The highlands in the middle of Cebu which extends from the city in
the east to Balamban/Asturias in the west presents a beautiful mixture of
protected landscapes with good secondary forest cover, and crop production
systems consisting of orchard particularly mango, annual crops, vegetables and
cut flowers.
Beautiful views of the Cebu Highlands |
The very beautiful scenery reminds visitors of Baguio City or some
foreign places like Indonesia or Taiwan. Clearly observable even on distant
undulating slopes are the mango trees which are adapted to the agroclimatic
conditions of Cebu.
Mango trees are abundant in certain parts of the landscape |
Cebuanos are widely known to be corn eaters. This explains why
corn is the most widely grown grain crop in the highlands. On red acidic soils
from igneous rocks as well as on dark calcareous soils from limestone, nutrient
deficiency symptoms (N, P) are clearly observable. But the crop is still able
to produce a relatively good yield.
Large and small corn plantations are common in the highlands |
On degraded limestone slopes on the western side close to
Balamban, coconut plantations can be seen which are also showing nutrient
deficiency symptoms most probably nitrogen and iron as indicated by the
yellowing of leaves (plant analysis data from comparable lands in southern
Leyte indeed revealed both nitrogen and iron deficiencies).

But the most impressive crop production venture by the people in
the highlands is the one which consists of cut flowers (e.g. Chrysanthemum) and
vegetables (lettuce, cabbage, chayote, etc). The cut flowers are delivered to the
city while the vegetables are sold in the city and in local stores along the
highway.
Stores selling the farm products are found along the highway |
It must, however, be mentioned that although contour farming can
be seen on some steep slopes, unsustainable cultivation practices can be clearly observed.
The most obvious is the plowing or planting of crops along the slope (top to bottom
orientation). This practice promotes soil erosion and loss of nutrients from
the soil. This should be taken seriously as this could lead to severe soil
erosion on the slopes accompanied by the siltation of the streams below. It could
have a long-term impact on the water quality and quantity in the streams.
