5.12 - Unsustainable Tourism
The concept of carrying capacity in tourism
Carrying capacity is a critical concept in managing tourism, as it determines the maximum level of visitor activity a destination can handle without negative consequences.
Types of carrying capacity in tourism
- Physical carrying capacity - Refers to the actual space available for tourists, such as the number of parking spaces.
- Ecological carrying capacity - Indicates the level of use an environment can endure before suffering damage.
- Perceptual carrying capacity - Relates to the level of crowding a tourist is willing to accept before feeling that a destination is too busy.
Tourism challenges in Venice as an urban hotspot
Venice, a historic city covering 700 hectares, faces significant challenges due to unsustainable tourism growth. Its iconic status and protected architecture draw millions of visitors, but this creates social, economic, and logistical issues for local authorities.
Visitor numbers and carrying capacity limits in Venice
- Optimum capacity - Research suggests Venice can sustainably accommodate 9,780 tourists in hotel stays and 1,460 in non-hotel accommodations.
- Seasonal peaks - Visitor numbers surge in summer and at weekends, with an average of 37,500 day trippers per day during peak months like August.
- Suggested maximum - A limit of 25,000 visitors per day has been proposed to prevent overcrowding and preserve the city’s infrastructure.
Social and economic problems caused by tourism
- Congestion issues - High visitor volumes lead to overcrowding.
- Resource competition - Scarce resources are strained by the influx of tourists.
- Day tripper impact - Day trippers, who contribute less to the local economy compared to overnight visitors, are increasing, while residential tourism declines.
Management strategies for day trippers
- Restricted coach access - Unauthorised tour coaches are barred from the main terminal to limit day tripper numbers.
- Entry fees and gates - Gates have been installed around the city, with charges for entry to control visitor flow.
Impact of cruise tourism
- Cruise liner statistics - In 2015, over 650 cruise ships docked in Venice, carrying more than 2.2 million passengers.
- Economic shortfall - Despite high passenger numbers, tourism revenue dropped by approximately €300 million, as cruise visitors rarely stay in hotels, eat large meals locally, or hire local guides.
Tourism issues in the Llanthony Valley, Brecon Beacons, as a rural hotspot
Located in the Brecon Beacons National Park in South Wales, the Llanthony Valley exemplifies the challenges of rural tourism. Close to urban centres like London and Birmingham, it attracts many visitors, but their presence often brings more disruption than benefit to the local community.
Negative impacts of tourism in the Llanthony Valley
- Disruption to local life - Tourists often block farm gates with vehicles, hindering farmers from moving livestock or machinery.
- Limited economic benefit - Many visitors are on short drives through the area, contributing little to the local economy.
- Lack of engagement - Tourists frequently gain minimal understanding of the community, landscape, or cultural heritage.
Environmental impacts of tourism
Tourism, while economically significant, often places considerable stress on the environment through various activities. These impacts can alter ecosystems, degrade natural resources, and affect both human and ecological health.
Key environmental stressors and responses
| Stressor activity | Stress caused | Primary environmental response |
|---|---|---|
| Permanent environmental restructuring | Restructuring of local environments through major construction like urban expansion, transport networks, and tourist facilities (e.g., marinas, ski-lifts) | Changes in habitat, species populations, human health, and visual quality of the landscape. |
| Generation of waste | Pollution from tourism and transport activities, including emissions, effluent discharge, solid waste, and noise (e.g., traffic, aircraft). | Decline in quality of air, water, and soil; negative effects on organism and human health. |
| Tourist activities | Physical damage from activities like skiing, walking, hunting, and trail-bike riding, leading to trampling of vegetation and soils. | Alterations in habitat and reductions in species populations. |
| Effect on population dynamics | Seasonal increases in population density due to tourism growth. | Congestion and heightened demand for natural resources like land, water, and energy. |
