This article reviews the production capacity of Polish agriculture with respect to biomass used for energy production. The forecast production potential of agricultural biomass in Poland in 2020 includes three key areas: the expected consumption of renewable energy according to energy type, the energy potential of agriculture and barriers to the use of biomass. Studies have shown that in Poland, total energy consumption will significantly increase (over 10% by 2020). Growth of demand for renewable energy will primarily result from strong growth of demand for transport biofuels and electricity. In 2020, approximately 80% of final energy from renewable sources will come from biomass. More than three-quarters of the biomass will be generated from agriculture. In Poland, crops from 1.0 to 4.3 million ha can be used for energy production. The study shows changes in the structure of biomass use, and the analysis confirms the declining share of biomass for heat production and the increasing share of biomass for electricity and biofuels. The main obstacles to the continued use of agricultural biomass are a lack of local markets for biomass energy and poor financial support for energy crop production

In many circles, brown coal continues to be viewed as a cheap source of energy, resulting in numerous investments in new opencast brown coal mines. Such a perception of brown coal energy is only possible if the external costs associated with mining and burning coal are not considered. In past studies, external cost analysis has focused on the external costs of coal burning and associated emissions. This paper focuses on the extraction phase and assesses the external costs to agriculture associated with the resulting depression cone. This paper discusses the difficulties researchers face in estimating agricultural losses resulting from the development of a depression cone due to opencast mineral extraction. In the case of brown coal, the impacts are of a geological, natural-climatic, agricultural-productive, temporal, and spatial nature and result from a multiplicity of interacting factors. Then, a methodology for counting external costs in crop production was proposed. The next section estimates the external costs of crop production arising from the operation of opencast mines in the Konin-Turek brown coal field, which is located in central Poland. The analyses conducted showed a large decrease in grain and potato yields and no effect of the depression cone on sugar beet levels. Including the estimated external costs in the cost of producing electricity from mined brown coal would significantly worsen the profitability of that production.

The purpose of this study is to calculate the externalitiesfor the agriculture and the agri-food industry ofplanned open-cast lignite mining on the Oczkowice reserve.The mine’s area of impact extends to 7 districts of south-westWielkopolska. The study envisages 2 options for the depressioncrater’s impact (mine dewatering) on crop productionand 2 scenarios of losses in livestock production. Losses dueto unrealized production in the agricultural and agri-food sectorswithin a 100-year time horizon (50 years of mining and50 years for hydrological recovery) are estimated to rangefrom PLN 22.4 billion to PLN 174 billion. Externals costs, definedas lost profits, are estimated to range from PLN 5.1 billionto PLN 39.5 billion. Compared to the value of lignitefrom the Oczkowice reserve, the level of external costs andproduction losses in the agricultural and agri-food sectorsmake open-cast lignite mining at that location an economicallyunviable project.

The main aim of this paper was to assess the impact of socioeconomic and agricultural factors on cow and pig density in suburban areas located up to 50 km from the 11 biggest cities in Poland. This study relied on data retrieved from all municipalities located within 50 km from central cities. The impact of the previously mentioned socioeconomic and agricultural factors was assessed using the Pearson correlation coefficient, analysis of variance (ANOVA), and regression analysis. This study shows that the lowest cow and pig density was recorded in the two inner rings. From 1996 to 2010, the gap between them and the levels recorded in other rings became much more pronounced. The analysis only corroborated the high correlation between livestock (cow and pig) density and the share of corresponding livestock farms in the total number of farms as well as the average herd size. Regarding other agricultural and socioeconomic factors, the correlation was weak or low except for a moderate correlation between the entrepreneurship indicator and pig density. The regression analysis demonstrated that the share of cow and pig farms in the total number of farms, average herd size, residential housing density, and unemployment rate had a significant impact on the density of animal groups considered.

In many circles, including in Poland, lignite is still viewed as a cheap source of energy, which is only possible if the external costs associated with mining and burning coal are not taken into account. In Poland, this is reflected in plans to open new Złoczew opencast lignite mines. In previous studies, the analysis of external costs has focused on the external costs of coal combustion and related pollutant emissions. This paper focuses on the extraction phase. The aim of the work here described was to estimate the external costs that agriculture may incur due to the formation of a depression funnel for the projected lignite mine in the Złoczew deposit. This paper discusses factors causing uncertainty in calculated estimates of external costs in agriculture, and characterizes the Bełchatów and Złoczew opencast mines. In the paper, a methodology for calculating external costs in livestock production is then proposed. In the next part of the study, the decrease in cereal and potato yields and in the number of cattle and pigs in the area of the cone of depression of the Bełchatów opencast mine, which has been in operation for 40 years, were estimated. The estimates obtained formed the basis for estimating external costs for the planned Złoczew lignite opencast. The analyses showed high external costs for plant production and much lower for animal production. The inclusion of the estimated external costs of 12.2 € × kWh−1 in the costs of electricity production will significantly worsen the profitability of launching this opencast. The paper discusses factors causing uncertainty in calculated estimates of external costs in agriculture, and characterizes the Bełchatów and Złoczew opencast mines. The discussion also shows that the level of losses incurred in crop production due to opencast coal mining is similar to the losses incurred in crop production in extremely dry years.
