3 - Policies Regarding CONSERVATION of World Heritage Properties
"21. [The World Heritage Committee] (u)rges States Parties, with the support of the World Heritage Centre and the Advisory Bodies, to:
a) Incorporate well-designed buffer zones based on a holistic understanding of natural as well as human induced factors affecting the property, supported by reinforcing relevant legal, policy, awareness and incentive mechanisms, into new nominations and where appropriate into existing properties to ensure enhanced protection of World Heritage properties,
b) Place particular emphasis on strategic environmental assessment and impact assessments for potential projects within buffer zones to avoid, negative impacts on OUV from developments and activities in these zones,
c) Develop buffer zone protection and management regimes that optimize the capture and sharing of benefits to communities to support the aspirations of the 2015 Policy for the integration of a Sustainable Development Perspective into the processes of the World Heritage Convention,
d) Ensure buffer zones are supported by appropriate protection and management regimes in line with the property’s OUV, that build connectivity with the wider setting in cultural, environmental and landscape terms."
