Updates on nature, land and biodiversity

Nature is humanity’s lifeline. Human health, food, economies and well-being depend on nature. Yet nature is in crisis. One million of the world’s estimated 8 million species of plants and animals are threatened with extinction. Meanwhile, ecosystem degradation is affecting the well-being of 40 per cent of the global population.

The spotlight on nature and biodiversity highlights updates from around the UN System, from partners and others, helping to call attention to the need for a just, prosperous and sustainable future for all.

New study defines conditions for successful long-term biodiversity net gain

A new study identifying the ecological conditions needed for biodiversity offsetting to achieve conservation goals could provide important guidance for governments and industries as they expand biodiversity net gain (BNG) and nature restoration policies. The research is published in the journal Conservation Biology.

Biodiversity offsetting is increasingly used to compensate for environmental damage caused by development. It sees habitat loss in one location compensated through habitat restoration or protection elsewhere, with the aim of achieving no net loss of biodiversity.

The latest research, led by Swansea University in collaboration with the UK Centre for Ecology & Hydrology (UKCEH) and Forest Research, shows that biodiversity offsets are far more likely to succeed when restoration areas are larger than impacted habitats, are protected over long timescales and are designed around how ecosystems recover over time.

Beyond lithium: how sodiumion batteries could change the world

The lithium-ion battery is the beating heart of the modern world. It powers eight billion mobile phones, hundreds of millions of laptops and rapidly growing fleets of electric cars and energy-storage banks. But there’s a new contender breaking into the battery market.

Batteries based on sodium promise to be cheaper, safer and much more environmentally friendly than lithium-ion cells. And this year could mark the start of the sodium era.

In April, Chinese firm CATL — the world’s largest battery producer — announced that it will start mass-producing sodium-ion batteries before the end of 2026. CATL, which is headquartered in Ningde, added that it had signed deals to sell the batteries both to a car manufacturer and to a provider of energy-storage stations for electricity grids.

New contact material improves efficiency and stability of perovskite solar cells

A newly developed material for the electron contact improves the efficiency of single perovskite solar cells and perovskite/silicon tandem solar cells. The new material is based on a carborane molecule. It offers several advantages over the standard material C60, as shown by the study led by Steve Albrecht’s team. The new material has since been patented and is already commercially available.

Perovskite solar cells are not only exceptionally inexpensive to manufacture but also achieve high efficiency levels. Single-junction perovskite devices can already convert more than 27% of sunlight into electrical energy, while perovskite-silicon tandem cells have achieved efficiencies of more than 35%. Until now, a layer of so-called “football molecules” (C60) has been used to transport electrons away. However, a significant proportion of the charge carriers are lost at the interface between the C60 layer and the perovskite absorber. Furthermore, C60 materials are relatively expensive and tend to delaminate over time, compromising the cell’s stability.

Plasma agriculture makes strides toward super-seeding conventional methods

Occasionally, the sun unleashes powerful flares and coronal mass ejections, which hurl plasma and energetic particles into space. On the infant Earth, this solar activity drove cascades of atmospheric chemical reactions that may have helped form the building blocks of life. More recently, scientists have discovered that applying plasma to seeds in a controlled way can trigger similar activity, making them faster-growing and more resilient. Researchers at Nagoya University and Kyushu University in Japan have compiled a comprehensive review of this new field—termed “plasma agriculture”—as a potential sustainable solution to address global food shortages.

The word plasma brings to mind a hot, ionized inferno that makes up the fourth state of matter. But the plasma used here is different. By applying high voltage to air or any gas, electrons are stripped from a tiny fraction of its molecules and gain very high energies. These electrons zipping around can effectively mimic the behavior of plasma even though the bulk of the gas remains at room temperature.

This low-temperature plasma can be applied directly to seeds without burning them. Excessive use of chemicals and genetic modification of plants cause concern for many people. Instead, plasma agriculture can offer similarly high crop yields without invasive intervention.

Bloomberg Donates $260 Million to Ensure New High Seas Treaty Translates to Lasting Ocean Protections

Bloomberg Philanthropies has identified a funding shortfall in the implementation of many countries’ ocean protection plans, and has attempted to fill it with a quarter-billion dollar donation.

The aim writ small is to translate the paper gains for ocean conservation and management secured with the passage of the UN’s new High Seas Treaty into real gains by helping to cover the cost of management and enforcement for small island nations that lack these resources.

The updated High Seas Treaty has been under negotiation for over 2 decades. Its passage secured major gains for the potential protection of critical ocean habitats.

Secure glass containers for storing chemical waste through laser welding

As the adoption of electric vehicles continues to grow, so does the need for the safe and permanent storage of battery materials and industrial chemical waste. Certain waste streams require disposal in what are known as Category IV landfills, which impose particularly stringent requirements on storage containers. These must simultaneously ensure environmental protection, safe handling and long-term structural integrity.

Glass is a highly promising material for this application: It is exceptionally chemically inert—meaning it reacts with virtually no other substances—making thick-walled glass containers especially well-suited for the permanent containment of hazardous materials. Glass containers are also of particular interest in the context of potential new recycling methods in the future. The stored residual materials do not react with the containers and can be readily recovered from them.

Until now, these glass containers have been manufactured primarily using thermal gas processes. However, these are limited by uncontrolled heat input, high residual stresses and restricted automation potential. Laser welding, on the other hand, enables high processing speeds and shows excellent potential for automation.

Rust-to-iron cycle may unlock long-term storage for renewable energy

In the future, iron might be used as a chemical energy storage material, making large quantities of renewable energy available in the long term. Iron powder is combusted in a cyclic process that is carbon neutral and then reconverted to its original state using energy input. Scientists at Karlsruhe Institute of Technology (KIT) were the first to conduct an extensive study to evaluate the potential of this technology for power generation. Their results show that iron, while not superseding hydrogen, may usefully complement it in a climate-neutral energy system. The findings have been published in Chem Circularity.

Be it for wind energy from coastal regions or for solar power from desert areas, iron could serve as a transportable energy carrier in the future to make these renewable energy sources usable worldwide. “This works in a cycle that emits no carbon dioxide or environmentally harmful substances,” said Julia Schuler from KIT’s Institute for Industrial Production (IIP). For power generation, iron powder is combusted, producing iron oxide, i.e. rust. Using hydrogen from renewable sources, it is reduced to iron again in a process that removes the oxygen it contains. The iron powder can then be reused.

“When burned, iron powder behaves very much like coal. We wanted to find out whether it was possible to repurpose existing coal power plants to iron-firing,” said Schuler. She believes that modifications are primarily necessary in the heat generator; other components, such as the steam cycle, turbines, generator and power grid connection, could continue to be used.
