Africa-Press – Senegal. <\/strong><\/span>Vers une carte comple\u0300te des fonds marins<\/b><\/p>\n

Amorce\u0301 en 2017, le projet Seabed 2030 vise a\u0300 cartographier l\u2019inte\u0301gralite\u0301 des fonds marins d\u2019ici a\u0300 2030 en compilant toutes les donne\u0301es bathyme\u0301triques disponibles. Depuis son lancement, l\u2019initiative internationale a enregistre\u0301 une augmentation de 4,34 millions de km2 de nouvelles donne\u0301es, soit 26,1 % du plancher oce\u0301anique.<\/p>\n

Dans les prochaines anne\u0301es, l\u2019exploration des abysses be\u0301ne\u0301ficiera par ailleurs de technologies innovantes, tels les robots autonomes pilote\u0301s par intelligence artificielle ou les re\u0301seaux de capteurs ca\u0302ble\u0301s et mobiles, qui permettront de mieux connai\u0302tre une biodiversite\u0301 dont plus de 90 % des espe\u0300ces seraient encore inconnues.<\/p>\n

Les promesses du microbiome oce\u0301anique<\/b><\/p>\n

L\u2019immense biodiversite\u0301 microbienne des oce\u0301ans reste largement inconnue. Gra\u0302ce au se\u0301quenc\u0327age de l\u2019ADN environnemental, on s\u2019attend a\u0300 de\u0301couvrir des milliers d\u2019espe\u0300ces dans les abysses, les sources hydrothermales ou les zones anoxiques. Une mine d\u2019or pour les biotechnologies, qu\u2019il s\u2019agisse de la mise au point de nouveaux me\u0301dicaments, de bioreme\u0301diation avec des microbes capables de de\u0301grader plastiques ou me\u0301taux lourds, ou de nouvelles voies de me\u0301tabolisation du CO2, inspiratrices de technologies de capture du carbone.<\/p>\n

Des plantes plus re\u0301sistantes gra\u0302ce a\u0300 l\u2019ADN<\/b><\/p>\n

Comment enrayer la pe\u0301nurie alimentaire mondiale? La recherche espe\u0300re trouver la re\u0301ponse en perc\u0327ant le secret de l\u2019ADN des plantes anciennes, aujourd\u2019hui disparues. En suivant l\u2019e\u0301volution des espe\u0300ces gra\u0302ce aux traces ge\u0301ne\u0301tiques laisse\u0301es dans l\u2019eau ou le sol, il serait possible de repe\u0301rer les traits qui rendaient les cultures plus re\u0301sistantes et plus abondantes. Puis de les reproduire sur les ce\u0301re\u0301ales, les fruits et les le\u0301gumes d\u2019aujourd\u2019hui, dont le rendement est plus faible.<\/p>\n

La me\u0301te\u0301o ultralocale<\/b><\/p>\n

Capteurs, radars, imagerie satellitaire: gra\u0302ce a\u0300 ces outils, la pre\u0301vision me\u0301te\u0301o s\u2019applique a\u0300 des territoires de plus en plus restreints. Cette pre\u0301cision grandissante va permettre d\u2019anticiper des e\u0301ve\u0301nements violents et tre\u0300s localise\u0301s comme les orages, qui devraient arriver plus souvent dans un climat plus chaud. Mais c\u2019est en agriculture que les attentes sont les plus fortes. La \u00ab me\u0301te\u0301o a\u0300 la parcelle \u00bb commence a\u0300 apporter la preuve qu\u2019elle peut permettre aux agriculteurs d\u2019e\u0301conomiser l\u2019eau et de mieux ge\u0301rer leurs cultures.<\/p>\n
