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.

UN Rideshare app makes its debut at Asia-Pacific Clean Air Week

MD Staff



A new UN Rideshare mobile application, brainchild of the Bangkok-based UN Office of Information and Communication Technology, will be launched and demonstrated during Clean Air Week, which will take place in Bangkok from 19-23 March. The app is among a number of breakthrough innovations that will be featured during the week, including bicycles from Mobike, pollution sensors from the Clarity Movement, and a virtual reality experience with pollution, including air and plastic pollution.

Focused on solutions, Clean Air Week will bring together leaders from governments and the private sector, experts, civil society, top influencers and celebrities to discuss the latest science and best approaches to tackling pollution at the national and local levels. UN Environment Goodwill Ambassador for India Dia Mirza and UN Environment Patron of Clean Air Vijay Shekar Sharma, founder of India’s largest mobile-first financial services conglomerate Paytm, will also attend the meeting.

“We all know that air pollution is devastating to our health and environment and has grave consequences for economies,” said Dechen Tsering, Regional Representative and Regional Director, UN Environment Asia Pacific. “We are the region that feels this most acutely and it is paramount that we act on this. Last year countries around the world resolved to clean up our air, land and water at the UN Environment Assembly. Our hope is that the week will be a catalyst for transformative solutions so that people in this region, if I can use a pun, can breathe easy.”

The Rideshare application, which is currently in beta testing phase, will likely be available in App stores in April. It will allow – and hopefully encourage – UN staff to leave their vehicles at home and pool their travel to and from work.

“We are now testing it in the UN and it can be applied to other communities and international organizations,” said Lee Hwayun, Project Associate at the UN Office of Information and Communication Technology. “It is aligned with climate change and sustainable development goals in reducing emissions and resource use. It is also good for community bonding as it offers people an opportunity to meet others in the UN and in the community.”

Riast Ullah, also of the UN Office of Information and Communication Technology, said that that safety was an element that was factored in designing the app. “We centred the design around communities because if you know the person is from the same organization or community, you feel safe taking a ride with him or her,” he added.

According to Ullah, the application was designed to make it easy for vehicle owners and passengers to use. People with vehicles add their vehicle license, number they can carry, destination and route they are taking, including stop points. Passengers select the time they want to go and the system sends them a notice. Vehicle owners can also send notes.

Clean Air Week Asia-Pacific will feature a series of events, starting with a Low Carbon Lifestyles Challenge Clinic and a workshop on pollution and health assessments. The week will also include sessions on cleaner fuel and vehicles, a dialogue on doubling fuel economy, and the Asia-Pacific Clean Air Partnership Joint Forum, which will have side events that look at advancing air quality monitoring with emerging technologies.

WEF Launches Tech for Integrity Platform in Anti-Corruption Drive

MD Staff



The World Economic Forum’s Partnering Against Corruption Initiative (PACI) has launched a Tech for Integrity platform to accelerate anti-corruption efforts and reduce the time needed to make tangible impact. This digital platform will leverage tech innovators and partnerships with multistakeholders, including Citi, the Inter-American Development Bank, Transparency International and others to rebuild trust and integrity globally.

Corruption impedes economic growth, contributes to social inequality and obstructs innovation. As such, global leaders of business and government are looking for better ways to improve integrity and transparency across sectors. Technology has emerged as the greatest ally of transparency and a critical tool against corruption.

Four nascent technologies in particular – blockchain, big data analytics, artificial intelligence and e-governance – hold significant promise for businesses and governments to safeguard primary points of vulnerability. Given the early stages of these technologies, the most appropriate tools remain difficult to identify and source by the governments, businesses and civil society actors that need them. Understanding the role of technology and connecting leaders of government and business with the resources they need to promote integrity has a huge potential to create downstream benefits for every aspect of society.

The T4I platform, emerging out of PACI’s Future of Trust and Integrity project, is aimed at providing technological solutions faced by stakeholders addressing corruption. Last year, Citi, in collaboration with public and private sector allies, created and launched the Tech for Integrity Challenge to source innovative solutions to fight corruption. Citi, Mastercard, Microsoft, IBM, PwC, Clifford Chance and Let’s Talk Payments successfully sourced 1,000 registrations, and together with 80 other allies selected 96 finalists to present their ideas at six Demo Days around the world.

“Citi is excited that PACI will continue the T4I mission to solve issues of integrity, continue the collaboration of this fantastic ecosystem and build further momentum in adopting these solutions,” said Julie Monaco, Global Head of the Public Sector Group in Citi’s Corporate and Investment Banking division. “We look forward to working with WEF and PACI to further develop and implement solutions that will make a global impact.”

PACI’s next generation of this platform provides three intersecting spaces to drive thought leadership, networks and increase impact:

Knowledge accelerator – Driven by public-private cooperation, the knowledge accelerator is a dynamic digital repository of information that aims to foster communication and collaboration to deepen understanding of how technologies can better address corruption.

Synergy lab –The synergy lab will help leaders of government, business and civil society identify their specific needs and connect those leaders with innovators providing the most appropriate technology solutions to address those needs.

Impact initiatives – In concert with international organizations, the private sector and civil society, the impact initiatives will share best practices on available solutions, evaluate existing implementation projects, as well as directly engage with such projects to effectively demonstrate how to build solutions into government and business processes to promote trust and integrity.

“Technology is becoming one of our greatest allies in the effort to disrupt corruption,” said Luis Alberto Moreno. President, Inter-American Development Bank. “Coupled with political resolve, the digital revolution can help us reach our goals of greater transparency and accountability in government much faster and more efficiently than we thought possible. The IDB will continue to support this important and timely initiative.”

“New technologies offer great opportunities to enhance participation, access to information and the possibility to monitor public policies. Nevertheless, it is misguided to believe that technology will solve all corruption problems. We have to be careful not to introduce tools that might strengthen the risks of anonymity which are essential in corrupt deals,” said Delia Ferreira Rubio, Chair of Transparency International, a key partner with the PACI project responsible for the new platform. “The Tech for Integrity platform provides a space to debate important issues and share technologies to increase transparency.”

“The Fourth Industrial Revolution can only deliver on its potential if leaders know when, where and how to use the tools emerging from it,” said Olivier Schwab, Managing Director and Head of Business Engagement at the World Economic Forum. “PACI’s Tech for Integrity platform connects innovators and implementers to foster a better understanding of the drivers of trust and how to utilize the latest technologies to rebuild integrity.”

New Principles to Make Machine Learning More Human

MD Staff



Strong standards are urgently needed to prevent discrimination and marginalization of humans in artificial intelligence. This is the finding of a new white paper, How to Prevent Discriminatory Outcomes in Machine Learning, published today by the World Economic Forum’s Global Future Council on Human Rights.

The paper has been produced after a long consultation period and is based on research and interviews with industry experts, academics, human rights professionals and others working at the intersection of machine learning and human rights. The key recommendation for developers and all businesses looking to use machine learning is to prioritize non-discrimination by adopting a framework based on four guiding principles: active inclusion; fairness; right to understanding; and access to redress.

Recent examples of how machine learning has failed to prevent discrimination include:

Loan services – applicants from rural backgrounds, who have less digital infrastructure, could be unfairly excluded by algorithms trained on data points captured from more urban populations

Criminal justice – the underlying data used to train an algorithm may be biased, reflecting a history of discrimination.

Recruitment – applications might filter out people from lower-income backgrounds, those who attended less prestigious schools, based on factors such as educational attainment status

“We encourage companies working with machine learning to prioritize non-discrimination along with accuracy and efficiency to comply with human rights standards and uphold the social contract,” said Erica Kochi, Co-Chair of the Global Future Council for Human Rights and Co-Founder of UNICEF Innovation.

“One of the most important challenges we face today is ensuring we design positive values into systems that use machine learning. This means deeply understanding how and where we bias systems and creating innovative ways to protect people from being discriminated against,” said Nicholas Davis, Head of Society and Innovation, Member of the Executive Committee, World Economic Forum.

The white paper is part of a broader workstream within the Global Future Council looking at the social impact of machine learning, such as the way it amplifies longstanding problems related to unequal access.
