Nature-based solutions involve harnessing the power of nature to address some of the most pressing societal challenges, such as the threat of natural disaster risk or the effects of climate change. These solutions generate responses to environmental problems along with multiple other benefits.
Buenos Aires City has promoted several measures applying this initiative, such as the construction of linear meters of pipelines in water courses and the development of an early warning system to prevent major floods in the event of heavy rainfall.
We intend to generate greater water retention capacity and reduce urban heat islands. That is why we created green roofs which contribute to regulating housing temperatures by reducing energy demand, and increasing biodiversity. In 2019, the new Building Code of the City was approved, it contemplates the implementation of green roofs, walls and curtains as well as vertical gardens. These green coverings and the solutions based in the environment, slow down the speed of stormwater runoff, and delay its arrival in the network, a factor of great importance during heavy rainfall when the stormwater system must absorb large amounts of water in a few minutes. They also filter dust and pollution, and improve the City's air quality.
Many times people who live and/or work in the City do not get to interact with the watercourses because many of them are piped. Therefore, we intend to promote the opening of piped streams in each basin, facilitating the interaction of the groundwater with the watercourses. The areas for temporary retention of surplus water we are going to expand or implement include:
The Area for Temporary Retention of Surplus Water (ARTEH) of the Medrano Basin (Parque Sarmiento).
The ARTEH of the Cildañez Basin (Parque Indoamericano).
The creation of new ARTEH in other water basins.
Did you know that we reached 3,380 m2 of green roofs in school buildings, which is equivalent to approximately 13 tennis courts?
