L’agence d’information agricole romande (AGIR) a relat\u00e9 hier l’id\u00e9e du d\u00e9put\u00e9 Vert Bernard Martin (canton de Vaud) pour lutter contre l’effet de serre. L’id\u00e9e est la suivante: \u00ab\u00a0Les terres cultiv\u00e9es repr\u00e9sentent le plus grand puits de carbone du monde, apr\u00e8s les oc\u00e9ans et avant l’atmosph\u00e8re. Pourquoi ne pas les utiliser pour lutter contre le r\u00e9chauffement climatique?\u00a0\u00bb.\u00a0 Ainsi se r\u00e9sume le \u00ab\u00a0postulat\u00a0\u00bb (cela s’appelle ainsi chez nos voisins helv\u00e8tes) de M.Martin.<\/p>\n

\"p1000197.jpg\"<\/p>\n

Pour le d\u00e9put\u00e9 Vert suisse Bernard Martin, les agriculteurs pourraient vendre des quotas de carbone… <\/em><\/p>\n

Une id\u00e9e qui a interloqu\u00e9 tout le monde, semble t-il. Sp\u00e9cialistes, agriculteurs et repr\u00e9sentants de l’Etat sont rest\u00e9s partag\u00e9s sur le sujet. La responsable du D\u00e9partement vaudois de l’\u00e9conomie a bott\u00e9 en touche, expliquant que l’Agroscope Changins-W\u00e4denswil a \u00e9t\u00e9 sollicit\u00e9 sur ce sujet, que les avis des experts ne sont pas unanimes et que le Canton ne dispose pas des comp\u00e9tences requises en la mati\u00e8re pour entreprendre l’\u00e9tude demand\u00e9e par le postulat. Par 4 voix contre 3, la commission a refus\u00e9 de faire suivre le dossier au Conseil d’Etat. Le d\u00e9put\u00e9 Martin a maintenu son postulat avec un rapport de minorit\u00e9. Il est pr\u00e9vu d’en re-discuter \u00e0 l’automne.<\/p>\n

Accro\u00eetre la part de carbone stock\u00e9 dans le sol fait partie des possibilit\u00e9s d’abaisser le taux de gaz carbonique dans l’atmosph\u00e8re. Jean-Auguste Neyroud, chercheur \u00e0 l’Agroscope de Changins, confirme ce point, selon AGIR, allant donc dans le sens de l’ \u00e9cologiste suisse. Pour arriver \u00e0 ce r\u00e9sultat, Bernard Martin propose d’augmenter le taux d’humus – la fraction la plus fine de la mati\u00e8re organique d\u00e9compos\u00e9e – dans les sols. Comment? \u00ab\u00a0Par rotation des cultures, apports de fumier, de compost, de lisier et de purin enrichis, restitution de paille, non labour, mise en prairie\u2026\u00a0\u00bb, pr\u00e9cise t-il. Il pense ainsi que la moyenne actuelle en Suisse – 60 tonnes de carbone organique par hectare – pourrait \u00eatre un peu plus que doubl\u00e9e.<\/p>\n

Mais la proposition ne s’arr\u00eate pas l\u00e0. Comme le pr\u00e9cise AGIR, elle vise \u00e9galement l’entr\u00e9e des sols enrichis en humus sur le march\u00e9 du carbone: \u00ab\u00a0Depuis la signature du Protocole de Kyoto, les entreprises (industrielles, agricoles ou autres) peuvent vendre ou acheter des quotas de carbone. Ainsi, l’agriculture aurait la possibilit\u00e9 de devenir cr\u00e9ditrice de quotas de cette mati\u00e8re responsable, en grande partie, de l’effet de serre\u00a0\u00bb.<\/p>\n

\u00ab\u00a0Fin 2006, la tonne de carbone se vendait 20 euros\u00a0\u00bb, affirme Bernard Martin, qui pense qu’ainsi on pourrait rendre la terre agricole aussi lucrative que le terrain \u00e0 construire!<\/p>\n
