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.

1. Rain-Induced Landslide
On risk exposure to rain-induced landslides, the figure shows that 139,464.03
hectares (28.96%) are exposed under the high level, 308,100.98 hectares (63.98%) are
under the moderate risk and 34,024.18 (7.06%) are under the low level risk exposure.
Protection forest has the highest percentage of exposure under the high level
(68.42%), agricultural lands under the moderate level (75.32%) and built-up areas under the
low risk level (39.89%). On the contrary, built-up areas have the lowest exposure rate
(2.29%) under the high level and protection forest (31.58%) under the moderate and totally
not exposed under the low risk level.

4. Mindanao Fault Daguma Extension
a. Liquefaction
Liquefaction may cause damage to around 25% of the agricultural area
against the total land use in the province if ever there is movement of the Mindanao
Fault Daguma Extension. Agriculture is highly exposed in the low risk level wherein
it registered 56.17% which is equivalent to 89,163.19 hectares. Production forest is
100% exposed under the low risk level.

a. Earthquake-Induced Landslide
Exposures of the different sectors are notably high in the low risk level
wherein built-up areas registered 100% exposure, agriculture, production forest and
protection forest registered a percentage of more than 90% and other land use area
registered a percentage of 89.44%.
Under the high and moderate levels, percentages of exposures are at very
minimal figures.

a. Groundshaking
Again, agriculture area has the highest percentage of exposure if
groundshaking will occur in the province caused by the movement of the Mindanao
Fault Daguma Extension while protection forest is free from exposure.

Proposed Land Uses
1. Flood
On the proposed land uses, protected wetland/marsh is added to the existing land
uses. This sector is highly exposed in the high risk level (99.18%) but free from
exposure in the low risk level. Protection forest is highly exposed in the moderate level
while other land use is exposed in the low risk level.

2. Rain-Induced Landslide
Agriculture area is again the most affected in the proposed land use as against the
total land use area in the province. Protected wetland/marsh is absolutely exposed
under the moderate level but free from exposure in both high and low risk levels.
Protection and production forests are the most affected in the high risk level, agriculture
in the moderate and built-up areas in the low risk level.
