\u00a0\u00a0\u00a0\u00a0 Dans le cadre de la collaboration entre l\u2019Agence Spatiale Alg\u00e9rienne (ASAL) et l\u2019Institut National de la Protection des V\u00e9g\u00e9taux (INPV) dans le domaine de la lutte contre le criquet p\u00e8lerin s\u2019inscrivant au titre de la campagne printani\u00e8re 2019 couvrant la r\u00e9gion centrale du Sahara Alg\u00e9rien.<\/p>\n

\u00a0\u00a0\u00a0\u00a0 Pour cela, l\u2019ASAL a exploit\u00e9 et analys\u00e9 les images du satellite alg\u00e9rien Alsat-1B, couvrant la r\u00e9gion de Tindouf (Sud-Ouest du territoire national) du mois de f\u00e9vrier 2019 et ce, afin d\u2019identifier les zones \u00e9cologiquement potentiellement favorables \u00e0 la reproduction ducriquet p\u00e8lerin.<\/p>\n

\u00a0\u00a0\u00a0\u00a0 A ce titre, deux (02) images satellitaires Alsat-1B prises en f\u00e9vrier 2019 couvrant cette r\u00e9gion (figure 1), sur une superficie de\u00a053 318 Km2\u00a0<\/strong>ont \u00e9t\u00e9 exploit\u00e9es pour \u00e9valuer les conditions \u00e9cologiques.<\/p>\n

\u00a0\u00a0\u00a0 Les traitements r\u00e9alis\u00e9s ont permis d\u2019\u00e9laborer des spatiocartes destin\u00e9es \u00e0 \u00e9valuer les conditions \u00e9cologiques des biotopes acridiens, constituant ainsi un support d\u2019aide \u00e0 la d\u00e9cision lors de la p\u00e9riode de pr\u00e9vision et de pr\u00e9paration des missions de prospection de l\u2019INPV (voir figures 2, 3 &4).<\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0 Enfin, l\u2019analyse des conditions \u00e9cologiques dans la r\u00e9gion de Tindouf \u00e0 partir des images Alsat-1B, met en relief au niveau de Hassi Mounir et Oum El Assel, une v\u00e9g\u00e9tation \u00e9parse\u00a0avec une bonne activit\u00e9 chlorophyllienne favorables au d\u00e9veloppement du criquet p\u00e8lerin. Cette activit\u00e9 chlorophyllienne est localis\u00e9e principalement au niveau des lits d\u2019oueds et des d\u00e9pressions endor\u00e9iques.<\/p>\n
