Climate Change and Food Security: Challenges and Prospects

摘要

The changing trends in the environment and the resultant climate change have perilous impacts upon food security. While the earth's surface temperature has increased, precipitation has decreased significantly across much of the globe in recent years.As such, unprecedented droughts and heavy floods have become common phenomena. Climatic crises further destabilise food security by deepening poverty among poor communities around the world. The need for achieving food security is felt significantly in the recent years due to enormous pressure from the ever-increasing population. Owing to the change in preferences in crop production techniques, several new challenges draw attention to food security. This paper discusses the various challenges to food security, and a critical analysis is made on the biggest challenge, i.e. climate change.
