The urbanisation of the Belgian territory and the fragmentation of green and blue spaces have negative consequences on the environment: animal species that cannot access feeding or nesting sites, migratory routes cut off, reduced surface area of ​​natural habitats, etc. The extension of the green and blue network in Belgium will provide concrete ecological and socio-economic solutions, particularly with regard to climate change, loss of biodiversity, water management, soil erosion and air pollution.

Belgium has a high ecological footprint. Its dense population, its specific production and consumption patterns and its high volumes of imports, exports and transits exert significant pressure on biodiversity. This pressure extends beyond Belgian territory because Belgium is a major importer of raw materials and products. This results in a loss, fragmentation and degradation of natural habitats and ecosystems, such as forests, savannahs, wetlands, mangroves, rivers. To ensure the sustainability and resilience of the various economic sectors, it is imperative to change Belgian consumption and production patterns. Taking into account the impacts on biodiversity is crucial. This change will be beneficial and will improve biodiversity in Belgium and abroad.
