Spatial Modelling:1. Topography of the coastal areas or land
elevations 2. Would you like a full study using numerical
modelling tools to investigate the most suited location on the coast for taro patches according to probability of inundation from the sea and risk of erosion?

Baseline Data3. Mean sea level as the bench mark for predicting sea level rise
• 0.74m Average mean sea level
• 1.76m highest average mean sea level – Can be used to derive another simulation
