  • This Ranger’s Mission is Save Himalaya

    This Ranger’s Mission is Save Himalaya

    According to Chaudhary, the other threats to the park include agriculture, traditional grazing and hydropower development…reports VISHAL GULATI

    Like other park rangers, Roshan Chaudhary normally leaves for patrolling in the morning and returns at sunset. And when there is a tip-off on the movement of poachers for several nights at a stretch he has to camp for the conservation of Western Himalayan biodiversity.

    His job as a Deputy Ranger was to protect the highly endangered species, ranging from the elusive endangered pheasant western tragopan to the musk deer and the Himalayan tahr in the Great Himalayan National Park, a Unesco World Heritage site in the north-west Himalayas, besides a host of native avifauna and mammals species and a large number of medicinal plants.

    Park authorities fear for their vulnerability from poaching from localised settlements in the buffer zone known as an eco-zone.

    This national park in the northern state of Himachal Pradesh, ranked as the best-managed protected area in the country by the Ministry of Environment, Forest and Climate Change in 2021, is characterized by high alpine peaks, alpine meadows and riverine forests with minimal tourism impact.

    The 90,540 ha property includes the upper mountain glacial and snow meltwater sources of several rivers, and the catchments of water supplies that are vital to millions of downstream users.

    “Human settlements pose the greatest threat to park fauna and flora species, besides illicit felling,” Chaudhary, the longest-serving official who retired on December 31 after serving the park in various capacities for 33 years, told.

    According to Chaudhary, the other threats to the park include agriculture, traditional grazing and hydropower development.

    He said most of the trekking routes are closely regulated by camera trapping devices.

    Locals often venture into forests in groups to collect the expensive herbs. They stay for weeks to collect them.

    “They are posing a serious challenge as they are familiar with the local typography and even sturdy compared to outside poachers,” Chaudhary, who trekked the rugged and inaccessibility park known for its significant size of 1,171 sq km on several occasions and separated from home and family for weeks or even months, told IANS in an interview on Monday.

    The park’s eco-zone has some 160 villages and hamlets, while the boundaries are connected to the Pin Valley National Park, the Rupi-Bhawa Wildlife Sanctuary and the Kanawar Wildlife Sanctuary.

    Park authorities normally involve locals in conservation of biodiversity at the park. Besides protecting it from the poachers, they are playing an important role for managing sustainable eco-sensitive or nature-based eco-tourism.

    The effective conservation management of habitat and endangered species is really a challenge for park authorities.

    “After a daylong strenuous trek over scree, boulders, and very narrow paths into high alpine meadows, the park offers fantastic places for stargazing — allowing you to gaze the night sky like never before,” he said, adding “That is the most relaxing moment in one’s life.”

    Regarding his favourite and the most challenging trek in the park, Chaudhary, who joined the park as a forest guard, said it is Shupakuni Pass between two wildlife ranges — Tirthan and Sainj. Normally it takes six-seven days to cover the trek.

    Starting at an altitude of 1,700 metres, the highest peak within the Himalayan park approaches 5,800 metres.

    The park, which is totally untouched by a road network, has four valleys — Tirthan, Sainj, Jiwa Nal and Parvati.

    According to Chaudhary, the Himalayan park holds religious significance as it is home several high-altitude Jognis, meaning prayer sites. During summer, the local deity and villagers visit these places.

    The Great Himalayan National Park, notified in 1999, is home to 209 bird species, including the western tragopan, the Himalayan monal, the koklas, the white-crested kalij and the cheer, all pheasant species.

    One of the richest biodiversity sites in the western Himalayas, the park supports the snow leopard, the Tibetan wolf, the Himalayan brown and black bear, the Himalayan blue sheep, the Asiatic ibex, the red fox, the weasel and the yellow-throated marten.

    The small mammals include the grey shrew, a small mouse-like mammal with a long snout, royal mountain vole, Indian pika, giant Indian flying squirrel, porcupine and the Himalayan palm civet, besides nine amphibians and 125 insects.

    Talking about the man-animal conflict, Chaudhary, who is wild at heart, told that animals in the wild mostly avoid any encounters with the humans — and when they do attack people, it is usually in self-defence.

    He said the snow leopard also needs protection from pastoral communities in alpine pastures.

    “The park supports a good population of the snow leopard with a sizable population of its prey species like the Asiatic ibex and the Himalayan blue sheep,” said Chaudhary, who had face-to-face encounters with the common leopard and the brown bear several times.

    “The wild animals rarely attack humans. They attack only when the people disturb them. I have spent nights in their habitat with just a rucksack carrying a raincoat, cap, sleeping bag and an LED torch and they just passed my rucksack without bothering me.”

    “Man-animal conflicts are more a social issue. For the conservation of the wildlife, you need cooperation of the local communities,” he added.

    Chaudhary advocated the need to link eco-tourism with the local communities. “If we fail to create awareness on wildlife, we will fail to preserve them for the future generations,” he added.

  • Shrinking forests, habitats leading to rising man-elephant conflict

    Shrinking forests, habitats leading to rising man-elephant conflict

    Herds of wild tuskers damaged huge quantities of crops, homesteads, residential homes and destroyed various other properties besides eating food stored in the homes of the villagers…reports Sujit Chakraborty

    With the degradation of forests and shrinking of habitats, human-elephant conflicts are rising in the northeastern states, mainly in Assam and Tripura, with 971 people being killed by wild elephants and 926 tuskers dying from diverse causes since 2010 in Assam.

    According to the latest census, India is home to 27,312 elephants and of them, Assam is home to 5,719 Asian elephants, the second largest elephant population in India after Karnataka (6049), a large number of whom often come out of the forests in search of food.

    According to the officials of Assam’s Forest and Environment department 71 elephants including elephant calves were killed this year mainly due to being hit by speeding trains, poisoning, electrocution, ‘accidental’ deaths including falling into ponds and ditches, lightning strikes while 61 people including women died this year in attacks by the jumbos.

    In May, 18 jumbos were killed by a lightning strike in Nagaon district of central Assam.

    Herds of wild tuskers damaged huge quantities of crops, homesteads, residential homes and destroyed various other properties besides eating food stored in the homes of the villagers.

    After Assam, the depredations of the wild pachyderms also took place in parts of western and and southern Tripura with four people killed by the elephants during this year in Khowai district alone.

    Most of the animal experts and researchers felt that the increasing number of deaths of both humans and wild elephants is due to growing urbanisation, inadequate steps of the governments and destruction of forests and the environment.

    According to the ‘India State of Forest Report-2019′, Assam has only 36.11 per cent forest cover out of the state’s total geographical area of 78,438 sq.km. Out of the total of 28,327 sq.km forest area in Assam, only 2,795 sq.km is very dense forest and 10,279 sq.km areas are moderately dense forest.

    Bibhuti Prasad Lahkar, Programme Secretary and Head, Elephant Research and Conservation Division of Aaranyak, an NGO on conservation, said that degradation of the habitat, lack of quality habitat and gradual shrinking of existing habitats cause man-elephant deaths and frequent conflicts.

    “Insufficient forest personnel, non-involvement of civil administration and other stakeholders is leading to a situation of great concern. Involvement of the villagers and volunteers to deal with the situation is very crucial,” he said.

    Lahkar said that the wild elephants hugely destroy crops, property and food of the villagers but they do not get sufficient compensation from the government.

    “If the poor villagers do not get compensation for their damaged crops and properties they will not be involved in the protection of wild animals and the environment,” he pointed out.

    Lahkar said that besides quality habitat, elephants require a huge amount of fodder and water, both of which are drastically reduced in the degraded forest and mountainous areas.

    Assam’s Forest and Environment Minister Parimal Suklabaidya said that the government has decided to create nine elephant corridors in the eastern part of the state.

    He said that a committee had been constituted to make an on-the-spot verification of the areas for delineation of nine animal corridors in the UNESCO world heritage site — Kaziranga National Park and Tiger Reserve — and the committee had submitted its report to the government.

    “The state government would take all possible steps to ensure the protection of wild animals specially the elephants, tigers and rhinos. We are also constantly spreading awareness among the people about the protection of the wild animals and their habitats,” the minister said.

    The state government also took numerous steps to stop illegal activities killing the animals and destroying forests and the environment.

    “Poaching of rhinos and elephants for their horn and tusks respectively has been drastically reduced following the steps taken by the forest department,” the minister said.

    “Coordination committees were constituted with all stakeholders and forest officials to coordinate to prevent accidental deaths of elephants along the railway lines.

    “Railway tracks in several vulnerable areas prone to elephant accidents and deaths have been identified. Forest and railway staff and other concerned people are monitoring those accident-prone areas while signages are displayed at vulnerable locations alerting the train drivers,” Suklabaidya said.

    Other steps taken to check the deaths of elephants due to speeding trains include cleaning of vegetation along the railway tracks to increase visibility, deployment of anti-depredation squads to prevent elephant fatalities due to train hits, using trained elephants (‘kunkis’) to monitor the movement of wild elephants.

    The Central Empowered Committee (CEC), set up by the Supreme Court, has recently asked the Assam government to take immediate action to remove illegal constructions in nine identified wildlife corridors of Kaziranga National Park and Tiger Reserve, which extends across Assam’s Golaghat, Nagaon, Sonitpur, Biswanath and Karbi Anglong districts along the Arunachal Pradesh border.

    An Assam Forest Department official said that the CEC’s Member-Secretary Amarnatha Shetty, in a letter to Chief Secretary Jishnu Baruah, asked for an action taken report within four weeks.

    “It is requested that immediate action be taken to remove all constructions made in violation of the Supreme Court order of April 12, 2019 and not to permit any new constructions along the nine identified animal corridors,” the letter said.

    The CEC has also referred to the inspection report submitted on September 10 by the Union Environment, Forest and Climate Change Ministry’s Integrated Regional Office, Guwahati, head Hemen Hazarika, which also enclosed the report of the Deputy Inspector General of Forest (Central) Lactitia J. Syiemiong, on “Violation of the Supreme Court order of April 12, 2019”.

    Besides the study of Syiemiong, Assam-based green activist Rohit Choudhury lodged a complaint with the Union Ministry on May 10 pointing out the illegal new constructions in the animal corridors in contempt of the Supreme Court’s direction.

    The official said that the Supreme Court earlier barred new construction on private land that forms part of the nine identified animal corridors of Kaziranga, which is home to more than 2,400 one-horned Indian rhinos.

    2021: A year of climate breakdown

    Yet in addition to the financial cost, these extreme weather events have caused severe human suffering from food insecurity, drought and extreme weather events, causing mass displacements and loss of life…reports Asian Lite News.

    A new report by Christian Aid — Counting the cost 2021: A year of climate breakdown — on Monday identified 15 of the most destructive climate disasters of the year.

    They include some of the disasters hit rapidly, like Cyclone Yaas, which struck India and Bangladesh in May and caused losses valued at $3 billion in just a few days.

    Ten of those events cost $1.5 billion or more. Most of these estimates are based only on insured losses, meaning the true financial costs are likely to be even higher.

    Among them is Hurricane Ida, which struck the US in August, costing $65 billion and killing 95 people. July floods in Europe cost $43 billion and killed 240, while floods in China’s Henan province caused $17.5 billion of destruction, killed 320 and displaced over a million.

    While the report focuses on financial costs, which are usually higher in richer countries because they have higher property values and can afford insurance, some of the most devastating extreme weather events in 2021 hit poorer nations, which have contributed little to causing climate change.

    Yet in addition to the financial cost, these extreme weather events have caused severe human suffering from food insecurity, drought and extreme weather events, causing mass displacements and loss of life.

    South Sudan has experienced terrible floods which has seen more than 850,000 people forced to flee their homes, many of whom were already internally displaced, while the East Africa continues to be ravaged with drought, highlighting the injustice of the climate crisis.

    Other events took months to unfold, like the Parana river drought in Latin America, which has seen the river, a vital part of the region’s economy, at its lowest level in 77 years and impacted lives and livelihoods in Brazil, Argentina and Paraguay.

    Four of the 10 most costly events took place in Asia, with floods and typhoons costing a combined $24 billion. But the impact of extreme weather was felt all over the world.

    Australia suffered floods in March which displaced 18,000 people and saw damage worth $2.1 billion while floods in Canada’s British Colombia led to $7.5 billion in damage and 15,000 people having to flee their homes.

    Insurance and financial loss data on the recent tornadoes in the US is incomplete, so is not included in this report but may be included in next year’s study.

    Worryingly such climate devastation is set to continue without action to cut emissions. Insurer Aon warns that 2021 is expected to be the sixth time global natural catastrophes have crossed the $100 billion insured loss threshold. All six have happened since 2011 and 2021 will be the fourth in five years.

    The report also highlights slow-developing crises such as the drought in the Chad Basin that has seen Lake Chad shrink by 90 per cent since the 1970s and threatens the lives and livelihoods of millions of the world’s poorest who live in the region.

    These extreme events highlight the need for concrete climate action. The Paris Agreement, set the goal of keeping temperature rise to below 1.5 degrees Celsius compared to pre-industrial levels, yet the outcomes from COP26 in Glasgow do not currently leave the world on track to meet this goal which is why much more urgent action is required.

  • Indian scientists reveal new layer of monsoon circulation’s link to Antarctica

    Indian scientists reveal new layer of monsoon circulation’s link to Antarctica

    South-easterlies become southwest (summer) monsoon winds after crossing the equator, therefore, a strong correlation between them is expected…writes Nivedita Khandekar

    Identifying several occurrences of interchanging intense and weak monsoon circulation events during the 145 kyr period (roughly a millennia), Indian scientists have found that warm/cold conditions in Antarctica show a near one-to-one coupling with weak/strong monsoon phases, suggesting a strong mechanistic link between them during the period.

    Four scientists from National Centre for Polar and Ocean Research (NCPOR), Goa, under the Ministry of Earth Sciences, and the School of Earth, Ocean and Atmospheric Sciences, Goa University, reconstructed the dynamics of the summer monsoon circulation from an upstream region, which is ideally suited for exploring its link with the southern high-latitude climate. The available records of past summer monsoon variability are predominantly based on reconstruction of downstream hydrology, which is identifiable with the thermodynamics of the system.

    Antarctica

    “The influence of northern high latitude climate variability on the South Asian Summer Monsoon has been extensively studied using both instrumental and proxy based climate data. In comparison, only a few studies have attempted to explore the southern high latitude association of the South Asian Summer Monsoon,” the study said.

    South Asian summer monsoon transports large amount of heat and moisture across the equator. A low-pressure system develops over the northwest Indian subcontinent and the Tibetan plateau as a result of sensible heating due to the seasonal position of the Sun. South-easterlies become southwest (summer) monsoon winds after crossing the equator, therefore, a strong correlation between them is expected.

    These scientists Manish Tiwari, Sidhesh Nagoji and Rahul Mohan from NCPOR, Goa and Vikash Kumar from Goa University, compared the 145 kyr long record of summer monsoon variability inferred through south-easterlies strength with that of earlier published 2003-reconstruction from the western Arabian Sea reflecting the southwest monsoon wind strength.

    They presented 145 kyr long new data – oxygen and carbon isotopic abundance of two depth-stratified species of foraminifera viz. Globigerinoides ruber and Globorotalia menardii – from a sediment core on sub-millennial to millennial scale resolution from the southwestern tropical Indian Ocean, a region swept by the southeasterly wind during boreal summer, which transforms to the southwest monsoon wind after crossing the equator.

    The findings from the study – published as ‘a 145 kyr record of upstream changes in Indian monsoon circulation and its link to southern high-latitude climate’ in journal ‘Polar Science’ in October – said “are consistent with our results where warm (cold) Antarctic conditions appear to cause synchronous decline (increase) in monsoon circulation, most likely through an equatorial Indian Ocean bridge”.

    The tropical Indian Ocean, apart from being directly affected by the summer monsoon winds, is also ideally suited for exploring any high southern-latitude inter-hemispheric influence on the circulation. “Here, we report oxygen and carbon isotopic abundance of two depth-stratified foraminifera species from a sediment core from the southwestern tropical Indian Ocean covering significant parts of the last two glacial periods,” the study said, adding: “Past upwelling record constructed using the oxygen isotopic composition of depth-stratified species of foraminifera indicates periods of high and low summer monsoon activity from 187.5 kyr to 41.4 kyr BP”.

    Antarctica

    The carbon isotopic composition primarily records signatures of monsoon induced upwelling during this period. Spectral and wavelet analysis shows dominant power in the precession band throughout the 145 kyr period. “Our record of summer monsoon variability matches with a multi-proxy record of monsoon wind stress from the Western Arabian Sea, a region dominated by high seasonal south-westerly summer monsoon wind. Comparison of our record with the Antarctic climate record during the last two glacial periods suggests coherent changes in cross-equatorial summer monsoon flow and Antarctic temperatures where warm (cold) conditions in Antarctica were phase linked to weak (strong) monsoon circulation.”

    It appears that millennial scale variability in the southern high latitude region significantly modulates sub-orbital variance of cross-equatorial monsoon flow, most likely by influencing the sea surface temperatures (SST) in the tropical Indian Ocean, the scientists said.

  • Climate activist Aditya Dubey’s  journey to Diana Award

    Climate activist Aditya Dubey’s journey to Diana Award


    During the course of the award ceremony, we had a sponsored trip to London where we attended various workshops and met wonderful people. It was a wonderful experience altogether…reports Asian Lite News.

    Eighteen-year-old climate activist Aditya Dubey’s continuous effort to fight off Delhi’s air pollution problem as a citizen led to the promulgation of the Commission For Management Of Air Quality (CAQM) in the national capital and its adjoining areas besides making him eligible to win the prestigious Diana Award this year.


    Established in 1999, the Diana Award, named after Princess of Wales — Diana, honours young people who work to improve the lives of others.

    In an exclusive interview, Aditya — one of the 20 young changemakers to bag the honour, talked about his journey, the award, climate movement and how it could become more inclusive.

    Excerpts from the interview:

    Tell us about your journey to the Diana Awards and what has changed since then?


    It is a great honour that the judges found me worthy of carrying on her (Princess Diana’s) legacy of social service forward. Much grateful for that.

    During the course of the award ceremony, we had a sponsored trip to London where we attended various workshops and met wonderful people. It was a wonderful experience altogether.

    Now, my words will have more weightage. For example, earlier people used to listen to me as a teenager but now maybe they will, in the sense of the legacy award, take my word in more regard so that we can work even better on environmental issues.

    What led you to become a climate activist in the first place?


    So, it all started in 2016 because of the air pollution crisis in New Delhi and National Capital Region (NCR) because it has been very bad over the past few years and I saw people facing respiratory problems due to the same. I, too, am suffering from sinusitis and asthmatic cough. Then people started wearing masks. That’s when we started staging protests and insisted that the government does something about it. However, when I felt that no heed was being paid to our demands, I moved the Supreme Court with my fellow petitioner Aman Banka seeking a direction to the government to take measures to solve the air pollution crisis.

    Last year, it led to the promulgation of the CAQM. However, since the air quality level has been very horrible this year so the hearings are going on weekly due.

    You had also started some campaigns like ‘Plant a Million Trees’ and ‘No Car Sundays’. What is the present-day status of these initiatives?


    My first campaign was the ‘Plant a Million Trees’ initiative which had started with the aim of planting a thousand trees but then I became too arrogant and increased the target to a million trees. Now I have a goal to plant a million trees within the next year and till now we have planted 1,88,000 trees.

    Another campaign called ‘No Car Sundays’ works on ways to encourage people to use public transport instead of a car on Sundays. It has been going on for a few months now where we regularly hold events in which people can cycle together.

    As an 18-year-old climate activist, did you face any kind of challenges during your campaigns?


    Because of my age, I have not been taken seriously. Even the government did not listen to us or paid attention to our protests as environmental issues are not voting issues right now. That is why we had to approach the Supreme Court.

    Having said that, I will not blame any one government for the poor condition of air in Delhi. State governments of Haryana, Punjab, Uttar Pradesh and the central government are equally responsible for not coordinating to find a common solution to the problem of stubble burning. We cannot blame farmers for burning the crop residue in the absence of an alternative. This is where the government should step in and give incentives to the farmers, provide stubble burning machines to them etc.

    Have you been following the global climate strike? What differences have you noticed in the climate movement in India and those taking place in other parts of the world?

    I have worked Fridays for Future (FFF) and Extinction Rebellion. We regularly held protests on Fridays, but to our dismay governments are not doing anything to address this crisis. In our culture, the environment is held in high regard, however, it is not given the due respect or attention by the governments. If we look at the present-day situation then Covid-19 is just a warning as to which level of destruction can take place due to climate change in the future. Also, there is no economic benefit in not dealing with climate change either. Look at the amount governments have to spend in the relief and rehabilitation of those affected by floods, cyclones, storms etc. There is an economic advantage in solving the climate crisis and those steps need to be taken urgently.

    We are also in touch with a few Members of Parliament (MPs) and we are hoping to bring in a climate change law in the near future.

    As for the differences in climate movement, in the developed parts of the world, governments listen to the masses. Here, the same is not the case. For example, look at the crores of money spent on the installation of smog towers in Delhi which are very ineffective. I believe that if the problem of air pollution becomes a voting issue only then something can be done about it.

    As a climate activist, how inclusive do you think the climate movement in India is?

    The climate movement in India is mostly restricted to the cities that is why it is being led by the privileged section of society. The lack of awareness is among the topmost reasons, why it is not inclusive of all the classes and communities in India.

    ‘Watershed’: An effort to correct ‘imbalance’

    She also noted that “as the climate heats up, it is likely that swathes of land will be submerged, water-related extremes will re-shape industry and famine will revisit the country.” (The first signs of this, in fact, are already visible.)…writes Vishnu Makhijani.

    Mridula Ramesh, a leading clean-tech angel investor with a portfolio of over 15 startups and who is involved in multiple initiatives to build climate entrepreneurship, ran out of water at her Madurai home in 2013.

    In trying to find out why that happened and what could be done about it, her first book, “The Climate Solution” and entry into the world of climate happened — only to realise that people speaking about climate change speak almost exclusively of carbon, while the climate itself speaks in the language of water.

    “For India, arguably one of the most vulnerable countries to the changing climate, water needs its share of the conversation,” and her new book, “Watershed” (Hachette India), “is an effort to correct that imbalance” because “we have crossed certain climate thresholds, and need to address water to lessen the pain that Indians are feeling in this changed climate”, Mridula told.

    More worrisome, the changing climate and water cycle “is highlighting inequalities — such as those between rich and poor within a given city and between the developed and developing world. Storms, flooding and drought affect the poor more than the rich,” she added.

    Moreover, looking at this through a climate justice angle, “we find that adaptation (a large part of which is managing water) is getting a far less conversation-share and lower share of financing than mitigation, even though developing countries have contributed far less to the cumulative GHG emissions that have caused this global warming. This lower priority only serves to increase existing inequalities,” Mridula explained.

    She also noted that “as the climate heats up, it is likely that swathes of land will be submerged, water-related extremes will re-shape industry and famine will revisit the country.” (The first signs of this, in fact, are already visible.)

    “Sea-level rise and stronger storms and stronger storm surges will result in parts of the country being underwater for at least some time each year in the future. Many industries came up in the belief that water is endless and cheap — climate change is challenging both of those beliefs. For example, sectors like thermal power plants in dry regions may find the going far less profitable, and may need to relocate or shutdown.

    “On famine, we have gone from a nation of 220 million eating largely millets to a nation of 1.3 billion eating rice and wheat. The price for this transformation has been paid largely from the groundwater reserved of the dry northwest. In 2019, a state committee had opined that Punjab may run out of groundwater in 20-25 years. What will happen if an El Nino hits after that? That’s what the plausible fictional scenario in Chapter 24 tries to portray � what can happen if all these come to pass in the near future,” Mridula cautioned.

    To this end, the book provides a five-point checklist of action:

    Acknowledge water — don’t take it for granted and see how India’s water is special. Acknowledge that we are the best keepers of our water resilience. Act with data and act now — begin by preparing a water balance sheet — where is it coming from and where is it going. Version 1.0 of this may not be perfect, but try every day to go a little further. The same holds true for a person, a community, a factory, a city, a state or a country.

    Protect the forces that soothe India’s volatile and variable waters — this includes forests, tanks and sewage treatment. In doing so, keep in mind the importance of cash flow — something may be very valuable and provide a great water-smoothening service, but if it does not generate cash flow, it becomes vulnerable in our economic world.

    Customers should recognise that there is no such thing as a free lunch. Ask your favourite brands to be conscious of their carbon/waste/water footprint, and ensure their entire supply chain is fairly compensated for respecting the environment.

    Let us recognise the power of decentralised policy — water pricing at the level of a city, mandating distributed farmgate storage in a district or sensitising bulk generators of waste/sewage, tank tourism — can generate a wave of innovation that can bring the jobs India needs while building climate resilience.

    We really are close to the abyss, and yet, most of our voters appear not to vote on managing our shared resources. This needs to change if we want meaningful policy action.

    Considerable research has gone into the book, with the studies conducted by the Madurai-based Sundaram Climate Institute forming one of its core pillars.

    “We have spoken to over 2,000 households on their waste and water realities apart from studying the communities and impact of 100 tanks. Then there was the historical research — many of which involved interviews, site visits and perusal of primary sources such as letters or writings of colonial officials. Then there was the peer-reviewed literature from archaeologists, geologists, chemists, hydrologists, climatologists, medical doctors, and historians,” Mridula elaborated.

    There were extensive interviews and conversations with a varied spectrum of people, from India’s ‘Water Man’ Rajendra Singh, to the many startups trying to build water resilience, to scientists, business people, activists, bureaucrats and politicians. And finally the investment process in startups.

    How does India compare with the rest of the world � with the US, Africa, and Europe?

    “In terms of climate and water vulnerabilities, India ranks high — very high — because of its population, its relative financial position, the large share of rainfed farms in agriculture and its long coastline. Also important to note is that the Indian Ocean has warmed faster than the other oceans in the world, leading to more powerful storms,” Mridula said.

    Speaking about her experience with her net-zero-waste home and how this can be replicated at the micro and macro levels, she said: “Before we did anything we collected data, what we wasted, who, why, how. Over time, patterns emerged and we began seeing what the biggest areas of waste were — so we brought the amount of ‘generated waste’ down.”

    “Second, we began to see how much of the ‘waste’ we could reuse — that is re-imagination, how to see ‘waste’ as a ‘resource’ — that was the killer step. We make compost and biogas, which keeps the garden healthy and the costs down. We also bring in waste from outside — flower waste and cow dung — to help with the compost and biogas.

    “We have had our successes and failures, but what has kept us going is the focus on data, and emphasis on making any action as easy to follow as possible,” Mriduala concluded.

    The Australian state of New South Wales (NSW) has braced itself for its first summer-like weather of the season, as temperatures were forecast on Wednesday to soar into the 40s in some parts of the state.

    Due to a La Nina weather event, Australia’s east coast has thus far experienced an atypical summer with heavy rain, thunderstorms, and flooding throughout many inland areas, Xinhua news agency reported.

    The dryer, hotter weather combined with strong winds prompted the Bureau of Meteorology (BoM) to issue a fire warning for NSW on Wednesday.

    BoM forecaster David Wilkie said the temperature increase would likely continue before reaching a max over the weekend.

    “When this next front moves through on Saturday, it’s going to drag the heat across the entire state… There’s also the risk that we could see some elevated fire dangers,” Wilkie said on Wednesday.

    The BoM also issued a warning of severe thunderstorms before the weekend in the state’s southeast.

    On Saturday, parts of inland NSW are expected to reach up to 45 degrees Celsius, while Sydney and coastal areas are expected to see temperatures hovering in the low 30s.

    Key contributor to Antarctic ice cloud cover found

    They found that there was a sizable difference in ice cloud formation at the low- and mid-levels (6500-20,000 feet) between summertime and winter…reports Asian Lite News.

    A study by Japanese scientists has explained how marine aerosols contribute to ice cloud formation over the Southern Ocean at comparatively high temperature conditions – a finding, which, in turn, will help improve the accuracy of climate models.

    Aerosols, or tiny particles suspended in the air upon which water vapour condenses at high altitudes, are a crucial factor to cloud formation, and understanding the contributions would help improve the accuracy of climate models, or digital simulations of the Earth’s climate system, calculating the interactions of various drivers of climate, such as land, sea, atmosphere, and humidity among others and forecast the future climate of the world.

    Yet, simulating clouds, a key factor of the Earth’s climate system, has always been challenging. Their complex behaviour often leads climate modellers to misestimate cloud cover.

    However, the climate scientist duo from Japan – Assistant Professor Kazutoshi Sato from Kitami Institute of Technology and Associate Professor Jun Inoue from the National Institute of Polar Research – have answered a few critical questions on cloud formation over Antarctica and the Southern Ocean in their research published in the journal ‘Geophysical Research Letters’.

    “Ice clouds are normally formed under very cold conditions (under minus 38 degrees C), but we observed the formation of low-level (under 6,500 feet) ice-clouds at significantly higher temperatures,” said Dr Sato.

    Breaking waves and squally winds disperse aerosols from the sea into the atmosphere. These particles then become the starting particles for a type of cloud called “ice clouds” and are hence called “ice-nucleating particles”. As the ice cover on the polar sea surface changes with temperature, the concentration and activity of the particles changes too, thereby influencing cloud formation.

    There are large uncertainties in current numerical climate models because of overestimation in ice-cloud fractions, especially in atmospheric and oceanic circulation. Understanding the sources of INPs will go a long way towards mitigating this issue, Dr Sato said.

    The scientists used data captured by the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite and estimated the seasonal variation in the ice cloud fraction over Antarctica and the Southern Ocean. They also investigated the relationship between low-level ice clouds and sea surface conditions in summer and winter.

    As marine phytoplankton blooms are considered a source of bioaerosols, the scientists also used the satellite data to measure the concentration of chlorophyll on the sea surface to provide an indicator of phytoplankton abundance in the upper layers of the ocean. Finally, they re-analysed the existing data to understand precisely the extent of gas and particle exchange between the ocean and atmosphere, said a release from the Kitami Institute of Technology, Japan.

    They found that there was a sizable difference in ice cloud formation at the low- and mid-levels (6500-20,000 feet) between summertime and winter. High fractions of low-level ice clouds were observed at comparatively high temperatures (above 7.5 degrees Celsius) over coastal Antarctic Sea ice areas in the summer. This increased ice cloud cover coincided with the highest estimated populations of phytoplankton. In winter, low-level ice clouds were observed at temperatures above 17.5 degrees C, a time during which substantial heat exchange took place from the ocean to the air near coastal areas.

    Sato said: “Our findings suggest that marine aerosols emitted from the ocean contribute to low-level ice-cloud formation over the Southern Ocean even under higher temperatures.”

    As ongoing climate change is causing rapid environmental changes, which are being felt acutely in the polar regions, Dr Sato highlighted the importance of their findings,

    “Developing reliable global climate models are essential to improving our understanding and predictions of climate behaviour. By clarifying the relationship between ice clouds and marine aerosols, our study will help reduce the errors associated with cloud biases in a numerical climate model.”

    “Improving the accuracy of climate models is the defining challenge of our time, but with findings like this to help us on our way, we are sure to succeed,” he said.

  • Delhi homes record poor indoor air quality

    Delhi homes record poor indoor air quality

    “In Delhi, the bottom line is — whether someone is rich or poor, no one gets to breathe clean air,” says Kenneth Lee, the lead author of the study. ..reports Asian Lite News.

    Delhi’s citizens long for clean air but do they call for it? A new two-year research at the Energy Policy Institute at the University of Chicago (EPIC India) has indicated that demand for air pollution information and defensive technologies may be low among India’s national capital residents.

    Researchers observed that even when offered a free trial of indoor air quality monitor to track pollution levels inside their homes, the take-up rates were low.

    The study found indoor PM2.5 levels for low-income and high-income households in Delhi were very high during the wintertime, with mean concentrations of 23 and 29 times the WHO safe limit of 10 Ig/m, respectively.

    Findings suggested that high-income households were 13 times more likely to own air purifiers than low-income households. Still, the indoor air pollution levels in those homes were only 10 per cent lower than those living in disadvantaged settings.

    “In Delhi, the bottom line is — whether someone is rich or poor, no one gets to breathe clean air,” says Kenneth Lee, the lead author of the study.

    “It’s a complex vicious cycle. When you do not know about the pollution levels inside your homes, you do not worry about it, and hence you are less likely to take corrective actions. Only with increased awareness, demand for clean air may gain momentum.”

    The experiment found that in homes with access to real-time indoor air pollution data, about an 8.6 per cent decline in indoor PM2.5 concentrations was recorded, and modest changes in inexpensive defensive practices and ventilation behaviours were observed.

    The researchers point out that the study that surveyed thousands of Delhi households between 2018 and 2020 across varying socioeconomic strata, on average, found the indoor PM2.5 levels to be substantially higher than the corresponding value reported by the nearest government monitor.

    Also, the study noted that indoor PM2.5 levels tend to spike in the mornings and evenings when households were most likely to be cooking.

    Lee adds: “It’s critical to address the information gaps related to indoor air pollution urgently. High-frequency accurate PM2.5 information communicated through either government monitor or by indoor air quality monitors is the first step but only when it is complemented with an increase in literacy around health consequences of air pollution and the benefits of adopting various defensive actions — can we expect more favourable outcomes.”
