EXPLORING RELATIONSHIPS BETWEEN CLIMATIC VARIABILITY, RIVER WATER LEVELS, AND CROP PRODUCTIVITY TRENDS IN NORTHEASTERN BANGLADESH

Abstract

Trend analysis serves as a pivotal tool for monitoring, forecasting, and evaluating the occurrences and values associated with specific events. Concurrently, climate change manifests as a persistent trend in climatic variables, exhibiting continuous fluctuations in average values over extended timeframes. Escalating climatic and meteorological extremes have engendered global concern due to their severe impacts on ecosystems, economies, and human livelihoods. This study explores the variability and destructiveness of these events, especially with respect to agricultural production. Notably, the likelihood of decreased cool days and nights, intensification of heavy precipitation, and prolonged droughts has surged since the 1970s. The planet is undergoing a transformative shift, marked by surges in temperature, precipitation variability, and inundation incidents. Scientific inquiries underscore an impending global temperature increase of 1.4 to 5.8 °C by 2100, accompanied by an average sea level rise of 10 cm during the same period. This analysis delves into the intersection of trend analysis and climate change, aiming to enhance our understanding of their intricate dynamics and implications.
