Planetary boundaries and population

Planetary boundaries and population

We live in the Anthropocene era, in which humans are the single largest modifier of planet Earth.

The consequences of there being seven billion of us on the planet are more than the Earth’s natural biophysical and geological systems can process.

The concept of ‘planetary boundaries’ is one of defining a ‘safe operating space’ for human societies to develop and thrive, based on the functioning and resilience of the Earth.

Based on the human-induced alterations in the natural environment, nine planetary boundaries have been identified, each with defined threshold limits. Crossing these boundaries will result in deleterious consequences for all species on Earth, and damage the possibility of achieving a sustainable future.

In this briefing, we explore the approach, concept and limits of planetary boundaries, and discuss the influence of population growth on these boundaries.

The nine planetary boundaries are based on three scientific principles:

  • the level of usage of non-renewable fossil resources
  • the level of usage of the biosphere, and exploitation of natural ecosystems
  • the level of Earth’s capacity to absorb and dissipate human waste flows

Climate change and the integrity of the biosphere are the two most important limits, because they influence the threshold limits of the remaining boundaries.

According to recent estimates, we have already crossed four of the nine planetary boundaries, highlighting the current scale of human-induced alterations in the environment.

If these changes are not reversed, and if the current scale of depletion of natural resources continues, we will jeopardise our future by driving innumerable species to extinction.

Stabilising population growth is essential to avoid crossing the limits of the nine planetary boundariesPopulation Matters asserts that stabilising population growth is essential if we are to avoid crossing the defined threshold limits of the nine planetary boundaries.

The concept of Planetary Boundaries is thus an effective tool to aid decision-makers by defining the safe operating space for humanity and a sustainable future.

New ‘Sustainability Insights’ collection

We have recently updated our set of intermediate-level papers on issues related to population and sustainability.

Insights into population sustainability issuesOur new and improved collection of ‘Sustainability Insights’ papers appears in the ‘Resources’ section of our website, providing more information than our introductory section, ‘The Issue’, whilst still being accessible to readers who do not yet possess a detailed knowledge of the topics.

The index page of our Sustainability Insights collection is linked from the Resources menu on our home page, at www.populationmatters.org/resources/sustainability-insights, in order to help readers understand how the various pieces of the population sustainability jigsaw fit together.

We hope this will also encourage dialogue between experts in the various subjects involved.

Population and resource security

Population growth and increasing affluence will increase the pressure on limited resourcesWater scarcity, energy challenges and food security are three increasingly-recognized global challenges. Resource security, however, remains largely unaddressed, in part because the majority of minerals and metals are not currently scarce and the importance of these resources is not as obviously visible.

Projected population growth and increasing affluence will, however, cause demand for resources to grow. This will cause greater competition, which means that those countries largely dependent on imports for their resources, such as the UK, may end up in a particularly vulnerable position.

This briefing will look at resource demand, security and scarcity. It will be argued that, while there are many ways in which resource security can be improved in theory, these are often not viable.

One reason is that different challenges have conflicting solutions. Land could be used to extract minerals and metals, but the same land could also be used by farmers to increase output, or by the building sector to develop residential properties.

At the same time, there are conflicting scarcity problems that appear more urgent than impending metal and mineral scarcity. Water scarcity will be a serious problem, and the increasing demand for energy will difficult to meet.

The challenge can only be solved by reducing demand for resources of all kindsWhen considering widely discussed solutions for these global challenges, it becomes obvious that much trust is placed in technology. Technology, however, relies heavily on the availability of metals and minerals, and all of these solutions would consequently influence resource security adversely.

What this shows, more than anything, is that the complicated and intertwined nature of the challenges the world faces can in the long term only be solved by actively reducing demand for resources of all kinds.

This means that we ought to reduce per capita demand, but more importantly, that population stabilisation policies are of paramount importance. This is particularly the case given the currently very low per capita consumption of much of the world’s population.

Population and Ethics colloquium

‘Population and Ethics: Interdisciplinary Perspectives on Birth and Death’

Cumberland Lodge, Monday, 26 September 2016 — 9:00am to 9:00pm

Undoubtedly, many of the most pressing challenges of our age relate to changes in human population.

Yet these questions receive little attention from academics, and public debate is often led by unconsidered opinion and ideological divides about the ethics of birth and death.

Many of the most pressing challenges of our age relate to changes in human populationThis presents opportunities for interdisciplinary researchers to break new ground and make significant contributions to contemporary policy decisions.

A one-day colloquium taking place at Cumberland Lodge in Windsor, UK, this September will bring together scholars who can combine ethical analysis and scientific rigour to address these challenges head on, and to forge new lines of academic inquiry.

Researchers from philosophy and the social sciences, as well as practitioners and policy makers, will share their knowledge and concerns, learn from one another, and forge collaborative relationships.

This will not simply be a conference for the paper givers, but an opportunity for open and honest debate of challenging issues and fundamental questions.

Key themes of the colloquium will include:

  • The morality of birth: why do people decide to have children, and what role can, and should, morality play in such decisions?
  • The changing shape of society: how are large-scale demographic changes, such as growing life expectancy and shrinking family sizes, changing the dynamics of our lives, and how should society respond to this?
  • Human populations and the environment: how do growing human populations interact with other species and what challenges does this raise for our planet?
  • Optimum demographics: what role does population play in economic and social development, and is there such a thing as an optimum population?
Professor Sir Partha Dasgupta
Professor Sir Partha Dasgupta

The colloquium will close with a keynote public lecture entitled ‘Population Ethics and Earth’s Carrying Capacity’, from Population Matters patron Professor Sir Partha Dasgupta, Emeritus Professor, Frank Ramsey Professor Emeritus of Economics at the University of Cambridge.

Day attendance at the colloquium is free, and prospective attendees can register online at www.eventbrite.co.uk. Overnight accommodation can be arranged at extra cost, if required.

Population growth hinders Sustainable Development Goals

london_crowd copyWhile the fact that the UK played a leading role in the formulation of the 17 UN Sustainable Development Goals (SDGs) is welcome, the UK Government has done little to establish how to implement the Goals since they came into force on 1 January 2016.

On 8 June, the International Development Committee (IDC) launched its report on the UK implementation of the SDGs.

Following this, the Environmental Audit Committee has launched an inquiry into their domestic implementation.

Our submission to this inquiry aims to draw attention to the fact that, regardless of which route is chosen to implement all SDGs successfully by 2030, population growth will make achieving this goal more difficult and more expensive.

The reason for this is simple: the SDGs must be delivered for each individual in society. The more people there are, the more will have to happen to achieve that.

The UK already faces serious population-related challenges, and these cannot be ignored.

Many challenges — housing scarcity, strain on education and health care facilities, and child poverty, for example — must be overcome in order to call the implementation of the SDGs a success. Yet, population growth will exacerbate these challenges.

Consequently, we believe that population growth should no longer be approached as a fixed premise.

This means that the Government should start promoting policies that aim at population stabilisation.

WINGS for a better life

Like many 21-year-old women in Guatemala, Fabiola was unaware of the existence and possibilities of birth control. Consequently, she had given birth to her first child at the tender age of 18.

A second child had followed a year later, and not long thereafter a third had been added to the family.

While Fabiola loves motherhood and her children, she is worried about the future.

“I can’t afford to provide my children with everything I’d like to give them, and when they get sick, I can’t sleep because I’m worried about their well-being.”

Having grown up in a family of seven children, Fabiola always had to help her mother to keep the household running. She was in charge of the house and took care of her siblings, even though she was a child herself at the time.

Despite a strong fear that her community would judge her for using birth control, Fabiola knew that she did not want a similar future for her sons.

WINGS, an organisation supported by Population Matters’ initiative ‘PopOffsets’, encourages women to use long-acting reversible contraceptives. They were there for Fabiola when she needed help and guidance in choosing the right anticonception method for her and her family.

After discussing all the options available to her, Fabiola picked a subdermal hormonal implant that will give her five years of protection.

Grateful for the support, she noted that she can now dedicate her time to raising her children without having to worry about extra mouths to feed. As she does not have enough money to pay for the implant, the project managed to help her free of charge.

We are delighted to see that funding of small-scale family planning projects has the power to transform lives for the better. What seems like a small change for some, is a huge step for others.

PopOffsets helps to support the work of WINGS and many other similar initiativesCurrently, more than 225 million women worldwide wish to avoid pregnancy but are not using modern family planning methods. Initiatives like PopOffsets can do much to reduce that number.

This is why we invite you to visit the project’s web-page, and to consider supporting it.

Population growth drives migration

Sometimes a person has no choice but to leave home and seek a more bearable life elsewhereMigration is a global phenomenon of increasing scale and concern, and is addressed in our latest briefing.

The ongoing “migration crisis” in the European Union and the United Kingdom has affected every corner of society, raising a number of uncomfortable issues.

Migration is defined as the movement of people that involves change of residence from one place to another and impacts the structure, composition and growth of a country. About one in seven people worldwide are identified as international or internal migrants, a record level.

People leave their home for diverse reasons, and sometimes have little choice — for example, as a consequence of disease, conflict or natural disasters. These are, in turn, a result of pressure on the environment from high human population growth or density, and from overconsumption of natural resources, leading to poverty and low living standards.

To alleviate poverty and improve people’s living standards, which will in turn reduce migratory pressure, Population Matters promotes moderating population growth.

Population Matters believes that improving living standards through limiting population growth will enhance opportunities for every individual.
