5.10.1
Why monitor?

As stated at the outset, the fundamental task of heritage managers is to ensure that heritage places are conserved so that current and future generations can experience and benefit from it, both now and well into the future. Since heritage places evolve over time to adapt to new demands and circumstances, it is necessary to track changes in order to assess whether their heritage values are being maintained. The only way to know this is by assessing the ‘health’ of the attributes that convey and embody those values.

Monitoring a heritage place is therefore a long-term systematic process of collecting and analyzing data to gather insights about the state of conservation of the attributes as well as their likely future. This involves assessing whether contextual and ecological conditions are changing, whether rates of physical deterioration are stable or increasing, and if there is loss or reduction of certain elements or characteristics, in terms of size, numbers, frequency, functions or distributions.

Monitoring also involves tracking the outputs of actions taken on the basis of the management plan. Outputs are measures of productivity resulting from the implementation of planned actions, routine work and management processes. Different types of outputs can be expected across the management cycle which can include:

  • plans and/or strategies, policies, and instruments resulting from planning process;
  • physical works carried out on the ground;
  • material products or goods produced;
  • volume of work and activities undertaken;
  • data and information derived from management processes;
  • services provided.

One main advantage of monitoring is to detect signs of problems at an early stage, in order to take preventive actions. For example, when monitoring the condition of a defensive wall in an historic settlement, signs of bulging will likely prompt maintenance works or light repairs. Likewise, when trying to control a particular invasive species, monitoring its distribution will allow managers to know when they will need to deploy more people to manually remove it before it spreads too much. These examples show how monitoring can avoid larger problems in the future.

Monitoring also helps detect changes that are only or generally noticeable over long periods of time. Comparison of photographic material helps to understand the melting of glaciers over the past decades and how this problem is increasing because of higher average temperatures and other climate change effects. Monitoring is also important to identify other slow changes such as urbanization of green spaces, densification of urban areas or deterioration of the physical fabric due to wind erosion or pollution.

Some changes become apparent through the combination of data such as the total area of uncultivated plots in a cultural landscape, the number of secondary residences in an historic village, or the total number in species population combined with the number of development permits issued. Through the analysis of these data, managers can evaluate the extent and severity of the problem and identify the most appropriate actions based on the information available.

A good monitoring programme will also facilitate other monitoring processes and reporting requirements. Local communities, governments and donors need to be kept informed of how resources are being used and that expected results are being achieved. Monitoring can also help identify challenges that require additional funding. High quality data will help convince decision-makers and donors of the importance of a project. However, monitoring and reporting should not be confused.
Whereas reporting is a ‘snapshot’ taken at a moment in time, monitoring the state of conservation is a systematic, continuous process, the main purpose of which is to help managers in their daily work. The information generated through this process can and should be used to facilitate reporting obligations but being aware of this fundamental difference is critical. Otherwise, there is a risk that monitoring is only carried out for reporting purposes, reducing the advantages it offers, when used properly, as a sort of alarm system.

5.10.2
How to design an effective monitoring programme?

A monitoring programme to assess the state of conservation of a heritage place needs to provide answers to two questions:

  • what is the state of the attributes and the trends in condition?
  • is it necessary to take action and, if so, when?

In order to answer these complex questions a monitoring programme needs to be designed and it will need to be reviewed over time. The art of developing such programmes involves selecting a few indicators that capture as much information over time as possible about the state and trends of the attributes, without costing too much time or money to monitor. Although well-selected and welldefined indicators are one of the key elements of an effective monitoring programme, monitoring is more than a collection of appropriate indicators.

Figure 5.7 A step-by-step process for developing a monitoring programme

Use attributes as a basis for monitoring: A monitoring programme for a 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.
should focus on its OUV and specifically on its attributes, while also recognizing other heritage values and attributes of the place. A monitoring programme which focuses on specific attributes is more likely to detect changes in the condition of important attributes before it is too late. This manual has already discussed the identification of heritage values and attributes that also need to underpin good monitoring programmes (see 3.1).

Since the number of attributes of a heritage place may be quite extensive, it is likely that decisions will need to be made about which ones to monitor; otherwise, there is a risk of designing a monitoring programme that is too complex and too costly and which, therefore, might not be used. Identifying which attributes to focus on requires a thorough understanding of all the attributes, their interlinkages and the range of values they convey, in order to make a selection of those that will help gather the best information about the overall health of the heritage place. It is also necessary to understand the factors affecting the heritage place and how they impact (or could potentially impact) the attributes.

Develop a set of indicators for attributes and outputs: Once there is a clear understanding of what needs to be monitored, it is necessary to start defining how to monitor it and when active management measures may be needed. The next step involves defining a set of indicators that will monitor the condition of the specific attributes selected. For example, indicators to monitor an endangered species might be the breeding population size, or the extent of its habitat, whereas for a historic village the indicator might be the size of resident population or number of abandoned houses if changing demographics is a main factor affecting the property.

Monitoring indicators may also be based on collecting the outputs delivered from implementing the actions, such as reduction in visitor numbers due to a revised access route. This type of output indicator can also provide valuable information about management needs and the impacts on the attributes of the property.

It is better to focus on a smaller number of critical indicators that are clearly linked to the most important attributes of the heritage place and to measure them well and consistently. This allows resources and time to be given to priorities, rather than attempting to monitor too many indicators badly. Indicators might need to be chosen on the basis that they can be measured over time to provide specific quantitative or qualitative information related to the attributes of the heritage place. Indicators should:

  • have a clear, predictable and verifiable relationship with what is being assessed;
  • be able to measure or capture changes in the condition of what is being assessed;
  • reflect long-term changes rather than short-term or localized fluctuations;
  • be able to identify current problems as well as detect new ones;
  • focus on changes that will have direct implications for conservation and management;
  • be cost-effective in terms of data collection, analysis and interpretation;
  • be simple to measure and interpret;
  • be easily understood by non-specialists.

Agree on indicator thresholds: It is important to define indicator thresholds; these are the clearly defined points at which the measurements of an indicator show that there are changes in condition which require action. This is particularly important to detect when things are going wrong. Monitoring alone will not help protect a heritage place if it does not prompt action when necessary.

Thresholds should be determined as much as possible for each indicator, along with indications of the likely preventive responses if those thresholds are crossed. Conservation efforts should aim at keeping the condition of the attributes, and by default, the indicators, within acceptable ranges of variation in order to preserve a healthy status over the long-term. Furthermore, a precautionary approach should be used to ensure early and timely action to prevent irreversible impacts. For example, if the 20% threshold of abandoned houses is exceeded in a historic town, this will signal there can be potential problems such as increased risks of fires or collapse or decreased security. It may also be a sign of social change, depopulation or declining economic conditions.

Identify response to a threshold being crossed: If those thresholds are crossed, action is required. Managers need to know what to do if such situations occur, both in terms of trying to tackle the underlying cause, as well as having management responses to the potential new problems that have arisen.

Develop monitoring protocols: A good monitoring programme will also detail the monitoring protocols for each indicator, that is, the methods that will be used to collect data (e.g. sampling, interviews, surveys, observations), the frequency of data collection (e.g. monthly, quarterly, annually), as well as information about who will be responsible for collecting the information and the material and equipment needed.
The frequency of monitoring should be based on the robustness or fragility of the attributes, their susceptibility to change and the factors affecting their state of conservation. Therefore, frequency may need to change if the situation changes. 

Develop a data management system: Data collected will need to be compiled into a data management system to facilitate analysis and inform conservation and management decisions. This is particularly important if different data collection methods are used and if different departments or units (sometimes, even different organizations) are involved. Sometimes, problems become apparent only by cross-referencing the data collected.

The choice of data collection methods and technologies should be informed by the financial and material resources available, as well as by human capacity. In many cases, simple and inexpensive monitoring methods will be sufficient and more reliable. In other cases, modern technologies may be needed and can offer cost-effective solutions. In all cases, non-destructive data collection methods should be preferred.

Establish a baseline: A baseline is a set of data describing the attributes which provides a starting point against which comparisons can be made in order to assess if conditions are stable, are improving or are getting worse. Baseline references for the state of conservation may be documentation (e.g. photographs, laser scans, etc.), or they may be the qualitative or quantitative status of the indicator, such as the population count of an endangered species, or a description of the conservation conditions of an abandoned building.

Monitoring of World Heritage properties should take as a baseline the conditions at the time of inscription in order to compare changes over time. However, if the property is already in a fragile state of conservation at the time of inscription, then the desired state of condition of the attributes should be identified. While the state of conservation of a property should never become worse than it was at inscription, management actions should support improvement in the condition of the attributes.

Monitor against the baseline: Once the monitoring programme has been defined, it is important that the monitoring activities take place according to the established protocols. Institutional commitment to monitoring is fundamental and it should be seen as an essential part of management responsibilities.
Monitoring is an ongoing activity and needs constant and long-term investment.

Since monitoring can be costly, effective monitoring programmes can be built on partnerships between managers and other actors, such as universities. In such cases, the monitoring programme should still respond to management needs as a priority over academic research agendas. A well-designed data management system is critical so that managers have easy access to the data collected and in formats that will facilitate their work.

Use monitoring data to inform management decisions: Interpreting data collected from a monitoring programme and using it to inform management decisions is probably the most difficult part of monitoring the state of conservation of the heritage place. Posing these simple questions may help:
Does the data point to a small or big change in the condition of the attributes or the factors affecting that condition?
What is the trend of that change? Is that change in the desired direction (for example, a decrease in the number of vacant buildings in an historic settlement or an increase in the number of uncultivated fields in a cultural landscape, or a reduction of the areas affected by an invasive species, or an increase in the population of an endangered species)?
If the trend is in the opposite direction to the desired one, why is that happening? Were the management measures implemented insufficient or is more time needed to see the full effect of those measures? Are additional measures necessary? What adjustments are needed?

Managers need to understand the changes occurring and reflect on whether the management measures put in place are generating the expected outcomes, detect what is working and what is not, and any unanticipated consequences of those measures. In this way, managers can correct the measures taken or devise new ones that are more efficient.

Make adjustments based on lessons learned: Monitoring programmes will be imperfect when first developed, particularly since the correct information is not always immediately available. Therefore, it is critical to periodically review and improve them based on lessons learned and as experience is gathered. Improvements may also be needed in view of new knowledge about the place, new technologies or awareness about new threats. However, it is important to keep in mind that changing indicators too often will make it difficult to obtain data tracking trends over time.

Monitoring, Periodic Reporting and Reactive Monitoring - What are the differences?

For the purposes of this manual, regular and continuous monitoring to assess the ‘health’ of the attributes and other aspects of a heritage place, and inform day to day management, constitutes an essential management process, which must be undertaken systematically and in the long-term at all heritage places. For World Heritage All inherited assets which people value for reasons beyond mere utility.

Reactive Monitoring is more of an ad hoc process that is applied only to World Heritage All inherited assets which people value for reasons beyond mere utility.

It encompasses built, terrestrial, freshwater and marine environments, landscapes and seascapes, biodiversity, geodiversity, collections, cultural practices, knowledge, living experiences, etc.   properties considered under threat and which demand urgent attention by the international community.

It encompasses built, terrestrial, freshwater and marine environments, landscapes and seascapes, biodiversity, geodiversity, collections, cultural practices, knowledge, living experiences, etc.   Committee and it is conceived to be applied for limited periods of time, until the situation improves. Therefore, Reactive Monitoring is fundamentally different and does not replace the need for the systematic monitoring of the heritage place, which aims at generating insights about the health of the attributes and other aspects including informing everyday management.

As mentioned previously, effective monitoring processes at the property level will help with Periodic Reporting and Reactive Monitoring. Therefore, they should be seen as complementary processes but operating at different scales and serving different purposes. A well-designed monitoring programme should also, in many cases, help avoid Reactive Monitoring processes by alerting managers to problems at an early stage.

Box 5.3 Periodic Reporting

Periodic Reporting is one of the two types of reporting envisaged in 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.

concerning common challenges in implementing the Convention. It is an important process for the effective long-term conservation of inscribed properties while also strengthening the credibility of the implementation of the Convention. Periodic Reporting is a valuable tool for national authorities and managers too because it provides a periodic review of the effectiveness of the management systems put in place to protect World Heritage properties within a country.

Depending on their nature, management issues identified through this process may need to be addressed at the national or subnational level or, if site-specific, at the property level. While an analysis and assessment of the outcomes of the Period Reporting exercise is carried out by the World Heritage Centre The UNESCO World Heritage Centre is a technical administrative body within UNESCO, established in 1992 and appointed by the Director-General of UNESCO. It acts as the Secretariat of 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.

for each Region and presented to the World Heritage Committee, an appraisal at the national level of the results of the exercise is highly beneficial to address problems or challenges at the appropriate level and to improve overall the implementation of the provisions of the Convention.

Periodic Reporting is based on a questionnaire structured into two sections: Section I refers to the legislative and administrative provisions which the State Party has adopted and other actions which it has taken for the application of the Convention, together with details of the experience acquired in this field. This particularly concerns the general obligations defined in specific articles of the Convention. The compilation of this part of the Questionnaire falls under the relevant Focal Point’s responsibility. Section II refers to the state of conservation of specific World Heritage properties located on the territory of the State Party concerned. This Section should be completed for each 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.

and falls under the relevant managers’ responsibility. The questionnaire is accessible online for Focal Points and World Heritage appointed managers.

Over time, successive reports will build up a valuable record of the progress in implementing the Convention at the national level and in managing the properties.

is an essential part of its management system. Integrating Periodic Reporting into it helps streamline these different monitoring processes. At the property level, carrying out Periodic Reporting also offers the opportunity to reappraise management effectiveness more comprehensively and set the grounds for a review and, if needed, revision of governance arrangements, legislation, and planning mechanisms. As the Periodic Reporting process requires the commitment of managers and focal points to provide the information and go through the analysis, this could be considered in management plans as part of the programme of actions with the allocation of adequate resources.

The timing for each round of reporting is agreed upon by the World Heritage Committee, and States Parties The countries which have adhered to the Convention Concerning the Protection of the World Cultural and Natural Heritage ( 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.

report region by region in the following order:

  • Arab States
  • Africa
  • Asia and the Pacific
  • Latin America and the Caribbean
  • Europe and North America

After the full cycle of reporting, the regions are assessed again in the same order (OG paragraphs 199-207). A period for reflection and evaluation is installed after each cycle. This pause allows the Periodic Reporting mechanism to be assessed and revised as appropriate before a new cycle is initiated. Periodic Reports are submitted to the UNESCO General Conference through the World Heritage Committee.

Such updated information is submitted to the World Heritage Committee through the World Heritage Centre The UNESCO World Heritage Centre is a technical administrative body within UNESCO, established in 1992 and appointed by the Director-General of UNESCO. It acts as the Secretariat of 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.

Note that both the reports that are submitted by the State Party in response to requests made by the World Heritage Committee, and the reports that are prepared by the World Heritage Centre The UNESCO World Heritage Centre is a technical administrative body within UNESCO, established in 1992 and appointed by the Director-General of UNESCO. It acts as the Secretariat of 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.

and the Advisories to inform the Committee, are called State of Conservation reports (SOC reports). To avoid confusion, the report provided by the State Party is often called the ‘State Party SOC report’ to distinguish it from the ‘SOC report’ submitted to the World Heritage Committee. It is essential that both the national and the local management authorities act upon World Heritage Committee decisions concerning the state of conservation of a property and that all relevant actors cooperate in implementing these decisions. The World Heritage Committee’s decisions may require revisiting elements of the management system, of the management plan, or actions that are ongoing and see whether they can comply with the World Heritage Committee’s recommendations or if there is the need to adopt additional management measures to address them. This may have consequences for established management mechanisms, planned objectives, actions and resources, which may then have to be reassessed. Ways must then be found to address the concerns of the World Heritage Committee and report to them within one or two years and then regularly, until such time that the World Heritage Committee is satisfied with the outcome.

The World Heritage Committee may request that a Reactive Monitoring or an advisory mission to be carried out to investigate the circumstances of the threats, and to gather updated information on the state of conservation of the property, especially if there has been little recent information about it.

The mission will examine whether there is any indication of threats or, conversely, significant improvements in the conservation of the property since the last report to the World Heritage Committee. It will also examine whether there has been any follow-up to previous decisions of the World Heritage Committee on the state of conservation of the property and will provide information on any potential or ascertained threat or damage to or loss of OUV, including integrity and authenticity (OG paragraph 173).

The outcomes of the mission feed into the State of Conservation report prepared by the World Heritage Centre The UNESCO World Heritage Centre is a technical administrative body within UNESCO, established in 1992 and appointed by the Director-General of UNESCO.

REFLECTION QUESTIONS
  • Does the heritage place have a clearly defined monitoring programme in place?
  • What has been the basis for developing indicators to monitor the condition of the attributes at your 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.
    or other heritage place?
  • Do existing indicators cover the attributes that provide a good understanding of whether or not the OUV of the property is being maintained? Do they relate to tangible as well as intangible attributes?
  • Where possible, have thresholds been identified?
  • Are the indicators sufficient to enable an assessment of the overall condition of the property or place?
  • Are the necessary capacities to implement an effective monitoring programme available at the heritage place?
  • If not, are there opportunities to develop collaboration or partnerships, for example with universities, to ensure effective monitoring programmes are in place for the heritage place?
