  • PM -WANI : As Game changer

    The PM-WANI project seems to fit within the framework of an evolving decentralized concept to bridge the e-divide.

    Practice Question:

    With the PM-WANI, the state is expanding the reach of digital transformation to those who have been excluded till now. It is a game-changer because it has the potential to move Digital India to Digital Bharat. Discuss.

    PM WANI – the ‘game-changer’

    • The term ‘game-changer’ can be seen as an accurate reflection of the capability of an initiative to change the status quo for Prime Minister’s Wi-Fi Access Network Interface, or PM WANI.
    • It provides for “Public Wi-Fi Networks by Public Data Office Aggregators (PDOAs) to provide public Wi-Fi service spread across the length and breadth of the country to accelerate the proliferation of Broadband Internet services through Public Wi-Fi network in the country”.

    What the data shows

    • The initiative can help to bridge the increasing digital divide in India. Recently, the NITI Aayog CEO had said that India can create $1 trillion of economic value using digital technology by 2025.
    • As per the latest Telecom Regulatory Authority of India (TRAI) data, about 54% of India’s population has access to the Internet.
    • The 75th round of the National Statistical Organization survey shows that only 20% of the population has the ability to use the Internet.
    • The India Internet 2019 report shows that rural India has half the Internet penetration as urban, and twice as many users who access the Internet less than once a week.

    Digital poverty

    • Umang App (Unified Mobile Application for New-age Governance) allows access to 2,084 services, across 194 government departments, across themes such as education, health, finance, social security, etc.
    • The ability to access and utilize the app enhances an individual’s capabilities to benefit from services that they are entitled to.
    • With each move towards digitization, we are threatening to leave behind a large part of our population to suffer in digital poverty.
    • What the government is trying to achieve with PM-WANI is anyone living in their house, a paan shop owner or a tea seller can all provide public Wi-Fi hot posts, and anyone within range can access it.
    • This will also help to reduce the pressure on the mobile Internet in India. Going back to the India Internet report, it shows that 99% of all users in India access the Internet on mobile, and about 88% are connected on the 4G network.
    • This leads to a situation where everyone is connected to a limited network, which is getting overloaded and resulting in bad speed and quality of Internet access.

    Key links

    • There are three important actors here.
    1. First is the Public Data Office (PDO). The PDO can be anyone, and it is clear that along with Internet infrastructure, the government also sees this as a way to generate revenue for individuals and small shopkeepers. It is important to note that PDOs will not require registration of any kind, thus easing the regulatory burden on them.
    2. Second is the PDOA, who is basically the aggregator who will buy bandwidth from the Internet service provider (ISPs) and telecom companies and sell it to PDOs, while also accounting for data used by all PDOs.
    3. The third is the app provider, who will create an app through which users can access and discover the Wi-Fi access points.
    • Two pillars have been given as a baseline for public Wi-Fi.
    1. Interoperability – where the user will be required to login only once and stay connected across access points.
    2. Multiple payment options – allowing the user to pay both online and offline.
    • The products should start from low denominations, starting with ₹2. It is suggested in the report that the requirement of authentication through stored e-know your customer (KYC) is encouraged, which inevitably means a linking with Aadhaar.

    Aiding rural connectivity

    • The PM-WANI has the potential to change the fortunes of Bharat Net as well. Bharat Net envisions broadband connectivity in all villages in India.
    • The project has missed multiple deadlines, and even where the infrastructure has been created, usage data is not enough to incentivize ISPs to use Bharat Net infra to provide services.
    • One of the reasons for the lack of demand is the deficit in digital literacy in India and the lack of last-mile availability of the Internet.
    • The term digital literacy must be seen as an evolving decentralized concept, which depends on how people interact with technology in other aspects of their life and is influenced by local social and cultural factors.
    • The PM-WANI seems to fit within this framework, simply because it seeks to make accessing the Internet as easy as having tea at a chai shop. This is not a substitute for the abysmal digital literacy efforts of the government, but will definitely help.

    Security, privacy issues

    • There are some concerns, mainly with respect to security and privacy. A large-scale study conducted at public Wi-Fi spots in 15 airports across the United States, Germany, Australia, and India discovered that two thirds of users leak private information whilst accessing the Internet.
    • Further, the TRAI report recommends that ‘community interest’ data be stored locally, raising questions about data protection in a scenario where the country currently does not have a data protection law in place.
    • These are, however, problems of regulation, state capacity and awareness and do not directly affect the framework for this scheme.

  • [pib] Vision 2035: Public Health Surveillance in India

    NITI Aayog today released a white paper: Vision 2035: Public Health Surveillance (PHS) in India.

    Q.Discuss the role of Public Health Surveillance in the success of Ayushman Bharat Abhiyan.

    Vision 2035 for PHS

    • It is a continuation of the work on health systems strengthening.
    • It contributes by suggesting mainstreaming of surveillance by making individual electronic health records the basis for surveillance.
    • Public health surveillance (PHS) is an important function that cuts across primary, secondary, and tertiary levels of care. Surveillance is ‘Information for Action’.

    Let’s have a look at the executive summary of the vision document:

    PHS in India

    • Surveillance is an important Public Health function.
    • It is an essential action for disease detection, prevention, and control. Surveillance is ‘Information for Action’.

    Why need PHS?

    • Multiple disease outbreaks have prompted India to proactively respond with prevention and control measures. These actions are based on information from public health surveillance.
    • India was able to achieve many successes in the past. Smallpox was eradicated and polio was eliminated.
    • India has been able to reduce HIV incidence and deaths and advance and accelerate TB elimination efforts.
    • These successes are a result of effective community-based, facility-based, and health system-based surveillance.
    • The COVID19 pandemic has further challenged the country. India rapidly ramped up its diagnostic capabilities and aligned its digital technology expertise.
    • This ensured that there was a comprehensive tracking of the pandemic.

    Highlights of the vision document

    • It builds on initiatives such as the Integrated Health Information Platform of the Integrated Disease Surveillance Program.
    • It aligns with the citizen-centricity highlighted in the National Health Policy 2017 and the National Digital Health Blueprint.
    • It encourages the use of mobile and digital platforms and point of care devices and diagnostics for amalgamation of data capture and analyses.
    • It highlights the importance of capitalizing on initiatives such as the Clinical Establishments Act to enhance private sector involvement in surveillance.
    • It points out the importance of a cohesive and coordinated effort of apex institutions including the National Centre for Disease Control, the ICMR, and others.

    Gap areas in India’s PHS that could be addressed

    • India can create a skilled and strong health workforce dedicated to surveillance activities.
    • Non-communicable disease, reproductive and child health, occupational and environmental health and injury could be integrated into public health surveillance.
    • Morbidity data from health information systems could be merged with mortality data from vital statistics registration.
    • An amalgamation of plant, animal, and environmental surveillance in a One-Health approach.
    • PHS could be integrated within India’s three-tiered health system.
    • Citizen-centric and community-based surveillance, and use of point of care devices and self-care diagnostics could be enhanced.
    • To establish linkages across the three-tiered health system, referral networks could be expanded for diagnoses and care.

    Moving ahead

    • Establish a governance framework that is inclusive of political, policy, technical, and managerial leadership at the national and state level.
    • Identify broad disease categories that will be included under PHS.
    • Enhance surveillance of non-communicable diseases and conditions in a step-wise manner.
    • Prioritize diseases that can be targeted for elimination as a public health problem, regularly.
    • Improve core support functions, core functions, and system attributes for surveillance at all levels; national, state, district, and block.
    • Establish mechanisms to streamline data sharing, capture, analysis, and dissemination for action.
    • Encourage innovations at every step-in surveillance activity.

  • Delimitation should be based on 2031 Census

    A paper released by the Pranab Mukherjee Foundation (PMF) has suggested that the next delimitation exercise should be a two-step process:

    1. First a Delimitation Commission should be set up to redraw boundaries of constituencies on the basis of the 2031 Census
    2. And then a State Reorganization Act be passed to split States into smaller ones

    Q.With the new Parliament House, the role of the Presiding officers of the Houses is going to be more challenging. Discuss, how.

    Back in news

    • PM recently inaugurated a brand new Parliament Annexe building that will afford our lawmakers more space and enable better functioning.
    • In a few years from now, we might actually need a new building for Parliament altogether due to the likely increase in a number of seats in both Houses after the lifting of the freeze imposed by the 42nd Constitutional Amendment Act, 1976, which is due in 2026.

    What is Delimitation? Why is it needed?

    • Delimitation is the act of redrawing boundaries of Lok Sabha and state Assembly seats to represent changes in population.
    • In this process, the number of seats allocated to different states in Lok Sabha and the total number seats in a Legislative Assembly may also change.
    • The main objective of delimitation is to provide equal representation to equal segments of a population.
    • It also aims at a fair division of geographical areas so that one political party doesn’t have an advantage over others in an election.

    Why such debate?

    • The 84th Amendment to the Constitution in 2002 had put a freeze on the delimitation of Lok Sabha and State Assembly constituencies till the first Census after 2026.
    • While the current boundaries were drawn on the basis of the 2001 Census, the number of Lok Sabha seats and State Assembly seats remained frozen on the basis of the 1971 Census.
    • The population according to the last census preceding the freeze was 50 crore, which in 50 years has grown to 130 crores.
    • This has caused a massive asymmetry in the political representation in the country.

    Why there are fewer delimitations?

    • The Constitution mandates that the number of Lok Sabha seats allotted to a state would be such that the ratio between that number and the population of the state is, as far as practicable, the same for all states.
    • Although unintended, this provision implied that states that took little interest in population control could end up with a greater number of seats in Parliament.
    • The southern states that promoted family planning faced the possibility of having their seats reduced.
    • To allay these fears, the Constitution was amended during Indira Gandhi’s Emergency rule in 1976 to suspend delimitation until 2001.
    • Despite the embargo, there were a few occasions that called for readjustment in the number of Parliament and Assembly seats allocated to a state.

    Background

    • According to Article 81 of the Constitution — as it stood before the 42nd CAA 1976 — the Lok Sabha was to comprise of not more than 550 members.
    • Clause (2) of Article 81 provided that there shall be allotted to each State a number of MPs in such manner that the ratio between that number and the population of the State is the same for all States.
    • Further, clause (3) defined the expression “population” for the purposes of Article 81 to mean the population as ascertained at the last preceding census of which the relevant figures have been published.

    Dilemma over delimitation

    • States which took a lead in population control faced the prospect of their number of seats getting reduced and States which had higher population figures stood to gain by increase in the number of seats in Lok Sabha.
    • As a result of the freezing of the allocation of seats, the allocation done on the basis of the 1971 Census continues to hold good for the present population figures.
    • According to the 2011 Census, the population of our country stands at 121 crores with a registered electorate of 83.41 crores.
    • Basing the 1971 Census figure of 54.81 crores to represent today’s population presents a distorted version of our democratic polity and is contrary to what is mandated under Article 81 of the Constitution.
    • So when the first Census figure will be available after 2026 — that is, in 2031 — a fresh delimitation will have to do which will dramatically alter the present arrangement of seat allocation to the States in Parliament.

    Acquainting more MPs: A big challenge

    • One question that has to be addressed is how the Presiding Officers of the Houses/Legislatures will deal with such a large number of members to capture the attention of the Speaker to raise issues in the House.
    • Even with the current strength of 543 members, the Speaker finds it extremely difficult to conduct the proceedings of the House.
    • Members do not show much heed to the appeals of the Speaker, thereby making smooth conduct of House proceedings a difficult affair.
    • The Speaker’s directions and rulings are not shown proper respect, and disruptions of proceedings aggravate the problem.
    • The sudden increase in numbers will render the task of the Speaker more difficult and onerous.

    Conclusion

    • While 2026 is still a few years away. But we need to be clear on how to deal with the problems that are likely to arise, we will be forced to postpone the lifting of the freeze to a future date as was done in 2001.
    • This will only postpone the problem for which we must find a solution sooner or later.
    • Even the various proposals for electoral reforms which have been recommended by various Commissions over the past decade do not address these issues.
    • These are challenges which our political leaders have to address in the immediate future.

  • National Family Health Survey- 5 Part: I

    • Current times require integrated and coordinated efforts from all health institutions, academia and other partners directly or indirectly associated with the health care services to make these services accessible, affordable and acceptable to all.
    • The data in NFHS-5 gives requisite input for strengthening existing programmes and evolving new strategies for policy intervention, therefore government and authorities should take steps to further improve the condition of women in India.

    The first phase of the fifth National Family Health Survey (NFHS-5) has been released.

    Do you think that India is still the sick man of Asia?

    What is the National Family Health Survey?

    • The NFHS is a large-scale, multi-round survey conducted in a representative sample of households throughout India.
    • Three rounds of the survey have been conducted since the first survey in 1992-93.
    • The survey provides state and national information for India on fertility, infant and child mortality, the practice of family planning, maternal and child health, reproductive health, nutrition, etc.
    • The Ministry of Health has designated the International Institute for Population Sciences (IIPS) Mumbai, as the nodal agency, responsible for providing coordination and technical guidance for the survey.

    Part I of the Survey

    • The latest data pertains to 17 states — including Maharashtra, Bihar, and West Bengal — and five UTs (including J&K) and, crucially, captures the state of health in these states before the Covid pandemic.
    • Phase 2 of the survey, which will cover other states such as Uttar Pradesh, Punjab and Madhya Pradesh, was delayed due to the pandemic and its results are expected to be made available in May 2021.

    Highlights of the NHFS-5

    • The NFHS-5 contains detailed information on population, health, and nutrition for India and its States and Union Territories.
    • This is a globally important data source as it is comparable to Demographic Health Surveys (DHS) Programme of 90 other countries on several key indicators.
    • It can be used for cross country comparisons and development indices.

    Good news

    • Several of the 22 states and UTs, for which findings have been released, showed an increase in childhood immunisation.
    • There has been a drop in neonatal mortality in 15 states, a decline in infant mortality rates in 18 states and an increase in the female population (per 1,000 males) in 17 states.
    • Fertility rate decline and increase in contraceptive use were registered in almost all the states surveyed showing trends of population stabilization.

    Some bad news

    • There has been an increase in stunting and wasting among children in several states, a rise in obesity in women and children, and an increase in spousal violence.
    • In several other development indicators, the needle has hardly moved since the last NFHS-4.

    (1) Hunger Alarm

    • The proportion of stunted children has risen in several of the 17 states and five UTs surveyed, putting India at risk of reversing previous gains in child nutrition made over previous decades.
    • Worryingly, that includes richer states like Kerala, Gujarat, Maharashtra, Goa and Himachal Pradesh.
    • The share of underweight and wasted children has also gone up in the majority of the states.

    (2) Fertility Rate

    The total fertility rate (TFR) is defined as the average number of children that would be born to a woman by the time she ends childbearing.

    • The TFR across most Indian states declined in the past half-a-decade, more so among urban women, according to the latest NFHS-5.
    • Sikkim recorded the lowest TFR, with one woman bearing 1.1 children on average; Bihar recorded the highest TFR of three children per woman.
    • In 19 of the 22 surveyed states, TFRs were found to be ‘below-replacement’ — a woman bore less than two children on average through her reproductive life.
    • India’s population is stabilizing, as the total fertility rate (TFR) has decreased across majority of the states.

    (3) Under-5 and infant mortality rate (IMR)

    • The Under 5 and infant mortality rate (IMR) has come down but in parallel recorded an increase in underweight and severely wasted under 5 children among 22 states that were surveyed.
    • These states are Goa, Gujarat, Himachal Pradesh, Kerala, Maharashtra, Meghalaya, Mizoram, Nagaland, Telangana, Tripura, West Bengal, Lakshadweep and Dadra & Nagar Haveli and Daman and Diu.

    For the first time: Gaps in internet use

    • In 2019, for the first time, the NFHS-5, which collects data on key indicators on population health, family planning and nutrition, sought details on two specific indicators: Percentage of women and men who have ever used the Internet.
    • On average, less than 3 out of 10 women in rural India and 4 out of 10 women in urban India ever used the Internet, according to the survey.
    1. First, only an average of 42.6 per cent of women ever used the Internet as against an average of 62.16 per cent among the men.
    2. Second, in urban India, average 56.81 per cent women ever used the Internet compared to an average of 73.76 per cent among the men.
    3. Third, dismal 33.94 per cent women in rural India ever used the Internet as against 55.6 per cent among men.
    • In urban India, 10 states and three union territories reported more than 50 per cent women who had ever used the Internet: Goa (78.1%), Himachal Pradesh (78.9%), Kerala (64.9%), and Maharashtra (54.3%).
    • The five states reporting the lowest percentage of women, whoever used the Internet in urban India were Andhra Pradesh (33.9%), Bihar (38.4%), Tripura (36.6%), Telangana (43.9%) and Gujarat (48.9%).

  • What is Project 17A?

    Himgiri, the first of the three stealth frigates being built by Garden Reach Shipbuilders and Engineers (GRSE), Kolkata, under Project 17A for the Navy, was launched into the water.

    Try this question:

    Q“To be secure on Land, we must be Supreme at Sea”. In this context, discuss why India is primarily a Maritime Nation?

    Project 17A

    • The coveted ‘Project 17A’ was cleared by the govt back in 2015.
    • It involves the building of seven stealth frigates at an estimated cost of Rs 50,000 crore.
    • Of these seven, the contract for three frigates was awarded to GRSE while the contract for another four frigates was awarded to Government-owned Mazagon Docks Limited (MDL) which is based in Mumbai.
    • These frigates will come armed with advanced state-of-the-art sensors and boast of top-notch stealth features.
    • They will represent the most advanced class of major surface warships for the Indian Navy in a decade, also featuring BrahMos supersonic surface-to-surface missiles.
    • These will also have torpedoes and rockets to hit submarines and rapid-fire guns to destroy anti-ship missiles as well as a heavy main gun to engage ships and coastal target.

  • Species in news: Himalayan Serow

    A Himalayan Serow has been sighted for the first time in the Himalayan cold desert region.

    Try this MCQ:

    Q.In which one of the following State, the Rupi Bhaba Wildlife Sanctuary is located?

    (a) Himachal Pradesh

    (b) Manipur

    (c) Meghalaya

    (d) Uttarakhand

    Himalayan Serow

    • Himalayan Serow resembles a cross between a goat, a donkey, a cow, and a pig.
    • They are herbivores and are typically found at altitudes between 2,000 metres and 4,000 metres (6,500 to 13,000 feet).
    • They are known to be found in eastern, central, and western Himalayas, but not in the Trans Himalayan region.
    • They are a medium-sized mammal with a large head, thick neck, short limbs, long, mule-like ears, and a coat of dark hair.
    • There are several species of Serow s, and all of them are found in Asia.

    Its’ conservation status

    • According to the IUCN, Himalayan Serow s have experienced significant declines in population size, range size and habitat in the last decade, and this is expected to continue due to intensive human impact.
    • Previously assessed as ‘near threatened’, the Himalayan Serow is now been categorised as ‘vulnerable’ in the IUCN Red List of Threatened Species.
    • It is listed under Schedule I of The Wildlife Protection Act, 1972, which provides absolute protection.

    What is so unusual this time?

    • The animal was spotted by locals and wildlife officials at a riverside rocky wall near Hurling village in Spiti, Himachal Pradesh.
    • This is the first recorded human sighting of the Serow in Himachal Pradesh.
    • Serow s are generally not found at this altitude, and never before has a Serow been seen in the Himalayan cold desert.
    • Wildlife officials believe this particular animal may have strayed into the Spiti valley from the Rupi Bhaba Wildlife Sanctuary in adjoining Kinnaur.

  • Issues related to Nursing Sector in India

    The year 2020 has been designated as “International Year of the Nurse and the Midwife”.

    But the nursing education in India displays a grim situation. It suffers poor quality of training, inequitable distribution, and non-standardized practices.

    Nursing sector in India

    • Nurses and midwives will be central to achieving universal health coverage in India.
    • India’s nursing workforce is about two-thirds of its health workforce. Its ratio of 7 nurses per 1,000 population is 43% less than the World Health Organization norm; it needs 2.4 million nurses to meet the norm.
    • The sector is dogged by structural challenges that lead to poor quality of training, inequitable distribution, and non-standardized practices.

    Uneven regulation

    Nursing education in India has a wide array of certificate, diploma, and degree programmes for clinical and non-clinical nursing roles.

    • The Indian Nursing Council regulates nursing education through prescription, inspection, examination, and certification. 91% of the nursing education institutions are private and weakly regulated. The quality of training of nurses is diminished by the uneven and weak regulation.
    • The current nursing education is outdated and fails to cater to the practice needs. The education, including re-training, is not linked to the roles and their career progression in the nursing practice.
    • There are insufficient postgraduate courses to develop skills in specialities and address critical faculty shortages both in terms of quality and quantity.
    • These factors have led to gaps in skills and competencies, with no clear career trajectory for nurses.
    • Multiple entries point to the nursing courses and lack of integration of the diploma and degree courses diminish the quality of training.
    • A common entrance exam, a national licence exit exam for entry into practice, and periodic renewal of licence linked with continuing nursing education would significantly streamline and strengthen nursing education.
    • Transparent accreditation, benchmarking, and ranking of nursing institutions too would improve the quality.
    • The number of nursing education institutions has been increasing steadily but there are vast inequities in their distribution. Around 62% of them are situated in southern India.
    • There is little demand for postgraduate courses. Recognizing the need for speciality courses in clinical nursing 12 PG diploma courses were rolled out but the higher education qualification is not recognized by the recruiters.
    • The faculty positions vacant in nursing college and schools are around 86% and 80%, respectively.

    Gaps in education, services

    • There is a lack of job differentiation between diploma, graduate, and postgraduate nurses regarding their pay, parity, and promotion.
    • The higher qualifications are underutilized, leading to low demand for postgraduate courses.
    • Those with advanced degrees seek employment in educational institutions or migrate abroad which has led to an acute dearth of qualified nurses in the country.
    • Small private institutions with less than 50 beds recruit candidates without formal nursing education. They are offered courses of three to six months for non-clinical ancillary nursing roles and are paid very little.
    • The Indian Nursing Act primarily revolves around nursing education and does not provide any policy guidance about the roles and responsibilities of nurses in various cadres.
    • Nurses in India have no guidelines on the scope of their practice and have no prescribed standards of care and is a major reason for the low legitimacy of the nursing practice and the profession. This may endanger patient safety.
    • The Consumer Protection Act holds only the doctor and the hospital liable for medico-legal issues; nurses are out of the purview of the Act. This is contrary to the practices in developed countries where nurses are legally liable for errors in their work.

    Institutional reforms required

    1. The governance of nursing education and practice must be clarified and made current.
    2. The Indian Nursing Council Act of 1947must be amended to explicitly state clear norms for service and patient care, fix the nurse to patient ratio, staffing norms and salaries.
    3. The jurisdictions of the Indian Nursing Council and the State nursing councils must be explained and coordinated so that they are synergistic.
    4. Incentives to pursue advanced degrees to match their qualification, clear career paths, the opportunity for leadership roles, and improvements in the status of nursing as a profession should be done.
    5. A live registry of nurses, positions, and opportunities should be a top priority to tackle the demand-supply gap in this sector.
    6. The public-private partnership between private nursing schools/colleges and public health facilities is another strategy to enhance nursing education. NITI Aayog has recently formulated a framework to develop a model agreement for nursing education.
    7. The Government has also announced supporting such projects through a Viability Gap Funding.

    Practice Question:

    Q. Discuss the various issues related to nursing sector in India and measures to be taken to address them.

    A Bill that could spell hope

    • The disabling environment prevalent in the system has led to the low status of nurses in the hierarchy of health-care professionals. In fact, nursing has lost the appeal as a career option.
    • The National Nursing and Midwifery Commission Bill currently under consideration should hopefully address some of the issues highlighted.
    • These disruptions are more relevant than ever in the face of the COVID-19 pandemic.

  • Hydroponics: the art of soil-less farming

    This newscard is an excerpt from the original article published in TH.

    Many questions related to agricultural techniques are being asked in the Prelims. UPSC has done away with traditional crop-related questions for the past two years. 

    For example, see this question from CSP 2020:

    Q.What are the advantages of fertigation in agriculture?

    1. Controlling the alkalinity of irrigation water is possible.
      2. Efficient application of Rock Phosphate and all other phosphatic fertilizers is possible.
      3. Increased availability of nutrients to plants is possible.
      4. Reduction in the leaching of chemical nutrients is possible.

    Select the correct answer using the code given below:
    (a) 1, 2 and 3 only

    (b) 1,2 and 4 only

    (c) 1,3 and 4 only

    (d) 2, 3 and 4 only

    What is hydroponics?

    Hydroponics is the cultivation of plants without using soil.

    • Hydroponic flowers, herbs, and vegetables are planted in inert growing media and supplied with nutrient-rich solutions, oxygen, and water.
    • This system fosters rapid growth, stronger yields, and superior quality.
    • When a plant is grown in soil, its roots are perpetually searching for the necessary nutrition to support the plant.
    • If a plant’s root system is exposed directly to water and nutrition, the plant does not have to exert any energy in sustaining itself.
    • The energy the roots would have expended acquiring food and water can be redirected into the plant’s maturation. As a result, leaf growth flourishes as does the blooming of fruits and flowers.

    Why Hydroponics?

    • Plants sustain themselves by a process called photosynthesis. But they do not need soil to photosynthesize.
    • They need the soil to supply them with water and nutrients.
    • When nutrients are dissolved in water they can be applied directly to the plant’s root system by flooding, misting, or immersion.
    • Hydroponic innovations have proven direct exposure to nutrient-filled water can be a more effective and versatile method of growth than traditional irrigation.

    How does hydroponics work?

    • Hydroponic systems work by allowing minute control over environmental conditions like temperature and pH balance and maximized exposure to nutrients and water.
    • It administers nutrient solutions tailored to the needs of the particular plant being grown.
    • They allow you to control exactly how much light the plants receive and for how long.
    • pH levels can be monitored and adjusted. In a highly customized and controlled environment, plant growth accelerates.

    Components of Hydroponics

    To maintain a flourishing hydroponic system, we need to become acquainted with a few components that make it run efficiently.

    (1) Growing media

    • Hydroponic plants are often grown in inert media that support the plant’s weight and anchor its root structure.
    • Growing media is the substitute for soil, however, it does not provide any independent nutrition to the plant.
    • Instead, this porous media retains moisture and nutrients from the nutrient solution which it then delivers to the plant.

    (2) Air stones and air pumps

    • Plants that are submerged in water can quickly drown if the water is not sufficiently aerated. Air stones disperse tiny bubbles of dissolved oxygen throughout your nutrient solution reservoir.
    • These bubbles also help evenly distribute the dissolved nutrients in the solution. Air stones do not generate oxygen on their own.
    • They need to be attached to an external air pump via opaque food grade plastic tubing

    (3) Net pots

    • Net pots are mesh planters that hold hydroponic plants. The latticed material allows roots to grow out of the sides and bottom of the pot, giving greater exposure to oxygen and nutrients.
    • Net pots also provide superior drainage compared to traditional clay or plastic pots.

    Benefits

    By controlling the environment of the plant in hydroponics, many risk factors are reduced:

    • Plants grown in gardens and fields are introduced to a host of variables that negatively impact their health and growth. Fungus in the soil can spread diseases to plants.
    • Wildlife like rabbits can plunder ripening vegetables from your garden.
    • Pests like locusts can descend on crops and obliterate them in an afternoon. Hydroponic systems end the unpredictability of growing plants outdoors and in the earth.
    • Without the mechanical resistance of the soil, seedlings can mature much faster.
    • By eliminating pesticides, hydroponics produces much healthier and high-quality fruits and vegetables. Without obstacles, plants are free to grow vigorously and rapidly.

    Various limitations

    • A hydroponic system isn’t cheap
    • Constant monitoring is required
    • Micro-organisms that are water-based can creep in rather easily
    • Growing a hydroponic garden demands an expertise
    • Production is limited compared to field conditions
    • If a disease appears, all plants in the system will be affected
    • Without soil to serve as a buffer if the system fails plant death will occur rapidly

  • Shola Sky Islands of the Western Ghats

    Tropical montane grasslands (TMG) in the Shola Sky Islands of the Western Ghats have suffered big losses due to invasions by exotic trees.

    Q.In India, which type of forest among the following occupies the largest area?
    (a) Montane Wet Temperate Forest
    (b) Sub – tropical Dry Evergreen Forest
    (c) Tropical Moist Deciduous Forest
    (d) Tropical Wet Evergreen Forest

    Sky Islands

    • “Sky islands” are the tops of tall mountains that become environmentally isolated from each other even if they are close together, geographically speaking.
    • The Western Ghats are a mountain chain in southwest India home to spectacular and unique sky islands.
    • The peaks of the Western Ghats, ranging between 3,000 and 8,500 feet above sea level, host an almost unbelievable array of microclimates, looking like “patches of forests floating in a sea of grasslands.

    What are TMGs?

    • TMG are high elevation grasslands forming only 2% of all grasslands in the world.
    • Among their functions is regulating the global carbon cycle and serving as a source of water to downstream communities.
    • Researchers say grasslands do not benefit from conservation and restoration efforts afforded to tropical montane forests, possibly due to limited information.

    Treasures of Shola

    • One of the specific habitats unique to the sky islands of this area is a type of low-temperature, high-humidity tropical cloud forest full of stunted trees mixed with grasslands called the Shola.
    • The Shola forests of South derive their name from the Tamil word solai, which means a ‘tropical rain forest’.
    • Classified as ‘Southern Montane Wet Temperate Forest’ the Sholas are found in the upper reaches of the Nilgiris, Anamalais, Palni hills, Kalakadu, Mundanthurai and Kanyakumari in the states of Tamil Nadu and Kerala.
    • These forests are found sheltered in valleys with sufficient moisture and proper drainage, at an altitude of more than 1,500 metres.

    Various threats to them

    • Loss of grasslands due to invasive exotic trees is a “novel threat” through the establishment and expansion of exotic tree plantations.
    • These exotic trees include acacias, pines and eucalyptus, shrinking the range sizes of endemic species, including plants, birds, amphibians and mammals.
    • In the Western Ghats, 23% of montane grasslands were reportedly converted into invasive exotic tree cover over a period of 44 years.
    • Attempts to manage invasive exotic trees in montane grasslands incorporated approaches that include prevention and mechanical, chemical and biological control.
    • For invasive species such as Acacia mearnsii that grow rapidly and disperse seeds widely, removing mature trees is often ineffective.

  • Matru Sahyogini Samitis Scheme

    The MP government has issued an order for the appointment of committees led by mothers to ensure better monitoring of services delivered at Anganwadi or day-care centres across the State.

    Matru Sahyogini Samitis

    • Called ‘Matru Sahyogini Samiti’ or Mothers’ Cooperation Committees, these will comprise 10 mothers at each Anganwadi centres.
    • They would be representing the concerns of different sets of beneficiaries under the Integrated Child Development Services, or National Nutrition Mission.
    • Beneficiaries’ would include children between six months to three years, children between three years and six years, adolescent girls and pregnant women and lactating mothers.
    • These mothers will keep a watch on weekly ration distribution to them as well as suggest nutritious and tasteful recipes for meals served to children at the centres.
    • The move is being taken as per the mandate of the National Food Security Act, 2013 (NFSA).

    Its’ functioning

    • The committees will include mothers of beneficiary children as well as be represented by pregnant women and lactating mothers who are enrolled under the scheme.
    • The Anganwadi scheme includes a package of six services delivered at the centres, including supplementary nutrition, health services including vaccination, early education, among others.
    • The Committees will also include a woman panch, women active in the community and eager to volunteer their support to the scheme, teachers from the local school, and women heads of self-help groups (SHG).

    Why such a move?

    • This is in a move that is aimed at strengthening community response to the problem of hunger and malnutrition in the State.
    • With the help of mothers, we will be able to turn anganwadis into a community health system, a nutrition management centre, and spread awareness against social evils.
    • These will turn into a model for local governance as well as allow for greater engagement between communities and the State government.

    Back2Basics: Integrated Child Development Services (ICDS)

    • The ICDS aims to provide food, preschool education, primary healthcare, immunization, health check-up and referral services to children under 6 years of age and their mothers.
    • The scheme was launched in 1975, discontinued in 1978 by the government of Morarji Desai, and then relaunched by the Tenth Five Year Plan.
    • The tenth FYP also linked ICDS to Anganwadi centres established mainly in rural areas and staffed with frontline workers.
    • The ICDS provide for anganwadis or day-care centres which deliver a package of six services including:
    1. Immunization
    2. Supplementary nutrition
    3. Health checkup
    4. Referral services
    5. Pre-school education (Non-Formal)
    6. Nutrition and Health information

    Implementation

    • For nutritional purposes, ICDS provides 500 kilocalories (with 12-15 grams of protein) every day to every child below 6 years of age.
    • For adolescent girls, it is up to 500-kilo calories with up to 25 grams of protein every day.
    • The services of Immunisation, Health Check-up and Referral Services delivered through Public Health Infrastructure under the Ministry of Health and Family Welfare.
