Maintaining good condition of dam reservoirs in urban areas seems increasingly important due to their valuable role in mitigating the effects of global warming. The aim of this study is to analyze possibilities to improve water quality and ecosystem condition of the Paprocany dam reservoir (highly urbanized area of southern Poland) using current data of the water parameters, historical sources, and DPSIR (Driver–Pressure–State–Impact–Response) and 3D modeling concerning human activity and the global warming effects. In its history Paprocany reservoir overcame numerous hydrotechnical changes influencing its present functioning. Also, its current state is significantly influenced by saline water from the coal mine (5 g L⁻¹ of chlorides and sulphates) and biogenic elements in recreational area (about 70 mg L⁻¹ of chlorate and to 1.9 mg L⁻¹ Kjeldahl nitrogen) and in sediments (222.66 Mg of Kjeldahl nitrogen, 45.65 Mg of P, and 1.03 Mg of assimilable phosphorus). Concluding, the best solutions to improve the Paprocany reservoir water quality comprise: increasing alimentation with water and shortening the water exchange time, restoration of the 19th century water treatment plant, and wetlands and reed bed area revitalization. The study also proved the applicability of mathematical models in planning of the actions and anticipating their efficiency.

Objectives: Industrially contaminated sites (ICS) represent an important public health issue in European countries. The Silesian Voivodeship, the region located in the southern part of Poland, the historical center of industry, has many sites that meet ICS criteria. Most of them are landfills...

Agriculture and rural regions in Europe face a number of economic, social, and environmental challenges. Rural areas are active players in the EU’s green transition. Weeding is one of the most important factors in agricultural production. New weeding techniques are being developed to enhance sustainability. Among them, laser-based weeding seems to be a promising alternative to the use of chemicals. The WeLASER technique is a novel technique for weed control. Its successful implementation depends on many factors related to the innovation itself, policy context, farming conditions, and users’ attitudes. A survey was carried out to provide insight into the attitudes towards the innovative (laser) weed control tool (autonomous robot). The CATI method was selected for the surveying of farmers’ opinions and carried out in three countries: Denmark, Spain, and Poland. Statistical methods were applied to analyze the results. This study provided knowledge on how farmers see the barriers and opportunities related to implementing the device in practice. Positive attitudes of farmers were observed but with high expectations related to the quality of the technique and the systemic conditions of its implementation.

Climate change adaptation has become a central policy priority, requiring coordinated and systematic action. Cities, as areas highly exposed to climate-related risks, increasingly assume responsibility for implementing effective adaptation measures. In this context, municipalities are required to incorporate Urban Greening and Rainwater Management Concepts into their Climate Adaptation Plans. This paper presents a structured methodology for developing these strategic concepts as components of a City Adaptation Plan, in accordance with recent legislative mandates in Poland. Through case studies conducted in two Polish cities, we demonstrate an integrated approach that combines geospatial analysis, climate projections, planning document review, and participatory stakeholder workshops to produce comprehensive Greening and Rainwater Management Concepts. The methodology enables the identification of vulnerable areas and priority interventions for climate adaptation, strengthens the integration of nature-based solutions into urban planning, and reframes rainwater as a resource within urban systems. The resulting documents provide municipal authorities with an evidence-based framework for resilience planning, supporting funding applications and guiding future green infrastructure and drainage investments. The approach contributes to enhanced urban ecosystem services, improved flood mitigation and thermal regulation, participatory planning processes, and a stronger foundation for long-term urban resilience.

In the digital age, spatial databases are the main source of information on the hydrographic network. However, the main challenge remains the need for frequent updates alongside the accurate presentation of current and potential coverage. Modern geo-information tools based on the processing of remotely sensed materials allow precise modeling of places where reservoirs historically occurred or are predisposed to form. The restoration of reservoirs is significant in the context of flood protection, the improvement of retention conditions, and the development of blue-green infrastructure. It is also much more economically viable than preparing sites for new construction. The missing element in the systematic use of the aforementioned materials and tools for these purposes is methodology. For this reason, in this article, based on images and a point cloud acquired during a photogrammetric aerial flight, five methods are tested, and the most effective method is identified, depending on the intended application.
