Global climate has undergone phenomenal changes over past centuries, leaving behind trails of devastation of all conceivable kinds. Accumulated scientific evidences suggest that these changes are mainly triggered by intensive and wide-spread use of fossil-fuels and various anthropogenic actions, causing green-house effect and consequential global warming. The resulting impacts of these are evident in the forms of melting glaciers, rise of ocean water, natural disasters, loss of lives and biodiversity, to mention a few. The compounded effects of these impacts are manifested, among others, on lower agricultural, aquatic and livestock productivity in general, and the emerging threat on food security and livelihood support systems in particular.

The Book on Global Climate Change and confronting the challenges of food security is written based on this theme. The book exhaustively deals with the emerging issues and the potential threats of global climate change and outlines the broad approaches and strategies to deal with the challenges of food security and human existence at large with due concern and emphasis on global environment and the economy.
