Desmidiales Changing weather is endangering the efficacy of agriculture in regions where feed is scarce many countries. A livelihood of the agricultures were suffered harm as a result of number of extremities caused by environmental factors such as dryness, soaring temperatures, and erratic and heavy amounts of rain, hurricanes and tornadoes, and increasing insect pests. While there is heterogeneity in climatic trends for predicting climate extremes, future climate forecasts revealed a considerable rise in warmth and inconsistent precipitation with increasing severity. (The need to maximize Agriculture that is strategies that are resilient to the climate and technologies for long-lasting production is a reaction to some of the most severe environmental predictions. An interdisciplinary method was a member of this case study to assess the detrimental impacts from warming temperatures on farmer fields. It included 5, an economic model Trade-Off Analysis, Minimum Data Model Method (TOAMD), two crop models (DSSAT and APSIM), and climate models (GCMs). In addition, this study summarizes recent research on climate change's detrimental effects on output from agriculture as well as other major issues, difficulties, and possibilities for sustainable agricultural productivity to guarantee food security.
