsequent years, however, there were changing trends in the balance of foreign trade in grain. In the period of Polish membership in the European Union we observe the increased foreign sales of grain and milk (both exports and imports). As a result of well-developed grain processing and export of its products Poland has achieved positive balance of trade with increasing surplus with foreign countries in terms of value for several years. The cereals market in Poland − as in other European Union countries − is regulated, and this action is led the Agricultural Market Agency on behalf of the state.

Opis:
The aim of the article was to define changes in recent trends in consumption of agri-food products in China against the other countries, as well as to analyse the food selfsufficiency in China in the years 2003–2013. The results showed that the consumption of particular agri-food products of both plant origin (with exception of cereals and starchy roots) and animal origin increased in China. But the rate in consumption growth of the latter was higher than in case of plant origin products. In fact, rising socioeconomic status in China enables its population to change diets towards patterns observed in developed countries, which means a growing demand for animal origin products. The analysis of food selfsufficiency showed that only in terms of fruit, vegetables and eggs China produced enough to satisfy its domestic needs. On other markets a lack of self-sufficiency was observed. Relatively biggest shortages of production were noticed for vegetable oils, milk and sugar.

Opis:
It has been 10 years of Polish membership in the European Union, and the acquisition of Polish agriculture rules of the Common Agricultural Policy. Such an anniversary induces us to reflect on the changes taking place in agriculture. The aim of the study was to: a) show the amount of funds paid to farmers under the Common Agricultural Policy and the sources of their origin, b) the presentation of changes in agriculture in terms of: inputs, crop area and production of major crops in total and per capita, livestock farming and the production of major animal products in total and per capita, productivity (land, labor and fixed assets), marketability and profitability (land and labor), self-sufficiency in the production and consumption: basic cereals, potatoes, cow’s milk, hen eggs, and meat and offal. As the base period for comparison one adopted the years 2001-2003, i.e. three years before the Polish accession to the European Union, and the last period is 2011-2013, due to the availability of validated statistical data. In agriculture, there are variations in the cultivation of various crops, animal husbandry and productivity of plants and animals caused by natural factors and economic considerations. There are also variations in the prices of means of production and the production itself. The adoption of three-year periods allows for the elimination of annual fluctuations and provides a more comparable performance. Poland moving to a market economy in the nineties of the twentieth century did prepare its whole economy to join the EU, especially in rural areas and agriculture. With the adoption of the EU there were Polish institutions and legal solutions allowing for the adoption of appropriate management and financial support directed to the country and to agriculture. This support contributed to the need to increase investment in agriculture also from national resources (co-financing). Finally, funding for agricultural production increased from less than 9% in the pre-accession period to 60% in 2009-2010. Appropriations for direct payments and complementary targeted at farmers account for about 61% of all funds directed to rural areas by the EU. In addition, Poland obtained without tariff barriers an access to the EU market, resulting in increasingly higher volumes of products and an increase in trade surplus. Obtained funding for farmers, the organization of the agricultural market and legal infrastructure stimulate multiple transformations in Polish agriculture, and the main ones are: –– Changes in the factors of production; reduction of arable land resources and the increase in capital assets and the change of their structure (reducing the share of buildings and structures and increase the share of machinery, equipment and means of transport). Labor resources have a high degree of stability to the amount due to the low possibility of their use in non-agricultural activities, while changes to the structure of these resources: increase the participation of young people, women and those with higher education. –– Changes in acreage of individual crops, harvest and production of plant products per capita. These changes are shaped by the market: demand and profitability of production, –– Changes in the size of herds of livestock (cattle, pigs, sheep, horses, poultry) and meat animal production. Here, too, very much evident operation of the market: demand and profitability of production. –– Increased economic efficiency: increase in productivity of all factors of production, –– Increased food self-sufficiency: food self-sufficiency ratios improved with increasing trade flows in agricultural products abroad. In conclusion, after encompassing Polish agriculture in the Common Agricultural Policy of the EU, there were a lot of structural changes in the factors of production, the organization of production, management efficiency and food self-sufficiency.

The article’s main objective is to discuss changes in self-sufficiency levels in cereal and potato production in eleven selected Central and Eastern European (CEE) countries belonging to the EU, defined as the ratio of domestic consumption of certain agricultural products to domestic production. The research period covered the years 2005 to 2019. The article focuses on the technical and economic self-sufficiency of the countries analysed. It was found that CEE countries show a significant degree of diversity in terms of self-sufficiency of cereal and potato production. The most successful in these terms were Lithuania and Poland while the least - Slovenia.

Opis:
Contemporary reality brings an abundance of changes. Some of them may be also observed with respect to forms of participation in culture. New models arise which follow the ideas of deinstitutionalisation, privatisation and self-sufficiency of viewers of culture. On the basis of these transformations, non-institutional actors appear who enter the role of educators, such as for example culture bloggers. Their activity features characteristics typical of educational turn in culture. They play a significant role in shaping cultural capital, while education remains an immanent quality of blogging about culture.

Opis:
The pursuit of energy self-sufficiency is understandable, as there can exist many reasons standing behind such pursuit. When considering commune level, many factors can influence the possibility of achieving energy self-sufficiency, but one thing is certain – this idea can be achieved by utilizing local renewable sources of energy, saving energy, and using it more efficiently. Such approach allows dealing with both climate change and energy crisis and can be beneficial for the local population, environment, and economy. The main aim of the work is to answer the question whether it is possible to achieve energy self-sufficiency on the communal level in north-eastern Poland. Five communes were analysed in terms of achieving both electric and heat self-sufficiency. We also checked whether there is an impact of selected municipal parameters on the value of energy potential of local energy sources. The results of our study indicate that achieving self-sufficiency is easier in terms of electricity (in 2 out of 5 communes the potential is more than twice as high as the demand) than in terms of heat (in 4 out of 5 communes the potential is more than twice lower than the demand, only in one the potential is close to the demand). It should be emphasized, that differences in the results obtained for different communes indicate that local factors have great influence on energy potential of individual communes.

Opis:
The aim of the article was to identify the spatial effects in assessment of financial self-sufficiency of the governments of communes (gminas) of Wielkopolska province (voivodship) in 2014, employing global and local Moran I statistics. The level of the governments’ self-sufficiency was examined by positional TOPSIS method. The study was based on publicly accessible databases compiled by the Ministry of Finance (Wskaźniki do oceny sytuacji finansowej jednostek samorządu terytorialnego) and the Central Statistical Office (Local Data Bank). Calculations were performed in R with packages spdep, maptools and shapefiles. The study demonstrated that the communes of Wielkopolska province of comparable levels of financial self-sufficiency exhibited a moderate tendency to cluster. Clusters of high levels gathered around larger urban centres, especially around Poznań, while clusters of low levels – in economically underdeveloped agricultural south-eastern and northern part of the province.

W Polsce coraz częściej dyskutuje się na temat samowystarczalności energetycznej. Wiele miast, gmin, związków gmin, czy też innych wydzielonych obszarów rozumianych jako strefa wspólnego działania, chce korzystać na dużą skalę z własnych zasobów energetycznych, przede wszystkim tych odnawialnych. Żeby właściwie opracować strategię rozwoju dla takich obszarów należy poprawnie zdefiniować pojęcie "obszar samowystarczalny energetycznie".
