Garbage landslide

Last updated

A garbage landslide [1] is a man-made event that occurs when poorly managed garbage mounds at landfills collapse with similar energy to natural landslides. These kinds of slides can be catastrophic as they sometimes occur near communities of people, often being triggered by weather or human interaction. [1] This form of landslide has attracted the attention of anthropologists, news media, and politicians as a result of incidents that have severely damaged communities and killed hundreds of people since the 1990s.

Causes

People and weather can cause garbage landslides by impacting the weight distribution of mounds in landfills, which are sometimes poorly regulated and open to those seeking recyclables for profit. Human interaction can destabilize precarious mounds of garbage as people walk atop them or attempt to remove valuable materials. Such dangerous mounds are frequently found on slopes and hillsides, where landfills often exist due to the lack of value for other development. Impoverished communities may be drawn to build homes near such landfills for extant recycling opportunities, [2] and informal neighborhoods have developed in high-risk areas as a result. People collecting garbage are thus commonly both triggers and victims of garbage landslides, but these events can also be caused by landfill workers driving heavy machinery nearby or adding too much trash to the mounds.

Weather is a common agitator and cause of garbage landslides. [3] Mounds may collapse if they become heavier from rain and disturbances like strong storms can both trigger sliding and start fires if lightning ignites combustible gases from the landfill. Weather may also induce soil erosion, making landfills more vulnerable to sliding events. [4]

Government mismanagement

Landfill mismanagement and public corruption have featured as significant factors to devastating garbage landslides. [5] If layers of garbage are not properly buried, they remain loose and can gradually separate from the effects of weather and people. Poor waste management policies of different governments at local and national levels contribute to a lack of regulation enabling irresponsible dumping and hazardous access to landfills. Poverty in a society is a very important risk factor as the lack of more stable income can motivate people to collect recyclables from or live in such hazardous sites. As of 2017, around 15 million people lived and worked within such landfills. [6]

Several garbage landslides have occurred worldwide since the 1990s in which nearby infrastructure was destroyed or mass casualties occurred. Examples from the 90s include a 1993 methane explosion at a landfill in Istanbul's Ümraniye district, which triggered a landslide that killed 30 people, [7] and a 1996 garbage slide in Ohio at the Colerain Township landfill which destroyed an adjacent limestone quarry. [4] The latter landslide resulted in a 35-acre fire after lightning ignited combustible waste fumes. [8]

These accidents have become more common and more deadly in the twenty-first century. On 21 July 2000 a garbage mound at the Payatas Sanitary Landfill collapsed and slid through the barangay of Payatas outside Quezon City, Philippines, which resulted in the deaths of over 300 people. The tragedy resulted in the Philippine Congress banning all open-air garbage dumps throughout the country. [9] Urban settings can also be affected by these events: During the 2015 Shenzhen landslide a 100-meter tall garbage mound collapsed into a slide and destroyed 33 buildings, some of them multistoried concrete structures, [10] in the Hengtaiyu Industrial Park of Shenzhen in addition to rupturing part of the West–East Gas Pipeline. 45 individuals ultimately faced charges for the disaster and 20 public officials who oversaw the creation and management of the Shenzhen landfill later received prison sentences for corruption. [5]

Incidents such as the aforementioned slides attracted local and international outcry, but many smaller events occasionally strike communities with fatal results and attract little media attention. As populations rise, the volumes of waste that need to be managed grow with them [11] and raise the risk of deadly accidents occurring. The development of communities around poorly-managed landfills has left some populations increasingly vulnerable to garbage landslides, which accounted for 15% of landslides not involving soil or rocks from 1993-2004.

A natural disaster is the highly harmful impact on a society or community following a natural hazard event. Some examples of natural hazard events include: flooding, drought, earthquake, tropical cyclone, lightning, tsunami, volcanic activity, wildfire. A natural disaster can cause loss of life or damage property, and typically leaves economic damage in its wake. The severity of the damage depends on the affected population's resilience and on the infrastructure available. Scholars have been saying that the term natural disaster is unsuitable and should be abandoned. Instead, the simpler term disaster could be used, while also specifying the category of hazard. A disaster is a result of a natural or human-made hazard impacting a vulnerable community. It is the combination of the hazard along with exposure of a vulnerable society that results in a disaster.

<span class="mw-page-title-main">Landfill</span> Site for the disposal of waste materials

A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s. In the past, refuse was simply left in piles or thrown into pits; in archeology this is known as a midden.

<span class="mw-page-title-main">Illegal dumping</span> Act of dumping waste illegally

Illegal dumping, also called fly dumping or fly tipping (UK), is the dumping of waste illegally instead of using an authorized method such as curbside collection or using an authorized rubbish dump. It is the illegal deposit of any waste onto land, including waste dumped or tipped on a site with no license to accept waste. The United States Environmental Protection Agency developed a “profile” of the typical illegal dumper. Characteristics of offenders include local residents, construction and landscaping contractors, waste removers, scrap yard operators, and automobile and tire repair shops.

Municipal solid waste (MSW), commonly known as trash or garbage in the United States and rubbish in Britain, is a waste type consisting of everyday items that are discarded by the public. "Garbage" can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately. In the European Union, the semantic definition is 'mixed municipal waste,' given waste code 20 03 01 in the European Waste Catalog. Although the waste may originate from a number of sources that has nothing to do with a municipality, the traditional role of municipalities in collecting and managing these kinds of waste have produced the particular etymology 'municipal.'

<span class="mw-page-title-main">Ariel Sharon Park</span> Israeli park built on a waste dump placed on a Palestinian village

Ariel Sharon Park is an environmental park along the lines of Ayalon river, in the area between Ben Gurion Airport and Highway 20. The area is 8.5 square kilometers big, and was intended to be the "green lung" of the southern part of Gush Dan metropolin. The park was established on the former Hiriya waste dump located southeast of Tel Aviv, Israel, the Shalem farm, Mikveh Israel village and the Menachem Begin Park. After accumulating 25 million tons of waste, the Hiriya facility was shut down in August 1998. Hiriya is visible on approach into Ben Gurion International Airport as a flat-topped hill. Three recycling facilities have been established at the foot of the mountain: a waste separation center, a green waste facility that produces mulch and a building materials recycling plant. The waste dump and its surrounding area have been renovated into a large park that is still under construction.

Waste management in Japan today emphasizes not just the efficient and sanitary collection of waste, but also reduction in waste produced and recycling of waste when possible. This has been influenced by its history, particularly periods of significant economic expansion, as well as its geography as a mountainous country with limited space for landfills. Important forms of waste disposal include incineration, recycling and, to a smaller extent, landfills and land reclamation. Although Japan has made progress since the 1990s in reducing waste produced and encouraging recycling, there is still further progress to be made in reducing reliance on incinerators and the garbage sent to landfills. Challenges also exist in the processing of electronic waste and debris left after natural disasters.

On 11 March 2017, a garbage landslide at the Koshe Garbage Dump in Addis Ababa, Ethiopia killed 115 people. Koshe, derived from the Amharic word for "dirty," had hundreds of people living in unincorporated communities beneath the 50 year-old garbage dump's unstable mounds. Both shanty houses and concrete structures were built in Koshe by residents attracted to the area's cheap cost-of-living and availability of recyclables to collect for income. Destabilized by constant human interaction, a segment of one of the garbage mounds collapsed during the evening onto one of Koshe's communities.
