3 Policies Regarding CONSERVATION of World Heritage Properties
3.1 Protection, conservation and management of World Heritage properties
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.
Synthesis based on relevant Committee decisions
The World Heritage Committee recommends the States Parties to develop a long-term strategy for the sustainable financing of the property, and to ensure adequate human, material and financial resources to support the effective management (based on Case law on decisions on Nominations).
