What is Carmen's Physical Profile, Topography and Climate
Carmen town is picturesque with its verdant undulating terrain intermittently broken by mountain ranges and plateaus. The topography in the area is generally gently sloping to rolling (with slope of 3-18%) as this category comprises 62% of the total land area.
These areas are predominant in the eastern to northern portion and the southwestern portion of the municipality. Steep hills are predominant in the northern portion of the municipality.
At the southwest portion, the almost uniform-shaped hills known worldwide as the “chocolate hills” stands out in a plain surrounded by rice paddies. These rice paddies are wonderful backdrops to the “chocolate hills” which turn a dark chocolaty brown during the summer months.
Most of the “chocolate hills” are bare except for some grass although the bases of the hills have thick vegetation of tropical shrubs and trees including coconut. Grasslands and coconuts mostly cover the steep mountains and hills at the northern portion.
The eastern and southeastern portions, characterized by a rolling to moderately steep terrain, are planted to corn and cassava. Non-irrigated rice paddies are found on the western and southern parts.
