Wetlands are amongst the most productive ecosystems on the Earth and provide many important services to human society. They exhibit enormous diversity according to their genesis, geographical location, water regime and chemistry, dominant species, and soil and sediment characteristics. Globally, the areal extent of wetland ecosystems ranges from 917 million hectares (m ha) to more than 1275 m ha. One of the first widely used wetland classifications systems, devised by Cowardin et al., 1979, categorized wetlands into marine (coastal wetlands), estuarine (including deltas, tidal marshes, and mangrove swamps), lacustrine (lakes), riverine (along rivers and streams), and palustrine ( marshes, swamps and bogs) based on their hydrological, ecological and geological characteristics.

Ramsar Convention on Wetlands was an international treaty signed in 1971. Overall, 1052 sites in Europe; 289 sites in Asia; 359 sites in Africa; 175 sites in South America; 211 sites in North America; and 79 sites in Oceania region have been identified as Ramsar sites or wetlands of International importance.

As per the Ramsar Convention definition most of the natural water bodies (such as rivers, lakes, coastal lagoons, mangroves, peat land, coral reefs) and man- made wetlands (such as ponds, farm ponds, irrigated fields, sacred groves, salt pans, reservoirs, gravel pits, sewage farms and canals) in India constitute the wetland ecosystem distributed in different geographical regions ranging from Himalayas to Deccan plateau. As of February, 2022, India has 49 Ramsar sites covering an area of 10,93,636 hectares, the highest in South Asia. As per the estimates, India has about 757.06 thousand wetlands with a total wetland area of 15.3 m ha, accounting for nearly 4.7% of the total geographical area of the country . Out of this, areas under inland wetlands accounts for 69%, coastal wetlands 27%, and other wetlands (smaller than 2.25 ha) 4%.

Gujarat has the highest proportion (17.5%) and Mizoram has the lowest proportion (0.66%) of the area under wetlands. Among Union Territories, Lakshadweep has the highest proportion (around 96%) and Chandigarh has the least proportion (3%) of geographical area under wetlands.

Under which category of wetlands, are delta and mangrove swamps included?

Ram had never thought much about the origin of wealth or inequalities in life. It was his firm belief that if this world was not good, the next would be good, and this faith sustained him. He was not like some others whom he knew, who would sell their souls to the devil. He always thought of God before doing anything. He lived the life of an honest man. He had not married but did not desire another man’s wife. He believed that women weakened men as was described in the story of Samson and Delilah.

The effects of the worst economic downturn since the Great Depression are forcing changes on state governments and the U.S. economy that could linger for decades. By one Federal Reserve estimate, the country lost almost an entire year's worth of economic activity – nearly $14 trillion – during the recession from 2007 to 2009. The deep and persistent losses of the recession forced states to make broad cuts in spending and public workforces. For businesses, the recession led to changes in expansion plans and worker compensation. And for individual Americans, it has meant a future postponed, as fewer buy houses and start families. Five years after the financial crash, the country is still struggling to recover." In the aftermath of [previous] recessions there were strong recoveries. That is not true this time around," said Gary Burtless, a senior fellow at the Brookings Institution. "This is more like the pace getting out of the Great Depression." For years, housing served as the backbone of economic growth and as an investment opportunity that propelled generations of Americans into the middle class.

But the financial crisis burst the housing bubble and devastated the real estate market, leaving millions facing foreclosure, millions more underwater, and generally stripping Americans of years' worth of accumulated wealth. Anthony B. Sanders, a professor of real estate finance at George Mason University, said even the nascent housing recovery can't escape the effects of the recession. Home values may have rebounded, he said, but the factors driving that recovery are very different than those that drove the growth in the market in the 1990s and 2000s. Sanders said more than half of recent home purchases have been made in cash, which signals investors and hedge funds are taking advantage of cheap properties. That could freeze out average buyers and also mean little real economic growth underpins those sales. Those effects are clear in homeownership rates, which continue to decline. In the second quarter of this year, the U.S. homeownership rate was 65.1%, according to Census Bureau data, the lowest since 1995. In the mid-2000s, it topped 69%, capping a steady pace of growth that began after the early 1990s recession. Reversing that will be a challenge, in part because credit has tightened and lending rules have been toughened in an effort to avoid the mistakes that inflated the housing bubble in the first place.

"Credit expanded, and now contracted, and it's going to be tight like this as far as the eye can see," Sanders said. "We so destroyed so many households when the bubble burst, there's just not the groundswell to fill the demand again." Some are skeptical that the tight credit market and new efforts to regulate the financial markets, like the Dodd-Frank law, will prove lasting. Americans have often responded with calls for regulation after financial sector-driven crises and accusations of mismanagement, according to Brookings' Burtless. "But eventually, those fires cool down," he said. "It's not as though this memory of what can go wrong sticks with us very long." That can be seen in the intense efforts to water down Dodd-Frank's regulations, Burtless said. Federal regulators have already made moves to relax requirements for some potential homeowners who were victims of the recent housing crisis. Even those steps and an unlikely return to easy credit might not fuel a full housing recovery without economic growth to back it up. As Sanders, referring to the growth in low-wage and part-time employment, put it: "At those wages, it's tough to scramble together down payments and mortgages’’.

 "Turmoil in the housing market has already reshaped the makeup of households nationwide. Homeownership rates among people with children under 18 fell sharply during the recession, declining 15% between 2005 and 2011, according to Census Bureau data. In some states it was far worse. For Michigan, the decline in homeownership was 23%, and in Arizona and California it was 22%. Lackluster job growth has outlived the downturn. A study by the Economic Policy Institute showed wages for all workers, when adjusted for inflation, grew just 1.5% between 2000 and 2007. But the last five years wiped out even those modest gains—the study found wages declined for the bottom 70% of all workers since the recession began. However, some areas have seen manufacturing jobs climb back from recessionary lows, and the energy sector has been a boon for some Midwestern states. One hopeful sign for workers is the shift away from manufacturing growth in the typically low-wage South back toward the Rust Belt states, reversing a movement that was taking hold before the downturn. That trend is documented in a 2012 report from the Brookings Institution, "Locating American Manufacturing: Trends in the Geography of Production.’’

"From 2000 to 2010, both the Midwest and South lost manufacturing jobs at about the national rate of 34%. But the Midwest has seen nearly half of all manufacturing jobs gained since 2010, almost double the increase in the South. For Michigan, the growth was 19%; in Indiana, 12%. Even with that growth, there are caveats. Autoworker unions have ceded ground with companies on wages and benefits, for example, allowing new hires to work for lower pay and fewer benefits than those who've held their jobs longer. Unemployment remains stubbornly high in some states, and the jobs created have leaned heavily toward part-time and low-pay work. A study from the San Francisco Federal Reserve found the proportion of U.S. jobs that are part-time is high, as many of the jobs lost during the recession have not returned.

The most logical and intelligent people seem to go berserk when talking about snakes. Recently a reputed scientist said with a wise look in his eyes that sand boas have two heads. The other day someone walked into my office and stated that in his village at least cobras mate with rat snakes. About other places he was not sure, he added modestly, but that was how it was in his village.

These stories about snakes are myths. Sand boas have only one head; vine snakes do not peck your eyes out; no snake will drink milk. But it is interesting to try and trace the origin of these untruths. The one about the sand boas two heads obviously exists because the short, stumpy tail of this snake looks remarkably like the head, an effective device to fool predators. Or take the one about vine snakes pecking at eyes. It was ‘probably started by a vine snake that had a bad aim, as snakes, when provoked, will bite the most prominent projection of the offender, which is usually the nose.

But the most interesting one is about snakes coming to the scene of killing to take revenge. It so happens that when injured or under stress, a snake exudes, a large quantity of musk. Musk is a powerful sex attractant, the snakes’ equivalent of after-shave lotion. So after a snake is killed, the ground around still has this smell and naturally a snake of the same species passing by will lick its lips and come to investigate. The killer of the snake, who is probably worried if the pooja he performed was adequate to liquidate the killing of a snake, sees the second snake and is convinced that it was not.

The Irula tribals have a good answer to the query about whether cobras have jewels in their heads; “If they did, we wouldn’t be snake catchers, we would be rajas!”

The number of Indian students going abroad for higher studies has increased by 68.79 per cent in the past year, according to data provided by the Minister of State in the Ministry of Education, Subhas Sarkar. As per the data provided by him in the Lok Sabha, the number of Indians enrolled in foreign varsities increased from 4.44 lakh in 2021 to 7.5 lakh in 2022. He clarified that while the Bureau of Immigration and Ministry of Home Affairs maintain departure and arrival data of Indians, there is no index for capturing the category of Indians going abroad for higher education. “Purpose of Indians going abroad for higher education is captured manually based either ontheir verbal disclosure or the type of visa of the destination country produced by them at the time of immigration clearance,” Sarkar said. According to the data provided by the ministry, the number of Indian nationals increased from 4.54 lakh in 2017 to 5.17 lakh in 2018. There was a significant increase in 2019 as well, with 5.86 lakh students flying out of the country. However, during the Covid pandemic, the number of Indian nationals in foreign varsities saw a drastic dip as only 2.59 lakh students were registered. While the number continued to remain low, it saw a slight increase in 2021 with 4.44 lakh registrations. However, the number has significantly jumped to 7.5 lakh in 2022. The increase in the number of Indian nationals abroad corresponds with the latest immigration reports from some of the popular study-abroad destinations such as the US, UK, and Australia. For the UK, the Immigration Statistics Report states that 127,731 visas were granted to Indian students in September 2022, an increase of 93,470 (+273 per cent) against 34,261 in 2019. Similarly, in the US, the number of Indian students has more than doubled, and the Open Doors Report 2022 has predicted that the number of Indian students heading to America is likely to surpass those from China in 2022-23.

How do we know the number of students getting visas for studies in UK?

There is a general consensus that ‘International Understanding’ need to be taught as a separate subject at the school stage as that would add to the curricular load which is already too heavy. Instead it should be woven into the curriculum and the numerous opportunities that present themselves while teaching normal school subjects may be intelligently and imaginatively used by the teacher to promote International Understanding.

The school subjects which can be most profitably used for this purpose are History, Geography, Civics, Economics, Sociology, Political Science, Social Sciences, Languages as well as Physical and Life Sciences. However, at the higher education level, international education can be prescribed as a separate subject of study. In fact, the present situation in India broadly conforms to this consensus so far as the school stage is concerned.

At the under-graduate and the post-graduate levels, courses of study in subjects like History, Geography, Economics, Political Science, International Relations, International Law and International Organization have been prescribed by most of the universities and these contain content which has a direct or indirect bearing on promoting UNESCO ideals

Pick out the name of the subject which deals with the study of society.
