The Droughts are causing irreversible and reversible changes in the soil of wetlands globally. Pixabay

In a major study, researchers have shown how droughts are threatening the health of wetlands globally.

Published in the journal Earth-Science Reviews, the study highlights the many physical and chemical changes occurring during droughts that lead to severe, and sometimes irreversible, drying of wetland soils.


“Wetlands around the world are incredibly important for maintaining our planet’s biodiversity and they store vast amounts of carbon that can help fight climate change,” said study author Luke Mosley from the University of Adelaide in Australia.

According to the researchers, wetlands can suffer “water droughts” both from the effects of a drier climate, and also when excessive water is extracted or diverted that would normally flow into them.

The review paper describes how drought often leads to severe cracking and compaction, acidification, loss of organic matter, and enhanced greenhouse gas (for example methane) emissions.

In some cases, droughts can lead to very long-term (less than 10 years) and irreversible soil changes, with major impacts on water quality when soils are re-wet after the drought ends.

“We have seen many examples of how the drought in the Murray-Darling Basin in Australia has caused major issues including acidification of soil and water due to acid sulfate soils exposure in wetlands,” Mosley said.

“This review highlights substantial gaps in our global understanding of the effects of drought on wet soils and how they will respond to increasing drought,” Mosley added.

The researchers revealed that effects can be different in different soil types and different regions of the world.

The spatial distribution of drought studies shows there has been limited assessment in a large number of regions, including south and central America, Africa, the Middle East, Asia, and Oceania. Many of these regions are predicted to be vulnerable to drought impacts due to climate change.

“At a global level, wet soils are highly vulnerable to the effects of climate change and need to be protected given the very high environmental and socio-economic values they support,” the study authors wrote.

“It is our sincere hope that the information in this review contributes to protecting these valuable ecosystems,” they noted. (IANS)

Children playing ringa ringa roses in an open backyard in England

Great historic events that have shaped the world and changed the outlines of countries are often not recorded in memory, or so we think. Wars made sure to destroy evidence and heritage, and the ones who survived told the tale of what really happened. Folklore, albeit through oral tradition kept alive many such stories, hidden in verse, limericks, and rhymes.

Ringa-ringa-roses, a common playtime rhyme among children across the world, is an example of folklore that has survived for many centuries. It tells the story of the The Great Plague of London which ravaged the city between 1665-1666.

Certain tribes have remained matrilineal, where the decision-making power rests with the eldest female of the family.

In modern times, many social movements aim to bring reform to the society we live in, on the basis of certain existing patterns. Patriarchy is something that many aim to cleanse our cultures of, to usher in the era of social and gender equality. Despite all these so-called movements, in southern India, certain societies that patronise matriarchy have existed since before India's independence. The Nairs and Ezhavas of Kerala, and Bunts and Billavas of Karnataka are matrilineal societies that continue to thrive in a patriarchal country.

Kerala remains separate from the rest of India in many ways. Be it literacy policy, form of government, or cultural practices, this state does not always conform to the ideal that India is known for. Even so with their social structure. Certain tribes have remained matrilineal, where the decision-making power rests with the eldest female of the family.
