Water Hyacinth Livelihood Initiative in Assam

Syllabus: GS3/ Environment

Context

A livelihood initiative supported by the International Rhino Foundation has enabled women living near the Laokhowa-Burhachapori Wildlife Sanctuary in Assam to convert invasive water hyacinth into marketable household products.

Water Hyacinth (Eichhornia crassipes or Pontederia crassipes)

It is a free-floating, perennial aquatic plant native to tropical and subtropical South America.
It is widely recognized as one of the world’s most aggressive Invasive Alien Species (IAS).
It is famously referred to as the “Terror of Bengal” in India due to its devastating ecological and economic footprint.

Laokhowa-Burhachapori Wildlife Sanctuary (LBWLS)

Location – Situated on the southern bank of the Brahmaputra River in Assam
Ecological Connectivity: Strategically nestled between Kaziranga National Park to the east and Orang National Park to the west.
Vegetation – A mosaic of wet alluvial grasslands, riparian forests, moist deciduous woods, and significant wetland systems (like the Rowmari-Donduwa wetland complex).
Keystone Species: Great Indian one-horned rhinoceros, Royal Bengal Tiger, Asian elephant, and Asiatic water buffalo.

Syllabus: GS2/ International Relations

Context

Prime Minister Narendra Modi was conferred the prestigious Agricola Medal by the Food and Agriculture Organization (FAO) at its headquarters in Rome, Italy.
The medal was presented by FAO Director-General Qu Dongyu.

About Agricola Medal

The Agricola Medal is the highest honour conferred by the Director-General of the FAO.
The medal is named after Georgius Agricola, a German scholar widely considered the “father of mineralogy” and a pioneer in agricultural and mining sciences.
It is awarded to distinguished world leaders and individuals for exceptional and long-term contributions to global food security, sustainable agriculture, poverty reduction and improved nutrition.

Food and Agriculture Organization (FAO)

FAO is a specialized agency of the United Nations that leads international efforts to defeat hunger and improve food security.
It was founded on 16 October 1945.
Members: The FAO comprises 195 members, including 194 countries and the European Union.

Syllabus: GS3/ Science and Technology

Context

A recent study published in Nature Communications has provided evidence of the Zwan-Wolf effect at Mars using data from NASA’s MAVEN spacecraft.

Zwan-Wolf Effect

The Zwan-Wolf effect is a space weather phenomenon where electrically charged particles (plasma) are compressed and squeezed along magnetic field lines when a planet’s magnetic boundary interacts with the solar wind.
First identified in 1976 by scientists B.J. Zwan and R.A. Wolf.

Significance of Discovery

Mars lacks a strong global magnetic field unlike the Earth.
The discovery shows that even relatively “unmagnetised” planets can experience complex magnetic interactions.

MAVEN Mission

MAVEN stands for Mars Atmosphere and Volatile Evolution Mission.
It is a NASA mission launched in 2013 to study the Martian atmosphere and its interaction with the solar wind.
The mission investigates how Mars lost much of its atmosphere and water over time.

Connect with the basics – Mars

It is the fourth planet from the Sun
It is the second-smallest planet in the Solar System.
Mars is about half the size of Earth.
Rotation period – Its rotation period is 6 hours, which is very similar to that of Earth (23.9 hours).
Red Planet – The reason Mars looks reddish is due to oxidation or rusting of iron in the rocks, and dust of Mars. Hence it is also called the Red Planet.
Moon of Mars – Phobos and Deimos

Mars Orbiter Mission (MOM) or Mangalyaan

Launched from – Satish Dhawan Space Centre in Andhra Pradesh
Launched by – It was launched by Indian Space Research Organisation in November 2013.
Rocket used – PSLV C-25 rocket
Objective – To study Martian surface and mineral composition as well as scan its atmosphere for methane (an indicator of life on Mars).
