DRR/CCA INTEGRATION TO LAND USE

(note: introduction on protection land use, protection areas, settlements etc)

Risk Exposure of Existing Land Uses

1. Flood

The total land use type area of the province on agriculture, built-up areas, other land

use, production forest and protection totalled to 633,309.11 hectares. Of this total,

490,983.74 hectares or 77.53% are exposed to flood hazard wherein 147,956.66 (30.13%)

are at high risk, 201,885.42 hectares (42.95%) are under the moderate and 132,141.67

hectares (26.91%) are under the low risk exposure.

Agricultural lands are the biggest sector that is highly exposed considering the

province is an agricultural area and it registered higher exposure percentage under the

moderate level. On the other hand, protection forest is not exposed under the high risk level

but registered highest percentage of exposure under the moderate level.

3. Banga Fault

a. Liquefaction

On liquefaction due to the movement of Banga Fault, the protected wetland/marsh

has a very high rating at 91.45% in the high risk level, production forest has high ratings

in both moderate and low risk levels while protection forest is free from exposure in all

levels.

On earthquake-induced landslide, all sectors have either minimal or zero exposure

rating in the high risk level. Agriculture, built-up areas, other land use, production forest

and protection forest registered very high exposure ratings under the low risk level while

protected wetland/marsh is spared from exposure in all levels.
