Accepting the positive results that public participation can bring in the implementation of the Water Framework Directive (WFD), this paper seeks to contribute to ongoing discussions on the rather problematic WFD implementation in southern Europe. Within this framework, we fi rst focus on the national level and the analysis of 'water governance' and 'public participation' within the context of WFD implementation in Greece, and secondly on the examination of the participatory methods introduced locally for the preparation of the Evrotas River Basin management plan. The fi rst section focuses on public participation as an indispensable ingredient of good water governance. The next focuses on the introduction of the WFD as an instance of governance that promotes participatory arrangements. We then present the centralized structure of the Greek state as an impediment to the introduction of public participation in water governance. The fourth section focuses on the Evrotas River Basin and describes the participatory arrangements for the preparation of the management plan. The paper concludes with the verifi cation of the need for participatory processes to respect the context within which they are pursued and with specifi c alterations to the way public participation has been planned and implemented in Greece.
The hydrologic and geochemical conditions that prevail in Mediterranean temporary ponds (MTPs), create a unique environment for many rare and endangered species. Mediterranean temporary ponds are habitats of high ecological value, which are vulnerable to imminent climatic changes, as well as to human activities. This article examines the hydrology and the nitrogen and phosphorous geochemical cycles of four MTPs in Crete. Field and laboratory studies provided the necessary information for the development of a conceptual understanding of the hydrologic and biogeochemical processes that affect the fate of nitrogen and phosphorous in these MTPs. Their hydrology was driven by deposition, infiltration, and evaporation. The hydroperiod of the ponds varied between 40 and 160 d. Mineralization and nutrient release capacity experiments illustrated the significant role that MTP sediments played in enhancing the geochemistry of the aqueous phase. Such ecosystem functions (i.e., mineralization, nutrient release) exhibited high variability among MTPs necessitating site-specific studies with immediate implications to management. It is very important to understand the local hydrogeochemical and climatic conditions to ensure appropriate environmental measures for their management and conservation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
