Argentina Applies Nuclear Technology to Water

In Argentina, like in many parts of the world, water is at risk of over-exploitation and contamination. To protect it, scientists are studying its most invisible details with the help of nuclear technology and the support of the IAEA.

“Most of the fresh, usable water in the world is in the ground, but most of the water that’s available to us is surface water,” said Douglas Kip Solomon, professor of Geology and Geophysics at the University of Utah, who is helping Argentinian experts map their water with the help of the IAEA. “It is extremely important that we understand the interactions between surface water and groundwater so we know how to properly manage these resources and protect them.”

With the help of nuclear techniques, scientists can determine the quantity and quality of their water supplies. They use naturally occurring isotopes as tracers to find out where groundwater comes from, if it is recent or old, if it is being recharged or polluted and how it travels.

The science behind this is called isotope hydrology — a discipline that, according to expert Solomon, “is one of the most powerful, trustworthy tools available to assess groundwater thoroughly.”

“We look to find out exactly how water moves inside aquifers, how it interacts with rivers, and how much of it is left,” said Sandra Ibáñez, isotope hydrologist at the University of Cuyo, Mendoza, who is participating in an IAEA technical cooperation project in the country. The IAEA supports scientists around the world on isotope hydrology, sending experts to the field and training local hydrologists in the use of these isotopic techniques.

Since early 2016, Argentinian isotope hydrologists have been gathering and interpreting data from two strategic regions with the help of the IAEA. The idea is for policy makers to use this information and design improved water management models —hydrological models— for these regions.

“Argentina is lucky to have a very good amount of water per inhabitant, but this water is distributed very unevenly across the country,” said Daniel Cicerone, environmental manager at Argentina’s National Atomic Energy Commission (CNEA). “In some regions, finding out if the water we are using on a daily basis is regularly recharged, running out, or at risk of contamination can make the difference between poverty and prosperity.”

Hidden reserves

The two regions were selected for different reasons. In the first —the arid valley of Mendoza, western Argentina— people rely on the fresh underground water of the aquifers of Uspallata, Yaguaráz and other, smaller ones. Authorities are keen to find out whether this water is being sustainably extracted, and if the aquifers have enough capacity to support more water use.

“We need water for everything: to wash our tools, to keep them clean. Water is our daily bread,” said Sergio Cirauqui, who works in a kayaking and rafting adventure shop off the top of a mountain in Uspallata. “But we are very conscious about the fact that water is a finite resource and that we have to take care of it. And as a finite resource, we should make an almost sacred use of it.”

Argentinian isotope hydrologists have been hiking the mountains and plains of Mendoza for more than a year, collecting water from wells, lakes and rivers accompanied by international and IAEA experts. Back in their labs, they are interpreting the results to paint a clearer picture of what is available.

Based on data such as the recharge rate of water in aquifers, policymakers are in a better position to establish rules for the use of water for drinking, agriculture and industry. Knowing that surface water is infiltrating groundwater, for example, can lead to stricter regulations on acceptable pollution levels.

“Once we have the results, we can decide what business activities to develop in Mendoza,” said Juan Andrés Pina, Deputy Director of Groundwater Division at Mendoza’s General Department of Irrigation.

The second region under study is a streambed in Los Gigantes, Córdoba, an old mining complex about 700 km West of Buenos Aires. Here, Argentinian authorities are implementing an environmental remediation project, working side-by-side with isotope hydrologists to find out more about the quality of the groundwater and its potential vulnerability to contamination.

After the two uranium mines closed, scientists and authorities were vigilant about groundwater in the area. Through the IAEA project, scientists are now monitoring whether water recharging the San Roque lake reservoir, a source for human consumption in the city of Córdoba, is clean and safe.

And while they have found that uranium levels in the groundwater are safe, they are working to find the exact origin and movement of groundwater, including recharge areas, age, volume, behaviour, and vulnerability to future contamination.

“This interdisciplinary and interinstitutional study will help authorities improve the conceptual model and hydrological understanding of the area and strengthen the remediation of the site,” said Daniel Martínez, geologist and researcher at the National Council of Scientific and Technological Research (COCINET).

The regional technical cooperation projects have been essential in transferring knowledge and technology to national and local institutions, said Raúl Ramírez García, Section Head at the IAEA’s Technical Cooperation Department.

“The new information provided by isotopic techniques will help monitor the water resources and support the kind of decision making that will lead to social and economic benefits for the population of these regions,” Ramírez García said.

The Science

Every water molecule has hydrogen and oxygen atoms, but these are not all the same: some atoms are lighter and some are heavier.

“All natural waters have a different hydrogen and oxygen isotopic composition,” said IAEA isotope hydrologist Lucía Ortega. “We use this isotopic composition as the fingerprints of water.”

As water evaporates from the sea, molecules with lighter isotopes tend to preferentially rise. As rain falls, molecules with heavier isotopes fall sooner. The further the cloud moves inland, the higher proportion of isotopes with light isotopes in rain.

When water falls to the earth, it fills lakes, rivers and aquifers, Ortega said. “By measuring the difference in the proportions between the light and heavy isotopes, we can estimate the origin of different waters.”

In addition, naturally occurring radioactive isotopes present in water such as tritium, carbon 14 and noble gases can be used to estimate groundwater age — from a few days to one millennia. When groundwater is found to be tens of thousands of years old, this means that the water flow is very slow and that, if inappropriately extracted, can take tens of thousands of years to replenish again.

“And this is key to help us assess the quality, quantity and sustainability of water,” she said.

Asia Needs a Region-Wide Approach to Harness Fintech’s Full Potential

Asia’s policy makers should strengthen cooperation to harness the potential of new financial technologies for inclusive growth. At the same time, they should work together to ensure they can respond better to the challenges posed by fintech.

New technologies such as mobile banking, big data, and peer-to-peer transfer networks are already extending the reach of financial services to those who were previously unbanked or out of reach, boosting incomes and living standards. Yet, fintech also comes with the risk of cyber fraud, data security, and privacy breaches. Disintermediation of fintech services or concentration of services among a few providers could also pose a risk to financial stability.

These and other issues were discussed at the High-Level Policy Dialogue on Regional Cooperation to Support Innovation, Inclusion, and Stability in Asia, organized by the Asian Development Bank (ADB), Bank Indonesia, and the ASEAN+3 Macroeconomic Research Office (AMRO).

The panel comprised Ms. Neav Chanthana, Deputy Governor of the National Bank of Cambodia; Mr. Diwa Guinigundo, Deputy Governor of Bangko Sentral ng Pilipinas; Ms. Mary Ellen Iskenderian, President and Chief Executive Officer of Women’s World Banking; Mr. Ravi Menon, Managing Director of the Monetary Authority of Singapore; Mr. Takehiko Nakao, President of ADB; Mr. Abdul Rasheed, Deputy Governor, Bank Negara Malaysia, and Mr. Veerathai Santiprabhob, Governor of the Bank of Thailand. Mr. Mirza Adityaswara, Senior Deputy Governor of Bank Indonesia, gave the opening remarks at the conference and Ms. Junhong Chang, Director of AMRO, gave the welcome remarks.

“Rapidly spreading new financial technologies hold huge promise for financial inclusion,” said Mr. Nakao. “We must foster an enabling environment for the technologies to flourish and strengthen regional cooperation to build harmonized regulatory standards and surveillance systems to prevent international money laundering, terrorism financing, and cybercrimes.”

“Technology is an enabler that weaves our economies and financial systems together, transmitting benefits but also risks across borders,” said Ms. Chang. “Given East Asia’s rapid economic growth, understanding and managing the impact of technology in our financial systems is essential for policymakers to maintain financial stability.”

“Asia, including Indonesia, is an ideal place for fintech to flourish,” said Mr. Adityaswara. “In Indonesia’s case, there are more than a quarter of a billion people living on thousand of islands, waiting to be integrated with the new technology; young people eager to enter the future digital world; more than fifty million small and medium-sized enterprises which can’t wait to get on board with e-commerce; a new society driven by a dynamic, democratic middle class which views the digital economy as something as inevitable as evolution.”

Despite Asia’s high economic growth in recent years, the financial sector is still under-developed in some countries. Fewer than 27% of adults in developing Asia have a bank account, well below the global median of 38%. Meanwhile, just 84% of firms have a checking or savings account, on a par with Africa but below Latin America’s 89% and emerging Europe’s 92%.

Financial inclusion could be increased through policies to promote financial innovation, by boosting financial literacy, and by expanding and upgrading digital infrastructure and networks. Regulations to prevent illegal activities, enhance cyber security, and protect consumers’ rights and privacy, would also build confidence in new financial technologies.

Cutting-edge tech a ‘double-edged sword for developing countries’

MD Staff

Published

The latest technological advances, from artificial intelligence to electric cars, can be a “double-edged sword”, says the latest UN World Economic and Social Survey (WESS 2018), released on Monday.

The over-riding message of the report is that appropriate, effective policies are essential, if so-called “frontier technologies” are to change the world for the better, helping us to achieve the Sustainable Development Goals (SDGs) and addressing climate change: without good policy, they risk exacerbating existing inequality.

Amongst several positive indicators, WESS 2018 found that the energy sector is becoming more sustainable, with renewable energy technology and efficient energy storage systems giving countries the opportunity to “leapfrog” existing, often fossil fuel-based solutions.

The wellbeing of the most vulnerable is being enhanced through greater access to medicines, and millions in developing countries now have access to low-cost financial services via their mobile phones.

Referring to the report, UN Secretary-General António Guterres said that “good health and longevity, prosperity for all and environmental sustainability are within our reach if we harness the full power of these innovations.”

However, the UN chief warned of the importance of properly managing the use of new technologies, to ensure there is a net benefit to society: the report demonstrates that unmanaged implementation of developments such as artificial intelligence and automation can improve efficiency but also destroy quality jobs.

“Clearly, we need policies that can ensure frontier technologies are not only commercially viable but also equitable and ethical. This will require a rigorous, objective and transparent ongoing assessment, involving all stakeholders,” Mr. Guterres added

The Survey says that proactive and effective policies can help countries to avoid pitfalls and minimize the economic and social costs of technology-related disruption. It calls for regulation and institutions that promote innovation, and the use of new technologies for sustainable development.

With digital technology frequently crossing borders, international cooperation, the Survey shows, is needed to bring about harmonized standards, greater flexibility in the area of intellectual property rights and ensuring that the market does not remain dominated by a tiny number of extremely powerful companies.

Here, the UN has a vital role to play, by providing an objective assessment of the impact that emerging technologies have on sustainable development outcomes – including their effects on employment, wages and income distribution – and bringing together people, business and organizations from across the world to build strong consensus-led agreements.

Our Trust Deficit with Artifical Intelligence Has Only Just Started

Published

“We suffer from a bad case of trust-deficit disorder,” said UN Secretary-General António Guterres in his recent General Assembly speech. His diagnosis is right, and his focus on new technological developments underscores their crucial role shaping the future global political order. Indeed, artificial intelligence (AI) is poised to deepen the trust-deficit across the world.

The Secretary-General, echoing his recently released Strategy on New Technologies, repeatedly referenced rapidly developing fields of technology in his speech, rightly calling for greater cooperation between countries and among stakeholders, as well as for more diversity in the technology sector. His trust-deficit diagnosis reflects the urgent need to build a new social license and develop incentives to ensure that technological innovation, in particular AI, is deployed safely and aligned with the public interest.

However, AI-driven technologies do not easily fit into today’s models of international cooperation, and will in fact tend to undermine rather than enforce global governance mechanisms. Looking at three trends in AI, the UN faces an enormous set of interrelated challenges.

AI and Reality

First, AI is a potentially dominating technology whose powerful – both positive and negative –implications will be increasingly difficult to isolate and contain. Engineers design learning algorithms with a specific set of predictive and optimizing functions that can be used to both empower or control populations. Without sophisticated fail-safe protocols, the potential for misuse or weaponization of AI is pervasive and can be difficult to anticipate.

Take Deepfake as an example. Sophisticated AI programs can now manipulate sounds, images and videos, creating impersonations that are often impossible to distinguish from the original. Deep-learning algorithms can, with surprising accuracy, read human lips, synthetize speech, and to some extent simulate facial expressions. Once released outside of the lab, such simulations could easily be misused with wide-ranging impacts (indeed, this is already happening at a low level). On the eve of an election, Deepfake videos could falsely portray public officials being involved in money-laundering or human rights abuses; public panic could be sowed by videos warning of non-existent epidemics or cyberattacks; forged incidents could potentially lead to international escalation.

The capacity of a range of actors to influence public opinion with misleading simulations could have powerful long-term implications for the UN’s role in peace and security. By eroding the sense of trust and truth between citizens and the state—and indeed amongst states—truly fake news could be deeply corrosive to our global governance system.

AI Reading Us

Second, AI is already connecting and converging with a range of other technologies—including biotech—with significant implications for global security. AI systems around the world are trained to predict various aspects of our daily lives by making sense of massive data sets, such as cities’ traffic patterns, financial markets, consumer behaviour trend data, health records and even our genomes.

These AI technologies are increasingly able to harness our behavioural and biological data in innovative and often manipulative ways, with implications for all of us. For example, the My Friend Cayla smart doll sends voice and emotion data of the children who play with it to the cloud, which led to a US Federal Trade Commission complaint and its ban in Germany. In the US, emotional analysis is already being used in the courtroom to detect remorse in deposition videos. It could soon be part of job interviews to assess candidates’ responses and their fitness for a job.

The ability of AI to intrude upon—and potentially control—private human behaviour has direct implications for the UN’s human rights agenda. New forms of social and bio-control could in fact require a reimagining of the framework currently in place to monitor and implement the Universal Declaration of Human Rights, and will certainly require the multilateral system to better anticipate and understand this quickly emerging field.

AI as a Conflict Theatre

Finally, the ability of AI-driven technologies to influence large populations is of such immediate and overriding value that it is almost certain to be the theatre for future conflicts. There is a very real prospect of a “cyber race” in which powerful nations and large technology platforms enter into open competition for our collective data as the fuel to generate economic, medical and security supremacy across the globe. Forms of “cyber-colonization” are increasingly likely, as powerful states are able to harness AI and biotech together to understand and potentially control other countries’ populations and ecosystems.

Towards Global Governance of AI

Politically, legally and ethically, our societies are not prepared for the deployment of AI. The UN, established many decades before the emergence of these technologies, is in many ways poorly placed to develop the kind of responsible governance that will channel AI’s potential away from these risks and towards our collective safety and wellbeing. In fact, the resurgence of nationalist agendas across the world may point to a dwindling capacity of the multilateral system to play a meaningful role in the global governance of AI. Major corporations and powerful member states may see little value in bringing multilateral approaches to bear on what they consider lucrative and proprietary technologies.

There are, however, some important ways in which the UN can help build the kind of collaborative, transparent networks that may begin to treat our “trust-deficit disorder.” The Secretary-General’s recently-launched High-Level Panel on Digital Cooperation, is already working to build a collaborative partnership with the private sector and establish a common approach to new technologies. Such an initiative could eventually find ways to reward cooperation over competition, and to put in place common commitments to using AI-driven technologies for the public good.

Perhaps the most important challenge for the UN in this context is one of relevance, of re-establishing a sense of trust in the multilateral system. But if the above trends tell us anything, it is that AI-driven technologies are an issue for every individual and every state, and that without collective, collaborative forms of governance, there is a real risk that it will be a force that undermines global stability.
