The world is there to protect. UNESCO will do its utmost to realize this. However, this is not always easy. Many factors make heritage at risk. Factors caused by human beings and also nature. What factors play a role and how does UNESCO on this hazard?

..:: World Heritage in Danger: The factors

World Heritage sites are threatened by both natural disasters and actions arising from human activities. War, for example, or pollution, urbanization and tourism. It has everything to do with that no effect on the value of heritage.

..:: UNESCO

As a result, the World Heritage Committee shall decide on the endangered list of endangered heritage sites. This can be achieved by the heritage area and to analyze problems and to explore the heritage which is assisted by the Committee to deal with problems. If all the problem factors and threats are removed, and the value of heritage has been restored and made safe, then the heritage of the list are removed.

..:: Example:

An example of heritage is in danger of Atsinanana the rainforest region. This region was on the list of endangered heritage in 2010. The area consists of 6 national parks in the eastern part of Madagascar. Madagascar 60 million years ago, was detached from the mainland. In all those years, the flora and fauna to develop and evolve in isolation. The forests are now very important for the maintenance of unique ecological processes that will be needed for the conservation and survival of the unique biodiversity of the island of Madagascar. Furthermore, the forests the home of many endangered species including primates and lemurs. This area by UNESCO on the list because they believe that this area several times over the years been a refuge for animals in times of climate change and this area will also be at the next climate change. Furthermore, as in any rain forest, deforestation is a major threat. In eastern Madagascar is only about 8.5% of the original forest. It is one of the most unique and valuable areas in the world so it is absolutely necessary protection.

..:: Climate change

In the last 20 years, climate change is becoming a larger and more discussed problem. Climate change is one of the biggest challenges in the 21st century.

..:: UNESCO

Because climate change is a threat to the world cultural and natural heritage, UNESCO has constantly analyzing and investigating potential threats and developments. UNESCO sites and then analyze to see how climate change will have on the heritage or to what extent this has already happened. UNESCO wants to prevent damage and reduce it if necessary. UNESCO has launched many projects and coordinates many initiatives related klimaatvernadering.

..:: Example:

An example of heritage that has been affected by climate change and also in the future is influenced Venice and the lagoon, situated in northern Italy on the Adriatic Sea. Venice is an architectural masterpiece with extraordinary art that must be protected and preserved. By the subsidence of the land, the city has sunk 10 cm. This process was further strengthened by the industrial water from deep aquifers began to pump. Now the city drops even faster with 10-13 cm per year. Pumping has been stopped since the year 1970, but damage has already been done. On the other hand, the sea water on the rise due to climate change. Venice is therefore more risk to flooding and also to sink into the ground. The government is now a resistance to the building which is closed when the water level rises too high. However, comprehensive and reliable preservation of Venice will always remain a challenge. Experts are still unsure about the fate Venice will take in the future.
