A Less Simplistic Approach to Landscape Complexity
Anouch Missirian

Abstract:

La tendance à la consolidation des terres et à l’homogénisation du paysage agricole peut être individuellement rationnelle, par exemple du fait de l’existence d’économies d’échelle, ou pour ne produire que la culture la mieux adaptée aux conditions locales. A l’échelle d’un paysage, en revanche, l’on pourrait prévoir que la généralisation de ce comportement, i.e. une simplification radicale du paysage agricole, pourrait conduire, en théorie, conduire à la présence accrue d’insectes ravageurs, en favorisant leur développement et en nuisant à leurs prédateurs. Cette pression accrue engendrerait des coûts privés pour les agriculteurs (pertes de rendements, pesticides). Cette étude vise à évaluer et quantifier cette relation putative entre complexité du paysage agricole et pression des ravageurs dans le cas des Etats-Unis.
