What we see happening is production being negatively affected by climate change as Times of India reports:
Across India — from east to west, south to north — the effects of climate change are seen to be slowly becoming apparent. Karnataka coffee, Assamese tea and Himachal apples are just three on a lengthening list of crops that are affected by changing climate patterns. Maharashtra's grapes, Goa's mangoes and cashew nuts, Kerala's paddy crops and Haryana's wheat — are seen to be affected too.
It's part of a change that is sweeping the globe, which the United Nations ' Food and Agricultural Organization took note of in September. At the time, the agency's assistant director general, Hafez Ghanem, predicted a turbulent long-term outlook for food prices across the world because of more frequent extreme weather due to climate change.

Down south, the Coffee Board of India has begun a special insurance scheme to help farmers cope but it admits it might find it hard to cushion them against the impact of sharply falling exports. Karnataka coffee is sent to Italy, Russia, France, Germany and the UK and Jayarama, the Coffee Board's director of research , says these markets may be put off by the declining quality of the coffee.
This, because coffee is acutely sensitive to rainfall and badly needs the blossom shower in the flowering season — mid-March — and the backing shower — roughly three weeks after that. This is crucial to bean development. Jayarama says the problem is the additional showers in January and February, which cause "the coffee crop to fruit twice or maybe three times." The beans that come later, he adds, are inferior.
