Temperate Fruits and Its Mitigation Strategies
Presentation for National workshop on âClimate Change Impact, Mitigation,
and Adaptation for Sustainable Horticulture,

2. Climate change sends India's apple farmers up the
Himalayas
âą Apples in the Himalayan foothills are seeing the worst effects
of climate change.
âą Temp. rose 0.6oC (global), 1.5oC (Himalayas) & 3.4oC (winter temp.)
âą reduction in snowfall by 36% (1980-2012),
âą Apple cultivation in low altitudes reduced by 77 % (Solan) 1987-
2007.
âą Areas turning from sub-temperate to sub-tropical

3. Arunachal apples losing taste due to climate
change
âą Apple produced in Arunachal Pradesh are now
gradually losing their taste and even turning
sour as a result of climate change.
âą Due to very heavily and erratic rains which
dilutes the sugar content of the crop

4. Temperate fruit growing regions in India
â North Western Himalaya (J&K, H.P., U.K.)
â Parts of North Eastern Himalaya (Arunachal Pradesh, Sikkim,
Meghalaya, Darjeeling)
â Horticulture is a backbone of the states economy.
â 75% people & 70% of GDP depends on Hort/agriculture
Features of temperate climate
â Extreme cool winters and mild summers
â Growing period range from <90 -120 days
â Fragile ecosystem with harsh and difficult terrain
â Undulating sloppy terraced land, high soil erosion & low
soil depth
â Chilling requirement for temperate fruits-mandatory

9. ïŒ Although, in one hand there has been seen
marked growth in area and production of
these crops but in other hand productivity
has left far behind as compared to
advanced countries.
ïŒ The low productivity is mainly attributed by
several factors including environmental,
physiological and biological.
ïŒ Over the years, environmental changes
playing a significant role like occurrence of
erratic rain, snowfall and increase in
temperature

13. ï±Shift in apple cultivation
towards higher altitude
and cold arid areas
ï± Shift in ecological zones
ï± Majority of the apple
orchards in UK have
become unproductive
over the year â low
chilling (?)
ï± Incidence and
resurgence of insect and
diseases of horticultural
crops
Apple production in Ladakh
(Future potential area)
Unproductive orchards

U.K.
Fruit bearing
peach trees in

14. ï± Mechanical damage
during active growing
stage directly
responsible for canker &
gummosis
ï±Hail storms and low
temperature during
spring â common
phenomenon now.
ï±Crop failure in high
chill fruit crops under
low altitutes
ï± Dry spell during late
spring and early
summers
Early blooming of fruit blossoms and
flowers due to warmer temperatures
during February and March in Kashmir has
been damaging fruit produce as sudden
late snows in February and March
devastate blossoms
15. Effect on flowering
ï± Bud burst is advanced
and the onset of growth
occurs earlier as in apple
where most of the trees
sprout 2-3 weeks earlier
than normal sprouting
(mid April )
ï± Due to change in bud
opening in March, they
may become Susceptible
to frost damage
Occurrence of late snowfall- causes heavy
damage to almonds- coincided with full bloom
Apricot in bloom-coincided with late
winter snow fall
16. ï± Apples fails to attain their
characteristic deep red
color if night temperature
are high (11.5 & 21)
ï± High temperature and
moisture stress increases
sunburn & cracking in
apples, apricot, cherry,
pomegranate etc.
Effect on fruit quality
17. ï± Wetter, warmer winters favours incidence
of diseases like Phytophthora,
Fusarium etc.
ï± Drier, warmer summers favours diseases
such as Alternaria, powdery mildew,
sooty bark diseases (under moisture
stress)
ï± Warm and humid temperature favours
apple scab
ï± Very dry summers results in increase in
population of red spider mite and aphids
--- more problem of attacks on apple
(Orson, 1999)
Effect of climate change on diseases and insects
Powdery mildew of apple
at dry and warmer
summers
Apple scab in warm
and humid
temperature
Mite attack on apple
Apple aphid in dry summer
Flea beetle in warm and
humid climate
Woolly aphis
18. ïIntroduction of low chilling cultivars.
ïDiversification with other high value fruit crops (peach,
apricot, olive , kiwi fruit etc.)
ïDevelopment of new genotypes having resistance to high
temperature.

29. II. Agro- techniques
ïŒProper drought management, moisture conservation,
critical irrigation, water harvesting)
ïŒAnti-hail nets/guns- prevent damage to some extent.
ïŒFoggy and cloudy weather-leads to russetting and
flyspeck-early genotypes and early harvest prevent damage.
ïŒWeather forecasting- helps in taking advance measures in
a changing scenario for predicting crop growth, yield, and
insect pests resurgence
34. ï±Energy harvest through plant architectural engineering.
ï±Espalier resulted in highest yield as compare to the Single axis.
ï±Coe Red Fuji and Granny Smith recorded highest yield 58.31 and
48.07 t/ha and 24.47 and 17.12 t/ha.
ï±Spindle Bush, Head and Spread and Modified Leader, the cultivar
Golden Delicious, Mollies Delicious and Starkrimson resulted in
highest yield.
38. ï± Development of disease insect forecasting system and
efficient management methods.
ï± Preparation of data base for development of model for
disease insect forecasting.
ï± Strengthening surveillance of pest and diseases
ï± To study the pattern of increasing climatic variability and
change could lead to rapid build up of pathogens and
insect pests
III. Plant protection strategies
39. Conclusion
ï± Climate change impacts are to be looked not in isolation but in conjunction
with all the aspect of agriculture and allied sectors
ï± Effects of climate change on horticulture sector are still uncertain
ï± In the light of possible global warming, researchers should give more
emphasis on development of heat- and drought-resistance crops
ï± Research is needed to define the current limits to these resistances and the
feasibility of manipulation through modern genetic techniques
ï± Both crop architecture and physiology may be genetically altered to adopt to
warmer environmental conditions
ï± At the regional level, those charged with planning for resource allocation,
including land, water, and agriculture development should also take climate
change into account
ï± Continuation of current and new initiatives of research so as to minimize the
effects of climate change at farm, regional, national and international level.
It will help to provide a detailed picture of how world horticulture and
agriculture could change.
ï± Formulation and implementations of policies and other adaptations in
horticultural systems that would minimize the negative effects of climate
change and exploits the beneficial effects
