The tourism industry is among the fastest growing globally, with an oversized increase in travelers, businesses, and activities. Besides tourism’s considerable economic benefits, its adverse social and environmental impacts are rising, including the depletion of natural resources, pollution, loss of authentic local cultures, seasonal pressures, and more. Tourism, particularly the nautical sector, largely depends on natural and social capital, jeopardizing them through continuous growth and expansion. For instance, it vastly pressurizes the marine environment and communities during peak season, resulting in expanded pollution, water deficit, traffic congestion, and decreased quality of life. However, the nautical sector generates considerable jobs, revenues, and economic growth for coastal communities worldwide. Numerous coastal economies depend solely on tourism, with nautical ports playing a significant role in the sector. Many nautical ports focus on sustainable development and seek degrowth strategies. This chapter uses the value chain to investigate degrowth solutions in nautical tourism. It creates degrowth value chain framework for nautical ports that considers sustainable solutions across their primary and support activities. The proposed framework is based on secondary data related to the ports’ business practices, requirements of eco-certificates, sustainable development goals, and green innovations in the nautical sector.
