Is Climate Change A threat Food Security?

GIS Attempts to answer

GIZ

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?

Research:

Why Sea Level Rise Spatial Modelling

• Reliable and well documented sources

•Available Metadata

Baseline Data1. Digital

Terrain Model • 10cm interval• 10 X 10

pixels

Visual Dimension of a 10m X 10m House

10m

10m

Baseline Data2. PCSSP Sea Level Rise Scenario

• 2030 – 37cm• 2060 – 67 cm• 2100 – 117cm

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
