Climate change refers to significant, long-term changes in global or regional climate patterns, primarily driven by human activities like burning fossil fuels, deforestation, and industrial processes. It poses a significant threat to global food security, disrupting agricultural productivity and risking the livelihoods of millions. Climatic shifts worsen soil degradation, reduce water availability and increase pest and disease outbreaks, all of which reduce agricultural output. These factors combine to jeopardize food availability, accessibility, and affordability, especially in regions heavily dependent on wheat. To fix these impacts, it is essential to adopt sustainable agricultural practices and implement policies that support farmers in adapting to a changing climate. This book provides complete insights into the field of climate change and its impact on food security, with a particular focus on wheat production. It presents the complex subject of climate change and food security in the most comprehensible and easy to understand language. Through this book, we attempt to further enlighten the readers about the new concepts in this field.
