Description: Green Infrastructure refers to a planning and design approach that integrates natural processes to manage water, improve air quality, and provide ecological and social benefits. This concept encompasses a variety of elements, such as parks, gardens, green roofs, living walls, and sustainable drainage systems, which work together to create a healthier and more resilient urban environment. Green Infrastructure not only focuses on aesthetics but also aims to mitigate environmental issues such as water runoff, air pollution, and the urban heat island effect. By incorporating nature into urban design, biodiversity is promoted, the quality of life for residents is enhanced, and more efficient use of natural resources is encouraged. Additionally, this approach can contribute to climate change adaptation by reducing cities’ vulnerability to extreme phenomena such as flooding and heatwaves. In summary, Green Infrastructure represents an innovative and sustainable solution that combines technology and nature to address contemporary environmental challenges.
History: The concept of Green Infrastructure began to gain recognition in the 1990s, although its principles are based on planning and design practices that date back centuries. In 1992, the United Nations Conference on Environment and Development in Rio de Janeiro highlighted the importance of integrating nature into urban development. Since then, various initiatives and regulatory frameworks have been developed worldwide that promote Green Infrastructure as a key strategy for sustainable development.
Uses: Green Infrastructure is used in various applications, including stormwater management, the creation of recreational spaces, the improvement of air quality, and the promotion of biodiversity. It is implemented in urban environments to reduce runoff, filter pollutants, and provide habitats for wildlife. It is also used in ecological restoration projects and in the planning of sustainable cities.
Examples: Examples of Green Infrastructure include green roofs on buildings in cities like New York, which help reduce temperature and improve air quality. Another example is the sustainable drainage system in Portland, Oregon, which uses rain gardens to manage stormwater and prevent flooding. Additionally, the High Line Park in New York is an emblematic case of urban space reuse that incorporates vegetation and recreational areas.
