Improving Nature, Climate, and Health Simultaneously through a Unified Approach

Tree-planting projects help tackle the climate crisis, but they can also impact water supplies

The major environmental, social and economic crises facing the world today, including biodiversity, climate change, health, food, and water, are closely linked, and we must work together to tackle them. has many advantages. However, focusing on just one issue can exacerbate other crises.

This is the conclusion of a major report compiled by 165 researchers from 57 countries and approved by 147 governments over the past three years.

United Nations conventions on issues such as biodiversity and climate focus on these issues separately. “So what we will do now in this report, which has not been done before, is to combine all of these and make sure that looking at these crises individually is not only inefficient, but actually the real danger. “It's about showing what's involved,” he says. paula harrison He co-chaired the evaluation process for the report at the UK Center for Ecology and Hydrology. “Action is urgent, but unless we act in a way that takes these interdependencies into account, we will create new problems or exacerbate existing ones.”

Mr Harrison said the scientific studies assessed for this report provide strong evidence that there are a number of actionable actions that can have beneficial effects on all five areas simultaneously. . These include conserving and restoring mangrove forests, improving soil health and carbon content, creating early warning systems for all kinds of hazards, reducing the risk of disease spread from animals to humans, and universal health insurance. It includes international cooperation on technology related to the problem.

There is a trade-off. Actions that have broad benefits are not the same as actions that are the best solution to a particular problem, she says.

“What you can’t do is get the best value possible at the same time,” Harrison says. “While we cannot optimize food production without negatively impacting everything else, we can take a balanced approach that benefits all.”

Harrison gives the example of planting trees to remove carbon dioxide from the atmosphere. If the focus is solely on climate, the trees selected are likely to be fast-growing non-native species that do not support wildlife and affect water supplies by taking up too much water. However, if a project takes a more holistic approach, it may choose native tree species that use less water and increase biodiversity. “It may not sequester as much carbon, but it will add a lot of value to other aspects of the system,” Harrison says.

There are also economic benefits to integrated approaches that help conserve biodiversity and achieve other goals. nexus reportMore than half of the world's gross domestic product ($50 trillion), as it is officially known, states that it is moderately to highly dependent on nature.

“The unaccounted costs of our current approach to economic activity, including climate change impacts on biodiversity, water, health, and food production, are estimated to be at least $10 trillion to $25 trillion per year. It has been.” Pamela McElwee The other co-chair, a professor at Rutgers University in New Jersey, said in a statement.

“There is a lot of evidence that there are very strong and growing biophysical risks to economic prosperity and financial stability if we continue the way we are,” Harrison said.

The Nexus report was compiled by: Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)which is a non-UN body, but functions in a similar way to the Intergovernmental Panel on Climate Change. The report was formally approved by representatives of the 147 IPBES member countries who met in Namibia on 16 December.

says the report is very ambitious Anne LarigoderlyExecutive Director of IPBES. Its purpose is to provide the science and evidence needed to support the achievement of other international conventions, such as the United Nations Sustainable Development Goals, the Kunming-Montreal Global Biodiversity Framework, and the Paris Agreement on climate change. , she says.

Groundbreaking Discovery in Quantum Gravity May Lead to a Unified “Theory of Everything”

Curious about what goes on inside a black hole? Wondering about the origins of the Big Bang and how the forces of the universe came together? These are some of the biggest questions humanity has about the universe, and new discoveries are bringing us closer to the answers than ever before.

Scientists have made a breakthrough in measuring gravity in the quantum world, with British, Dutch, and Italian teams utilizing new technology to detect weak gravity on small particles. By suspending particles weighing just 0.43 mg at ultra-low temperatures, they were able to isolate the vibrations of the particles using magnets and superconducting devices.

This groundbreaking technique allowed scientists to measure weak attractive forces of only 30 attonewtons (aN), a force smaller than that of a bacterium on a table’s surface. Previously, understanding how gravity worked at the microscopic level had eluded scientists, but this discovery has shed light on the interaction of forces with particles at a small scale.

Lead author of the study, Tim Hooks from the University of Southampton, noted that scientists have been struggling for a century to understand how gravity and quantum mechanics interact. This new discovery brings us closer to unraveling the mysteries of the universe and potentially paves the way for further advancements in measuring quantum gravity.

By continuing to refine the method used in this study, researchers hope to delve deeper into the forces that govern the universe, ultimately leading to a better understanding of the very structure of our cosmos.

“We are on the brink of new discoveries about gravity and the quantum world,” said Professor Hendrik Ulbricht, one of the study authors.
