Le m\u00e9decin-explorateur fran\u00e7ais Jean-Louis \u00c9tienne, premier \u00e0 avoir atteint le p\u00f4le nord g\u00e9ographique en solitaire en 1986, lance une nouvelle exp\u00e9dition scientifique en Antarctique pour alimenter les connaissances sur ce continent m\u00e9connu et gravement menac\u00e9 par les activit\u00e9s humaines.<\/p>\n

\u00ab\u00a0Les p\u00f4les sont le t\u00e9moin du changement climatique\u00a0\u00bb et les aires marines prot\u00e9g\u00e9es (AMP), dont il d\u00e9fend la cr\u00e9ation en Antarctique, \u00ab\u00a0on en a besoin, sinon on va vers une disparition progressive\u00a0\u00bb de ces \u00e9cosyst\u00e8mes \u00ab\u00a0pr\u00e9cieux pour la plan\u00e8te\u00a0\u00bb, a d\u00e9clar\u00e9 jeudi M. \u00c9tienne lors d’une conf\u00e9rence de presse.<\/p>\n

L’exp\u00e9dition \u00ab\u00a0Pers\u00e9v\u00e9rance en Antarctique\u00a0\u00bb partira le 20 janvier de Christchurch (Nouvelle Z\u00e9lande), \u00e0 destination de la Mer de Ross puis de la mer Dumont d’Urville, au sud de l’Antarctique. Elle durera jusqu’au 15 mars.<\/p>\n

A bord du navire, une s\u00e9rie d’appareils de mesures perfectionn\u00e9s pour \u00e9tudier les donn\u00e9es m\u00e9t\u00e9orologiques, dresser un panorama de la faune marine, \u00e9tudier les polluants atmosph\u00e9riques ou encore l’\u00e9tat du phytoplancton ou la hauteur des vagues.<\/p>\n

\u00ab\u00a0Le continent Antarctique c’est 28 fois la surface de la France\u00a0\u00bb et \u00ab\u00a0c’est 70 \u00e0 80% de la glace\u00a0<\/span>de la plan\u00e8te\u00a0\u00bb, souligne Jean-Louis Etienne.<\/p>\n

L’explorateur de 79 ans avait d\u00e9j\u00e0 effectu\u00e9 une travers\u00e9e int\u00e9grale de l’Antarctique en 1989\/1990. \u00ab\u00a0On ne pourrait plus refaire la m\u00eame exp\u00e9dition aujourd’hui\u00a0\u00bb car une partie de l’Antarctique a d\u00e9j\u00e0 disparu sous l’effet du r\u00e9chauffement de la temp\u00e9rature \u00e0 la surface des mers et de l’\u00e9l\u00e9vation du niveau des oc\u00e9ans, a d\u00e9plor\u00e9 M. \u00c9tienne.<\/p>\n

L’autre menace qui p\u00e8se sur la biodiversit\u00e9 du continent est la p\u00eache industrielle, et \u00ab\u00a0c’est la raison pour laquelle il faut de nouvelles AMP sur ce secteur car de plus en plus de bateaux usines viennent y p\u00eacher\u00a0\u00bb, notamment le krill, petit crustac\u00e9 qui est \u00ab\u00a0la cl\u00e9 de voute\u00a0\u00bb du r\u00e9seau alimentaire des esp\u00e8ces de la r\u00e9gion, souligne l’explorateur.<\/p>\n

L’exp\u00e9dition Pers\u00e9v\u00e9rance aura aussi pour mission d’apporter une meilleure compr\u00e9hension de l’impact de l’aire marine prot\u00e9g\u00e9e de la mer de Ross, dix ans apr\u00e8s sa mise en place, alors qu’un nouveau projet d’aire est d\u00e9fendue par la France et l’Australie, avec le soutien de l’Union europ\u00e9enne, dans l’Antarctique Est.<\/p>\n

Quatre autres projets d’aires sont actuellement en n\u00e9gociation au sein de la Convention pour la Conservation de la Faune et de la Flore Marines de l’Antarctique (CCAMLR).<\/p>\n

La strat\u00e9gie nationale fran\u00e7aise pour les aires prot\u00e9g\u00e9es pr\u00e9voit d’ici 2030 que 30% du territoire (terrestre et marin) soit couvert par des espaces prot\u00e9g\u00e9s, dont 10% en protection forte.<\/p>\n
