Display Field:
Type: Raster Layer
Geometry Type: null
Description: Goals:
To limit the environmental impacts of roads on Earth’s biodiversity, native ecosystems, and wilderness areas
To focus construction of new roads and road improvements where they will have the greatest social and economic benefits
To assist environmental managers to better plan and prioritize roads
To educate the general public about the environmental risks of poorly planned roads and transportation projects
Key facts about roads:
The 21st century is seeing an unprecedented expansion of roads
At least 25 million kilometers of new roads are expected worldwide by 2050—enough to circle the Earth over 600 times
90% of all road construction is occurring in developing nations, including many regions with exceptional biodiversity and vital ecosystem services
Roads penetrating into Earth’s remaining wildernesses are a major driver of habitat loss and fragmentation, wildfires, overhunting, and other environmental degradation
Much road construction is chaotic or poorly planned
Not all roads are environmentally detrimental
Roads or road improvements in areas where most native vegetation has already been removed, and where farming yields are low, can help to improve agriculture and local livelihoods with limited environmental costs
