Natural Disasters And Food Security
Food
security is the condition of having sufficient quqantity of food. It is
pphysical, Economic and Ecological access of food. Hence food security is
directly dependent upon the performance of Agriculture, which in turn depends
on the climatic change. Unfortunately, continuous distruption in climatic
change in recent time have created highly sceptical situations for mankinds to
accomplish food and security its growing population.
Visible impact of change in the climatic
phenomenon are being manifested in the form of extremities of temperature and
precipitation. The most prominent change can be explained by the global warming
, induced by plethora of anthropogenic factors . Their impacts of change in the
natural climatic phenomenon over food security can be seen under following points:-
1. Rise in Sea level:- Due to presistent increase in the average
temperature of the earth, glaciers and ice are melting and water molecules are
expanding. These have threatened almost all the coastal areas of the world and
low lying island, whse fertile land support enormous food production. Rise in
the sea level will permanently submerge such region of the earth , reducing the
cultivation area.
2. Natural Disasters:-
Phenomenon like El- Nino, La Nina are incresing causing warming of
Humboldt current, cold waves in North America, Droughts in south Asia,
Forestfires in South East Asia and many other uncertain climatic conditions highly
adverse for agriculture production. Agriculture of regions especially in developing countries dependent
upon the natural rainfalls are highly affected ,due to untimely, less and even
excessive rainfalls Melting of glaciers
at the mountains may cause massive floods, landslide and destruction of crops
on large scale in tropical regions.
3. Tropical Cyclones:- Frequent and massive cyclones in the east
coast of tropical regions cause massive loss of the life and property including
standing crops, damaging fertile lands ultimately flooding them. There have
been gradual but persistent rise in the tropical Cyclones.
4. Effect On Marine Life:-
Acidification of oceans is increasing gradually affecting any
sources of sea foods. Frequent El-Nino
drastically reduces the fish production in the eastern pacific ocean . There
has been observation in the change in the nature of ocean currents too, which
have impacted the fish production at grand bank and Dogger Bank, well known for
massive fish capturing.
5. Lack of Drinking water:- Drinking water is one of the major
sources of food is getting depleted on daily basis . Glacier and ice , which
are the major sources of fresh water are getting melted and eing lost in the ocean. This causes
scarcity of drinking water.
