The primary objective of a CHIA is to identify and assess the potential impacts of a proposed project on cultural heritage resources, such as archaeological sites, historic buildings, and traditional cultural practices.

Natural landscapes are not typically considered cultural heritage resources, although they may have cultural significance to certain communities.

Stakeholders play an important role in the CHIA process by providing input on the scope and methodology of the assessment, reviewing and commenting on the CHIA report, and assisting in the implementation of mitigation measures.

Common mitigation measures used to address potential impacts on cultural heritage resources include relocation of cultural heritage resources, preservation in situ, documentation and recording, and public education and awareness.

Cumulative impacts can result in the loss of cultural heritage resources over time, can be more severe than individual impacts, and can be difficult to predict and assess.

The Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict provides a framework for the protection of cultural heritage during armed conflict.

Indigenous knowledge and traditional ecological knowledge can provide valuable insights into the cultural significance of resources, help identify potential impacts on cultural heritage resources, and contribute to the development of mitigation measures.

Archaeological excavation is not typically used for documenting cultural heritage resources during a CHIA, as it is a destructive method.

Public participation can help identify cultural heritage resources that may be impacted by a project, provide input on the significance of cultural heritage resources, and help develop mitigation measures that are acceptable to the community.

The precautionary approach in CHIA involves all of the above principles: when there is a threat of serious or irreversible damage to cultural heritage resources, lack of full scientific certainty should not be used as a reason for postponing measures to prevent or minimize such damage, the burden of proof lies with the proponent of the project to demonstrate that the project will not cause significant harm to cultural heritage resources, and mitigation measures should be implemented to minimize the risk of harm to cultural heritage resources.

A Cultural Heritage Management Plan (CHMP) serves all of the above purposes: to outline the measures that will be taken to protect cultural heritage resources during a project, to provide a framework for monitoring and evaluating the effectiveness of mitigation measures, and to establish a process for resolving disputes related to cultural heritage resources.

Positive impacts, such as increased awareness and appreciation of cultural heritage, are not typically considered to be impacts that development projects may have on cultural heritage resources.

Regulatory agencies play all of the above roles in the CHIA process: they review and approve CHIA reports, enforce compliance with cultural heritage legislation, and provide guidance to project proponents on CHIA requirements.

Intangible cultural heritage can provide insights into the cultural significance of tangible cultural heritage resources, can be impacted by development projects even if there are no physical impacts on tangible cultural heritage resources, and can contribute to the development of mitigation measures that are sensitive to cultural values.

All of the above are common challenges in conducting CHIA: lack of data on cultural heritage resources, difficulty in assessing the significance of cultural heritage resources, and resistance from project proponents to implementing mitigation measures.
