Drie decennia natuurrealisatie in de Krimpenerwaard : inzicht in de werking en doorlooptijd van grondinstrumenten

Summary

Three decades of nature restoration and conservation in Krimpenerwaard: Insights into the functioning and timelines of land policy instruments For the Netherlands Environmental Assessment Agency (PBL), Wageningen Environmental Research (WENR) and Kadaster (Netherlands Cadastre, Land Registry and Mapping Agency) studied the functioning and timelines of strategies for realising part of the national ecological network (NEN) in Krimpenerwaard. This area process has run for more than thirty years and has involved five consecutive implementation strategies and their associated land policy instruments, such as voluntary transfer of land ownership, land parcel exchange, ‘self-realisation’ (nature restoration and conservation management by the private landowner) and expropriation. What influence did these strategies and instruments have on making land available for nature restoration and what were the timelines involved? We found that each change of strategy delayed the process and that a strategy involving the purchase of land with full compensation speeds the process up. Important conditions for a successful area process were the availability of a mix of instruments, a dedicated budget and a land bank. Ultimately, the key to successful implementation was 1) compelling landowners to choose between self-realisation or selling their land with full compensation, with expropriation as the final resort, and 2) the availability of self-realisation instruments such as land lease and the possibility of partially writing down land value.
