Malgr\u00e9 les diff\u00e9rentes incitations \u00e0 r\u00e9duire l\u2019usage des produits phytosanitaires (PP), le secteur viticole reste tr\u00e8s consommateur en pesticides. L\u2019objectif de ce projet est l\u2019\u00e9laboration de nouvelles strat\u00e9gies de r\u00e9duction d\u2019usage et d\u2019impact des PP en milieu viticole, qui soient territorialis\u00e9es, durables et acceptables par la diversit\u00e9 des acteurs agricoles. Les strat\u00e9gies envisag\u00e9es reposent sur trois principes\u00a0:<\/p>\n

    \n
  1. la combinaison de leviers de r\u00e9duction d\u2019usage \u00e0 l\u2019\u00e9chelle parcellaire (ex.: conduite bas-intrants, biocontr\u00f4le) avec l\u2019implantation de zones tampons limitant la dispersion des PP \u00e0 l\u2019\u00e9chelle paysag\u00e8re,<\/li>\n
  2. la modulation territoriale des leviers parcellaires en fonction des contraintes d\u2019exploitation viticole (ex. sol, climat, objectifs de rendements) afin de favoriser l\u2019acceptabilit\u00e9 et la durabilit\u00e9 des leviers envisag\u00e9s,<\/li>\n
  3. la mise en place d\u2019une approche participative \u00e0 l\u2019\u00e9chelle territoriale pour d\u00e9finir les r\u00e8gles de modulation des leviers ainsi que les objectifs de r\u00e9duction d\u2019impact collectif sur les \u00e9cosyst\u00e8mes et les riverains.<\/li>\n<\/ol>\n

    Le projet est exp\u00e9riment\u00e9 sur le bassin versant du Rieutort (H\u00e9rault). La d\u00e9marche participative associe un groupe d\u2019acteurs viticoles et un groupe d\u2019experts (agronomes, hydrologues\u2026), qui \u00e9laborent en interaction les strat\u00e9gies selon les principes pr\u00e9c\u00e9dents. Elle s\u2019appuiera sur un diagnostic d\u2019impact (a) environnemental des strat\u00e9gies \u00e9labor\u00e9es par simulation num\u00e9rique de l\u2019exposition des riverains et des contaminations hydrologiques et (b) agronomique (\u00e9valuation des risques de pertes de rendement). Les strat\u00e9gies paysag\u00e8res r\u00e9pondant le mieux aux crit\u00e8res de r\u00e9duction d\u2019impact environnemental de durabilit\u00e9 productive et d\u2019acceptabilit\u00e9 feront l\u2019objet d\u2019une diffusion par les organismes consulaires agricoles au plan national et r\u00e9gional.<\/p>","protected":false},"author":7,"featured_media":0,"template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"default","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"categories":[82],"class_list":["post-1579","projets-de-recherche","type-projets-de-recherche","status-publish","hentry","category-projet-termine"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.umr-lisah.fr\/en\/wp-json\/wp\/v2\/projets-de-recherche\/1579","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.umr-lisah.fr\/en\/wp-json\/wp\/v2\/projets-de-recherche"}],"about":[{"href":"https:\/\/www.umr-lisah.fr\/en\/wp-json\/wp\/v2\/types\/projets-de-recherche"}],"author":[{"embeddable":true,"href":"https:\/\/www.umr-lisah.fr\/en\/wp-json\/wp\/v2\/users\/7"}],"version-history":[{"count":6,"href":"https:\/\/www.umr-lisah.fr\/en\/wp-json\/wp\/v2\/projets-de-recherche\/1579\/revisions"}],"predecessor-version":[{"id":2019,"href":"https:\/\/www.umr-lisah.fr\/en\/wp-json\/wp\/v2\/projets-de-recherche\/1579\/revisions\/2019"}],"wp:attachment":[{"href":"https:\/\/www.umr-lisah.fr\/en\/wp-json\/wp\/v2\/media?parent=1579"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.umr-lisah.fr\/en\/wp-json\/wp\/v2\/categories?post=1579"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
