Environmental flow is the amount of water that must flow in a river to meet the water needs of aquatic and water-dependent ecosystems. It is an important criterion for water management - the value of environmental flow is determined by the nature of the river, the organisms living in it and the hydrological conditions.

Green walls (green walls) are innovative solutions that improve air quality, regulate microclimates and increase biodiversity in cities. The article, based on experience in Turin, describes a project of two green walls with a total area of 300 m², implemented as part of urban revitalization.

Extreme temperatures are becoming an increasingly serious challenge for urban areas, and the implementation of urban heat island mitigation strategies faces numerous difficulties. Using the example of Wuhan, China, this paper analyzes the ability of urban greenery to cool urban areas in the context of actual stress conditions, such as road density, traffic intensity, building density and height, and the proportion of impervious surfaces.

Urban greenery improves the quality of life in cities by regulating temperature and humidity, biofiltrating air pollutants, reducing noise, and creating spaces conducive to relaxation and recreation. Unfortunately, urban conditions not only negatively affect the condition of plants, but also limit their ability to perform ecosystem services.

From April 30 to June 27, SGGW will participate in the Biodiversity Challenge for ICA Members 2025 as a member of the ICA Network, which is co-hosting this event organized by Wageningen University and Research, the Netherlands. You are welcome to participate!

Our latest publication analyzes the hydrological conditions of Great Snipe (Gallinago media) breeding sites in Poland. Our research, conducted in Podlasie, Lublin and Zamojszczyzna regions, on 16 dubelta toking sites, showed that the most important factor affecting the number of males on the breeding sites was the lowest groundwater level during the breeding season. In short, the drier the worse.

Does the joy of fireworks come at a price? Researchers from the University of Gour Banga, Malda, West Bengal, and the SGGW Centre for Climate Research teamed up to find out. In a joint study, they monitored air quality during two major holidays: Diwali in India and New Year's Eve in Poland.

An international collaboration of scientists from the Centre for Climate Research and Gour Banga University in Malda, West Bengal, India, has uncovered alarming facts about microplastic pollution in landfills, a major environmental threat in India.

Research conducted on the green roof of the Warsaw University Library has revealed the great potential of plants in cleaning urban air of particulate matter (PM). The team analyzed dust accumulation on eight different plant species, taking into account seasonal variation.

Research in Wuhan, China, has shown that shrubs and herbaceous plants effectively remove particulate matter and heavy metals from the air, making them a valuable component of strategies to improve air quality during the winter. In optimizing urban greenery for effective air purification in autumn and winter, consideration of biodiversity should be key, as different plant species differ in their efficiency in collecting different pollutants and in their filtering activity at different times of the year.
