In the centre of Kathmandu valley, the Bagmati River flows from the hills of Shivapuri, passing through the UNESCO World Heritage Site Pashupatinath Temple on its way to India’s holy river Ganga. For decades, the water of the Bagmati uplifted many livelihoods. However, with rapid urbanisation and industrialization, the once holy river is now the most polluted river of Nepal.

Understanding the Significance of the Bagmati River

The Bagmati River originates from the Bagdwar area in the Shivapuri Hills, located in the northwestern part of Kathmandu Valley, central Nepal, at an elevation of around 2,690 metres (8825 feet) above sea level.

The river is a complex system composed of seven tributaries (Bagmati, Bishnumati, Dhobikhola, Manohara, Nakkhu, Balkhu, and Tukucha) and five sub-tributaries (Godavari, Hanumante, Sangla, Mahadev, and Kodku Khola).

As the oldest river of Nepal, Bagmati is considered sacred by Hindus, and holds divine power, acting as the foundation of Kathmandu civilization. The river and its tributaries support around 3 million people in and around Kathmandu Valley, who use its waters for crop farming, fishing, laundry, household tasks, and bathing.

The Bagmati also flows through one of the most significant Hindu temples in the world, the Pashupatinath Temple, a UNESCO World Heritage Site. The river unites many ethnic groups and tourists under a common set of religious customs and plays a significant role in religious and cultural celebrations. Pashupati Aryaghat, a cremation place located on the riverbanks near the temple, is one of Nepal’s most famous open-air cremation sites.

Unfortunately, the river has reached alarming levels of pollution, posing significant threats to the environment, public health, and even cultural heritage. Over the years, industrial waste, untreated sewage, and rampant human activities have turned this once-pristine river into a symbol of environmental degradation. 

Causes of River Pollution

Pollution in the Bagmati is an uphill battle for the sustainable development of the Kathmandu Valley.

1. Industrial and Domestic Discharge

Rapid industrialization along the riverbanks has led to the unregulated discharge of untreated hazardous chemicals, minerals, high quantities of oxygen-demanding wastes, and synthetic organic compounds. In the Kathmandu Valley, industrial wastewater accounts for 7% of the total wastewater, while domestic wastewater contributes the remaining 93%. 

A 2011 report published by the High Powered Committee for Integrated Development of Bagmati Civilization (HPCIDBC) found that more than 90% of households in the Kathmandu Valley have access to toilet facilities; the concerning reality, however, is that the majority of wastewater is being discharged directly into the rivers due to the absence of suitable and sufficient treatment systems.

2. Untreated Sewage

The discharge of untreated domestic sewage from residential areas, slums, and urban settlements is a major contributor to river pollution. Over 95% of wastewater is estimated to have been released into the water bodies without treatment.

Estimates for 2020 and 2030 based on 2014 values revealed that the existing and rehabilitated wastewater treatment plants would still be insufficient to alleviate Bagmati pollution. The 2020 projection was already exceeded in values by 2019. 

3. Solid Waste Mismanagement

Improper solid waste management practices, such as open dumping and littering, result in the accumulation of non-biodegradable materials along the riverbanks. Solid waste such as plastics, paper and paper products, textiles, rubbers and leathers, metals, glass, and organic waste pose a significant threat to aquatic life and the overall ecosystem of the river. Estimates suggest that over 60% of the solid trash in the Kathmandu valley is dumped on the road or nearby river banks, with almost 25% of the total reaching open waters. A 2015 research found that an average of about 70,000 plastic fragments (micro- and macro-) travel through Kathmandu Valley along the Bagmati river each day. 

4. Religious Practices

As mentioned previously, the Bagmati holds immense religious significance, attracting pilgrims who perform rituals and ceremonies. Hindus in Kathmandu regularly gather around the river to pray at shrines and celebrate holidays and festivals. For example, during the Rishi Panchami holiday, women enter the river to wash away their sins, while during the Bala Chaturdashi festival, hundreds hold ceremonies for the salvation journey of the deceased members of family and society.

With an average of 37 cremations per day, the Pashupatinath Temple is the largest cremation site in Nepal. The bodies are burnt along the banks of the river while the remaining ashes are thrown into the water. The improper disposal of religious offerings, such as flowers, garlands, and other items only adds to the pollution burden.

Consequences 

The Kathmandu Valley has become densely populated over the last few decades due to rapid urbanisation, with an annual population growth rate of 5.2%. Unfortunately, the worsening water conditions and the continued discharge of untreated industrial and domestic waste into the river are hindering the sustainable development of Kathmandu and other urban areas in the valley, degrading the region’s environment. 

River pollution is also linked to adverse health issues, particularly arising from the consumption of contaminated water. According to the World Health Organization (WHO), around one million people die each year globally from preventable conditions such as diarrhoea as a result of unsafe drinking-water, poor sanitation and hand hygiene. In Nepal, the mortality rate due to unclean water, poor sanitation and hygiene is 17.8 per 100,000 people. Even though 2.7% of the Earth’s freshwater is found in Nepal, its most developed part, Kathmandu, faces acute water scarcity. 

To tackle the problem, the Nepali government has taken several initiatives to establish drinking water arrangements, such as the Pani Goswara water supply system in May 1973, which was handed over to the Nepal Water Supply Corporation in 2013. In 2008, the Kathmandu Valley Water Supply Management Board (KVWSMB) granted Kathmandu Upatyaka Khanepani Limited (KUKL) a 30-year licence to provide water supply and sanitation services. Through the Melamchi Water Supply Project, approved by the Asian Development Bank in 2000, the 1.5 million residents (180,000 households) of the Kathmandu Valley long-awaited improvement of water supply services were carried out, leading to better water quality, increased quantity, improved supply, extended service areas, more equitable water distribution, and better customer services. 

Despite all this, water shortages in the Kathmandu Valley still persist today due to overuse of groundwater reserves and river pollution. On top of this, traditional water sources have also dried up for a variety of reasons, including overpumping of groundwater, shrinking open spaces, prolonged drought conditions, black-topping, and concretization of roads and open spaces around homes, leaving only a few functional taps and thus forcing people to either queue for water or purchase it from private sources such as water tankers. 

One-quarter of the drinking water samples collected by the government’s Epidemiology and Disease Control Division in Kathmandu in 2023 tested positive for faecal coliform. The test was carried out on jar water, tap water supplied by the state, tanker water, tube well water, water from wells, and water from the Melamchi river, proving that most water sources in the region are contaminated. 

Towards a Solution?

There have been growing efforts for river pollution management over the years. Five Wastewater Treatment Plants (WWTP) were constructed in the 1980s to mitigate pollution in the water and improve health and sanitation problems in the Kathmandu Valley. The Kathmandu Valley Wastewater Management Project (KVWMP), launched in 2013 with the support of the Asian Development Bank (ADB), has contributed to expanding and rehabilitating these wastewater treatment plants. Since the 1990s, Nepal has also started introducing constructed wetlands (CWs) to treat wastewater using wetland plants, soils, and related microorganisms. 

In 2011, with the support of the ADB, the Nepali government proposed the Bagmati River Basin Improvement Project (BRBIP) to increase flow augmentation in the Bagmati river during the dry season and wash away wastewater discharges. This included the expansion of the Dhap Dam to store monsoon rainfall and release it downstream during the non-monsoon season, which officially began operating in 2023. As part of the project, construction works for a new dam, the Nagmati Dam, have also begun. Expected to be completed by 2032, the reservoir will store 9.4 billion litres of monsoon runoff and will be releasing 450 l/s into the Bagmati River.

Nevertheless, critics of the project pointed out that more than 80,000 trees will be cut down to make space for the Nagmati Dam, with severe repercussions on ecosystems of the area. According to a 2022 study on Groundwater for Sustainable Development, construction of these dams will disrupt the natural flow and impact the ecosystem’s biological and chemical properties. Moreover, some argue that the project will not lead to the hoped-for results. In an editorial for the Nepali Times, Ramesh Kumar wrote, “When released in the dry season, the stored water is supposed to wash away the waste, flush the stench of sewage, and raise the level of the aquifer. However, no amount of water released into the Bagmati will clean it as long as it continues to be a sewage canal and a dumping ground for solid waste.”

In the past years, local governments, environmental NGOs and various international organisations also promoted an array of cleanup campaigns and projects. One such example is the Bagmati River Clean-up Mega Campaign (2013), which successfully removed over 20,000 metric tonnes of waste by its eleventh year.

Despite these mega projects to revive the river, water quality remains a health hazard for nearby communities. 

Findings published in the Journal of Nepal Health Research Council (2023) found 615 coliform bacteria at 26 out 66 sites along the Bagmati River, with 241 highly resistant to penicillin, erythromycin, and tetracycline antibiotics. Similarly, bacteriological analysis published in 2023 by another group of researchers also reveals that the Bagmati River is highly contaminated with different microorganisms, with nearly 80% found to be resistant to multiple classes of antibiotics. The presence of antibiotic-resistant bacteria suggests the ongoing practice of raw sewage discharge, open defecation, and solid waste dumping along the river banks. 

In 2024, Madhukar Upadhya, a senior watershed expert, said it is uncertain if it is possible to restore the Bagmati river without a holistic approach. Upadhya argued that constructing structures without proper studies of their risks is not cost-effective and only involving local communities in these projects will lead to better results.

Final Thoughts

Like the Ganga in India, Nepal’s Bagmati River is a sacred body of water with cultural and spiritual importance. Given that adjacent nations such as India and Pakistan have some of the most poisonous rivers in South Asia, a collaborative research and development team could be a viable, cost-effective, and efficient option. If these issues remain unaddressed, river pollution will continue to harm natural biodiversity, people’s health, and slow down sustainable development in the region. Urgent and coordinated efforts are needed to mitigate pollution sources, improve waste management practices, and raise public awareness.

In an ever-changing world where consumerism and mass production define the majority of the societies, are examples of the tragedy of the commons.  Many countries are facing several environmental problems, such as outdoor air pollution, plastic pollution, and food waste. Ecovillages, on the other hand, provide promise for sustainable living in the face of increasing urbanisation. This article examines ecovillages from across the globe where people live as a community with a laid-back approach practising eco-friendly lifestyle. 

What Is an Ecovillage? 

There is no one-size-fits-all definition of an ecovillage since each community has a distinct vision, mission, culture, environment, and interest. The Global Ecovillage Network (GEN) defines ecovillage as an intentional, traditional or urban community that aims to become socially, culturally, ecologically, and economically sustainable using locally owned participatory processes. Ecovillages aim to minimise the environmental and social impacts, and influence others through their model and collaboration. 

Generally speaking, traditional ecovillages are existing rural villages and communities that have decided to determine their own future path by combining life-sustaining traditional wisdom with positive new innovation through participatory methods, whereas intentional ecovillages are formed when individuals with the same goal or vision bond together.

The GEN was founded in 1995 by 25 community representatives from around the world to establish a solid international network of ecovillage communities and to reach out to policymakers, NGOs, academics, and governments. 

At present, there are over 1,100 villages worldwide. These dwellings consist of a population size of 50-350 people living in a sustainable environment. The primary motive of this lifestyle is to seek alternatives to modern lifestyles, including a secure environment, better childcare facilities, improved services, communal enjoyment, environmental preservation, urban sprawl reduction, and local economic development. Depending on an individual’s motivation and the community’s objectives, one may be admitted or rejected.

Ecovillages Around the World

The following are the 5 interesting ecovillages from around the world listed by the World Economic Forum

1) Findhorn Ecovillage, Scotland

Since its establishment in 1985 in Moray, Scotland, Findhorn Ecovillage has become the oldest and most well-known intentional ecovillage in the world. Its founders, who were involved in the GEN, became pioneers of the ecovillage movement. 

The “living laboratory” ecovillage, which was designated the “Best Practice Design” as a model for holistic and sustainable living by the United Nations Centre for Human Settlements in 1998, is inspired by the concept of a locally-engaged and low-carbon lifestyle, emphasising the connections between the social, spiritual, economic, and ecological aspects of life. Owing to the unique model where all required things are within a 20-minute walk, this Scottish ecovillage produces one of the lowest ecological footprints of any community in the developed world, nearly half of the UK average. According to a 2006 report, the total Findhorn Ecovillage ecological footprint was 3.86 global hectares (gha) per person, whereas the UK’s was 5.4 global hectares (gha) per person.

Sustainable architecture is at the forefront of Findhorn’s ecological conscience. For instance, buildings have passive solar features, breathing walls which allow controllable flow of air and vapour, efficient heating systems and insulation, water conserving technology, and are built with sustainable materials, such as natural clay and recycled car tires. It also has a biological wastewater treatment plant – the so-called “living machine” – which treats the sewage of up to 500 people living in the community, and people drive zero-emissions electric vehicles. Four community-owned wind turbines supply more than enough the energy needed by the community.

Findhorn provides programmes to raise awareness about sustainability among visitors and the public, such as offering permaculture design certificate courses and ecovillage experience weeks. It also hosts the Findhorn International Forum on Sustainability, which allows participants to interact with representatives from businesses, NGOs, social enterprises and organisations, empowering them to generate new perspectives on existing environmental challenges.

2) Eco Truly Park, Peru

Located on the Peruvian Pacific coast, Eco Truly Park is a renowned ecovillage consisting of 18 conical houses. Its members live in artistic, self-sustaining, and spiritual ways, inspired by the Indian Vaishnava practice of living a healthy, yogic, simple and thoughtful life. Caring for the land is the cornerstone of daily health and vegetarian food is the main diet, as the community emphasises its impact on the health and environment.

Eco Truly Park hosts tours, workshops and volunteer programs where participants can learn about organic farming techniques, harvest vegetarian food, and can take art, yoga, and philosophy classes that teach them principles of non-violence and respect for nature. More than 75,000 visitors have come since its opening in 1994

3) The Farm, Tennessee, United States

Stephen Gaskin, a Marine combat veteran and hippie guru, as described by the New York Times, founded The Farm Community in 1971 in Tennessee along with 300 spiritual seekers. Established on the ground of nonviolent values, vegetarianism, and environmental stewardship, it is the oldest intentional ecovillage in the US and currently counts around 200 members and residents. 

The Farm follows eco-friendly practices including sustainable farming, composting, and green energy. Community building is prioritised when it comes to making a positive impact through collaboration and harmony. The ecovillage offers a number of well-known services, such as midwifery centres with workshops, an international development and relief nonprofit, and the Swan Conservation Trust

It also has the Ecovillage Training Center, started in 1994 to teach students about permaculture, organic certification professions, green building, renewable energy, installing solar electricity and water heating, and other lessons of eco-living.

4) Crystal Waters Eco Village, Australia

Started in 1987 as the first intentional permaculture village in the world, today Crystal Waters Eco Village has 250 residents from different backgrounds. The 640-acre bushland – recognised as  “Land for Wildlife” – is home to dozens of birds, kangaroos, frogs, and wallabies. Residents occupy 20% of the land, while the remaining 80% is available to be licensed for agricultural, forestry, recreation, and habitat projects.

This ecovillage is inspired by values of clean air, water and soil; the freedom of spiritual belief; meaningful social interaction among their members; and safe and healthy accommodation. It is also based on permaculture, a concept established by Bill Mollison, which in his book “Introduction to Permaculture” defines it as interacting with nature, observing plants and animals holistically, and treating each area as a whole system rather than a single product. 

Some examples of permaculture incorporated at Crystal Waters Eco Village include maintaining the quality and quantity of water downstream, efficient use of multi-functional dams (emergency water, a flood mitigation strategy, etc), widespread use of recycle and reuse practices and of environmentally-friendly building materials, and effective use of land (accommodation, agriculture, forestry, etc). They also provide a permaculture school where participants can learn technical skills as well as the theory behind permaculture.

5) EcoVillage, New York, United States

Founded in 1991 in Ithaca, New York, the EcoVillage is part of an international coalition aiming to strive innovative responses to social, environmental, and economic problems. Nowadays, the ecovillage is one of the biggest co-housing communities in the world, with 170 adults and 40 children across 3 neighbourhoods: Frog, Song, and Tree. 

The buildings are built with passive solar design for natural heating and cooling, and some have photovoltaic panels for solar power.The Tree neighbourhood is designed using passive house principles, meaning houses have large, South-facing windows that heat up the environment easily through the natural daylight, whereas windows are kept at minimum in the North side to keep frigid winds at bay. These houses are highly insulated, with tight air-sealing and thick walls.

This village follows a co-housing model of community-oriented living, with automobiles parked outside the neighbourhood, paths connecting residences, and communal spaces utilised for community meals, play areas, and classes. Organic farms on site provide fruits and vegetables to its members. A 2014 research found that the village ecological footprint is 70% lower than average Americans.

EcoVillage also provides an education program called Thrive. It offers interested individuals a wide range of learning opportunities on sustainable living, such as in-person tours of green building as well as workshops on green energy, environmentally friendly food and farming, land conservation. It also offers online programs such as talks on sustainability and mindfulness by village residents and conscious communication workshops. 

Visitors can also engage in forest bathing walks, which have both physical and mental health benefits and are found to be effective in lowering blood pressure, boosting creativity, improving eye problems caused by the prolonged use of electronic gadgets as well as improving mental well-being.

Conclusion

Amidst the hustle and bustle of city life, learning about different ecovillages from different countries give us hope for a more sustainable and livable future. These communities try to balance between economic development, environmental protection, and social well-being. The model can be a lesson for many countries since all four aspects, social, cultural, ecological, and economic are taken into consideration to promote environmental protection, social cohesion, and individual well-being. 

Changing the world takes everyone’s cooperation, understanding, and efforts to preserve nature while focusing on present development, without jeopardising future generations’ ability to meet their own. After all, this is sustainable development.

The growing popularity of Mount Everest has resulted in various forms of pollution spoiling the fragile ecosystem of the region. This article delves into the root causes of pollution on Mount Everest and addresses the need for responsible tourism and sustainable practices to mitigate the issue.

Background

Mount Everest, located in the Mahalangur Himal sub-range of the Himalayas in Nepal, is the world’s highest mountain, reaching an elevation of 8,850 metres above sea level. Since the first climbers summit Everest in 1953, New Zealand mountaineer Edmund Hillary and Tibetan guide Tenzing Norgay, climbing the mountain has become a popular expedition for hiking enthusiasts around the world. 

There has been a significant surge in the number of tourists and mountaineers visiting the Sagarmatha National Park, which is home to Mount Everest. According to official data published in 2021, mountain expeditions experienced an upward trend, from 3,600 in 1979 to more than 58,000 tourists in 2019.

Traditionally, conquering Everest’s summit required mountaineering skills and physical endurance levels that require years of practice and experience. After all, climbing Everest is a potentially deadly activity, with life-threatening risks such as hypothermia, frostbite, avalanches, and deadly altitude sickness. 
Today, the situation is different. Unlike in the past, with the commercialization of mountaineering, climbers who pay expedition fees that can range anywhere between US$32,000 and $200,000 can attempt to reach the summit. 2023 saw a record high climbers, with authorities issuing a total of 463 permits.

Increasing Pollution

The exponential rise in tourism has led to significant issues in the region, particularly related to pollution. 

1) Dead Bodies

Between 1990 and 2019, more than 300 people have lost their lives in an attempt to set foot on Everest. On average, six people die every year while ascending and descending the peak. 2023 had the record high death toll, with at least 12 climbers dead and an additional five either missing or assumed dead. 

Oftentimes, bodies are never found or retrieved due to the mountain’s extreme climate and the logistical challenges it poses. Carrying these bodies back to the base camp is not only challenging but also potentially fatal for rescue teams.

For this reason, many bodies are left behind. According to a 2015 investigation by the British Broadcasting Corporation (BBC), Everest’s slopes are currently home to more than 200 corpses

2) Human Excrement 

A lack of solid waste management system means that streams of human excrement are circulated by the glaciers up in the mountain on a regular basis. Although local climbers are employed to haul the human waste down from Everest base camps in barrels to dispose into landfills near the village of Gorak Shep, the waste often gets washed downstream, especially during the summer monsoon season. 

Mountain geologist Alton Byers estimated that approximately 5,400 kilograms of human waste is collected from the base camps each year. While this number accounts for the collected dumping, one can step out of the base camp tents, and still stand on minefields of human excrement

Every year, human excrement has been a rapidly worsening problem in the Sagarmatha National Park through a combination of inaction and ineffective measures. Some climbers defecate in biodegradable bags, which, however, are said to be expensive, while others dig holes, which eventually emerge back to the surface as temperatures in the region keep rising, melting the ice cover. The South Col Glacier, which sits between Mount Everest and Lhotse at around 7,906m (25,938 ft) above sea-level, has lost more than 180ft (54m) of thickness in the last 25 years

As human excrement leak to the Base Camp or Sherpa communities, they contaminate the landscape and can result in lower-intestinal and upper-respiratory infections as well as waterborne diseases such as cholera and hepatitis A among climbers and local communities.

3) Solid Waste

High-altitude expeditions require investment of pricey life supporting equipment, including tents, ropes, portable gas stoves, ladders, tins, and cans. All this contributes to waste issues, with Earth’s highest point estimated to be covered in around 30 tonnes of garbage.

An assessment on stream water and snow samples from Mount Everest conducted between April and May 2019 found that microplastics are omnipresent in all collected snow samples, with the highest concentration of microplastics found at Everest Base Camp. Microplastics found in 53 out of 56 snow samples were linked to fibres from outdoor clothing. Particularly polyester was the most prevalent polymer detected in both snow and stream samples (56%), followed by acrylic (31%), nylon (9%), and polypropylene (5%). The study concluded that microplastics are likely from clothing and equipment used by the climbers and trekkers.

Are Authorities Doing Enough? 

To combat solid waste generated by climbers, the government of Nepal in 2014 implemented a deposit scheme requiring all summiteers to deposit US $4,000 prior to the expedition. In order to get the money back, they are required to return to the Base Camp with at least 8 kilograms of waste each, the average amount estimated to be produced by an individual during the expedition.

The Nepali government also frequently mobilises its army to go on cleanup expeditions to Mount Everest. For example, in 2019, along with non-governmental organisations, the Nepali army collected over 2 tonnes of waste, and in 2023, the army-led Mountain Clean-up Campaign collected 35 tonnes of waste on four mountains including Mt. Everest, Mt. Lhotse, Mt. Annapurna, and Mt. Baruntse. 

Several non-governmental organisations and private companies are also leading and organising campaigns to clean-up and to educate climbers and local communities on the importance of solid waste management.

One such exemplary organisation is the Sagarmatha Pollution Control Committee (SPCC), established in 1991 to promote environmental sustainability through the development of sustainable waste management infrastructure and educate the local community on the 3Rs: reducing, reusing, and recycling. Another organisation aiming to tackle the human waste crisis in the region is the Mount Everest Biogas Project, which is building a solar-powered biogas system powered by human waste to supply local communities with sustainable fuel. 

Suggestions

Though governmental, non-governmental and private organisations have worked collaboratively to manage the waste pollution, it is important to note that so have the number of climbers over the decades. Waste management and waste reduction practices alone are not enough, especially in pristine places like Everest, because they fail to address the crux of the problem. 

The regulatory measures for Everest expeditions in Nepal pale in comparison to what other countries are doing in terms of strengthening control over expedition formation, flow of expedition traffic, security arrangements, and environmental protection.

A great example of this is China. Here, expedition organisers who meet standards set by China Tibet Mountaineering Association will get preference over others. What’s more, mountaineering teams qualified to climb the Everest from Nepal route are not allowed to climb from Tibet. In regards to traffic control, China only issues 300 climbing permits to foreigners annually. Security-related provisions in the country include one guide for each summit climber, and foreign tourists are not allowed to go on solo climbs, a rule that Nepal introduced just last year

The Nepali government should prioritise accountability and supervision on perpetrators by implementing measures similar to those in place in China. Moreover, sustainable approaches in terms of sustainable climbing clothes and equipment should be promoted. Last but not the least, the local community and visitors should be educated on practical and sustainable lifestyle choices to encourage proper disposal in designated places. 

Final Thoughts

Since Nepal’s economy heavily relies on tourism, the degradation of the region’s environment can exacerbate existing problems, leading to a grim future for the land-locked country. The ecological damage Mount Everest is enduring due to climate change is further exacerbated by tourists’ littering, microplastic pollution, and human waste. As Terry Swearingen, Winner of Goldman Environmental Prize in 1977, once said, “We are living on this planet as if we had another one to go to.” 

It is true that the popularity of mountaineering gave a way of life that shaped locals’ livelihood, from employment opportunities to renown world record holders. Nevertheless, if we want to keep selling the Everest dream, we have to work more proactively to protect it.

According to the European Commission, human-caused global warming is now growing at a pace of 0.2C every decade. Behavioral nudges may be the most effective ways to draw an individual’s attention towards the climate crisis and promote sustainable choices. Besides being low-cost and salient, the use of various types of prompts, ranging from texts to visual stimuli, makes it attractive, too. By leveraging these nudges, policymakers, organisations, and even individuals can promote sustainable behaviours to all walks of life without resorting to mandates or restrictions. This article explores the power of choice architecture in encouraging sustainable choices and their potential to drive positive environmental change.

Understanding Behavioral Nudges

Behavioral nudges are subtle changes to the choice architecture that can influence people’s decisions without limiting their freedom of choice. These nudges work by directing individuals towards choices that are in their best interests or align with desired outcomes. 

In their book Nudge, co-authors Richard Thaler and Cass R. Sunstein explain that people typically think in two cognitive systems: System 1 and System 2. System 1 is an automatic thought process, whereas system 2 is a reflective thought process. For example, the automatic system is a gut feeling and the reflective system is thinking critically. 

Understanding how to differentiate between these types allows policymakers to propose nudges that can be optimised to achieve their full potential.

How to Nudge Effectively

According to the UN Environment Programme’s (UNEP) Little Book of Green Nudges, four aspects are crucial when designing a nudge to achieve the full effectiveness:

  1. Easy: Humans tend to opt for easy options, meaning that, in order to encourage desired behaviors, any barriers or hassles have to be removed. Alternatively, we can simply set a default option to achieve the expected outcome. 
  1. Attractive: People are more likely to get magnetised by visually attractive cues and try to develop a behavior. These cues can be noticeable, and can be made motivating to draw positive results. 
  1. Social: People are greatly influenced by their peers. Hence, a way to encourage them to practise environmentally friendly behaviors is by promoting the fact that other people have adopted green lifestyles and by highlighting benefits of a sustainable lifestyle. 
  1. Timely: On a daily basis, humans make 90% of decisions using System 1, automatic thinking. Considering that nudges are the most effective way to change people’s lives and that, due to present bias, people value the present more than what lies ahead, incorporating positive messages can influence people’s decisions. For instance, one could help people understand the advantages of adopting immediate environmentally friendly habits, and help them plan ahead to avoid or minimise the consequences of climate change. 

The Power of Default Options

Making sustainable behavior the default option means nudging people to stick to the default choice or status quo, in other words availability heuristic, a type of cognitive bias which reinforces people’s decisions based on the information they already have. 

Between 2019 and 2020, a study was conducted in ten Chinese cities to understand how green nudges – pop-up reminders would not appear upon online food ordering – can affect individuals’ cutlery decisions when placing food-delivery orders. Seven were controlled cities without nudges (Qingdao, Xi’an, Guangzhou, Nanjing, Hangzhou, Wuhan, and Chengdu), and three were controlled cities with “no cutlery” default nudges (Beijing, Shanghai and Tianjin). Behavioral differences between the customers in cities with nudges and those in the control cities before and after the introduction of green nudges were compared. The study used customer-level data in collaboration with food delivery platform, Eleme. 

Upon ordering, customers in controlled cities with green nudges could choose the number of single-use cutlery (SUC) sets they wanted, with the default options being “no cutlery.”

The before and after the green nudge interventions based on a study of Alibaba-owned food delivery app

Customers who chose the option of “no cutlery” received green points, which could be redeemed for planting a real tree in a desert area. For instance, 16 green points could be earned upon an order without SUC. With 16,000 points, customers could request a real tree to be planted in a desert region of China. 

The concept of changing the default option to “no cutlery” and rewarding consumers with green points on Alibaba’s food-delivery were part of the behavioral economics and social psychology’s concept of nudging. The study found that green nudges increased no-cutlery orders by 648%, particularly among women, older individuals, frequent food-delivery-service users, and wealthy individuals. Overall, the company’s performance remained unaffected, suggesting that this nudge was cost-effective in reducing SUC waste. 

The experiment demonstrates that the proper use of nudges can lead to positive changes, influencing consumption behavior towards more ethical and sustainable choices and increasing environmental awareness.

The research is particularly reflective of today’s consumerism-based society, where the growth of takeaways and food delivery services has given rise to a series of environmental issues, including plastic pollution and food waste. The US online meal delivery market size reached US$29.1 billion in 2023 and it is expected to reach US$68.6 billion by 2032. If these numbers are not alarming enough, then what is? 

Framing

Messages and choices can be framed to influence people’s choice architecture. Framing can also lead to intrinsic motivation to act if it is placed properly. According to a 2012 article, gain-framed messages are more effective than loss-framed messages in terms of promoting prevention behaviors. 

Likewise, another 2010 research concluded that climate change behaviors may be effective if the topic revolves around the gains of climate change actions instead of the losses due to inaction. As a result, the use of powerful and encouraging messages can be used to draw people’s attention and motivate them to challenge themselves to act wisely. 

For example, using posters or sharing message prompts stating that a ton of recycled paper can save 17 trees might be more beneficial than telling people that using papers everyday is harmful to the environment.

Gamification and Incentives

Gamification and incentives can be powerful behavioral nudges to encourage sustainable choices. By turning sustainable behaviors into engaging games or providing rewards for environmentally friendly actions, individuals are more likely to adopt and sustain these behaviors. One such example is Germany’s Deposit Return Scheme, said to be one of the world’s most successful systems for refillable beverage containers, achieving a 98% return rate. 

Through this scheme, consumers receive varying incentives for returning reusable and single-use containers. For example, all single-use plastic bottles, aluminium cans, and glass bottles are worth €0.25 (US$0.27). The price for reusable bottles is reduced to €0.08 for glass bottles and €0.15 for plastic bottles.

Making Sustainability Salient and Tangible

As aforementioned, present bias often makes people prioritise immediate gains over long-term benefits, and sustainability can sometimes feel abstract or distant. Behavioral nudges can overcome this by making sustainability more salient and tangible. Providing visual cues, such as real-time energy usage displays, can make individuals aware of their impact and encourage energy-saving behaviors. Additionally, using vivid imagery or personal stories that highlight the tangible benefits of sustainable choices can enhance their appeal and motivate action.

For example, in Hong Kong supermarkets, consumers are charged extra HK$1(US$0.13) for a plastic bag, a move that has led to a significant decrease in the use of shopping plastic bags. Doubling the levy scheme from HK$0.5 to HK$1 has so far been effective in influencing people’s choices and more consumers have become aware of their impacts on the environment ever since the campaign kicked off in 2009.

Final Thoughts

Green nudges can be a game changer in today’s generation to promote sustainable choices and to address the environmental challenges we face. Not only are people’s attention spans getting shorter, but they are easily distracted. 

Behavioral nudges offer a promising approach to encourage individuals to make environmentally friendly decisions. It allows policy analysts and behavioral economists to study how humans make decisions and propose nudges to influence their choice architecture. 

By understanding human behaviour and leveraging techniques such as defaults, framing, and gamification, and many more, we can nudge people towards sustainable choices without compromising their freedom.

About 3,353 tonnes of food are sent to landfill every day in Hong Kong, the equivalent of the weight of 233 double-decker buses. To fight the growing challenges of food waste and plastic pollution, in 2021, the city’s Legislative Council passed a new waste disposal ordinance which is set to come into effect on April 1, 2024. This article aims to explore the key features of the scheme as well as its potential advantages and drawbacks.

Background

Hong Kong generates a substantial amount of solid waste each day, which is causing long-term environmental problems on a local and global scale. Indeed, solid waste directly contributes to greenhouse gas emissions through the release of methane during anaerobic decomposition process of waste, a potent greenhouse gas with 84-86 times higher in global warming potential than carbon dioxide across a 20-year period.

According to the Hong Kong Environmental Protection Department (EPD), in 2021, 5.67 million tonnes of solid wastes were disposed of at landfills, with municipal solid waste (MSW) accounting for over 70% of the total. 30% of it is food waste, followed by plastics (21%) and waste paper (20%). Hongkongers dispose of 1.53 kilogrammes of MSW per day, two times higher than the global average, with a recycling rate of only 31%. 

Why is this alarming? According to data by the World Bank, the East Asia and Pacific region generated the most waste in 2016, and it is forecast to be the leading waste producer from 2030 to 2050. In 2016, solid waste treatment and disposal generated 1.6 billion tonnes of carbon dioxide-equivalent greenhouse gas emissions, accounting for 5% of worldwide emissions. 

Hong Kong has already closed 13 of its landfills, and the remaining three – West New Territories (WENT), South East New Territories (SENT) and North East New Territories (NENT) – are expected to be depleted soon given the current disposal pace. 

Recognising the urgent need to tackle this issue, in 2021, the government implemented the Municipal Solid Waste (MSW) Charging Scheme, a crucial step towards waste reduction and effective resource management.

Municipal Waste Charging

The Municipal Solid Waste Charging Scheme will be implemented in accordance with the “polluter-pays” principle for waste disposals from all sectors, including residential and non-residential establishments (commercial and industrial sectors). 

The “Waste Blueprint for Hong Kong 2035” released in February 2021 includes a medium-term target to decrease the amount of waste disposed of per person by 40-45%, and to increase the recovery rate to approximately 55% through the implementation of regulatory policies, promotion of awareness campaigns, public education, and other measures. In the long-term, the government plans to achieve “Zero Landfill” by 2035 through the development of sufficient waste-to-energy facilities and by eventually eliminating the need for landfill disposal altogether. 

Charging Modes

Dual charging modes have been proposed, namely “charging by authorised bags/labels” and “charging by weight via gate-fee.” 

The designated bags charges apply to MSW collected by the Hong Kong Food and Environmental Hygiene Department (FEHD) via refuse collection vehicles (RCVs) and refuse collection points (RCPs), as well as by private waste collectors (PWCs) using RCVs equipped with rear compactors. Pre-paid designated bags will be available in nine sizes ranging from three to 100 litres. The price will be HK$0.11/litre for the first three years, and $11 per-label for oversized waste. Starting February 2024, these specified bags and labels will be accessible at authorised retail establishments such as supermarkets, convenience stores, pharmacies, and online platforms.

The “gate-fee”, on the other hand, applies to MSW collected and disposed of by private waste collectors (PWCs) using RCVs without rear compactors based on the weight of MSW disposed of at waste disposal facilities, excluding the mandatory use of designated bags or labels.

What Are the Benefits of a Municipal Waste Charging Scheme?

1. Encourage waste reduction and promote recycling

Due to limited land spaces for waste disposals, the primary objective of the scheme is to incentivise waste reduction at the source. By imposing charges on waste disposal, individuals and businesses are motivated to reduce waste generation, adopt recycling practices, and make informed choices about consumption patterns. 

Under the new proposed policy instrument, each household in Hong Kong will pay up to HK$55 (approximately US$7) per month, on average, for waste disposal. Hence, it is expected residents and businesses will consider alternatives to save on waste charges. One way to do this is by following the ‘3Rs’ principle: reuse, reduce, and recycle.

2. Shift responsibility and raise awareness

The scheme emphasises the principle of “polluter pays”. This will shift responsibility for waste management from the government to waste producers, making individuals and businesses more accountable for the waste they generate. 

To facilitate the smooth implementation of the scheme, the government has launched extensive public education campaigns such as “Dump Less, Save More”. The project aims to provide firsthand experience in a quantity-based charging implementation through community involvement projects and collaboration with government departments and stakeholder groups such as the Environmental Campaign Committee, village representatives, green groups, and schools in launching activities. These initiatives aim to raise awareness about waste reduction, recycling, and the benefits of sustainable waste management practices.

3. Cut greenhouse gas emissions

A 2022 study on China’s household waste management system revealed that the measure is contributing to reducing climate change impacts, including emissions. This is because less municipal waste translates into less energy required to transport and process that waste. 

Additionally, waste reduction can also reduce the amount of methane produced in landfills, which account for 8% of global emissions

4. Waste Control

By introducing financial incentives, the scheme encourages individuals and businesses to actively reduce waste generation. This can lead to a significant decrease in the overall volume of waste disposed of in landfills. 

A 2008 published study conducted on 954 Japanese municipalities with pay-as-you-throw (PAYT) systems in place experienced an overall reduction in waste generation. In particular, case studies of four municipalities showed that the implementation of PAYT programs reduced the amount of residual waste generated by 20% to 30%. Moreover, when combined with other measures, such as the recycling of containers and packaging, PAYT programmes were found to bring about significant reduction in waste.

5. Improve waste reduction and recycling efforts

According to the government, with the idea of “dedicated-fund-for-dedicated-use“, the revenue generated from the MSW charging scheme will be used to enhance waste reduction and recycling work, a move that is expected to improve the efficiency and sustainability of waste management in Hong Kong.

Potential Drawbacks

An introduction of a unit pricing system on waste disposal can significantly raise the cases of illegal dumping. 

A research conducted between 2001-2003 and looking at 16 provinces in South Korea found that an additional increase in the pay-by-the-bag unit pricing system of legal disposal had little effect in reducing overall waste generation. For instance, a 1% increase in the legal bag price led to a 3% increase in the number of reports of illegal dumping. On the other hand, a 1% increase in the compensation for recycled goods led to a 6% decrease in the number of reports of illegal dumping. 

Moreover, a 2003 study of 533 PAYT municipalities conducted by the Japan Waste Management Association found that 68% of municipalities had faced issues related to illegal dumping, with 42% experiencing inappropriate discharge and 26% experiencing increased illegal dumping. 

Illegal waste disposal harms the environment and society by degrading public lands, lowering property value, affecting visual appeal, attracting more illegal waste disposal, and increasing government clean-up costs. Hence, it is imperative to formulate an effective policy that will prevent the outbreak of illegal waste disposal in Hong Kong and allocate resources towards the promotion of recycling initiatives. 

A 2019 paper investigating the reasons behind illegal waste disposal suggested that the issue could be prevented by raising public awareness and eco-responsibility through education programmes as well as by emphasising the environmental and health hazards via visual stimuli and messages in text nudges at designated disposal sites. 

Furthermore, the government enforcement efforts should be differentiated across different areas. For instance, the Environmental Protection Department intertwined with the Food and Environmental Hygiene Department (FEHD) can incorporate the utilisation of monitoring surveillance systems in blackspots such as staircase, refuse rooms, and roadsides to refrain people from illegal dumping.

Will the Scheme Work?

In this regard, MSW Charging, coupled with the banning of single-use plastics tableware in 2024, can be seen as transformative legislative measures taken by the Hong Kong government to address the long-standing environmental issues. The Municipal Waste Charging Scheme in Hong Kong represents a significant step in the city’s journey towards sustainable waste management. 

By encouraging waste reduction, promoting recycling, and shifting responsibility to waste producers, the scheme can address the pressing waste management challenges faced by the city. With effective implementation and continued public support, the scheme has the potential to transform Hong Kong into a greener, cleaner, and more environmentally conscious metropolis. Though Hong Kong is in its initial phase of the MSW Charging scheme, prior examples from other countries can be taken into account to ensure the successful implementation.

In the heart of Hong Kong’s vibrant cityscape, where towering skyscrapers and bustling shopping streets define the daily rhythm of life, materialism and consumerism trends have become a norm. Our consumption choices have come at a huge cost to the environment and human society, contributing to climate change and other related environmental issues such as landfill waste and unprecedented levels of greenhouse gas emission. According to Greenpeace, Hongkongers discarded 110,000 tonnes of textiles to landfills in 2014, the equivalent of approximately 1,400 t-shirts per minute. Did you know that it takes over 20,000 litres of water to produce one kilogramme of cotton, which is equivalent to one t-shirt and one pair of jeans? In this article, we look at minimalism as a potential solution to alleviate the environmental burden arising from consumerism and as a way to encourage consumers to make more sustainable choices.

The Minimalist Lifestyle

The central philosophy of minimalism underlines the concept of “less is more.” In other words, being a “minimalist” means possessing fewer items, living a simpler life while having minimal impacts on the environment. Though the original concept of minimalism dates back to the ancient Greek idea of simple living and avoiding excessive material wealth that causes unnecessary waste, the modern minimalist lifestyle that we come to know about has its roots in the 20th century, emerging from artists like Donald Judd and Dan Flavin. 

More importantly, books like The Life-Changing Magic of Tidying Up by Marie Kondo, Goodbye, Things: The New Japanese Minimalism by Sasaki, and Danshari: Shin Katazukejutsu by Yamashita popularised this philosophy. The three kanji characters “断捨離” can be read as  “Dan-sha-ri” and translate to refusal, disposal, and separation, respectively. This concept encourages individuals to shed old habits, reduce the desire for new items, eliminate attachments, and prioritise personal needs. According to an article published in The Japan Times (2011), this term gained popularity in Japan in 2010 and has since spread globally. An article published in the Journal of Human Behavior in the Social Environment (2023) argues the aforementioned social movements have laid the groundwork for minimalism, which has evolved into the minimalist lifestyle we know today.

Nowadays, minimalism refers to a lifestyle that prioritises the quality of life while emphasising environmental sustainability. For example, a minimalist practices careful consideration, avoids overconsumption and waste of resources from purchasing to disposal decisions. This way of life values sustainable living, often with the goal of conserving the Earth and eliminating unnecessary waste in society. This simplified way of living can help an individual achieve a sense of tranquillity and take up environmentally friendly initiatives.

Hong Kong Consumerism and Its Environmental Impact

Hong Kong is battling with several pressing environmental issues, from outdoor air pollution and plastic pollution to landfill waste and biodiversity loss. In recent years, the government has implemented a number of environmental regulatory frameworks to tackle these aggravating problems, including the Air Pollution Control Ordinance (APCO), Water Pollution Control Ordinance (WPCO), Waste Disposal Ordinance (WDO), and Producer Responsibility Schemes (PRS), and in 2021 has pledged to achieve carbon neutrality by 2050. 

On a global level, in 2015, United Nations member states launched the Sustainable Development Goals (SDGs), 17 goals that focus on improvement and longevity, from ending poverty to tackling climate change. However, according to a 2019 report by the UN Economic and Social Commission (ESCAP), Asia and the Pacific will not achieve any of these goals by 2030. 

“If there are environmental policies, why is it not enough to mitigate the climate crisis?” one might ponder. The answers lie in these data.

Air Pollution

A paper published in the National Library of Medicine (2020) ranked “air pollution” as the fourth major risk factor for global disease and mortality, with a recent study suggesting that South Asia, home to four of the five most polluted countries in the world, accounts for more than half of the total life years lost globally due to air pollution. In this part of the world, experts estimate that polluted air cuts life expectancy by about five years. 

Meanwhile, another paper estimated that 12% of global deaths in 2019 was linked to outdoor and household air pollution. This goes to show that air pollution is not only a public health hazard but also a global threat that can have severe repercussions on human health and the environment. The public and the government must do more to address environmental issues.

In Hong Kong, air pollution is among the most pressing environmental issues. The Air Quality Health Index (AQHI) shows that areas such as Causeway Bay, Central, and Mong Kok, all exceeded the World Health Organization (WHO) air quality guidelines

According to a 2020 report by the Hong Kong Environmental Protection Department (EPD), the major types of chemicals released into the air were carbon monoxide, followed by nitrogen oxides and volatile organic compounds, and the major pollution sources were road transport, navigation and public electricity. In 2022, the total number of private cars registered in Hong Kong was 649,540, a significant increase of almost 32,000 from 2018, though it decreased from 2021 by nearly 7,500. 

Waste

Hong Kong has made headlines for its frenetic consumerism culture; the territory ranks high in 10 of 12 indicators signifying excessive materialistic possessions and an unhealthy dependence on shopping. As much glitz and glamour as fast fashion portrays, its environmental impact has been significant. 

According to the Hong Kong Trade Development Council (HKTDC) Principal Economist Louis Chan (2022), the global fashion industry releases as much as 3.3 billion tonnes of greenhouse gas emissions a year, while the global value of discarded clothing has reached US$460 billion a year, of which only 13% can be recycled. This demonstrates that consumerism can be associated with poor waste disposal

A 2021 report by the Hong Kong Environmental Protection Department indicates that the total disposed quantity of solid waste in that year was 5.67 million tonnes, an average of 15,533 tonnes every day and an increase of 5.4% compared to 2020. Municipal waste consisting of domestic, commercial & industrial, construction and special wastes are disposed of at landfills, which hold properties toxic for humans and the environment.

The Minimalism Edge: Streamline Your Life for Maximum Joy

Hong Kong resident and minimalist Nicole Ng told Earth.Org that she is mindful when shopping and chooses quality products even though sometimes it means paying a little extra. 

“Quality shopping is unquestionably the key to more sustainable, durable, and multifunctional products,” she said. 

As a plant enthusiast, she often purchases second-hand plants on platforms like Carousell, Instagram Shop, and Facebook Marketplace, and puts her own plants for sale as she believes it is a more environmentally friendly practice. 

“I came across a video on minimalism by Marie Kondo on Youtube as a university student,” she said when asked what influenced her to get into this lifestyle. “I realised it is much easier to adopt a minimalist lifestyle than I had expected after doing some research.”

Now, Nicole embraces minimalism by decluttering her wardrobe and kitchenware on a seasonal basis. She said starting this lifestyle has improved her mental and physical health, besides increasing her awareness of the environmental impacts of consumerism, adding that having a clear mindset and setting goals help motivate her to stay on track and develop long-lasting habits.

Minimalism: A Sustainable and Healthy Choice

Minimalism encourages individuals to declutter their life by either donating or recycling responsibly. Being mindful about our own consumption habits can make us more conscious about material possessions and force us to buy less as well as to choose quality over quantity. It also encourages consumers to make environmentally conscious decisions, forcing them to ask themselves questions such as “Do I really need this?” and “What are the long-term benefits and environmental impacts of my consumption choices?” 

Pursuing a minimalist lifestyle helps lowering one’s carbon footprint, with benefits not just on an individual level but also on the surrounding environment.

Individuals who adopt a minimalist lifestyle are more likely to live a healthier lifestyle, improving their mental and physical health. A 2021 study carried out in the US found that minimalists feel fulfilled and respected while less likely to experience a feeling of depression. 

Another 2023 research conducted among 525 participants in China revealed that minimalism improves personal well-being in developing countries. Excessive possession, according to the study, does not lead to greater happiness but rather to increased stress and anxiety. 

While officially classified as a developing country, in recent decades, China has experienced the benefits of rapid economic growth. As ordinary Chinese people’s living circumstances improve, so does their need for high-quality goods. For instance, during the eight-day “Golden Week”, also known as the National Day or the October Holiday – a week-long holiday that takes place annually – the domestic tourism revenue reached 753.4 billion yuan (US$103 billion), up 1.5% from the comparable level in 2019. This is a great illustration of ordinary Chinese people’s ravenous appetite for shopping and consumption and how this is often directly linked to increased standard of living. 

Nonetheless, the study also stated that with economic progress and a declining birth rate, China may soon witness increasing acceptance of minimalism, as observed in several developed countries. 

In addition, reduced purchases save money on items that add no value to one’s life. In other words, consumers who adopt minimalism limit their spending and build up savings, which helps them achieve long-term goals that translate into more fulfilment and happiness. Hence, one aspect of minimalism is attaining financial well-being due to spending less, which leads to avoiding unnecessary debt and enhanced savings. Moreover, a 2023 finding in Pakistan shows that there is a positive relation between minimalism and financial well-being.

Criticism

Some critics claim that the minimalist lifestyle promotes new types of consumption, a desire to purchase multi-functional, energy-saving or wanting to renovate a home that resembles the typical minimal space

A 2016 article published in the New York Times Magazine explains that “minimalism is now synonymous with self-optimization, a trend that has also given rise to fitness devices and Soylent. This optimisation, which is frequently driven by technology, is costly and exclusively branded by and for the elite.” 

The author criticises the fact that a minimalist lifestyle will pressurise people to be obsessed over what to declutter and how many items one should own, raising concerns over the consequences of minimalism, such as what would happen if minimalists discarded too many goods at once. The article depicts the movement as arrogant and a trend for privileged people, arguing that being a minimalist requires social capital, a safety net, and access to the internet, something that not everyone possesses.

Final Thoughts

While these are valid concerns, it is undeniable that the minimalist lifestyle offers a transformative approach to living. By reevaluating consumerism, decluttering spaces, practising mindful consumption, and cultivating balance and well-being, individuals can find solace and purpose in the midst of the urban frenzy. 

While the above-mentioned environmental issues may affect Hongkongers’ quality of life as well as many aquatic and terrestrial ecosystems, an adoption of this lifestyle offers a beacon of hope in mitigating climate change. 

Renowned chimpanzee researcher and activist Jane Goodall once said: “Each one of us matters, has a role to play, and makes a difference.” 

Therefore, embracing minimalism in Hong Kong is not only a personal choice; it is a step towards creating a more sustainable, mindful, and fulfilling way of life in this vibrant city. So, let us embark on this journey of simplicity, embrace what truly matters, and rediscover the beauty of living with less in the midst of Hong Kong’s abundant offerings.

If you like to get started but don’t know where to start, you may follow these simple 5 steps.

  1. Decluttering your environment and mind
  2. Be mindful when purchasing 
  3. Take advantage of digital platforms
  4. Try recycling and reusing as much as possible
  5. Form a habit to get organised
