E-BOOK Changement climatique
GRANDES CULTURES

Dans le cadre de la journée d'échange de pratiques sur l'adaptation au changement climatique entre conseillers du projet ClimaTerra et du projet Climate Smart Advisor de janvier 2025, des ateliers thématiques ont été réalisés pour réfléchir sur les leviers techniques d'adaptation à mettre en place sur les exploitations agricoles. Plusieurs thématiques ont été abordées : gestion du sol, gestion de l'eau, fertilisation, gestion du troupeau, alimentation du troupeau, bâtiments d'élevage, grandes cultures, agroforesterie. Ces fiches remontent les informations échangées lors de ces ateliers d'échange entre pairs. https://rd-agri.fr/detail/DOCUMENT/chambres_d'agriculture_322313

Arvalis a estimé les émissions de gaz à effet de serre (GES) de différentes formes d'azote minéral à partir des références de la méthode Label Bas carbone-grandes cultures. L'exercice montre que le choix des engrais est loin d'être anodin sur les émissions de GES des cultures et des exploitations.

En fvrier 2025, l\u2019ADEME a publi une tude de march des produits biosourcs, offrant un clairage indit sur un secteur en forte croissance. Entre innovations technologiques, transition cologique et souverainet industrielle, ces matriaux d\u2019avenir s\u2019imposent progressivement comme des alternatives crdibles aux produits ptrosourcs. Mais quels sont leurs vritables atouts ? Quels sont les secteurs en pointe ? Et comment acclrer leur adoption ?

Si elles tirent vers le bas le bilan carbone de l'agriculture, les machines restent indispensables à l'activité agricole. Pour réduire leur impact, la mise en commun des équipements, à travers les Cuma, ou la délégation des travaux, peut constituer une réponse aux enjeux environnementaux, à condition de lever certains freins.

Diminuer les gaz à effet de serre de 20 % pour l'amont et de 24 % pour l'aval à horizon 2030 : ce sont les objectifs de la feuille de route carbone d'Intercéréales et Terres Univia. Pour y arriver, plusieurs leviers ont été identifiés.

Des témoignages de producteurs en agriculture biologique qui adaptent leurs pratiques face au changement climatique, en 4 podcasts. https://www.produire-bio.fr/articles-pratiques/climat-la-bio-lance-son-podcast-cultiver-lavenir/

Les arbres et les haies constituent une mesure d\u2019adaptation des systèmes agricoles face au changement climatique. Zoom sur les résultats récents d\u2019une étude en exploitations bovines dans le Nord-Pas de Calais. https://bretagne.chambres-agriculture.fr/mes-actus/toutes-les-actus-agricoles-bretonnes/detail-de-lactualite/actualites/les-arbres-champetres-des-atouts-face-aux-enjeux-climatiques/

Même si la Bretagne n'est pas la région la plus pénalisée par l'augmentation des épisodes de sécheresse, les agriculteurs savent que la disponibilité en eau va se compliquer. Les adhérents du Ceta 35 ont décidé de réfléchir en groupe aux nécessaires changements de pratiques pour y faire face.

[...] Sur pois et féverole, la surveillance des insectes ravageurs est primordiale dès le début de cycle en sortie d'hiver. Mais le changement climatique peut changer la donne et imposer de nouvelles stratégies. Avec le changement climatique, la hausse des température [...]

Comment valoriser le carbone stocké par les haies ? C'est l'objectif du Paiement pour Service Environnemental (PSE) Haies, Carbone et Co-bénéfices proposé par l'association Symbiose Normandie. Ce PSE est une opportunité pour soutenir les agriculteurs dans la gestion durable des haies bocagères et répondre à l'enjeu de maintien du bocage et des services environnementaux associés.
