Discussing Unesco’s definition of “natural heritage”

Natural heritage is part of world heritage according to UNESCO. The most common definition of what natural heritage is has been given by this institution in 1972:

Natural heritage refers to natural features, geological and physiographical formations and delineated areas that constitute the habitat of threatened species of animals and plants and natural sites of value from the point of view of science, conservation or natural beauty. It includes private and publically protected natural areas, zoos, aquaria and botanical gardens, natural habitat, marine ecosystems, sanctuaries, reservoirs etc.

Here are some examples of natural heritage sites registered on the world heritage list :

UNESCO’s definition has been created for “sites“: large areas that should be preserved, not individual elements. This definition is very broad, and not limited. It includes everything natural, organic and mineral, whether or not it has been modified by human presence (like botanical gardens). The criteria, however, are way more restrictive.

Here are the defining criteria used to qualify world natural heritage sites:

(vii) to contain superlative natural phenomena or areas of exceptional natural beauty and aesthetic importance;

(viii) to be outstanding examples representing major stages of earth’s history, including the record of life, significant on-going geological processes in the development of landforms, or significant geomorphic or physiographic features;

(ix) to be outstanding examples representing significant on-going ecological and biological processes in the evolution and development of terrestrial, fresh water, coastal and marine ecosystems and communities of plants and animals;

(x) to contain the most important and significant natural habitats for in-situ conservation of biological diversity, including those containing threatened species of outstanding universal value from the point of view of science or conservation.

The Criteria for Selection, UNESCO

This definition seems to focus on exceptional features firstly, which are not necessarily the most necessary in terms of nature preservation in general. The interest in aesthetics seems to be very anthropocentric as well.

UNESCO is obviously managed by humans, so it seems impossible to withdraw all anthropocentrism from this selection. However, we know what natural habitats are important for other living beings. As such, we could choose less anthropocentric criteria. We also know that some of our activity changes Earth’s geological features (see Hydraulic fracturing volume is associated with induced earthquake productivity in the Duvernay play), but the ground or water, in general, are not listed here.

Taking care of nature, exceptional or not, seems generally beneficial to humankind, but not necessarily in the short term, as illustrated by the preservation of predators like wolves (see for instance: Where can wolves live and how can we live with them?).

One of UNESCO’s missions is to choose which sites will be protected, so they need to classify, evaluate and hierarchize. There is a question of scale here: this global systematic approach might be the most appropriate for them, but it might not be the only interesting one, especially when we discuss video games that could change players’ individual behaviours.

Conservation and education about nature can indeed happen at a small scale and for natural elements that are neither big, rare or awe-inspiring. The self-propagating plants/weeds, pests and “invasive animal species” have for instance been in researchers’ interest recently for their interest in biodiversity (see for instance Sales bêtes ! Mauvaises herbes ! “Nuisibles” une notion en débat).

It is interesting to note that weeds are generally called “bad herbs”: “mauvaises herbes” in French. Although it is interesting to note that the term “adventice” is gaining popularity at the moment. There is no proper translation in English for “adventice”. It means roughly: plants that grow first on the ground, by themselves, and which are necessary for bigger and most “precious” plants to appear.

From the point of view of UNESCO, it would be meaningless to classify every natural element as natural heritage, as they don’t have the possibility to preserve them all. But for video games creators and scholars interested in the digital nature, shouldn’t it be the case? Or should we, also, prioritize? If so, should we follow the same criteria?
