Chapter 11 PHILIPPINEPOPULATION

Celeste Roderno-Desingaño

Population

Population is a group of similar species living in a certain place at the same time

Population is the interaction between the organisms that causes a population to change.

Characteristics of Population

1. Size

2. Density

3. Distribution

Characteristics of Population1. Size

Pertains to the number of individuals in a population

Factors that Contribute to the Size of a Population

1. Natality – the number of species that are born

2. Mortality – the number of species that die

3. Migration – the transfer of species from one place to another

a. Immigration – the number of species that entered the land

b. Emigration – the number of species that leave the land

Characteristics of Population2. Density

Defined as the number of individuals of a species living in a particular area of that population.

Example: 250 horse/hectare

Population density increases when the factors are favorable to the population and decreases when they are unfavorable.

Population density may vary from year to year and is determined by external factors

Characteristics of Population3. Distribution

The arrangement of the individuals of a population within a particular space.

Random Distribution – There is no specific order in random distribution, the organism is spread throughout the area without an over-all pattern.

Uniform Distribution – the organism are evenly distributed over an area.

Clumped Distribution – the organism are concentrated in an area. It may offer the population protection from enemies.

Projected Philippine Population Philippine population would continue to grow,

increasing from 76.5 M, as of the latest population census conducted in May 2000, to 141.7 M in 2040

The population is projected to grow by 1.95% in the 2005-2010 periods, from 85.3 M in 2005 to 94 M in 2010

In 2010, CALABARZON would have 11.9 M people, while NCR, 11.6 M. By 2040, CALABARZON would have 18.5 M and Central Luzon would have 15 M

Reasons why Filipino have an Immense Growth of Population

Tradition of having big families – Filipino prefers to have big family of 6-12 children. They believe that their children will lessen their loneliness during old age, even though half of them become ungrateful. Children are considered priceless gifts of God, more than wealth.

Question of Gender – parents want to have their first born child to be a boy. They ignore family planning, because they want to have boys as their next child if they have only girls.

The male macho image – Most Filipino feel that masculinity lies on the ability to impregnate their wives frequently.

Educational background – The less educated the people, the more they have children. The more educated the people, the fewer children they want.

Reasons why Filipino have an Immense Growth of Population

Unsatisfactory/Ineffective family relationship – There is an increase in Filipino population because they believe that contraceptives are hindrances to a full sexual pleasure of a couple and that they endanger the health of women. They feel that family planning is an intrusion to private affair of the married couple.

Economic reasons – The family tends to choose the number of children they want for economic reasons. Children help family to raise food, haul water and work for wages outside the home. People tend to have more children because they feel it improves their economic security.

Contraceptive methods – Catholic Church disapproves the use of contraceptive methods in family planning.

Environmental problem Increase in population means increase in waste materials thrown in

the environment and there is a greater degradation and deterioration of nature.

Social problem Over population may result to prostitution, drug addiction, crime,

juvenile delinquency, suicide and others due to lack of opportunity to have a nice stable job because of too much competition.

Economic problem The economists consider population growth a problem because it

hinders the country’s effort to satisfy the needs of the citizens. Educational problem

It is a problem when the Philippine government cannot provide enough education, classrooms, school facilities, education materials even qualified teachers.

Problems on Population Growth in the Philippines

Health problem The health condition of the people is being affected due to

adverse conditions: prevalence of disease, epidemics and undernourishment.

Spiritual and moral problem Due to overpopulation, people become materialistic and

liberalistic. The morality and spirituality of young generation seem rapidly declining.

Problem of food supply Overpopulation leads to problem on how to provide for

people’s basic needs. Problem of destruction of nature

Population growth may result to fast deteriorating environmental resources, such as virgin forest.

Agricultural lands are converted into industrial sites, biodiversity becomes endangered.

Problems on Population Growth in the Philippines

Impact of Population in Environment

1. Land use Patterns

When there is an increase in population there is also an increase in waste materials thrown on the environment and there is a greater degradation and deterioration of nature.

Fulfilling the resource requirements of a growing population ultimately requires some form of land use change—to provide for the expansion of food production through forest clearing, to intensify production on already cultivated land resulting to deforestation thereby:

increasing the frequency and severity o9f floods and soil erosion degradation of soil by using of fertilizers if land will be converted

to agricultural use habitat fragmentation leading to species decline.

Requirement to develop infrastructure necessary to support increasing human numbers.

Impact of Population in Environment

2. Global Climate Change Recent years have been among the warmest on record. Research

suggests that temperatures have been influenced by growing concentrations of greenhouse gases, which absorb solar radiation and warm the atmosphere. Research also suggests that many changes in atmospheric gas are human-induced.

Contributions related to industrial production and energy consumption lead to carbon dioxide emissions from fossil fuel use.

Land-use changes, such as deforestation affect the exchange of carbon dioxide between the Earth and the atmosphere

Some agricultural processes, such as paddy rice cultivation, livestock production are responsible for greenhouse gas releases into the atmosphere, especially methane.

Impact of Population in the Developing Country

There will be an increase in working age population and this will give the country an opportunity to develop its human capital.

The government and private sector will have to start planning for their education and health needs as well as for their employment.

A growing unemployment rate would mean a rising crime rate, insecurity and instability.
