Guilty or Scapegoat? Land Consolidation and the Hedgerow Decline

Abstract

Le remembrement est un outil politique standard pour réduire la fragmentation des terres par la redistribution spatiale des droits de propriété ; cependant, le risque d'effets négatifs sur le paysage soulève des inquiétudes quant à sa durabilité environnementale. Cette étude examine les impacts paysagers du remembrement sur le réseau de haies de Basse-Normandie, en France. En appliquant une stratégie de différences en différences échelonnées sur une enquête longitudinale (1972-2010), nous montrons que le remembrement a conduit à une réduction significative de la densité des haies de -14,3 m/ha (erreur standard : 2,33), ce qui représente 13,7 % de la baisse globale observée dans les zones remembrées. Nos résultats suggèrent également un impact décroissant avec le temps de consolidation et le temps écoulé depuis la consolidation, un impact croissant avec une densité initiale de haies plus élevée, aucun effet d'entraînement, et un impact négatif sur la connectivité du réseau. Nos résultats confirment que le remembrement a contribué de manière significative au déclin des haies, mais ils remettent en question les croyances dominantes sur sa part de responsabilité parmi d'autres facteurs de changement du paysage.

Land consolidation is a standard policy tool to reduce land fragmentation through the spatial redistribution of property rights; however, the risk of adverse effects on the landscape raises concerns about its environmental sustainability. This study investigates the landscape impacts of consolidation on the hedgerow network of Lower Normandy, France. Implementing a staggered difference-in-differences strategy on a longitudinal survey (1972-2010), we show that consolidation led to a significant reduction in hedgerow density of -14.3m/ha (standard error: 2.33), accounting for 13.7% of the overall decline observed in consolidated areas. Our results also suggest a diminishing impact over time of consolidation and time since consolidation, an increasing impact with higher initial hedgerow density, no spillover effect, and a negative impact on network connectivity. Our findings confirm that land consolidation has significantly contributed to the decline of hedgerows, but they challenge prevailing beliefs about its share of responsibility among other factors of landscape changes.
