A considerable change in climate at a global level will impact the
vegetable cultivation and agriculture as a whole; subsequently
affecting the world's food supply. Climate change per se is not
necessarily harmful; the problems arise from extreme events that
are difficult to predict (erratic rainfall patterns and
unpredictable high and low temperatures), and consequently reduce
crop productivity. Vegetables are in general more succulent (have
90% water) and are more sensitive to climatic vagaries. Sudden
changes in temperature coupled with irregular precipitation at any
phase of crop growth can affect the normal growth, flowering,
pollination, fruit setting, fruit development and fruit ripening
can decrease the yield. The irregular precipitation can also affect
the soil salinity and is a major challenge in many vegetable
growing areas. To mitigate the harmful impact of climatic change
there is a urgent need to develop adequate adaptation strategies
for adverse effect of climate change and the preference should be
given on development of heat, cold, drought, flood and salinity
stress tolerant genotypes along with climate proofing through
conventional and non-conventional breeding techniques. Available
evidence shows that there is a high probability of increase in the
frequency and intensity of climate related natural hazards due to
climate change and hence increases the potential threat due to
climate change related natural disasters in the world. This book
(Volume- I) will be basically useful for the researchers and
postgraduate students with current challenges and mitigation
strategies for increasing vegetable production under a changing
climate.

This second volume on the topic will be extremely useful for the
researchers and postgraduate students working on vegetable crops
with a special focus on climate change. Today, the entire world is
suffering from global warming and its consequent, climate change.
This has emerged as the most prominent global environmental issue
and there is an urgent need to mitigate its impact on agriculture.
Over the past 20 years South Asia has had a robust economic growth,
yet it is home to more than one fourth of the world's hunger and
40% of the world's malnourished children and women. Persistent
climatic variability, which results in frequent drought and flood,
is among the major reasons for this phenomenon. Vegetables are in
general more succulent (have 90% water) and more sensitive to
climatic vagaries and sudden changes in temperature, as well as
irregular precipitation at any phase of crop growing, can affect
the normal growth, flowering, pollination, fruit setting, fruit
development and fruit ripening which eventually decreases the
yield. The irregular precipitation also causes the soil salinity
and is a major challenge in many vegetable growing areas. To
mitigate the harmful impact of climatic change there is an urgent
need to develop adequate adaptation strategies for adverse effect
of climate change and preference should be given to the development
of heat, cold, drought, flood and salinity stress tolerant
genotypes along with climate proofing through conventional and
non-conventional breeding techniques, as well as exploiting the
beneficial effects of CO2 enhancement on crop growth and yield.
Available evidence shows that there is high probability of increase
in the frequency and intensity of climate related natural hazards
due to climate change and hence increase the potential threat due
to climate change related natural disasters in the world. At
present protected cultivation and grafted seedlings are also
popularizing among vegetable growers because of the huge scope as
well as, molecular breeding, emerging insect-pests & diseases
and postharvest quality of vegetables under this climate change
scenario. Moreover, underexploited vegetables, perennial vegetable
and tuber crops have a more tolerant ability to climate vagaries
compare to major vegetables which are also discussed in this book.
