IN BRIEF
|
Between tourist attractiveness and the preservation of the living fabric, second homes profoundly transform territories. This article shows why the local population is essential to sustainable tourism: economic continuity all year round, social cohesion, resource sobriety, and local governance. It explores the contrasting effects of holiday homes, highlights inspiring models in France and Europe, and proposes concrete levers—from housing to water management, including sector innovation—to build a balance between hospitality and quality of life.
Why a strong local population makes tourism more sustainable
The presence of residents year-round is the first foundation of a balanced tourism. It ensures a daily life that does not fade away off-season, supports local businesses, secures schools, and maintains public services. Conversely, when the share of second homes exceeds a critical threshold, “cold beds” dominate, seasonality intensifies, and the local economy becomes more fragile, dependent on peaks of attendance.
A permanently inhabited territory better regulates its flows, preserves its identity and heritage, and develops offers that respect hosting capacities. The demand from residents, more regular, encourages investments that are low-impact and long-term, compatible with ecological transition (soft mobility, energy renovation, short circuits). This human network is the condition for a responsible tourism that creates value without exhausting the places.
Economic vitality all year round
Residents stabilize the activities of craftspeople, farmers, restaurateurs, caregivers, and secure jobs in essential services. At dawn, the territory awakens thanks to these professions that keep local life running, as evidenced by these weekend radio shows where, as early as 6:10 am, a morning professional is called, and then at 6:40 am, a mayor to gauge the mood of a municipality. These voices from the ground remind us that tourism prosperity is first fed by a robust residential economy.
Social diversity and cohesion
The cohabitation between visitors, permanent residents, and seasonal workers promotes a respectful culture of hospitality. When the stock of primary residences declines, the risks of gentrification increase, as does dependency on short-term rentals. Conversely, maintaining a diverse local population anchors traditions, smoothes relationships, and encourages frugal practices (sharing spaces, pooling resources, circular economy).
Second homes: contrasting effects on territories
Holiday homes bring income and investments, but they can also intensify land pressure, artificially inflate prices, and undermine access to housing for local households. The challenge is to transform these properties into resources for the community, by stimulating their annual occupancy rate and avoiding vacancy off-season.
Housing, purchasing power, and local workforce
The rise of seasonal rentals captures part of the available stock, complicating life for essential workers (health, education, services) and seasonal workers. Instruments exist: plots under solidarity lease, modulation of housing tax on second homes, framework for tourist furnished rentals or targeted preemption rights. The goal is not closure, but maintaining a balance between hospitality and residential.
Water resource, soil and infrastructure
Summer peaks exert strong pressure on the water resource, sanitation, mobility, and waste management. Anticipation means investing in water sobriety (recovery, reuse, incentive pricing) and smart sizing of networks. The question is raised by the sustainable water management that urges the sector to change scale and practices. Near the coast or in forest areas, like in the Landes engaged in sustainable tourism, adaptation involves fine management of flows and landscape vigilance (erosion, fire risks, biodiversity).
Local governance and dialogues: from the town hall to the morning professions
Territorial governance is crucial. Mayors, intercommunalities, residents, and professionals must co-construct a strategy that reconciles quality of life and attractiveness. Inspiring dialogue formats are emerging: citizen antennas, seasonal workshops, feedback from hosts, and, every weekend, interactive morning shows giving a voice to early-morning workers and elected officials. At 6:10 am, a call to a morning profession; at 6:40 am, an exchange with a mayor: these radio moments convey the essence, the truth of local life.
Tools and public policies
To align second homes and sustainable tourism, several levers exist: quotas for furnished rentals in stressed neighborhoods, obligations for minimum annual occupancy, property charters (renting year-round or in winter season for workers), incentives for energy renovation in exchange for opening to rentals, integration of net zero artificialization goals in urban planning documents (SCOT, PLU), water balances before any accommodation project. Data transparency and local mediation reinforce acceptability.
Inspirational models in Europe and France
Beyond regulations, the sector is evolving. Portugal promotes a more respectful hospitality, nourished by a sense of place and sustainability. The orientation led by VisitPortugal towards a sustainable and meaningful travel shows that a destination can gain desirability while slowing down the race for volumes.
Coastal territories and islands: the case of Sardinia and Corsica
Island spaces, sensitive to overcrowding and land scarcity, are experimenting with balance measures. The analysis of dynamics in Sardinia and Corsica facing mass tourism illustrates the necessity of regulatory tools (schedules, caps, control of water and waste) and a tourism narrative refocused on natural and cultural heritage.
Landes: biodiversity, forests and managed hospitality
In the Landes, the ambition of sustainable tourism is based on the diversity of local environments and know-how. The approach described in Sustainable tourism in the Landes shows how promoting gentle itineraries, protecting ecosystems, and cooperation among stakeholders enhance the resilience of the destinations.
Innovations in the sector
The transformation is also seen in professional meetings. At IFTM Top Resa 2024, the innovations highlighted — data for flow management, low-impact accommodation, decarbonized mobility solutions, water sobriety tools — reflect a sector that equips itself with tools to reconcile welcome and habitability.
Towards a balance pact between second homes and local life
Achieving balance means creating links. Encourage owners to rent to workers in winter, promote high-performance renovation with technical support, share gardens, parking spaces, or workshops, and promote soft mobility to ease pressure in high season. The “reciprocity contracts” — local benefits in exchange for occupancy commitment — structure a win-win pact.
Indicators to guide action
Measuring means being able to act. A few key indicators: share of primary residences, ratio of hot beds/cold beds, occupancy rate of second homes by quarter, water consumption per night, share of soft transport, accessibility to housing (price/m2 relative to median income), and carbon footprint per visitor. These metrics guide adjustments of local policies.
Role of owners and hosts
Each owner can be an actor of sustainable tourism: set more spread-out occupancy calendars, equip with low water and energy equipment, favor local suppliers, and join responsible hospitality charters. Accommodation managers can train teams, sort, measure, and publish their impacts, and engage in community life — all gestures that strengthen the bond between visitors and local population.
