The aim of the paper is to determine the scale of intervoivodship variation in terms of the level of household income, taking into account the sources of this income. To evaluate regional differences related to the economic situation of households, the authors used data on the sources and level of income per person in a household in a voivodship. Average values of income for each identified source were calculated on the basis of microdata from the 2016 Household Budget Survey carried out by Statistics Poland. For the purpose of the study, the authors employed k-medoid method, one of non-hierarchical techniques of division. It was demonstrated that of all the diagnostic features adopted in the study, it was the level of income from permanent employment abroad which differentiated among particular clusters of voivodships to the largest extent. The average value for this feature in cluster 2 was PLN 5000,70 per person in the household. The performed grouping of voivodships showed that the extent to which households search for additional sources of income depends on the economic potential of the region and available opportunities.
Economic development requires following the principles of sustainable development for the socio-economic progress of a country. The organic farming sector is important in ensuring sustainable development. The advancement of organic farming is an important issue which combines the environment, human health and socio-economic development. It is a management method that facilitates supplying high-quality food products and aims at eliminating the use of artificial fertilisers and pesticides. Organic farming has a beneficial impact on natural environmental protection, biodiversity conservation and food safety and quality improvement. The natural conditions in a region have a decisive impact on organic farming development. The purpose of this study is to assess the spatial diversity of organic farming and selected organic crop production in Poland by voivodship in 2013 and 2018. The statistical analysis of organic farming spatial diversity was conducted in a one- and two-dimensional approach. The analysis conducted made it possible to identify four clusters of voivodships based on the production volume of selected organic crops using the k-means algorithm. Graphs of observation depth contours in a sample were used to visualise and to analyse the two-dimensional data. STATISTICA software and selected packages of the R environment, available under the GPL licence, were used in the analysis. The analysis shows that the organic farm number and acreage in Poland is characterised by considerable variability between voivodships, with their noticeable concentration in several country regions. In the analysed years, organic farming was the most widespread in the Warmińsko-Mazurskie Voivodship and the Zachodniopomorskie Voivodship.
Beekeeping is of great significance for the development of agriculture. On the one hand, it may be considered in the context of the acquisition of bee products by beekeepers, and on the other, in terms of the role bees play in the natural environment , i.e. their contribution to the production of higher and better crops. The aim of the paper is to present the beekeeping sector across Poland's regions and to describe the changes it underwent in the studied period. The research was conducted in 2012, 2016 and 2019. The study uses secondary data from reports produced by the Apicultural Division of the Apicultural Division of the Research Institute of Horticulture in Puławy that relate to selected issues concerning the beekeeping sector in Poland. The differences in beekeeping in different parts of Poland were subject to one- and two-dimensional analysis. The latter was performed using methods based on the measurements of the depth of observations in the sample. The research demonstrates that the number of bee colonies and the number of beekeepers were on the rise in the studied years. The largest number of bee colonies was observed in Lubelskie, Małopolskie, Podkarpackie and Warmińsko-Mazurskie voivodships, while the largest production of honey was registered in Lubelskie Voivodship.
