Background on the Initiative

The quality of the night sky has been a concern for a number of years. Growth of light pollution globally has strengthened the worldwide movement to protect natural dark skies. In 2007 a consortium of international organisations (United Nations Educational, Scientific and Cultural Organization – UNESCO, World Tourism Organization – UNWTO, International Astronomical Union – IAU and others), Secretariats of conventions relevant to biodiversity (Convention on the Biological Diversity, Convention on Migratory Species, Ramsar Convention) and representatives of the academic community met in La Palma, Canary Islands, Spain, at the International Conference in Defense of the Quality of Night Sky. The resulting Declaration in Defence of the Night Sky and the Right to Starlight is a linchpin document for protection of the natural sky. It recognises the importance and multi-faced value of the night sky and provides a plan for action.

The Initiative for an International Association of Dark-sky Parks aims to implement the principles of the Declaration, in particular through its 10th principle:

“[a]ll those protected areas which combine exceptional landscape and natural values relying on the quality of their night sky, are called to include protection of clear night skies as a key factor strengthening their mission in conserving nature.”

The Initiative builds a strong network of people who will in their respective countries work to reduce light pollution. Their role may be in establishing effective regulatory framework for protection from growing light pollution and its reduction, in providing scientific input to the efforts and raising awareness. It brings together all those that have knowledge, experience, responsibilities or motivation to contribute to a positive change.


The 2010 Symposium

The aim of the 2010 Symposium on Dark-sky Parks is to establish an effective long-term framework for reducing light pollution internationally. It will do so by bringing together key players that will determine with the appropriate course of action. The Symposium not only provides a setting for individuals to present their knowledge or attend presentations by leading experts in the light-pollution field. It also creates an opportunity for networking, collaboration, sharing of information and the building of trust relationships. Dark-sky movement continues to enjoy a steady increase in membership internationally and is represented by individuals from tourism, research, educational, management, government, student and other communities.

Symposium participants are site managers, representatives of international and national (non-governmental) organisations, experts in biology, (eco)tourism, natural and cultural heritage, lighting industry, etc.

The symposium is a five-day event, comprising of quality lectures, field-trips and night observations.

The symposium language is English.

Cultural and natural heritage – hindering enjoyment of nature

–    Fully shielded lighting both in cities and rural areas. Redirecting light down only to where it is needed reduces the unnecessary spill of light and the required lamp wattage.

–    Use of low- or high-pressure sodium lighting with the orange component instead of the mercury lamps or metal halide discharge lamps with the enhanced blue / bluish component. The enhanced blue part of the spectrum is visible by more animal species and humans.

–    Reducing the levels of illumination of lights at night or turning them off when these are not needed (dimming).

–    Limitation on illumination of surfaces (outdoor advertising signs, billboards, facades, decorative lighting etc.).

–    Sensible spatial planning. Public lighting is not necessarily needed on each parking lot, in rural areas or on roads intended only for use of vehicles.

–    Laws, not voluntary reductions are needed. Self-regulation is likely to not be effective against the comercial interests, capital or ignorance.


Problems of light pollution:



Cultural and natural heritage



Light pollution as a threat to biodiversity

A biological rhytm of day and night is natural to several species, habitats and ecosystems and indispensable for a healthy funcitoning of the biosphere. Artificial light affects the growth of plants and their resistance to infestations and disease, and influences the growth, feeding, reproduction and migration patterns of a number of animals.

Although more ecological impacts of light pollution are expected to be known as the research in the field progresses, sufficient evidence exists about the importance of darkness for a number of animal and plant species. It is our responsibility to protect them, especially if the solutions are simple.


Light pollution as a threat to human health

The biological rhytm of day-light and darkness is natural also to humans and thus vital to our health. By suppressing melatonin production and interfering with the circadian rhythms, intrusive street lighting entering into bedrooms at night may lead to sleep deprivation, depression and impaired thinking. Research has shown that long-lasting increase of systolic blood pressure could be linked with an increase of risk of cardiovascular diseases like stroke and myocardial infarction. High night-light intensity has also been associated with the higher incidence of breast cancer, pointing to the possibility that exposure to light at night may be the most powerful factor in breast cancer besides genetic defects.

Although further research is needed health effects demonstrated so far are alarming enough to urge a response.


Light pollution hinders enjoyment of (nocturnal) nature

Artificial skyglow is becoming an ever more serious hindrance to enjoyment of the starlight and astronomical research. Professional astronomy as it has been developing over the past centuries is a key to understanding our world. Not only scientists, each individual has a right to an unpolluted night sky that has a aesthetic, cultural and spiritual value.

These and many more values of pristine night sky have been recognised in the Declaration in Defense of the Night Sky and the Right to Starlight, adopted in La Palma in 2007. Among others, protected areas are “called to include the protection of clear night skies as a key factor strenghtening their mission.”

Light pollution is a waste of energy and considerably contributes to climate change

Unshielded lighting emits up to 50% of light in the sky. Production of this unnecessary energy has considerable economic and environmental impacts. These are greatly at odds with the efforts to reduce energy inefficiency and greenhouse gas emissions.

Avoiding light pollution is not only an ecologically but also economically viable solution. Finally, only ecological outdoor lighting is consisent with the principles of sustainable development.
