At 7:18 a.m. on May 15, 2021, the Tianwen-1 space mission entered Mars’ atmosphere and successfully landed in the planned area (Utopia Planitia) while the orbiting station carried out its task around the planet.

The People’s Republic of China is the third country to reach Mars, and the second one to have a mobile exploration vehicle (rover) operating on the planet’s surface. The first country to arrive on Mars was the Soviet Union on December 2, 1971 with two space probes: Mars 2 (November 27, 1971) was destroyed by a storm of debris during landing, while Mars 3 landed, but communication lasted only 14.5 seconds and ceased in an unexplainable manner. It was then the turn of the United States, whose Viking 1 successfully landed on Mars on July 20, 1976.

The Tianwen-1 space mission comprises two parts: the orbital station and the landing module. At the predicted time, the Tianwen-1 spacecraft successfully completed the separation between the two devices. Three hours later, the landing module successfully crossed Mars’ atmosphere and softly landed on the surface of the red planet. About thirty minutes after separation, the orbiting station ascended and returned to circularly traverse Mars.

In this Mars exploration mission, the orbiting station is not only a special interstellar vehicle, but it is also a powerful communications relay station that builds a bridge between Mars and the Earth, and is responsible for remote sensing exploration of Mars’ surface, in view of creating a mapping of the planet.

The orbiting station carries two solar cell devices, an antenna for data transmission and two antennas for mutual information transfer. When the orbiting station performs data transmission tasks, the solar cells need to be directed towards our star to ensure continuous power supply. At the same time, the high-frequency antenna is needed to track the route between the Earth and the module to establish a continuous data link bridge. Thus, the orbiting station must simultaneously establish a synchronized, high-precision pointing control of the three targets: module (then rover), Earth and sun.

Chinese designers have also made plans for possible link disruptions, while ensuring high-precision control of the antenna pointing.

It is an autonomous recovery strategy in case the communication link is disrupted. If this happens, a detector will operate autonomously and the antenna will be returned to Earth with the restoration of telecommunications. The process is carried out independently of conventional devices.

Xi Jinping, General Secretary of the Central Committee of the Communist Party of China (CPC), as well as President of the State and Chairman of the Central Military Commission, sent a message of congratulations on behalf of the Central Committee of the Communist Party of China, the State Council and the Central Military Commission to extend warm congratulations and sincere greetings to all the scientists who participated in China’s first exploration mission to Mars.

In his message of congratulations President Xi Jinping has underlined that the landing of Tianwen-1 on Mars is an important step in the interstellar exploration journey, thus making the leap from the Earth-Moon system to the interplanetary system, leaving a Chinese mark on Mars: a milestone in the development of the country’s aerospace industry that challenges and pursues excellence by placing China in the most advanced ranks in the field of planetary exploration.

President Xi Jinping has stressed the hope that we could continue to work hard, to carefully organize and implement the scientific exploration of Mars, and to insist on technological self-sufficiency, so as to advance further major space projects and accelerate the construction of new launchers, for achievements that will develop the noble cause of solving the mysteries of the universe and hence promote mankind’s peace and development.

China’s first Mars exploration mission was established in 2016 with plans to orbit, land and explore the planet with a rover.

The Tianwen-1 space mission was successfully launched by the Long March 5 carrier rocket in Wenchang (Hainan) on July 23, 2020, and reached Mars orbit on February 10, 2021 – fourteen days after beginning to perform the functions of an artificial satellite of the planet. Upon entering Mars orbit, it began a three-month exploration series, thus setting the stage for a regular landing.

The China National Space Administration (Guojia Hangtian Ju) has carried out relevant project cooperation with the European Space Agency, as well as with Argentina, France, Austria and other national and international space organizations. Jointly with other organizations, it will contribute to improve the understanding of the origin of life.

China regards hard power as economic, scientific and technological strength, and soft power is aimed at people’s quality of life. Compared to lunar exploration missions, the Mars mission presents more technical challenges. The Mars rover led by Tianwen-1 is the result of China’s independent innovation and uses national designs of carrier rocket systems.

On the other hand, with the strengthening of economic power and the improvement of education level, China has become the world’s second largest investor in research and development, as well as knowledge. The Chinese Academy of Sciences team, in charge of the space mission, has an average age of only 33 years, showing that scientific research talents are younger and that the quality of the new generation people has improved.

Although space projects such as Mars exploration are expensive, they are a platform where governments, businesses, schools, and research institutes focus. Technological breakthroughs in various fields – although currently being sometimes purely abstract (especially in mathematics and theoretical physics) – are capable of directing future development in any field, as Professor Zvi Artstein teaches us. Rocket manufacturing, satellite communications, ground equipment and computer development have all huge market potential, but they have always stemmed from mere conceptual speculation.

The Mars exploration project involves artificial intelligence, materials manufacturing, communications technology, and so on and so forth. Such innovations can be applied to the development of industries aimed at producing goods that improve every person’s daily life.

As usual, some foreign media believe that China’s entry into the ranks of Mars exploration is due to the intensification of competition for space dominance and is therefore designed to seize the opportunity of becoming a super power and strengthening the military potential.

The “Chinese threat theory” has been mentioned again. In simple words: if others conquer space, they do it only out of goodness towards mankind and for the good of the world, while if China does so it is only to dominate the planet. Old-fashioned and pathetic parameters, reminiscent of the science fiction movies of the 1960s that hid the Soviet villain under the guise of the ruthless alien even horrible to see.

In response, the Chinese Ministry of Foreign Affairs has stated that China’s exploration of Mars is an open scientific project, and the Chinese government is willing to cooperate with other countries in the field of space and its peaceful use, thus promoting the building of a community with a shared future for all Earth’s inhabitants.

There is no doubt that the progress of science and aerospace technology have created a sense of pride and belonging among citizens and has strengthened China’s national unity. In the long run, Chinese researchers will contribute with technology and cognitive wisdom also to manned space missions, as envisaged by a project outlined by Prof. Wang Xiaojun, Rector of the China Academy of Launch Vehicle Technology (CALT) on September 18, 2020.

Advisory Board Co-chair Honoris Causa Professor Giancarlo Elia Valori is an eminent Italian economist and businessman. He holds prestigious academic distinctions and national orders. Mr. Valori has lectured on international affairs and economics at the world’s leading universities such as Peking University, the Hebrew University of Jerusalem and the Yeshiva University in New York. He currently chairs “International World Group”, he is also the honorary president of Huawei Italy, economic adviser to the Chinese giant HNA Group. In 1992 he was appointed Officier de la Légion d’Honneur de la République Francaise, with this motivation: “A man who can see across borders to understand the world” and in 2002 he received the title “Honorable” of the Académie des Sciences de l’Institut de France. “

From nanotechnology to solar power: Solutions to drought

Published

on

While the drought has intensified in Iran and the country is facing water stress, various solutions from the use of solar power plants to the expansion of watershed management and nanotechnology are offered by experts and officials.

Iran is located in an arid and semi-arid region, and Iranians have long sought to make the most of water.

In recent years, the drought has intensified making water resources fragile and it can be said that we have reached water bankruptcy in Iran.

However, water stress will continue this fall (September 23-December 21), and the season is expected to be relatively hot and short of rain, according to Ahad Vazifeh, head of the national center for drought and crisis management.

In such a situation, officials and experts propose various solutions for optimal water management.

Alireza Qazizadeh, a water and environment expert, referring to 80 percent of the arid regions in the country, said that “Iran has one percent of the earth’s area and receives only 36 percent of renewable resources.

The country receives 250 mm of rainfall annually, which is about 400 billion cubic meters, considering 70 percent evaporation, there is only 130 billion cubic meters of renewable water and 13 billion cubic meters of input from border waters.”

Referring to 800 ml of average rainfall and 700 mm of global evaporation, he noted that 70 percent of rainfall in Iran occurs in only 25 percent of the country and only 25 percent rains in irrigation seasons.

Pointing to the need for 113 billion cubic meters of water in the current year (began on March 21), he stated that “of this amount, 102 billion is projected for agricultural use, 7 percent for drinking and 2 percent for industry, and at this point water stress occurs.

In 2001, 5.5 billion cubic meters of underground resources were withdrawn annually, and if we consider this amount as 20 years from that year until now, it means that we have withdrawn an equivalent of one year of water consumption from non-renewable resources, which is alarming.”

The use of unconventional water sources can be effective in controlling drought, such as rainwater or river runoff, desalinated water, municipal wastewater that can be reused by treatment, he concluded.

Rasoul Sarraf, the Faculty of Materials at Shahid Modarres University, suggests a different solution and states that “To solve ease water stress, we have no choice but to use nanotechnology and solar power plants.

Pointing to the sun as the main condition for solar power plant, and while pointing to 300 sunny days in the country, he said that at the Paris Convention, Iran was required to reduce emissions by 4 percent definitively and 8 percent conditionally, which will only be achieved by using solar power plants.

Hamidreza Zakizadeh, deputy director of watershed management at Tehran’s Department of Natural Resources and Watershed Management, believes that watershed management can at least reduce the effects of drought by managing floods and extracting water for farmers.

Amir Abbas Ahmadi, head of habitats and regional affairs of Tehran Department of Environment, also referring to the severe drought in Tehran, pointed to the need to develop a comprehensive plan for water management and said that it is necessary to cooperate with several responsible bodies and develop a comprehensive plan to control the situation.

He also emphasizes the need to control migration to the capital, construction, and the implementation of the Comprehensive Plan of Tehran city.

While various solutions are proposed by officials and experts to manage water and deal with drought, it is necessary for the related organizations to work together to manage the current situation.

Mohammad Reza Espahbod, an expert in groundwater resources, also suggested that while the country is dealing with severe drought due to improper withdrawal of groundwater and low rainfall, karst water resources can supply the whole water needed by the country, only if managed.

Iran is the fifth country in the world in terms of karst water resources, he stated.

Qanats can also come efficient to contain water scarcity due to relatively low cost, low evaporation rates, and not requiring technical knowledge, moreover, they proved sustainable being used in perpetuity without posing any damages to the environment.

According to the Ministry of Energy, about 36,300 qanats have been identified in Iran, which has been saturated with water for over 2,000 years.

In recent years, 3,800 qanats have been rehabilitated through watershed and aquifer management, and people who had migrated due to water scarcity have returned to their homes.

Water resources shrinking

Renewable water resources have decreased by 30 percent over the last four decades, while Iran’s population has increased by about 2.5 times, Qasem Taqizadeh, deputy minister of energy, said in June.

The current water year (started on September 23, 2020) has received the lowest rain in the past 52 years, so climate change and Iran’s arid region should become a common belief at all levels, he lamented.

A recent report by Nature Scientific Journal on Iran’s water crisis indicates that from 2002 to 2015, over 74 billion cubic meters have been extracted from aquifers, which is unprecedented and its revival takes thousands of years along with urgent action.

Three Iranian scientists studied 30 basins in the country and realized that the rate of aquifer depletion over a 14-year period has been about 74 billion cubic meters, which is recently published in Nature Scientific Journal.

Also, over-harvesting in 77 percent of Iran has led to more land subsidence and soil salinity. Research and statistics show that the average overdraft from the country’s aquifers was about 5.2 billion cubic meters per year.

Mohammad Darvish, head of the environment group in the UNESCO Chair on Social Health, has said that the situation of groundwater resources is worrisome.

Technology and crime: A never-ending cat-and-mouse game

Published

on

Is technology a good or bad thing? It depends on who you ask, as it is more about the way technology is used. Afterall, technology can be used by criminals but can also be used to catch criminals, creating a fascinating cat-and-mouse game.

Countless ways technology can be used for evil

The first spear was used to improve hunting and to defend from attacking beasts. However, it was also soon used against other humans; nuclear power is used to produce energy, but it was also used to annihilate whole cities. Looking at today’s news, we’ve learned that cryptocurrencies could be (and are) used as the preferred form of payments of ransomware since they provide an anonymous, reliable, and fast payment method for cybercriminals.

Similarly, secure phones are providing criminal rings with a fast and easy way to coordinate their rogue activities. The list could go on. Ultimately, all technological advancements can be used for good or evil. Indeed, technology is not inherently bad or good, it is its usage that makes the difference. After all, spears served well in preventing the extinction of humankind, nuclear power is used to generate energy, cryptocurrency is a promise to democratize finance, and mobile phones are the device of choice of billions of people daily (you too are probably reading this piece on a mobile).

However, what is new with respect to the past (recent and distant) is that technology is nowadays much more widespread, pervasive, and easier to manipulate than it was some time ago. Indeed, not all of us are experts in nuclear material, or willing and capable of effectively throwing a spear at someone else. But each of us is surrounded by, and uses, technology, with a sizeable part of users also capable of modifying that technology to better serve their purposes (think of computer scientists, programmers, coding kids – technology democratization).

This huge reservoir of people that are capable of using technology in a way that is different from what it was devised for, is not made of just ethical hackers: there can be black hats as well (that is, technology experts supporting evil usages of such technology). In technical terms, the attack vector and the security perimeter have dramatically expanded, leading to a scenario where technology can be easily exploited for rogue purposes by large cohorts of people that can attack some of the many assets that are nowadays vulnerable – the cybersecurity domain provides the best example for the depicted scenario. 

Fast-paced innovation and unprecedented threats

What is more, is that technology developments will not stop. On the contrary, we are experiencing an exponentially fast pace in technology innovation, that resolves in less time between technology innovations cycles that, while improving our way of living, also pave the way for novel, unprecedented threats to materialize. For instance, the advent of quantum computers will make the majority of current encryption and digital signature methods useless and what was encrypted and signed in the past, exposed.

The tension between legitimate and illegitimate usages of technology is also heating up. For instance, there are discussions in the US and the EU about the need for the provider of ICT services to grant the decryption keys of future novel secure applications to law enforcement agencies should the need arise –a debatable measure.

However, technology is the very weapon we need to fight crime. Think of the use of Terahertz technology to discover the smuggling of drugs and explosives – the very same technology Qatar      has successfully employed. Or the infiltration of mobile phone crime rings by law enforcement operators via high tech, ethical hacking (as it was the case for the EncroChat operation). And even if crime has shown the capability to infiltrate any sector of society, such as sports, where money can be laundered over digital networks and matches can be rigged and coordinated via chats, technology can help spot the anomalies of money transfer, and data science can spot anomalies in matches, and can therefore thwart such a crime – a recent United Nations-sponsored event, participated by the International Centre for Sport Security (ICSS) Qatar and the College of Science and Engineering (CSE) at Hamad Bin Khalifa University (HBKU) discussed      the cited topic. In the end, the very same technology that is used by criminals is also used to fight crime itself.

Don’t get left behind

In the above-depicted cybersecurity cat-and-mouse game, the loser is the party that does not update its tools, does not plan, and does not evolve.

In particular, cybersecurity can help a country such as Qatar over two strategic dimensions: to better prevent/detect/react to the criminal usage of technology, as well as to advance robustly toward a knowledge-based economy and reinforce the country’s presence in the segment of high value-added services and products to fight crime.

In this context, a safe bet is to invest in education, for both governments and private citizens. On the one hand, only an educated workforce would be able to conceptualize/design/implement advanced cybersecurity tools and frameworks, as well as strategically frame the fight against crime. On the other hand, the same well-educated workforce will be able to spur innovation, create start-ups, produce novel high-skill products, and diversify the economy. 

In this context, Qatar enjoys a head start, thanks to its huge investment in education over the last 20 years. In particular, at HBKU – part of Qatar Foundation – where we have been educating future generations. 

CSE engages and leads in research disciplines of national and global importance. The college’s speciality divisions are firmly committed to excellence in graduate teaching and training of highly qualified students with entrepreneurial  capacity.

For instance, the MS in Cybersecurity offered by CSE touches on the foundations of cryptocurrencies, while the PhD in Computer Science and Engineering, offering several majors (including cybersecurity), prepares future high-level decision-makers, researchers, and entrepreneurs in the ICT domain  – the leaders who will be driving the digitalization of the economy and leading the techno-fight against crime.

Enhancing poverty measurement through big data

Published

on

Authors: Jasmina Ernst and Ruhimat Soerakoesoemah*

Ending poverty in all its forms is the first of the 17 Sustainable Development Goals (SDGs). While significant progress to reduce poverty had been made at the global and regional levels by 2019, the Covid-19 pandemic has partly reversed this trend. A significant share of the population in South-East Asia still lacks access to basic needs such as health services, proper nutrition and housing, causing many children to suffer from malnutrition and treatable illnesses. 

Delivering on the commitments of the 2030 Agenda for Sustainable Development and leaving no one behind requires monitoring of the SDG implementation trends. At the country level, national statistics offices (NSOs) are generally responsible for SDG data collection and reporting, using traditional data sources such as surveys, census and administrative data. However, as the availability of data for almost half of the SDG indicators (105 of 231) in South-East Asia is insufficient, NSOs are exploring alternative sources and methods, such as big data and machine learning, to address the data gaps. Currently, earth observation and mobile phone data receive most attention in the domain of poverty reporting. Both data sources can significantly reduce the cost of reporting, as the data collection is less time and resource intensive than for conventional data.

The NSOs of Thailand and the Philippines, with support from the Asian Development Bank, conducted a feasibility study on the use of earth observation data to predict poverty levels. In the study, an algorithm, convolutional neural nets, was pretrained on an ImageNet database to detect simple low-level features in images such as lines or curves. Following a transfer learning technique, the algorithm was then trained to predict the intensity of night lights from features in corresponding daytime satellite images. Afterwards income-based poverty levels were estimated using the same features that were found to predict night light intensity combined with nationwide survey data, register-based data, and geospatial information. The resulting machine learning models yielded an accuracy of up to 94 per cent in predicting the poverty categories of satellite images. Despite promising study results, scaling up the models and integrating big data and machine learning for poverty statistics and SDG reporting still face many challenges. Thus, NSOs need support to train their staff, gain continuous access to new datasets and expand their digital infrastructure.

Some support is available to NSOs for big data integration. The UN Committee of Experts on Big Data and Data Science for Official Statistics (UN-CEBD) oversees several task teams, including the UN Global Platform which has launched a cloud-service ecosystem to facilitate international collaboration with respect to big data. Two additional task teams focus on Big Data for the SDGs and Earth Observation data, providing technical guidance and trainings to NSOs. At the regional level, the weekly ESCAP Stats Café series provides a knowledge sharing platform for experiences related to the impact of COVID-19 on national statistical systems. The Stats Café includes multiple sessions dedicated to the use of alternative data sources for official statistics and the SDGs. Additionally, ESCAP has published policy briefs on the region’s practices in using non-traditional data sources for official statistics.

Mobile phone data can also be used to understand socioeconomic conditions in the absence of traditional statistics and to provide greater granularity and frequency for existing estimates. Call detail records coupled with airtime credit purchases, for instance, could be used to infer economic density, wealth or poverty levels, and to measure food consumption. An example can be found in poverty estimates for Vanuatu based on education, household characteristics and expenditure. These were generated by Pulse Lab Jakarta – a joint innovation facility associated with UN Global Pulse and the government of Indonesia.

Access to mobile phone data, however, remains a challenge. It requires long negotiations with mobile network operators, finding the most suitable data access model, ensuring data privacy and security, training the NSO staff and securing dedicated resources. The UN-CEBD – through the Task Team on Mobile Phone Data and ESCAP – supports NSOs in accessing and using mobile phone data through workshops, guides and the sharing of country experiences. BPS Statistics Indonesia, the Indonesian NSO, is exploring this data source for reporting on four SDG indicators and has been leading the regional efforts in South-East Asia. While several other NSOs in Asia and the Pacific can access mobile phone data or are negotiating access with mobile network operators, none of them have integrated it into poverty reporting.

As the interest and experience in the use of mobile phone data, satellite imagery and other alternative data sources for SDGs is growing among many South-East Asian NSOs, so is the need for training and capacity-building. Continuous knowledge exchange and collaboration is the best long-term strategy for NSOs and government agencies to track and alleviate poverty, and to measure the other 16 SDGs.
