‘Cemented’ coastal zones on Crete: focus on tourist areas.
High density of impermeable surfaces on the north coast of Crete
Research from the University of Thessaly highlights significant levels of impermeable surfaces along the northern coastline of Crete. This urbanisation contributes to the degradation of coastal ecosystems, raises concerns about flooding, and is linked to increased energy demands.
The study has placed a strong focus on tourist areas in Crete, revealing concerning findings. A large disparity has been observed between the northern and southern parts of the island.
In particular, major urban centres have more than 50% of their land sealed. This information was shared by Professor Apostolos Lagaras from the Department of Spatial Planning, Urban Development, and Regional Growth at the University of Thessaly during an interview on SKAI Crete radio.
According to a recent report by the Intergovernmental Panel on Climate Change (IPCC), managing urban sprawl is a key factor in adapting to climate change and ensuring sustainable land use.
It is crucial to recognise that the relationship between urban expansion and climate change is reciprocal.
On one hand, the rapid growth of urban land use contributes to climate change by diminishing the capacity of natural ecosystems to absorb carbon dioxide. This development is associated with higher greenhouse gas emissions, as well as increased demand for energy, infrastructure, and natural resources.
Conversely, low-density and scattered development along coastlines makes settlements and economic activities particularly vulnerable due to high concentrations of population and infrastructure in areas susceptible to the effects of climate change.
The research indicates that the pattern of linear tourist spread along the coastline leads to cumulative overcrowding in tourist destinations, notably in islands with high visitor volumes such as Crete, Corfu, Rhodes, Mykonos, Santorini, Kos, and Zakynthos.
Coastal areas projected to experience more frequent drought periods are located in Crete, the southern Peloponnese, and surrounding islands.
This trend illustrates the complex interplay between human activities and natural environmental changes, underscoring the urgent need for sustainable planning and management approaches.
It is essential to address these concerns proactively, as the impact of urbanisation not only threatens local ecosystems but also poses long-term risks for residents and visitors alike.
And with the continuing effects of climate change, finding a balance between development and ecological preservation is increasingly critical for the future of these regions.
Considering these challenges, it becomes necessary for policymakers, urban planners, and stakeholders in tourism to collaborate on developing strategies that mitigate the negative consequences of urbanisation.
By prioritising sustainable practices, they can ensure that both the natural environment and the economy thrive in the face of ongoing pressures.
The cemented coastal areas of Crete
Environmental and climatic conditions are serious concerns regarding the future of coastal developments. Maria Kozyraki, the Secretary General of the Decentralised Administration of Crete, expressed her worries about the impact of construction near water bodies through social media. She highlighted a critical issue: those who build on the shoreline or in riverbeds may face dire consequences.
Professor Apostolos Lagaras from the Department of Spatial Planning and Urban Development at the University of Thessaly has examined a stretch of coastline extending two kilometres along the Greek coast, using data from European organisations.
His findings reveal alarming levels of impermeability along these shores, primarily caused by the use of concrete that prevents water drainage.
Most affected areas are located in northern Crete, especially around Ierapetra. The prevalence of these impermeable surfaces is notably high in Heraklion, Rethymno, Chania, and Hersonissos.
New areas at risk of environmental issues include nearly all regions in Lasithi Prefecture. A map highlighting these areas also reveals regions east and west of Ierapetra, marked red to signify high levels of impermeable surfaces that are stagnant. Yellow indicates areas with over 10% impermeable surfaces on the Lasithi coast that are experiencing increases, while green marks a small section at the eastern end of Sitia that has low impermeable surface levels.
The regulations regarding the minimum distance for building from the shore are also critical.
Currently, residential structures must be at least 30 metres from the shoreline, while hotels are set at 50 metres.
Professor Lagaras believes that increasing this minimum distance to 100 metres, as suggested by the Barcelona Protocol, would significantly enhance coastal landscape protection for future generations.
Understanding these developments is crucial for residents and policymakers tasked with preserving these vital coastal ecosystems. The pressing need for action has been articulated through various reports detailing the situation of Greece’s coastlines.
Continued monitoring and thoughtful legislation could safeguard these environments from further harm.
Cement has a significant impact on coastal areas. The heavy use of this material has contributed to a concerning increase in impermeable surfaces, making it nearly impossible for water to seep into the ground.
As certain regions continue to face these challenges, the call for more sustainable building practices grows louder.
To combat these environmental challenges, a concerted effort among builders, authorities, and environmentalists is necessary.
Implementing stricter regulations can be a step towards mitigating further damage to both the landscape and the ecosystem.
As suggested by various experts, careful planning and adherence to recommended practices can protect coastal communities and their surroundings from the adverse effects of climate change.
Communities situated near the coast must adopt practices that prioritise environmental sustainability.
This includes limiting construction within vulnerable areas, maintaining setbacks from the shore, and utilising materials that pose less risk to the environment.
In addition, ongoing education about ecological impact can empower local communities to make informed decisions regarding coastal development.
Frequently Asked Questions
What are the key coastal reinforcement projects in central Crete’s tourist locations?
Central Crete is currently undertaking several significant coastal reinforcement projects.
These include the construction of breakwaters, beach nourishment, and the installation of protective barriers to reduce the impact of waves and storms. These efforts aim to safeguard popular tourist areas and preserve their natural beauty.
How is Crete addressing coastal erosion in tourism areas?
Crete is tackling coastal erosion through a combination of strategies.
These include both soft and hard engineering solutions. Soft solutions involve adding sand to beaches, while hard solutions focus on building structures like sea walls to halt the erosion process effectively.
What steps are being taken to maintain the sustainability of beaches in tourist areas of Crete?
To ensure beach sustainability, Crete is implementing various measures.
These include regular monitoring of beach conditions, controlled sand replenishment, and habitat restoration projects. Additionally, promoting responsible tourism practices contributes to long-term beach health.
Can updates be provided on the advancement of coastal enhancement in central Crete’s tourism sectors?
Yes, updates on coastal enhancement efforts are regularly published by local authorities.
Recent reports indicate that several projects are ahead of schedule, with initial phases focused on structural improvements. Community engagement is also being encouraged to involve residents in the process.
What is the expected impact of coastal reinforcement on tourism in central Crete?
The coastal reinforcement initiatives are anticipated to positively influence tourism in central Crete.
By increasing the resilience of beaches and coastal areas, they are likely to attract more visitors. This can lead to economic growth for local businesses and enhanced visitor experiences.
How does coastal reinforcement comply with environmental regulations in Crete’s tourist districts?
Coastal reinforcement projects in Crete are designed to align with environmental regulations.
Authorities conduct environmental impact assessments to ensure that the initiatives do not adversely affect the local ecosystem.
Continuous collaboration with environmental groups also helps to maintain ecological balance during development.
