“La Coordinadora” protests against light pollution of the environment of the “Parc Natural del Turia
miércoles 7 de noviembre de 2007
La Coordinadora denuncia la contaminación lumínica del entorno del Parc Natural del Túria
Centenares de farolas públicas y multitud de alumbrados
exteriores privados proliferan por las urbanizaciones La
Vallesa, Monte Canyada "violando" y contaminando el cielo
nocturno.
Urge una ordenanza municipal para detener la contaminación
lumínica, el derroche energético y el Cambio Climático, así
como el impacto contra las personas, la fauna y la flora.
La Coordinadora en Defensa de los Bosques del Túria
reivindica la Defensa de la Calidad del Cielo Nocturno y el
Derecho a Observar las Estrellas en el Parc Natural del Túria y
las poblaciones de su entorno.
RECOMMENDATIONS OF THE VALENCIA UNIVERSITY REPORT
PRESENTED TO THE GOVERNING PARK BOARD:
i)
Removing unshielded ball-type luminaires.
ii)
Power reduction and reorientation of the luminaries.
iii)
Place the light as low as possible and directed downward.
iv)
Use lights with optics that provides light cones as sharp as possible.
v)
Use more efficient and less polluting lamps:
Red light better than white or blue.
vi)
Use vegetable screens.
vii)
Pay attention to areas bordering urban areas where there may be
excess lighting, and special attention to sports facilities located near the
Park, and
viii)
Implement the regulation of energy efficiency in outdoor lighting
installations of Royal Decree 1890/2008 of 14 November.
The University warns about light pollution in the Turia Natural Park

CONCLUSIONS
1. No awareness of government and the majority of the population.
2. More important light pollution sources:
- Great infrastructures :
- Airport
- Industrial Areas
- Electric Power Plants
- Water Distribution Plants
- Water Treatment Plants
- Roads, Traffic circles
- Commercial Areas
- Municipal and private sports centers
- Schools
- Residential Areas
- Monument Lighting
FUTURE ACTIONS
Disseminating the results of this study :
- Press Releases.
- Seminars in Schools.
- Talks to neighborhood, environmental and cultural associations.
Presentation of motions in the municipalities.
Continuation of the study.
Apply for the Valencian Light Pollution Law.
STOP THE LIGHTS. YOU HAVE STOLEN US THE NIGHT
IT IS TIME TO SWITCH OFF THE LIGHT
