  • Rhino horns are shrinking

    rhino

    The horns of rhinoceroses may have become smaller over time from the impact of hunting, according to a recent study spanning more than five centuries.

    About Indian Rhino

    • The Indian rhinoceros also called the greater one-horned rhinoceros and great Indian rhinoceros is a rhinoceros native to the Indian subcontinent.
    • It is listed as Vulnerable on the IUCN Red List and Schedule I animal in the Wildlife Protection Act, 1972.
    • It once ranged across the entire northern part of the Indian Subcontinent, along the Indus, Ganges and Brahmaputra River basins, from Pakistan to the Indian-Myanmar border.
    • Poaching for rhinoceros horn became the single most important reason for the decline of the Indian rhino.

    Why are Rhinos poached for horns?

    • Ground rhino horn is used in traditional Chinese medicine to cure a range of ailments, from cancer to hangovers, and also as an aphrodisiac.
    • In Vietnam, possessing a rhino horn is considered a status symbol.
    • Due to demand in these countries, poaching pressure on rhinos is ever persistent against which one cannot let the guard down.

  • State Pollution Control Boards (SPCBs)

    pollution

    Context

    • In the fight against air pollution in the Indo Gangetic Plain, there are several important protagonists, none more so than India’s frontline environmental regulators, the State Pollution Control Boards (SPCBs), and the Pollution Control Committees (PCCs) in the Union Territories. There is no future with clean air in which the SPCB’s do not perform at the highest level possible.

    know about State Pollution Control Boards (SPCB)

    • Constituted under Water (Prevention and Control of Pollution) Act, 1974: The SPCBs were initially constituted under the Water (Prevention and Control of Pollution) Act, 1974. Under the Air (Prevention and Control of Pollution) Act, 1981, the SPCB mandate was expanded to include air quality management.
    • New responsibility without capacity: Subsequently, several new environmental regulations added to their roles and functions. Unfortunately, this enhanced mandate has not been matched with increased capacity and capability in the Boards. As environmental indicators such as air quality and water quality worsen in many parts of the country, the Boards are evidently failing to effectively discharge their statutory mandate.

    Analyzing the performance of SPCB’s

    • Poor performance of SPCBs: Over the years, several reports that have been published, including those by the parliamentary standing committee and government committees, have identified reasons for the poor performance of the SPCBs.
    • Experts are excluded from composition: The composition of SPCBs is a matter of serious concern as important stakeholders and those with crucial expertise are missing in most States. Boards are multimember bodies headed by a chairperson and a member secretary. Their decisions and policies guide the day-to-day functioning of the organisation.
    • Conflict of interest: Over 50% of the Board members across the 10 SPCBs and PCC studied represent potential polluters: local authorities, industries, and public sector corporations. They are subject to the SPCB’s regulatory measures, and their overwhelming presence raises fundamental questions around conflicts of interest.
    • SPCBs Does not meet the statutory requirement: At the same time, scientists, medical practitioners, and academics constitute only 7% of the Board members. What is even more worrying is that most Boards do not meet the statutory requirement of having at least two Board members who have knowledge of, and experience in, air quality management.
    • SPCB’s leadership and uncertain tenure: The chairperson and the member secretary do not enjoy a long, stable, and fulltime tenure. In many States, persons in these two posts hold an additional charge in other government departments. Data also show that several chairpersons and member secretaries have held their posts for less than a year. For example, the shortest tenure for a chairperson has been 18 days (Chhattisgarh) and 15 days for a member secretary (Haryana and Uttar Pradesh).
    • Short tenure with multiple roles: With the focus of the leadership of SPCB spread thin across multiple roles and their tenures being short, often they do not even have the time to understand their mandate fully before they are moved out. In such a scenario, long term policy planning, strategic interventions and effective execution aimed at reducing air pollution substantially are extremely difficult.
    • Problem of Understaffing: The SPCBs are critically understaffed. At least 40% of all sanctioned posts are vacant across nine SPCBs/PCCs for which there is data. Vacancy levels in technical positions are as high as 84% in Jharkhand, and over 75% in Bihar and Haryana. An inadequate staff strength forces the Boards to recast their priorities among their various functions.
    • Less regulatory scrutiny: Less staff strength also means weaker regulatory scrutiny and poor impact assessment. For example, given their workload, engineers in Bihar, Jharkhand, Punjab and Uttar Pradesh have less than a day to inspect, evaluate and decide on each consent application. With Board staff running on empty, this is clearly an unsustainable situation.

    pollution

    What are the recommendations for effective SPCBs?

    • Addressing Leadership and human resource needs: Strengthening manpower at the SPCBs will not only require hiring new resources, but also training existing staff by leveraging institutions such as the Indian Institutes of Technology, NEERI, and others. These in-service training programs would also serve as an incentive for staff both new and existing.
    • Better Pay structures: The Pay structure need to be revised to align with sectoral norms to ensure that SPCBs are not regularly losing trained manpower to industry and other sectors.
    • Modern infrastructure: The infrastructure of PCBs also needs to be improved along with manpower i.e., facilities such as adequate computers, improved lab facility etc. The instruments used for monitoring are not maintained properly or outdated. Sometimes labs are also not equipped enough to do the necessary analysis.
    • Expert should lead the SPCBs: It is imperative for their effective functioning that States should nominate to leadership positions, individuals of technical expertise and distinguished service such that effective decision making can be carried out.
    • Providing the fixed tenure: They should be appointed for a fixed tenure and in full-time roles, with the sword of removal or termination not hanging over their heads.
    • Reduction is composition for effective functioning: The size of the boards themselves may also be reduced to aid in effective functioning, with preference in membership given to technical experts, as is the international best practice. These moves would ensure that the Boards function effectively as independent agencies, as envisioned in their foundational legislation.

    pollution

    Read the basics-Air pollution

    • Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere.
    • Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide. Outdoor and indoor air pollution cause respiratory and other diseases and are important sources of morbidity and mortality.

    Conclusion

    • Given the scale and causes of air pollution in India, multidisciplinary expertise is needed to tackle it; there must also be an explicit focus on health while designing air pollution policy. The lack of expertise and skewed representation of stakeholders on the Boards can only be a hindrance to effective policy making.

  • Species in news: Amur Falcon

    falcon

    The Amur falcons have begun to arrive in Manipur after travelling over 20,000 km.

    Amur Falcon

    • The Amur falcon (Falco amurensis) is a small raptor of the falcon family.
    • It breeds in south-eastern Siberia and Northern China before migrating in large flocks across India and over the Arabian Sea to winter in Southern and East Africa.

    How it migrates?

    • Locally known as Akhuipuina, the bird arrives mainly in Manipur and Nagaland on its southbound migration from breeding grounds in North China, Eastern Mongolia and far-east Russia.
    • They travel to Manipur en-route to its wintering grounds in South Africa.
    • The one-way journey via India is about 20,000 km long and the birds do this twice a year.
    • They spend three-four weeks in many parts of Manipur to build fat reserves by preying on termites that emerge around this time.

    Conservation status

    • It is protected under the Wildlife Protection Act 1972 and included under its Schedule IV.
    • It is listed in the IUCN Red list as Least Concern.
    • Hunting of the birds or possessing its meat is punishable with imprisonment up to three years or a fine up to Rs 5,000.
    • In 2018, the forest department started a conservation programme by radio-tagging the birds to study their migratory route.

  • Dolphins return to the Ganga

    dolphin

    Dolphins have started coming back to the Ganga with improvement in the quality of the river water made possible by the Namami Gange Programme.

    About Gangetic Dolphin

    • The Gangetic river system is home to a vast variety of aquatic life, including the Gangetic dolphin (Platanista gangetica).
    • It is one of five species of river dolphin found around the world.
    • It is found mainly in the Indian subcontinent, particularly in Ganga-Brahmaputra-Meghna and Karnaphuli-Sangu river systems.
    • An adult dolphin could weigh between 70 kg and 90 kg. The breeding season of the Gangetic dolphin extends from January to June.
    • They feed on several species of fishes, invertebrates etc.

    Threats to Gangetic dolphins

    • The construction of dams and barrages and increasing pollution has led to a decline in the population of aquatic animals in the rivers in general and of dolphins in particular.
    • Aquatic life is an indicator of the health of river ecosystems.
    • As the Gangetic dolphin is at the top of the food chain, protecting the species and its habitat will ensure

    How are they conserved?

    • Although efforts to save them were started in the mid-1980s, the estimates suggest the numbers have not risen as a result.
    • The Gangetic dolphin remains listed as Endangered by the IUCN.
    • After the launch of Ganga Action Plan in 1985, the government on November 24, 1986, included Gangetic dolphins in the First Schedule of the Indian Wildlife (Protection), Act 1972.
    • This was aimed at checking hunting and providing conservation facilities such as wildlife sanctuaries.
    • For instance, Vikramshila Ganges Dolphin Sanctuary was established in Bihar under this Act.
    • It has been recognized as National Aquatic Animal of India.

    Policy moves for conservation

    • The government had prepared The Conservation Action Plan for the Ganges River Dolphin 2010-2020.
    • The National Mission for Clean Ganga celebrates October 5 as National Ganga River Dolphin Day.
    • There is also Project Dolphin on the lines of Project Tiger, which has helped increase the tiger population.

  • What is Air Quality Index (AQI)?

     

    air

     

     

    Air Quality Index (AQI)

    • AQI measures how safe the air around you is for breathing. Organizations that report AQI measure the density of various pollutants in the air (such as PM2.5, PM10, nitrogen dioxide, ozone, etc) at different monitoring stations.
    • The widely-used National Air Quality Index (NAQI) given by the Central Pollution Control Board is a 24-hour average.
    • Its unit is micrograms per cubic meter.
    • A particular amount of one pollutant may not be as harmful as the same amount of another pollutant.
    • So, each pollutant’s quantity in the air is adjusted to a common scale (say, 0 to 500) that works for all pollutants.
    • Finally, the pollutant with the worst sub-index determines the AQI for that time and location.

    What are NAAQ standards?

    • The mandate provided to the Central Pollution Control Board (CPCB) under the Air (Prevention and Control of Pollution) Act empowers it to set standards for the quality of air.
    • Hence the current National Ambient Air Quality Standards were notified in November 2009 by the CPCB.
    • Prior to this, India had set Air Quality standards in 1994, and this was later revised in 1998.
    • The 2009 standards further lowered the maximum permissible limits for pollutants and made the standards uniform across the nation.
    • Earlier, less stringent standards were prescribed for industrial zones as compared to residential areas.

    Pollutants covered:

    • Sulphur Dioxide (SO2)
    • Nitrogen Dioxide (NO2),
    • Particulate Matter (size less than 10 µm) or PM 10
    • Particulate Matter (size less than 2.5 µm) or PM2.5
    • Ozone (O3)
    • Carbon Monoxide (CO)
    • Ammonia (NH3)

    (Air Pollutants that most of us NEVER heard of)

    • Lead
    • Benzene (C6H6)
    • Benzo(a)Pyrene (BaP)
    • Arsenic(As)
    • Nickel (Ni)

    What are Initiatives taken by India for Controlling Air Pollution?

    • System of Air Quality and Weather Forecasting and Research (SAFAR) Portal
    • Air Quality Index: AQI has been developed for eight pollutants viz. PM2.5, PM10, Ammonia, Lead, nitrogen oxides, sulphur dioxide, ozone, and carbon monoxide.
    • Graded Response Action Plan
    • For Reducing Vehicular Pollution: BS-VI Vehicles, Push for Electric Vehicles (EVs),Odd-Even Policy as an emergency measure
    • New Commission for Air Quality Management
    • Subsidy to farmers for buying Turbo Happy Seeder (THS) Machine

  • Climate Crisis, India’s Solution – Mission LiFE

    Mission LiFE

    Context

    • Prime Minister Narendra Modi on October 20 unveiled the action plan for Mission LiFE (Lifestyle for Environment), an India-led global mass movement that will nudge individuals and communities for action to protect and preserve the environment.

    What is LiFE?

    • Importance of individual efforts: Mission LiFE makes environmental protection and conservation a participative process and recognizes the importance of each effort no matter how small or big to save the environment both at the level of the individual and at the level of the community.
    • Chaning utilization attitude: The idea promotes an environmentally conscious lifestyle that focuses on ‘mindful and deliberate utilization’ instead of ‘mindless and wasteful consumption’.
    • Creating social networks: The LIFE Movement aims to utilize the power of collective action and nudge individuals across the world to undertake simple climate-friendly actions in their daily lives. The LIFE movement, additionally, also seeks to leverage the strength of social networks to influence social norms surrounding climate.
    • Creating Pro-planet people: The Mission plans to create and nurture a global network of individuals, namely ‘Pro-Planet People’ (P3), who will have a shared commitment to adopt and promote environmentally friendly lifestyles.
    • Seeks to behavioral change and individual actions: Through the P3 community, the Mission seeks to create an ecosystem that will reinforce and enable environmentally friendly behaviors to be self-sustainable. LIFE recognizes that small individual actions can tip the balance in the planet’s favour.

    Do you know pro-planet initiatives worldwide?

    • Denmark:  Denmark promotes the use of bicycles by limiting parking within the city Centre and providing exclusive bike lanes.
    • Japan: Japan has its unique “walk-to-school” mandate, which has been in practice since the early 1950s.

    Mission LiFE

    Why is the need for such movement?

    • Wrong perception about conservation: Environment protection, has for far too long been perceived as a policy issue by the general masses. There has been a perception that only national governments and international organizations can do something to protect the Earth and environment.

    How mission LiFE will be helpful?

    • Mindless consumption of resources: The human race is plundering Planet Earth at a pace that far outstrips its capacity and ability to support life. A recent study says that if the current rate of consumption were to continue, by 2050, humans would need two more planets, in addition to the Earth, to continue to exist.
    • Declining natural resources and beauty: This means that we could be staring at major climatic crises in the years to come and our future generations may never get to experience the beauty of nature, the glaciers, the oceans, the snow and the rivers, that we have been fortunate to see and experience.
    • Unsustainable consumption pattern: What threatens our existence more than anything else is the pace at which we are producing and consuming. The consumption pattern of the world is mindless and pays scant regard to the environment.
    • Attitude change through mission LiFE: Mission LiFE tries to remind the world that the mindset of “use and throw” must immediately be replaced by “reduce, reuse and recycle” so that our scarce resources are not overexploited, and the world doesn’t crumble under the weight of all the waste that it is generating by the second.
    • Small efforts big Impact: Mission LiFE is a philosophy which shows how this can be made possible. It shows the power of small efforts to make big impacts. It believes in the individual’s capacity to change the world. It is the mantra to reverse historical and cultural wrongs wrecked upon the environment. Mission LiFE is the call to action for citizens and governments to save the planet.

    Mission LiFE

    What are India’s efforts for LiFE?

    • Environment friendly culture: In India, the cultural ethos of limiting needs and treating the environment and its resources with reverence has produced very visible results. India constitutes 17 per cent of the world’s population, but our contribution to global carbon emissions is only four per cent.
    • Less carbon footprint per head: Against the developed world’s carbon footprint of four tonnes per head, the carbon footprint of an average Indian counts to only 1.5 tonnes.
    • Multiple global initiatives: Despite not being part of the problem, with numerous global initiatives such as the International Solar Alliance, the One Sun One World One Grid initiative, and the Coalition for Disaster Resilient Infrastructure, India has taken the lead in presenting and building solutions for the world by bringing the global community together.
    • Focus on collective actions of world community: The need to build these global alliances to fight climate change stems from the understanding that only collective action can save the world from the vagaries of climate change that are increasingly becoming a reality and are rising in ferocity.
    • Mindful utilization of resources: India offering knowledge from its religious and cultural ethos to the world, Mission LiFE aims to pull the world away from a “mindless and destructive” consumerist approach towards a “mindful and deliberate utilization” of resources. It is also, at the same time, an effort to prevent India from heading that way.
    • Shift towards sustainable policies: India is already working towards building a circular economy and moving towards a stage where all our energy requirements are met through the use of renewables. Our policies are all aligned towards ensuring sustainable development, where nature is not disregarded for development but where the most marginalized are not left to their destiny by denying them development.

    Mission LiFE

    Conclusion

    • Actions against climate change is not just a fervent hope but an emergent necessity. Through mission LiFE India is trying to portray climate crisis from individual perspective. Mission LiFE has a potential to transform climate change movement into the mass movement.

    Mains Question

    How Mission LiFE will help in conservation of Environment? Critically analyze the India’s efforts to make LiFE a successful mission?

  • CBG: Renewable energy revolution

    cbg

    Context

    • The beginnings of a renewable energy revolution rooted in agriculture are taking shape in India with the first bio-energy plant of a private company in Sangrur district of Punjab having commenced commercial operations on October 18. It will produce Compressed Biogas (CBG) from paddy straw, thus converting agricultural waste into wealth.

    Background

    • Stubble burning every year in north and northwest: It has become common practice among farmers in Punjab, Haryana and western Uttar Pradesh to dispose of paddy stubble and the biomass by setting it on fire to prepare fields for the next crop, which has to be sown in a window of three to four weeks. This is spread over millions of hectares.
    • Resultant smog polluting environment: The resultant clouds of smoke engulf the entire National Capital Territory of Delhi and neighbouring States for several weeks between October to December. This plays havoc with the environment and affects human and livestock health.
    • Stubble burning practice spreading rapidly across the country: Though paddy stubble burning in northwest India has received a lot of attention because of its severity of pollution, the reality is that crop residue burning is spreading even to rabi crops and the rest of the country. Unless these practices are stopped, the problem will assume catastrophic proportions.

     What is Stubble Burning?

    • Stubble (parali) burning is a method of removing paddy crop residues from the field to sow wheat from the last week of September to November.
    • It is usually required in areas that use the combined harvesting method which leaves crop residue behind.
    • This practice mostly carried out in Punjab, Haryana and UP contributes solely to the grave winter pollution in the national capital.

    cbg

    How stubble burning impacts environment and Human health?

    • Deteriorates air quality: The process of burning farm residue is one of the major causes of air pollution in parts of north India, deteriorating the air quality.
    • Source of various harmful gases: Stubble burning is a significant source of carbon dioxide (CO2), volatile organic compounds (VOCs), nitrogen oxides (NOx) and hydrocarbons (HC).
    • Air Pollution: Stubble burning emits toxic pollutants in the atmosphere containing harmful gases like Carbon Monoxide (CO), methane (CH4), carcinogenic polycyclic aromatic hydrocarbons, volatile organic compounds (VOC). These pollutants disperse in the surroundings and eventually affect air quality and people’s health by forming a thick blanket of smog. Along with vehicular emissions, it affects the Air Quality Index (AQI) in the national capital and NCR.
    • Soil degradation: Soil becomes less fertile and its nutrients are destroyed when the husk is burned on the ground. Organic content of soil is completely destroyed. Stubble burning generates heat that penetrates into the soil, causing an increase in erosion, loss of useful microbes and moisture.

    cbg

    Some of the measures taken by Government for the effective prevention and control of stubble burning

    • The Commission for Air Quality Management: The Commission for Air Quality Management in National Capital Region and Adjoining Areas (CAQM) had developed a framework and action plan for the effective prevention and control of stubble burning,
    • In-situ management: The framework/action plan includes in-situ management, i.e., incorporation of paddy straw and stubble in the soil using heavily subsidized machinery (supported by crop residue management (CRM) Scheme of the Ministry of Agriculture and Farmers Welfare).
    • Ex-situ management: Ex-situ CRM efforts include the use of paddy straw for biomass power projects and co-firing in thermal power plants, and as feedstock for 2G ethanol plants, feed stock in CBG plants, fuel in industrial boilers, waste-to-energy (WTE) plants, and in packaging materials, etc.
    • Awareness generation programme: Additionally, measures are in place to ban stubble burning, to monitor and enforce this, and initiating awareness generation.
    • Project by NITI Aayog along with FAO: NITI Aayog approached FAO India in 2019 to explore converting paddy straw and stubble into energy and identify possible ex-situ uses of rice straw to complement the in-situ programme.
    • Rice straw for producing CBG: A techno-economic assessment of energy technologies suggested that rice straw can be cost-effective for producing CBG and pellets. Pellets can be used in thermal power plants as a substitute of coal and CBG as a transport fuel.
    • SATAT initiative: With 30% of the rice straw produced in Punjab, a 5% CBG production target set by the Government of India scheme, “Sustainable Alternative Towards Affordable Transportation (SATAT)” can be met. It could also increase local entrepreneurship, increase farmers’ income and reduce open burning of rice straw.
    • Encouraging private players to produce CBG more and reduce CO2 emissions: Verbio India Private Limited, a 100% subsidiary of the German Verbio AG, got approval from the Punjab government in April 2018 to set up a bio-CNG project that will utilise about 2.1 lakh tonnes of a total of 18.32 million tonnes of paddy straw annually. The plant will use one lakh tonnes of paddy straw produced from approximately 16,000 hectares of paddy fields. Paddy residue will be collected from this year to produce 33 tons of CBG and 600-650 tonnes of fermented organic manure/slurry per day this will reduce up to 1.5 lakh tonnes of CO2 emissions per year.

    FAO Study on developing crop residue supply chain

    • Use of Rice straw: In technical consultations with the public and private sectors, the FAO published its study on developing a crop residue supply chain in Punjab that can allow the collection, storage and final use of rice straw for other productive services, specifically for the production of renewable energy.
    • Required Investment and benefits farmers: The results suggest that to mobilise 30% of the rice straw produced in Punjab, an investment of around ₹2,201 crore ($309 million) would be needed to collect, transport and store it within a 20-day period. This would reduce greenhouse gas (GHG) emissions by about 9.7 million tonnes of CO2 equivalent and around 66,000 tonnes of PM2.5. Further, depending on market conditions, farmers can expect to earn between ₹550 and ₹1,500 per ton of rice straw sold, depending on market conditions.

    Interesting to read: Compressed Bio Gas (CBG)

    • Biogas is produced naturally through a process of anaerobic decomposition from waste / bio-mass sources like agriculture residue, cattle dung, sugarcane press mud, municipal solid waste, sewage treatment plant waste, etc.
    • After purification, it is compressed and called CBG, which has a pure methane content of over 95%.
    • CBG is exactly similar to the commercially available natural gas in its composition and energy potential.
    • With calorific value (~52,000 KJ/kg) and other properties similar to CNG, CBG can be used as an alternative, renewable automotive fuel.
    • Given the abundance of biomass in the country, CBG has the potential to replace CNG in automotive, industrial and commercial uses in the coming years.

    Conclusion

    • Encouraging private players for producing CBG appears to be a first win-win initiative in the form of environmental benefits, renewable energy, value addition to the economy, farmers’ income and sustainability. This initiative is replicable and scalable across the country and can be a game changer for the rural economy.

    Mains Question

    Q. What is Stubble burning? Discuss the measures taken by Government for the effective prevention and control of stubble burning and producing CBG could be a win-win situation.

  • What is Post-Disaster Needs Assessment (PDNA)?

    pdna

    Post-Disaster Needs Assessment (PDNA) is now being done simultaneously in Assam, Himachal Pradesh, Gujarat, Karnataka, Jharkhand, Maharashtra, Odisha and Meghalaya.

    Why in news?

    • PDNA is now being used to evaluate the financial and social cost of local disasters in eight states in India.
    • These states all experienced severe flooding in the last few months.
    • The results of these assessments are likely to come out next month.

    What is PDNA?

    • PDNA is an internationally accepted methodology for determining the physical damages, economic losses, and costs of meeting recovery needs after a natural disaster through a government-led process.
    • It is an international framework for assessing losses and damages in the aftermath of a disaster.
    • The framework helps get recovery and reconstruction efforts right following a disaster.
    • Globally, of the 55 PDNAs conducted worldwide since 2008, only two droughts — one in Malawi and the other Marshall Islands in 2016 — were of slow-onset disasters.

    Components of PDNA

    • PDNA includes a calculation of the disaster’s impact on Gross Domestic Product, the balance of payment and fiscal budget.
    • Secondly, how this affects the flow of revenue to multiple sectors is evaluated.
    • For example, the number of farmers’ income affected per damaged acre of land and the livelihoods lost.
    • Overall, a quantitative assessment is additionally done on the social and environmental impact of the disaster.

    History of PDNA in India

    • This is not the first time PDNA has been conducted in India.
    • It was first adopted during the Kerala floods of 2018 and again during the cyclone in Odisha in 2019, both unprecedented disasters.
    • Until now, the assessment was only limited to massive disasters that required international funding from the World Bank, the Asian Development Bank and the United Nations.

    15th Finance Commission provision

    • The 15th finance commission report of 2021, for the first time, made a provision for recovery and reconstruction in the national disaster management budget, which is at the core of the PDNA.
    • The states did not receive international funding to do the current ongoing PDNAs, as they are expected to take the money from the budget.
