This paper examines current climate predictions and how climate shifts in various regions may impact global agricultural production and food security. The purposes of this paper are to (i) outline the notion of food systems, their relation to food security, and links to climate change; (ii) explore the vulnerability of food systems to environmental change; (iii) examine some prospects for adaptation of food systems in response to climate change. It was in September 2013 that the National Food Security Act (NFSA) was enacted. Though a landmark legislation, and despite its life-cycle approach, the NFSA falls short of realizing this objective due to lack of universalized coverage, concerns exist about the inordinate delay in implementing the law as the tasks of framing rules and identifying beneficiaries. Problems lie with the PDS scheme of the Act, suggestions for the same is given. .It concludes that agricultural practices will need to be modified or adapted to correlate with anticipated shifts in weather patterns if food security is to be maintained into the future. The first chapter talks about climate change, food security, and food systems. It further explains the interrelationship between climate change and food security. The second part deals with analyzing the effects of climate change on Indian agriculture. The third part talks about the National Food Security Act, 2013 followed by its shortcomings in the fourth section. The article closes by discussing various adaptation efforts that could help to maintain Indian food security.”
