With the increasing population, by 2030, the population of India will have seen an unprecedented rise of 1.43 billion and require food grains of around 311 million tones. Of the total area, nearly 5% of the area in India is affected by soil salinity. It is said that about 10% of soil is salinized every year. At this rate, 50% of the land area will be salinized by 2050.These repercussions challenge us to expand the area under cultivation or to increase the yield per unit area to maintain food security and sustainability. In order to meet the growing demands of the increased population, two major approaches can be met. Firstly, the available area under cultivation must be increased, which can be done by the reclamation of various problematic soils and making them suitable for cultivation. The second and holistic approach is to employ various biotechnological and breeding aspects in the development of resistant varieties surviving the harsh and unfavourable environment and showing no subsequent reduction in the yield parameters. For this, one must understand the various physiological aspects of tolerance for screening the elite varieties suited for a particular ecosystem or environment. Thus, the present study vividly explains the various physiological aspects of salt stress on rice. Employing these techniques, one can screen superior genotypes resistant to various stresses, thus keeping the Malthus predictions at bay.
