Global agricultural productivity is seriously threatened by the growing threat of climate change, which is principally manifested in rising sea levels. This research article undertakes a thorough evaluation of the available literature and analyses secondary data to explore the relationship between sea level rise (SLR) and agricultural productivity in depth. The study provides a more nuanced understanding of the various geographical effects of SLR on agriculture by closely examining global impacts with a specific focus on multiple case studies. Our assessment of the literature analyses the corpus of information already available on SLR, climate change, and how these factors affect agricultural practises. It points out a significant gap in the literature currently available: the absence of thorough, multi-country comparative studies. We close this gap by analysing the global and country-specific implications of SLR on agriculture by secondary data analysis, taking into account elements such crop production variations, modifications to agricultural techniques, and adaptive tactics. The results highlight the significant and frequently distinct effects of SLR on agricultural industries across several geographic contexts. They emphasise the pressing need for effective, region-specific adaptation measures to protect our global food system from the effects of climate change. This study also provides a platform for researchers and policymakers to engage in more focused and successful tactics, emphasising areas in need of immediate attention. This study makes a significant contribution to the ongoing conversation about climate change and food security by shedding light on the intricate relationships between agricultural productivity and climate-induced SLR.
