The world’s wastewater – 80 percent of which is released into the environment without adequate treatment – is a valuable resource from which clean water, energy, nutrients, and other resources can be recovered, according to a World Bank report released today to mark World Water Day.
The report, Wastewater: From Waste to Resource, calls for smarter wastewater management, including reuse and resource recovery, and looks at wastewater projects around the world which have paid dividends for people, the environment, and economies in the short and long-term.
Efficiently investing in wastewater and other sanitation infrastructure is crucial to achieve public health benefits, improve the environment, and enhance quality of life. Safely managed water, sanitation and hygiene (WASH) services are an essential part of preventing disease and protecting human health during infectious disease outbreaks, including the current COVID-19 pandemic.
“At a time when 36 percent of the world’s population lives in water-scarce regions, wastewater treatment for reuse is part of the solution to water scarcity and pollution problems,” said Jennifer Sara, Global Director, World Bank Water Global Practice. “Once treated, it can be used to replace freshwater for irrigation, industrial processes, or recreational purposes. It can also be used to maintain the environmental flow and by-products from its treatment can generate energy and nutrients.”
Wastewater treatment offers a double value proposition, the report says. In addition to environmental and health benefits, wastewater treatment can bring economic benefits through reuse in different sectors. Its by-products, such as nutrients and biogas, can be used for agriculture and energy generation. And additional revenues generated from this process can help cover water utilities’ operational and maintenance costs.
“In this sense, wastewater should not be considered a ‘waste’ anymore, but a resource. This is at the core of a circular economy, an economic system aimed at minimizing waste and making the most of resources. As cities continue to grow, future urban development requires approaches that minimize resource consumption and focus on resource recovery, following principles of the so-called circular economy,” said Diego Juan Rodriguez, the report’s author and a Senior Water Resources Management Specialist at the World Bank. “One of the key advantages of adopting circular economy principles in wastewater management is that resource recovery and reuse could transform sanitation from a costly service to one that is self-sustaining and adds value to the economy. This will help countries bridge the funding gap in sanitation to achieve the Sustainable Development Goals.”
The report casts a light on wastewater management experiences in the Latin America and Caribbean (LAC) region, which are already reaping benefits. For example:
By using treated wastewater instead of groundwater, the San Luis Potosi power plant in Mexico cut costs by 33 percent, leading to US$18 million in savings over six years for the power utility. For the water utility, the additional revenue from selling treated wastewater helped cover operations and maintenance costs.
A wastewater treatment plant in Cusco, Peru, saves US$230,000 a year in transporting biosolids (nutrient-rich organic materials resulting from the treatment of domestic sewage in a wastewater treatment facility) and landfill fees due to an agreement with the local compost producer. The compost produced with the plant’s biosolids is then used as part of the water management project to preserve the Piuray Lake.
The Brazil-based CAESB water and wastewater utility’s use of biosolids for corn production led to higher-than-average grain yields and was 21 percent more efficient than mineral fertilizers.
The operator of the La Farfana wastewater treatment plant in Santiago, Chile, after investing US$2.7 million to retrofit the plant, was able to sell biogas, accounting for an annual net profit of US$1 million for the business.
The report recommends incorporating wastewater interventions as part of river basin planning, and pairing them with policies, institutions and regulations that foster this paradigm shift. Wastewater treatment plants need to be gradually repurposed as water resource recovery facilities, while also exploring and supporting innovative financing and sustainable business models that leverage the potential revenue streams of resource recovery from wastewater.
Only 30 to 40 percent of the LAC region’s collected wastewater is treated, resulting in negative impacts on both human health and the environment.
The report shows what’s possible when governments at all levels apply circular economy principles to their wastewater challenges. For example, in the city of La Paz, Bolivia, the national and municipal governments, as well as the water utility, with support from the World Bank and other development partners, are working together to incorporate circular economy principles in the design of the La Paz wastewater treatment plant. The goal is to address water pollution and public health issues caused by low levels of wastewater treatment and unregulated use in agriculture.
“We are happy to see that the necessary transformation is well under way – wastewater policies in many countries already include reuse and resource recovery, and we hope more countries will follow suit. Countries need to scale up action,” said Rodriguez.
The report was funded in part by the Global Water Security & Sanitation Partnership (GWSP) and the Public-Private Infrastructure Advisory Facility (PPIAF).
Skills Development Vital to Enabling Transition to Industry 4.0 in Southeast Asia
Countries in Southeast Asia should consider developing industry transformation maps in key sectors to enable the transition to the fourth industrial revolution (4IR) with adequate investment in skills development for new and repositioned jobs, according to a new study by the Asian Development Bank (ADB).
The finding is one of six key recommendations emerging from ADB’s study Reaping Benefits of Industry 4.0 Through Skills Development in High-Growth Industries in Southeast Asia, covering Cambodia, Indonesia, the Philippines, and Viet Nam.
“The future of jobs is at the heart of development in Asia and the Pacific,” said Director General of ADB’s Sustainable Development and Climate Change Department Woochong Um. “While jobs have been lost to automation in recent years, new jobs will emerge as new and disruptive technologies are adopted. Now is the time to invest in skills development that will help displaced workers acquire the abilities necessary to move into new jobs and help job-seekers access quality jobs for greater prosperity.”
The study assesses two industries in each country deemed important for growth, employment, and 4IR. Based on employer surveys, the study reports large potential returns to businesses arising from productivity increases from 4IR technologies.
By 2030, there is likely to be a positive net impact in all industries analyzed with more jobs created than displaced. Although a third of agro-processing jobs in Viet Nam may be displaced, for example, substantial net job creation of 34% is possible. There could also be net increases of 39% for garments in Cambodia, 14% for food and beverage manufacturing in Indonesia, and 11% for IT-business process outsourcing (BPO) in the Philippines.
“The findings of the study point towards a clear path for the future in Southeast Asia,” said ADB Director General for Southeast Asia Ramesh Subramaniam. “While the region may face challenges in moving the displaced workers into new jobs due to inadequate skills, we are confident that countries will design appropriate policies and invest in workforce skills particularly to accelerate the post-pandemic recovery. We must do everything possible to ensure that no one is left behind.”
Employers in all industries surveyed stressed the importance of skills in the context of disruptive technologies. Together, they could need an additional 169 million people trained by 2030 to prepare for the transition to 4IR.
The study recommends strengthening on-the-job training and skills development for the jobs of tomorrow. It calls for developing industry-led technical and vocational education and training programs with dedicated credentials for 4IR, and flexible and modular skills certification programs that recognize skills attainment outside of traditional education channels.
The study revealed mismatches between training institutions and employers on the perceived readiness of graduates for the workplace. While 96% of training institutions surveyed in Indonesia believed their graduates were well-prepared for work, only 33% of food and beverage manufacturing employers agreed. In Cambodia, almost 90% of surveyed employers reported that graduates were inadequately prepared for entry-level jobs.
The study recommends upgrading training delivery through the application of 4IR curriculum and technology in classrooms and training facilities in close collaboration between industry and training providers to strengthen workforce readiness. The survey of training institutions revealed limited use of advanced technologies such as virtual and augmented reality and online platforms for training delivery.
The study calls for new approaches to strengthen inclusion and social protection for entry-level workers, those at risk of job displacement, and those who need upskilling. According to IT-BPO employers in the Philippines, manual and administrative jobs which are typically held by women are likely to see the largest losses, while females in Cambodia’s garments industry are more likely to be affected.
To ensure the welfare of workers, the study calls for a strong focus on reskilling and upskilling programs, and incentives schemes for employers to retrain workers. The Career-Up Josei-Kin program in Japan, which subsidizes employers to train individuals not on regular contracts is identified as a good example.
While the coronavirus disease pandemic is accelerating digital transformation, the study finds that companies deploying 4IR technologies are likely to recover faster from the disruptions caused by the pandemic and be more resilient in the future.
Thailand: Growth in Jobs Critical for Sustained COVID-19 Recovery
Thailand’s economy was severely impacted by the COVID-19 pandemic and is estimated to have shrunk by 6.5 percent in 2020. Growth is projected to expand by 4.0 percent in 2021, according to Restoring Incomes; Recovering Jobs, the latest edition of the World Bank’s Thailand Economic Monitor,” launched today. The report stresses that sustained recovery in employment will be essential to helping the country bounce back in 2021 and 2022.
In 2020, weak global demand, the sharp decline in international tourist arrivals, and domestic mobility restrictions depressed goods and services exports and private consumption. Exports and private investment are estimated to have declined by 18.5 percent and 4.4 percent respectively, while household consumption declined by 1.3 percent.
The resulting declines in income have created economic hardship for many, though the Government has made good progress in implementing a substantial package of measures to support households and firms. Nevertheless, projections indicate that an additional 1.5 million people may have entered poverty in 2020 due to the economic impacts of COVID-19, based on a poverty line of US$5.50 (2011 PPP) per day.
This year, the economy is expected to recover gradually, despite the recent second outbreak of COVID-19, and growth is forecast to pick up further to 4.7 percent in 2022. However, the recovery remains vulnerable to downside risks, including from an extended resurgence of the pandemic resulting in a prolonged stagnation in tourism and domestic activity, a weaker-than-expected global recovery that could lead to continuing trade and supply chain disruptions, and high household debt levels.
The pandemic’s impact has had a significant impact on Thailand’s labor market, with a particularly large increase in unemployment among young people. Hours worked fell, as did monthly incomes. Hours worked have not fully recovered, and employment in several sectors including manufacturing remains smaller than a year ago. This means the labor market is in a vulnerable position to confront any future shocks including a resurgence of COVID-19.
“The COVID-19 crisis and its economic impact have highlighted a key vulnerability for Thailand: the declining number of working-aged people, which compounds the challenge of recovering the economic losses of the last year,” said Birgit Hansl, World Bank Country Manager for Thailand. “Improvements in employment, productivity and labor incomes, especially among the poor, will be necessary for a sustainable recovery.”
The report recommends that in the short term, the government put in place training programs to improve workers skills and provide financial support while they get back to work. Ongoing efforts are required to ensure that education and training matches the needs of employers.
In the longer term, the government can increase employment in the care sector, make childcare more accessible and decrease its cost to help increase female labor force employment. The report also recommends increasing the retirement age and putting in place performance-based compensation schemes and flexible working arrangements to extend the working lives of older people.
“The decline in the working age population will reduce labor supply and economic output over the coming decades. Good jobs will need to be created in high-productivity sectors associated with Thailand’s emerging knowledge economy. Policies to boost labor productivity and labor market participation of older people and women can help promote a sustainable recovery from COVID-19, while addressing challenges associated with an aging population,” according to Kiatipong Ariyapruchya, World Bank Senior Economist for Thailand.
The World Needs to Wake Up to Long-Term Risks
For the last 15 years the World Economic Forum’s Global Risks Report has been warning the world about the dangers of pandemics. In 2020, we saw the effects of ignoring preparation and ignoring long-term risks. The COVID-19 pandemic has not only claimed millions of lives, but it also widened long-standing health, economic and digital disparities. Billions of caregivers, workers and students – especially minorities who were disadvantaged before the pandemic – are now at risk of missing pathways to the new and fairer societies that the recovery could unlock. According to the Global Risks Report 2021, released today, these developments may further impede the global cooperation needed to address long-term challenges such as environmental degradation.
When it comes to technology access and digital skills, the gap between the “haves” and the “have nots” risks widening and challenging social cohesion. This will particularly affect young people worldwide, as this group faces its second global crisis in a generation and could miss out altogether on opportunities in the next decade.
Financial, digital and reputational pressures resulting from COVID-19 also threaten to leave behind many companies and their workforces in the markets of the future. While these potential disparities could cause societal fragmentation for states, an increasingly tense and fragile geopolitical outlook will also hinder the global recovery if mid-sized powers lack a seat at the global table.
Once again, environmental risks dominate by impact and likelihood, looking ahead towards the next decade. Societal fractures, uncertainty and anxiety will make it more difficult to achieve the coordination needed to address the planet’s continued degradation.
For the first time, the report also rates risks according to when respondents perceive they will pose a critical threat to the world. Clear and present dangers (0-2 years) reveal concern about lives and livelihoods – among them infectious diseases, employment crises, digital inequality and youth disillusionment. In the medium-term (3-5 years), respondents believe the world will be threatened by knock-on economic and technological risks, which may take several years to materialize – such as asset bubble bursts, IT infrastructure breakdown, price instability and debt crises. Existential threats (5-10 years) – weapons of mass destruction, state collapse, biodiversity loss and adverse technological advances – dominate long-term concerns.
“In 2020, the risk of a global pandemic became reality, something this report has been highlighting since 2006. We know how difficult it is for governments, business and other stakeholders to address such long-term risks, but the lesson here is for all of us to recognize that ignoring them doesn’t make them less likely to happen. As governments, businesses and societies begin to emerge from the pandemic, they must now urgently shape new economic and social systems that improve our collective resilience and capacity to respond to shocks while reducing inequality, improving health and protecting the planet. To help meet this challenge, next week’s event, The Davos Agenda, will mobilize global leaders to shape the principles, policies and partnerships needed in this new context,” said Saadia Zahidi, Managing Director at the World Economic Forum.
The report also reflects on the responses to COVID-19, drawing lessons designed to bolster global resilience. These lessons include formulating analytical frameworks, fostering risk champions, building trust through clear and consistent communication, and creating new forms of partnership. The key risks outlined in the report are complemented with recommendations to help countries, businesses, and the international community to act, rather than react, in the face of cross-cutting risks. The report closes with an overview of “frontier risks” – nine high-impact, low-probability events drawn from expert foresight exercises – including geomagnetic disruption, accidental wars and exploitation of brain-machine interfaces.
“The acceleration of the digital transformation promises large benefits, such as for example the creation of almost 100 million new jobs by 2025. At the same time however, digitalization may displace some 85 million jobs, and since 60% of adults still lack basic digital skills the risk is the deepening of existing inequalities,” said Peter Giger, Group Chief Risk Officer, Zurich Insurance Group. “The biggest long-term risk remains a failure to act on climate change. There is no vaccine against climate risks, so post-pandemic recovery plans must focus on growth aligning with sustainability agendas to build back better.”
“Economic and societal fallout from COVID-19 will profoundly impact the way organizations interact with clients and colleagues long after any vaccine rollout. As businesses transform their workplaces, new vulnerabilities are emerging. Rapid digitalization is exponentially increasing cyber exposures, supply chain disruption is radically altering business models, and a rise in serious health issues has accompanied employees’ shift to remote working,” said Carolina Klint, Risk Management Leader, Continental Europe, Marsh. “Every business will need to strengthen and constantly review their risk mitigation strategies if they are to improve their resilience to future shocks.”
“The pandemic in 2020 was a stress-test that shook the foundations of economies and societies worldwide. Rebuilding resilience to systemic shocks will require significant funding, international cooperation and greater social cohesion. Resilience will also hinge on the continued growth in connectivity worldwide, as we know that economies that digitized early performed relatively better in 2020,” said Lee Hyung-hee, President, Social Value Committee, SK Group. “If the continued deployment of 5G and AI is to emerge as an engine of growth, however, we must urgently bridge digital divides and address ethical risks.”
The Global Risks Report 2021 has been developed with the invaluable support of the World Economic Forum’s Global Risks Advisory Board. It also benefits from ongoing collaboration with its Strategic Partners Marsh McLennan, SK Group and Zurich Insurance Group and its academic advisers at the Oxford Martin School (University of Oxford), the National University of Singapore and the Wharton Risk Management and Decision Processes Center (University of Pennsylvania).
