Researchers in the United States have developed a new aluminium-based chemical recycling process that converts plastic waste into fuel-range hydrocarbons at significantly lower temperatures than conventional recycling methods, potentially offering a more energy-efficient approach to managing global plastic pollution.

The technology, developed by scientists at Oak Ridge National Laboratory, uses a molten salt solution containing aluminium chloride to break down polyethylene, one of the world’s most widely used plastics, into liquid hydrocarbons suitable for fuel applications.

The research represents part of a broader global effort to improve chemical recycling technologies as governments and industries face increasing pressure to reduce plastic waste entering landfills, incinerators and natural ecosystems.

According to details released by the research team, the molten aluminium salt serves both as the reaction medium and as the active chemical agent, removing the need for additional catalysts, hydrogen inputs or organic solvents commonly used in other plastic-to-fuel conversion systems.

The process operates at temperatures below 200 degrees Celsius, substantially lower than traditional pyrolysis-based recycling technologies that typically require temperatures between 450 and 500 degrees Celsius. Researchers said the lower operating temperature could reduce energy consumption and improve the economic feasibility of large-scale deployment.

Approximately 60% of the resulting output consists of hydrocarbons within the gasoline fuel range, according to the study. These products could potentially be used in transportation fuels or industrial chemical applications following further processing and refinement.

Polyethylene, the target material used in the experiment, is among the most common plastics globally and is widely used in packaging films, shopping bags, containers and consumer products. Its widespread use has made it a major contributor to global plastic waste streams.

Chemical recycling technologies such as the molten-salt approach differ from conventional mechanical recycling systems, which typically involve sorting, cleaning and remelting plastics for reuse. Mechanical recycling often faces limitations because repeated processing can degrade material quality and because many mixed or contaminated plastics cannot be efficiently recycled through conventional systems.

The Oak Ridge process instead breaks polymer chains into smaller hydrocarbon molecules, transforming waste plastics into chemical feedstocks or fuel products rather than reproducing new plastic material directly.Researchers used neutron scattering and spectroscopy techniques to observe how polymer chains decomposed during the reaction process.

According to the study, these analytical methods helped scientists better understand the chemical mechanisms involved and optimise the breakdown process.The aluminium chloride molten salt system also avoids dependence on expensive catalysts frequently used in advanced chemical recycling systems.

Many competing technologies rely on rare or precious metals to accelerate polymer decomposition, increasing operational costs and creating additional supply-chain constraints.Industry analysts say reducing catalyst requirements could improve scalability if the process proves commercially viable at industrial scale.However, researchers acknowledged that several technical challenges remain before the technology can move toward widespread commercial adoption.

One of the principal obstacles involves the moisture sensitivity of the molten salt mixture. Exposure to water can interfere with reaction efficiency and alter the behaviour of the chemical system, creating operational difficulties for industrial facilities.

The report noted that further work is needed to improve long-term system durability, process stability and industrial safety before large-scale commercialisation becomes practical.Plastic waste remains one of the fastest-growing environmental challenges worldwide.

According to estimates from international environmental agencies, hundreds of millions of tonnes of plastic waste are generated annually, while recycling rates remain comparatively low across many regions.Most plastic recycling today relies on mechanical systems that can only process limited categories of plastic waste efficiently.

Complex, contaminated or multi-layered plastics often remain difficult to recycle economically and frequently end up in landfills or are incinerated.Advanced recycling technologies, including pyrolysis, solvent-based recovery and catalytic depolymerisation, have gained increased investment attention in recent years as policymakers and manufacturers seek alternatives capable of handling mixed plastic waste streams.

Supporters of chemical recycling argue that these technologies could contribute to a more circular plastics economy by treating plastic waste as an industrial feedstock rather than disposable refuse. Critics, however, have questioned whether some plastic-to-fuel systems merely shift environmental impacts from waste management to fuel combustion emissions.

The Oak Ridge aluminium-salt process enters this broader debate at a time when industries are facing mounting regulatory pressure to improve waste recovery rates and reduce environmental pollution associated with plastics.The findings also highlight the growing intersection between the aluminium sector and sustainability-focused industrial technologies.

Aluminium compounds such as aluminium chloride are increasingly being studied for roles in catalysis, energy storage and chemical processing because of their thermal and reactive properties.

Researchers involved in the project said continued development will focus on improving efficiency, reducing operational sensitivities and evaluating the economic viability of scaling the process for industrial use.

Brazilian Indigenous leader, writer and environmental thinker Ailton Krenak has spent decades challenging dominant political and economic assumptions in Brazil, arguing that modern consumer-driven society has severed humanity’s relationship with nature while deepening social inequality and ecological destruction.

Nearly four decades after a landmark appearance before Brazil’s constitutional assembly helped secure Indigenous rights protections in the country’s democratic constitution, Krenak has emerged as one of the country’s most influential public intellectuals, combining environmental criticism, Indigenous cosmology and political activism in lectures and bestselling books translated into more than 13 languages.

Krenak, 72, first gained national prominence in 1987 during the drafting of Brazil’s post-dictatorship constitution. Addressing lawmakers in Brasília while wearing a suit and tie, he slowly covered his face with black jenipapo dye, traditionally used in Indigenous body painting, as he condemned centuries of violence against Indigenous communities.“Indigenous blood has been spilt over every hectare of Brazil’s 8m square kilometres,” he told legislators at the time.

The gesture became one of the defining images of Brazil’s democratic transition and contributed to the inclusion of constitutional protections recognising Indigenous peoples’ rights to their traditional lands, social organisation and cultural identity under the 1988 constitution.Reflecting on the speech nearly 40 years later, Krenak described congress as a place where political power was concentrated through language and public speech.

“There, the young Ailton understood the meaning of parliament,” he said. “The place to speak, the power of the word.”In 2024, Krenak entered another historically exclusive institution when he became the first Indigenous Brazilian elected to the Brazilian Academy of Letters, an organisation founded in the 19th century and traditionally dominated by white intellectual elites.

At his inauguration ceremony, Krenak used the occasion to highlight Brazil’s Indigenous diversity, invoking dozens of Indigenous peoples while wearing the academy’s formal embroidered uniform alongside Indigenous adornments.“I am only one, but I can invoke 305 peoples,” he said.Krenak’s growing international influence has been driven largely by a series of books focused on environmental degradation, capitalism and the relationship between humanity and the natural world.

His 2020 book Ideas to Postpone the End of the World became a major commercial and intellectual success in Brazil and abroad, later followed by Life Is Not Useful and Ancestral Future.Across his writing and public lectures, Krenak argues that modern societies have normalised environmental destruction through economic systems centered on consumption and extraction.

“We are treading heavily on the Earth,” he said during a recent lecture in Rio de Janeiro. “Modernity is very active in making us consumers but leaves little time and space to coexist.”Krenak frequently frames environmental collapse not only as a scientific or political issue but also as a cultural and spiritual crisis. He criticises what he describes as a model of development that treats nature exclusively as a resource for economic growth.

“Development is not an innocent word,” he said. “It fires a shot at someone.”Despite the severity of his message, Krenak often delivers lectures with humour and conversational ease. During one recent appearance, he abruptly interrupted his own discussion of social exclusion and environmental decline by joking that the audience had “fallen into a trap” after expecting a more uplifting talk about dreams and creativity.

Friends and observers frequently describe his public speaking style as calm and accessible despite the radical nature of many of his arguments.Born in 1953 in Minas Gerais state, Krenak belongs to the Krenak people, whose ancestral territory lies along the Doce River in southeastern Brazil.

He recalls spending his childhood surrounded by forests, rivers and open land before military-era land seizures displaced his community.During Brazil’s military dictatorship, authorities fragmented Krenak territory and redistributed land titles to farmers, forcing Indigenous families to flee repeatedly.“It’s a bodily experience of being in a world with no risks,” Krenak said of his early childhood.

“Then suddenly you are warned by adults that you must run away.”His family eventually fled through several regions of Brazil, at times living along highways while searching for safety.“I remember the feeling of being on the run, of not knowing if we’d find a safe place to sleep,” he said.

Krenak has often linked those experiences of displacement to broader historical patterns affecting Indigenous communities and diasporic populations. He argues that Brazilian society lacks a shared historical memory because different groups experienced the country’s development through profoundly unequal realities.

“We are not equal,” he said. “We don’t have a shared memory of history in Brazil.”After relocating to São Paulo and Paraná, Krenak became involved in organising Indigenous political movements and media initiatives. He helped establish an Indigenous newspaper at São Paulo’s Pontifical Catholic University, later transforming it into audio bulletins distributed to Indigenous villages on cassette tapes and eventually into a radio programme.

In 1980, he co-founded the Union of Indigenous Nations, which became a major voice in Brazil’s Indigenous rights movement during the democratic transition.Krenak’s environmental advocacy was further shaped by the 2015 Mariana mining disaster, one of Brazil’s worst environmental catastrophes.

The collapse of a tailings dam owned by mining companies Vale and BHP Billiton destroyed villages and released toxic waste across hundreds of miles of the Doce River basin.For the Krenak people, the river is regarded as a sacred ancestor known as Watu.Ten years after the disaster, Krenak said the river remains deeply damaged.“To declare it dead would be giving up,” he said, describing the river instead as being “in a coma”.

Krenak continues to argue that Indigenous knowledge systems offer alternatives to economic models based solely on extraction and consumption.

He says modern societies must reconsider assumptions about progress, ownership and humanity’s place within nature.“If I can imagine a utopia,” he said, “it is for humans to recover the experience of a simple life.”

In the densely populated informal settlements of Mumbai, a local waste-for-food initiative led by 27-year-old social entrepreneur Shakti Yadav is combining environmental cleanup efforts with food distribution in communities affected by poor sanitation and limited access to nutrition.

Yadav, founder of the “Buy Food with Plastic” initiative, operates a system in which residents exchange discarded plastic bottles for prepared meals. According to the programme’s operating model, 20 plastic bottles are accepted in return for one hot meal.The initiative, launched in 2020, has so far distributed more than 42,000 meals, supported approximately 4,500 people and conducted sustainability awareness activities involving over 1,000 students, according to figures cited in the report.

Yadav said the project was shaped by his own experience growing up in a Mumbai slum, where seasonal flooding and poor waste management created recurring public health risks.“During the monsoons, sewage water would flood the streets,” he said. “People had to wade through it because discarded plastic choked the drains.”

According to Yadav, blocked drainage systems contributed to repeated outbreaks of mosquito-borne diseases, including dengue and malaria, in vulnerable neighbourhoods. His initiative was designed to address what he described as two interconnected urban challenges: unmanaged plastic waste and food insecurity.The programme operates through a circular collection and redistribution model.

Plastic bottles collected from participating residents are transferred to recycling facilities, where some workers are recruited from the same communities supplying the waste. The recycled material is then repurposed into products including flowerpots and tea coasters, which are later sold to companies, including international corporations.

Mumbai, India’s financial capital and one of the country’s most densely populated cities, generates thousands of tonnes of municipal solid waste daily. Plastic waste management has remained a major challenge for urban authorities, particularly during monsoon periods when clogged drainage infrastructure increases flood risks in low-income settlements.

Yadav said the project was inspired by a similar initiative operating in the United States. He contacted the founder of that programme and developed his own local adaptation focused on conditions in Mumbai’s informal settlements.An MBA graduate and the first member of his family to pursue higher education, Yadav initially managed the project while working in a corporate job.

He later left full-time employment to focus entirely on expanding the initiative.The transition initially faced resistance within his family. According to the report, Yadav’s mother questioned the sustainability of non-profit work and believed such efforts were generally undertaken by financially secure individuals or organizations.Yadav said he eventually persuaded her by demonstrating how the programme could simultaneously reduce waste accumulation and improve food access in underserved communities.

The meals distributed through the initiative are intended to support residents in slum areas where access to affordable and nutritious food remains inconsistent. By linking food distribution with waste collection, the programme also attempts to incentivize recycling participation among residents who may otherwise lack formal waste disposal options.

Environmental awareness has become another component of the initiative’s outreach strategy. Yadav and his team regularly visit schools and residential communities to conduct educational sessions focused on sustainability and waste disposal practices.“Previously, nobody told me that throwing plastic away was harmful,” Yadav said, describing the lack of environmental education during his childhood.

The awareness campaigns target younger audiences in particular, with organizers seeking to promote behavioural changes related to littering, recycling and environmental responsibility.The initiative’s visibility has expanded beyond Mumbai in recent years. According to the report, Yadav represented India in Germany during a programme focused on sustainability and climate change research.

He was also awarded the 2023 Cross-Cultural Program Fellowship.The project currently operates in selected slum clusters across Mumbai, although Yadav said he intends to expand its reach across additional parts of the city.Urban policy experts have increasingly emphasized the relationship between waste management, flooding and public health risks in Indian metropolitan regions.

During annual monsoon periods, low-income settlements often experience disproportionate exposure to waterlogging and sanitation failures due to inadequate drainage systems and high concentrations of unmanaged waste.

Plastic waste has become a central issue in municipal governance discussions across India, particularly after several state governments introduced restrictions on single-use plastics and expanded recycling regulations in recent years. Enforcement and waste segregation, however, remain inconsistent across many urban districts.

Programmes such as “Buy Food with Plastic” operate outside formal municipal systems but increasingly form part of localized efforts aimed at combining environmental management with social welfare objectives.The initiative also reflects a growing trend among younger social entrepreneurs in India seeking hybrid solutions that combine recycling, employment generation and food distribution.

By connecting waste collection with direct community incentives, such models attempt to address both environmental and economic pressures simultaneously.Yadav said his long-term objective remains focused on improving conditions within communities similar to the one where he was raised.

“My goal is to eradicate both plastic waste and hunger,” he said.

Australia’s long-standing do-it-yourself culture is increasingly being reshaped by concerns over waste, emissions and the rising cost of replacing household equipment, prompting greater interest in electric tools, repair cafes and community-run tool libraries.For many Australians, weekend trips to hardware stores remain a routine part of home and garden maintenance.

Survey data shows about 57% of Australians consider themselves willing to undertake repairs and improvements around the house and garden. But environmental advocates and repair networks say the traditional DIY model, particularly one reliant on petrol-powered equipment and infrequently used new tools, carries significant environmental and financial costs.

Australia imports more than one million outdoor power tools annually, including lawnmowers, leaf blowers, hedge trimmers, chainsaws, chippers and pressure washers. Many of these are powered by two-stroke or four-stroke petrol engines, which generate noise, greenhouse gas emissions and exhaust pollutants including carbon monoxide, nitrogen oxides, volatile organic compounds and fine particulate matter.

According to the California Air Resources Board, operating a commercial leaf blower for one hour produces a similar level of air pollutants as driving a car for about 1,700 kilometres, roughly the distance between Melbourne and Brisbane.

One hour of lawn mowing produces emissions comparable to driving about 480 kilometres.Research has also shown that on summer weekends in Australia, small non-road engines, largely from lawn mowing and recreational boating, contribute up to 20% of certain forms of air pollution, including carbon monoxide and volatile organic compounds.

In California, these engines overtook passenger vehicles as the largest source of smog-forming pollution in 2020.Harry Barber, a transport consultant and volunteer with Electrify Yarra, said battery-electric alternatives are now available for nearly all common household garden tools, reducing the need for petrol-powered equipment.“Whether it’s a mower, or a blower, or a whipper-snipper, or a chainsaw. Whatever you need, it can all be electric,” Barber said.

He said transitioning to electric tools is significantly more affordable for most households than replacing a petrol vehicle with an electric car. Many manufacturers also design batteries that work across multiple tools, reducing both cost and material use.Barber said electric tools offer additional benefits beyond emissions reduction.

They are quieter, require less maintenance and eliminate the burnt oil smell associated with two-stroke engines. Although Australia banned the sale of two-stroke tools in 2020 due to pollution concerns, many households continue to use older equipment already in circulation.

In the United States, dozens of cities have banned the sale of petrol-powered leaf blowers or introduced financial incentives to encourage households and landscaping businesses to adopt electric alternatives.Alongside the shift toward electric equipment, another movement is growing across Australian cities: borrowing instead of buying.

Tool libraries, where residents pay a membership fee to borrow tools rather than purchase them, are expanding as communities seek to reduce overconsumption and make expensive equipment more accessible.

The “Heroes of Tomorrow: UN SDG Action Awards” is a global initiative recognizing efforts aligned with the UN SDG Action Campaign and the broader Sustainable Development Goals agenda.

The awards, launched as part of the SDG Global Festival of Action, highlight work across areas including climate action, gender equality, education and peacebuilding.

Marina Ponti, global director of the campaign, said the program aims to amplify voices from underserved communities leading transformative change. She described awardees as individuals who act decisively despite constraints and demonstrate commitment to building a more equitable and sustainable world.

Ponti said the 2026 edition will feature three categories: Changemaker, recognizing leadership in justice and peace; Creativity, focusing on initiatives using art and innovation; and Resilience, highlighting efforts addressing conflict, inequality and climate pressures.

Past awardees include Syrian refugee Jin Dawod, whose mental health platform supports displaced communities across 26 countries, and Julienne Lusenge, known for her work supporting survivors of gender-based violence and advancing peacebuilding in the Democratic Republic of Congo.

According to Ponti, the program has received around 5,500 applications from 190 countries in recent years, with entries assessed on impact, scalability and innovation, alongside what she described as a distinguishing “wow factor.”

She noted disparities in application volumes due to barriers such as language and access, with a higher share of submissions coming from English-speaking countries. The campaign is exploring measures to improve inclusivity through expanded outreach, language support and partnerships.

Ponti added that governments can strengthen participation by investing in local initiatives through funding, training and capacity-building programs to help scale grassroots solutions.

Finalists will be invited to an awards ceremony scheduled for later in the year.

A group of writers gathered on weathered couches in a sparse, plywood structure in the California desert recently, reading poetry and exchanging critiques in a setting that, at first glance, resembled a typical university workshop.

Laptops rested on knees, tea was poured into cups, and participants offered encouragement after each reading. But beyond the circle, the surroundings told a different story: a windswept, isolated landscape with no permanent infrastructure, far removed from any conventional campus.

The gathering took place at what participants call Mars College, an experimental learning community located near Bombay Beach, roughly 200 miles from Los Angeles and about 40 miles from the nearest grocery store. The site sits beside the Salton Sea, a shrinking and environmentally stressed body of water, and consists of temporary structures assembled from plywood and metal frames.

Co-founder Gene Kogan, a programmer and artist, said the name “Mars College” emerged informally, reflecting the stark terrain. “It kind of looks like Mars out here,” he said, describing the barren surroundings.The initiative operates outside the framework of traditional higher education.

There are no degrees, formal admissions, or accreditation systems. Tuition is not charged in the conventional sense, though participants contribute a few hundred dollars to cover shared costs such as internet access, food, and sanitation facilities. There are no permanent utilities; electricity is largely generated through solar panels, while water and waste management require transportation to and from the site.

Classes are organized daily and led by participants themselves, covering topics ranging from creative writing to solar panel installation and mathematical concepts. The structures hosting these activities are erected at the start of the program in January and dismantled by April, when the seasonal “semester” ends and participants leave.

Kogan said the project is not intended to replicate a university. “I’m not attached to the word college,” he said. “I’m not trying to convince anyone we’re a university of sorts.” He described it instead as an alternative model that responds to concerns about rising education costs and changing labor market conditions.

The concept emerged partly from experiences at large-scale gatherings such as Burning Man in Nevada, where temporary communities and structures are built and later dismantled. One of the project’s co-founders, who goes by Freeman, began constructing modular living spaces from industrial pallet racks at the festival. After acquiring a 20-acre plot of desert land in 2019 for approximately $20,000, he established a more setting for the experiment near Bombay Beach.

Kogan, who holds a mathematics degree from Columbia University and later received a Fulbright scholarship to study art and technology spaces in India, contributed to building a network of participants. He issued an open call in 2019 inviting people interested in collaborative learning and off-grid living.

The initial group consisted largely of acquaintances, he said, with participation expanding over time.Despite its unconventional structure, Mars College reflects some of the broader pressures facing traditional higher education systems. Kogan pointed to the availability of online educational content and questioned the sustainability of high tuition fees.

He noted that during the pandemic, universities such as Columbia continued charging students substantial fees even as instruction moved online.“At the age of the internet, you can get educational content for free,” he said. “But the thing that you can’t get for free is a place for young people to go through this learning phase together.”Participants at Mars College come from varied backgrounds.

Some hold advanced degrees, while others have not completed formal schooling. Current attendees include a former English major interested in off-grid living, a microbiologist with a doctorate who produces a camp journal, and individuals from nearby communities such as Slab City.

Others travel internationally and participate intermittently.Daily life at the site is shaped by environmental constraints. Strong desert winds frequently generate sandstorms, coating surfaces in dust and requiring protective measures such as goggles. Water must be transported in tanks, and waste must be removed manually.

Temperatures rise significantly during spring, often reaching triple digits.“Here, you can’t take anything for granted,” Kogan said, referring to the logistical challenges of sustaining the community.The curriculum reflects the skills required to operate in such an environment, including practical instruction in energy systems and construction.

At the same time, creative and technical subjects are integrated into the program, with participants exploring a range of projects and collaborative work.The influence of emerging technologies is also evident in the community’s activities. Workshops on coding and digital tools are common, and some systems within the camp, including lighting and organizational functions, are automated.

Participants debate how such technologies should be incorporated into creative and academic work, reflecting wider discussions taking place in educational and professional settings.Environmental concerns have also surfaced in relation to the broader region. Proposals for large-scale data infrastructure near the area have raised questions about resource use, particularly electricity and water consumption.

Kogan acknowledged encountering such discussions but said they are not central to the project’s focus, which remains on community-based learning and experimentation.Freeman described the environment as conducive to exploration and collaboration.

“It’s nice being around other people using it extensively to see what it’s capable of,” he said, referring to the range of tools and projects developed at the site.For some participants, the blending of human and automated contributions to creative work has prompted reflection.

The microbiologist who compiles the camp’s journal wrote in an editor’s note about balancing different forms of authorship and experimentation, describing it as an evolving process.The temporary nature of Mars College is a defining feature. Each year, the structures are dismantled at the end of the program, and the land returns to its unoccupied state.

Participants disperse, often returning to conventional careers or other pursuits, before reconvening the following year.The model raises questions about scalability and long-term viability, particularly in comparison with established institutions.

However, its founders emphasize that the project is not designed as a replacement for universities but as a parallel experiment.As the current session approaches its conclusion, the site is already preparing for disassembly.

The plywood classrooms, communal spaces, and solar installations will be taken down, leaving behind only the desert landscape.

Wearing a helmet fitted with a headlamp and a protective mask, molecular biologist Raúl da Silva Armando Chomela moves through the confined, low-light interiors of cave systems in central Mozambique, examining bat populations and their byproducts as part of a broader scientific effort to understand subterranean ecosystems.

Chomela, originally from the port city of Beira, has spent two years conducting research inside caves located in and around Gorongosa National Park, a 4,000 square kilometre conservation area recognized for its biodiversity.

His work focuses on bats and guano, a substance formed from accumulated bird and bat excrement that serves as a complex biological environment.“Guano is far more than just bat droppings,” Chomela said in an interview, describing it as a dynamic ecosystem.

According to his observations, guano supports a wide range of cave-dwelling organisms, including beetles, amphibians and microorganisms that have adapted to life in conditions without sunlight.

The caves in Gorongosa represent highly specialized environments. Organisms found within them have evolved to survive in stable, low-light conditions with distinct microbiomes that differ significantly from surface ecosystems.

These systems are characterized by limited external input and reliance on internal nutrient cycles, often driven by organic deposits such as guano.Chomela’s research involves entering narrow passages and descending into enclosed spaces using ropes and ladders, often without full knowledge of the terrain or species present.

According to the park’s science department, the cave networks in the region extend across approximately 183 square kilometres, forming interconnected underground systems.

More than 100 bat species have been identified in Gorongosa, although there is no precise data on how many inhabit these caves. One site, known as Tombo Aphale 5, has been extensively studied and hosts an estimated population of over 10,000 bats.

The cave is also the site of an active archaeological excavation, indicating its broader scientific relevance beyond ecological research.Gorongosa National Park was established in 1960 during Portuguese colonial administration.

Following Mozambique’s independence in 1975, conservation was not prioritized under the ruling Frelimo party. Two years later, the park became a strategic location during the country’s civil war, which involved government forces and the insurgent group Renamo.

Renamo, initially formed with support from the Rhodesian government under Ian Smith and later backed by apartheid-era South Africa, operated within the park’s terrain. During the conflict, armed groups relied on wildlife for sustenance, leading to widespread depletion of animal populations.

By the end of the war, which lasted more than 15 years, approximately 95% of the park’s wildlife had been lost, including nearly all of its estimated 5,500 hippos.The effects of the conflict extended beyond environmental damage.

Local communities experienced forced recruitment and other human rights abuses during the war, contributing to long-term social and economic challenges in the region.

In the decades since the conflict ended, Gorongosa has become the focus of sustained conservation and restoration efforts. These initiatives have involved partnerships between international institutions and Mozambican researchers, aiming to rebuild ecosystems and support local development.

One such initiative is the Paleo-Primate Project, established in 2018 as a collaboration between the University of Oxford and Gorongosa National Park. The project is led by Susana Carvalho and integrates research in archaeology, ecology and geology.

It also provides training and employment opportunities for local researchers and students.Carvalho said the broader Gorongosa Restoration Project has become a significant employer in the region, contributing to economic stability.

The project supports scientific research while also engaging local communities in conservation efforts.Chomela joined Gorongosa’s biodiversity laboratory in 2022 before becoming part of the Paleo-Primate Project in 2025.

His research spans multiple disciplines, including the use of environmental DNA to reconstruct historical ecosystems and metabarcoding techniques to analyze genetic material from bats and primates.

He is currently a first-year doctoral student at the University of Porto in Portugal, with his research based at the EO Wilson Laboratory in Chitengo, located within the park. In addition to his academic work, he leads the genetics laboratory at the facility, contributing to ongoing studies of biodiversity and ecosystem dynamics.

Chomela has also raised concerns about the potential overexploitation of guano resources. While the material is valued for its agricultural and economic uses, he noted that excessive harvesting could alter the composition of cave ecosystems.

“When they see the guano, they see money,” he said, adding that unsustainable extraction could disrupt the balance of species that depend on it.He emphasized the importance of building a scientific foundation to inform conservation practices and community engagement.

“We want a scientific base to convince the community,” he said, referring to efforts to align local economic interests with environmental sustainability.

The integration of scientific research, conservation policy and community involvement remains central to ongoing work in Gorongosa, as researchers continue to document and restore one of Africa’s most ecologically significant regions.

Global demand for sand, a key component in concrete, glass, and infrastructure development, has increased sharply in recent decades, driven by rapid urbanisation and large-scale construction projects.

According to the United Nations Environment Programme, sand and gravel are the most extracted solid materials worldwide, exceeding fossil fuels and biomass in volume.

The material is essential for producing concrete, which underpins infrastructure such as roads, bridges, housing, and commercial developments. Rapid urban expansion in emerging economies has intensified demand, particularly in regions undergoing large-scale infrastructure investment.

However, not all sand is suitable for construction. Desert sand, shaped by wind erosion, is generally too smooth for use in concrete, leading to increased extraction from riverbeds, coastlines, and marine environments.

The extraction of sand from rivers and coastal areas has raised concerns about environmental degradation. UNEP reports indicate that excessive sand mining can lead to erosion, reduced water quality, loss of biodiversity, and increased vulnerability to flooding.

River ecosystems are particularly affected, as sediment removal alters natural flow patterns and habitats.In several countries, unregulated or illegal sand mining has emerged as a governance challenge. The high demand and relatively low cost of extraction have contributed to informal markets, complicating enforcement of environmental regulations.

Governments and international organisations have begun to address the issue through policy measures aimed at sustainable resource management. UNEP has called for improved monitoring, better data collection, and the development of alternatives to natural sand, including recycled construction materials.

The growing demand for sand has implications for global supply chains and construction costs. As easily accessible sources become depleted, transportation costs increase, affecting project economics.

In some regions, sand has become a strategic resource, influencing local markets and development planning.Efforts to promote sustainable construction practices, including material efficiency and recycling, are gaining attention among policymakers and industry stakeholders.

However, large-scale adoption remains limited, and natural sand continues to dominate supply.The issue highlights the broader challenge of balancing economic growth with resource sustainability.

As urbanisation continues, the pressure on sand resources is expected to persist, requiring coordinated policy responses at national and international levels.

A growing body of scientific evidence is reinforcing the link between prolonged exposure to fine particulate matter and adverse health outcomes across northern India, particularly in densely populated urban centres. Seasonal spikes in air pollution, especially during winter months, have drawn attention to sustained exposure levels that frequently exceed national safety standards.

Residents in cities such as Delhi report recurring episodes of respiratory distress, with many describing a sense of inevitability around declining air quality.Medical practitioners have observed a steady increase in pollution-related ailments, including chronic bronchitis, asthma exacerbations, and reduced lung function.

Public health experts point to fine particulate matter, especially PM2.5, as a critical risk factor due to its ability to penetrate deep into the respiratory system and enter the bloodstream. While short-term exposure can trigger acute symptoms, long-term exposure has been associated with cardiovascular disease and reduced life expectancy.

Individuals with no prior history of respiratory illness have also reported new symptoms during peak pollution periods.

For many residents, particularly children and the elderly, exposure is not limited to outdoor environments but extends indoors due to infiltration of polluted air, raising questions about the effectiveness of mitigation measures at the household level.

Air quality deterioration in northern India is driven by a combination of local emissions and regional factors. Vehicular pollution, industrial activity, and construction dust contribute to baseline pollution levels throughout the year.

However, the onset of winter introduces additional stressors, including temperature inversions that trap pollutants close to the ground.Agricultural stubble burning in neighboring states such as Punjab and Haryana has been identified as a significant seasonal contributor.

Satellite data and atmospheric modelling have consistently indicated that smoke from crop residue burning can travel long distances, intensifying pollution episodes in urban areas downwind. Farmers, citing economic constraints and limited alternatives, continue to rely on burning as a cost-effective method for clearing fields between crop cycles.

Government data and independent monitoring agencies have reported that air quality indices during peak episodes frequently reach “severe” levels, indicating conditions that pose serious health risks even to healthy individuals.

These episodes often persist for several days, reducing visibility and disrupting daily activities, including transportation and outdoor work.

Authorities have implemented a range of measures aimed at controlling emissions, including restrictions on construction activity, temporary bans on certain vehicles, and the introduction of graded response action plans.

The Central Pollution Control Board regularly issues advisories and monitors air quality across major cities, while state governments coordinate emergency responses during critical periods.Despite these efforts, enforcement remains uneven. Analysts note that regulatory interventions are often reactive, triggered by acute pollution spikes rather than sustained preventive strategies.

Compliance challenges, particularly in informal sectors and among smaller industrial units, complicate implementation. In addition, coordination between state governments has proven difficult, especially in addressing transboundary pollution such as stubble burning.Judicial intervention has also played a role, with the Supreme Court of India periodically directing authorities to take stricter action.

However, long-term solutions require structural changes, including cleaner energy transitions, improved public transport infrastructure, and viable alternatives for agricultural waste management.

The economic impact of air pollution is increasingly evident, affecting productivity, healthcare costs, and overall quality of life. Businesses report disruptions during severe pollution episodes, while educational institutions have occasionally been forced to suspend in-person classes.

For daily wage workers and those in outdoor occupations, reduced air quality directly translates into health risks and income instability.Public awareness of pollution risks has grown, leading to increased demand for air purifiers and protective masks. However, such measures remain inaccessible to large segments of the population, highlighting disparities in exposure and protection.

Experts emphasize that while individual precautions can offer limited relief, systemic interventions are necessary to address the scale of the problem.Scientific studies continue to underline the cumulative impact of chronic exposure, suggesting that air pollution is not only an environmental issue but also a major public health challenge.

As evidence mounts, policymakers face increasing pressure to shift from short-term mitigation to comprehensive, long-term strategies that address both sources and structural drivers of pollution in India’s rapidly urbanizing regions.

The new unit reflects J.P. Morgan’s strategic shift toward relationship-driven advisory, offering select clients deeper access to global expertise across emerging and transformative sectors.

J.P. Morgan has announced the launch of a new Special Advisory Services unit, marking a significant step in the bank’s efforts to strengthen long-term relationships with its most valued clients. The initiative is designed to go beyond traditional dealmaking and financing, positioning the firm as a strategic partner in an increasingly complex global business environment.

The move comes at a time when companies are seeking more nuanced guidance amid rapid technological change, geopolitical uncertainty, and evolving regulatory and market conditions. By creating a dedicated advisory platform, J.P. Morgan aims to deliver forward-looking insights that help clients navigate both immediate challenges and long-term opportunities.

The Special Advisory Services unit will provide tailored advice on a wide range of themes shaping global markets today. These include artificial intelligence, cybersecurity, digital assets, geopolitics, healthcare innovation, supply chain resilience, and sustainability, all of which are becoming central to corporate decision-making.

Rather than focusing solely on transactions, the new unit emphasizes strategic thinking and continuity. It is structured to support clients over extended time horizons, helping leadership teams anticipate shifts, assess risks, and align business strategies with emerging global trends.

Leadership of the unit has been entrusted to Liz Myers, global chair of investment banking at J.P. Morgan. With more than three decades of experience at the firm, Myers brings deep institutional knowledge and a proven track record in advising companies through complex capital markets and growth phases.

Her previous role overseeing global equity capital markets has equipped her with a broad perspective on investor expectations, market cycles, and corporate transformation. Under her leadership, the new advisory unit is expected to integrate insights from across J.P. Morgan’s global network and sector expertise.

The bank has indicated that the unit will serve a select group of long-standing, top-tier clients. This includes companies preparing for initial public offerings, established corporates pursuing transformational mergers or acquisitions, and mid-sized firms seeking to make J.P. Morgan their primary banking partner.

By focusing on depth rather than volume, J.P. Morgan is reinforcing its commitment to relationship banking. The approach reflects a belief that clients increasingly value trusted advisers who can provide consistent guidance across multiple business cycles, rather than transactional support alone.

Industry observers note that the investment advisory services market is expected to expand in 2026, driven by greater adoption of advanced technologies and rising demand for specialized expertise. J.P. Morgan’s new unit positions the firm to meet this demand with a differentiated, high-touch offering.

The initiative also aligns with broader shifts in the financial services sector, where advisory capabilities are becoming a key competitive advantage. As companies face interconnected risks spanning technology, politics, and sustainability, integrated advice is emerging as a critical need.

Through the Special Advisory Services unit, J.P. Morgan aims to deepen trust, enhance strategic relevance, and reinforce its role as a long-term partner to global businesses. The launch underscores the firm’s confidence in advisory-led growth and its commitment to evolving alongside client needs.
