3 Policies Regarding CONSERVATION of World Heritage Properties
3.5 Factors affecting properties
3.5.2 Transportation infrastructure
Conservation of cultural and natural heritage is at the core of the Convention. Conservation includes effective and active measures that can be taken by States Parties to ensure the identification, protection, presentation and transmission of heritage.
There is no single definition of conservation in relation to both cultural and natural heritage. However, with regards to cultural heritage ‘all operations designed to understand a property, know its history and meaning, ensure its material safeguard, and, if required, its restoration and enhancement’ could be part of its conservation (Nara Document on Authenticity). Conservation of natural heritage refers to the protection, care, management and maintenance of ecosystems, habitats, wildlife species and populations, within or outside of their natural environments, in order to safeguard the natural conditions for their long-term permanence (IUCN).
The Conservation theme includes policies related to protection, management, monitoring, impact assessments, factors affecting the properties, tourism and sustainable development.
The physical 'footprint' and derived effects of use (includes visitor transportation infrastructure).
Ground transport infrastructure (For example: Roads, Car parks, Railways, including easements). Air transport infrastructure (For example: Airports, Airstrips). Marine transport infrastructure (For example: Harbour & port facilities). Effects arising from use of transportation infrastructure (For example: Effects of vehicle traffic on roadways, Effects of shipping traffic in shipping routes, Effects of air traffic).
