The IFLA WORLD 2025 congress in Nantes will take place in the context of global climate change, where adapting and building resilience in cities and territories requires profound and systemic transformations.
The profession of landscape architects plays a central role in these efforts, promoting urban approaches that prioritize living soils, biodiversity, and sustainable water management. It operates across all scales of metropolitan, agro-forestral, industrial or/and natural territories. It helps to anticipate environmental changes through participatory project approaches that make transformative dynamics accessible to inhabitants.
To support the transformation of territories, landscape architects develop nature-based solutions: to this end, they leverage all available sources of socio-environmental information, data systems and others digital tools. Combined with artificial intelligence, these tools now complement the survey and representation methods already at their disposal for their projects.
The IFLA WORLD 2025 congress is an opportunity to share best practices and insights from practitioners and researchers around the world, aiming to make the actions of landscape architects and associated professionals even more virtuous and effective.
