Mains level: Coffee production in India
India’s Arabica production has hit an all-time low this coffee-picking season.
Coffee Production in India
- Coffee is grown in three regions of India with Karnataka, Kerala and Tamil Nadu forming the traditional coffee growing region.
- It is followed by the new areas developed in the non-traditional areas of Andhra Pradesh and Orissa in the eastern coast of the country and with a third region comprising the NE states.
- Indian coffee, grown mostly in southern states under monsoon rainfall conditions, is also termed as “Indian monsooned coffee”.
- The two well known species of coffee grown are the Arabica and Robusta.
History of Coffee in India
- In the Indian context, coffee growing started with a saint, Baba Budan who, while returning from a pilgrimage to Mecca, smuggled seven coffee beans from Yemen to Mysore in India.

From UPSC perspective, the following things are important :
Prelims level: Millimeter Spectrum
Mains level: Rolling out of 5G services in India
The DoT plans to auction the 24.75 – 27.25 gigahertz (GHz) spectrum in the 5G band in March-April 2020.
Millimeter Spectrum
- The new spectrum under the 5G band called the ‘millimeter-wave bands’ is separate from the 8,300 megahertz (MHz).
- The millimeter-wave band or extremely high-frequency frequency spectrum is mainly designed for usage in airport security scanners, closed-circuit television, scientific research, machine-to-machine communication, and military fire control.
What’s so special with this MM spectrum?
- As the wavelength becomes smaller, the cell size becomes less, which is the footprint of the relay station. This will be used more by the industry.
- If we you already have fiber connection and want to reach houses, this will be through millimeter bands.

From UPSC perspective, the following things are important :
Prelims level: Senna spectabilis
Mains level: Impacts of the invasive alien species
The Kerala Forest Department is planning to adopt steps to arrest the rampant growth of invasive plants, especially Senna spectabilis, in the forest areas of the Nilgiri Biosphere Reserve (NBR).
Senna spectabilis
- The Senna spectabilis species was planted as avenue trees in Wayanad. The vayal ecosystem (marshy land) of the forest area now has this plant in large numbers.
- The spread is posing a major threat to the forest areas of the reserve, owing to its quick growth and coppicing character.
- The tree species was found in nearly 10 sq km area of the 344.44 sq km sanctuary around five years ago.
- The plant has started to invade the adjacent Bandipur and Nagarhole tiger reserves in Karnataka and the Mudumalai tiger reserve in Tamil Nadu.
- Now, it had invaded to more than 50 sq km of the sanctuary Wayanad WLS.
- A recent study of the Ferns Nature Conservation Society recorded the presence of the plant in 78.91 sq km area of the sanctuary.
Impact
- An adult tree grows up to 15 to 20 metres in a short period of time and every year distributes thousands of seeds after gregarious flowering.
- The thick foliage arrests the growth of other indigenous tree and grass species and causes food shortage for the wildlife population, especially herbivores.
- Moreover, wildlife will not feed on the leaf of the treeas it is not palatable for them.
- The allelochemicals produced by this plant adversely affect the germination and growth of the native species.
