Dans le cadre de la campagne estivale de lutte contre le criquet p\u00e8lerin, visant la localisation des zones \u00e9cologiquement favorables, susceptibles d\u2019abriter la reproduction acridienne en cette p\u00e9riode, l\u2019Agence Spatiale Alg\u00e9rienne a analys\u00e9 les images satellitaires \u00e0 moyenne r\u00e9solution\u00a0, du mois d\u2019ao\u00fbt 2012, couvrant la r\u00e9gion de l\u2019extr\u00eame Sud Alg\u00e9rien, le Nord du Mali et le Nord du Niger et ce, sur une superficie de\u00a0\u00a0 681 508 km2 <\/strong>[figure 1].<\/p>\n

L\u2019analyse des conditions \u00e9cologiques du criquet p\u00e8lerin \u00e0 partir de ces images a permis de localiser les zones susceptibles d\u2019abriter le criquet p\u00e8lerin et sa reproduction, notamment dans les r\u00e9gions du Kidal <\/strong>et Gao<\/strong> au Nord du Mali et au Sud et \u00e0 l\u2019Est d\u2019Arlit<\/strong> (Nord du Niger).<\/p>\n

En effet, dans les r\u00e9gions du Kidal<\/strong> (Mali) [Figure 2] et Arlit<\/strong> (Niger) [figure 3], on note la pr\u00e9sence d\u2019un couvert v\u00e9g\u00e9tal dense \u00e0 tr\u00e8s forte activit\u00e9 chlorophyllienne, localis\u00e9 principalement dans les lits d\u2019oueds.<\/p>\n

Enfin, toutes les zones identifi\u00e9es pr\u00e9sentent des conditions \u00e9cologiques tr\u00e8s favorables \u00e0 la reproduction du criquet p\u00e8lerin dans la r\u00e9gion d\u2019\u00e9tude.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"
