table 1.4 (continued) Climate change impacts on indian crop production

Crop Region Temperature CO 2 level Production impact Reference

Wheat, rice,
maize,
groundnut

Punjab 1°C, 2°C and

3°C increase

Increased Yield reduction in all the crops. Increased CO 2

increases crop production

Hundal and Kaur
(1996)

Wheat, winter
maize

Bihar Increased Increased Yield increase in winter maize but decrease in

wheat

Abdul Haris et al.
(2013)

Wheat India 1°C increase — Yield reduction Saini and Nanda

(1986)

Northern India 0-2°C rise 425 ppm At 1°C yield increased but reduced at 2°C with

reduced evapotranspiration

Aggarwal and
Sinha (1993)

India Increased — Yield decreased Gangadhar Rao and

Sinha (1994)

North, Central India
at high and lower
latitude; tropical
and sub-tropical

0-2°C rise 425 ppm At 1°C yield increased but reduced at 2°C

temperature. Sub-tropical reduction by 1.5-5.8
% but in tropical decrease was 17-18 %.
Slightly increased at high latitudes but
signiicant decrease at lower latitude. 10-15 %
yield reduction in Central India but non-
signiicant in north

Aggarwal and
Kalra (1994)

Sorghum Hyderabad, Akola

and Sholapur

Three
scenarios of
climate
change

Increased Yield reduction at Hyderabad and Akola but at

Sholapur marginally increased

Gangadhar Rao
et al. (1995)

India 1-2°C rise 50-700 ppm 7-12% reduction in yield. 50 ppm CO 2

increase, yield increased by 0.5% but was
nulliied with a rise of 0.08°C and 700 ppm by
a rise of 0.9°C
