Green areas
What is the difference between green areas and sealed or dark surfaces?
Urban sprawl and the gradual replacement of the natural environment by building materials such as cement and asphalt have created several problems in the urban environment. These materials absorb and retain heat, contributing to higher temperatures in urban areas. In addition, they prevent rainwater from seeping into the ground, leading to increased runoff and possible flooding. Finally, they create inhospitable environments for plants and animals, thus reducing biodiversity.
On the contrary, green spaces in cities provide important environmental benefits, such as improving air quality by filtering pollutants through trees and plants and providing natural cooling, thus mitigating the urban heat island effect, making cities more comfortable, and reducing energy consumption. They improve water management by facilitating the absorption of rainwater, thus reducing flooding and improving water quality. Urban greening maintains biodiversity by providing habitats for various species and contributing to carbon sequestration, playing an important role in mitigating climate change. These benefits underline the importance of integrating nature into urban design for healthier and more sustainable urban environments.
What techniques make houses, villages and towns greener?
- Covering the roofs and exteriors of buildings with plants for air purification and insulation
- Use sustainable and environmentally friendly materials such as recycled wood, bamboo, and green concrete for lower environmental impact
- Rainwater harvesting for irrigation
- Creating communal green spaces and gardens in the buildings by planting edible plants for food, aesthetics, and community enhancement
- Using native plants to support local wildlife and increase biodiversity
Collaboration between architects, urban planners, and residents is key to successfully incorporating these green elements into buildings, considering local climates, regulations, and maintenance needs.
