Growing environmental and climate problems in the contemporary world necessitate the search for efficient solutions, including changes in agriculture, which has been reflected in the new package of reforms of the EU climate policy, called the European Green Deal (the EGD). Agriculture and rural areas play an essential role in the attainment of the EGD goals, and one of the prerequisites for an effective implementation of the EGD assumptions is to recognize the mechanism underlying the activity of agricultural farms in the scope of pro-environmental measures implemented under the Common Agricultural Policy (CAP). This article presents an endeavour to make a multidimensional evaluation of the spatial diversification in such activities, using Polish farms as an example. Compared to other EU member states, Poland is a country where agriculture remains a substantial sector in the national economy. This research is based on data from several institutions, including the Central Statistical Office (CSO) and the Agency for Restructuring and Modernisation of Agriculture (ARMA), responsible for the allocation of funds from the EU budget and for providing support to the development of agriculture and rural areas. The level and structure of the absorption of funds from the CAP underwent analysis, including three pro-environmental measures of the Rural Development Programme: organic farming (OF), agri-environment climate measure (AECM), and afforestation and creation of forest areas (ACFA). In order to achieve a holistic approach to these measures, an innovative analytical model was developed. It can be applied to analyses on a regional, national, and European level, and it is based on several novel indicators, as well as advanced statistical and spatial analyses. The research demonstrates that the pro-environment activities of farmers are characterized by a significant geographical diversity. The most active in soliciting payments from the CAP were agricultural farms with a high level of pro-environment internal characteristics of agriculture (IPEAF = 30.1%, with national average = 11.6%). With regard to anthropogenic determinants, relatively higher values of the IPEAF indicator were found in the municipalities with a lower level of socio-economic development (12.1%) and those located in northern and western Poland, within the borders of the former Prussian Partition (18.6%), characterised by higher farming culture. The research results imply that the effectiveness of the up-to-date solutions needs to be improved, also by taking into consideration the endogenous conditions and potential of individual territorial units. The research results also prove the expediency of implementing the European Green Deal. Conducting an analysis of the pro-environmental activity of farms, taking into account both the applications of the current CAP financial perspective and those resulting from follow-up activities regarding the previous perspective, is an innovative approach to the issue.

Public transport has undergone major changes in recent years. In particular, they relate to the issue of environmental impact. Due to the significant emission of pollutants from the economy, in particular from the transport segment, member states of the European Union have taken measures to limit its scope. Only low-emission and zero-emission vehicles are to be used in transport, and mainly those that are powered by electricity in public transport. The development of battery technologies has led to a revolution in the range and operational capabilities of electric buses in the last decade. They have become a seemingly easy alternative to traditional electric vehicles in public transport—trams and trolleybuses. This article presents the possibilities and limitations of the development of public transport in Poland based on electric buses. An attempt was made to review the literature and compare the possibility of the functioning of buses, trams and trolleybuses in the Polish socio-economic, environmental and technological conditions. The article was based on a literature query, an analysis of unpublished materials, and a qualitative analysis of national programs endorsing the idea of electromobility as well as an online survey on the perception of electric public transport. The main goal of the article was to identify and evaluate the possibilities of developing public transport in Poland with the use of electric buses. The main results of the work include the demonstration that the optics of the national and regional authorities in Poland are focused mainly on electric buses without a thorough analysis of the legitimacy of their operation, especially in small towns. The incentive in the form of subsidizing the purchase of an electric bus is sufficient for them, and the future effects of using electric buses are not investigated.

The present study attempts to examine the research gap in terms of comparing the environmental impact of trolleybuses and diesel buses in the conditions of a country with an unfavourable energy mix. The analysed example concerns the trolleybus transport system in Gdynia, in northern Poland, which also partially serves the neighbouring city of Sopot. In the last few years, two bus lines have been electrified with trolleybuses in the In-Motion-Charging technology, which enables operation on sections without an overhead network. Using the actual operational data, a comparative analysis of the emissivity of diesel buses and trolleybuses used on the same lines in an identical operating regime was conducted. Moreover, an attempt was made to estimate the damage costs of the emission of air pollutants for the above-mentioned means of transport. Research has shown that trolleybuses significantly help to reduce emissions of nitrogen oxides, non-methane volatile organic compounds and particulate matter, while increasing sulphur dioxide emissions on the served lines. They also generate lower specific emissions of carbon dioxide compared to diesel buses. However, taking into account the differences in the number of seats in these vehicles, the length of routes resulting from a need to provide access to the necessary infrastructure and the total amount of kilometres covered on a given route, they may cause higher emissions per year and per the product life cycle than diesel buses. This is related to the unfavourable structure of energy production in Poland, which is dominated by coal sources. The research results clearly show that the use of trolleybuses in public transport contributes to a reduction of the damage costs of the emission of pollutants that amount to approximately EUR (€) 30,000–60,000 per year for the analysed lines.

Soil erosion is one of the major processes degrading the natural environment but also agricultural production areas. Soil erosion may lead to soil organic carbon (SOC) loss, especially from sloping agricultural terrain units. The use of phytomelioration in environmental management, particularly long-term, permanent forest vegetation, is widely recognized as a possible measure for soil erosion protection and mitigation of climate change through carbon sequestration. The aim of this study was to compare of the topsoil organic carbon stocks on the slopes under soil-protecting forests in relation to the adjacent agricultural slopes. The research was conducted in the young glacial landscape of North-Central Poland. The study indicated the significant role of forest management on the increase of soil organic matter content and SOC stock. The results show that land use and slope gradients are important factors controlling soil organic carbon pools in topsoil in young glacial areas. This topic is extremely important particularly as the effects of climate change become more and more visible, and society faces new challenges in preventing these changes.
