Assessing the Financial Implications of Climate and Environmental Risk in Salt Manufacturing in Thoothukudi (SDG 13)
Summary
Researchers analyzed primary data from salt manufacturers in Thoothukudi, India, finding that climate variables — particularly unseasonal rainfall and extreme weather — significantly predict revenue volatility and operational cost escalation, while emerging microplastic contamination poses additional threats to product marketability in this SDG-13-relevant sector.
Abstract: This study examines the financial impact of climate and environmental risks on salt manufacturing units in Thoothukudi, a major salt-producing region in India. The research adopts an analytical approach using primary data collected from salt manufacturers and workers. Statistical tools such as descriptive analysis, correlation, and regression were applied to evaluate the relationship between climate variability and financial performance indicators. The findings reveal a strong positive relationship between climate risks—particularly unseasonal rainfall and extreme weather events—and revenue volatility, operational cost escalation, and infrastructure damage. Regression results indicate that climate-related variables significantly predict financial instability in the sector. The study highlights that environmental risks such as pollution and microplastic contamination also pose emerging threats to marketability. The research concludes that climate risk is not only an environmental concern but a critical financial determinant, emphasizing the need for adaptive strategies aligned with SDG 13 (Climate Action).
