Pulses, also known as the poor man's meat and the rich man's vegetable, contribute to worldwide nutritional security. The Food and Agriculture Organization (FAO) has designated 2016 as the "International Year of Pulses", noting protein inadequacy as a global issue. According to the United Nations, the present global population of 7.6 billion people will grow to 8.6 billion in 2030, 9.8 billion in 2050, and 11.2 billion in 2100. Climate change and agriculture are inextricably linked, and both occur on a global scale with significant regional and zonal variation. Crop yields will be negatively impacted by climate change by the end of the twenty-first century, particularly owing to temperature changes. High temperatures during the reproductive stage cause flower drop, male sterility, anthesis impairment, and a shorter grain-filling duration. The geographic variability of climate variables, particularly downfall over colourful regions, shows a great deal of variation in both place and time. Drought, often spelled dearth, is a prolonged lack or insufficiency of rain that results in a significant hydrologic (water) imbalance and, as a result, water shortages, crop damage, sluice inflow reduction, and groundwater and soil humidity reduction. Temperature and rainfall are the two most essential climatic elements that influence crop growth, development and yield. Crop phenology is influenced by temperature; therefore fluctuations in temperature during the growing season affect crop length. Reduced rainfall causes humidity stress, which affects physiological processes, ultimately lowering production.
