Africa-Press<\/a> – Niger<\/a>. <\/strong><\/span>248 milliards $. C\u2019est le montant astronomique, repr\u00e9sentant 16 fois le PIB du pays que les esp\u00e8ces exotiques envahissantes feraient perdre au Niger chaque ann\u00e9e. L\u2019information a \u00e9t\u00e9 rendue publique dans un r\u00e9cent rapport du Centre International pour l\u2019Agriculture et la Bioscience (CABI Agriculture and Bioscience) dans un contexte o\u00f9 des millions de personnes sont menac\u00e9s d\u2019ins\u00e9curit\u00e9 alimentaire au Niger et dans le Sahel. L’\u00e9tude repose sur des donn\u00e9es de 2019.<\/p>\n

\u00ab\u2009Le co\u00fbt \u00e9lev\u00e9 nous a surpris. Notre \u00e9tude d\u00e9montre qu\u2019il est urgent de prendre des mesures pour att\u00e9nuer les impacts actuels des esp\u00e8ces exotiques envahissantes et emp\u00eacher la propagation de nouvelles esp\u00e8ces exotiques \u00e0 travers l\u2019Afrique.\u2009\u00bb, a d\u00e9clar\u00e9 Ren\u00e9 Eschen, un chercheur du CABI.<\/p>\n

Les esp\u00e8ces exotiques envahissantes sont souvent introduites de fa\u00e7on intentionnelle ou par accident, dans le cadre d\u2019efforts de lutte contre les parasites qui tournent mal. Elles arrivent ainsi \u00e0 prosp\u00e9rer en absence de leurs pr\u00e9dateurs naturels et causent des dommages \u00e9cologiques et \u00e9conomiques aux cultures locales. L\u2019\u00e9tude du CABI indique ainsi que les c\u00e9r\u00e9ales, les tubercules, les tomates et d\u2019autres l\u00e9gumes ont \u00e9t\u00e9 les plus durement touch\u00e9s par ces esp\u00e8ces \u00e9trang\u00e8res.<\/p>\n

D\u2019apr\u00e8s les informations, le Niger n\u2019est pas le seul pays touch\u00e9 par cette situation. Le Nigeria perdrait environ 1000 milliards $ par an, selon les chercheurs. Les pertes de la R\u00e9publique d\u00e9mocratique du Congo (RDC) sont quant \u00e0 elles estim\u00e9es \u00e0 317 milliards $ et celles de l\u2019Afrique du Sud \u00e0 229 milliards $.<\/p>\n

Au total, le continent africain perdrait chaque ann\u00e9e 3 500 milliards $ du fait de ces esp\u00e8ces alors que son PIB se situait \u00e0 environ 2 000 milliards en 2019.<\/p>\n

Pour endiguer les pertes, le centre de recherche a recommand\u00e9 aux gouvernements d\u2019adopter une approche proactive. \u00ab\u2009Les investissements visant \u00e0 trouver des moyens plus efficaces de lutter contre les esp\u00e8ces- y compris la pr\u00e9vention de l\u2019\u00e9tablissement de nouvelles esp\u00e8ces et de la propagation des esp\u00e8ces \u00e9tablies – ainsi que la gestion rentable des esp\u00e8ces r\u00e9pandues en utilisant, par exemple, la lutte biologique, pourraient r\u00e9duire les co\u00fbts de gestion et les pertes de rendement\u2009\u00bb, a d\u00e9clar\u00e9 \u00e0 cet effet, Ren\u00e9 Eschen.<\/p>\n

Notons que l\u2019actuel pr\u00e9sident Mohamed Bazoum a fait de la diversification de l\u2019\u00e9conomie \u00e0 travers la relance de l\u2019agriculture l\u2019un des axes principaux du plan de renaissances Acte 3.<\/p>\n","protected":false},"excerpt":{"rendered":"
