Marine litter poses a significant threat to marine and coastal ecosystems, impacting wildlife, human health, and local economies. This study examines the public perception of marine litter in Goa, India, focusing on awareness, attitudes, and behaviours. Utilizing a mixed-methods approach, data were collected through structured questionnaires, interviews, and focus group discussions with residents and visitors. The findings highlight gaps in public awareness, varied attitudes towards litter reduction, and the need for targeted educational campaigns and policy interventions. About 65% of respondents were familiar with the term "marine litter," and 78% agreed that it severely impacts beaches and the coastal environment. However, only 60% and 55% of respondents acknowledged severe impacts on tourism and the local economy, respectively. Effective solutions highlighted include education and awareness campaigns (85%), enhanced waste management systems (80%), and promoting sustainable practices (75%). There was strong support (70%) for stricter regulations and penalties. The study recommends innovative solutions such as circular economy initiatives, marine litter monitoring technologies, plastic deposit return schemes, community-based litter banks, public art projects, and eco-tourism programs. These recommendations, if effectively implemented, can foster a more sustainable and engaged community, capable of addressing the multifaceted challenges of marine litter. Collaboration between government authorities, local communities, businesses, and environmental organizations is essential for successful implementation. The study underscores the need for continued research and adaptive management to track progress and refine approaches, ensuring long-term success in combating marine litter in Goa and beyond.
