Mitigation and engancement

If impacts are negligible, they may need no mitigation. In all other cases, mitigation should be considered to avoid or minimize any negative impacts (Section 6.3), and the revised proposed action together with its mitigation measures needs to be re-assessed (Section 6.8). This makes impact assessment an iterative process, with final predictions that include the planned mitigation measures.

A ‘mitigation hierarchy’ is often used in impact assessment, ranging from the preferred ‘avoidance’, through ‘minimize’, ‘rectify’ and ‘reduce’ to ‘offset’ (Figure 6.10). However, in the case of World Heritage, OUV is irreplaceable and cannot be ‘offset’. The best outcome for World Heritage is to avoid negative impacts entirely – this includes the dismissal of the proposed action, or its relocation away from the World Heritage property A cultural, natural or mixed heritage place inscribed on the World Heritage List and therefore considered to be of OUV for humanity. The responsibility for nominating a property to the World Heritage List falls upon the State(s) Party(ies) where it is located. The World Heritage Committee decides whether a property should be inscribed on the World Heritage List, taking into account the technical recommendations of the Advisory Bodies following rigorous evaluation processes.
When used as a general term, World Heritage refers to all the natural, cultural and mixed properties inscribed on the World Heritage List. . However, it may involve creative problem-solving to re-think and potentially redesign the proposed action or identify measures that avoid negative impacts. In some cases, it may not be possible to entirely avoid all negative impacts but they should be minimized to acceptable levels that cause no concern for World Heritage by significantly reducing their magnitude, duration, extent, etc.

Once mitigation measures have been identified, it is important that they are included in the revised proposed action, which should then be re-evaluated. Any residual negative impacts – those impacts that would still affect the World Heritage property A cultural, natural or mixed heritage place inscribed on the World Heritage List and therefore considered to be of OUV for humanity.

Further mitigation measures may be needed. If significant residual negative impacts on OUV cannot be avoided, the impact assessment report should recommend that the proposed action should not be taken forward.

While avoiding negative impacts is at the heart of impact assessment, best practice in impact assessment takes a more proactive and positive approach: proponents should not only aim to ‘do no harm’, but seek to actively ‘do good’ while not compromising OUV. The commitment of States Parties The countries that have ratified the World Heritage Convention The Convention Concerning the Protection of the World Cultural and Natural Heritage is an international treaty adopted by the UN in 1972 that defines the kind of natural or cultural sites which can be considered for inscription on the World Heritage List for their Outstanding Universal Value for all humankind. Commonly known as the World Heritage Convention, it establishes how the international community as a whole is responsible for
the protection of such heritage and sets out the duties of States Parties in identifying potential sites that may be eligible for inscription onto the World Heritage List and their role in protecting and preserving them. By signing the Convention, each country pledges to conserve not only the sites situated on its territory that have been recognized as being of Outstanding Universal Value, but also to protect its national heritage and to be involved in international efforts to protect, conserve and promote the heritage of humankind. . By ratifying the Convention, States Parties commit themselves to undertake actions directed to:identifying, knowing, protecting and promoting the cultural and natural heritage located on their territories;adopting a general policy aiming to give their cultural and natural heritage a function in the life of the community;integrating the protection of that heritage into comprehensive planning programmes;setting up services for the protection, conservation and presentation of the cultural and natural heritage with an appropriate staff and possessing the means to carry out their functions;developing scientific and technical studies and research to counteract the dangers that threaten their cultural or natural heritage;taking the appropriate legal, scientific, technical, administrative and financial measures necessary for the identification, protection, conservation, presentation and rehabilitation of their heritage;
• fostering the establishment or development of national or regional centres for
training in the protection, conservation and presentation of their cultural and
natural heritage;encouraging scientific research in this field.As members of the international community and while respecting the sovereignty of each State, States Parties to the Convention also recognize their duty to collectively contribute to the protection of the properties inscribed on the World Heritage List. Therefore, upon request by other States Parties to the World Heritage Convention The Convention Concerning the Protection of the World Cultural and Natural Heritage is an international treaty adopted by the UN in 1972 that defines the kind of natural or cultural sites which can be considered for inscription on the World Heritage List for their Outstanding Universal Value for all humankind.

Once inscribed, States Parties assume the primary responsibility for the protection of those properties and to do all they can to achieve this purpose. They are also requested to report periodically on the state of conservation of those properties as well as on the provisions they have adopted to implement the Convention. to integrate a sustainable development perspective into all World Heritage All inherited assets that people value for reasons beyond mere utility. Heritage is a broad concept and includes shared legacies from the natural environment, the creations of humans and the creations and interactions of humans and nature. It encompasses built, terrestrial, freshwater and marine environments, landscapes and seascapes, biodiversity, geodiversity, collections, cultural practices, knowledge, living experiences, etc. processes (Section 3.4) means that impact assessment offers an opportunity to enhance the positive impacts of a proposed action, or create new ones, for the benefit of both heritage and society (see Box 6.6).

The proposed action may also be able to reduce the impact on the World Heritage property A cultural, natural or mixed heritage place inscribed on the World Heritage List and therefore considered to be of OUV for humanity. The responsibility for nominating a property to the World Heritage List falls upon the State(s) Party(ies) where it is located.

The section of the impact assessment report containing mitigation recommendations should become a living document that can be used by all parties as the project moves through different stages of implementation, even by those who were not involved in the original impact assessment. This ensures that mitigation measures are understood and implemented by all and can be monitored.
The impact assessment needs to clearly state:

• which mitigation and enhancement measures are necessary in order to sustain OUV and other heritage/conservation values
• who should carry them out
• the timeframe for completion.

In most cases, the proponent will be responsible for these actions. The impact assessment recommendations should be provided in a form that can be readily incorporated into an implementation strategy (Section 6.14). For example, they might become part of the commitments made by a project proponent, or used by the relevant authorities to set mandatory conditions for approval which the proponent is obliged to adopt when permission is granted. They should be clearly stated, measurable and binding. To help ensure that mitigation and enhancement take place as required, the impact assessment report should show clear connections between the recommendations and the subsequent steps of decision-making, implementation of the proposed action, and monitoring (Figure 6.11).
