Africa-Press – Madagascar. <\/strong><\/span>En Afrique de l\u2019Ouest, l\u2019agriculture est encore une fois menace\u0301e. Contre les vagues d\u2019insectes nuisibles, les experts locaux pre\u0301conisent une pre\u0301vention accrue.<\/p>\n

L\u2019Organisation des Nations Unies pour l\u2019alimentation et l\u2019agriculture (FAO) alerte sur le retour du criquet pe\u0300lerin, en provenance du Sahel. Au me\u0302me titre que la chenille le\u0301gionnaire, ce nuisible envahit et de\u0301truit les re\u0301coltes a\u0300 l\u2019Ouest du continent.<\/p>\n

Au Tchad, cela vient s\u2019ajouter aux diffe\u0301rentes se\u0301cheresses de cet e\u0301te\u0301 et empire la situation pour une population de\u0301ja\u0300 vulne\u0301rable. Cette nuisance coupe les cultivateurs de tout revenu, notamment dans le de\u0301partement de Kanem.<\/p>\n

Selon Dominique Burgeon, directeur des urgences de la FAO, un essaim de criquets se de\u0301veloppe tre\u0300s rapidement : \u00ab Le nombre est d\u2019abord multiplie\u0301 par 20, puis par 400 trois mois plus tard, puis par 8 000 au bout de six mois et ainsi de suite. \u00bb Il rappelle que la population de cette espe\u0300ce ende\u0301mique peut e\u0302tre contro\u0302le\u0301e, si elle est repe\u0301re\u0301e to\u0302t.<\/p>\n

Pluto\u0302t que d\u2019intervenir par des moyens ae\u0301riens avec des pesticides, il est alors possible d\u2019intervenir au sol, a\u0300 moindre cou\u0302t et de fac\u0327on plus efficace. Faire de la pre\u0301vention une priorite\u0301 commune.<\/p>\n

\u00ab La lutte contre les criquets ne peut pas se faire a\u0300 l\u2019e\u0301chelle d\u2019un seul village. Cela doit se faire en collaboration avec des organismes comme l\u2019ANADER (Agence Nationale d\u2019Appui du De\u0301veloppement Rural), la FAO et les autres ONG. \u00bb En fin septembre, l\u2019inge\u0301nieure agronome tchadienne Achta Youssouf Nahar tirait la sonnette d\u2019alarme.<\/p>\n

Si continuer d\u2019alerter la population sur l\u2019arrive\u0301e des insectes sur place, et les aider apre\u0300s coup reste important, prendre des mesures pre\u0301ventives est fondamental : \u00ab Il faut identifier ces criquets bien avant, leurs positionnements exacts. Puis, essayer de les de\u0301truire a\u0300 leur e\u0301tat de larves, pour qu\u2019ils ne puissent pas se de\u0301velopper apre\u0300s \u00bb, insiste l\u2019inge\u0301nieure.<\/p>\n

Les essaims sur le territoire tchadien devraient se diriger vers l\u2019Alge\u0301rie, le Maroc, la Mauritanie et la Libye.<\/p>\n
