World Habitat Day
October 2, 2019 @ 8:00 am - 5:00 pm
World Habitat Day, which is celebrated on the first Monday of October, brings attention to UN-Habitat’s mandate to promote sustainable urban development policies that ensure adequate shelter for all.
This year’s theme is Municipal Solid Waste Management. In 2010 it was estimated that every day 0.8 kilograms of waste is produced by every person in the world. And the amount of total waste generated is expected to triple to 5.9 billion tons a year by 2025, due to increased consumption and ineffective management strategies.
Cities often spend a large proportion of their budget on Municipal Solid Waste Management which should be at the top of the agenda for cities, their inhabitants and governments at national and local levels. Cities should aim to become ‘Waste-Wise Cities’.
The Sustainable Development Goals (SDGs), the Paris Agreement and the New Urban Agenda, address the key issue of solid waste management. The target of SDG11.6 is to reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management with indicator 11.6.1 being the proportion of urban solid waste regularly collected and with adequate final discharge out of total urban solid waste generated by cities. SDG 12 on “Sustainable Production and Consumption” targets among other things, environmentally sound management of all waste through prevention, reduction, recycling, reuse and the reduction of food waste.
The New Urban Agenda makes a commitment to “the environmentally sound management and minimization of all waste”. Under the Paris Agreement, Nationally Determined Commitments (NDCs) of many countries, include action on waste management to reduce greenhouse gas emissions. Translating the national government commitments to practical and sustainable actions at the local level, needs the support of a network of actors with local authorities taking the lead to maximise partnership opportunities.
Developing countries often have inadequate waste management systems due to lack of financing, poor awareness, poor governance systems and sometimes inappropriate applications of technological solutions. Poor collection and disposal of municipal solid waste causes local flooding and water pollution and accumulated waste provides a breeding ground for rodents and insects which spread disease. Marine litter and erosion of coastal dumpsites contribute to marine pollution.
Uncontrolled waste-burning adds to air pollution while poorly maintained waste transportation vehicles and landfills contribute to greenhouse gas emissions.
High-income countries generate more waste per-capita than low- income countries. In rapidly-urbanizing areas, suitable sites for sanitary landfills is becoming scarce due to the increasing price of land and objections from the community.
Wider use of electronic goods and their built-in obsolescence leads to “waste trafficking” with e-waste produced in developed countries ending up in dump-sites in developing countries with lower environmental standards and labour costs.
Poorly managed landfills pose many health hazards particularly for informal waste pickers. These include air pollution, injuries and landfill collapses. In 2017 alone more than 130 people, most of them women, died in landfill collapses in Africa. Children are also frequently
employed in this dangerous occupation and are deprived of educational opportunities.
The trans-boundary movement of municipal solid is an inexpensive way to circumvent local environmental laws related to disposal but must be discouraged. Although appropriate recycling industries may not be available locally, every effort should be made to establish such facilities.
Municipalities often spend up to 70% of their budget on waste management, including on street sweeping etc. Aside from high investment costs for equipment, a sizeable number of staff are also required. The quality of a city’s waste management system is often used
as a guide to the overall effectiveness of municipal management. However, government investment in solid waste management is low compared to other sectors such as water and sanitation. The main difficulty lies in providing an equitable charging system. In addition,
solid waste management is a low priority for development finance institutions. In 2012, only 0.32% of global development finance went to solid waste management while water and sanitation received 31%. Africa, compared to the Latin America, Caribbean and Asia regions
received the least investment.
Trends in consumption and production, manufacturing product cycles, public attitudes, municipal governance systems, capacity of city managers and innovative financing for solutions are all part of the solution to solid waste management. In addition, transparent and
rules-based engagement of all stake-holders including waste producers, the waste recycling industry and waste workers is key. Integrating the informal waste recycling sector in the organized economy, with adequate health and safety provisions for workers can change the
current informal and dangerous jobs of waste collectors. Developing a market for innovative and attractive products made from waste material can help to integrate the informal waste sector in the economy.
Greenhouse gas emissions from solid waste accounts for about 3% of the global total (IPCC 2010) but the potential contribution of better waste and resource management to climate change mitigation is much higher.
Recognising that municipal waste management needs and approaches varies from city to city, UN-Habitat recommends that solutions are built on respective cities’ assets and strengths either in the formal waste management system or in the informal or micro enterprise sectors. Developing a network to share experiences and good practices will allow cities to learn from each other.
UN-Habitat thus promotes an “Integrated Solid Waste Management Framework” which envisages: good waste collection services; environmental protection through proper treatment, disposal and resource management; cost-effective, affordable, and inclusive
solutions which also recognize the role of informal and micro-enterprise sectors in achieving high rates of recycling.
Cities need to explore how increasing land values can be channeled towards better waste management. For example, cities could examine the real cost of providing waste collection services to high-income, low-density neighborhoods, taking into account the quantity of landfill space required to accommodate such waste and charge residents according to the volume of waste. In some cities, reclamation of land through treatment of landfill sites and the use of disused quarries as landfills have been tried and can be studied for potential replication.
Education and awareness activities have a key role to play and local governments can engage with civil society and advocacy groups to raise public awareness with schools as a possible focus. UN-Habitat’s field experience has shown the efficacy of child to parent teaching of
better hygiene practices and this could be replicated with municipal waste. Incentives to change public behavior such as paying for the return of used plastic bottles can be effective. Manufacturers need to improve packaging to reduce waste or by making packaging waste more easily recyclable.
