potato, brinjal, turmeric, ginger, cucurbitaceous crops, cole crops, legumi-
nous and leafy vegetables, tuber and rhizomatous crops and lesser-known
vegetables like tree bean, tree tomato, drumstick, chow-chow, kartoli,
Flemingia vestita
, etc. One of the areas in which there is tremendous po-
tential for investment and development is food processing. There is ample
scope for setting up a small and medium scale fruit processing units in
North East India.
5.3 PROJECTED CLIMATE CHANGE AND ITS IMPACT ON
HORTICULTURAL CROPS IN 2030S, NEH REGION (INCCA-2010)
5.3.1 CHANGES IN TEMPERATURE
The surface air temperature in this region is projected to rise by 25.8°C
to 26.8°C in the 2030s, with a standard deviation ranging from 0.8°C to
0.9°C. The rise in temperature with respect to the 1970s ranges from 1.8°C
to 2.1°C. Minimum temperatures are likely to rise from 1°C to 2.5°C and
maximum temperatures may rise by 1°C to 3.5°C. The Himalayan region
is likely to remain unaffected but changes in thermal stress are expected
in most parts of North-East region. In this region, the THI is likely to in-
crease between April-October months with THI > 80.
5.3.2 CHANGES IN PRECIPITATION
The mean annual rainfall is projected to vary from a minimum of 940±149
mm to a maximum of 1330±174.5 mm. The increase in the 2030s, with
respect to the 1970s, is of the order of 0.3% to 3%. In the North-Eastern
region, the number of rainy days is likely to decrease by 1-10 days. The
intensity of rainfall in the region is likely to increase by 1-6 mm/day.
The trend in precipitation in the North-Eastern region exhibits consider-
able spatial variability in water yield in the 2030s but is in line with the
projected patterns of precipitation and evapotranspiration. As compared
to the 1970s, in the 2030s the northern parts of the region show a reduc-
tion in precipitation that varies from 3% in the north-western part of the
North-East to about 12% in the north-eastern part. The central portion of
the North-East shows an increase in precipitation varying from 0% to as
