Mangroves and the associated shoal forest known as ‘restinga' are ecosystems of great ecological relevance that play a significant role in the protection of the coastline in tropical regions. In Brazil, the coastal region has been severely affected by urban expansion. The Paranaguá Port, located in Paraná State (Brazil), is the fourth most important Brazilian port in throughput, and is located in an estuarine region which features large mangrove forests. An historical assessment of its inner access channel dredging rates was made to assess the impacts that the expansion of the Port in the last 30 years may have caused to the ecosystem. In the following, the historical data concerning the dredged volume in the inner access channel was compared to the mangrove and the shoal forest associated variation, aiming to establish a potential correlation between vegetation and siltation in the inner access channel to show as the preservation or restoration of specific ecosystems has potential to Nature-Based Solutions.

Emission of harmful substances into the atmosphere resulting from the combustion of fuels in the energy production process and road traffic intensity are a key determinants of poor air quality in cities and the creation of an unfriendly environment for people to live in, which has a significant impact on their safety and health. The first step to reducing emissions is to reduce energy consumption. The ecological effect resulting from the thermal modernization of existing residential building stock was estimated. Nature-based solutions were proposed to compensate for the lost green areas in favor of gray infrastructure in the form of green roofs and walls. The possibility of improving environmental conditions by introducing this type of solutions into the urban tissue was assessed. Depending on the type of vegetation, one m2 of green cover is able to absorb an average of 2.3 kg of CO2 and 0.2 kg of particulate matter from the air per year. Renewable energy sources are an important element of green buildings. Heat pump may be the most advantageous solution in minimizing emissions combined with low operating costs. Obtaining energy from geothermal sources would be equally beneficial in terms of reducing emissions, but there are risks changes in groundwater levels or soil damage. Solar energy is one of the leading renewable energy sources, especially in hot water installations, where it is possible to reduce energy consumption by up to 50%.

Zadrzewienia śródpolne stanowią kluczowy element zielonej infrastruktury obszarów wiejskich. Szczególnie ważne jest ich systemowe kształtowanie. Celem artykułu jest wskazanie znaczenia procesu scaleń gruntów jako narzędzia umożliwiającego rozwijanie sieci zadrzewień będących elementami zielonej infrastruktury na obszarach wiejskich. W artykule zaprezentowano koncepcje: zielonej infrastruktury, rozwiązań opartych na naturze oraz usług ekosystemowych w kontekście obszarów wiejskich w Polsce. Przedstawiono funkcje zadrzewień śródpolnych oraz scharakteryzowano potrzeby zadrzewieniowe w Polsce. Odniesiono się do obecnych praktyk projektowych dotyczących zadrzewień i zakrzewień śródpolnych w założeniach do projektów scaleń gruntów. Przedstawiono nowe możliwości w tym zakresie, związane z interwencją pn. „Scalanie gruntów wraz z zagospodarowaniem poscaleniowym”, realizowaną w ramach Planu Strategicznego dla Wspólnej Polityki Rolnej na lata 2023-2027.

Mid-field trees are a key element of green infrastructure in rural areas and their planting should be strategically and systematically planned. The aim of the article is to show the significance of land consolidation process as a tool enabling the development of a network of field trees as an element of green infrastructure in rural areas. The article presents the concepts of: green infrastructure, nature-based solutions and ecosystem services in the context of rural areas in Poland. The functions of field trees were presented and the needs in terms of field trees planting in Poland were characterized. Reference was made to the current planning practices applied with regard to field trees and field shrubs in the drawing up of land consolidation plans. New possibilities in this respect were discussed, related to the intervention entitled "Land consolidation with post-consolidation management", implemented under the Strategic Plan for the Common Agricultural Policy for the years 2023-2027.
