Abstract

Wetlands play a crucial role in the agricultural landscapes of Canada's Prairie Pothole Region (PPR) but are being lost to agricultural and urban development. There is increased interest from governments and conservation organizations in restoring previously drained wetlands, but these projects are costly and associated with intangible ecosystem service benefits. We conduct a stated preference survey of 1,999 people in Alberta, Saskatchewan, and Manitoba to elicit preferences for provincial wetland restoration programs using an incentive compatible valuation question. We estimate welfare measures from these choices and find that people are willing to pay on average $368 per year to restore 10% of lost wetlands in their home province when they feel their choice is consequential. Willingness to pay (WTP) estimates are consistently highest in Manitoba and exhibit heterogeneity with respect to respondent characteristics in all provinces. Our results show that the aggregated per hectare social benefits of wetland restoration can exceed the per hectare costs of restoration, but the per hectare social benefits diminish as restored wetland area increases. Les milieux humides jouent un rôle essentiel dans les paysages agricoles de la région des Prairie Potholes (PPR) au Canada, mais ils disparaissent progressivement en raison du développement agricole et urbain. Les gouvernements et les organisations de conservation manifestent un intérêt croissant pour la restauration des milieux humides anciennement drainés, mais ces projets sont coûteux et associés à des avantages écosystémiques souvent intangibles. Nous réalisons une enquête de préférences déclarées auprès de 1 999 personnes en Alberta, en Saskatchewan et au Manitoba afin de recueillir leurs préférences concernant des programmes provinciaux de restauration des milieux humides, en utilisant une question de valorisation incitative compatible. Nous estimons les mesures de bien‐être à partir de ces choix et constatons que, lorsque les répondants perçoivent que leurs décisions ont des conséquences réelles, ils sont prêts à payer en moyenne 368$ par année pour restaurer 10% des milieux humides perdus dans leur province. Les estimations de disposition à payer (DAP) sont systématiquement les plus élevées au Manitoba et présentent une hétérogénéité liée aux caractéristiques des répondants dans toutes les provinces. Nos résultats montrent que les avantages sociaux agrégés par hectare issus de la restauration des milieux humides peuvent dépasser les coûts par hectare de ces projets, mais que ces avantages diminuent à mesure que la superficie restaurée augmente.
