In the present era, many developed countries blame to the
Asian countries for increase in the global temperature due to rice cultivation.
Agriculture contributes approximately 13.5% green house gasses emission at the
global level. The maximum area of rice cultivation is in India at global
level. In our country rice is being cultivated on an area of 44.0 million
hectares (FAI, 2007-08).
Rice is not only a food for more than half of the
population of India
but it is a base for nutritious food. Rice has an important place among the
cereal crops. Rice is being cultivated in almost all the states of India, as a
main crop. India
is one of the main producers and exporter of aromatic rice in the international
market. Presently, farmers are facing serious problems pertaining to shortage
energy, increase in agricultural input prices and global
climate change. These problems automatically create many other problems. Many
problems are arising due to faulty irrigation system and indiscriminate use of
chemical fertilizer in the cultivation of rice.
Traditional flooding irrigation system and more than
required fertilizer uses for the cultivation of rice has become a serious challenge
for the environment degradation. Consequently, by the cultivation of rice, the
green house gasses emission like methane (CH4) and nitrous oxide (NO2) concentrations
increase in environment, resulting such ill-effects leading to climate change.
change in the climate is affecting not only the human
beings but also other mammals and living beings health adversely. Agricultural scientists,
subject matter specialist and farmers of our country need the alternatives for
these ill full methods. Therefore, it will lead to lesser green house gasses
emission from the rice fields and have lesser harm to the environmental health
/ degradation and the
same time lesser cost of production for rice cultivation
so that the future generation will not get only sufficient and quality food along
with safe environment to solve the climate change problems. It is better to
control pollution at its source, which is a better option. We need to develop
improved agricultural technologies, which not only maintain the clean
environment but also will continuously improve it. We need to manage irrigation
and chemical fertilizer judiciously for the cultivation of rice. In this regard
System of Rice Intensification (SRI) technique, aerobic
rice cultivation, value added nitrogenous fertilizer and bio-fertilizers can play
a crucial role. Therefore, we need to make these technologies popular among the
farmers. So that use of these conserved technologies will lead to the better
environment and rice cultivation may be more profitable crop.
