Climate Change Impact on Global Food Security
The economy of Indian subcontinent is highly dependent on agriculture which makes it vulnerable to issues like climate change and global warming. In India the direct impact of climate change would be effect plant growth development and yield due to change in rainfall and temperature. Global climate changes caused by anthropogenic greenhouse gases will no doubt affect food productivity directly and cause concern for food indirectly as the population increases. Most plants survive in areas with very specific climate conditions, such as temperature and rainfall patterns, that enable them to thrive. Any change in the climate of an area can affect the plants present there, as well as the entire ecosystem.
In India, wheat is the second most important food-grain and is the staple food of millions of people, particularly in the northern and north-western parts of the country. Conditions of growth for wheat are more flexible than those of rice. The report said climate change had already cut into the global food supply. According to different researches, it was observed that global yield was decreasing chiefly for wheat.
There might be world’s food crisis, where 1 billion people are already remain hungry and further 2 billion people will be affected by 2050, is set to worsen as increasing heat waves reverse the rising crop yields seen over the last 50 years, according to new research. In spite of this progress, according to the World Bank, 702 million people still live in extreme poverty and, according to this year’s report on the State of Food Insecurity in the World (SOFI), 793 million people are undernourished.
