According to the information provided by the Cocoa Research Institute of Ghana and the West African Cashew Alliance (ACA), due to the impact of global climate change, the climate environment on which cashew production depends is constantly changing, and disastrous weather changes adversely affect cashew production in West Africa. Cote d'Ivoire, Guinea Bissau, Ghana, Benin and other countries in West Africa are important cashew nut producers in West Africa. The output of cashew in West Africa accounts for 60% of Africa and 45% of the world. Cashew are drought-loving plants. In recent years, climate change has led to an increase in rainfall, which has had an adverse impact on the growth of cashew. It is necessary to improve the level of agricultural technology and reduce the adverse impact of the disastrous climate on the yield of cashew.
