Why in the News
On 18 May 2026, a Cluster-based Coffee Value Chain Development Mission was launched for Nagaland at an event linked to the Ministry of Development of North Eastern Region. Per PIB, the outlay of the "Coffees of Nagaland" mission is ₹175 crore. It proposes linking planting with post-harvest processing, quality, identity, marketing and market access.
Two pilot clusters are especially worth remembering: arabica at Tuophema in Kohima district and robusta at Ghotovi in Niuland district. These are the places chosen in the mission; they should not be understood as the only places growing these varieties in the whole state.
Identifying Arabica and Robusta:
Arabica's scientific name is Coffea arabica. Robusta coffee is associated with Coffea canephora. Both are related to the Rubiaceae family and the genus Coffea. Treating arabica and robusta as two local names of one species would not be correct.
Per the Coffee Board, some high and relatively cool regions of India are suitable for arabica, while warm and humid conditions suit robusta. The Board's general comparative table gives 15-25°C for arabica and 20-30°C for robusta. The given ranges of the two share some portion. So do not make a complete division like "arabica grows only in the cold and robusta only in the heat".
For both, deep, fertile, organic-matter-rich and well-drained soil is said to be useful. High rainfall alone does not ensure good cultivation; good drainage is also needed. Variety, elevation, slope, the timing of rainfall and local management should be seen together.
India's Coffee Regions:
Karnataka, Kerala and Tamil Nadu are India's traditional coffee regions. Andhra Pradesh and Odisha areas of the Eastern Ghats count among the non-traditional coffee regions. Coffee cultivation has also developed in the Northeast. So calling India's coffee limited to the Western Ghats would be wrong.
Karnataka's Bababudangiri is linked to the history of Indian coffee. But do not take this historic identity as the current percentage of production or the latest state-wise rank. Such figures change with the year and the estimate. This article makes no claim of production share without stating a year.
Why Does Shade-Grown Cultivation Matter?
One identity of India's coffee cultivation is growing with shade-giving trees. The Coffee Board describes a two-tier mixed shade canopy. Shade trees help reduce sharp temperature swings, save soil on slopes and return organic matter through fallen leaves.
Crops such as black pepper, cardamom, banana and orange are also grown with coffee. This is a multi-crop system. It does not mean every plantation holds all these crops.
Shade is useful, yet "the more shade, the more production" is not a correct rule. The Coffee Board advises proper management of shade. A commercial plantation with shade trees cannot, without examination, be taken as a full substitute for natural forest or an automatically biodiversity-safe area in every situation.
The Blossom Shower and the Later Rain:
In its discussion of cultivation, the Coffee Board states the difference between blossom showers and backing showers. The first rain matters in the stage linked to flowering. The supporting rain after it also matters for the process of the crop setting. In preparation, give weight not just to total annual rainfall but also to its timing and distribution.
The Board's general Indian table states blossom showers in March-April for arabica and February-March for robusta. These are pointers for understanding regional planning, not an unchangeable calendar for every place. The actual sequence of weather can differ.
The Difference Between Mission and Certification:
The Nagaland mission emphasises quality, branding, digital traceability, tourism and market access. Traceability means connecting a record of a product's origin and the stages of its supply chain. With it one can find where a product came from and through which steps it passed.
The PIB description also speaks of connecting organic certification and GI tagging. This should not be read as "the moment the mission began, every coffee got a GI" or "the state's entire coffee is certified organic". A programme's aim and a product's obtained certification are separate facts.
What Is the Coffee Board Linked To?
The Coffee Board is a statutory body created under the Coffee Act, 1942 and under the administrative control of the Ministry of Commerce and Industry. Its work includes research, extension, quality improvement and tasks linked to the development of coffee. Do not take it as a body created by Nagaland's new mission.
The Direction of Preparation from Past Questions:
Following the direction of formats like correct pairs and how-many-statements in the official General Studies Paper-I of UPSC Prelims 2023, prepare the matching of crop-region, species-condition and institution-ministry. All the questions below are original practice; they have not been called actual PYQs.
Prelims Style: Practice Questions
Question 1. Consider the following statements:
Statement 1: Both arabica and robusta are associated with the genus Coffea.
Statement 2: In the Coffee Board's general table, the suitable temperature ranges of the two share some portion.
Statement 3: In India, coffee is grown only in Karnataka, Kerala and Tamil Nadu.
How many of the above statements are correct?
(a) Only one
(b) Only two
(c) All three
(d) None
Answer and reason
Answer: (b) Only two. The first two are correct. The third is wrong: these are the traditional regions, but coffee is grown in the Eastern Ghats and the Northeast too.
Question 2. With reference to the Nagaland mission:
Consider the following pairs:
Pair 1: Tuophema, Kohima - arabica
Pair 2: Ghotovi, Niuland - robusta
Pair 3: the mission's launch - automatic GI registration for every coffee of the state
Which pairs are correct?
(a) Only 1 and 2
(b) Only 2 and 3
(c) Only 1 and 3
(d) 1, 2 and 3
Answer and reason
Answer: (a). The first two are the pilot clusters stated by PIB. The third is wrong: a scheme having GI tagging as an aim is not proof of every product getting automatic registration.
Question 3. Which statement is correct?
(a) The Coffee Board was created only for Nagaland's 2026 mission
(b) Other crops simply cannot be grown in shade-grown coffee cultivation
(c) The Coffee Board is a statutory body created under the Coffee Act, 1942
(d) Continuously increasing the amount of shade increases production in every condition
Answer and reason
Answer: (c). The Board is a statutory body linked to the Ministry of Commerce and Industry. Multi-crop cultivation is possible in a shade system, but proper management of shade is necessary; maximum shade cannot be taken as the rule for maximum production.
