On the ground, it is not too difficult to see why this is so. More than 40% of residents rely on public transport, but with 45 residents competing for one bus seat, travel within the city is difficult. Water supply is highly irregular, and rationing is widespread. The availability of water ranges from four hours per day to two hours every other day. Many households rely on private vendors who sell water from tankers at high prices. The sewage network has not been well maintained since the 1960s, and all three existing treatment plants are dysfunctional. Industrial waste, which contains hazardous materials and heavy oils, is dumped directly into the sea untreated. Of the 12,000 tons of municipal solid waste generated each day, 60% never reaches a dumpsite; 80% of medical waste is not disposed of properly.
Last November, 345 “Zika Warriors” took to the streets of Jamaica to fight the spread of the Zika virus in 30 communities. These local residents trained as vector control aides to prevent Zika primarily by improving waste management in their communities, including cleaning up public spaces and destroying mosquito breeding sites. In addition, they distributed bed nets to pregnant households.
As we observe World Health Day today, we look back with great thanks to the significant reduction in Zika in these communities. Anecdotal evidence suggested that the Zika Warriors significantly stemmed the spread of the virus, especially compared to the 2014 Chikungunya outbreak that led Jamaica to declare a state of emergency.
As a first responder to the pandemic, the Jamaica Social Investment Fund (JSIF) designed this program within an existing waste management program of the World Bank’s Integrated Community Development Project, directly benefitting more than 140,000 citizens.
In a rapidly urbanizing world, our incautious thirst for plastics and non-degradable products continues to adversely affect local environments and air quality, and contributes to climate change. The need to rethink how to collect and dispose of solid waste is urgent. Whilst many countries and cities have put forth encouraging efforts to recycle and reduce waste, the levels of consumption and the production of waste continue to increase.
At the same time, the recycling industry has started to grow because of new initiatives, community organizations and private companies. There are a few organizations that repurpose waste into arts and crafts, tools or apply it as a source of energy – such as WasteDar. However, the majority collect or purchase plastic waste from collectors, primarily with a view to export, rather than recycle or reuse locally.
Socially and environmentally, waste management is one of the biggest challenges for an increasingly urbanized world. Waste pickers can earn as little as US$1-2 a day in dangerous conditions with little opportunity for advancement. They make up some of the most disadvantaged communities living in deep poverty.
Through a new market for sorted waste materials, these communities may access higher income generation opportunities in a sustainable manner. This presents an opportunity to explore turning this waste into value more close to home.

Colleagues often make fun of me - a physician who does not manage patients, but healthcare waste. I must confess that I have a strange job. When I visit hospitals, I do not walk through the front gate, but go around, behind the buildings. There I do not provide medical advice, but rather I motivate people to clean up a contaminated place.
More and more people in the health sector are enthusiastic about these unusual roles. Dr. Nguyen Ngoc Dzung, Director of Kien Giang Traditional Medicine Hospital, inspired all staff with her commitment that ensures people “do not see and do not smell healthcare waste” at any location in the hospital.
Every day, the world’s population generates enough waste to fill about 14 large soccer stadiums from top to bottom, more than 3.5 million tonnes. That's a lot of trash, from plastic bottles that aren't going anywhere to food scraps and other perishable items decaying and building up greenhouse gases in landfills and trash dumps.
Management of organic waste is a major dilemma for developing countries. It generates unpleasant odors and helps rats, flies, bugs and mosquitoes multiply and spread diseases. As it decomposes, organic waste generates methane, a gas that contributes significantly to global warming. Last year Daniel Hoornweg, Perinaz Bhada-Tata and Chris Kennedy predicted in an article in the magazine Nature that the global rate of solid waste generation is expected to triple by 2100. This is bad news because if the investment for solid waste management in developing countries remains as low as it is today, the world is at risk of irreversible environmental deterioration.
Urbanization is the most powerful force shaping the planet today. This can be good news as urbanization is the best bet we have to meet our global poverty reduction targets. Cities generate our wealth, our culture, and our innovation. This is also bad news since cities generate the lion’s share of the world’s GHG emissions, and cities are responsible for most of the planet’s current decline in biodiversity. Cities also generate solid waste; lots of it and the amount is growing fast.
‘Peak waste’ – that point in time when all the waste from all the cities finally plateaus around the world, and then slowly starts to decline, is not on track to happen this century. Estimates are that it will peak at three-times today’s current waste generation rate. Peak waste is an excellent proxy for humanity’s cumulative global environmental impact; therefore we are on track to triple today’s overall global environmental impact. Our ‘assault on the planet’ will start to subside on the other side of peak waste. Therefore we must move peak waste forward and reduce its intensity when it finally does arrive.
At the 9th South Asia Economics Students' Meet on Green Growth, participants shared their vision about South Asian cities of the future. These are their innovative ideas.
The creation and expansion of urban centers has been a hallmark of the development process. As per capita incomes in South Asia have increased, urbanization has expanded from 18% in the early 1970’s to 30% in 2010. This will continue to expand as people are drawn to cities for the opportunities to realize their aspirations.
These large urban communities, however, provide significant challenges, such as a high density, pollution and traffic congestion, all of which reduces the quality of life for its residents. By designing cities with the environment in mind, we will be able to reduce energy use and limit waste. Green growth in the cities of the future will minimize the ecological footprint and improve living standards
