Build-up of the model

 

To determine the health effects of vegetation, the percentage of vegetation within a one km radius around every cell needs to be calculated. This can be done in two ways − one calculation includes agricultural areas surrounding cities and towns, one excludes agricultural areas. The calculation is done as followed:

Build-up of the model

 

The deposition velocity depends on the type of vegetation and land cover. The type of vegetation is based on the maps with the percentage of trees, shrubs and low vegetation/grass. The land cover is taken from the LCEU map. The average deposition velocity of a grid cell is estimated as:

Soil drainage

Input maps with the average minimum (GLG) and maximum (GHG) groundwater level (NHI,2006) are reclassified into nine soil drainage classes, according to Finke et al. (2010) as given in Figure 1. As the groundwater level maps do not cover the Wadden islands in the north of the Netherlands, the groundwater level from the soil map is reclassified into the same nine hydrological classes according to a reclassification table based on expert judgement (available on request). In both cases, a distinction has been made between two texture types: light soils and heavy soils as defined in Table 4. The nine drainage classes have been regrouped into four drainage groups according to Table 5 in order to estimate the annual increment.

Additional relevant co-benefits

Currently, seven co-benefits are calculated in the Green Benefit Planner extension in the Climate Adaptation Support Tool. These benefits are quantified both physically and monetarily. There are a number of co-benefits that cannot be quantified yet, but are important regarding climate adaptation measures (also see the CBA report1). Additional co-benefits that might be relevant to policy assignments are given below:

 

Biodiversity

At present, biodiversity cannot be quantified in the Green Benefit Planner. However, adding green and blue due to climate adaptation measures can have a positive effect on animal and plant biodiversity in municipalities. The increase in biodiversity, on its turn, can have positive effects on the delivery of other relevant co-benefits/ecosystem servicers such as pollination.

 

Recreation

Currently, only the increase in physical activity in green environments and the health care benefits of cycling for commuting purposes due to green are quantified. Green, however, can also contribute to other forms of recreation. These other forms of recreation are not quantified in the tool, but can be an important co-benefit to climate adaptation measures and contribute in the decision making process of applying these measures.

 

Social cohesion

Increasing the amount of green in the environment by means of climate adaptation measures offers possibilities for creating meeting places for local residents. This can increase the social cohesion and liveability of neighbourhoods.

 

Experience value

Changing the public space by means of climate adaptation measures can increase the attraction of an area, especially with ‘green’ and ‘blue’ measures. Thus, these measures can improve the experience value of the public space, which can have positive effects on local residents in and around this area.

 

Noise reduction

Green has a dampening effect on noise disturbance caused by traffic, for instance. The reduction in noise disturbance reduces stress of local residents that live in and around areas where  ‘noise dampening’ green is implemented.

 

Changing subsidence / CO2 emissions of peat

If climate adaptation measures change the ground water level in peat areas, they have an effect on the emission of CO2 and subsidence of these peat soils.

 

Pollination

The implementation of green can enhance or increase the habitat for different insect species that contribute to pollination. In the last years, the numbers of these pollinators have dropped significantly, thereby threatening the production of crops and other plant species. Creating habitat for these species through climate adaptation measures can positively contribute to the survival of these species.

 

Increase in investment costs

The investment costs are determined by the measures that are implemented, which can differ per scenario.

 

Changes in management costs of green and grey

Changes in land use from grey/paved functions to green functions result in changes in management costs.
