The World Drug Report 2021: UNODC

Why in News

Recently, the United Nations Office on Drugs and Crime (UNODC), in its World Drug Report 2021, has highlighted that the lockdown restrictions during Covid-19 have accelerated drug trafficking using the Internet.

  • By drugs, the Report refers to substances controlled under international drug control conventions, and their non-medical use.

Key Points

  • Data Analysis:
    • Between 2010-2019, the number of people using drugs increased by 22%, owing in part to an increase in the global population.
    • Around 275 million people used drugs worldwide last year, while over 36 million people suffered from drug use disorders.
    • Opioids continue to account for the largest burden of disease attributed to drug use.
    • A rise in the non-medical use of pharmaceutical drugs was also observed during the coronavirus pandemic.
  • Cannabis is More Potent but Fewer Young People See it as Harmful:
    • In the last 24 years, cannabis potency had increased as much as four times in some parts, even as the percentage of adolescents who perceived the drug as harmful fell by as much as 40%.
      • The major psychoactive constituent in cannabis, Δ9-THC, is responsible for the development of mental health disorders, in the long-term.
    • Reason: Aggressive marketing of cannabis products and promotion through social-media channels.
  • Rising Web-based Sales Could Transform Global Drug Use Patterns:
    • Access to drugs has also become simpler than ever with online sales, and major drug markets on the dark web are now worth some $315 million annually.
    • In Asia, China and India are mainly linked to shipment of drugs sold on the 19 major darknet markets analysed over 2011-2020.
    • Cannabis dominates drug transactions on Dark web and on clear web involves sale of Narcotic Drugs and Psychotropic Substances (NDPS) and substances used in the manufacture of synthetic drugs.

  • Impact of Covid-19:
    • Socio Economic impact:
      • The Covid-19 crisis has pushed more than 100 million people into extreme poverty, and has greatly exacerbated unemployment and inequalities, as the world lost 255 million jobs in 2020.
      • Mental health conditions are also on the rise worldwide. Such socioeconomic stressors have likely accelerated demand for the drugs.
    • Positive Trend:
      • A rise in the use of technology during the pandemic has also triggered innovation in drug prevention and treatment services, through more flexible models of service delivery such as telemedicine, enabling healthcare professionals to reach and treat more patients.
      • The number of new NDPS emerging on the global market fell from 163 in 2013, to 71 in 2019.
      • The pharmaceutical opioids used to treat people with opioid use disorders have become increasingly accessible, as science-based treatment has become more broadly available.
  • Reasons for Increase in Drug Use:
    • Drug traffickers have quickly recovered from initial setbacks caused by lockdown restrictions and are operating at pre-pandemic levels once again.
      • It is driven in part by a rise in the use of technology and cryptocurrency payments, operating outside the regular financial system.
    • Contactless drug transactions, such as through the mail, are also on the rise, a trend possibly accelerated by the pandemic.
    • Vendors play a cat-and-mouse game with law enforcement by marketing their products as “research chemicals” or advertising “custom synthesis”.
  • Suggestions:
    • Combating misinformation on the impact of the use of cannabis products is crucial.
    • Awareness-raising and communication efforts that disseminate scientific information without stigmatizing people.
    • Increasing the capacity of law enforcement agencies to address drug trafficking over the darknet remains a priority.
    • Joint responses by Governments and the private sector can involve controlling and removing advertisements and listings of illegal drugs on the Internet.
    • Continuously update scientific standards to keep abreast of the acceleration of Internet-based services.

United Nations Office on Drugs and Crime

  • It was established in 1997 and was named as a United Nations Office on Drugs and Crime (UNODC) in 2002.
  • It acts as the Office for Drug Control and Crime Prevention by combining the United Nations International Drug Control Program (UNDCP) and the Crime Prevention and Criminal Justice Division of the United Nations Office at Vienna.

Relate International Initiatives

  • International Day Against Drug Abuse and Illicit Trafficking is celebrated every year on 26th June.
  • Single Convention on Narcotic Drugs, 1961.
  • The Convention on Psychotropic Substances, 1971.
  • The United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, 1988.

Vulnerability of India

  • India is vulnerable to the trafficking of narcotics as it is sandwiched between the 'Golden Crescent' and the 'Golden Triangle', the major opium production regions in the world.
  • The Golden Crescent region of the South comprises Afghanistan, Iran and Pakistan. The Golden Triangle is the area where the borders of Thailand, and meet at the confluence of the Ruak and Mekong rivers.

FATF Retains Pakistan on Grey List

Why in News

The Financial Action Task Force (FATF) decided to retain Pakistan on “increased monitoring list’.

  • “Increased monitoring list” is another name for the Grey List.

Key Points

  • Background:
    • The FATF had issued the 27-point action plan after placing Pakistan on the ‘Grey List’ in June 2018. The action plan pertains to curbing money laundering and terror financing.
    • During the October-2020 Plenary, due to the Covid-19 pandemic, Pakistan was given an extension for full compliance with the 27-point action plan till February 2021.
      • It had then not fully complied with 6 of the 27 directives.
    • In February 2021, FATF acknowledged Pakistan’s significant progress in combating terrorism, however it was still to fully comply with three of the 27-point action plan.
      • The three points pertained to effective steps in terms of financial sanctions and penalties against the terror funding infrastructure and the entities involved.
  • About:
    • The FATF said Pakistan had failed to take appropriate action against UN-designated terrorists such as 26/11 accused Hafiz Saeed and JeM chief Masood Azhar. However, Pakistan has completed 26 of the 27 action items.
    • The FATF encourages Pakistan to continue to make progress to address as soon as possible the one remaining Countering Finance of Terrorism (CFT)-related item by demonstrating that Terror Financing investigations and prosecutions target senior leaders and commanders of UN-designated terrorist groups.
    • In addition, the FATF has handed down another 6-point list of tasks mainly on money laundering actions to be completed as well.
      • Pakistan is expected to amend its Money-Laundering Act, crackdown on Designated Non-Financial Businesses and Professions (DNFBPs) like real estate agencies and gemstone traders, confiscate and freeze assets of money laundering entities and monitor businesses for proliferation financing, with sanctions for non-compliance.
  • Significance:
    • In Pakistan's case, the FATF has taken cognisance of the inaction against several banned organisations involved in raising funds for terror activities and those linked to global terrorists like Jaish-e-Mohammed chief Masood Azhar and Lashkar-e-Taiba’s Hafiz Saeed and its operations chief Zaki-Ur Rahman Lakhvi.
    • On several occasions, India has also raised the involvement of elements within Pakistan in a number of terror cases, including the 26/11 Mumbai and Pulwama attacks.
    • Perpetual containment of Pakistan on the grey list of FATF would further pressurise Pakistan to take adequate measures to prevent such terrorist attacks on India from its soil.
    • Unlike the next level “blacklist”, greylisting carries no legal sanctions, but it attracts economic strictures and restricts a country’s access to international loans.
      • Pakistan’s Foreign Minister had estimated a loss of $10 billion annually to the Pakistani economy for every year Pakistan has been on the greylist.

Financial Action Task Force

  • About:
    • It is an inter-governmental body established in 1989 during the G7 Summit in Paris.
    • The FATF assesses the strength of a country’s anti-money laundering and anti-terror financing frameworks, however it does not go by individual cases.
  • Objectives:
    • To set standards and promote effective implementation of legal, regulatory and operational measures for combating money laundering, terrorist financing and other related threats to the integrity of the international financial system.
  • Headquarters:
  • Member Countries:
    • The FATF currently has 39 members including two regional organisations — the European Commission and Gulf Cooperation Council. India is a member of the FATF.
  • Lists under FATF:
    • Grey List:
      • Countries that are considered safe haven for supporting terror funding and money laundering are put in the FATF grey list.
      • This inclusion serves as a warning to the country that it may enter the blacklist.
    • Black List:
      • Countries known as Non-Cooperative Countries or Territories (NCCTs) are put in the blacklist.
      • These countries support terror funding and money laundering activities.
      • The FATF revises the blacklist regularly, adding or deleting entries.
  • Sessions: The FATF Plenary is the decision making body of the FATF. It meets three times per year.

Agristack: The New Digital Push in Agriculture

Why in News

Recently, the Ministry of Agriculture has signed a Memorandum of Understanding with Microsoft to run a pilot programme for 100 villages in 6 states.

  • The MoU requires Microsoft to create a ‘Unified Farmer Service Interface’ through its cloud computing services.
  • This comprises a major part of the ministry’s plan of creating ‘AgriStack’ (a collection of technology-based interventions in agriculture), on which everything else will be built.

Key Points

  • About AgriStack:
    • It is a collection of technologies and digital databases that focuses on farmers and the agricultural sector.
    • AgriStack will create a unified platform for farmers to provide them end to end services across the agriculture food value chain.
    • It is in line with the Centre’s Digital India programme, aimed at providing a broader push to digitise data in India, from land titles to medical records.
    • Under the programme, each farmer will have a unique digital identification (farmers’ ID) that contains personal details, information about the land they farm, as well as production and financial details.
      • Each ID will be linked to the individual's digital national ID Aadhaar.
  • Need:
    • At present, the majority of farmers across India are small and marginal farmers with limited access to advanced technologies or formal credit that can help improve output and fetch better prices.
    • Among the new proposed digital farming technologies and services under the programme include sensors to monitor cattle, drones to analyse soil and apply pesticide, may significantly improve the farm yields and boost farmers' incomes.
  • Potential Benefits:
    • Problems such as inadequate access to credit and information, pest infestation, crop wastage, poor price discovery and yield forecasting can be sufficiently addressed by use of digital technology.
    • It will also fuel innovation and breed investment towards the agricultural sector and augment research towards more resilient crops.
  • Concerns:
    • Absence of a Data Protection Legislation:
      • In its absence, it might end up being an exercise where private data processing entities may know more about a farmer’s land than the farmer himself and they would be able to exploit farmers’ data to whatever extent they wish to.
    • Commercialisation:
      • The formation of ‘Agristack’ will imply commercialisation of agriculture extension activities as they will shift into a digital and private sphere.
    • Absence of Dispute Settlement:
      • The MoUs provide for physical verification of the land data gathered digitally, but there is nothing on what will be the course of action if disputes arise, especially when historical evidence suggests that land disputes take years to settle.
    • Privacy and Exclusion Issues:
      • Given that the proposed farmer ID will be Aadhaar-seeded, further issues of privacy and exclusion would emerge.
      • Several researchers have demonstrated the vulnerability of the Aadhaar database to breaches and leaks, while Aadhaar-based exclusion in welfare delivery has also been well documented in different contexts.
      • Also, making land records the basis for farmer databases would mean excluding tenant farmers, sharecroppers and agricultural labourers.
        • Data shows that the population of farm labourers has outstripped that of farmers and cultivators.

Way Forward

  • There is no denial that there is potential in data and technology in empowering farmers but only when the flow of information is balanced.
  • The private firms working on pilot projects must effectively cooperate with state governments to reconcile the differences over land ownership.
  • The government should move ahead with the project based on the results obtained from pilot trails.

African Swine Fever

Why in News

Nagaland has not reported fresh cases of African Swine Flu in the last two weeks.

  • The disease was first reported in November-December, 2019 from the areas of China bordering Arunachal Pradesh.
  • Earlier in April 2020, there were reported deaths of pigs due to the Classical Swine Fever (CSF).

Key Points

  • About:
    • It is a highly contagious and fatal animal disease that infects and leads to an acute form of hemorrhagic fever in domestic and wild pigs.
    • Other manifestations of the disease include high fever, depression, anorexia, loss of appetite, hemorrhages in the skin, vomiting and diarrhoea among others.
    • It was first detected in Africa in the 1920s.
      • Historically, outbreaks have been reported in Africa and parts of Europe, South America, and the Caribbean.
      • However, more recently (since 2007), the disease has been reported in multiple countries across Africa, Asia and Europe, in both domestic and wild pigs.
    • The mortality is close to 100% and since the fever has no cure, the only way to stop its spread is by culling the animals.
    • ASF is not a threat to human beings since it only spreads from animals to other animals.
    • ASF is a disease listed in the World Organisation for Animal Health (OIE) Terrestrial Animal Health Code and thus, reported to the OIE.
  • Classical Swine Fever:
    • CSF, also known as hog cholera, is an important disease of pigs.
    • It is one of the most economically-damaging pandemic viral diseases of pigs in the world.
    • It is caused by a virus of the genus Pestivirus of the family Flaviviridae, which is closely related to the viruses that cause bovine viral diarrhoea in cattle and border disease in sheep.
    • Mortality is 100%.
    • Recently, the ICAR-IVRI developed a Cell Culture CSF Vaccine (live attenuated) using the Lapinized Vaccine Virus from foreign strain.
      • The new vaccine has been found to induce protective immunity from day 14 of the Vaccination till 18 Months.

World Organisation for Animal Health

  • OIE is an intergovernmental organisation responsible for improving animal health worldwide.
  • It has 182 Member Countries. India is one of the member countries.
  • OIE develops normative documents relating to rules that Member Countries can use to protect themselves from the introduction of diseases and pathogens. One of them is the Terrestrial Animal Health Code.
  • OIE standards are recognised by the World Trade Organization as reference international sanitary rules.
  • It is headquartered in Paris, France.

Link between Air Quality and Covid-19

Why in News

For the first time, a pan-India study has found a direct correlation between air pollution and Covid-19.

  • The study found that areas with poor air quality and higher emissions of particulate matter (PM) 2.5 are more likely to have Covid-19 infections and related deaths.

Particulate Matter (PM) 2.5

  • It is an atmospheric particulate matter of diameter of fewer than 2.5 micrometres, which is around 3% the diameter of a human hair.
    • It is very small and can only be detected with the help of an electron microscope.
  • It causes respiratory problems and also reduces visibility. It is an endocrine disruptor that can affect insulin secretion and insulin sensitivity, thus contributing to diabetes.
  • These particles are formed as a result of burning fuel and chemical reactions that take place in the atmosphere. Natural processes such as forest fires also contribute to PM2.5 in the air.
  • These particles are also the primary reason for the occurrence of smog.

Key Points

  • About:
  • Components:
    • The study involves three kinds of data sets—
      • National Emission Inventory (NEI) of PM2.5 for 2019, developed by the scientists;
      • Number of Covid-19 positive cases and corresponding death as of 5th November, 2020.
      • Air quality index data (in-situ observations).
  • Important Observations:
    • The study titled ‘Establishing a link between fine particulate matter (PM2.5) zones and Covid-19 over India based on anthropogenic emission sources and air quality data’ dealt with how people living in highly polluted areas are more vulnerable to coronavirus infections.
    • The regions using huge amounts of fossil fuels such as petrol, diesel and coal by combustion in transport and industrial activities also experience a far higher number of Covid-19 cases.
      • For Example, the highest numbers of Covid-19 cases are found in States like Maharashtra, Uttar Pradesh, Delhi and Gujarat, where exposure to the prolonged high concentration of PM2.5 is relatively high, especially in the cities, due to overuse of fossil fuel.
      • Mumbai and Pune are among hotspots where high air pollution from the transport and industrial sectors is related to a higher number of Covid-19 cases and deaths.
    • There is also evidence that the novel coronavirus sticks to fine particles like PM2.5 allowing them to move from one part to another by making the airborne transmission of Covid-19 more effective.
  • Impact:
    • When human-induced emissions are added combined with the double impact of the Covid-19 virus, the damage to lungs will be much faster and worsen health conditions.
    • The study results will help slow down the spread of the virus by providing more preventive steps and resources in areas with high pollution levels for present situations as well as for future possibilities.
  • Solution:
  • Other Initiatives to Reduce Air Pollution:

Air Quality Index (AQI)

  • The AQI is an index for reporting daily air quality.
  • It focuses on health effects one might experience within a few hours or days after breathing polluted air.
  • AQI is calculated for eight major air pollutants:
    • Ground-level ozone,
    • PM10,
    • PM2.5,
    • Carbon monoxide,
    • Sulfur dioxide,
    • Nitrogen dioxide,
    • Ammonia,
    • Lead,
  • Ground-level ozone and airborne particles are the two pollutants that pose the greatest threat to human health in India.

Ambergris

Why in News

Recently, the Mumbai Police has arrested five people and seized nearly 9 kg of Ambergris.

Key Points

  • About:
    • Ambergris, French for grey amber, is generally referred to as whale vomit.
    • It is a solid waxy substance originating in the intestine of the sperm whale.
      • Ambergris is produced only by an estimated 1% of sperm whales.
    • Chemically, ambergris contains alkaloids, acids, and a specific compound called ambreine, which is similar to cholesterol.
    • It floats around the surface of the water body and at times settles on the coast.
    • Because of its high value it is referred to as floating gold. 1 kg of ambergris is worth Rs 1 crore in the international market.
  • Use:
    • It is used in the perfume market, especially to create fragrances like musk.
      • It is believed to be in high demand in countries like Dubai that have a large perfume market.
    • Ancient Egyptians used it as incense. It is also believed to be used in some traditional medicines and as a spice.
  • Smuggling:
    • Due to its high value it has been a target for smugglers especially in coastal areas.
      • There have been several cases where the coastline of Gujarat has been used for such smuggling.
    • Since the sperm whale is a protected species, hunting of the whale is not allowed. However, smugglers are known to have illegally targeted the fish in order to obtain the valuable Ambergris from its stomach.

Sperm Whale

  • About:
    • Sperm whale, (Physeter catodon), also called cachalot, the largest of the toothed whales, easily recognized by its enormous square head and narrow lower jaw.
    • The sperm whale is dark blue-gray or brownish, with white patches on the belly. It is thickset and has small paddle-like flippers and a series of rounded humps on its back.
  • Habitat:
    • They are found in temperate and tropical waters throughout the world.
  • Threats:
    • The greatest threats to sperm whales are those of habitat impacts including noise pollution and climate change.
    • Other threats include entanglement in fishing gear, collisions with ships, and proposals to allow for a commercial hunt once again.
  • Protection Status:

LiDAR Based Survey of Forest Areas

Why in News

Recently, the Union Environment Minister in a virtual event released the Detailed Project Reports (DPRs) of LiDAR (Light Detection and Ranging) based survey of forest areas in ten states.

  • The 10 mapped states are Assam, Bihar, Chhattisgarh, Goa, Jharkhand, Madhya Pradesh, Maharashtra, Manipur, Nagaland, and Tripura.

Key Points

  • Survey of Forest Areas Project:
    • The project was awarded to WAPCOS in July 2020 at a cost of over Rs. 18 crore for implementation in 26 states over 261897 hectares.
      • WAPCOS is a Mini Ratna Public Sector Undertaking (PSU) under the Jal Shakti Ministry.
    • It is a first of its kind and a unique experiment using LiDAR technology which will help augment water and fodder in jungle areas thereby reducing human-animal conflict.
      • LiDAR technology has been found to have 90% accuracy.
    • States will be given Compensatory Afforestation Fund Management and Planning Authority (CAMPA) funds to use in this project.
      • CAMPA is meant to promote afforestation and regeneration activities as a way of compensating for forest land diverted to non-forest uses.
      • CAMPA was established to manage the Compensatory Afforestation Fund (CAF) and it acts as the custodian of the CAMPA fund.
    • One major ridge inside a forest block is identified in these states with an average area of 10,000 ha selected in each State; the area should have average rainfall of the state, and requires assisted natural generation.
  • Significance:
    • Besides reducing human-animal conflict, it will help us in identifying areas which need groundwater recharge which will in turn help local communities.
    • It will help in catching rainwater and prevent stream run-off, which will help in recharging groundwater.
    • It will help in recommending different types of Soil & Water conservation structures such as Anicut, Gabion, Gully Plug, Mini percolation tank, Percolation Tank, Field bund, Sunken pond, Farm pond etc.

LiDAR

  • About:
    • It is a remote sensing method that uses light in the form of a pulsed laser to measure ranges & variable distances.
    • These light pulses—combined with other data recorded by the airborne system— generate precise, three-dimensional information about the shape of the Earth and its surface characteristics.
    • A LiDAR instrument principally consists of a laser, a scanner, and a specialized Global Positioning System (GPS) receiver.
      • Airplanes and helicopters are the most commonly used platforms for acquiring LiDAR data over broad areas.
    • LiDAR follows a simple principle — throw laser light at an object on the earth surface and calculate the time it takes to return to the LiDAR source.
      • Given the speed at which the light travels (approximately 186,000 miles per second), the process of measuring the exact distance through LiDAR appears to be incredibly fast.
  • Applications:
    • Lidar is commonly used to make high-resolution maps, with applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping (ALSM), and laser altimetry.

INS Vikrant: First Indigenous Aircraft Carrier

Why in News

Recently, India’s Defence Minister reviewed the ongoing work on the Indigenous Aircraft Carrier (IAC), INS Vikrant (IAC-1), which is a part of Atmanirbhar Bharat.

Key Points

  • About:
    • The vessel, to be named Vikrant after the decommissioned maiden carrier of the Navy.
    • It will have an air component of 30 aircraft, comprising MiG-29K fighter jets, Kamov-31 airborne early warning helicopters and the soon-to-be-inducted MH-60R multi-role helicopter, besides the indigenous Advanced Light Helicopters.
    • It is expected to have a top speed of 30 knots (approximately 55 kmph) and is propelled by four gas turbines. Its endurance is 7,500 nautical miles at 18 knots (32 kmph) speed.
    • The shipborne weapons include Barak LR SAM and AK-630, while it has MFSTAR and RAN-40L 3D radars as sensors. The vessel has a Shakti EW (Electronic Warfare) Suite.
    • It has a pair of runways and a ‘short take off but arrested recovery’ system to control aircraft operations.
  • Significance:
    • The combat capability, reach and versatility of the aircraft carrier will add formidable capabilities in the defence in the country and help secure India's interests in the maritime domain.
    • It would offer an incomparable military instrument with its ability to project air power over long distances, including air interdiction, anti-surface warfare, offensive and defensive counter-air, airborne anti-submarine warfare and airborne early warning.
  • Current Status of Indian Navy:
    • As per the Maritime Capability Perspective Plan, by 2027, India ought to have about 200 ships but there is still a lot to cover to reach the target.
      • However, the cause is not mainly funding but procedural delays or some self imposed restrictions.
    • The navy ensures that it has state of the art SONARs and Radars. Also, many of the ships contain a high amount of indigenous content.
  • Navy’s Contribution to Fight against Covid-19:
