Methodologies

IUCN World Heritage Outlook 3 builds on three cycles of Conservation Outlook Assessments undertaken since 2014. It presents the main results for 2020, but also some longer-term trends based on a comparison of three data sets now available.

Of the 8,300 million tonnes of plastic produced from 1950 to 2015, only 7% has been recycled while more than half has been discarded in landfill or leaked into the environment. Companies, organisations, and governments are taking measures to tackle plastic pollution. However, there is currently no standard methodology to measure the extent of the plastic problem.

Natural World Heritage sites are internationally recognised as having the highest global nature conservation priority. As of November 2017, there are 241 natural and mixed (both cultural and natural) World Heritage sites, representing about 0.1% of the total number of protected areas globally, but yet with a total coverage of 294 million hectares, accounting for 8% of the combined surface of terrestrial and 6% of marine protected areas.

Los sitios naturales de Patrimonio Mundial se reconocen internacionalmente por representar la principal prioridad mundial para la conservación de la naturaleza. Incluyen lugares como el Serengeti, la Gran Barrera de Coral y las Islas 

Entre los años 2004 a 2007, la UICN desarrolló el proyecto “Manejo Integrado de las Cuencas Asociadas al Volcán Tacaná”, período en el que el paso del huracán Stan dejó consecuencias devastadoras.

Les sites naturels du patrimoine mondial sont internationalement reconnus comme étant en tête des priorités pour la préservation de la planète et incluent des lieux emblématiques tels que le Serengeti, la Grande Barrière et les îles Galápagos.

After a short introduction of the IUCN Commission on Ecosystem Management (CEM), the present presentation develops the application of the ecosystem approach by the military sector, in particular in relation to peace-support operations and reconstruction programmes. It describes a simple model of 4 steps. The first step deals with the physical system (“the ecosystem”), the second step with the use of the ecosystem and the third step with its management (institutions and regulations).
