The diversity of the ever-changing dune formations, sculpted by pronounced daily and seasonal changes in dominant wind directions is also exceptional at a global scale within such a relatively small area.Ĭriterion (ix): The property is an exceptional example of ongoing ecological process in a coastal fog desert where plant and animal communities are continuously adapting to life in a hyper arid environment. Although the nominated area encompasses only the Aeolian elements of this ongoing geological process the other elements of the ‘conveyor system’ are assured. The diversity of dune formations, their ever-changing form and the range of colour and texture create landscapes of outstanding natural beauty.Ĭriterion (viii): The property represents an exceptional example of ongoing geological processes involving the formation of the world’s only extensive dune system in a coastal fog desert through transport of material over thousands of kilometres by river, ocean current and wind. The age, extent and height of the dunes are outstanding and the property also exhibits a range of features that give it exceptional aesthetic qualities.
Most dune fields elsewhere in the world are derived from bedrock eroded in situ. This alone makes it exceptional at a global scale, but it also represents a superlative natural phenomenon on account of the three-part ‘conveyor system’ which has produced the massive dune field from material transported over thousands of kilometres from the interior of the African continent by river erosion, ocean currents and wind. The large number of endemic plants and animals are globally-important examples of evolution and the resilience of life in extreme environments.Ĭriterion (vii):The property is the world’s only coastal desert that includes extensive dune fields influenced by fog. Life in the fog-bathed coastal dunes of the Namib Sand Sea is characterised by very rare behavioural, morphological and physiological adaptations that have evolved throughout its specialist communities. It is a place of outstanding natural beauty where atmospheric conditions provide exceptional visibility of landscape features by day and the dazzling southern hemisphere sky at night. The sand sea includes most known types of dunes together with associated landforms such as inselbergs, pediplains, and playas, formed through aeolian depositional processes. It is an outstanding example of the scenic, geomorphological, ecological and evolutionary consequences of wind-driven processes interacting with geology and biology. The Namib Sand Sea is a unique coastal fog desert encompassing a diverse array of large, shifting dunes. It covers an area of 3,077,700 hectares, with an additional 899,500 hectares designated as a buffer zone. The Namib Sand Sea lies along the arid African coast of the South Atlantic lying wholly within Namibia’s Namib-Naukluft Park.

Le brouillard est ici la principale source d’eau, contribuant à un environnement, unique à une telle échelle, où invertébrés, reptiles et mammifères endémiques s’adaptent à une grande variété de micro-habitats et de niches écologiques toujours changeantes.ĭescription is available under license CC-BY-SA IGO 3.0 Le site comprend également des plaines de gravier, des cuvettes côtières, des collines rocheuses, des inselbergs à l’intérieur de l’erg, un lagon côtier, des cours d’eau éphémères, le tout formant un paysage d’une beauté exceptionnelle. L’endroit est exceptionnel car les dunes sont constituées de matériaux venus de loin, transportés depuis l’intérieur de l’Afrique australe par les cours d’eau, les courants océaniques et le vent.

L’Erg est composé de deux systèmes dunaires, un système ancien semi-consolidé sur lequel se superpose un système plus jeune et plus actif.
est le seul désert côtier où l’on trouve de vastes champs de dunes de sable sous l’influence du brouillard. Le site qui s’étend sur plus de trois millions d’ha.
