Climate changes are affecting the nature of our area. Green-blue infrastructure should be part of the concern for preserving biodiversity. It offers a chance for positive changes – it can contribute to increasing water retention, protecting soils, and preserving places in the landscape that are friendly to organisms. Valuable natural sites are our local heritage. Their protection is an action that supports the protection of water resources, increases air humidity, reduces runoff, maintains good living conditions, and healthy outdoor activities. In these articles, we want to emphasize four priority goals necessary for the preservation of nature around Pobiedziska, as well as fitting into the green-blue assumptions of spatial management of the city and municipality. Caring for nature is also about caring for a conscious local community and a good future for all of us.
WATER – MULTIGENERATIONAL RESOURCES?
Water is a resource that cannot be overestimated – it is essential for the proper functioning of the environment, society, and economy. Recently, it has become a source of social unrest – we fear both droughts and floods, expecting constant availability and high quality. What challenges do we face, and what can we do to improve the quantity and quality of water resources in our area?
Attempt to Restore the Natural State
One of the best methods for improving water resources is renaturation. It is a very economical method, as it is largely carried out by ceasing current activities, such as cleaning, deepening drainage ditches, and straightening the riverbed. In our area, the ideal river for renaturation is the Główna River. In its valley, it would be necessary to move away from close construction, lead to the restoration of its ecosystems, such as meadows and riparian forests (forests with ash and alder), which would become a zone protecting the river from pollution and the influx of fertilizing substances in further sections. The undeniable benefits of this process on a larger scale include: (1) carbon sequestration in the soil, which contributes to climate protection, (2) stopping the runoff of nitrates and phosphates, which prevents eutrophication and blooms of waters (including the improvement of the water quality of Kowalskie Lake), (3) slowing down water runoff and increasing retention, (4) improving the microclimate, which would reduce the risk of drought in agriculture and fires, (5) increasing the biodiversity of disappearing species of animals, fungi, and wetland plants.
