Anthropogenic factors such as the spread of non-degradable waste and sewage disposal can significantly influence the nesting behaviour of Olive Ridley Turtles. To assess these anthropogenic threats to olive Ridley turtle nesting sites on the Ratnagiri coast of Maharashtra, a study was conducted during the breeding seasons of 2019-20 and 2020-21. Beach profiling and non-biodegradable waste ground cover were examined across 11 beaches in the Ratnagiri District. The study revealed that many resorts discharge their wastewater and non-biodegradable solid waste directly onto the beaches. Additionally, ocean currents contribute to waste accumulation during ebb and flow. Consequently, female turtles tend to avoid these sewage-prone beach areas for nesting. While non-degradable ground cover litter was present, it did not show a significant association with nesting density. Therefore, to mitigate these anthropogenic impacts on nesting Olive Ridley sea turtles, the implementation of strict sewage and waste disposal regulations is a crucial and immediate step towards protecting these vulnerable nesting sites along the Ratnagiri coast.
