The basic aim of this paper is to present the existing conditions and problems of water resources management in Greece. Water demand has increased tremendously over the past 30 years. Despite adequate precipitation, water imbalance is often experienced, due to temporal and regional variations of the precipitation, the increased water demand during the summer months and the difficulty of transporting water due to the mountainous terrain. Integration of reclaimed wastewater originating from the wastewater treatment plant effluents into the water resources management is proposed. This plan exhibits the potential for reducing the pollution loads entering sea or inland waters, while at the same time providing water for irrigation.

Sustainable Water Resources

Understanding the response of Himalayan-Karakoram (HK) rivers to climate change is crucial for ~1 billion people who partly depend on these water resources. Policymakers tasked with the sustainable water resources management for agriculture, hydropower, drinking, sanitation, and hazards require an assessment of rivers’ current status and potential future changes. This review demonstrates that glacier and snow melt are important components of HK rivers, with greater hydrological importance for the Indus than Ganges and Brahmaputra basins. Total river runoff, glacier melt, and seasonality of flow are projected to increase until the 2050s, with some exceptions and large uncertainties. Critical knowledge gaps severely affect modeled contributions of different runoff components, future runoff volumes and seasonality. Therefore, comprehensive field- and remote sensing-based methods and models are needed.

Judging from the current status of water resources all over the world, the analysis of our country the need for reuse of rainwater and its practical significance at this stage. The using of rain water from domestic and foreign , and the actual situation of the construction of rainwater collection, processing, using of systems, rain water reuse in the case of water quality standards implementation rainwater recycling of resources. The water resources are shortage is another important practical problem ,the rainwater reuse is our country's new way to solve water resources pool. However, the disposing process of rain still has some practical problems, which will be necessary to further our study and resolve.

Multi Method Approach

<p>Coastal lagoons are unique and complex ecosystems. Resulting from both terrestrial (fresh groundwater and surface water) and marine water influences, these ecosystems are often maintained by direct or indirect groundwater supplies and collectively known as groundwater dependent ecosystems (GDEs). Because they provide a wide range of ecosystem goods and services on which a large part of the human population depends, coastal GDEs are considered as complex socio-economic and ecological component worldwide. The increasing human development in coastal areas induces yet a strong pressure on water resources and the expected effects of climate change could exacerbate the pressures on these environments. To limit the risks of degradation and to ensure the sustainability of ecosystem services, the implementation of proper water resources management strategies is essential. This requires a strong knowledge of the environmental and socio-economic trajectories of hydrosystems, and particularly of the behavior and role of groundwater.</p><p>To this end, only the combined use of several tools allows a global understanding of the spatial and temporal dynamics of the system. The correlation between isotopic tracers (<sup>18</sup>O, <sup>2</sup>H, <sup>3</sup>H, <sup>15</sup>N, <sup>11</sup>B), anthropogenic contaminants (organic micro pollutants) and mapping approaches (land-use and vulnerability) allows a historical analyze of the hydrosystem. In addition, to better constraint the hydrosystem hydrological behavior, it is also possible to highlight the current status of water resources, the historical legacy of pollutants and the consequences of past developments and practices, which continue to jeopardize the current quality of the water resource. This methodology was applied to a Mediterranean hydrosystem, in connection with a coastal lagoon (Corsica Island, France). The identification of degradation processes and their chronology could then be traced back in time.</p><p>It appears that the current deterioration is mainly due to a legacy pollution resulting from the development of policies implemented 60 years earlier. In the case of coastal GDEs that are highly anthropized and subject to ever-increasing development, this methodology proposes new key elements for the establishment of relevant management strategies to ensure the future sustainability of water resources.</p>

<p>En este artículo se describe la situación actual de disponibilidad y demanda de recursos hídricos de Costa Rica, así como la evolución del marco legal e institucional para la planificación y la gestión.  Costa Rica tiene 51 100 km<sup>2</sup> de superficie y contiene 34 cuencas nacionales. La vertiente del Caribe representa el 46,4% del país, mientras que la vertiente del Pacífico corresponde a 53,6%. Costa Rica también tiene el 34,3% del territorio en dos cuencas transfronterizas, Rio San Juan con Nicaragua y el Río Sixaola en Panamá.</p> <p>En el territorio hay 12 embalses hidroeléctricos que suman un total de 95 km<sup>2</sup> de superficie y 217 cuerpos de agua naturales que cubren 40,5 km<sup>2</sup> de superficie. El balance hídrico anual promedio a nivel nacional para el período 1970-2002 es la siguiente:</p> <p>3297 mm de precipitación, 2.215 mm de escorrentía y 996 mm de evapotranspiración. Se estima que el suministro potencial agua de Costa Rica es equivalente a 113 km3 de escorrentía que corresponde para el 2005 a una disponibilidad de agua per cápita de 26 221 m<sup>3</sup>/persona/año. El volumen utilizable aguas subterráneas a nivel nacional se estima en 11 km3 de agua, lo que resulta en un flujo sostenible de 350 m<sup>3</sup> / s.</p> <p>Se estima que en 2005, las extracciones de agua para diversos usos ascendieron a unos 22 km<sup>3</sup> o el 20% del volumen de agua disponible. La extracción de agua para la generación de energía hydroeléctrica representó el 72% del total, seguido de la agricultura con un 21,2%. El uso para el consumo humano, el turismo, la industria y la agroindustria representó el 6,8% del total y un 88% de este volumen proviene de fuentes subterráneas, lo que destaca la importancia estratégica de la protección y la explotación sostenible de los acuíferos del país. Las proyecciones del uso del agua para el año 2020 para todos los usos alcanzan a 37,87 km<sup>3</sup>, equivalentes a más del 33% de la disponibilidad total de los recursos hídricos del país.</p> <p>Los dos problemas principales son la ausencia de una única institución con plena responsabilidad en la planificación y la gestión de los recursos hídricos y que la ley actual del agua es obsoleta. Por lo Tanto, es urgente adoptar una nueva ley sobre el agua con una visión moderna para conducir la reorganización del sector, redefinir un nuevo esquema de tarifas de agua para financiar la investigación, el desarrollo, la planificación y la conservación del recurso. Sin esta herramienta legal, los recursos hídricos del país seguirán siendo sobreexplotados, creando desequilibrios y conflictos entre sectores sociales y productivos, el aumento de vulnerabilidad a la contaminación y los riesgos para la salud pública.</p>
