A diverse range of breakthrough technologies, including “artificial leaves” that turn CO2 into fuel, and a technique that harvests water from air, could soon be playing a role in tackling the world’s most pressing challenges.

The top 10 technologies to make this year’s list are:-

1. Liquid biopsies

Liquid biopsies mark a step forward in the fight against cancer. First, they are an alternative where traditional tissue-based biopsies are not possible. Second, they provide a full spectrum of information compared to tissue samples, which only reflect the information available in the sample. Lastly, by homing in on circulating-tumor DNA (ctDNA), genetic material that routinely finds its way from cancer cells into the bloodstream, disease progression or resistance to treatment can be spotted much faster than otherwise relying on symptoms or imaging.

2. Harvesting clean water from air

The ability to extract clean water from air is not new, however existing techniques require high moisture levels and a lot of electricity. This is changing. A team from MIT and University of California, Berkeley has successfully tested a process using porous crystals that convert the water using no energy at all. Another approach, by a start-up called Zero Mass Water from Arizona is able to produce 2-5 litres of water a day based on an off-grid solar system.

3. Deep learning for visual tasks

Computers are beginning to recognize images better than humans. Thanks to deep learning, an emerging field of artificial intelligence, computer-vision technologies are increasingly being used in applications as diverse as driving autonomous vehicles, medical diagnostics, damage assessment for insurance claims and monitoring of water levels and crop yield.

4. Liquid fuels from sunshine

Can we mimic the humble leaf to create an artificial photosynthesis to generate and store energy? The prospects are looking increasingly positive. The answer lies in using sunlight-activated catalysts to split water molecules into water and hydrogen, and then using the same hydrogen to convert CO2 into hydrocarbons. Such a closed system – wherein CO2 emitted by combustion is then transformed back into fuel instead of the atmosphere – could prove to be revolutionary for the solar and wind industries.

5. The Human Cell Atlas

An international collaboration aimed at deciphering the human body, called the Human Cell Atlas, was launched in October 2016. The project, backed by the Chan Zuckerberg Initiative aims to identify every cell type in every tissue; learn exactly which genes, proteins and other molecules are active in each type and the processes which control that activity; determine where the cells are located exactly; how the cells normally interact with one another, and what happens to the body’s functioning when genetic or other aspects of a cell undergo change, among other things. The end product will be an invaluable tool for improving and personalizing health care.

6. Precision farming

The Fourth Industrial Revolution is providing farmers with a new set of tools to boost crop yield and quality while reducing water and chemical use. Sensors, robots, GPS, mapping tools and data-analytics software are all being used to customize the care that plants need. While the prospect of using drones to capture plant health in real time may be some way off for most of the world’s farmers, low-tech techniques are coming online too. Salah Sukkarieh, of the University of Sydney, for instance, has demonstrated a streamlined, low-cost monitoring system in Indonesia that relies on solar power and cell phones.

7. Affordable catalysts for green vehicles

Progress is being made on a promising zero-emission technology, the hydrogen-fed fuel cell. Progress to date has been stymied by the high price of catalysts which contain platinum. However, much progress has been made reducing reliance on this rare and expensive metal, and the latest developments involve catalysts that include no platinum, or in some cases no metal at all.

8. Genomic vaccines

Vaccines based on genes are superior to more conventional ones in a number of ways. They are faster to manufacture for one thing, which is crucial at times of a violent outbreak. Compared to manufacturing proteins in cell culturesor eggs, producing genetic material should also be simpler and less expensive. A genomics-based approach to vaccines also enables more rapid adaptation in the event of a pathogen mutating, and finally allows scientists to identify people who are resistant to a pathogen, isolate the antibodies that provide that protection, and design a gene sequence that will induce a person’s cells to produce those antibodies.

9. Sustainable design of communities

Applying green construction to multiple buildings at once has the potential to revolutionize the amount of energy and water we consume. Sending locally-generated solar power to a smart microgrid could reduce electricity consumption by half and reduce carbon emissions to zero if a project currently under development at the University of California at Berkeley Goes to plan. Meanwhile, the same project’s plan to re-design water systems so that waste water from toilets and drains is treated and re-used on site, with rainwater diverted to toilets and washers, could cut demand for potable water by 70%.

10. Quantum computing

Quantum computers’ almost limitless potential has only ever been matched by the difficulty and cost of their construction. Which explains why today the small ones that have been built have not yet managed to exceed the power of supercomputers. But progress is being made and in 2016 the technology firm IBM provided the public access to the first quantum computer in the cloud. This has already led to more than 20 academic papers being published using the tool and today more than 50 start-ups and large corporations worldwide are focused on making quantum computing a reality. With such progress behind us, the word on people’s lips now is “Quantum Ready.”

  • In a diverse country like India, where each State is socially, culturally, economically, and politically distinct, measuring Governance becomes increasingly tricky. The Public Affairs Index (PAI 2021) is a scientifically rigorous, data-based framework that measures the quality of governance at the Sub-national level and ranks the States and Union Territories (UTs) of India on a Composite Index (CI).


    States are classified into two categories – Large and Small – using population as the criteria.

    In PAI 2021, PAC defined three significant pillars that embody GovernanceGrowth, Equity, and Sustainability. Each of the three Pillars is circumscribed by five governance praxis Themes.

    The themes include – Voice and Accountability, Government Effectiveness, Rule of Law, Regulatory Quality and Control of Corruption.

    At the bottom of the pyramid, 43 component indicators are mapped to 14 Sustainable Development Goals (SDGs) that are relevant to the States and UTs.

    This forms the foundation of the conceptual framework of PAI 2021. The choice of the 43 indicators that go into the calculation of the CI were dictated by the objective of uncovering the complexity and multidimensional character of development governance

    The Equity Principle

    The Equity Pillar of the PAI 2021 Index analyses the inclusiveness impact at the Sub-national level in the country; inclusiveness in terms of the welfare of a society that depends primarily on establishing that all people feel that they have a say in the governance and are not excluded from the mainstream policy framework.

    This requires all individuals and communities, but particularly the most vulnerable, to have an opportunity to improve or maintain their wellbeing. This chapter of PAI 2021 reflects the performance of States and UTs during the pandemic and questions the governance infrastructure in the country, analysing the effectiveness of schemes and the general livelihood of the people in terms of Equity.

    Growth and its Discontents

    Growth in its multidimensional form encompasses the essence of access to and the availability and optimal utilisation of resources. By resources, PAI 2021 refer to human resources, infrastructure and the budgetary allocations. Capacity building of an economy cannot take place if all the key players of growth do not drive development. The multiplier effects of better health care, improved educational outcomes, increased capital accumulation and lower unemployment levels contribute magnificently in the growth and development of the States.

    The Pursuit Of Sustainability

    The Sustainability Pillar analyses the access to and usage of resources that has an impact on environment, economy and humankind. The Pillar subsumes two themes and uses seven indicators to measure the effectiveness of government efforts with regards to Sustainability.

     

    The Curious Case Of The Delta

    The Delta Analysis presents the results on the State performance on year-on-year improvement. The rankings are measured as the Delta value over the last five to 10 years of data available for 12 Key Development Indicators (KDI). In PAI 2021, 12 indicators across the three Pillars of Equity (five indicators), Growth (five indicators) and Sustainability (two indicators). These KDIs are the outcome indicators crucial to assess Human Development. The Performance in the Delta Analysis is then compared to the Overall PAI 2021 Index.

    Key Findings:-

    1. In the Large States category (overall), Chhattisgarh ranks 1st, followed by Odisha and Telangana, whereas, towards the bottom are Maharashtra at 16th, Assam at 17th and Gujarat at 18th. Gujarat is one State that has seen startling performance ranking 5th in the PAI 2021 Index outperforming traditionally good performing States like Andhra Pradesh and Karnataka, but ranks last in terms of Delta
    2. In the Small States category (overall), Nagaland tops, followed by Mizoram and Tripura. Towards the tail end of the overall Delta ranking is Uttarakhand (9th), Arunachal Pradesh (10th) and Meghalaya (11th). Nagaland despite being a poor performer in the PAI 2021 Index has come out to be the top performer in Delta, similarly, Mizoram’s performance in Delta is also reflected in it’s ranking in the PAI 2021 Index
    3. In terms of Equity, in the Large States category, Chhattisgarh has the best Delta rate on Equity indicators, this is also reflected in the performance of Chhattisgarh in the Equity Pillar where it ranks 4th. Following Chhattisgarh is Odisha ranking 2nd in Delta-Equity ranking, but ranks 17th in the Equity Pillar of PAI 2021. Telangana ranks 3rd in Delta-Equity ranking even though it is not a top performer in this Pillar in the overall PAI 2021 Index. Jharkhand (16th), Uttar Pradesh (17th) and Assam (18th) rank at the bottom with Uttar Pradesh’s performance in line with the PAI 2021 Index
    4. Odisha and Nagaland have shown the best year-on-year improvement under 12 Key Development indicators.

    In the Scheme of Things

    The Scheme Analysis adds an additional dimension to ranking of the States on their governance. It attempts to complement the Governance Model by trying to understand the developmental activities undertaken by State Governments in the form of schemes. It also tries to understand whether better performance of States in schemes reflect in better governance.

    The Centrally Sponsored schemes that were analysed are National Health Mission (NHM), Umbrella Integrated Child Development Services scheme (ICDS), Mahatma Gandh National Rural Employment Guarantee Scheme (MGNREGS), Samagra Shiksha Abhiyan (SmSA) and MidDay Meal Scheme (MDMS).
