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.

Against the idealism of carrying capacity

A population model assumes that the use of resources is equal to all of the individuals. The think here is that we are talking about “individuals” not hard numbers. They have different needs and life conditions. That’s why we cannot take the entire population of the world as in uniform conditions in order to establish the carrying capacity (K)
The individual/population resource use is a dynamic principle. We also must we aware that resources vary with time and space. Some of this variations are given by:
  • MEDCs and LEDCs
  • Urban vs. rural
  • Young communities vs. older communities
However we need to manage carrying capacity to our advantage.
It might be trough pollution control
POLLUTION MANAGEMET
Natural income –> Human activity –> wastes –>  pollution
Pollution:the addition of a substance of agent to the environment by human activity at a rate grater that that at which it can be rendered harmless by the environment.
Major sources of pollution
  • Combustion
  • Domestic waste
  • Industrial waste
  • Agricultural waste
Pollution by noise, by heat.
Sources:
  • Point source
  • Non-point source
Detection and monitoring
  • Directly. measure with a particular variable to refer an specific pollution factor. (CO2 presence in the atmosphere)
  • Indirectly. Impact. uses a variable that depends on a specific factor. (e.g. acid rain: a wide range of possibilities to measure the impact; salinity on the atmosphere)
Pollution indicators
  • Biological Oxygen Demand (BOD): amount of dissolved oxygen required to break down the organic material in a water volume through anaerobic or aerobic activity
  • Indicator species (biotic index 1-10) through invertebrates
Three-level model of pollution management.
replace, regulate and restore
Waste management

Food Production and Distribution

 We have already begun talking about the food supply and its unequal distribution. Now let’s discuss the issues arose by this problem and how do they are handled.


Stuff and terms that you might want to know Winking smile
Food security. This expression means that every person in a given area has a daily access to enough nutritious food to have an active and healthy life.
Food insecurity. The opposite of the first one. There are not enough food supply or simply people have not the needed resources to access them.



*This two guys are directly related to the poverty and most be treated by the government in order to secure the insecure and maintain the security.


Undernutrition. The food consumed doesn’t provides enough energy.
Malnutrition. Food has enough energy but lacks certain essential vitamins, minerals or proteins.
Overnutrition. The food consumed exceeds energy use and causes excess of body fats. Yeah… Not big deal in the LEDC’s but we need to take it into account.

Some of the essential components needed to avoid malnutrition are:

Lack of Iron: “Derives into a case of anemia (lack of iron). Increases fatigue, risk of infection and mortal danger at childbirth”. It is necessary for the hemoglobin which captures oxygen and derives it around the body.

Lack of Vitamin A.More likely to get sick or die of common infectious diseases (flu, diarrhea, measles). Blindness” - retina, thus eye-sight dependents on it Vitamins are nutrients, but a catalyzer to the absorption of nutrients.

Lack of Iodine. Affect the processes of the metabolism. It causes stunted growth, metal

Famine. A famine is a situation of severe shortage of food supply in an area accompanied by mass starvation, many deaths, economic chaos, and social disruption. It is typically generated by a catastrophic event.

*It is important to analyze famines’ impact over societies and the environment. Obviously there is a great disruption over the social structure of the community. Food becomes the main asset and its acquisition the final goal. The power if for whom has the control over the limited food supply.

The environment is harmed by the reaction of the population against the famine. People start to slaughter their livestock and grains and, instead of rationalized it, they finished up the remaining food supply.


Now that we know what’s the roll with this terms we can analyze the situation and present the actual management of the issues.

ACTUAL SCENARIO
We have already discuss the possible causes of this unequal food distribution in a previous blog entry. Let’s extended this explanation.

Our food supply is generated in both terrestrial and aquatic systems.

From the terrestrial systems we get grains and other crops, and livestock. Most of the world population’s diet is based upon wheat, rice and corn. As the income of certain sectors of the population increases, more meat and livestock's derivate products, such as milk and cheese, are consumed.

Aquatic systems generate food supply based on fish and shellfish.

It depends on the resources of each community or country which is its main source of food. But these three are the BIG THREE of food supply.

Now, the roll must go back a little bit. By talkin’ about the terrestrial systems of food production, we must take into account the different agricultural techniques that are being used…

Human Populations Around The World

As we have talked before, the resources of Earth are unequally shared between the organisms of human population. Of course all of these is influenced by the three spheres (social, economical and environmental)

Human Development Index

Adopted by the UN Development Programme as a measure of the well-being of a country.

Combines measurements of:

  • Education
  • Life expectance
  • Standards of living
  • Income
  • GDP per capita (Gross Domestic Product)

Countries might also classified based on their industrial development and GDP

MEDCs (used by modern geographers to specifically describe the status of the countries referred to: more economically developed)

  • industrialized nations
  • rich population small poverty
  • high level of resource use per capita
  • relatively low population growth rates

LEDCs  (less economically developed)

  • less industrialized 
  • natural capital unprocessed
  • lower GDP and poverty rates
  • Large population sector with low standard of living
  • High population growth rates

Sustainable Yield in Deserts

Sustainability a wide spread term in the last decades. Economists, politicians, scientists and  businessmen are using it for everything. It is really a fashion nowadays. We must understand its real value and its real importance. A sustainable development is needed if we want to maintain the equilibrium of the world, respecting its carrying capacity. 
Sustainable yield is the the natural income that can be exploited each year without getting rid of the resources. Sustainable yield is different from one ecosystem to another. We’ll work with sustainable yield in deserts.
Specifications.
We must considered that resources in desert biomes are very scarce. The levels of precipitation are less than 15 cm a year. The diversity of desert’s flora is relatively low compared to other biomes. Contrary to the common belief the actual fauna of deserts is very rich and its concentrated in certain areas. The resources of deserts around the world differ from one and other. We can find oil and other fossil fuels in some deserts, minerals, and species richness.
In order to measure, and thus manage sustainable yield, we must establish space and time parameters. This will help us to know how much we have and how much we can use.
Useful indicators had been developed in order to maintain track of the advances in sustainable development. Some examples of this indicators can be found here, the Finland's sustainable development indicators:
  • Human Development Index
  • Greenhouse gas emissions
  • Total energy consumption
  • Use of renewable energy sources
  • Energy and natural resource consumption in relation to economic growth
  • Environmental loading in ration to economic growth
It is important to notice that not just because we are respecting the maximum sustainable yield (MSY) of a certain system, the resources will be endless. There are a lot of variations and factors that affect a system. A pretty good example of this is the chaotic situation of West Coast groundfish fishery in the United States, explained deeply here.
This is another thing in which indicators come handy and it’s the point where the management enters into the picture.

Defining Sustainability

In simple words: sustainability is to endure. To exist for a long period of time. If you ask me, sustainability is “the responsible manage of resources that work towards using them while maintaining an equilibrium.”

Introduced in an actual context.
Sustainability is a term that has gained importance in the social world’s context because the arise of concern about the actual Eath’s natural capacity to sustain human life as it is know. That’s why the concept, in means of development, has been defined as: “sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

As a social issue, sustainability enters in means of maintaining the resources for future generation. We must understand that for the world natural equilibrium to be maintained, we need to start taking greater conscience about damage we are making to the environment and how we are wearing down its sustainability. That’s why society and specific institutions are working to create policies for the regulation of the human activities that act against sustainability.

In an economic context. The concept of sustainable yield enters into the picture. It is the increase of natural capital. The natural income that can be exploited each year without getting rid of it. MSY (maximum sustainable yield) is based on this last idea.

It’s equal to
-(The total biomass or energy at a time) T1 – (total biomass of energy at a time) T
-Annual growth and recruitment – annual death and emigration.

A few points to achieving a sustainable way of living:
  • To control the exploitation of natural resources.
  • To look for alternative practices that help prevent a loss of equilibrium.
  • Understand the entire human society structure and the economic system as part of the global environmental system
Sustainability is involved in three different spheres. Each one of the spheres functions as an individual particle, but at the same time are affected by the others.
