Around the world, civil society groups and UN teams are hosting webinars, forums, summits and other diverse celebrations. It’s a collective effort that’s drawing together different wings of the UN from Educational, Scientific and Cultural Organization (UNESCO) to UN Peacekeeping.
Worldwide events
On Tuesday, Qatar launched a national biodiversity database, concluding a three-year UNEP-led project.
Mexico launched its 2025–2030 National Beach and Coastal Clean-Up and Conservation Campaign in Puerto Progreso, Yucatán, with volunteer brigades and a formal ceremony.
In Geneva, UNEP and the Orchestre des Nations are presenting a one-hour concert, Our Home, blending music, images and spoken word to highlight ecological emergencies.
Brussels is screening the documentary Ocean with legendary environmental campaigner and broadcaster Sir David Attenborough, in honour of World Environment Day, World Oceans Day and the UN Ocean Conference.
In a statement released Thursday, UNESCO reported that over 80,000 schools across 87 countries are following the recommendations in the Green school quality standard released in May 2024.
The initiative promotes green learning environments through governance, facilities and operations, teaching, and community engagement. This includes setting up “green governance committees” and training teachers in sustainable management practices.
Peacekeeping and the environment
In a video released Wednesday, UN Under-Secretary-General for Operational Support Atul Khare and Environment Section Chief Joanna Harvey outlined how UN Peacekeeping is reducing its environmental footprint.
Efforts over the past decade include bringing renewable energy to missions, requiring newer, more efficient generators, supporting local energy providers, and investing in sustainable infrastructure.
“We want to leave behind a legacy… [of] projects that are created by us which are finally beneficial to the local communities,” said Mr. Khare.
Between 19 and 23 million tonnes of plastic waste leak into aquatic ecosystems annually, and without urgent action, this figure is expected to rise by 50 per cent by 2040.
Plastic pollution is contaminating every corner of the planet, threatening ecosystems, wildlife, and human health. Microplastics are found in food, water and air, with the average person estimated to ingest over 50,000 plastic particles each year, and far more when inhalation is included.
If the climate crisis goes unaddressed, with plastic pollution as a major driver, air pollution levels exceeding safe thresholds could rise by 50 per cent within a decade. Meanwhile, plastic pollution in marine and freshwater environments may triple by 2040.
Global action day
To rally momentum, the UN Environment Programme (UNEP) is leading the 52nd annual World Environment Day on 5 June, the world’s largest platform for environmental outreach.
This year’s commemoration is hosted by Jeju, Republic of Korea, under the theme #BeatPlasticPollution. Since launching in 2018, the UNEP-led campaign has advocated for a just and inclusive transition away from plastic dependency.
The day brings together governments, businesses, communities, and individuals in a shared mission to protect and restore the planet, while advancing progress towards the Sustainable Development Goals (SDGs), especially those linked to climate action and sustainable consumption.
Towards a treaty
A major focus of the day is the ongoing push for a global treaty to end plastic pollution. Countries are currently negotiating an international, legally binding agreement, with the next round of talks scheduled for August.
UN Secretary-General António Guterrescalled for an “ambitious, credible and just agreement” that addresses the full lifecycle of plastics, reflects community needs, aligns with the SDGs and is implemented quickly and fully.
UNEP Executive Director Inger Andersen echoed the call, urging nations to unite around innovative solutions and alternatives to plastic use.
World Environment Day serves as a catalyst for action, driving attention toward the UN Environment Assembly later this year – where hopes are high that nations will finalise concrete steps to curb plastic pollution and address the broader climate emergency.
In a monumental effort to preserve the sanctity of Mount Everest and its neighboring peaks, the Nepalese Army has successfully retrieved four bodies and a skeleton, alongside a staggering 11 tonnes of rubbish, during a recent cleaning operation.
Since April, Nepalese soldiers have been diligently combing through the iconic peaks of Mount Everest, Lhotse, and Nuptse, striving to rid these majestic landscapes of accumulated waste and human remains.
Standing tall at 8,849 meters, Mount Everest holds the esteemed title of the world’s highest mountain, yet sadly, it has also become infamous for bearing the burden of being the planet’s highest rubbish dump.
Among the debris littering the slopes are broken tents, discarded clothing, food packaging, cookers, empty water bottles, beer cans, and oxygen cylinders, remnants left behind by the countless adventurers who have dared to conquer its formidable heights.
Tragically, along with the discarded waste, lies the somber reminder of human mortality, with dozens of corpses scattered across the terrain, some serving as morbid trail markers for passing climbers.
Recovering these fallen climbers presents a formidable challenge. The harsh conditions and extreme altitude make retrieval efforts perilous and prohibitively expensive, with estimates ranging between $32,000 to $64,500 per mission, as revealed by US mountaineer and blogger Alan Arnette.
Typically, a specialized team comprising six to ten experienced Sherpas equipped with oxygen cylinders is mobilized for the arduous task. In some instances, helicopters are employed to airlift the bodies from the mountain, a costly endeavor that underscores the immense logistical and financial burden associated with such operations.
As the cleanup initiative continues, the Nepalese Army remains steadfast in its commitment to preserving the pristine beauty of Mount Everest while honoring the memories of those who have perished on its unforgiving slopes.
The cities of the ancient Maya in Mesoamerica never fail to impress. But beneath the soil surface, an unexpected danger lurks there: mercury pollution. In a review article in Frontiers in Environmental Science, researchers conclude that this pollution isn’t modern: it’s due to the frequent use of mercury and mercury-containing products by the Maya of the Classic Period, between 250 and 1100 CE. This pollution is in places so heavy that even today, it pose a potential health hazard for unwary archeologists.
Lead author Dr Duncan Cook, an associate professor of Geography at the Australian Catholic University, said: “Mercury pollution in the environment is usually found in contemporary urban areas and industrial landscapes. Discovering mercury buried deep in soils and sediments in ancient Maya cities is difficult to explain, until we begin to consider the archeology of the region which tells us that the Maya were using mercury for centuries.”
Ancient anthropogenic pollution
For the first time, Cook and colleagues here reviewed all data on mercury concentrations in soil and sediments at archeological sites across the ancient Maya world. They show that at sites from the Classical Period for which measurements are available – Chunchumil in today’s Mexico, Marco Gonzales, Chan b’i, and Actuncan in Belize, La Corona, Tikal, Petén Itzá, Piedras Negras, and Cancuén in Guatemala, Palmarejo in Honduras, and Cerén, a Mesoamerican ‘Pompeii’, in El Salvador –mercury pollution is detectable everywhere except at Chan b’i.
Concentrations range from 0.016 ppm at Actuncan to an extraordinary 17.16 ppm at Tikal. For comparison, the Toxic Effect Threshold (TET) for mercury in sediments is defined as 1 ppm.
Heavy users of mercury
What caused this prehistoric mercury pollution? The authors highlight that sealed vessels filled with ‘elemental’ (ie, liquid) mercury have been found at several Maya sites, for example Quiriqua in Guatemala, El Paraíso in Honduras, and the former multi-ethnic megacity Teotihucan in Central Mexico. Elsewhere in the Maya region, archeologists have found objects painted with mercury-containing paints, mainly made from the mineral cinnabar.
The authors conclude that the ancient Maya frequently used cinnabar and mercury-containing paints and powders for decoration. This mercury could then have leached from patios, floor areas, walls, and ceramics, and subsequently spread into the soil and water.
“For the Maya, objects could contain ch’ulel, or soul-force, which resided in blood. Hence, the brilliant red pigment of cinnabar was an invaluable and sacred substance, but unbeknownst to them it was also deadly and its legacy persists in soils and sediments around ancient Maya sites,” said co-author Dr Nicholas Dunning, a professor at the University of Cincinnati.
cinnabar/wikipedia
As mercury is rare in the limestone that underlies much of the Maya region, they speculate that elemental mercury and cinnabar found at Maya sites could have been originally mined from known deposits on the northern and southern confines of the ancient Maya world, and imported to the cities by traders.
Health hazards and the ‘Mayacene’
All this mercury would have posed a health hazard for the ancient Maya: for example, the effects of chronic mercury poisoning include damage to the central nervous system, kidneys, and liver, and cause tremors, impaired vision and hearing, paralysis, and mental health problems. It’s perhaps significant that one of the last Maya rulers of Tikal, Dark Sun, who ruled around 810 CE, is depicted in frescoes as pathologically obese. Obesity is a known effect of metabolic syndrome, which can be caused by chronic mercury poisoning.
More research is needed to determine whether mercury exposure played a role in larger sociocultural change and trends in the Maya world, such as those towards the end of the Classic Period.
Co-author Dr Tim Beach, a professor at the University of Texas at Austin, said: “We conclude that even the ancient Maya, who barely used metals, caused mercury concentrations to be greatly elevated in their environment. This result is yet more evidence that just like we live today in the ‘Anthropocene’, there also was a ‘Maya anthropocene’ or ‘Mayacene’. Metal contamination seems to have been effect of human activity through history.”
New UMBC-led research in Frontiers in Microbiology suggests that viruses are using information from their environment to “decide” when to sit tight inside their hosts and when to multiply and burst out, killing the host cell. The work has implications for antiviral drug development.
A virus’s ability to sense its environment, including elements produced by its host, adds “another layer of complexity to the viral-host interaction,” says Ivan Erill, professor of biological sciences and senior author on the new paper. Right now, viruses are exploiting that ability to their benefit. But in the future, he says, “we could exploit it to their detriment.”
Not a coincidence
The new study focused on bacteriophages—viruses that infect bacteria, often referred to simply as “phages.” The phages in the study can only infect their hosts when the bacterial cells have special appendages, called pili and flagella, that help the bacteria move and mate. The bacteria produce a protein called CtrA that controls when they generate these appendages. The new paper shows that many appendage-dependent phages have patterns in their DNA where the CtrA protein can attach, called binding sites. A phage having a binding site for a protein produced by its host is unusual, Erill says.
Even more surprising, Erill and the paper’s first author Elia Mascolo, a Ph.D. student in Erill’s lab, found through detailed genomic analysis that these binding sites were not unique to a single phage, or even a single group of phages. Many different types of phages had CtrA binding sites—but they all required their hosts to have pili and/or flagella to infect them. It couldn’t be a coincidence, they decided.
The ability to monitor CtrA levels “has been invented multiple times throughout evolution by different phages that infect different bacteria,” Erill says. When distantly related species demonstrate a similar trait, it’s called convergent evolution—and it indicates that the trait is definitely useful.
A delta bacteriophage, the first identified in a new study in Frontiers in Microbiology to have binding sites for CtrA, a protein produced by the bacteriophage’s host that regulates the production of pili and flagella. The presence of these binding sites only in phages that require their host cells to have pili/flagella in order to infect them suggests that the phage is monitoring the presence of this protein in order to “decide” whether to stay put or replicate and emerge from its host cell./CREDIT:Tagide deCarvalho/UMBC
Timing is everything
Another wrinkle in the story: The first phage in which the research team identified CtrA binding sites infects a particular group of bacteria called Caulobacterales. Caulobacterales are an especially well-studied group of bacteria, because they exist in two forms: a “swarmer” form that swims around freely, and a “stalked” form that attaches to a surface. The swarmers have pili/flagella, and the stalks do not. In these bacteria, CtrA also regulates the cell cycle, determining whether a cell will divide evenly into two more of the same cell type, or divide asymmetrically to produce one swarmer and one stalk cell.
Because the phages can only infect swarmer cells, it’s in their best interest only to burst out of their host when there are many swarmer cells available to infect. Generally, Caulobacterales live in nutrient-poor environments, and they are very spread out. “But when they find a good pocket of microhabitat, they become stalked cells and proliferate,” Erill says, eventually producing large quantities of swarmer cells.
So, “We hypothesize the phages are monitoring CtrA levels, which go up and down during the life cycle of the cells, to figure out when the swarmer cell is becoming a stalk cell and becoming a factory of swarmers,” Erill says, “and at that point, they burst the cell, because there are going to be many swarmers nearby to infect.”
Listening in
“Everything that we know about phages, every single evolutionary strategy they have developed, has been shown to translate to viruses that infect plants and animals,” he says. “It’s almost a given. So if phages are listening in on their hosts, the viruses that affect humans are bound to be doing the same.”
There are a few other documented examples of phages monitoring their environment in interesting ways, but none include so many different phages employing the same strategy against so many bacterial hosts.
This new research is the “first broad scope demonstration that phages are listening in on what’s going on in the cell, in this case, in terms of cell development,” Erill says. But more examples are on the way, he predicts. Already, members of his lab have started looking for receptors for other bacterial regulatory molecules in phages, he says—and they’re finding them.
New therapeutic avenues
The key takeaway from this research is that “the virus is using cellular intel to make decisions,” Erill says, “and if it’s happening in bacteria, it’s almost certainly happening in plants and animals, because if it’s an evolutionary strategy that makes sense, evolution will discover it and exploit it.”
For example, to optimize its strategy for survival and replication, an animal virus might want to know what kind of tissue it is in, or how robust the host’s immune response is to its infection. While it might be unsettling to think about all the information viruses could gather and possibly use to make us sicker, these discoveries also open up avenues for new therapies.
“If you are developing an antiviral drug, and you know the virus is listening in on a particular signal, then maybe you can fool the virus,” Erill says. That’s several steps away, however. For now, “We are just starting to realize how actively viruses have eyes on us—how they are monitoring what’s going on around them and making decisions based on that,” Erill says. “It’s fascinating.”
Emotional eating, or eating as a coping mechanism for negative, positive, or stress-driven emotions, is associated with unhealthy dietary patterns and weight gain. A research article featured in the Journal of Nutrition Education and Behavior, published by Elsevier, discusses adolescent vulnerability to emotional eating and how various feeding practices used by parents, such as restriction, food as reward, and child involvement, influence eating behavior.
“Emotional eating was previously found to be more learned than inherited. This study examined not only the interaction between parents when feeding their children, but also what children learned from watching their parents eat,” said lead author Joanna Klosowska, MSc, Department of Public Health and Primary Care, Ghent University, Ghent, Belgium.
Eating/Photo:en.wikipedia.org
Over the four years between 2013 −2017, covering the time from late childhood to middle adolescence, changes occurred in some parental practices. Parents reported higher monitoring and healthy modeling feeding practices, while the reported levels of food restriction and the healthy environment remained unchanged. During the same time period, adolescents reported a considerable increase in emotional eating from below the average in 2013 to above the average in 2017, according to the norms for the Dutch population. Additionally, the maladaptive way in which they regulated their emotions was also associated with emotional eating.

Food as a reward and monitoring food increased emotional eating especially in instances where the adolescent employed maladaptive strategies in regulating their emotions. Child involvement in meals had an opposite effect since it was associated with higher levels of emotion regulation and lower levels of emotional eating. Interestingly, a parent’s restrained eating behavior was linked to less emotional eating in adolescents.
“This study suggests that parents continue to play an important role in their child’s eating behavior into their teen years,” said Klosowska. “Additional research is needed to understand the impact restrained eating demonstrated by a parent impacts the emotional eating of a child.”
An international team led by researchers at the RIKEN Cluster for Pioneering Research (CPR) has engineered a system for creating remote controlled cyborg cockroaches, equipped with a tiny wireless control module that is powered by a rechargeable battery attached to a solar cell. Despite the mechanic devices, ultrathin electronics and flexible materials allow the insects to move freely. These achievements, reported in the scientific journal npj Flexible Electronics on September 5, will help make the use of cyborg insects a practical reality.
Researchers have been trying to design cyborg insects—part insect, part machine—to help inspect hazardous areas or monitor the environment. However, for the use of cyborg insects to be practical, handlers must be able to control them remotely for long periods of time. This requires wireless control of their leg segments, powered by a tiny rechargeable battery. Keeping the battery adequately charged is fundamental—nobody wants a suddenly out-of-control team of cyborg cockroaches roaming around. While it’s possible to build docking stations for recharging the battery, the need to return and recharge could disrupt time-sensitive missions. Therefore, the best solution is to include an on-board solar cell that can continuously ensure that the battery stays charged.
All of this is easier said than done. To successfully integrate these devices into a cockroach that has limited surface area required the research team to develop a special backpack, ultrathin organic solar cell modules, and an adhesion system that keeps the machinery attached for long periods of time while also allowing natural movements.
Researchers at RIKEN, Japan have created remote controlled cyborg cockroaches, equipped with a tiny wireless control module that is powered by a rechargeable battery attached to a solar cell/RIKEN
Led by Kenjiro Fukuda, RIKEN CPR, the team experimented with Madagascar cockroaches, which are approximately 6 cm long. They attached the wireless leg-control module and lithium polymer battery to the top of the insect on the thorax using a specially designed backpack, which was modeled after the body of a model cockroach. The backpack was 3D printed with an elastic polymer and conformed perfectly to the curved surface of the cockroach, allowing the rigid electronic device to be stably mounted on the thorax for more than a month.
The ultrathin 0.004 mm thick organic solar cell module was mounted on the dorsal side of the abdomen. “The body-mounted ultrathin organic solar cell module achieves a power output of 17.2 mW, which is more than 50 times larger than the power output of current state-of-the art energy harvesting devices on living insects,” according to Fukuda.

The ultrathin and flexible organic solar cell, and how it was attached to the insect, proved necessary to ensure freedom of movement. After carefully examining natural cockroach movements, the researchers realized that the abdomen changes shape and portions of the exoskeleton overlap. To accommodate this, they interleaved adhesive and non-adhesive sections onto the films, which allowed them to bend but also stay attached. When thicker solar cell films were tested, or when the films were uniformly attached, the cockroaches took twice as long to run the same distance, and had difficulty righting themselves when on their backs.
Once these components were integrated into the cockroaches, along with wires that stimulate the leg segments, the new cyborgs were tested. The battery was charged with pseudo-sunlight for 30 minutes, and animals were made to turn left and right using the wireless remote control.
“Considering the deformation of the thorax and abdomen during basic locomotion, a hybrid electronic system of rigid and flexible elements in the thorax and ultrasoft devices in the abdomen appears to be an effective design for cyborg cockroaches,” says Fukuda. “Moreover, since abdominal deformation is not unique to cockroaches, our strategy can be adapted to other insects like beetles, or perhaps even flying insects like cicadas in the future.”
Large pieces of plastic can break down into nanosized particles that often find their way into the soil and water. Perhaps less well known is that they can also float in the air. It’s unclear how nanoplastics impact human health, but animal studies suggest they’re potentially harmful. As a step toward better understanding the prevalence of airborne nanoplastics, researchers have developed a sensor that detects these particles and determines the types, amounts and sizes of the plastics using colorful carbon dot films.
The researchers will present their results today at the fall meeting of the American Chemical Society (ACS). ACS Fall 2022 is a hybrid meeting being held virtually and in-person Aug. 21–25, with on-demand access available Aug. 26–Sept. 9. The meeting features nearly 11,000 presentations on a wide range of science topics.
“Nanoplastics are a major concern if they’re in the air that you breathe, getting into your lungs and potentially causing health problems,” says Raz Jelinek, Ph.D., the project’s principal investigator. “A simple, inexpensive detector like ours could have huge implications, and someday alert people to the presence of nanoplastics in the air, allowing them to take action.”

Millions of tons of plastic are produced and thrown away each year. Some plastic materials slowly erode while they’re being used or after being disposed of, polluting the surrounding environment with micro- and nanosized particles. Nanoplastics are so small — generally less than 1-µm wide — and light that they can even float in the air, where people can then unknowingly breathe them in. Animal studies suggest that ingesting and inhaling these nanoparticles may have damaging effects. Therefore, it could be helpful to know the levels of airborne nanoplastic pollution in the environment.
Previously, Jelinek’s research team at Ben-Gurion University of the Negev developed an electronic nose or “e-nose” for monitoring the presence of bacteria by adsorbing and sensing the unique combination of gas vapor molecules that they release. The researchers wanted to see if this same carbon-dot-based technology could be adapted to create a sensitive nanoplastic sensor for continuous environmental monitoring.
Carbon dots are formed when a starting material that contains lots of carbon, such as sugar or other organic matter, is heated at a moderate temperature for several hours, says Jelinek. This process can even be done using a conventional microwave. During heating, the carbon-containing material develops into colorful, and often fluorescent, nanometer-size particles called “carbon dots.” And by changing the starting material, the carbon dots can have different surface properties that can attract various molecules.
To create the bacterial e-nose, the team spread thin layers of different carbon dots onto tiny electrodes, each the size of a fingernail. They used interdigitated electrodes, which have two sides with interspersed comb-like structures. Between the two sides, an electric field develops, and the stored charge is called capacitance. “When something happens to the carbon dots — either they adsorb gas molecules or nanoplastic pieces — then there is a change of capacitance, which we can easily measure,” says Jelinek.
Then the researchers tested a proof-of-concept sensor for nanoplastics in the air, choosing carbon dots that would adsorb common types of plastic — polystyrene, polypropylene and poly(methyl methacrylate). In experiments, nanoscale plastic particles were aerosolized, making them float in the air. And when electrodes coated with carbon-dot films were exposed to the airborne nanoplastics, the team observed signals that were different for each type of material, says Jelinek. Because the number of nanoplastics in the air affects the intensity of the signal generated, Jelinek adds that currently, the sensor can report the amount of particles from a certain plastic type either above or below a predetermined concentration threshold. Additionally, when polystyrene particles in three sizes — 100-nm wide, 200-nm wide and 300-nm wide — were aerosolized, the sensor’s signal intensity was directly related to the particles’ size.
The team’s next step is to see if their system can distinguish the types of plastic in mixtures of nanoparticles. Just as the combination of carbon dot films in the bacterial e-nose distinguished between gases with differing polarities, Jelinek says it’s likely that they could tweak the nanoplastic sensor to differentiate between additional types and sizes of nanoplastics. The capability to detect different plastics based on their surface properties would make nanoplastic sensors useful for tracking these particles in schools, office buildings, homes and outdoors, he says.
Rising temperatures are harmful to wheat yields. However, crop yields do not provide a holistic vision of food security. The impacts of climate change on wheat price, livelihood and agricultural market fundamentals are also important to food security but have been largely overlooked.
An international research team has now estimated the comprehensive impact of climate change and extreme climate events on global wheat supply and the demand chain in a 2 ℃ warmer world by using a novel climate-wheat-economic ensemble modelling approach.
The effect of CO2 fertilization could cancel out temperature stress on crops, with a slightly greater wheat yield under 2 ℃ warming as a result. However, increases in global yield do not necessarily result in lower consumer prices. Indeed, the modelling results suggest that global wheat price spikes would become higher and more frequent, thus placing additional economic pressure on daily livelihood.
The findings, by scientists from six countries, were published in One Earthon August 19.
“This counterintuitive result is initially driven by uneven impacts geographically. Wheat yields are projected to increase in high-latitude wheat exporting countries but show decreases in low-latitude wheat importing countries,” said lead author ZHANG Tianyi, an agrometeorologist at the Institute of Atmospheric Physics, Chinese Academy of Sciences.
Co-author Karin van der Wiel, a climate scientist at the Royal Netherlands Meteorological Institute, further explained: “This leads to higher demand for international trade and higher consumer prices in the importing countries, which would deepen the traditional trade patterns between wheat importing and exporting countries.”
Earlier researchers pointed out that trade liberalization would help mitigate climate stress via improving market mobility. The current research team revealed that such policies could indeed reduce consumers’ economic burden from wheat products. However, the impact on farmers’ income would be mixed. For example, trade liberalization policy under 2 ℃ warming could stabilize or even improve farmers’ income in wheat exporting countries but would reduce income for farmers in wheat importing countries.
“These results would potentially cause a larger income gap, creating a new economic inequality between wheat importing and exporting countries,” said WEI Taoyuan, co-author and an economic scientist at the CICERO Center for International Climate Research. ZHANG further explained more dependence on imports could lower the wheat self-sufficiency ratio, thus causing a “vicious negative cycle” for wheat importing and less-developed countries in the long term.
“This study highlights that effective measures in trade liberalization policies are necessary to protect grain food industries in importing countries, support resilience, and enhance global food security under climate change,” said Frank Selten, a researcher at the Royal Netherlands Meteorological Institute and co-author of the study.
India and Finland on Thursday, Nov 26, 2020 signed an MOU for developing cooperation between two countries in the field of Environment protection and biodiversity conservation.
The MoU is a platform to further advance Indian and Finnish partnership and support, exchange best practices in areas like prevention of Air and water pollution; Waste management; Promotion of circular economy, low-carbon solutions and sustainable management of natural resources including forests; Climate change; Conservation of Marine and Coastal Resources; etc.
The MoU was signed virtually by Prakash Javadekar, Minister of Environment, Forest and Climate Change from the Indian side and Krista Mikkonen, Minister of the Environment and Climate Change, Government of Finland from the Finnish side.
Speaking at the event Javadekar said that the MoU also provides the possibility to have joint projects in areas of mutual interest. “This MOU will definitely commits us to work together more closely towards on the fulfilment of commitments made under Paris Agreement.”, said the Environment Minister.
Javadekar also informed that India has achieved its voluntary target of reducing emissions intensity of its GDP by 21% over 2005 levels, by 2020 and is poised to achieve 35% reduction well before the target year of 2030.
As part of its Nationally Determined Contributions submitted under the Paris Agreement , India has taken three quantitative climate change goals viz. reduction in the emissions intensity of Gross Domestic Product by 33 to 35 percent by 2030 from 2005 level, achieving about 40 percent cumulative electric power installed capacity from non-fossil fuel based energy resources by 2030 and creating an additional carbon sink of 2.5 to 3 billion tonnes of carbon dioxide equivalent through additional forest and tree cover by 2030.
The MoU will strengthen technological, scientific and management capabilities and develop bilateral cooperation in the field of environmental protection and biodiversity conservation on the basis of equality, reciprocity and mutual benefit with due respect to promotion of sustainable development.
A strain of the disease responsible for killing off nearly two thirds of the UK’s greenfinches has been discovered in myna bird populations in Pakistan.
Mynas are native to the Indian subcontinent and are one of the world’s most invasive species. Although the disease is not generally fatal to them, experts from the University of East Anglia studying the birds say there is a risk they might pass it on to other species.
Avian trichomonosis, more commonly called canker or frounce, is carried by a parasite that primarily infects pigeons in the UK and the larger birds of prey which feed on them.
But in 2005 scientists found the disease had jumped into Britain’s garden songbird populations, predominantly affecting greenfinches and chaffinches.
Since then, the greenfinch population in the UK has fallen from around 4.3 million breeding pairs to fewer than 1.5 million in 2016.
In 2011, the disease was discovered to have reached European finch populations. Now researchers at the University of East Anglia (UEA) have found it in an entirely separate songbird species – the common myna.
Working in partnership with the University of Agriculture in Pakistan, researchers captured and screened 167 myna birds from eight different sites around the Faisalabad region of Pakistan. They discovered that around 20 per cent of the birds were infected with the disease and that there were infected birds at all of the sites surveyed.
The study, published in the journal Parasitology, also identified that the disease affecting the mynas was a different strain from the one found in the UK songbirds. Few of the infected birds had signs of poor health, suggesting that they can carry the disease without it being fatal.
Because myna birds are so invasive, however, there is a significant risk that they can spread the disease to other species that might not otherwise come into contact with it.
Dr Kevin Tyler, from UEA and a senior author of the study, said: “Mynas are able to roost almost anywhere in warm climates, which is one reason they are so successful, but it could also mean they are likely to spread the disease further.
“Mynas have already been implicated in the spread of bird flu through contact with poultry, so this could be of concern to poultry farmers. However, further research and testing is needed to see whether the disease has yet spread from mynas to other species.”
He added: “In the UK, pigeons carry this disease without serious symptoms and it looks like myna birds are able to do the same. This could be due to a natural resilience to the disease, or it could be that this is a less virulent strain – again, we need to carry out further research to investigate.”
Although mynas are thought to be native to the Indian subcontinent, populations of the birds have spread around the world, so the team is also keen to test for the disease in other countries.
The National Water Policy (2012) formulated by Ministry of Water Resources, RD & GR, inter-alia, advocates conservation, promotion and protection of water and highlights the need for augmenting the availability of water through rain water harvesting, direct use of rainfall and other management measures. The National Water Policy (2012) has been forwarded to all State/UTs and concerned Central Government Ministries/ Departments for adoption.
Further, Government of India has circulated a Model Bill to all the States/UTs to enable them to enact suitable ground water legislation for its regulation and development, which includes provision of rain water harvesting. So far, 15 States/UTs have adopted and implemented the ground water legislation on the lines of Model bill. Also, Central Ground Water Authority (CGWA) has been constituted under “The Environment (Protection) Act, 1986” for the purpose of regulation and control of ground water development and management in the Country. CGWA has so far notified 162 areas in the Country for the purpose of regulation of ground water. CGWA has also issued advisories to States and UTs to take measures to promote/adopt artificial recharge to ground water / rain water harvesting. So far, 30 States/UTs have made rain water harvesting mandatory by enacting laws or by formulating rules & regulations or by including provisions in their building bye-laws or through suitable Government Orders.
Other steps taken by the Central Government to control depletion of ground water resources are available at the following URL http://mowr.gov.in/writereaddata/GW_Depletion.pdf.
As per CGWA guidelines, any user withdrawing groundwater for industrial/ infrastructure / mining project has to obtain ‘No Objection Certificate (NOC)’. Any withdrawal of ground water without valid NOC from CGWA is liable to have penal action under Section 15 of ‘The Environment (Protection) Act, 1986’, under which imprisonment for a term which may extend upto five years or with fine which may extend to one lakh rupees, or with both with provisions for additional fine of Rs.5,000/- per day for continued failure or contravention.
Central Ground Water Board conducts and facilitates research in ground water domain by taking up research projects at its Training and Research Institute.
Central Government is also encouraging R&D studies to ensure safe ground water. CGWB under Indian National Committee on Ground Water (INCGW) R&D programme is sponsoring Research Project for groundwater. Under the R&D scheme of MoWR, RD&GR, budget is allocated for sponsoring research in water resource sector that includes groundwater component and funds are allocated through INCGW.

China and India together contributed for more than half of the total global deaths due to air pollution in 2015, said a study by the U.S.-based Health Effects Institute (HEI).
The report showed that air pollution caused more than 4.2 million deaths in 2015, making it the fifth highest cause of death. But just two countries – India and China alone reported 2.2 million deaths, or half of the global deaths.
The institute on its website – www.stateofglobalair.org – said 92% of the world’s population lives in areas which are filled with polluted or unhealthy air. In turn, air pollution causes cancer, stroke and heart disease, as well as chronic respiratory problems such as asthma.
However, China is trying to bring down the deaths but India has a long time to go, it said. In January, a ministry spokesman told domestic media, “It is currently too early to draw conclusions about the extent of the impact of smog on health, especially its long-term impact on the body.”
The report said most of the world’s population lives in areas where air quality is unhealthy and an estimated 92% of people live in areas where fine particulate matter concentrations (small dust or soot in the air) exceed the World Health Organization’s Air Quality Guideline of 10 µg/m3.
Air pollution is a complex mixture of particles and gases and the composition varies from place to place, depending on what sources are present, including power plants, heavy industry, traffic, weather conditions, and how they mix in the atmosphere, said the organisation in it study.

Union Minister for State for Power, Coal, New & Renewable Energy and Mines Piyush Goyal in a written reply in Lok Sabha on Thursday said that a comprehensive scheme including Intra-State and Inter-State transmission system has been identified as a part of ‘Green Energy Corridors’.
The German air agency KfW Germany is providing soft loan to be funded as 20% equity of the State government, 40% grant from National Clean Energy Fund (NCEF) and 40% soft loan, whereas, the inter State transmission schemes are to be funded as 30% equity by PGCIL and 70% as soft loan, he said.
For Inter-state transmission projects pertaining to Part A, B and C of Green Energy Corridor, loan agreement for financial assistance of Euro 500 million from KfW, Germany has been signed by PGCIL and the projects are likely to be completed by 2018. Further, for implementation of transmission schemes under Green Energy Corridor-Part D, PGCIL has taken loan from ADB.
For Intra-state transmission projects under Green Energy Corridor; the States of Tamil Nadu, Rajasthan, Himachal Pradesh, Andhra Pradesh, Gujarat and Madhya Pradesh have signed the loan agreements from KfW, Germany for financial assistance of Euro 76 million, Euro 49 million, Euro 57 million, Euro 68 million, Euro 114 million and Euro 124 Million respectively.
Further, Goyal added that in order to integrate solar parks with the grid, Ministry of Power assigned PGCIL to implement Inter-State transmission scheme for evacuation from 8 solar parks (7200 MW). Transmission scheme for 6 solar parks (5750 MW) is already under implementation [Ananthapuram (1500 MW), Pavagada (2000 MW), Rewa (750 MW), Bhadla-III (500 MW), Bhadla-IV (250 MW), Essel Saurya (750 MW)]. Tender issued for Banaskantha Solar Park (700 MW), whereas Long Term Access (LTA) application for other MP solar park from the developer is awaited.
To evacuate power from the renewable capacity addition in renewable rich States (Andhra Pradesh, Gujarat, Himachal Pradesh, Karnataka, Maharashtra, Rajasthan, Madhya Pradesh and Tamil Nadu), transmission system strengthening, both Intra State and Inter State, along with setting up of Renewable Energy Management Centre (REMC) and the control infrastructure is being implemented under GECs.
