  • Degradation of Aravalis

    The Supreme Court has ordered the Haryana government to take “all essential measures” to remove encroachments, including some residential constructions, in the ecologically fragile Aravali forest land near a village.

    Aravali Range

    • The Aravali is a mountain range in Northwestern India, running approximately 670 km in a southwest direction, starting near Delhi, passing through southern Haryana and Rajasthan, and ending in Gujarat.
    • The highest peak is Guru Shikhar at 1,722 meters.
    • The Aravalli Range, an eroded stub of ancient mountains, is the oldest range of fold mountains in India.
    • The natural history of the Aravalli Range dates back to times when the Indian Plate was separated from the Eurasian Plate by an ocean.
    • Three major rivers and their tributaries flow from the Aravalli, namely Banas and Sahibi rivers which are tributaries of Yamuna, as well as Luni River which flows into the Rann of Kutch.
    • The Sariska-Delhi leopard wildlife corridor is a 200 km long important biodiversity and wildlife corridor which runs from the Sariska Tiger Reserve in Rajasthan to Delhi Ridge.

    Threats to its existence

    • Ecological degradation in the Aravalli region is in an alarming situation.
    • This is due to the increasing population of humans and cattle, injudicious use of natural resources, unscientific mining, uncontrolled grazing, and felling of trees.

  • [pib] Sustainable Public Procurement (SPP)

    On the occasion of World Environment Day, a new product category of Green Room Air Conditioners was launched on the Government e-Marketplace (GeM) under the Sustainable Public Procurement (SPP) program.

    What is Sustainable Public Procurement (SPP)?

    • SPP is a process by which public authorities seek to achieve the appropriate balance between the three pillars of sustainable development – economic, social and environmental – when procuring goods, services or works at all stages of the project.
    • These three pillars are called Triple Bottom Line.
    • The UN Environment Programme (UNEP) has been active in the promotion of Sustainable Public Procurement at national, regional and global levels since 2005.

    Why need SPP?

    • Public procurement spend in India is nearly 15-20% of its GDP.
    • Introducing SPP to this huge quantum of government procurement will further complement the country’s climate policy objectives.
    • This innovation can provide financial savings for government buyers and will meet evolving environmental challenges by moving towards a circular economy.

    Back2Basics: Government E-Marketplace

    • The GeM is a one-stop National Public Procurement Portal to facilitate online procurement of common use Goods & Services required by various Government Departments / Organizations / PSUs.
    • It was launched in 2016 to bring transparency and efficiency in the government buying process.
    • GEM aims to enhance transparency, efficiency and speed in public procurement.
    • It is a completely paperless, cashless and system driven e-marketplace that enables procurement of common use goods and services with minimal human interface.
    • It provides the tools of e-bidding, reverse e-auction and demand aggregation to facilitate the government users to achieve the best value for their money.
    • The purchases through GeM by Government users have been authorized and made mandatory by the Ministry of Finance by adding a new Rule No. 149 in the General Financial Rules, 2017.
    • It has been developed by Directorate General of Supplies and Disposals (Ministry of Commerce and Industry) with technical support of National e-governance Division (MEITy).

  • ‘Sea Snot’ outbreak in Turkey

    There has been growing environmental concern in Turkey over the accumulation of ‘sea snot’, a slimy layer of grey or green sludge in the country’s seas, which can cause considerable damage to the marine ecosystem.

    What is ‘Sea Snot’?

    • ‘Sea snot’ is marine mucilage that is formed when algae are overloaded with nutrients as a result of water pollution combined with the effects of climate change.
    • A ‘sea snot’ outbreak was first recorded in the country in 2007. Back then, it was also spotted in the Aegean Sea near Greece.
    • But the current outbreak in the Sea of Marmara is by far the biggest in the country’s history.
    • The nutrient overload occurs when algae feast on warm weather caused by global warming. Water pollution adds to the problem.
    • Environmental experts have said that the overproduction of phytoplankton caused by climate change and the uncontrolled dumping of household and industrial waste into the seas has led to the present crisis.

    Where has it been found?

    • Turkey’s Sea of Marmara, which connects the Black Sea to the Aegean Sea, has witnessed the largest outbreak of ‘sea snot’.
    • The sludge has also been spotted in the adjoining Black and Aegean seas.

    How badly can the crisis affect the marine ecosystem?

    • The growth of the mucilage, which floats upon the surface of the sea like brown phlegm, is posing a severe threat to the marine ecosystem of the country.
    • Divers have said that it has caused mass deaths among the fish population, and also killed other aquatic organisms such as corals and sponges.
    • The mucilage is now covering the surface of the sea and has also spread to 80-100 feet below the surface.
    • If unchecked, this can collapse to the bottom and cover the sea floor, causing major damage to the marine ecosystem.
    • Over a period of time, it could end up poisoning all aquatic life, including fishes, crabs, oysters, mussels and sea stars.

  • [pib] SDG India Index 2021

    The third edition of the SDG India Index and Dashboard 2020–21 was released by NITI Aayog.

    SDG India Index

    • The index measures the progress at the national and sub-national level in the country’s journey towards meeting the Global Goals and targets.
    • It has been successful as an advocacy tool to propagate the messages of sustainability, resilience, and partnerships, as well.
    • From covering 13 Goals, 39 targets, and 62 indicators in the first edition in 2018-19 to 17 Goals, 54 targets and 100 indicators in the second; this third edition of the index covers 17 Goals, 70 targets, and 115 indicators.

    Aims and objectives

    • The construction of the index and the ensuing methodology embodies the central objectives of measuring the performance of States and UTs on the SDGs and ranking them.
    • It aims at supporting States and UTs in identifying areas which require more attention; and promoting healthy competition among them.

    Methodology and Process

    • The index estimation is based on data on indicators for the first 16 goals, with a qualitative assessment for Goal 17.
    • The technical process of target setting and normalization of scores follow the globally established methodology.
    • While target setting enables the measurement of the distance from the target for each indicator, the process of normalization of positive and negative indicators allows for comparability and estimation of goal-wise scores.
    • The composite score of a State is derived by assigning each goal the same weight, keeping in mind the indivisible nature of the 2030 Agenda.
    • The selection of indicators is preceded by a consultative process undertaken in close coordination with MoSPI, Union Ministries and stakeholders from States and UTs.

    Highlights of the 2021 Report

    States and Union Territories are classified as below based on their SDG India Index score:

    • Aspirant: 0–49
    • Performer: 50–64
    • Front-Runner: 65–99
    • Achiever: 100

    Its significance

    • The index represents the articulation of the comprehensive nature of the Global Goals under the 2030 Agenda while being attuned to the national priorities.
    • The modular nature of the index has become a policy tool and a ready reckoner for gauging the progress of States and UTs on the nature of goals including health, education, gender, economic growth and climate change and the environment.

    Back2Basics: Sustainable Development Goals

    • The UN General Assembly in its 70thSession considered and adopted the Sustainable Development Goals (SDGs) for the next 15 years.
    • The 17 SDGs came into force with effect from 1st January 2016.
    • Though not legally binding, the SDGs have become de facto international obligations and have the potential to reorient domestic spending priorities of the countries during the next fifteen years.
    • Countries are expected to take ownership and establish a national framework for achieving these goals.
    • Implementation and success will rely on countries’ own sustainable development policies, plans, and programs.

  • International Nitrogen Initiative (INI)

    The United Nations (UN) Sustainable Development Goals (SDGs) are the main focus of the eighth triennial conference of the International Nitrogen Initiative (INI) being held virtually this week.

    International Nitrogen Initiative

    • INI is an international program, set up in 2003 under the sponsorship of the Scientific Committee on Problems of the Environment (SCOPE) and from the International Geosphere-Biosphere Program (IGBP).
    • The key aims of the INI are to:
    1. optimize nitrogen’s beneficial role in sustainable food production, and
    2. minimize nitrogen’s negative effects on human health and the environment resulting from food and energy production.

    Answer this PYQ in the comment box:

    Q.Which of the following adds/add nitrogen to the soil?

    1. Excretion of Urea by animals
    2. Burning of coal by man
    3. Death of vegetation

    [Burning Issue] Nitrogen Pollution in India

    Back2Basics: Nitrogen Pollution

    • While nitrogen is the dominant gas in the atmosphere, it is inert and doesn’t react.
    • However, when it is released as part of compounds from agriculture, sewage and biological waste, nitrogen is considered reactive.
    • It may be polluting and even exert a potent greenhouse gas effect.
    • Nitrous oxide (N2O) is 300 times more potent than carbon dioxide but isn’t as prevalent in the atmosphere.
    • Other than air pollution, nitrogen is also linked to the loss of biodiversity, the pollution of rivers and seas, ozone depletion, health, economy, and livelihoods.
    • Nitrogen pollution is caused, for example, by emissions from chemical fertilizers, livestock manure and burning fossil fuels.
    • Gases such as ammonia (NH3) and nitrogen dioxide (NO2) contribute to poor air quality and can aggravate respiratory and heart conditions, leading to millions of premature deaths across the world.
    • Nitrate from chemical fertilizers, manure, and industry pollute the rivers and seas, posing a health risk for humans, fish, coral, and plant life.

  • Species in news: Litoria Mira

    A species of frog lives in the rainforests of New Guinea that appears to be made from chocolate — just like the magical sweets popular in the wizarding world of J K Rowling’s Harry Potter.

    Litoria mira

    • The cocoa-colored frogs have turned out to be a new species — and an addition to our knowledge of the animal kingdom.
    • It has a well-known relative — the common green tree frog of Australia called Litoria cerulean.
    • Litoria Mira can be distinguished from all other Litoria by its unique combination of moderately large size, webbing on hand, relatively short and robust limbs, and a small violet patch of skin on the edge of its eyes.

  • Why people are Protesting in Lakshadweep

    The article highlights the issues with development model sought to be pursued in Lakshadweep.

    Background of Island Development Authority’

    • A specially constituted Island Development Authority (IDA) for the island territories of India, chaired by no less than the former Prime Minister, Rajiv Gandhi.
    • IDA had in 1988, approved a framework for the development of India’s island territories.
    • IDA sought an environmentally sound strategy for both island groups hinges on better exploitation of marine resources coupled with much greater care in the use of land resources.
    • Deliberations of the IDA wanted that Lakshadweep, with its land ownership constitutionally protected, be opened to international tourism.

    Issues with following Maldives model for development of Lakshadweep

    •  Recently, the Administrator, Lakshadweep, introduced a slew of draft legislation that will have a wide-ranging impact on the islands.
    • One such legislation is the Lakshadweep Development Authority Regulation 2021 with intentions to develop Lakshadweep like neighbouring Maldives, “a renowned international tourist destination”.
    • Rejecting the Maldives model, the plan for Lakshadweep required that the industry had to be people-centric and enrich the fragile coral ecology.
    • Today, long lines and refrigeration have aided the expansion of the fishing sector but income disparities have grown.
    • Indiscriminate trawling endangers the coral, as experienced in the Maldives and now banned there.
    • The Government recognises the need to develop policies for enhancing employment opportunities, environment-friendly management of fisheries, sanitation, waste disposal and widening access to drinking water, with the youth, having acquired a modern education, preferring salaried jobs over pursuing traditional occupations.

    Conclusion

    What Lakshadweep needs is a clear policy must include conservation and natural resource management arrived at after wide consultation, eminently possible within the existing infrastructure of the Union Territory, and also taking into account climatic compulsions.

  • Cost and complications of transplanting a tree

    The Central Public Works Department (CPWD) wants to transplant over 1,800 trees which are inside what used to be the Indira Gandhi National Centre for the Arts (IGNCA) complex, as part of the Central Vista redevelopment project.

    Transplantation of trees

    • The transplantation of trees is a complex and delicate process whose outcome cannot be predicted.
    • A tree cannot be transplanted by simply uprooting it and placing it in a pit dug elsewhere. The process involves multiple steps and requires significant expertise.

    How it is done?

    • First, the soil around the tree is dug up to isolate the roots. The big branches are lopped off, leaving only small shoots for regeneration. This is done to make transportation of the tree to the new location easier.
    • The root system is covered with wet gunny bags to protect the roots and to keep the tree hydrated.
    • The tree has to be first sent to a nursery to acclimatize to a new kind of soil, and to regenerate.
    • Once new shoots start sprouting, the tree is lowered into a pit created in its new spot.

    What factors determine the success of a transplant?

    • Even after all steps are meticulously followed, a lot depends on luck. The survival rate of a transplanted tree is about 50%.
    • Not all trees can be transplanted. While peepal, ficus, semal and sheesham are tolerant to transplantation, trees such as dak, palash, arjun, shahtoot and jhilmil are not.

    (1) Roots

    • Any tree that has a tap root system cannot be transplanted, as the root goes deep into the soil, and it is not possible to isolate it without damage.

    (2) Size

    • Transplanting any tree with a trunk girth of more than 80-90 cm is not advisable as the tree cannot bear the shock, and will eventually die.

    (3) Age

    • That effectively means that big, old trees cannot, in most cases, be removed to another location.

    (4) Soil

    • It is important to consider soil type before transplantation.
    • A tree growing on, say, the Delhi Ridge will not easily acclimatize to the soil in the Yamuna floodplain, as the two ecosystems are entirely different.

    How expensive is transplantation?

    • The cost of transplanting an average-sized tree might come to around Rs 1 lakh, which included post-transplantation care.
    • For larger trees, the cost could go up to Rs 3 lakh.
    • Private and voluntary organizations, however, claim that the cost is between Rs 5,000 and Rs 10,000 per tree.

  • Odisha’s blackbucks double in 6 years

    Odisha’s blackbuck population has doubled in the last six years, according to figures from the latest population census.

    Blackbucks in Odisha

    • Blackbucks are found only in the Ganjam district in the southern part of the state, which is where the census was carried out.
    • It is known in Odisha and Ganjam as Krushnasara Mruga.
    • The people of Ganjam believe the sighting of a blackbuck in a paddy field is a harbinger of luck for them.
    • It used to be sighted in the Balukhand-Konark Wildlife Sanctuary in Puri district till 2012-13, but now has vanished from the area.
    • The blackbuck is a Schedule-1 animal according to the Wild Life (Protection) Act, 1972 (amended in 1992) and is considered as ‘Vulnerable’ according to the Red Data Book.

    Reasons for their rise

    • Improvement of habitats, the protection given by the local people and forest staff were some of the reasons for the increase of the population.
    • The people of Ganjam had been enthusiastically protecting the animal like the Bishnois of western Rajasthan and the Vala Rajputs of Saurashtra.

    Back2Basics: Wildlife (Protection) Act, 1972

    • WPA provides for the protection of the country’s wild animals, birds, and plant species, in order to ensure environmental and ecological security.
    • It provides for the protection of a listed species of animals, birds, and plants, and also for the establishment of a network of ecologically important protected areas in the country.
    • It provides for various types of protected areas such as Wildlife Sanctuaries, National Parks, etc.
    • There are six schedules provided in the WPA for the protection of wildlife species which can be concisely summarized as under:
    Schedule I: These species need rigorous protection and therefore, the harshest penalties for violation of the law are for species under this Schedule.
    Schedule II: Animals under this list are accorded high protection. They cannot be hunted except under threat to human life.
    Schedule III & IV: This list is for species that are not endangered. This includes protected species but the penalty for any violation is less compared to the first two schedules.
    Schedule V: This schedule contains animals which can be hunted.
    Schedule VI: This list contains plants that are forbidden from cultivation.

     

  • NGT upholds rights of pastoralists in Banni Grasslands

    The National Green Tribunal (NGT) ordered all encroachments to be removed from Gujarat’s Banni grasslands.

    Banni Grasslands
