In Belém, Brazil, urban greening has become essential for improving the quality of life. Since 2022, the Municipal Environment Secretariat has planted over 8,000 tree seedlings, featuring 68 species that contribute to environmental enhancement. This effort aims not only to beautify urban spaces but also to combat climate change, improve air quality, and promote community well-being.
A recent debate held by local authorities, including the Emílio Goeldi Museum and the Federal Rural University of Amazonia, focused on the urban greening process, highlighting the importance of scientific research in selecting appropriate species for the region's climate and soil.
Kayan Rossy, director of the Public Green Areas Department, emphasized the need for meticulous planning in tree planting. He warned against unauthorized planting, as inappropriate species can cause infrastructure damage. Trees are vital for regulating microclimates, reducing temperatures, and improving air quality.
Additionally, urban trees play a crucial role in preserving biodiversity. According to ecologist Marlúcia Martins, trees support pollinators and enhance food security. They provide fruits and flowers that attract various wildlife, reinforcing the ecological chain and the city’s cultural identity.
Significant tree planting locations include major avenues and public squares, with the Ipê Rosa, Pau Preto, and Mangueira among the most commonly planted species. These initiatives are critical as urban areas expand, with projections indicating that 70% of the global population will reside in cities by 2050.
Meanwhile, in Italy, the National Tree Day on November 21 saw students engaging in tree planting activities, underscoring the vital role of trees in urban ecosystems. Celebrated by Legambiente, the event highlighted trees' functions in combating climate change and improving urban resilience.
