Il y a cette s\u00e9cheresse actuelle, inhabituelle en hiver. Et d\u2019autres ph\u00e9nom\u00e8nes qui d\u00e9montrent que nous sommes en train de vivre une transformation rapide du climat : la canicule tardive de septembre, les temp\u00e9ratures tr\u00e8s sup\u00e9rieures \u00e0 la normale (+5,5\u00b0) de d\u00e9cembre. Cette mutation semble s\u2019acc\u00e9l\u00e9rer, m\u00eame si cela fait vingt ans que les ph\u00e9nom\u00e8nes se cumulent.<\/p>\n\n\n\n<p>De plus, la France, pays habituellement temp\u00e9r\u00e9 et gros consommateur d\u2019eau, notamment pour son agriculture, est en train de vivre une transformation plus importante et impactante que le reste du monde.<\/p>\n\n\n\n<p>Mais peut-on encore \u00e9chapper \u00e0 une s\u00e9cheresse historique cet \u00e9t\u00e9 ? Des pr\u00e9cipitations soudaines, tr\u00e8s importantes, peuvent changer la donne. C\u2019est ce qui s\u2019est d\u00e9j\u00e0 produit en juin 2016, une des ann\u00e9es les plus chaudes jamais recens\u00e9es en France mais tr\u00e8s pluvieuse juste avant l\u2019\u00e9t\u00e9. Ce qui est nouveau c\u2019est que les situations peuvent \u00e9voluer tr\u00e8s vite. En 2018, apr\u00e8s une ann\u00e9e 2017 de s\u00e9cheresse, les pluies de janvier ont \u00e9t\u00e9 sup\u00e9rieures \u00e0 celles de 1910, l\u2019ann\u00e9e des grandes crues de la Seine. Nous avions 30 % d\u2019exc\u00e9dents en eau en abordant le printemps. Mais trois semaines de canicule ont fait basculer la situation dans l\u2019autre sens. L\u2019ann\u00e9e a finalement connu une s\u00e9cheresse record ! Car m\u00eame avec les pluies cons\u00e9quentes, les nappes phr\u00e9atiques n\u2019arrivent pas \u00e0 \u00eatre recharg\u00e9es.<\/p>\n\n\n\n<p>Sans compter que nous entrons dans une p\u00e9riode de grande inconnue climatique. Le ph\u00e9nom\u00e8ne La Nina qui devait \u00eatre un syst\u00e8me plus refroidissant pour nous ne nous a pas emp\u00each\u00e9 de cumuler des records historiques de temp\u00e9ratures . Et nous sommes en train de basculer dans le ph\u00e9nom\u00e8ne El Nino qui pourrait apporter des temp\u00e9ratures plus caniculaires.<\/p>\n\n\n\n<p>Nous allons donc vers une mutation rapide, o\u00f9 la ressource hydrique va \u00eatre un enjeu majeur. Pour pr\u00e9server cette ressource il y a des comportements que nous ne pourrons plus avoir. Il faut arr\u00eater de \u00ab piller \u00bb les nappes phr\u00e9atiques avec le risque de les voir disparaitre.
