The issue of climate change and its impact on the productivity of agricultural crops has become of great importance and requires studying it at the local and global levels; To identify the most important negative or positive results. Egypt is expected to be one of the most countries affected by the impact of climate change; As a result of expected risks on agriculture, agricultural land, water supply and food security. It is also expected that the temperature will rise by about 3.5 degrees Celsius by 2050; Which will have an impact on the feddan productivity of most agricultural crops, as well as a reduced quality and quality of production, also the Egyptian food security. For this reason, the research aimed to study the current situation of each of the cultivated area, productivity and production of the most important crop in the fodder and sugar agricultural group, namely clover and sugar cane . In addition to studying the impact of the dimensions of climate changes represented in (maximum and minimum temperatures, relative humidity and precipitation) on their productivity in the new and old lands in the governorates of Egypt.
It was found that clover cultivations were concentrated in the old lands, despite the superiority of their productivity in the new lands; Where the average productivity during the last 3 years was about 30.90 and 35.07 ton/ feddan, respectively.
