The present era is third
industrial revolution and the world is going towards development, but the cost
of this development is the environmental degradation. One of the most dangerous
climate changes is due to global warming. Global warming means increase in the
average temperature of the Earth.
Intergovernmental Panel on
Climate Change (IPCC) stated that the increase in global average temperature is
very likely due to anthropogenic greenhouse gas concentration. This has
adversely affected
the negative impacts on crop production, which gives a significant economic
loss to us. Loss of food and water is one of the immediate threats by global
warming. Crop productivity decreases globally for even small changes in average
temperature of 1-3°C.
Local adverse effects also hit the aquaculture
and fisheries industries directly or indirectly. Climate variability and their
effect on environment severely compromises food production and yields decreases
in some regions upto 50% by 2025.
