Climate change causes many conditions that affect societies, countries and even people around the world.Yemen has been suffering from climatic changes that have been affecting people's lives and natural resources for years, and as a result, poverty has spread in Yemen due to successive droughts and floods. According to international organization reports, more than 80% of Yemen's population is food insecure, a third of the population requires immediate food assistance, and more than 3.3 million children are malnourished. The conditions of war and siege have exacerbated Yemen's already dire humanitarian situation.We saw the need to contribute to informing people about the importance and magnitude of the difficulties facing agricultural producers, as well as decision makers and those interested in the subject.Based on this, the main objective of the book's completion was to "raise awareness of the importance of climate change and its impact on the agricultural sector and its impact on food security," and to meet the needs of university students, specialists and those interested in climate change, so that they have an important reference book at their disposal in this regard.
