  • [pib] Nationally Determined Contributions (NDC) Transport Initiative for Asia (TIA)

    NITI Aayog will virtually launch the India Component of the Nationally Determined Contributions (NDC)–Transport Initiative for Asia (TIA).

    Try this PYQ:

    Q.The term Intended Nationally Determined Contribution is sometimes seen in the news in the context of:

    (a) Pledge made by the European countries to rehabilitate refuges from the war-affected Middle East.

    (b) Plan of nation outlined by the countries of the world to combat climate changes.

    (c) Capital contributed by the member countries in the establishment of Asian Infrastructure Investment Bank.

    (d) Plain of action outlined by the countries of the regarding SDGs.

    What is NDC-TIA?

    • It is a joint programme, supported by the International Climate Initiative (IKI) of the German Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU).
    • On behalf of the GoI, NITI Aayog will be the implementing partner.
    • It aims to promote a comprehensive approach to decarbonize transport in India, Vietnam, and China.
    • It is implemented by a consortium of seven other organisations.

    Working

    • The programme has a duration of 4 years.
    • The India Component will focus on establishing a multi-stakeholder dialogue platform for decarbonizing transport in India, strengthening GHG and transport modelling capacities.
    • It would help in financing climate actions in transport, offering policy recommendations on electric vehicle (EV) demand and supply policies.

    Why need TIA?

    • India has a massive and diverse transport sector that caters to the needs of billion people.
    • It has the world’s second-largest road network, which contributes to maximum GHG emissions through all means of transportation.
    • With increasing urbanisation, the fleet size i.e. the number of sales of vehicles is increasing rapidly.
    • It is projected that the total number of vehicles will be doubled by 2030.

  • What is Biochar?

    A new research has shown that Biochar application is more effective in promoting pulses growth and yield in Ghana.

    Try this PYQ:

     

    Q.In the context of which one of the following are the terms ‘pyrolysis and plasma gasification’ mentioned? (CSP 2019)

    (a) Extraction of rare earth elements

    (b) Natural gas extraction technologies

    (c) Hydrogen fuel-based automobiles

    (d) Waste-to-energy technologies

    What is Biochar?

    • Biochar is a high-carbon, fine-grained residue that is currently produced through modern pyrolysis processes (direct thermal decomposition of biomass in the absence of oxygen and preventing combustion).
    • It produces a mixture of solids (the biochar proper), liquid (bio-oil), and gas (syngas) products.
    • Biochar may increase soil fertility of acidic soils (low pH soils), increase agricultural productivity, and provide protection against some foliar and soil-borne diseases.

    Its benefits

    • Carbon Sink: The burning and natural decomposition of biomass releases large amounts of carbon dioxide and methane to the Earth’s atmosphere. The biochar production process also releases CO2 (up to 50% of the biomass); however the remaining carbon content is stable indefinitely.
    • Soil Amendment: Biochar is recognized as offering a number of soil health benefits. The extremely porous nature of biochar is found to be effective at retaining both water and water-soluble nutrients. Its presence in the earth can improve water quality, increase soil fertility, raise agricultural productivity, and reduce pressure on old-growth forests.
    • Water retention: Biochar is hygroscopic. Thus it is a desirable soil material in many locations due to its ability to attract and retain water.

    Back2Basics

    What is Pyrolysis?

    • Pyrolysis is the thermal decomposition of materials at elevated temperatures in an inert atmosphere.
    • It involves a change in chemical composition. The word is coined from the Greek-derived elements pyro “fire” and lysis “separating”.
    • It is most commonly used in the treatment of organic materials. It is one of the processes involved in charring wood.
    • It is considered as the first step in the processes of gasification or combustion.

    How does it work?

    • In general, pyrolysis of organic substances produces volatile products and leaves a solid residue enriched in carbon, char.
    • Extreme pyrolysis, which leaves mostly carbon as the residue, is called carbonization.
    • The process is used heavily in the chemical industry, for example, to produce ethylene, many forms of carbon, and other chemicals from petroleum, coal, and even wood, to produce coke from coal.

  • BIS’ draft standard for drinking water supply

    The Bureau of Indian Standards (BIS) has prepared a draft standard for the supply system of piped drinking water.

    Try this question for mains:

    Q.Climate change, scarcity, population growth, demographic changes and urbanization pose challenges for water supply systems in India. Analyse.

    About the Draft

    • Labelled ‘Drinking water supply quality management system — requirements for piped drinking water supply service’, the draft has been prepared by the BIS’ Public Drinking Water Supply Services Sectional Committee.
    • It outlines the process of water supply, from raw water sources to household taps.
    • It has been developed keeping in view the Centre’s Jal Jeevan Mission for providing safe and adequate drinking water to all rural households by 2024 through tap connections.
    • It is expected to make the process of piped water supply more uniform, especially in rural and underdeveloped areas of the country where the system runs on various government orders and circulars.
    • At present, the standard is expected not to be made mandatory.

    Highlights of the draft

    • The draft outlines the requirements for a water supplier or a water utility on how they should establish, operate, maintain and improve their piped drinking water supply service.
    • The process begins with the identification of a water source, which can either be groundwater or surface water sources such as rivers, streams or reservoirs.
    • It doesn’t mention how water utilities should treat the water, but states that the process should be planned in such a manner that after treatment it should conform to the Indian Standard (IS) 10500 developed by the BIS.
    • The IS 10500 outlines the acceptable limits of heavy metals such as arsenic, and other parameters like the pH value of water, its turbidity, the total dissolved solids in it, and the colour and odour.

    What is the water supply process?

    • The supply system as outlined in the draft should begin with the identification of a raw water source.
    • Water should then be pumped into the treatment plant and treated to achieve acceptable drinking standards.
    • After the water is released from the plant, there should be reservoirs in the distribution system for storage of this water, and disinfection facilities to get rid of contamination at any stage of distribution.
    • Pumping stations or boosters, if necessary, should be provided to maintain adequate pressure throughout the distribution system.

    District Metering Area (DMA) concept

    • The document also states that the concept of district metering area (DMA) should be adopted where possible.
    • DMA is a concept for controlling leakages in the water network, which is essentially divided into a number of sectors, called the DMAs, and where flow meters are installed to detect leaks.
    • The water supplier/utility may provide bulk water meters in the water distribution system to ensure water audit, however, the provisions should be made for domestic meters also.

    What’s there in the draft in addition to the water supply process?

    • There are guidelines on water audit, which is a calculation of the amount of water put into distribution against the amount that is consumed.
    • The draft states that a water audit should be conducted on a quarterly basis.
    • Effort should be made by the water agency to bring down the water loss up to 15% of the total water supplied in the system.
    • The water utilities are also required to conduct surveys among consumers and obtain feedback on their service as per the draft.
    • Guidelines on internal audit, management review, documenting performance indicators for improvement, and timely action against non-conformity issues also find mention.

  • Gorumara National Park

    A bison (Indian Gaur) was allegedly poached in Gorumara National Park.

    Try this PYQ:

    Which one of the following National Parks lies completely in the temperate alpine zone?(CSP 2019)

    (a) Manas National Park

    (b) Namdapha National Park

    (c) Neora Valley National Park

    (d) Valley of Flowers National Park

    Gorumara NP

    • It is located in the Eastern Himalayas’ submontane Terai belt.
    • This region has rolling forests and riverine grasslands, and is known as the Dooars in West Bengal.
    • The park is located on the flood plains of the Murti River and Raidak River. The major river of the park is the Jaldhaka river, a tributary of the Brahmaputra river system.
    • In this regard, Gorumara is a significant watershed area between the Ganges and Brahmaputra river systems.
    • The park is rich in large herbivores including Indian rhinoceros, gaur, Asian elephant, sloth bear, chital, and sambar deer. Small herbivores include barking deer, hog deer and wild boar.

    About Gaur

    • The Gaur called the Indian bison, is native to South and Southeast Asia and has been listed as Vulnerable on the IUCN Red List since 1986.
    • It is the largest species among the wild cattle.
    • The domesticated form of the gaur is called gayal (Bos frontalis) or mithun.

  • Micro-plastic Pollution in Atlantic Ocean

    The Atlantic Ocean contains 12-21 million tonnes of microplastics — about 10 times higher than previously determined — according to new research published in Nature Communications.

    Highlights of the report

    • In the study, scientists studied pollution of the Atlantic Ocean caused by three types of plastics: polyethylene, polypropylene, and polystyrene, which were suspended in the top 200 metres of the ocean.
    • These three types of plastic are most commonly used for packaging.
    • Scientists say that pollution caused by microplastics has been “severely” underestimated in previous assessments.
    • They also estimate that based on plastic waste generation trends from 1950-2015 and considering that the Atlantic Ocean has received 0.3-0.8 per cent of the global plastic waste for 65 years.
    • To date, a key uncertainty has been the magnitude of contamination of the ocean and our findings demonstrate that this is much higher in terms of mass than has been estimated previously.

    Try this PYQ:

    Q. Why is there a great concern about the ‘microbeads’ that are released into the environment? (CSP 2019)

    (a) They are considered harmful to marine ecosystems.

    (b) They are considered to cause skin cancer in children.

    (c) They are small enough to be absorbed by crop plants in irrigated fields.

    (d) They are often found to be used as food adulterants.

    What are Microplastics?

    • Microplastics are plastic debris smaller than 5mm in length, or about the size of a sesame seed.
    • While they come from a variety of sources, one of them is when larger pieces of plastic degrade into smaller pieces, which are difficult to detect.

    How does plastic reach the oceans?

    • There are multiple pathways for them to reach the oceans.
    • For instance, riverine and atmospheric transport from coastal and inland areas, illegal dumping activities and direct-at-sea littering from shipping, fishing and aquaculture activities, scientists have said.
    • According to the IUCN, at least 8 million tonnes of plastic end up in the oceans every year and makes up about 80 per cent of all marine debris from surface waters to deep-sea sediments.

    Why is plastic pollution especially harmful?

    • Plastic can take hundreds to thousands of years to decompose depending on the type of plastic and where it has been dumped.
    • Some marine species such as zooplanktons show preferential ingestion of smaller particles, making them easier to enter the food chain and their conversion to fast-sinking faecal pellets.
    • Over the past few years, various news reports have shown that marine animals such as whales, seabirds and turtles unknowingly ingest plastic and often suffocate to death.
    • While all sorts of marine species are prone to get impacted by plastic pollution, typically, bigger marine species tend to get more attention because of the amounts of debris they can hold up.

    Impact on humans

    • For humans, too, marine plastic pollution is harmful if it reaches the food chain. For instance, microplastics have been found in tap water, beer and even salt.
    • One of the first studies to estimate plastic pollution in human ingestion that was published in June 2019 said that an average person eats at least 50,000 particles of microplastic each year.
    • Consumption of plastic by humans is harmful since several chemicals that are used to produce plastics can be carcinogenic.
    • Even so, since microplastics are an emerging field of study, its exact risks on the environment and human health are not clearly known.

  • Bioethanol Blending in Petrol

    The government has set targets of 10 per cent bioethanol blending of petrol by 2022 and to raise it to 20 per cent by 2030 to curb carbon emissions and reduce India’s dependence on imported crude oil.

    Try this PYQ:

    Q.Given below are the names of four energy crops. Which one of them can be cultivated for ethanol?(CSP 2010)

    (a) Jatropha

    (b) Maize

    (c) Pongamia

    (d) Sunflower

    What is Ethanol Blended Petrol (EBP) Program?

    • Ethanol Blended Petrol (EBP) programme was launched in January 2003 for the supply of 5% ethanol blended petrol.
    • The programme sought to promote the use of alternative and environment-friendly fuels and to reduce import dependency for energy requirements.
    • OMCs are advised to continue according to the priority of ethanol from 1) sugarcane juice/sugar/sugar syrup, 2) B-heavy molasses 3) C-heavy molasses and 4) damaged food grains/other sources.

    Bio-ethanol blend in India

    • 1G and 2G bioethanol plants are set to play a key role in making bio-ethanol available for blending but face challenges in attracting investments from the private sector.
    • 1G bioethanol plants utilise sugarcane juice and molasses, byproducts in the production of sugar, as raw material, while 2G plants utilise surplus biomass and agricultural waste to produce bioethanol.
    • Currently, domestic production of bioethanol is not sufficient to meet the demand for bio-ethanol for blending with petrol at Indian Oil Marketing Companies (OMCs).
    • Sugar mills, which are the key domestic suppliers of bio-ethanol to OMCs, were only able to supply 1.9 billion litres of bio-ethanol to OMCs equating to 57.6 per cent of the total demand of 3.3 billion litres.

    Hurdles in meeting the demand

    • Lack of infrastructure: Many sugar mills are best placed to produce bioethanol do not have the financial stability to invest in biofuel plants. There are also concerns among investors on the uncertainty over the price of bio-ethanol in the future.
    • Lack of raw materials: Presently there is no mechanism for depots where farmers could drop their agricultural waste. The central government should fix a price for agricultural waste to make investments in 2G bioethanol production an attractive proposition.
    • Rigid pricing mechanism: Sugars mills have to pay high prices for sugarcane set by the government even when there have been supplying gluts. The prices of both sugarcane and bio-ethanol are set by the central government.

    Way ahead

    • The government should provide greater visibility on the price of bioethanol that sugar mills can expect by announcing a mechanism by which the price of bio-ethanol would be decided.
    • 2G bioethanol not only provided a clean source of energy but also help provide greater income to farmers and prevent them from having to burn agricultural waste which can be a major source of air pollution.

  • Bhadbhut Project

    The Gujarat government recently awarded the contract for a the Bhadbhut project in Bharuch, Gujarat. It has faced protests from local fishermen for its likely impact on fishing patterns, notably those of hilsa.

    Make a note of major dams in India along with the rivers, terrain, major wildlife sanctuaries and national parks incident to these rivers.

    What is the Bhadbhut Project?

    • It is planned to be a 1.7-km causeway-cum-weir barrage with 90 gates, across the river Narmada, 5 km from Bhadbhut village, and 25 km from the mouth of the river, where it flows into the Gulf of Khambhat.
    • The barrage will stop most of the excess water flowing out of the Sardar Sarovar Dam from reaching the sea and thus create a “sweet water lake” of 600 mcm (million cubic metres) on the river.
    • The barrage will also have a six-lane road that will connect the left and right banks of the river and provide shorten the land distance between two large industrial estates in Surat and Bharuch.
    • The project also aims to prevent flooding in years when rainfall is higher than normal.
    • Embankments 22 km long will be made and will extend upstream towards Bharuch, from either side of the river.
    • The project is part of the larger Kalpasar Project, which entails the construction of a 30-km dam across the Gulf of Khambhat between Bharuch and Bhavnagar districts.
    • The reservoir is meant to tap the waters of the Narmada, Mahisagar and Sabarmati.

    Why are fishermen upset?

    • The barrage is expected to interfere with the migration and breeding cycle of hilsa.
    • A marine fish, hilsa migrate upstream and arrives in the brackish water of the Narmada estuary near Bharuch for spawning usually during the monsoon months of July and August, and continue doing so till November.
    • Once the barrage is built, it is expected to block its natural entry.

    About Hilsa Fish

    IUCN status: Least Concerned

    • The Hilsa is a species of fish related to the herring, in the family Clupeidae.
    • It is a very popular and sought-after food fish in the Indian Subcontinent.
    • Though it’s a saltwater fish, it migrates to sweet waters.
    • It is the national fish of Bangladesh and state symbol in the Indian states of West Bengal and Tripura.
    • The fish contributes about 12% of the total fish production and about 1.15% of GDP in Bangladesh.

  • Myth of the pristine forest

    • The COVID-19 pandemic has driven migrant workers back to their villages, including many situated inside or on the fringes of forested areas, including sanctuaries and national parks.
    • Even as they seek to remake livelihoods there, a new battle has emerged between the forest department (FD) and these local communities.
    • It pertains to the declaration of a Critical Wildlife Habitat (CWH), which a PIL in the Bombay High Court seeks to get the department to urgently notify.

    Try this question for mains:

    Forest dwellers are integral to the very survival and sustainability of the forest ecosystem. Analyse.

    What is Critical Wildlife Habitat (CHW)?

    • CWH is a provision under the Forest Rights Act, 2006 (FRA).
    • The Act primarily focuses on recognising the historically-denied rights of forest-dwellers to use and manage forests.
    • The CWH provision, however, is an attempt to assuage concerns of wildlife conservationists.
    • It allows for the possibility that in protected areas (PAs) — wildlife sanctuaries and national parks — these rights could be attenuated, and, if absolutely necessary, forest-dwellers could be relocated in the interest of wildlife conservation.

    Forest dwellers vs. Wildlife

    • Conservationists believe that wildlife needs absolutely “inviolate” areas — those devoid of humans and human activities.
    • Many others believe human-wildlife co-existence is generally possible and must be promoted if we are to have “socially just conservation”.

    Achieving balanced conservation: The FRA provisions

    • A careful reading of the CWH provisions in the FRA shows that it is open to both possibilities, as long as they are arrived at through a rigorous and participatory process.
    • It requires setting up a multi-disciplinary expert committee, including representatives from local communities.
    • It also requires determining — using “scientific and objective criteria” and consultative processes — whether, and wherein the PA, the exercise of forest rights will cause irreversible damages.
    • It then requires determining whether coexistence is possible through a modified set of rights or management practices.
    • Only if the multi-stakeholder expert committee agrees that co-existence or other reasonable options are not possible, should relocation be taken up, again with the informed consent of the concerned gram sabhas.
    • For any such process to commence, the Act requires that all forest rights under the FRA must first be recognised.

    Issues with the FRA

    (1) Concerns of eviction

    • Hardline conservationists took FRA as a great opportunity to complete its agenda of evicting forest-dwellers from PAs.
    • It has been observed that many villages were resettled when they had rights claims pending, others had their claims illegally rejected or incompletely granted, and several had not even applied to this controversy erupted.
    • However, there are settlements in some of these PAs, and of course, people in villages adjacent to all the PAs are likely to have customary rights.
    • In spite of the court ordering rapid completion of the rights recognition process, there has been almost no progress on this front.

    (2) Issues with expert committees

    • The constitution of the expert committees is faulty. They do not contain expert social scientists familiar with the area. Wildlife enthusiasts are sometimes substituted for experts in life sciences.
    • Many members have challenged the very constitutionality of the FRA, making a travesty of the idea of “objectivity” in the process.

    (3) Criteria judging the damages

    • The criteria being used by the committees to determine the threat of “irreversible damage” to wildlife are quite extreme and are not supported by any consensus even among ecologists.
    • There are no objective criteria decided yet by these committees.

    Conclusion

    • The FRA begins by recognising that forest dwellers “are integral to the very survival and sustainability of the forest ecosystem”.
    • In that context, the CWH provision should not be seen as simply a tool for evicting forest-dwellers to create so-called “inviolate” spaces.
    • It is an opportunity to rigorously and participatorily explore all avenues of co-existence.
    • Such co-existence is indeed possible. In general, forest-dwellers harbour both the knowledge and the attitudes needed for conservation.
    • Co-managing PAs is, therefore, the most effective and socially just long-term solution, and relocation should be seen as the absolute last resort.

  • Species in news: Great Indian Hornbill

    A study based on satellite data has flagged a high rate of deforestation in a major hornbill habitat in Arunachal Pradesh.

    Try this PYQ:

    Q. In which of the following regions of India are you most likely to come across the ‘Great Indian Hornbill’ in its natural habitat? (CSP 2016)

    (a) Sand deserts of northwest India

    (b) Higher Himalayas of Jammu and Kashmir

    (c) Salt marshes of western Gujarat

    (d) Western Ghats

    About Great Indian Hornbill

    IUCN status: Vulnerable (uplisted from Near Threatened in 2018), CITES: Appendix I

    • The great hornbill (Buceros bicornis) also known as the great Indian hornbill or great pied hornbill, is one of the larger members of the hornbill family.
    • The great hornbill is long-lived, living for nearly 50 years in captivity.
    • It is predominantly fruit-eating, but is an opportunist and preys on small mammals, reptiles and birds.
    • Its impressive size and colour have made it important in many tribal cultures and rituals.
    • A large majority of their population is found in India with a significant proportion in the Western Ghats and the Nilgiris.
    • The nesting grounds of the birds in the Nilgiris North Eastern Range are also believed to support some of their highest densities.

    Their ecological significance

    • Referred to as ‘forest engineers’ or ‘farmers of the forest’ for playing a key role in dispersing seeds of tropical trees, hornbills indicate the prosperity and balance of the forest they build nests in.

    Threats

    • Hornbills used to be hunted for their casques — upper beak — and feathers for adorning headgear despite being cultural symbols of some ethnic communities in the northeast, specifically the Nyishi of Arunachal Pradesh.
    • Illegal logging has led to fewer tall trees where the bird’s nest.

    Back2Basics: Hornbill Festival

    • The Hornbill Festival is a celebration held every year from 1 – 10 December, in Kohima, Nagaland.
    • The festival was first held in the year 2000.
    • It is named after the Indian hornbill, the large and colourful forest bird which is displayed in the folklore of most of the state’s tribes.
    • Festival highlights include the traditional Naga Morungs exhibition and the sale of arts and crafts, food stalls, herbal medicine stalls, flower shows and sales, cultural medley – songs and dances, fashion shows etc.

  • Twin issues: Shrinking water bodies and floods in urban landscapes

    This newscard is an excerpt from the original article published in the D2E.

    Try this question for mains:

    Q.Shrinking water bodies and floods in urban landscapes are mutually induced by each other. Analyse.

    Water in urban landscapes

    • Lakes and wetlands are an important part of the urban ecosystem.
    • They perform significant environmental, social and economic functions — from being a source of drinking water and recharging groundwater to supporting biodiversity and providing livelihoods.
    • Their role becomes even more critical in the present context when cities are facing the challenge of rapid unplanned urbanisation.
    • Their numbers are declining rapidly. For example, Bangalore had 262 lakes in the 1960s; now only 10 of them hold water.

    Issues with urban water bodies

    • Natural streams and watercourses, formed over thousands of years due to the forces of flowing water in the respective watersheds, have been altered because of urbanisation.
    • As a result, the flow of water has increased in proportion to the urbanisation of watersheds.
    • Ideally, natural drains should have been widened to accommodate the higher flows of stormwater.
    • But, on the contrary, they have been a victim of various unlawful activities:

    (1) Pollution

    • There has been an explosive increase in the urban population without a corresponding expansion of civic facilities such as infrastructure for the disposal of waste.
    • As more people are migrating to cities, urban civic services are becoming less adequate.
    • As a result, most urban water bodies in India are suffering because of pollution. The water bodies have been turned into landfills in several cases.
    • Guwahati’s Deepor Beel, for example, is used by the municipal corporation to dump solid waste since 2006. Even the Pallikarni marshland in Chennai is used for solid waste dumping.

    (2) Encroachment

    • This is another major threat to urban water bodies. As more people have been migrating to cities, the availability of land has been getting scarce.
    • Today, even a small piece of land in urban areas has a high economic value.
    • These urban water bodies are not only acknowledged for their ecosystem services but for their real estate value as well.
    • Charkop Lake in Maharashtra, Ousteri Lake in Puducherry, Deepor beel in Guwahati are well-known examples of water bodies that were encroached.

    (3) Illegal mining activities

    • Illegal mining for building material such as sand and quartzite on the catchment and bed of the lake have an extremely damaging impact on the water body.
    • For example, the Jaisamand Lake in Jodhpur, once the only source of drinking water for the city, has been suffering from illegal mining in the catchment area.
    • Unmindful sand mining from the catchment of Vembanad Lake on the outskirts of Kochi has decreased the water level in the lake.

    (4) Unplanned tourism activities

    • Using water bodies to attract tourists has become a threat to several urban lakes in India.
    • Tso Morari and Pongsho lakes in Ladakh have become polluted because of unplanned and unregulated tourism.
    • Another example is that of Ashtamudi Lake in Kerala’s Kollam city, which has become polluted due to spillage of oil from motorboats.

    (5) Absence of administrative framework

    • The biggest challenge is the government apathy towards water bodies.
    • This can be understood from the fact that it does not even have any data on the total number of urban water bodies in the country.
    • Further, CPCB had not identified major aquatic species, birds, plants and animals that faced threat due to pollution of rivers and lakes.
