Resilience index needed to keep us within planet’s ‘safe operating space’

We need to shift focus from GDP towards more holistic measures, say researchers

2024-11-15
(Press-News.org) EMBARGOED: NOT FOR RELEASE UNTIL FRIDAY 15 NOVEMBER 2024 AT 11:00 ET (15:00 UK TIME).

Researchers are calling for a ‘resilience index’ to be used as an indicator of policy success instead of the current focus on GDP.

They say that GDP ignores the wider implications of development and provides no information on our ability to live within our planet’s ‘safe operating space’.

In a paper published today [15 November] in the journal One Earth, researchers from the University of Southampton, UCL and the University of East Anglia outline the case for using a resilience index to inform policy decisions, arguing it would be a much more appropriate measure for the modern age than GDP.

“Resilience is about the ability of a system to prepare for, resist, recover and adapt to disturbances in order to function successfully,” says Professor Ian Townend, lead author of the paper from the University of Southampton.

“This invites us to take a more holistic view, accommodating both human and natural components of complex systems that extend across environmental, social and economic domains.”

Gross Domestic Product (GDP) was adopted to guide progress when the Great Depression of the 1930’s led to a need for economic growth. Since then, it has become one of the most significant policy indicators.

But there is increasing concern about our use of resources on a finite planet and the growing and interacting pressures of pollution, biodiversity loss and climate change.

That’s prompted scientists to consider a ‘safe operating space’ that ensures humanity has an adequate social foundation, while remaining within sustainable ecological limits (also known as planetary boundaries).

“As we encroach on planetary boundaries, the number of organisms an ecosystem can support is reduced,” says Prof Townend. “Similarly, if we don’t address inequality, embark on conflict, or suffer major disasters, our social foundations are diminished.”

The researchers believe that a resilience index can help policy makers to steer a course through this safe operating space.

Professor Jon French, a coauthor on the paper from UCL, says: “Often what we can measure is what gets done, so it’s important to provide a quantitative measure of resilience at local, national and global scales.

“Necessarily, such a measure will incorporate value judgements. Rather than seeing this as a drawback, this can allow differing views within a society to be captured.

“It also helps decision makers to consider the inherent trade-offs when dealing with systems that extend across social, environment and economic domains.”

In the paper, the researchers provide two examples of how a resilience index might be used at a national and global scale.  

The University of Southampton has developed a model to index the resilience of England’s coastal communities. The model allows decision makers to adjust the relative weight given to different priorities, such as human health, economic damage or habitat loss.

This means stakeholders, such as local government, businesses, or communities, can influence how resilience is quantified based on their specific needs, ensuring decisions reflect a balanced view of competing interests​.

The team applied a similar method on a global scale using existing data sets. They mapped biophysical and social performance measures to index the resilience of 132 countries during 1992 and 2015.

In this illustrative example, the global index revealed a trend towards progress being made on social measures at the expense of biophysical measures of resilience.

The team believe such models could enhance or even replace traditional performance measures, but suggest further development is needed.

“We urgently need to think about how we mobilise a global change in outlook,” says Professor Robert Nicholls, another coauthor on the paper from the Tyndall Centre for Climate Change Research at the University of East Anglia.

“That means moving away from the focus on GDP to measures that track the challenges we face to meet societal needs and recognise that these are inextricably linked to the needs of all life on earth.”

The paper Framing resilience to manage complex environmental systems is published in One Earth and is available online.

The work was supported by the UK Climate Resilience Programme through UK Research and Innovation (UKRI).

How stress is fundamentally changing our memories

2024-11-15
Researchers at The Hospital for Sick Children (SickKids) have uncovered that stress changes how our brain encodes and retrieves aversive memories, and discovered a promising new way to restore appropriate memory specificity in people with post-traumatic stress disorder (PTSD).   If you stumble during a presentation, you might feel stressed the next time you have to present because your brain associates your next presentation with that one poor and aversive experience. This type of stress is tied to one memory. But stress from traumatic events ...

A team of researchers from McGill and Université de Montréal’s Observatoire pour l’éducation et la santé des enfants (OPES, or observatory on children’s health and eduation), led by Sylvana Côté, found that spending two hours a week of class time in a natural environment can reduce emotional distress among 10- to 12-year-olds who had the most significant mental health problems before the program began. The research comes on the heels of the publication of a UNICEF ...

In vitro model enables study of age-specific responses to COVID mRNA vaccines

2024-11-15
mRNA vaccines saved lives during the COVID-19 pandemic, but older people had less of an immune response to the vaccines than did younger adults. Why? Boston Children’s researchers, led by Byron Brook, PhD, and Ofer Levy, MD, PhD, have found some answers, while providing proof-of-concept of a new system that can model vaccine responses in a dish. The test system, described in a paper out today in iScience, is called MEMPHIS (Modular Evaluation of immunogenicity using Multi-Platform Human In vitro Systems). It analyzes whole human blood from people of different age groups and applies both proteomics and targeted assays to measure ...

Sitting too long can harm heart health, even for active people

More time spent sitting, reclining or lying down during the day may increase the risk of cardiovascular disease (CVD) and death, according to a study in JACC, the flagship journal of the American College of Cardiology, and presented at the American Heart Association’s Scientific Sessions 2024. More than roughly 10-and-a-half hours of sedentary behavior per day was significantly linked with future heart failure (HF) and cardiovascular (CV) death, even among people meeting recommended levels of exercise. “Our findings support cutting back on sedentary time to reduce cardiovascular risk, with 10.6 hours a day marking a potentially key threshold ...

One or many? Exploring the population groups of the largest animal on Earth

2024-11-15
FROM: James Urton University of Washington 206-543-2580 jurton@uw.edu   (Note: researcher contact information at the end)   Hunted nearly to extinction during 20th century whaling, the Antarctic blue whale, the world’s largest animal, went from a population size of roughly 200,000 to little more than 300. The most recent estimate in 2004 put Antarctic blue whales at less than 1% of their pre-whaling levels. But is this population recovering? Is there just one population of Antarctic blue whales, or multiple? Do these questions matter for conservation? A team led by Zoe Rand, a University of Washington doctoral student, tackles these questions ...
