Indonesian social forestry often excludes women from decisions, risking greater inequality

Our analysis of Indonesia’s social forestry permits shows that women remain underrepresented in forest management bodies despite efforts to boost their presence, leaving them out of decisions about their forests.

Social forestry redistributes forest management rights to local communities to advance sustainability and local livelihoods. In 2021, the country revised its social forestry regulations to allow one family representative to participate in social forestry management bodies, ‘giving equal opportunity to both men and women.’

However, our analysis of 400 most recent social forestry permit documents, combined with extended, multi-method field research at four sites, shows that women are often excluded from management bodies but are more involved in social forestry business groups (Kelompok Usaha Perhutanan Sosial or KUPS). These groups focus on the processing and sale of forest products.

This low level of participation in management excludes women from decisions about who receives benefits such as land for cultivation, seedlings, equipment, extension training, and technical information provided by the government and NGOs. The absence of women’s presence may deepen local inequalities and hamper effective forest management.

Gender gaps in social forestry

We reviewed the 400 most recent decree letters issued in 2024 that granted forestry management rights. These included 100 permits each for the managements of Village Forests (Hutan Desa) and Community Forests (Hutan Kemasyarakatan) and their respective KUPS (Table 1). Village Forests are rights collectively held and managed by village administrations, while Community Forests are issued to specific farmer or community groups.

Our analysis found that across Indonesia women are often underrepresented in management groups. On average, only 19.54% of members in Village Forest’s management bodies were women, with participation ranging from none to 80%. This number was even lower in Community Forests, averaging 13.95% women, with some groups having no female members and others up to 56.52%.

However, the available data often lacked details about gender in KUPS-related decrees. Only 19 of 100 Village Forests’ KUPS decrees and 23 of 100 Community Forests’ KUPS decrees included this information.

When gender data was included, women were more involved in KUPS of Village Forests, with an average of 46.32% participation. In contrast, their participation in Community Forests’ KUPS was just 13.06%.

These numbers show that progress in gender representation in Indonesia’s social forestry is mixed. While women are more active in economic activities linked to KUPS, they are still sidelined in formal management roles and decision-making.

Understanding uneven participation

Our field research also highlighted how women and men are participating in, and deriving benefits from, social forestry in Indonesia, while exploring factors influencing women’s (and men’s) involvement.

We focused on four social forestry sites — two Village Forests (Sintang; West Kalimantan province, and Muara Enim; South Sumatra province) and two Community Forests (Gunungkidul; Special Region of Yogyakarta, and Enrekang; South Sulawesi province). We selected sites that reflect different levels of women’s participation.

Table 2 highlights a disparity: while women actively engage in forest land use — such as collecting and processing non-timber forest products and cultivating social forestry land — in two sites (Enrekang and Muara Enim) they are not involved in management bodies where decisions about land use, forest resources and benefit distribution are made.

For example, Masna (pseudonym), a farmer and forest user from Enrekang, shared that her involvement in her village’s forest management body (Kelompok Tani Hutan) was limited to preparing snacks while men made decisions.

Why does this happen?

Deeply rooted gender norms significantly limit women’s involvement in social forestry in some sites. These norms often designate unpaid household and care-giving duties to women, positioning men as the primary decision-makers. This affects women’s confidence and participation in village meetings, where forest management decisions are made reduce women’s participation.

Our findings align with earlier studies showing how gender roles, influenced by discourse promoted by the New Order regime, continue to shape these practices of recognising men as breadwinners and landowners, reinforcing their dominance in formal discussions and decision-making bodies.

Although there are no educational requirements for joining social forestry, research shows that those with more education tend to have more influence. In our study, women in social forestry households averaged fewer years of education (6.6 years) compared to men (8.1 years). Lower education levels, socio-economic challenges, and low confidence in public forums, where education often boosts credibility, can further exclude women.

Geographic barriers such as remote forest locations, rough terrain, and poor roads also hinder women’s participation, making travel difficult and limiting their ability to be involved.

Assistance helps, as do local women leaders

In the Sintang and Gunungkidul sites, women have taken on greater roles in forest management bodies.

In Sintang, support from the Indonesian NGO PUPUK (Association for the Improvement of Small Business) significantly boosted women’s participation in the village forest management body. PUPUK facilitated discussions, provided training at convenient times for women, and encouraged male leaders to back greater female involvement. The number of female members increased from just one in 2018 to 12 women and nine men in a newly formed management body in 2022.

The social forestry group in Gunungkidul – initially a male-dominated, government-led reforestation project – evolved into a community-driven initiative with strong female leadership. Support from both government and NGOs enabled women to take more active roles in forestry and agriculture, especially as many men (and some women) left to seek work elsewhere.

A university-educated woman now leads this group and has inspired younger women to join forest management and KUPS activities. These include producing traditional herbal drinks (wedang uwuh) and making snacks from taro, cassava, and arrowroot grown on forest land.

Across the study sites, women involved in KUPS have developed skills in forest management, financial planning, product processing, and marketing, earning modest incomes. These activities have also shifted gender roles. For example, in Sintang, when Mirna (pseudonym) became head of the KUPS, her husband started taking on domestic chores like cooking and childcare to support her work.

What’s next?

Tackling gender disparities in social forestry requires targeted policies to ensure women’s voices, especially from marginalised groups, are heard in decision-making processes that affect their livelihoods and access to resources.

Introducing quotas or affirmative measures for forest management bodies can help close the gender gap and ensure more equitable benefit distribution. Evidence from other Global South regions suggests that at least 30% female representation in forest management bodies is necessary for meaningful participation, enabling women to influence decisions more effectively.

Inclusive governance also depends on fair representation of different ethnic and socio-economic groups, particularly poorer households. When disadvantaged groups are poorly represented, the distribution of benefits suffers, limiting the equitable flow of resources and opportunities.

Partnerships with NGOs and civil society groups skilled in addressing gender differences can empower women and marginalized men with the skills and confidence needed to engage in decision-making bodies.

Creating safe spaces is also vital. This includes holding gender-specific discussions in local languages at times that fit with both women’s and men’s schedules.

The government must also commit to regularly monitoring women’s participation by collecting and publishing accurate gender-disaggregated data, specific to each site and region.

A decree issued by Ministry of Environment and Forestry in August introduces a policy shift that allows individuals — not just groups — to apply for social forestry. This could boost women’s participation, provided targeted support helps them step into leadership roles. Without this backing, the risk remains that social forestry will continue to be dominated by elite men.

Reflecting on 20 years of the Aceh tsunami: From ‘megathrust’ threat to disaster mitigation

Source: The Conversation – Indonesia – By Zulfakriza Z., Associate Professor, Global Geophysics Research Group, Institut Teknologi Bandung

20 years have passed since the Aceh tsunami, which left deep scars on Indonesia, especially for those directly affected. Aceh was also recovering from a three-decade armed conflict between the Free Aceh Movement and the national government

Throughout December 2024, The Conversation Indonesia, in collaboration with academics, is publishing a special edition honouring the 20 years of efforts to rebuild Aceh. We hope this series of articles preserves our collective memory while inspiring reflection on the journey of recovery and peace in the land of ‘Serambi Makkah.’


Sunday, December 26, 2004, 7:58:53 AM (WIB, GMT+7): A 9.1 moment magnitude (Mw) earthquake occurred off the west coast of Aceh. The quake, originating from a depth of 30 kilometers below the sea, triggered a tsunami that devastated the province.

Research in 2021 suggested the earthquake’s magnitude was actually greater than what was previously recorded — 9.2 Mw. Scientists came to this conclusion after recalculating tsunami data using Green’s Function, a mathematical method that analyses how tsunami waves are formed and spread. This gave them a more accurate estimate of how strong the earthquake was.

From December 26, 2004, to February 26, 2005, the United States Geological Survey (USGS) documented about 2,050 aftershocks, a series of aftershock caused by the mainshock.

The effects of the 2004 Aceh earthquake and tsunami extended beyond Indonesia, affecting coastlines in Southeast Asia, South Asia, and possibly Africa. More than 227,000 people were killed, with Aceh alone accounting for approximately 167,000.

The 2004 Aceh Earthquake and Tsunami is known as one of the most devastating natural disasters in history. While it left deep wounds, it also demonstrated the fundamental need for disaster preparedness.

Tectonic map, megathrust zones, and seismic gaps

Indonesia is prone to disasters due to its location in a tectonically active zone where four major plates — Indo-Australian, Eurasian, Pacific, and Philippine — with convergence movement.

Comprising Earth’s rigid outer layer or lithosphere, a tectonic plate is a large, irregularly shaped sheet of solid rock that moves and interacts with other plates to sculpt the surface of the planet over geological time. These plate clashes have the potential to trigger massive earthquakes, particularly in western Sumatra, southern Java, Bali, Nusa Tenggara, the Banda Sea, Maluku, Papua, and Sulawesi.

A shift between two tectonic plates in the Indian Ocean resulted in a thrust fault, causing the 2004 Aceh earthquake. The fault stretched 500 kilometers – roughly the distance between Jakarta and Yogyakarta – with a breadth of about 150 kilometers. Known as a “megathrust earthquake,” the plates shifted by more than 20 meters, releasing enormous energy and causing tsunami waves up to 35 meters high – the height of a 10-story building.

Aside from earthquakes and tsunamis, tectonic movements can also trigger volcanic activity. Indonesia, which is part of the Pacific Ring of Fire, has 127 active volcanoes, making it the world’s most seismically and volcanically active region.

Between 1900 and 2023, Indonesia recorded 14,820 earthquakes with magnitudes greater than 5 Mw. Among these, 15 were more than 8 Mw, including the 2004 Aceh earthquake. Other big earthquakes, like those in Sumba (1977), Biak (1996), Nias (2005), and Bengkulu (2007), also triggered tsunamis, causing substantial casualties and damage.

Indonesia also has several megathrust zones – areas along tectonic plate boundaries prone to generating large earthquakes like the 2004 Aceh event. There are 13 identified megathrust zones near the waters off western Sumatra, southern Java, Bali, Nusa Tenggara, northern Sulawesi, Halmahera, and Papua. These zones are prone to generate quakes of magnitudes ranging from 7.8 to 9.2 Mw, capable of delivering major destruction and tsunamis.

Over the last 30 years, some of Indonesia’s megathrust zones have been releasing seismic energy. These zones were the source of major earthquakes such as 1996 Biak, 1994 Banyuwangi, 2004 Aceh, 2005 Nias, 2006 Pangandaran, and 2007 Bengkulu.

However, data from the past 123 years show that some parts of the megathrust zones rarely experience large earthquakes. This could be because tectonic movements in these locations are stuck, causing stress to build up over time. These “seismic gaps” indicate high-risk zones for future big earthquakes.

A seismic gap, for example, exists between the megathrust zones off the western and eastern coasts of Java. For instance, in western Java’s subduction zone, the slip deficit — or plate movement locked in place — has reached 40-60 mm per year. If this energy is eventually released, it might result in a significant earthquake and possibly a tsunami.

Advances in disaster research

Indonesia’s high disaster risk has attracted scholars from all around the world, particularly following the 2004 Aceh Tsunami. From 2005 to 2024, Google Scholar recorded approximately 1,000 scientific works on Indonesian earthquakes and tsunamis.

These studies have improved our understanding of earthquake causes and trends. For example, research on the 2018 Palu and Sunda Strait tsunamis revealed that neither was directly caused by earthquakes. The Palu tsunami resulted from an undersea landslide triggered by a 7.5 Mw earthquake on September 28, 2018. Meanwhile, the Sunda Strait tsunami was caused by the fall of Mount Anak Krakatau’s volcanic side.

Indonesian academics have also investigated big earthquake origins and aftershocks. Teams from the National Research and Innovation Agency (BRIN), the Meteorology, Climatology, and Geophysics Agency (BMKG), and the Bandung Institute of Technology (ITB) have looked at aftershock patterns to learn more about where earthquakes come from and how they work. Among those closely studied are 2018 Lombok and 2022 Cianjur. This has led to new ideas for reducing risk and damage.

The Indonesian Tsunami Early Warning System (InaTEWS), managed by BMKG, continues to encourage seismic research collaborations. By 2024, the system would have 521 seismic stations spread across Indonesia. This extensive network allows for faster broadcast of earthquake data to the public, notably timely tsunami warnings after major earthquakes.

Mitigation requires collaboration

While scientists continue to investigate tectonic motions, accurately predicting earthquakes and tsunamis remains impossible. Therefore, mitigation and risk reduction are crucial.

Disaster mitigation efforts include public education and the use of earthquake-resistant infrastructure. These require the support of a wide range of stakeholders.

In 2007, three years after the Aceh Tsunami, Indonesia passed a Disaster Management Law, detailing risk reduction activities, including mitigation. This law promotes collaboration among five major elements: government, communities, academics, corporations, and the media — a framework known as the “pentahelix.”

The government acts as a regulator, the media disseminates information, corporations provide financial and technological support, communities serve as field implementers, and academics act as innovators.

Collaboration is essential for successful catastrophe mitigation. However, problems such as sectoral ego frequently impede efforts. For example, a refusal to share data across authorities can jeopardise earthquake research and mitigation efforts.

Finally, disaster risk mitigation is a shared responsibility. Building a more robust and sustainable mitigation system requires improved institutional coordination and communication.

Lessons from Aceh: How language unites and segregates in conflicts

Source: The Conversation – Indonesia – By Saiful Akmal, Chair professor, Universitas Islam Negeri Ar-Raniry

20 years have passed since the Aceh tsunami, leaving deep scars on Indonesia, especially for those directly affected. Aceh was also recovering from a three-decade armed conflict between the Free Aceh Movement and the national government

Throughout December 2024, The Conversation Indonesia, in collaboration with academics, is publishing a special edition honouring the 20 years of efforts to rebuild Aceh. We hope this series of articles preserves our collective memory while inspiring reflection on the journey of recovery and peace in the land of ‘Serambi Makkah.’


In December 2022, the Aceh People’s Representative Council (DPR) officially enacted the 2022 Qanun (regional regulation) on the Acehnese language. This regulation mandates that the use of Indonesian, in any form of communications, from scientific works to public services, must be accompanies by Acehnese translations. This move reflects Aceh’s autonomy in preserving local cultures, a key demand of the now-defunct Free Aceh Movement (GAM), which sought independence from Indonesia.

The Aceh conflict that ended with the signing of a peace agreement in August 2005, less than a year after the Aceh devastating tsunami, stemmed from locals’ dissatisfaction with the central government. The separatist movement was triggered by economic inequality and natural resource exploitation.

The Qanun reaffirms the Indonesian government and GAM’s commitment to peace following three-decade armed conflict, as outlined in the 2005 Helsinki Agreement. Language — as an important element in culture — can aid in resolving conflicts. It can reduce psychological barriers and foster trust. Local languages, in particular, can strenthen nationalism by promoting empathy and cultural appreciation.

Language for political mobilisation

The use of language can excarcebate conflicts. It can be used to agitate and mobilise people, create hostile narratives, and be used as a propaganda tool to assert group identity and define friends and foes.

During Soeharto’s dictatorship era, the government’s nationalism policy emphasised the exclusive use of Indonesian as national language, even in regions with strong local cultures and languages like Aceh. Local languages are considered less important than Indonesian. This has led to a decline in the use and teaching of local languages in schools, which in turn can threaten the survival and development of these languages.

During the conflict, using Acehnese could be risky, especially in areas sympathetic to GAM. Speaking local language could lead to accusation of supporting the movement, often resulting in intimidation and arrests by the Indonesian military.

GAM, on the other hand, used Acehnese to raise people’s spirit and gather support during the conflict. Cassettes with songs in local languages played in villages created a sense of solidarity while drawing a stark line between “us” and “them.” This demonstrates how language can be a powerful tool in social and political mobilisation.

Language for conflict resolution

In Aceh, the role of local language in promoting conflict resolution is significant for the following reasons:

1. Reduces psychological barriers

In 2005, Hamid Awaluddin, a Bugis descendant and former Minister of Justice and Human Rights who represented the government in the negotiation of conflict resolution in Aceh, read ‘pantun’, a traditional Malay poem, in Acehnese:

pat ujeun yang hana pirang, pat prang yang hana reuda,” (is there rain that will not stop? Is there a war that cannot be ended?).

Although his Acehnese was not fluent, Hamid’s efforts were warmly received by Wali Nanggroe, Aceh’s cultural leadership, and other people who represented the local communities. His decision to use the local language had created an intimate atmosphere, which then helped reduce tension and increased mutual trust between the two parties.

Language in such contexts becomes a powerful instrument in a peace negotiation process, serving not only as a technical communication tool, but also as a symbol of empathy and respect. It allows the conflicting parties to feel more valued and share emotions, which then can pave the way for a more constructive and inclusive dialogue.

2. Strengthening the sense of nationalism

Case studies show that the recognition of the Acehnese language, identity and culture by the central government can foster Indonesian nationalism among the local communities. According to a research, building something from within, and respecting local conditions contributes to a more permanent peace-building effort.

The government’s move to acknowledge local languages of Aceh and Gayo as intangible heritages has allowed the people to use them in public spaces. As a result, this strengthened the sense of belonging of Acehnese people to the state

By providing space to local languages, the state shows respect for existing cultural diversity–allowing local communities feel more integrated with the national framework.

An inclusive approach

The establishment of the Acehnese Language Qanun is not without risks. While it is true that the Acehnese Language Qanun can increase nationalism because it makes people feel appreciated and recognised, it may negatively impact other ethnic languages.

Aceh is home to 13 other local languages. Enacting Acehnese as an official regional language can make non-Acehnese groups feel isolated, as evidenced by past protests from the Gayo community and other minorities.

For example, protests arose when being fluent in Acehnese became one of the requirements to become a local leader such as a Wali Nanggroe. Additionally, replacing the Gayo hymn with the Acehnese hymn in ceremonial activities has angered the Gayo people as the majority ethnic group in the area.

Without proper mitigation, this policy risks alienating minority groups, potentially leading to feelings of forced assimilation for minority languages. This will harm the efforts to build sustainable peace in Aceh. Therefore, an inclusive approach to language policy is very important.

The efforts to promote the Acehnese language should be accompanied by similar steps to recognise and preserve the languages and cultural expressions of other ethnic groups in Aceh.

This inclusive approach is crucial to building long-term peace and social cohesion in the region. After all, Aceh’s experience teaches us that language has two sides in conflict resolution: as a tool that strengthens peace, or sharpens differences.

High skills, low protection: the legal hurdles for foreign workers in Indonesia

Source: The Conversation – Indonesia – By Wayne Palmer, Senior Research Fellow, Bielefeld University

ilikeyellow/Shutterstock

Developing countries like Indonesia use foreign high-skilled and high-wage workers to drive economic growth and innovation. However, protection of their legal rights is often neglected, affecting these workers’ productivity and well-being and Indonesia’s reputation as a destination country for employment.

My research delves into the flaws of Indonesia’s labour market institutions, such as the national labour dispute settlement system, revealing that current mechanisms are inadequate in protecting the rights of high-skilled foreign workers.

The study

My findings show the national dispute settlement system exhibits significant systemic shortcomings, such as processing cases slowly and siding with employers, which limit its capacity to protect all workers effectively. But disputes involving foreign workers are further complicated by the fact that immigration law allows employers to cancel residence permits, meaning that the government requires the workers to leave the country even though the workers may have been unfairly dismissed.

Foreign workers are mainly from Northeast Asia (China, Japan and Korea), and their use on investment-tied projects coupled with Indonesia’s downstreaming programme will ensure their numbers continue to grow. In 2023, the Indonesian government issued 168,048 permits for foreigners to work in Indonesia with the top three destinations being Central Sulawesi (18,678), Jakarta (13,862) and West Java (10,807). By July 2024, the government had already issued more than 14% more permits than by the same time the previous year.

My study examined 92 labour disputes involving foreign workers between 2006 (when the new national dispute settlement system was implemented) and 2022, which were settled by the Industrial Relations Court. One additional dispute was filed in 2023, but the Industrial Relations Court has not yet published the settlement despite a legal requirement to do so.

I complemented these court settlements with 98 qualitative interviews with other stakeholders, including policymakers, labour rights activists, legal professionals, and other foreign workers, such as foreign spouses, remote workers and digital nomads.

As in other countries too, the number of registered labour disputes is only the tip of the iceberg, as workers tend to cut their losses and move on rather than invest time, energy and limited financial resources in challenging their better-resourced employers.

Employers were all Indonesian companies, so no foreign workers who filed a lawsuit worked for a multinational company, and those who did so had at least 20 nationalities.

In terms of geographical distribution, the studied disputes were settled in 13 local jurisdictions, and were mostly lodged by workers rather than employers.

The nature of the disputes mostly involved claims that an employment contract had been terminated prematurely (87 cases), while a much smaller number involved resignation (4 cases) or were unknown (1 case). Of the 92 claims, 83 were initiated by workers, and eight by an employer. In one case, the lodging party was not recorded in the final decision.

Hiring a private lawyer

Employers used the Immigration Law to undermine the protective role of the Manpower Law – as it stands foreign workers are only entitled to employment protection if they hold a valid residence permit, which employers can and do shorten. Doing so shows that the Indonesian government prioritizes the flexibility of employers at the expense of employment protection for foreign workers.

In at least 92% cases, foreign workers used paid assistance of a private lawyer to represent themselves at formal meetings and hearings required by the Disputes Settlement Law, the cost of which could be hefty.

As one foreign worker explained:

It’s always in the back of your mind, to do whatever to make employers happy if you want to stay. No matter what the work permit and contract say, they can ask immigration to kick us out within a week!“

A retired government official responsible for designing policy regarding foreign workers was surprised when he heard this, explaining that:

I thought they could look after themselves because they earn such high wages. Well, higher than the average Indonesian worker, that is.

Hiring a private lawyer is the only way to represent themselves throughout the dispute resolution process because they need to leave Indonesia once they are fired. Not having the legal right to remain in Indonesia makes it very difficult – even impossible – to do it without them.

Addressing institutional failures

Engaging a private lawyer served as an ‘institutional fix’ that enabled most foreign workers to engage with Indonesia’s labour dispute settlement system by attending formal meetings and hearings, as well as filling out required paperwork and sending essential letters and replies.

Addressing this institutional failure requires a shift in law and policy. Firstly, legal reforms are essential to ensure that immigration and employment laws are integrated to enable foreign workers to have access to legal processes intended to help protect labour rights. At a minimum, this would involve amending policy to prevent employers from cancelling residence permits so that foreign workers need to leave the country prematurely.

Alternatively, the Directorate-General of Immigration could still permit employers to do so, but then provide the affected foreign workers with a limited-stay visa so that they can remain in Indonesia to engage with the legal process. The Hong Kong Immigration Department does this for Indonesian migrant workers.

Secondly, there is a need for enhanced support systems that provide immediate and effective assistance to foreign workers. Government agencies tasked with settling labour disputes, such as local manpower offices and the Industrial Relations Court, should be equipped with adequate resources and trained personnel to handle migrant labour issues. Doing so would decrease the reliance of foreign workers on private lawyers.

Failure to protect the employment rights of foreign workers has the potential to damage Indonesia’s reputation as a destination country for employment. Such damage could undermine Indonesia’s ambitious plans to build a new capital city (Ibu Kota Nusantara) with the assistance of foreign workers, and undermine the government’s downstreaming programme, which helps Indonesia earn more from the export of raw minerals.

There’s gold trapped in your iPhone – and chemists have found a safe new way to extract it

Source: The Conversation – Canada – By Justin M. Chalker, Professor of Chemistry, Flinders University

A sample of refined gold recovered from mining and e-waste recycling trials. Justin Chalker

In 2022, humans produced an estimated 62 million tonnes of electronic waste – enough to fill more than 1.5 million garbage trucks. This was up 82% from 2010 and is expected to rise to 82 million tonnes in 2030.

This e-waste includes old laptops and phones, which contain precious materials such as gold. Less than one quarter of it is properly collected and recycled. But a new technique colleagues and I have developed to safely and sustainably extract gold from e-waste could help change that.

Our new gold-extraction technique, which we describe in a new paper published today in Nature Sustainability, could also make small-scale gold mining less poisonous for people – and the planet.

Soaring global demand

Gold has long played a crucial role in human life. It has been a form of currency and a medium for art and fashion for centuries. Gold is also essential in modern industries including the electronics, chemical manufacture and aerospace sectors.

But while global demand for this precious metal is soaring, mining it is harmful to the environment.

Deforestation and use of toxic chemicals are two such problems. In formal, large-scale mining, highly toxic cyanide is widely used to extract gold from ore. While cyanide can be degraded, its use can cause harm to wildlife, and tailings dams which store the toxic byproducts of mining operations pose a risk to the wider environment.

In small-scale and artisanal mining, mercury is used extensively to extract gold. In this practice, the gold reacts with mercury to form a dense amalgam that can be easily isolated. The gold is then recovered by heating the amalgam to vaporise the mercury.

Small-scale and artisanal mining is the largest source of mercury pollution on Earth, and the mercury emissions are dangerous to the miners and pollute the environment. New methods are required to reduce the impacts of gold mining.

A safer alternative

Our interdisciplinary team of scientists and engineers has developed a new technique to extract gold from ore and e-waste. The aim was to provide a safer alternative to mercury and cyanide and reduce the health and environmental impacts of gold mining.

Many techniques have previously been reported for extracting gold from ore or e-waste, including mercury- and cyanide-free methods. However, many of these methods are limited in rate, yield, scale and cost. Often these methods also consider only one step in the entire gold recovery process, and recycling and waste management is often neglected.

In contrast, our approach considered sustainability throughout the whole process of gold extraction, recovery and refining. Our new leaching technology uses a chemical commonly used in water sanitation and pool chlorination: trichloroisocyanuric acid.

When this widely available and low-cost chemical is activated with salt water, it can react with gold and convert it into a water-soluble form.

To recover the gold from the solution, we invented a sulphur-rich polymer sorbent. Polymer sorbents isolate a certain substance from a liquid or gas, and ours is made by joining a key building block (a monomer) together through a chain reaction.

Our polymer sorbent is interesting because it is derived from elemental sulphur: a low-cost and highly abundant feedstock. The petroleum sector generates more sulphur than it can use or sell, so our polymer synthesis is a new use for this underused resource.

Our polymer could selectively bind and remove gold from the solution, even when many other types of metals were present in the mixture.

The simple leaching and recovery methods were demonstrated on ore, circuit boards from obsolete computers and scientific waste. Importantly, we also developed methods to regenerate and recycle both the leaching chemical and the polymer sorbent. We also established methods to purify and recycle the water used in the process.

In developing the recyclable polymer sorbent, we invented some exciting new chemistry to make the polymer using light, and then “un-make” the sorbent after it bound gold. This recycling method converted the polymer back to its original monomer building block and separated it from the gold.

The recovered monomer could then be re-made into the gold-binding polymer: an important demonstration of how the process is aligned with a circular economy.

A long and complex road ahead

In future work, we plan to collaborate with industry, government and not-for-profit groups to test our method in small-scale mining operations. Our long-term aim is to provide a robust and safe method for extracting gold, eliminating the need for highly toxic chemicals such as cyanide and mercury.

There will be many challenges to overcome including scaling up the production of the polymer sorbent and the chemical recycling processes. For uptake, we also need to ensure that the rate, yield and cost are competitive with more traditional methods of gold mining. Our preliminary results are encouraging. But there is still a long and complex road ahead before our new techniques replace cyanide and mercury.

Our broader motivation is to support the livelihood of the millions of artisanal and small-scale miners that rely on mercury to recover gold.

They typically operate in remote and rural regions with few other economic opportunities. Our goal is to support these miners economically while offering safer alternatives to mercury. Likewise, the rise of “urban mining” and e-waste recycling would benefit from safer and operationally simple methods for precious metal recovery.

Success in recovering gold from e-waste will also reduce the need for primary mining and therefore lessen its environmental impact.

How old are you really? Are the latest ‘biological age’ tests all they’re cracked up to be?

Source: The Conversation – Canada – By Hassan Vally, Associate Professor, Epidemiology, Deakin University

We all like to imagine we’re ageing well. Now a simple blood or saliva test promises to tell us by measuring our “biological age”. And then, as many have done, we can share how “young” we really are on social media, along with our secrets to success.

While chronological age is how long you have been alive, measures of biological age aim to indicate how old your body actually is, purporting to measure “wear and tear” at a molecular level.

The appeal of these tests is undeniable. Health-conscious consumers may see their results as reinforcing their anti-ageing efforts, or a way to show their journey to better health is paying off.

But how good are these tests? Do they actually offer useful insights? Or are they just clever marketing dressed up to look like science?

How do these tests work?

Over time, the chemical processes that allow our body to function, known as our “metabolic activity”, lead to damage and a decline in the activity of our cells, tissues and organs.

Biological age tests aim to capture some of these changes, offering a snapshot of how well, or how poorly, we are ageing on a cellular level.

Our DNA is also affected by the ageing process. In particular, chemical tags (methyl groups) attach to our DNA and affect gene expression. These changes occur in predictable ways with age and environmental exposures, in a process called methylation.

Research studies have used “epigenetic clocks”, which measure the methylation of our genes, to estimate biological age. By analysing methylation levels at specific sites in the genome from participant samples, researchers apply predictive models to estimate the cumulative wear and tear on the body.

What does the research say about their use?

Although the science is rapidly evolving, the evidence underpinning the use of epigenetic clocks to measure biological ageing in research studies is strong.

Studies have shown epigenetic biological age estimation is a better predictor of the risk of death and ageing-related diseases than chronological age.

Epigenetic clocks also have been found to correlate strongly with lifestyle and environmental exposures, such as smoking status and diet quality.

In addition, they have been found to be able to predict the risk of conditions such as cardiovascular disease, which can lead to heart attacks and strokes.

Taken together, a growing body of research indicates that at a population level, epigenetic clocks are robust measures of biological ageing and are strongly linked to the risk of disease and death

But how good are these tests for individuals?

While these tests are valuable when studying populations in research settings, using epigenetic clocks to measure the biological age of individuals is a different matter and requires scrutiny.

For testing at an individual level, perhaps the most important consideration is the “signal to noise ratio” (or precision) of these tests. This is the question of whether a single sample from an individual may yield widely differing results.

A study from 2022 found samples deviated by up to nine years. So an identical sample from a 40-year-old may indicate a biological age of as low as 35 years (a cause for celebration) or as high as 44 years (a cause of anxiety).

While there have been significant improvements in these tests over the years, there is considerable variability in the precision of these tests between commercial providers. So depending on who you send your sample to, your estimated biological age may vary considerably.

Another limitation is there is currently no standardisation of methods for this testing. Commercial providers perform these tests in different ways and have different algorithms for estimating biological age from the data.

As you would expect for commercial operators, providers don’t disclose their methods. So it’s difficult to compare companies and determine who provides the most accurate results – and what you’re getting for your money.

A third limitation is that while epigenetic clocks correlate well with ageing, they are simply a “proxy” and are not a diagnostic tool.

In other words, they may provide a general indication of ageing at a cellular level. But they don’t offer any specific insights about what the issue may be if someone is found to be “ageing faster” than they would like, or what they’re doing right if they are “ageing well”.

So regardless of the result of your test, all you’re likely to get from the commercial provider of an epigenetic test is generic advice about what the science says is healthy behaviour.

Are they worth it? Or what should I do instead?

While companies offering these tests may have good intentions, remember their ultimate goal is to sell you these tests and make a profit. And at a cost of around A$500, they’re not cheap.

While the idea of using these tests as a personalised health tool has potential, it is clear that we are not there yet.

For this to become a reality, tests will need to become more reproducible, standardised across providers, and validated through long-term studies that link changes in biological age to specific behaviours.

So while one-off tests of biological age make for impressive social media posts, for most people they represent a significant cost and offer limited real value.

The good news is we already know what we need to do to increase our chances of living longer and healthier lives. These include:

  • improving our diet
  • increasing physical activity
  • getting enough sleep
  • quitting smoking
  • reducing stress
  • prioritising social connection.

We don’t need to know our biological age in order to implement changes in our lives right now to improve our health.

Bats get fat to survive hard times. But climate change is threatening their survival strategy

Bats are often cast as the unseen night-time stewards of nature, flitting through the dark to control pest insects, pollinate plants and disperse seeds. But behind their silent contributions lies a remarkable and underappreciated survival strategy: seasonal fattening.

Much like bears and squirrels, bats around the world bulk up to get through hard times – even in places where you might not expect it.

In a paper published today in Ecology Letters, we analysed data from bat studies around the world to understand how bats use body fat to survive seasonal challenges, whether it’s a freezing winter or a dry spell.

The surprising conclusion? Seasonal fattening is a global phenomenon in bats, not just limited to those in cold climates.

Even bats in the tropics, where it’s warm all year, store fat in anticipation of dry seasons when food becomes scarce. That’s a survival strategy that’s been largely overlooked. But it may be faltering as the climate changes, putting entire food webs at risk.

Climate shapes fattening strategies

We found bats in colder regions predictably gain more weight before winter.

But in warmer regions with highly seasonal rainfall, such as tropical savannas or monsoonal forests, bats also fatten up. In tropical areas, it’s not cold that’s the enemy, but the dry season, when flowers wither, insects vanish and energy is hard to come by.

The extent of fattening is impressive. Some species increased their body weight by more than 50%, which is a huge burden for flying animals that already use a lot of energy to move around. This highlights the delicate balancing act bats perform between storing energy and staying nimble in the air.

Sex matters, especially in the cold

The results also support the “thrifty females, frisky males” hypothesis.

In colder climates, female bats used their fat reserves more sparingly than males – a likely adaptation to ensure they have enough energy left to raise young when spring returns. Since females typically emerge from hibernation to raise their young, conserving fat through winter can directly benefit their reproductive success.

Interestingly, this sex-based difference vanished in warmer climates, where fat use by males and females was more similar, likely because more food is available in warmer climates. It’s another clue that climate patterns intricately shape behaviour and physiology.

Climate change is shifting the rules

Beyond the biology, our study points to a more sobering trend. Bats in warm regions appear to be increasing their fat stores over time. This could be an early warning sign of how climate change is affecting their survival.

Climate change isn’t just about rising temperatures. It’s also making seasons more unpredictable.

Bats may be storing more energy in advance of dry seasons that are becoming longer or harder to predict. That’s risky, because it means more foraging, more exposure to predators and potentially greater mortality.

The implications can ripple outward. Bats help regulate insect populations, fertilise crops and maintain healthy ecosystems. If their survival strategies falter, entire food webs could feel the effects.

Fat bats, fragile futures

Our study changes how we think about bats. They are not just passive victims of environmental change but active strategists, finely tuned to seasonal rhythms. Yet their ability to adapt has limits, and those limits are being tested by a rapidly changing world.

By understanding how bats respond to climate, we gain insights into broader ecosystem resilience. We also gain a deeper appreciation for one of nature’s quiet heroes – fattening up, flying through the night and holding ecosystems together, one wingbeat at a time.

What’s the difference between an eating disorder and disordered eating?

Source: The Conversation – Canada – By Gemma Sharp, Researcher in Body Image, Eating and Weight Disorders, Monash University

Following a particular diet or exercising a great deal are common and even encouraged in our health and image-conscious culture. With increased awareness of food allergies and other dietary requirements, it’s also not uncommon for someone to restrict or eliminate certain foods.

But these behaviours may also be the sign of an unhealthy relationship with food. You can have a problematic pattern of eating without being diagnosed with an eating disorder.

So, where’s the line? What is disordered eating, and what is an eating disorder?

What is disordered eating?

Disordered eating describes negative attitudes and behaviours towards food and eating that can lead to a disturbed eating pattern.

It can involve:

  • dieting

  • skipping meals

  • avoiding certain food groups

  • binge eating

  • misusing laxatives and weight-loss medications

  • inducing vomiting (sometimes known as purging)

  • exercising compulsively.

Disordered eating is the term used when these behaviours are not frequent and/or severe enough to meet an eating disorder diagnosis.

Not everyone who engages in these behaviours will develop an eating disorder. But disordered eating – particularly dieting – usually precedes an eating disorder.

What is an eating disorder?

Eating disorders are complex psychiatric illnesses that can negatively affect a person’s body, mind and social life. They’re characterised by persistent disturbances in how someone thinks, feels and behaves around eating and their bodies.

To make a diagnosis, a qualified health professional will use a combination of standardised questionnaires, as well as more general questioning. These will determine how frequent and severe the behaviours are, and how they affect day-to-day functioning.

Examples of clinical diagnoses include anorexia nervosa, bulimia nervosa, binge eating disorder and avoidant/restrictive food intake disorder.

How common are eating disorders and disordered eating?

The answer can vary quite radically depending on the study and how it defines disordered behaviours and attitudes.

An estimated 8.4% of women and 2.2% of men will develop an eating disorder at some point in their lives. This is most common during adolescence.

Disordered eating is also particularly common in young people with 30% of girls and 17% of boys aged 6–18 years reporting engaging in these behaviours.

Although the research is still emerging, it appears disordered eating and eating disorders are even more common in gender diverse people.

Can we prevent eating disorders?

There is some evidence eating disorder prevention programs that target risk factors – such as dieting and concerns about shape and weight – can be effective to some extent in the short term.

The issue is most of these studies last only a few months. So we can’t determine whether the people involved went on to develop an eating disorder in the longer term.

In addition, most studies have involved girls or women in late high school and university. By this age, eating disorders have usually already emerged. So, this research cannot tell us as much about eating disorder prevention and it also neglects the wide range of people at risk of eating disorders.

Is orthorexia an eating disorder?

In defining the line between eating disorders and disordered eating, orthorexia nervosa is a contentious issue.

The name literally means “proper appetite” and involves a pathological obsession with proper nutrition, characterised by a restrictive diet and rigidly avoiding foods believed to be “unhealthy” or “impure”.

These disordered eating behaviours need to be taken seriously as they can lead to malnourishment, loss of relationships, and overall poor quality of life.

However, orthorexia nervosa is not an official eating disorder in any diagnostic manual.

Additionally, with the popularity of special diets (such as keto or paleo), time-restricted eating, and dietary requirements (for example, gluten-free) it can sometimes be hard to decipher when concerns about diet have become disordered, or may even be an eating disorder.

For example, around 6% of people have a food allergy. Emerging evidence suggests they are also more likely to have restrictive types of eating disorders, such as anorexia nervosa and avoidant/restrictive food intake disorder.

However, following a special diet such as veganism, or having a food allergy, does not automatically lead to disordered eating or an eating disorder.

It is important to recognise people’s different motivations for eating or avoiding certain foods. For example, a vegan may restrict certain food groups due to animal rights concerns, rather than disordered eating symptoms.

What to look out for

If you’re concerned about your own relationship with food or that of a loved one, here are some signs to look out for:

  • preoccupation with food and food preparation

  • cutting out food groups or skipping meals entirely

  • obsession with body weight or shape

  • large fluctuations in weight

  • compulsive exercise

  • mood changes and social withdrawal.

It’s always best to seek help early. But it is never too late to seek help.

‘Do not eat’: what’s in those little desiccant sachets and how do they work?

Source: The Conversation – Canada – By Kamil Zuber, Senior Industry Research Fellow, Future Industries Institute, University of South Australia

When you buy a new electronic appliance, shoes, medicines or even some food items, you often find a small paper sachet with the warning: “silica gel, do not eat”.

What exactly is it, is it toxic, and can you use it for anything?

The importance of desiccants

That little sachet is a desiccant – a type of material that removes excess moisture from the air.

It’s important during the transport and storage of a wide range of products because we can’t always control the environment. Humid conditions can cause damage through corrosion, decay, the growth of mould and microorganisms.

This is why manufacturers include sachets with desiccants to make sure you receive the goods in pristine condition.

The most common desiccant is silica gel. The small, hard and translucent beads are made of silicon dioxide (like most sands or quartz) – a hydrophilic or water-loving material. Importantly, the beads are porous on the nano-scale, with pore sizes only 15 times larger than the radius of their atoms.

Silica gel looks somewhat like a sponge when viewed with scanning electron microscopy.
Trabelsi et al. (2009), CC BY-NC-ND

These pores have a capillary effect, meaning they condense and draw moisture into the bead similar to how trees transport water through the channelled structures in wood.

In addition, sponge-like porosity makes their surface area very large. A single gram of silica gel can have an area of up to 700 square metres – almost four tennis courts – making them exceptionally efficient at capturing and storing water.

Is silica gel toxic?

The “do not eat” warning is easily the most prominent text on silica gel sachets.

According to health professionals, most silica beads found in these sachets are non-toxic and don’t present the same risk as silica dust, for example. They mainly pose a choking hazard, which is good enough reason to keep them away from children and pets.

However, if silica gel is accidentally ingested, it’s still recommended to contact health professionals to determine the best course of action.

Some variants of silica gel contain a moisture-sensitive dye. One particular variant, based on cobalt chloride, is blue when the desiccant is dry and turns pink when saturated with moisture. While the dye is toxic, in desiccant pellets it is present only in a small amount – approximately 1% of the total weight.

Desiccants come in other forms, too

Apart from silica gel, a number of other materials are used as moisture absorbers and desiccants. These are zeolites, activated alumina and activated carbon – materials engineered to be highly porous.

Another desiccant type you’ll often see in moisture absorbers for larger areas like pantries or wardrobes is calcium chloride. It typically comes in a box filled with powder or crystals found in most hardware stores, and is a type of salt.

Kitchen salt – sodium chloride – attracts water and easily becomes lumpy. Calcium chloride works in the same way, but has an even stronger hygroscopic effect and “traps” the water through a hydration reaction. Once the salt is saturated, you’ll see liquid separating in the container.

Closet and pantry dehumidifiers like this one typically contain calcium chloride which binds water.

I found something that doesn’t seem to be silica gel – what is it?

Some food items such as tortilla wraps, noodles, beef jerky, and some medicines and vitamins contain slightly different sachets, labelled “oxygen absorbers”.

These small packets don’t contain desiccants. Instead, they have chemical compounds that “scavenge” or bond oxygen.

Their purpose is similar to desiccants – they extend the shelf life of food products and sensitive chemicals such as medicines. But they do so by directly preventing oxidation. When some foods are exposed to oxygen, their chemical composition changes and can lead to decay (apples turning brown when cut is an example of oxidation).

There is a whole range of compounds used as oxygen absorbers. These chemicals have a stronger affinity to oxygen than the protected substance. They range from simple compounds such as iron which “rusts” by using up oxygen, to more complex such as plastic films that work when exposed to light.

Some of the sachets in your products are oxygen absorbers, not desiccants – but they may look similar.

Can I reuse a desiccant?

Although desiccants and dehumidifiers are considered disposable, you can relatively easily reuse them.

To “recharge” or dehydrate silica gel, you can place it in an oven at approximately 115–125°C for 2–3 hours, although you shouldn’t do this if it’s in a plastic sachet that could melt in the heat.

Interestingly, due to how they bind water, some desiccants require temperatures well above the boiling point of water to dehydrate (for example, calcium chloride hydrates completely dehydrate at 200°C).

After dehydration, silica gel sachets may be useful for drying small electronic items (like your phone after you accidentally dropped it into water), keeping your camera dry, or preventing your family photos and old films from sticking to each other.

This is a good alternative to the questionable method of using uncooked rice, as silica gel doesn’t decompose and won’t leave starch residues on your things.

Qu’est-ce que le paiement pour service environnemental ?

Ils rémunèrent des personnes ou des entreprises pour un certain usage des terres que l’on associe, à tort ou à raison, à une amélioration des services écosystémiques. IZE-5tyle/Shutterstock

Le paiement pour services environnementaux ou PSE est, selon sa définition officielle, un instrument économique pour l’environnement consistant en la rémunération d’une personne ou d’une organisation qui rend un service environnemental. Un dispositif de ce type a été créé par le gouvernement français, notamment à destination des agriculteurs. L’objectif : rémunérer les pratiques vertueuses contribuant à maintenir et à restaurer les services écosystémiques dont bénéficie toute la société.


D’ici le 1er septembre 2026, tous les États membres de l’Union européenne doivent élaborer leur plan de restauration de la nature. Il vise à enrayer l’érosion de la biodiversité et à revitaliser les écosystèmes sur l’ensemble du territoire. Une action politique qui met en lumière la notion de paiement pour service environnemental.

Les services environnementaux sont rendus à d’autres humains – où qu’ils soient dans le temps et l’espace – à travers une action intentionnelle visant à préserver, restaurer ou augmenter un service écosystémique. Un agriculteur qui stoppe l’usage de pesticides ou créé des îlots de plantes mellifères fournit un service environnemental qui va favoriser le service écosystémique de pollinisation rendu par les abeilles.

Quant aux services écosystémiques, ils sont définis par le Millenium Ecosystem Assessment comme « les bénéfices directs et indirects que les hommes retirent de la nature ». Certains insectes apportent un service de pollinisation, une formation végétale apporte des bénéfices en termes de régulation du ruissellement et de fixation du carbone.

Alors faut-il parler de paiements pour services écosystémiques ou pour services environnementaux ?

Service écosystémique et environnemental

Si l’on se réfère aux travaux de l’évaluation française des écosystèmes et services écosystémiques (EFESE), il est plus logique de parler de paiements pour services environnementaux. L’EFESE distingue clairement deux notions :

  • Service écosystémique : fonction d’un écosystème dont l’utilisation permet de retirer un avantage – pour l’agriculteur, ou de manière plus générale pour la société.

  • Service environnemental : action ou mode de gestion d’un acteur, comme un agriculteur, qui améliore l’état de l’environnement en permettant l’augmentation d’un service écosystémique.

Fonctionnement type d’un paiement pour service environnemental.
Banque des territoires

Muradian et ses collègues envisagent les paiements pour service environnemental comme « des transferts de ressources entre des acteurs sociaux, dans le but de créer des incitations pour aligner les décisions individuelles et/ou collectives quant à l’usage des sols avec l’intérêt social concernant la gestion des ressources naturelles ». Ils rémunèrent des personnes ou des entreprises pour un certain usage des terres que l’on associe, à tort ou à raison, à une amélioration des services écosystémiques.

Sept points clés

Nous pouvons caractériser les paiements pour service environnemental à travers sept points clés :

  • Paiements directs : les paiements sont effectués directement aux prestataires de services environnementaux, souvent par le biais d’un intermédiaire comme un programme. Les bénéficiaires sont les usagers du foncier et des ressources dont les pratiques ont un impact direct sur les services écosystémiques. Les paiements peuvent être en argent, sous forme d’investissements ou de services, comme la sécurisation foncière. Le montant des paiements peut être négocié ou, le plus souvent, faire l’objet d’un barème fixé par le programme.

  • « Bénéficiaire-payeur » : les bénéficiaires directs ou indirects des services environnementaux – individus, communautés, entreprises, ou institutions agissant au nom de l’intérêt général – paient pour ces services.

  • Caractère volontaire et contractuel : les bénéficiaires des paiements adhèrent librement au programme à travers des accords contractuels qui les engagent pour une certaine durée. Mais le financement des PSE n’est pas forcément volontaire et peut être contraint (renchérissement des factures d’eau, redevances sur différents produits ou services, impôt).

  • Conditionnalité : les paiements dépendent de la fourniture continue des services environnementaux, au sens du respect des obligations contractuelles. Les paiements sont généralement basés sur la mise en œuvre de pratiques de gestion dont les parties conviennent contractuellement qu’ils sont susceptibles de donner lieu à ces avantages.

  • Ciblage : En général, les PSE sont concentrés sur certaines zones d’importance écologique et/ou menacée (ciblage géographique). Le ciblage social, c’est-à-dire le fait de réserver l’offre de PSE aux producteurs à faibles revenus ou à des populations autochtones, est moins pratiqué. Toutefois, quand les paiements se font sur une base surfacique, les montants versés sont souvent plafonnés ou dégressifs à partir d’un seuil de surface.

  • Additionnalité : les paiements sont effectués pour des actions qui vont au-delà de celles que les gestionnaires des terres accompliraient même en l’absence de paiements. Cette condition est controversée, car elle risque d’exclure des bénéfices des PSE des populations ou des producteurs aux pratiques déjà écologiquement vertueuses. En pratique, elle est rarement appliquée du fait des coûts de vérification, par rapport à un scénario business-as-usual. Il en va de même pour l’additionnalité légale. On ne devrait pas, en principe, rémunérer pour empêcher des pratiques déjà prohibées par les règlements, mais beaucoup de programmes de PSE le font néanmoins pour faciliter l’application des lois.

  • Sécurité foncière : un titre de propriété n’est pas une condition sine qua non. Les bénéficiaires des paiements doivent disposer au minimum d’un « droit d’exclusion » et de droits de gestion sur la terre dont ils sont les usagers.
