Adaptation to droughts in wetlands of Attica Region, Greece

Adaptation to droughts in wetlands of Attica Region, Greece

The Attica region in Greece is working to gradually implement an adaptation strategy and action plan for the conservation of wetlands, a highly vulnerable ecosystem that suffers from increasing droughts. The improved scientific evidence on the benefits provided  by wetlands is creating the conditions for their legal designation and adaptive management.

The strategy and action plan for the wetland ecosystems in Attica Region (Greece) were developed in the OrientGate project by the Environmental Department of Attica Regional Authority with the scientific support of the Greek Biotope Wetland Centre (EKBY).

Based on projections of future drought episodes, as well as on information from operational programmes and actions that are in progress or scheduled by various institutions and organisations, the strategy set the vision and commitment to conservation and adaptation to climate change of the Attica’s wetlands to increase its resilience and reduce biodiversity loss, while making better use of ecosystem services.

The strategy is built on seven axes under which measures with specific priority actions have been determined in the Attica Wetland Action Plan. This strategy also includes some over-arching elements: sustainable management and restoration of wetlands; their interconnection in a “green belt”; the evaluation of the services provided; awareness raising and environmental education in biodiversity and climate change, and citizen participation. The Attica Regional Authority drafted a road map to promote the implementation of selected actions of the Plan under the National Strategic Reference Framework 2014-2020, the new Regional climate change adaptation plan (RePACC, 2022-2028) and the Operational Program of Attica Region 2021-2027.

From September 2015 to April 2017, a project entitled “Improving knowledge and increasing awareness for wetland restoration in Attica Region” implemented some priority actions, while the EU funded SWOS Project has developed new knowledge for monitoring of wetland ecosystems.

Case Study Description

Challenges

The Region of Attica is called on to combine the needs arising from human overpopulation, various human activities and often competitive land use through the proper and sustainable management and protection of the natural environment. Wetlands constitute a significant element of the natural environment. They are important ecosystems for the conservation of different species. Moreover, they provide cultural ecosystem services, as areas for recreation, archaeological and cultural sites. They also provide regulating ecosystem services (by mitigating droughts and acting as buffer against increasing floods) and provisioning ecosystem services (by storing water and ensure food supplies). In this way wetlands protect human lives and their economic activities (e.g. agriculture, tourism, fisheries). Within the territory of the Region of Attica, there are still more than 100 wetlands including: streams and their estuaries, coastal marshes and lagoons, lakes and constructed (man-made) wetlands. They now constitute “high biodiversity islands” within a broadly degraded environment and offer the opportunity to stay in touch with nature to the inhabitants of the Attica Region .

Climate Change is expected to exacerbate existing impacts coming from human activities, putting additional pressure on these habitats. The OrientGate project (2012-2014), co-funded by the EU South East Europe Transnational Cooperation Programme, provided some first insights on the vulnerability to drought of this region. According to the project results, drought vulnerability is expected to increase by 2100 from low to moderate levels under the IPCC A1B emission scenario (medium/high emission scenario, close to the more recent RCP 6.0 scenario). A decrease in precipitation was also projected in autumn across the region by 2100 under the same scenario, while slight increases were projected in spring. More recent data suggest that global warming levels higher than 1.5° to 2°C will generate increased pressure on water resources of the Mediterranean region. The probability of more extreme and frequent meteorological, hydrological and agricultural droughts will likely increase substantially, with 5 to 10 times more frequent droughts in many Mediterranean regions (First Mediterranean Assessment Report, 2020). This phenomenon is expected to have serious impacts on Attica wetlands as most of them are rain-fed. Further, due to the synergy of deteriorating drought conditions and anthropogenic interventions, most of Attica's wetlands are expected to suffer moderate to high impacts. The Regional Plan for Adaptation to Climate Change (RePACC) includes an updated vulnerability assessment/risk analysis in several sectors including biodiversity/forestry ecosystems and water resources/floods. They apply RCP4.5 and RCP8.5 scenarios for two future periods (2031-2050 and 2081-2100), confirming the urgency of taking actions to save wetlands from climate change.

At the same time, findings show that the agencies involved in the conservation of Attica wetlands have a medium-level adaptive capacity. In particular, there is inadequate knowledge of wetland ecosystems and their services, a lack of experience in the use and interpretation of climatic parameters, a low degree of networking and exchange of experiences and good practices, medium-level operational capacity of the competent agencies and availability of funds for the implementation of adaptation measures. In parallel, however, the civil society in the Attica region is gaining a high level of understanding of the role played by wetlands in the quality of life.

For the purpose of conserving the wetlands of Attica, the OrientGate project delivered an adaptation strategy and an action plan. These policy documents are expected to reduce the impacts of the combined effects of anthropogenic interventions and climate change on wetlands. They are also expected to improve the capacity of various stakeholders to cope with climate change.

Objectives

In Attica, more than 100 wetlands have been recorded, which include streams and estuaries, coastal marshes and lagoons, lakes and artificial wetlands. Their importance lies in their ecological and conservation values, as well as ecosystem services for human well-being. Strategic priorities for improving the natural environment and the life quality of citizens, are: to preserve and/or restore wetlands, to improve their ecological connectivity through a “green belt” and to support their use for recreation. The goal of the OrientGate project was to produce a climate change adaptation strategy and an action plan, which: (i) involve monitoring and assessing of the environmental quality of wetland areas in Attica Region, (ii) study drought deterioration in the future and (iii) put in force the implementation of a series of measures that reduce regional vulnerability of wetlands to climate change.

Solutions

The climate change adaptation Strategy prepared within the Orientgate project, is built on seven axes. For each of them, several measures with different priorities have been established in the “Attica Wetland Action Plan”. The central concept of these actions is the preservation and restoration of wetlands from the impacts of climate change. Healthy wetlands can in turn help protect against drought and extreme events, providing an important resource for adaptation.

  • AXIS I - Improvement of knowledge for Attica wetlands and the effects of climate change: Measure Ι-1: Continuous enrichment of knowledge about the wetlands of Attica, as “high biodiversity islands” and as integral elements (green and blue infrastructure) of urban and extra-urban space; Measure Ι-2: Assessment and periodic updating of climate indicators for drought/water scarcity and floods, with climate prediction models, for the territory of the Attica region, and investigation of the impacts on biodiversity; Measure I-3: Ensure access to data and information on wetlands in Attica and climate indicators, and monitor the implementation of the Strategy.
  • AXIS II - Conservation and restoration of Attica wetland ecosystems and their services and adaptation to climate change: Measure ΙΙ-1: Delineate wetlands and designate protected areas; Measure ΙΙ-2: Protect, guard, conserve and restore; Measure ΙΙ-3: Conserve and manage sustainably wetlands of the Natura 2000 network.
  • AXIS III - Sustainable use of water resources: Measure ΙΙΙ-1: Prevent and abate industrial pollution.
  • AXIS IV - Land use regulations: Measure ΙV-1: Promote the concept of compact and non-polluting city.
  • AXIS V - Information, awareness, and ecotourism: Measure V-1: Strengthen public information and awareness programs for wetlands in Attica and climate change adaptation; Measure V-2: Education for wetlands and climate change adaptation; Measure V-3: Highlight the wealth of wetlands in Attica, improve recreation and ecotourism opportunities.
  • AXIS VI - Improvement of adaptive capacity in regard to wetland conservation and management: Measure VI-1: Strengthening public administration and local government in the decision-making process and the implementation of policies, measures and legislation on wetlands.
  • AXIS VII - Integration of wetland conservation in enterprises: Measure VIΙ-1: Promote innovation and entrepreneurship in wetland conservation, encourage businesses to adopt practices and activities that benefit wetland conservation and avoid practices and activities that have a negative impact on wetlands.

From September 2015 to April 2017, some progress towards the implementation of the action plan (Measure I-I of the Attica Wetland Action Plan) was achieved within the project “Improving knowledge and increasing awareness for wetland restoration in Attica Region”, funded by the EEA and Norway Grants program for integrated management of marine and inland water resources. The project is expected to increase knowledge and awareness on Attica wetlands as water related ecosystems that face serious environmental problems and biodiversity loss.

Main project results were an improved access to environmental information necessary to protect and restore wetlands, with increased knowledge and awareness on the value of wetlands for climate change adaptation. In particular, the scientific documentation for the identification and delineation of 50 wetlands was prepared, accompanied by the analysis of biodiversity, major threats and proposals for rehabilitation.

 

Wetland information was stored in a freely accessible web database. A web-GIS platform was developed to show various spatial data, while an online atlas displays images and stories of Attica wetlands, describing their environmental value and the conservation measures in place.

For four water bodies, a detailed assessment of water quality, wetland conservation status and water management needs was prepared: Vourkari (coastal wetland in Megara municipality) and Koumoundourou Lake (in Aspropyrgos municipality) in west Attica region, the mouth of Pikrodafni Stream (in south Athens) and National Park Schinias (coastal wetland part of the EU Natura 2000 network) in east Attica region.

Moreover, a research study was elaborated in the frame of Horizon 2020 SWOS Project (Hatziiordanou et al. 2019). It revealed the potential of wetlands to act as key landscape features (i.e. stepping stones) that can improve the connectivity and climate resilience of the Natura 2000 network of Attica Region. Research results could be helpful to prioritise conservation and restoration in the context of the EU biodiversity policy demand for a coherent Natura 2000 network and for achieving no net loss.

As part of the activities to implement the Measure II-1 of the Attica Wetland Action Plan, following the environmental characterisation, the Vourkari wetland was designed as “Regional Park” by a Presidential Decree, in March 2017. Moreover, the official delineation of boundaries of 15 wetlands was completed and incorporated in the national legislation (law 4559, August 2018), covering a total area of more than 460 ha. The law bans any building permits and any activity that degrades the ecological status of wetlands, including water draining. This support wetland preservation from the combined impacts of climate change and human activities.

In addition, environmental awareness raising initiatives and training events were organised to create a collaborative space where different stakeholders contribute to an improved management of wetlands in a future looking perspective dominated by climate change (see the section on stakeholders involvement).

Additional Details

Stakeholder Participation

From the beginning of the OrientGate project, Attica Region engaged a wide range of stakeholders and implemented several actions to enhance the awareness on the value of wetlands, also in a climate change context, through media, workshops, training seminars, and information meetings. Thus, the wetland adaptation strategy and plan followed a wide participative process. The Attica Regional Authority drove the entire process and drafted a road map to promote the implementation of the actions of the plan, while the Greek Biotope Wetland Centre provided the scientific support. The collaboration expanded to central, regional and local services and authorities, research agencies, environmental organizations and citizens. Although they participated to a minor extent, they provided their knowledge, experience and practices within the adaptation process.

Concerning the actual implementation of the Action Plan, the relevant authorities are the central government for the legislation-related issues and the local administrations (Attica Region and its municipalities) for the implementation of the interventions. For some of the Attica wetlands, which are characterised as Natura 2000 sites, the Management Body of Schinias Marathon National Park, Hymettus and South-East Attica is also a relevant authority for the implementation of the Action Plan

At the end of 2014, a training seminar “Adaptation strategy for Attica Wetlands: The assessment of wetland vulnerability index” and an open dissemination event were held. During the seminar, around 30 participants from public services of Attica Region, NGOs, research institutes, and participants from other countries (Serbia and Romania), received hands-on training on the Wetland Vulnerability Indicator assessment methodology. During the dissemination event, around 80 participants received information on the expected increase of  Attica wetland vulnerability to drought and on the adaptation action plan. Participants came from local and national authorities, NGOs, research institutions, and stakeholders from other sectors, such as archaeologists.

In 2015, Attica Region carried out a satellite event of the Green Week 2015 “Raising support to restore the wetland of Brexiza, in the Region of Attica, Greece”. During this event, almost 90 visitors experienced the biodiversity of Brexiza wetland and the important archaeological site of the Roman great temple of the Egyptian gods. This event opened the dialogue on Brexiza wetland restoration and biodiversity protection and on the implementation of the adaptation action plan for the Attica region.

All these events were organized by Attica Region and scientifically supported by the Greek Biotope Wetland Centre. Participants were very much motivated and showed strong interest to increase their knowledge and capacity in order to become capable to take action towards climate change adaptation and wetland conservation.

The Attica Region was also one of the main promoter of the project funded under the EEA and Norway grants (Improving knowledge and increasing awareness for wetland restoration in Attica Region). The regional government collaborated with other partners such as the Goulandris Natural History Museum - Greek Biotope / Wetland Centre, the Management Body of National Park of Schinias Marathon as well as the donor partner (the Norwegian Institute of Bioeconomy Research -NIBIO). Several public events were organized to demonstrate project findings and results.

Other activities of stakeholders participation were done for the preparation of the Regional Plan for the Adaptation to Climate Change (RePACC) of Attica  which assesses the vulnerability and analyses climate change  in several sectors (agriculture, fisheries, forestry, water resources, etc). A video conference in  July 2020, specifically focused on the biodiversity sector, including Attica’s wetlands, involving the major public administration stakeholders and the scientists who worked in that area. Attica’s RePACC and its Strategic Environmental Impacts Assessment underwent public consultations and were approved by the authorities.  RePACC received final approval by the Regional Council of Attica in December 2022.

Success and Limiting Factors

The factors that were decisive for a successful design of the adaptation strategy and plan mainly relied on the high commitment of the regional governance actors. The coordinator of the strategy and plan was the Environment Directorate of the Region of Attica. This regional authority has direct responsibility in preparing environmental policy guidelines at the regional level, focused on the conservation and protection of wetland ecosystems, also in view of climate change

The formulation of the wetland adaptation strategy and action plan followed a participative process. There was early engagement and strong collaboration with various stakeholders: central, regional and local services, other authorities, research agencies, environmental organisations and interested citizens. They were encouraged to take action through interviews, information meetings, workshops and training seminars. Experiences were exchanged; weaknesses and good/bad practices in the management and protection of Attica’s wetland biodiversity wealth were recorded; and the value of conserving wetlands and the need to adapt to climate change were promoted.

EU funding (coming from the transnational cooperation programme 2007 - 2013 South East Europe for the Orientgate project and from the EEA and Norway grants) were decisive in prompting the preparation of the adaptation strategy and action plan for the Attica region as well as for its gradual implementation in the following years.

The success of the Attica Wetland Action Plan was proven by the fact that it has been used as a baseline document for the new regional programming period of the Attica Region. As a result, specific measures have been integrated in the Attica RePACC and in the regional operational Program of Attica Region 2021-2027.

All regions in Greece have been called to prepare their RePACC, some of them include measures for the protection of wetlands. Therefore, the Attica experiences have a high potential to be replicated.

Another success factor is related to the evolution of the national legislation, with the law 4559 (August 2018), covering a total area of more than 460 ha. This law bans any building permits, drainage or other activities that might degrade the ecological status of wetlands.

There were no significant hindering factors during the elaboration of the adaptation strategy and plan. However, the implementation of the wetland adaptation action plan is expected to encounter several barriers. These relate to the availability of funds, operational capacity of involved services and bodies to undertake the proposed adaptation measures, regulation of land use in view of wetland protection and restoration. Measures that require institutional changes or regulatory legislation might be implemented with further delays.

Costs and Benefits

The implementation of the adaptation action plan is expected to mitigate the impacts of the combined effects of anthropogenic interventions and climate change on Attica wetlands. Improved protection of wetlands is also expected to improve their ecosystem functions, such as: (i) protection of the coasts by reducing the effect of waves and currents; (ii) improvement of water quality by trapping sediments, nutrients and toxic substances; (iii) support to economic activities depending on wetland resources. Other positive outcomes that derive from the implementation of the action plan include : the improvement of knowledge about climate change and its influence on wetland species, habitats and ecosystem functions; the enhancement of environmental awareness and development of information centres.

The development and implementation of the adaptation strategy and action plan for the Attica region also contributes to the inter-agency and regional coordination, inter-sectoral collaboration and institutional capacity to address climate change.

The development of the adaptation strategy and the action plan for Attica’s wetlands was co-funded by the OrientGate project and national funds with  a total of 150.000 Euros. This sum included travel and dissemination expenses.

The following project “Improving knowledge and increasing awareness for wetland restoration in the Attica Region” was co-funded with 85% coming from the EEA and Norway grants and with 15% from national funds (Greek Public Investment Programme), with a total budget of about 398.887 Euros.

Amongst others, a Road Map (2017) for the implementation of horizontal actions for Attica’s Wetlands as well as measures on 4 water bodies was elaborated within the framework of the above mentioned project. Those water bodies are Vourkari wetland (it has been characterized as Regional Park since 2017), Koumoundourou Lake, the mouth of Pikrodafni stream and the National Park of Scinias According to pre-estimates in this Road Map, the cost of the implementation for these actions/measures was almost 10 million €.

The Attica Wetland Action Plan integrated measures and priority actions which were foreseen by the existing legislation and fall under existing national strategic, policy and programming frameworks, including:

  • The National Operational Plan for the environment (2014-2020), which covers objectives and priority actions for: the water management sector and the implementation of the Water Management Plans; the conservation of nature and biodiversity through better management of the EU Natura 2000 network’s sites; the promotion of ecosystem services and green infrastructures for climate change adaptation based on natural solutions and for the management of flood risk.
  • The national strategy and action programme on biodiversity, which highlights the need for wetland conservation and adaptation to climate change and includes priorities such as delineation, restoration, research on climate change effects on biodiversity and ecosystems, and promotion of “high biodiversity islands” in urban environments as green infrastructures.
  • The national law on biodiversity and in particular the articles that cover the designation of wetlands as protected areas.
  • The Master Plan of Athens/Attica 2021, which lists Attica wetlands (including lakes, rivers, streams and their estuaries, springs, lagoons, and coastal marshes) and covers actions for their legal protection and their promotion as green infrastructures.
  • The River Basin Management Plan-Attica Water District (in the context of the Water Framework Directive implementation), which includes a specific measure for the restoration and promotion of Attica Wetlands.

Recently, two concrete measures of the Attica Wetland Action Plan have been integrated in the Regional Plan for Adaptation to Climate Change of Attica (RePACC, approved on 14 December 2022) and in the Operational Program of Attica Region 2021-2027 (policy target 2 “a greener low carbon transitioning towards zero net carbon economy”). The RePACC is to be revised every 5 years.

Municipalities of Attica Region are mobilized to take adaptation actions in the context of their local operational plans.

Implementation Time

The Strategy and Action Plan were formulated during the OrientGate project: 2012-2014. The first stage of the Attica Wetland Action Plan implementation took five years (2015-2020). The ongoing implementation stage of the Plan is taking place under the new policy framework of the Attica region, within the RePACC and the  Operational Program of Attica Region 2021-2027. The new  RePACC is considered as the next stage of the Action Plan. It integrated three measures directly linked to Attica Wetlands with implementation horizon up to 2018.

Life Time

The original strategy and action plan, formulated within the Orientgate Project, had a lifetime of about six years (2014-2020). The RePACC has a lifetime of 5 years (2022-2027), after that it is expected to be revised. The measures implemented to protect wetlands have an indefinite lifetime.
