\"Images_4\"<\/a> Les \u00e9tudes men\u00e9es par l’ARS (agence de recherche agronomique), montrent que les patates douces<\/a> et le manioc fournissent presque trois fois plus d’hydrate de carbone \u00e0 l’hectare que le ma\u00efs (10.5 tonnes contre 3.7 \u00e0 l’hectare).
Il se rapproche du rendement de la canne \u00e0 sucre.
Mais le triomphe de l’\u00e9thanol-ma\u00efs aux USA s’explique avant tout par la force du lobby du ma\u00efs.
Les producteurs de cette c\u00e9r\u00e9ale sont puissants et organis\u00e9s<\/a>, ce qui compte plus que le rendement, minable  que l’on constate.<\/p>\n

Le Br\u00e9sil est dans la m\u00eame probl\u00e9matique, la canne \u00e0 sucre s’y d\u00e9veloppe car l’industrie y \u00e9tait d\u00e9j\u00e0 forte AVANT le triomphe de l’\u00e9thanol.
La crise financi\u00e8re que nous connaissons rendra sans doute de grands services \u00e0 cette fili\u00e8re en d\u00e9truisant tous les errements.
Reste bien entendu, le fait que la crise alimentaire qu’elle a cr\u00e9e n’en serait pas r\u00e9gl\u00e9e et sans doute aggrav\u00e9e.
Une ressource rentable, moins consommatrice en entrants et en eau, serait plus viable, ce qui conduirait \u00e0 l’aggravation de la concurrence homme\/voiture. <\/p>\n
