Citizen Sense leads an air-quality walk at the Barbican
Air pollution is a major issue environmental public health in many cities throughout the world. While reducing emissions at the source is the best way to address air pollution, vegetation can play an important role in mitigating air pollution. Trees and plants can capture particulate matter, absorb gaseous pollutants, and phyto-remediate soils. In addition, vegegation can enhance biodiversity, capture stormwater and reduce flooding, and lessen the urban heat island effect.
Plants are organisms that are
continually sensing and changing our environments. The Citizen Sense research
group has developed the term ‘Phyto-sensor’ to describe these vegetal processes
whereby plants sense, respond and contribute to environments.
