Basel Convention, Cities’ Collective Solution to Transboundary Waste

Basel Convention, Cities’ Collective Solution to Transboundary Waste

Following the previous blog post on Guiyu, we learnt of the existence of the Basel Convention, which was introduced as an international agreement to ban transboundary shipment of e-waste. For this post, we delve deeper into the functions of the agreement, and critically evaluate its effectiveness.

The Basal Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal opened for signatures in 1989, and came into force three years later in 1992. It is a multilateral agreement negotiated under the United Nations Environment Program (UNEP), calling for environmentally sound management of exported and imported waste, especially in developing countries. As of November 2020, there are 187 parties to the convention. Parties under the convention are not allowed to export or import any substances that are marked as hazardous under the convention, until the receiving nation agrees to importing the waste. Hence, Basel does not enforce a ban but rather regulates the transshipment of hazardous waste.

Although a good start to tackling waste pollution, the Basel Convention is still unable to fully curb the issue of illegal dumping. Firstly, the Basel Convention is a voluntary international treaty. This means cities get to choose whether they wish to abide by the laws of the treaty. This thus poses the issue of the efficiency of the treaty; what if large waste exporters choose not to sign? Alas, this indeed happened with America, who signed the Convention but has yet to ratify it. This means that America has not made internal legislative changes to reflect the conditions of the treaty, and can technically still export hazardous waste overseas with or without proper consent.

Another flaw of the Basel Convention is the lack of enforcing tools and proper monitoring systems. As the treaty relies heavily on the communication of permits between the importing and exporting country, any lapses in the treaty is dealt with by these two nations. This makes accountability an issue, as wealthier countries have greater means of avoiding penalties. Dispute between countries can be brought up to the International Court of Justice, but oftentimes the cases are dismissed due to lack of environmental cases to base judgement off, as well as again lack of enforcing power.

Albeit the apparent shortcomings of the Basel Convention, it is still a notable attempt by the world to come together and tackle transboundary pollution. This treaty will enhance communication and the exchange of information, and kickstart the journey of accounting for each city’s toxic waste.

Urban Revitalisation of Seoul City

Urban Revitalisation of Seoul City

In the aftermath of the World War II, many Asian countries placed growing their economy as a priority, which resulted in rapid urbanisation and the negligence of quality of life and proper urban planning (Y.-K. Lee et al., 2014). For this blog post, we place focus on the case study of the Cheonggyecheon restoration project, an attempt by Seoul City to veto the horrible air pollution and poor quality of life brought about by poor urban design in the past.

The Cheonggyecheon is an eleven-kilometre stretch of stream that flows through the central part of Seoul, the capital of Korea. The water in the previously ephemeral stream Cheonggyecheon originates from the highlands north of the stream, such as the Bukhan mountain (Jeon & Kang, 2019). Cheonggyecheon then flows and connects to the Han River, which drains out into the Yellow Sea.

Prior to the restoration in 1958, Cheonggyecheon stream was buried under an expressway that was 50m wide and span 6km in length. Later in 1976, an elevated highway was built upon the pre-existing highway to mitigate congestion issues (Kim & Jung, 2019). As majority of the land-use around Cheonggyecheon was roads and traffic, it led to a decline in air quality around the Central Business District (CBD) area of Seoul. A study found that citizens who worked or lived near the area were twice as likely to suffer from respiratory illnesses as compared to other Seoul citizens (Hwang, 2004). This was due to the high nitrous oxide and benzene levels from idling vehicles.

Talks of restoring the Cheonggyecheon began with the election of Seoul’s first conservative mayor Lee Myungbak in 2002. Lee’s political campaign focused on improving environmental and cultural spaces in the city to increase the quality of life and revitalise the dull urban environment that resulted from the rapid urbanisation in Seoul. The Cheonggyecheon Project promises to do just that; the removal of the expressways encouraged citizens to switch over to active mob ility methods like walking and cycling (Kim, 2007), greatly improving the air quality due to the large decrease in vehicles passing through the CBD area. In fact, the city saw major decline in records of air pollutants such as carbon monoxide, nitrogen dioxide and ozone prior to and after the restoration project (Hoe, 2006).

The Cheonggyecheon project has become a global example that advocated the importance of green and sustainable spaces in a city. It also presents ideas and encouragement of utilising active mobility and public transport as effective ways to curb vehicle air pollution in cities.
