Towards a simple integrated model for the re-wetting of nature reserves

In the Netherlands hydrological measures are taken to raise the groundwater level in nature reserves that are suffering from groundwater levels that are to low, i.e. from ‘desiccation’. These measures often lead to wet damage to agriculture in adjacent areas. There is, however, a lack of insight into these costs in relation to the benefits to nature. In this study a simple model prototype is presented in which economy, ecology and hydrology are integrated. The model provides insight into the cost-effectiveness of restoration projects that reduce desiccation of nature reserves. It shows that the current policy goal to reduce the desiccated surface area will not maximize the increase in the ecological conservation value.
