Εκτίμηση της οικολογικής παροχής: η περίπτωση ποταμών στο Εθνικό Πάρκο Δέλτα Αξιού - Λουδία - Αλιάκμονα
No full textΓια την εκτίμηση της οικολογικής παροχής στο Εθνικό Πάρκο Δέλτα Αξιού-Λουδία-Αλιάκμονα εφαρμόστηκε η μέθοδος της Ενδοποτάμιας Αυξητικής Ροής, η οποία: Περιλαμβάνει την εφαρμογή υδραυλικών ομοιωμάτων, τα οποία υπολογίζουν τη μεταβολή της έκτασης του ενδιαιτήματος ειδών-στόχων σε συνάρτηση με
τη μεταβολή της παροχής του ποταμού (υδραυλικό μέρος). Αξιολογεί την επίδραση των μεταβολών της παροχής στα γνωρίσματα και
τη διαθεσιμότητα του ενδιαιτήματος ειδών του ποταμού (δομή κοίτης, υδατικές παράμετροι κ.ά.). Η μέθοδος της Ενδοποτάμιας Αυξητικής Ροής εφαρμόστηκε με επιτυχία στο εκβολικό τμήμα μήκους περίπου 11 km σε δύο μεγάλους ποταμούς της Κεντρικής Μακεδονίας, στον Αξιό και στον Αλιάκμονα
Mapping and assessment of the state of wetland ecosystems: a Mediterranean perspective
Get PDFAuthors: Marco Trombetti, Dania Abdul Malak, Antonio Sanchez (ETC-UMA); Anis Guelmami (Mediterranean Wetlands Observatory, Tour du Valat); Nieves Garcia (environmental consultant); Eleni Fitoka (Greek Biotope / Wetland Centre - EKBY)The Pan-Mediterranean wetland ecosystem map fills a major knowledge gap in the region by setting a Mediterranean-wide knowledge base on wetland ecosystems following the Ramsar definition of wetlands. The wetland ecosystem mapping is complemented by the assessment of wetland biodiversity conditions that aims
to highlight priority areas for potential conservation and restoration actions in
the region, and to support the regional efforts in advocating for effective wetland
management and nature-based solutions in the Mediterranean region. The outputs of this activity include (i) a Pan-Mediterranean wetland ecosystem knowledge base, and (ii) an assessment of their condition that will be used to raise awareness and advocate for a change in wetland management that promotes effective protection, conservation and restoration. The outputs also support regional and national inventories, filling a major regional gap locating Mediterranean wetland habitats, and feed regional and global agendas, namely the EU Biodiversity Strategy to 2030, the Mediterranean Strategy for Sustainable development as well as
the Ramsar Convention
Εθνικό Πάρκο Λιμνών Κορώνειας-Βόλβης και Μακεδονικών Τεμπών - Εκπαιδευτικό υλικό
Get PDFΤο εκπαιδευτικό υλικό αναδεικνύει, μέσα από σύγχρονες παιδαγωγικές μεθόδους και προσεγγίσεις, τη σημασία της προστατευόμενης περιοχής. Αποτελείται από σύντομο κείμενο παρουσίασης του Εθνικού Πάρκου, από παιδαγωγικές δραστηριότητες συνοδευόμενες από σχετικές οδηγίες για την υλοποίησή τους, καθώς και από ένα φύλλο αξιολόγησης του υλικού.
Τα αντικείμενα μελέτης αρθρώνονται με τρόπο ώστε να συνθέτουν συνολικά τις διαφορετικές όψεις και διαστάσεις του Πάρκου (π.χ.
γεωγραφία, βλάστηση, χλωρίδα, πανίδα, πολιτισμός, ανθρώπινες δραστηριότητες). Τα παιδιά εργάζονται, ατομικά ή ομαδικά, σύμφωνα
με συγκεκριμένες γραπτές οδηγίες που περιέχονται στις δραστηριότητες και σύμφωνα με τις υποδείξεις και οδηγίες του εκπαιδευτή. Καθώς το υλικό απευθύνεται σε παιδιά ηλικίας 6-12 ετών (μεγάλο εύρος σε επίπεδο γνωστικό, ικανοτήτων και δεξιοτήτων), επιχειρήθηκε το εκπαιδευτικό υλικό να περιλαμβάνει
δραστηριότητες που να καλύπτουν τις απαιτήσεις των παιδιών τόσο της μικρότερης, όσο και της μεγαλύτερης ηλικίας
Assessing lake vulnerability to climate change using the coupled MIKE SHE/MIKE 11 model: Case study of Lake Zazari in Greece. Paper presented at 11th World Congress on Water Resources and Environment (EWRA 2019) “Managing Water Resources for a Sustainable Future”. Madrid, Spain, 25-29 June 2019
No full textIf the worst predictions of general circulation models (GCMs) about climate change become true, then lakes will hardly manage to maintain their current conditions (Zhang et al. 2016) especially in regions, which have been identified as climate change hot spots such as the countries of Mediterranean Basin (Loizidou et al. 2016) from which Greece is of special interest since it has 54 lakes/reservoirs of 0.5 km2 minimum size.
The hydrological models are important tools for assessing the water balance components of lakes and for supporting the design of water management strategies. Depending on the modelling purposes and the specific attributes of a lake, different types of models and different levels of model complexities can be selected, starting from complex models such as MIKE SHE (Abbott et al. 1986), WATLAC (Zhang 2011) or using simpler methods (Yang et al. 2018). The MIKE model is among the most integrated models and has been used in the past for similar cases (Singh et al. 2010), while in combination with the future climate projections of general circulation models (GCMs), can be used to investigate lake conditions under future climate scenarios. The aim of this study is to present an application for analyzing the vulnerability of a lake to climate change using the MIKE SHE/11 model using as a case study the Lake Zazari in Greece
Enhanced wetland monitoring, assessment and indicators to support European and global environmental policy
Get PDFSWOS Technical publicationBetween 2015 and 2018, the Horizon 2020 SWOS
project has supported policies by developing
and applying science-based methods that aim at standardising wetland definition, identification, delimitation, and delineation. The primary outputs of the project are satellite-based monitoring tools
(SWOS toolbox1, GEO-Wetlands Community
Portal2) to enable improved wetland assessment and monitoring capabilities, as well as their application in management and reporting at different scales, and by different users. In addition, the SWOS project includes a capacity-building
component to facilitate the uptake of the tools by users. This report presents the project’s technical results (Chapter 3), as well as applied examples of the improved capabilities for wetland conservation and restoration needs (Chapter 4). These two chapters are preceded by an introduction (Chapter 1) and a review of the global
and EU policies related to wetlands, including a perspective on the post-2020 agenda (Chapter 2)
Setting the Phosphorus Boundaries for Greek Natural Shallow and Deep Lakes for Water Framework Directive Compliance
Get PDFKagalou I, C. Ntislidou, D. Latinopoulos, D. Kemitzoglou, V. Tsiaoussi, and DC Bobori. 2021. Setting the Phosphorus Boundaries for Greek Natural Shallow and Deep Lakes for Water Framework Directive Compliance. Water 13(5):739. https://doi.org/10.3390/w13050739Eutrophication caused by nutrient enrichment is a predominant stressor leading to lake
degradation and, thus, the set-up of boundaries that support good ecological status, the Water Framework Directive’s main target, is a necessity. Greece is one of the Member States that have recorded delays in complying with the coherent management goals of European legislation. A wide range of different statistical approaches has been proposed in the Best Practice Guide for determining appropriate nutrient thresholds. To determine the nutrient thresholds supporting the good status of natural Greek lakes, the phytoplankton dataset gathered from the national monitoring programme
(2015–2020) was used for shallow and deep natural lakes. The regression analyses were sufficient and robust in order to derive total phosphorus thresholds that ranged from 20 to 41 μg/L in shallow and 15–32 μg/L in deep natural lake types. Nutrient boundaries that encompass the stressors these lakes are subject to, are essential in proper lake management design
