The data revolution is upon us and the benefits, including improving the efficiency of corporations, spurring entrepreneurship, improving public services, improving coordination, and building profitable partnerships, are becoming more evident.
For public services, the potential gains are impressive. Globally in the electricity sector, an estimated $340 – 580 billion of economic value can be captured by providing more and better data to consumers to improve energy efficiency, and to operators for streamlining project management and the operation of their facilities. Even larger gains ($720 – 920 billion) could be captured in the transport sector.
Exploring the benefits of open data in the solid waste sector has been slower than for other services, however, if you take a closer look, the benefits may be substantial. Solid waste services have a lot to gain – with low service coverage and a lack of modernization in most parts of the world; solid waste services can be costly, representing 10 – 50% of municipal budgets in many developing countries; and it is directly dependent on many actors. To be effective, citizens, institutions, and private companies need to be informed and involved.
Some examples of what making better quality data available on solid waste services could do include:
The best laid plans… have data. With average waste collection rates of 41% and 68% for low- and lower middle-income countries, respectively, and less than 10% of the corresponding waste disposed in a sanitary manner, many municipalities in the world lack solid waste services. The introduction of modern solid waste systems in these areas represents a monumental organizational change and logistical challenge. It necessitates the introduction of collection services for, among others, each household, and every commercial building and supermarket; the coordination with, informing, and incentivizing all the actors in recycling; the operation of transport services; and the operation of effective disposal or treatment options for the daily, relentless influx of waste. Systematically collecting quality data will help municipalities to undertake strategic planning, integrate service planning into urban planning, and make the necessary decisions that allow them to establish a solid waste system that is properly dimensioned and cost-effective.
The post-2015 Sustainable Development Goals (SDGs) are an ambitious set of targets that aim to support a comprehensive vision of sustainable development that embraces economic, social, and environmental dimensions. Solid waste plays an important role in several of these goals, including providing sanitation for all, making cities and human settlements sustainable, encouraging sustainable consumption, and reducing climate change.
In the planning undertaken by Multilateral Development Banks (MDBs) to help achieve these goals, one glaring fact stood out: the financial resources needed are not only expected to be substantial, in the “trillions” of dollars annually, but they far outweigh the current “billions” of dollars annually in financial flows from development institutions. Considering this information, it was agreed at the Hamburg G20 Summit that a new approach would be needed to unlock, leverage, and catalyze other sources of financing, including private sector resources.
The approach would more systematically prioritize private financing solutions when they are feasible. That is, private solutions that are already working would be considered as a first option; followed by encouraging private investment by reducing policy and regulatory gaps and risks that currently discourage participation; and, finally, as a last option, when private solutions cannot fulfill all the demands of the sector, public resources could be strategically used.
Considering the successes and challenges of private sector involvement in solid waste, it is an opportune moment to begin to ask: what are the key issues that need to be addressed to better leverage the private sector to provide sustainable solid waste management solutions?
Have solid waste laws done enough? Regulations and policies have progressed significantly, with many countries establishing new solid waste laws that replace decades-old sanitation or public nuisance legislation. Have these reforms gone far enough to specifically encourage the private sector? Are there functional mechanisms for cost recovery, and is there sufficient flexibility for the private sector to pursue a variety of contractual and financing arrangements? Are the laws truly motivating investment into modern facilities by providing enforceable requirements and standards for the establishment of landfills, closing dumpsites, and establishing recycling facilities? Are the financing schemes predominantly focused on public financing, or do they cater to what the private sector financing needs? It is worth a second look at how these laws respond to these and other issues, and learning from thosecountries that have taken them on.
Public spaces such as streets, open spaces, parks, and public buildings are a big part of cities that are often overlooked. Inadequate, poorly designed, or privatized public spaces often generate exclusion and marginalization and degrades the livability of the urban environment. That is why the importance of public spaces are now embedded within the Sustainable Development Goals.
In dense built-up cities like Karachi, Pakistan, public spaces are even more important. These are areas of respite and recreation from the stress of city life. They are also social and cultural spaces where livelihoods and businesses are conducted, especially for the urban poor. Public open spaces in Karachi have suffered from rapid urban growth:
The total share of green space detectable in satellite imagery has fallen from 4.6% in 2001 to 3.7% in 2013.
Large tracts of vacant land in prime areas in the city center are closed off to the public and neglected.
Twelve square kilometers of prime waterfront area, often a valuable public asset in other cities, is still mostly undeveloped more than 10 years after the roads were built.
Many sidewalks in the main commercial areas and busy corridors are broken down, converted to unregulated parking areas, or used for dumping trash—to the detriment of pedestrian safety and public health.
In a focus group, women also remarked on the lack of safe playgrounds or other recreational facilities for children.
Recently the World Bank Group approved a loan for the Karachi Neighborhood Improvement Project (KNIP) to finance improvements in public spaces in the city’s selected neighborhoods and to strengthen the city government’s capacity to provide certain administrative services such as business registration and construction permits. The investments in safety, walkability and access to public transit nodes are also timely, given the city’s plans to introduce a system of Bus Rapid Transit within the city and in two of the three neighborhoods.
Beyond the investments in the physical space and urban design, a key design feature of KNIP is its emphasis on active and sustained engagement with the residents of Karachi. The project aims to use a participatory planning process to identify, prioritize, and design highly impactful enhancements to public areas such as sidewalks, open spaces and green spaces, and public buildings. While the exact nature of investments will be determined through community consultations, they may include safety features for pedestrians and other non-motorized transportation, accessibility and mobility improvements close to commercial areas and planned transit stations, new or upgraded neighborhood parks and playgrounds, infrastructure to foster safe and vibrant street activity (kiosks for vendors, tables and seating, temporary street closures for festivals, etc.), measures to address traffic congestion and parking, and improved municipal services in public areas (street lighting, garbage collection, drainage, etc.).
KNIP is intended to be an entry point to showcase the value of participatory planning and inclusive urban design, as the first step in a longer-term strategy for city transformation and rejuvenation. Building confidence and inclusiveness in city management is critical to ensure the success of deeper institutional reforms and larger infrastructure investment programs down the road. KNIP is expected to help lay the foundation for a multi-year partnership between the World Bank Group and the local and provincial governments focused on inclusivity, livability, and prosperity. To this end, KNIP will also support the creation of a Karachi Transformation Steering Committee (KTSC), comprised of elected officials, government representatives, business leaders, community stakeholders and NGOs representing various public interests. KTSC’s mandate is to develop a shared vision for Karachi’s transformation and a roadmap to achieve that vision in an inclusive way.
It will take Karachi as much as $10 billion of capital investment over the next decade to close the infrastructure gaps in the city.
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.
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.
Plastic waste, in particular PET, which is typically found in soda bottles, is becoming abundant in African cities. In Dar es Salaam, one of the most rapidly urbanizing cities in Africa, BORDA found that about 400 tons of plastic waste per day remains uncollected or unrecycled. Although about 98 percent of the solid waste generated per day can be recycled or composted, 90 percent is disposed in dumpsites.
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.
