Population Policies in Australia and Russia for sustainable development

Australia: Sustainable Population Strategy

-          The objective:

Improve the well-being through management of population change’s impacts.
The thing is not to stop the growth, but address the issues that it generates in an adequate way.
Seeks to identify and take action in areas where population change may lead to unsustainable environment and natural resource management practices.

-          How it is supposed to address the issues:

Carefully planned, sustainable management of this natural capital is essential to ensure it remains healthy and available to current and future generations

-          How do the policies will affect population growth?

  •         The Sustainable Population Strategy will considered, and thus, affect directly aspects of population dynamics such as fertility, life expectancy, internal movements, and migration levels.
  •          It will intend to look after the condition of different growth rates and conditions for different areas of the Australian territory.
  •          It will work with the National Urban Policy that will make able to maintain the urban population, which represents almost the 80%, by addressing and controlling issues, such as: water scarcity, service delivery, food security and health services.
  •          The research for the strategy has given out results that show that the increase of Australian food production in the last decades are due to an increase in efficiency and productivity, rather than the disposition of more agricultural land. The strategy intends to exploit productivity in order to handle the increasement of population.
  •          Carbon dioxide emissions will be lowered as the strategy plans a reduction in the pollution per capita. This will lead to greener practices among the population, better living standards and the move towards sustainable power sources.
  •          The country establishes a great importance in the population growth due to the need of work force.
  •          Migration is an important factor to consider as it represents skilled workforce, innovation, a dynamic society with different views, connection with other nations, and foreign capital in the Australian economy.

The Strategy would set three different independent panels to look at population change through different lenses:
  1. Demography and liveability
  2.  Productivity and prosperity
  3.  Sustainable development


Russia policies of population strategy

In recent years Russia’s government, led by President Vladimir Putin, has established new population and sustainable development policies that are intend to response to the issues that the country is facing. A shortening population, lack of workers

Russian government feels that the worst problem is the issue is the population crisis of implosion. The government has decided to implement policies that will increase the birth and fertility rate of the country by trying to increase the number of children per family.

A repatriation program has been set by the government in order to bring back the former Russians that have left the country looking for specialized opportunities aboard. The program includes monetary incentives, social benefits and employment opportunities.

There is a proposal to change he immigration policies in order to make them friendlier with foreigners, increasing the appeal of the country to skilled and non-skilled outsiders.

Russia is the second nation that receives more immigrants, being USA the first one.  A great part of these immigrants are illegal. Illegal immigrants are subject to bad job possibilities and don’t contribute the activation of the economy. New migration policy will control the access of illegal immigrants and will concede legal registration and working permit to the greater part of the illegal immigrants that are already in Russia. The law defines quotas for migrant sending countries and high penalties for employers who illegally employ migrants.

Population Pyramids

They are a useful graphic, also called age-sex pyramids, representation that give us the information to analyze population distribution and population change

Population numbers are the x-axis and age groups are on the y-axis.

*As we can see it can also be focused on only one sector of the population.

It shows:

  • How many individuals are alive in different age groups cohorts in a country or region for any given year.
  • Show the male-female ratio

Types of Pyramid Shapes.

Stage 1. Expanding – High CBR *(, rapid fall in each upward age group due to high CDR, short life expectancy.

Stage 2. Expanding – High CBR, fall in

CDR as more individuals live to the middle age, slightly life expectancy.

Stage 3. Stationary – declining CBR, low CDR, more individuals live to old age.

Stage 4. Contracting – low CBR, low CDR, higher dependency ratio (those that cannot work), longer life expectanxy

LEDC’s tend to be in stage 1 and 2, while MEDC’s are in the 3 and 4 stages.

Measures of Population Changes

Population change around time by the action of factors such as birth and death rate and migration.

The basic rate for measuring the fluctuations in population are the following:

Crude Birth Rate (CBR)

The number of births per 1000 individuals in a population per year.

Number of births x 1000
population size

Crude Death Rate (CDR)

The number of deaths per 1000 individuals in a population per year.

Number of deaths x 1000

population size


Natural Increase Rate

NIR = (CBR - CDR) / 10

Doesn’t consider immigration and emigration.


Doubling time

The time in years it takes a population to double its size.

Doubling time = 70 / NIR


Total Fertility Rate (TFR)

It is the average number of children that each woman has over her life time. It shows the potential of population change.

    • A TFR > 2.0 results in a population increase
    • A TFR < 2.0 results in a population decrease
    • A TFR = 2.0 results in a stable population

In developing countries, the fertility rate is usually higher than in MEDC’s


Humans impact on the environment is not just given out by its growth, but also by resource use and pollution. It’s impact is affecter by:

  • It’s affected by the amount of wealth
  • Resource desire
  • Resource need

Individuals in a population, specially in a human population, interact with the environment in different ways. We cannot generalize for all the organisms within a population.

Wait for a detailed list of identification of resource use and waste profiles in a further post.
