“Biodiversifying” the Fight Against Climate Change

Moderated by: Jérôme Spaggiari, Atelier Phusis
Adapting to climate change

- Greening our buildings for the sustainable development of the urban environment and communities

Urban development is putting increasing pressure on the viability of natural environments which directly compromises the quality of living environments. Issues such as urban heat island effect, storm water management, and the loss of biodiversity and ecosystemic services are evidence of this. However, the deployment of strategies such as those related to the greening of buildings help mitigate the negative effects caused by these problems. The purpose of this conference is to demonstrate how greening the building is one of the sustainable solutions that address the major environmental and socio-economic challenges of today's and tomorrow's communities. It is therefore in a spirit of openness to collaboration that two passionate phytotechnology specialists unite to carry out an integral presentation combining the global study of the fallout and the practical application of these structuring means.

- Revegetation of hostile sites by environmental microbiology in response to climate change

Current revegetation techniques for disturbed sites do not provide the most effective atmospheric carbon sequestration scenarios. Revegetation with woody plants on human-disturbed sites is used to increase carbon sinks through the photosynthetic mechanism as well as actinorhizal root symbiosis for the reconstruction of fertile forest humus. Thus, a technology that can restore the fertility of a hostile and contaminated soil and establish the ecological succession of plants is essential to meet this need. In Canada and around the world, our mission is to manage and address the challenges of planting in a hostile environment, to generate carbon credits from plantations, and to counteract the effects of climate change by providing innovative and forward-thinking solutions in the field of revegetation.

- Freedom space for rivers: a climate change adaptation approach

Bank erosion and flooding are natural phenomena that could increase due to climate change, resulting in potential land use conflicts near rivers. Frequent engineering interventions such as bank stabilization or flood protection are traditionally required to protect infrastructure or maintain agricultural land use near streams. However, there is a growing consensus among practitioners and researchers that fluvial processes must be left free to operate and that hard-engineered solutions against floods and bank erosion should not be the only solution. Giving more space to rivers to restore natural processes appears as a more sustainable solution in terms of both risk management and environmental protection. Details and examples of theses kinds of new practice will be provided, and the recent work done in Quebec to identify and map this « freedom space » for rivers will be presented and discussed.
