There has been a widespread and well-discussed issue around the world about the concept of climate change. This study paper explores what the effect of climate change is on food security in India with Karnataka as a case in point. The very first section reflects essentially around the consequences of climate change on the fundamental evaluations of food security and domestic wellbeing in India. The research employed secondary analysis of data. The key result is that states who haven't yet suffered flooding and droughts have already started to encounter such disasters and to undergo severe weather conditions, negatively impacting small and macro-level food security crises. It is proposed that the country, together with all the other stakeholders, adopt a proactive and systematic solution to the reduction and mitigation of consequences of climate change on sustainable economic growth
