  • [pib] Near-Surface Shear Layer (NSSL) of Sun

    Indian astronomers have found a theoretical explanation for the existence of the Near-Surface Shear Layer (NSSL) of the Sun for the first time.

    What is a Near-Surface Shear Layer?

    • It was long known the Sun’s equator spins faster than the poles.
    • However, a peek into the internal rotation of the Sun using sound waves revealed the existence of an intriguing layer where the rotation profile of the Sun changes sharply.
    • The layer is called as a near-surface shear layer (NSSL), and it exists very close to the solar surface, where there is an outward decrease in angular velocity.

    What have researchers found?

    • They have used an equation called the thermal wind balance equation to explain how the slight difference in temperature between solar poles and equator, called thermal wind term.
    • It is balanced by the centrifugal force appearing due to solar differential rotation.
    • They have noted that if this condition is true near the solar surface, it can explain the existence of NSSL, which is inferred in helioseismology (technique of using sound waves to peek inside the Sun) based observation.

    Why study NSSL?

    • Understanding NSSL is crucial for the study of several solar phenomena like sunspot formation, solar cycle, and it will also help in understanding such phenomena in other stars.
  • [pib] What are PRIDE Guidelines?

    The Union Ministry for Science & Technology has released “Biotech-PRIDE (Promotion of Research and Innovation through Data Exchange) Guidelines” developed by the Department of Biotechnology (DBT).

    Biotech-PRIDE

    • These guidelines aim at providing a well-defined framework and guiding principle to facilitate and enable sharing and exchange of biological knowledge, information and data.
    • They will facilitate this and enable the exchange of information to promote research and innovation in different research groups across the country.
    • They will be implemented through the Indian Biological Data Centre (IBDC) at Regional Centre for Biotechnology supported by the Department of Biotechnology.

    Creating a national repository: Bio-Grid

    • Other existing datasets/ data centres will be bridged to this IBDC which will be called Bio-Grid.
    • This Bio-Grid will be a National Repository for biological knowledge, information and data.
    • It will be responsible for enabling its exchange, developing measures for safety, standards and quality for datasets and establishing detailed modalities for accessing data.

     Why need such guidelines?

    • India ranks number 4 amongst the top 20 countries contributing biological databases.
    • The Government invests a large number of public funds for biosciences to gain deep insights into intricate biological mechanisms and other processes and for translation.
  • The epoch of cyberweapons

    Context

    The controversy over the use of Pegasus spyware for snooping highlights the threats posed by cyber-weapons.

    The emergence of the cyber weapons epoch

    • Cyberattacks on institutions such as banks and on critical infrastructure have proliferated to an alarming extent, signaling the emergence of the cyber weapon epoch.
    • Privacy has been eroded and the Internet has become a powerful weapon in the hands of those seeking to exploit its various facets.
    • Fifth dimension of warfare: Cyber is often touted as the fifth dimension of warfare — in addition to land, sea, air and space.

    The domain of everyday life

    • Cyber, as the domain of military and national security, also co-exists with cyber as a domain of everyday life.
    • The war is no longer out there.
    • It is now directly inside one’s drawing-room, with cyberweapons becoming the weapon of choice.
    • Israelis today dominate the cyber domain along with the Chinese, Russians, Koreans and, of course, the Americans.
    • The linkage between sabotage and intrusive surveillance is but a short step.

    Cyberattacks during the past decades

    •  Beginning with the 2007 devastating cyberattack on Estonia’s critical infrastructure, this was followed by the Stuxnet worm attack a few years later on Iran’s nuclear facility.
    • The Shamoon virus attack on Saudi Aramco occurred in 2012.
    • In 2016, a cyberattack occurred on Ukraine’s State power grid; in 2017 there was a Ransomware attack (NotPetya) which affected machines in as many as 64 countries.
    • United Kingdom’s National Health Service fell prey to the Wannacry attack the same year.
    • The series of attacks happened this year on Ireland’s Health Care System and in the United States such as ‘SolarWinds’, the cyber attack on Colonial Pipeline and JBS, etc.

    What are the threats posed by cyberattacks?

    • Cyberweapons carry untold capacity to distort systems and structures — civilian or military.
    • Cyberweapons also interfere with democratic processes, aggravate domestic divisions and, above all, unleash forces over which established institutions or even governments have little control.
    • As more and more devices are connected to networks, the cyber threat is only bound to intensify, both in the short and the medium term.
    • What is especially terrifying is that instruments of everyday use can be infected or infiltrated without any direct involvement of the target.
    • The possibilities for misuse are immense and involve far graver consequences to an individual, an establishment, or the nation.
    • It is not difficult to envisage that from wholesale espionage, this would become something far more sinister such as sabotage.

    Way forward

    • Deeper understanding:  Dealing with ‘zero day’ vulnerabilities require far more thought and introspection than merely creating special firewalls or special phones that are ‘detached’ from the Internet.
    • Recognising the mindset: What is needed is a deeper understanding of not only cyber technologies, but also recognising the mindsets of those who employ spyware of the Pegasus variety, and those at the helm of companies such as the NSO.
    • Short-term remedies are unlikely to achieve desired results.
    • No use of AI: Artificial Intelligence (AI) is often seen as a kind of panacea for many of the current problems and ills, but all advances in technology tend to be a double-edged sword.
    • If truth be told, AI could in turn make all information warfare — including cyber related — almost impossible to detect, deflect or prevent, at least at the current stage of development of AI tools.

    Conclusion

    All this suggests that security in the era of ever-expanding cyberweapons could become an ever-receding horizon.


    Back2Basics: Zero-day vulnerability

    • The term “zero-day” refers to a newly discovered software vulnerability.
    • Because the developer has just learned of the flaw, it also means an official patch or update to fix the issue hasn’t been released.
    • So, “zero-day” refers to the fact that the developers have “zero days” to fix the problem that has just been exposed — and perhaps already exploited by hackers.
  • Why cloudbursts could become more frequent?

    Recently, cloudbursts have been reported from several places in J&K, Ladakh, Uttarakhand and Himachal Pradesh. A

    What is a Cloudburst?

    • Cloudbursts are short-duration, intense rainfall events over a small area.
    • According to the IMD, it is a weather phenomenon with unexpected precipitation exceeding 100mm/h over a geographical region of approximately 20-30 square km.

    What causes Cloudburst?

    • A study published last year studied the meteorological factors behind the cloudburst over the Kedarnath region.
    • They analyzed atmospheric pressure, temperature, rainfall, cloud water content, cloud fraction, cloud particle radius, cloud mixing ratio, total cloud cover, wind speed, wind direction, and relative humidity during the cloudburst, before as well as after the cloudburst.
    • The results showed that during the cloudburst, the relative humidity and cloud cover was at the maximum level with low temperature and slow winds.
    • It is expected that because of this situation a high amount of clouds may get condensed at a very rapid rate and result in a cloudburst.

    Impact of climate change

    • Several studies have shown that climate change will increase the frequency and intensity of cloudbursts in many cities across the globe.
    • As temperatures increase the atmosphere can hold more and more moisture and this moisture comes down as a short very intense rainfall for a short duration.
    • This results in flash floods in the mountainous areas and urban floods in the cities.
    • Also, there is evidence suggesting that globally short duration rainfall extremes are going to become more intense and frequent.

  • [pib] 14 Indian Tiger Reserves get Global CA/TS recognition

    The Environment Ministry has released the names of the 14 tiger reserves that had received the accreditation of the Global Conservation Assured|Tiger Standards (CA|TS), an accreditation tool agreed upon by tiger range countries.

    Conservation Assured | Tiger Standards (CA|TS)

    • CA|TS has been agreed upon as an accreditation tool by the global coalition of Tiger Range Countries (TRCs) and has been developed by tiger and protected area experts.
    • Officially launched in 2013, it sets minimum standards for effective management of target species and encourages the assessment of these standards in relevant conservation areas.
    • CA|TS is a set of criteria that allows tiger sites to check if their management will lead to successful tiger conservation.
    • The Global Tiger Forum (GTF), an international NGO working on tiger conservation, and World Wildlife Fund India are the two implementing partners of the National Tiger Conservation Authority for CATS assessment in India.

    Which are the 14 reserves?

    The 14 tiger reserves which have been accredited are:

    • Manas, Kaziranga and Orang in Assam,
    • Satpura, Kanha and Panna in Madhya Pradesh,
    • Pench in Maharashtra,

  • How to exit farming risk trap

    Context

    The farmers’ protest against farm laws brings into focus the factors afflicting agriculture in India.

    Issues of Indian agriculture

    • Some 50 years after the Green Revolution, an all-India agricultural landscape is characterized by relatively low productivity levels that co-exist with high levels of variation in crop yields across our farming districts.
    • Excessive control: Various government agencies have a say on all aspects of the farmer’s livelihood — the latest count includes 13 central and countless state ministries and agencies.
    • These agencies oversee rural property rights, land use, and land ceilings; commodity prices, input subsidies, and taxes, infrastructure, production, credit, marketing and procurement, public distribution, research, education, trade policy, etc.
    • Poor policies: The result has been a mix of arbitrary and conflicting policy interventions by both the central and state government agencies.
    • Poor provision of basic public goods: This, combined with poor and varying levels of provision of basic public goods, including irrigation explains the poor state of Indian agriculture.

    Risk-to-return in agriculture

    • The following figures indicate the median (typical) district-level yield (in tonnes-per-hectare) for four major crops — rice, wheat, maize, and cotton — along with the geographic variability of this yield (risk) across all reporting districts for each year from 1966 to 2018.
    • Combining these two values — median district yield and its geographic variability across all farming districts — provides us a measure of the all-India level of risk-to-return, in percentage terms.

    Lessons from risk-to-return profile

    • One, the large gap in rice and wheat yields that opened up between Punjab and Haryana and the farm districts in the rest of the country remains far from being closed.
    • Limited mobility of ideas: There is severe unevenness in the provision of common goods across districts — irrigation, roads, power, etc.
    • There is also the absence of well-functioning markets for agricultural land, crops, and inputs, the slow labour reform, and the poor quality of education.
    • These two factors have worked to reduce overall resource mobility within and across our farming districts.
    • Most importantly, they have limited the mobility of ideas and technology needed to increase productivity and reduce the variation of yield across districts.
    • Decentralization failed: As a result of lack of mobility, the real promise of a decentralized system — of experimentation, of learning from each other, and the adoption of best practices and policies — has failed to materialize.
    • Distortion due to subsidies: Various input subsidies and minimum price guarantee procurement schemes provided by the state have worked to worsen the overall levels of productivity and the risk in agriculture, generating adverse effects for all of us, through the degradation of our water resources, soil, health, and climate.
    • At the same time, these policies have tightened the trap our farm households find themselves in.
    • Thus, as is evident in the next chart, outside of rice and wheat, the risk-to-return levels are even higher in the case of maize and cotton, including for Punjab.
    • As a result, the farm households of Punjab and Haryana fear both, the loss of state support for rice and wheat and the higher risks implied by a switch to other crops.

    Way forward

    • Minimize risk: The guiding principle for three farm laws must be to create conditions that allow farm households to maximize their income while minimizing the overall level of risk in Indian agriculture.
    • Freedom of choice: Farmers must be made free to determine the best mix of resources, land, inputs, technology, and organizational forms for their farms.
    • More freedom: Farmers, just as entrepreneurs in the non-farm sector, must be allowed to enter and exit agriculture, on their own terms and contract with whomever they wish.
    • Allow entry of corporates: Entry of the large or small private corporates in the Indian agricultural stream will help the Indian farmer, along with the rest of us, move to a low-risk, high-return path of progress.

    Conclusion

    The more we delay the needed reforms, the more difficult it will prove to be for all of us to extract ourselves out of these risk-laden currents of agriculture.

  • What is National Farmers Database?

    The Centre’s new National Farmers Database will only include land-owning farmers for now as it will be linked to digitized land records.

    National Farmers Database

    • The Central government had proposed an Agristack initiative to create a digital database that focuses on farmers and the agricultural sector.
    • As part of the first step of this initiative, the government has initiated a farmers database that would serve as the core of the Agristack.
    • The database would be linked to the digital land record management system and would thus only include farmers who were legal owners of agricultural land.
    • The database would facilitate online single sign-on facilities for universal access and usher in proactive and personalized services to farmers such as DBT, soil and plant health advisories, weather advisories
    • It would also facilitate seamless credit & insurance, seeds, fertilizers, and pesticide-related information.

    Need for such database

    • India has 140 million operational farmland holdings.
    • The availability of a database would serve an important role in the formulation of evidence-based policies for the agricultural sector.
    • Also, the government can make use of the database for targeted service delivery with higher efficiency and in a focused and time-bound manner.
    • The database could be used to select beneficiaries of government schemes.
    • The availability of data will make it possible to implement digital technologies like AI/Machine Learning, IoT in the agricultural domain, thus opening up the sector to immense opportunities for improvement in productivity.

    Back2Basics: AgriStack Initiative

    • The AgriStack is a collection of technologies and digital databases proposed by the Central Government focusing on India’s farmers and the agricultural sector.
    • The central government has claimed that these new databases are being built to primarily tackle issues such as poor access to credit and wastage in the agricultural supply chain.
    • Under AgriStack’, the government aims to provide ‘required data sets’ of farmers’ personal information to Microsoft to develop a farmer interface for ‘smart and well-organized agriculture’.
    • The digital repository will aid the precise targeting of subsidies, services, and policies.
    • Under the program, each farmer of the country will get what is being called an FID, or a farmers’ ID, linked to land records to uniquely identify them.
  • Telangana’s Dalit Bandhu Scheme

    Telangana CM has recently been informed to spend Rs 80,000 crore to Rs 1 lakh crore for Dalit Bandhu Scheme, touted as the country’s biggest direct benefit transfer scheme, to empower Dalits across the state.

    Dalit Bandhu Scheme

    • Dalit Bandhu is the latest flagship program of the Telangana government.
    • It is envisioned as a welfare scheme for empowering Dalit families and enable entrepreneurship among them through a direct benefit transfer of Rs 10 lakh per family.
    • This is, once implemented on the ground, going to be the biggest cash transfer scheme in the country.
    • Apart from monetary assistance, the government plans to create a corpus called the Dalit Security Fund permanently to support the beneficiary in the event of any adversities.
    • This fund will be managed by the district collector concerned, along with a committee of beneficiaries.
    • The beneficiary would be issued an identity card with an electronic chip, which will help the government monitor the progress of the scheme.

    Where is the scheme being implemented?

    • The CM decided to implement it on a pilot basis in the Huzurabad Assembly constituency.
    • Based on the experiences of implementation in Huzurabad, the scheme will be rolled out across the state in a phased manner.
    • Officials were asked to visit Dalit colonies and interact with Dalit families to find out their views and opinions before preparing guidelines for the scheme.
    • The pilot project will focus on monitoring the implementation of the scheme, evaluating the results, and also creating a safety fund for the beneficiaries with the government’s participation.

    How is Dalitha Bandhu being implemented?

    • The CM has ensured that the Dalit Bandhu is free.
    • The governments in the past came out with some schemes and asked for bank guarantees.
    • This is not a loan. There is no need to repay it. There is no chance of any involvement of middlemen.
    • To promote Dalit entrepreneurship, the government has decided to start a system of reservations for Dalits in sectors where the government issues licenses.
    • The government will provide reservations for Dalits in issuing licenses for wine shops, medical shops, fertilizer shops, rice mills, etc.
