Prelims level: Miyawaki Forests
Mains level: Urban forestry
Central Idea: Prime Minister during his latest ‘Mann ki baat’ episode spoke about Miyawaki plantation, the Japanese method of creating dense urban forests in a small area.
Try this question:
Q.The Miyawaki Forests technique has to potential to revolutionize the concept of urban afforestation in India. Discuss.
Miyawaki Method
Miyawaki method is a method of urban afforestation by turning backyards into mini-forests.
It includes planting trees as close as possible in the same area which not only saves space, but the planted saplings also support each other in growth and block sunlight from reaching the ground, thereby preventing the growth of weed.
Thus the saplings become maintenance-free (self-sustainable) after the first three years.
It helps to create a forest in just 20 to 30 years while through conventional methods it takes anywhere between 200 to 300 years.
The technique
The native trees of the region are identified and divided into four layers — shrub, sub-tree, tree, and canopy.
The quality of soil is analysed and biomass which would help enhance the perforation capacity, water retention capacity, and nutrients in it, is mixed with it.
A mound is built with the soil and the seeds are planted at a very high density — three to five sapling per square meter.
The ground is covered with a thick layer of mulch.

Prelims level: Chromosomes
Mains level: Not Much
Central Idea
The Y chromosome, often known as the “master of maleness,” has fascinated scientists and historians for its role in determining sex and its unique genetic characteristics.
This article explores the intriguing journey of the Y chromosome, its significance, and recent discoveries that challenge previous assumptions.
What are Chromosomes?
Chromosomes are fundamental components of cells that play a vital role in storing and transmitting genetic information.
These structures contain genes, which carry instructions for the development, functioning, and inheritance of traits.
Chromosomes consist of tightly coiled DNA molecules wrapped around proteins called histones, forming chromatin.
Before cell division, chromosomes replicate into identical sister chromatids held together at the centromere.
Types of Chromosomes:
Autosomes: Non-sex chromosomes (22 pairs in humans) determine most traits.
Sex Chromosomes: Determine biological sex (XX for females, XY for males).
Functions of Chromosomes
Genetic Information Storage: Genes on chromosomes encode instructions for protein production and cellular processes.
Inheritance: Chromosomes transmit genetic information during sexual reproduction through meiosis, ensuring genetic diversity in offspring.
Gene Expression Regulation: Chromosomes control gene activation or silencing, crucial for development and cell functioning.
Significance of Chromosomes
Understanding Genetic Disorders: Abnormalities in chromosomes cause conditions like Down syndrome, aiding diagnosis and comprehension.
Evolutionary Insights: Comparative analysis of chromosomes reveals evolutionary relationships and genetic material changes over time.
Advancements in Genetic Research: Chromosomes are crucial for genome sequencing, mapping, and studying gene expression, leading to improved understanding of human health, diseases, and targeted therapies.
Our focus: Y Chromosome
Genetic Origins: The Y chromosome is believed to have emerged approximately 200-300 million years ago in a common ancestor of mammals. Its genetic sequence, published in 2003, revealed that it accounts for only 2% of the genetic material inside a cell, encoding around 55 genes.
Quirks and Challenges: Referred to as the “juvenile delinquent” among chromosomes, the Y chromosome has repetitive sequences, a limited number of genes, and a reluctance to recombine with other chromosomes. These characteristics have led to debates about its functional utility and evolutionary trajectory.
Significance of the Y Chromosome
Historical Insights: Researchers have extensively studied the Y chromosome to understand human migration and evolution. It has provided valuable insights into paternity, genetic diversity, and our shared past.
Beyond Sex Determination: Contrary to earlier assumptions, recent studies have revealed that the Y chromosome plays a role in biological functions beyond sex determination. It contains genes associated with aging, lifespan regulation, and other vital processes.
Influence of the Y chromosome on Health
Sex Differences in Lifespan: In the animal kingdom, including mammals, females tend to live longer than males. The absence of a second Y chromosome in males exposes detrimental mutations in the X chromosome, potentially contributing to shorter lifespans.
Age-Related Loss of the Y Chromosome: Studies have shown that men experience a loss of the Y chromosome (LoY) with age, which has been associated with a higher risk of diseases such as cancer and Alzheimer’s. Research on mice models supports these findings, indicating a correlation between LoY and shorter lifespans and memory deficiencies.
Phenotypic Sex and Longevity: Recent research on fruit flies challenges the notion that the presence of a Y chromosome directly influences longevity. Instead, the phenotypic sex of an individual, determined by external genitalia, may play a more significant role.
Future of the Y Chromosome
Species-Specific Evolution: Some species, like rodents, have naturally lost their Y chromosome, offering insights into sex-chromosome turnover. These species serve as models for understanding the process and the potential repurposing of other chromosomes as sex chromosomes.
Signs of Replacement: Genomic analysis of Neanderthal DNA indicates that the Y chromosome has undergone replacement in the lineage leading to modern humans. This suggests that the Y chromosome’s role as the “master of maleness” may eventually be overtaken by another chromosome in the future.

Central Idea
Delay in Monsoon: Any discussion on Indian monsoon delay these days invariably has references to the El Nino phenomenon.
Sudden rise of El Nino: This year’s monsoon is also progressing under the cloud of an El Nino in the Pacific Ocean.
Understanding El Nino and La Nina
El Nino and La Nina are two opposite phases of the El Nino-Southern Oscillation (ENSO) cycle.
ENSO is a naturally occurring phenomenon that involves the interaction between the ocean and atmosphere in the equatorial Pacific.
Here is a detailed comparison of El Nino and La Nina

Sea surface temperature in the equatorial Pacific Ocean rises above normal levels
Sea surface temperature in the equatorial Pacific Ocean drops below normal levels
Changes in the atmospheric circulation patterns
Changes in the atmospheric circulation patterns
Shift in the location of the jet stream, affecting the strength and direction of the monsoon winds
Increase in the strength of the monsoon winds, bringing more moisture and rainfall to India
Results in reduced rainfall, dry spells, and heatwaves, leading to crop failures and water scarcity
Excessive rainfall can also lead to floods and landslides, causing damage to crops and infrastructure
El Nino and Indian Monsoon
El Nino and its impact on Indian monsoon: El Nino refers to abnormal warming of surface waters in the equatorial Pacific Ocean, which tends to suppress monsoon rainfall in India.
Phases of El Nino Southern Oscillation (ENSO): ENSO consists of three phases in the Pacific Ocean: El Nino, La Nina (abnormal cooling), and a neutral phase with sea surface temperatures close to long-term averages.
Ocean and atmospheric conditions: ENSO involves not only temperature abnormalities of sea surface waters but also atmospheric conditions, including differences in sea-level air pressure and wind strength and direction.
Southern oscillation and the role of winds: Southern Oscillation Index measures the difference in sea-level air pressure over the western and eastern sides of the Pacific Ocean, while wind patterns play a crucial role in ENSO.
Factors triggering El Nino
Weakening trade winds: When the trade winds in the tropical Pacific weaken, it contributes to the occurrence of El Nino by reducing the movement of warm surface waters.
Changes in ocean currents: Alterations in the normal patterns of ocean currents can trigger El Nino events as they affect the distribution and accumulation of warm water in the central and eastern Pacific.
Variations in atmospheric pressure: Fluctuations in atmospheric pressure patterns disrupt the typical circulation associated with trade winds, which can initiate the onset of El Nino conditions.
Influence of oceanic Kelvin waves: The presence and behavior of oceanic Kelvin waves, large-scale waves that transport warm water eastward, play a role in the development and intensification of El Nino events.
Interactions with other climate modes: El Nino can be influenced by the interactions and connections with other climate phenomena such as the Indian Ocean Dipole and the Madden-Julian Oscillation, which can impact the oceanic and atmospheric conditions in the Pacific region.
Measuring the Cycle
(1) Oceanic Nino Index (ONI)
Measures the oceanic component of El Nino Southern Oscillation (ENSO).
Tracks the departure from average sea surface temperatures in the tropical Pacific Ocean.
Helps quantify the intensity and duration of El Nino or La Nina events.
Typically based on a rolling three-month average of sea surface temperature anomalies in specific regions.
(2) Southern Oscillation Index (SOI)
Measures the atmospheric component of ENSO.
Quantifies the difference in air pressure between two locations: Tahiti and Darwin.
Positive SOI values indicate higher pressure in the eastern Pacific and lower pressure in the western Pacific.
Negative SOI values indicate lower pressure in the eastern Pacific and higher pressure in the western Pacific.
Reflects the strength and changes in the atmospheric circulation patterns associated with ENSO.
Used to assess the phase and strength of ENSO and its impact on global weather and climate patterns.
Economic impact of El Nino on Indian Agriculture
Drought and reduced rainfall: El Nino events often lead to below-average monsoon rainfall in India, resulting in drought conditions in various regions.

Prelims level: Green Hydrogen
Mains level: Read the attached story
Central Idea
Researchers from IIT-Madras have developed components for a cost-effective method of electrolyzing seawater to produce green hydrogen.
The current alkaline water electrolyzer technology is energy-intensive, requires an expensive oxide-polymer separator, and uses fresh water.
Generating Green Hydrogen
Instead of using fresh water, the researchers developed an electrolyzer that utilizes alkaline seawater.
Carbon-based support material was used for the electrodes to minimize corrosion.
Transition metal-based catalysts were designed to catalyze both oxygen and hydrogen evolution reactions, improving the production of hydrogen and oxygen.
A cellulose-based separator was developed to allow hydroxide ions to pass through while preventing crossover of oxygen and hydrogen.
How does Electrolysis take place?
The alkaline water electrolyzer involves two half-reactions at the anode and cathode.
At the cathode, water dissociates into H+ and hydroxide ions, with H+ ions converting into hydrogen.
Hydroxide ions produced at the cathode pass through the separator, and oxygen is generated at the anode.
When seawater is used, hypochlorite formation occurs at the anode, causing corrosion and reducing oxygen production. Impurities also affect the hydrogen evolution reaction at the cathode.
How were the Catalyst and Electrode designed?
The carbon-based support material was used for both anode and cathode electrodes to prevent corrosion.
The catalyst coating on the support material enhances hydrogen production at the cathode and oxygen production at the anode.
Transition bimetals in the catalyst are selective toward oxygen evolution reaction, overcoming the challenge of hypochlorite formation.
Despite impurities adsorbed on the cathode, the catalyst promotes hydrogen evolution, increasing hydrogen production.
What made this device novel?
The team developed a cellulose-based separator to separate the anode and cathode.
The separator allows hydroxide ions to pass through but minimizes the crossover of hydrogen and oxygen.
The separator shows high resistance to degradation in seawater.
Experimental Results and Performance
The assembled electrolyzer achieved a seawater splitting voltage of 1.73 V at 10 mA/sq.cm and 26 degrees C.
The optimized parameters enable the electrolyzer to directly use photovoltaic-derived voltage for green hydrogen production.
Two prototypes of different dimensions were developed, producing hydrogen at rates of 250 ml/hour and 1 liter/hour.
A stack of three cells produced hydrogen at a rate of about 4 liters/hour.
