“…These changes are attributed predominantly to human activities in conjunction with poor management practices, which have caused numerous negative consequences such as development of deficient water balance and reduction of groundwater resources, water resource quality degradation [2], groundwater head decline, saline water intrusion along coastal areas and surface and ground water quality deterioration [3,4].…”

Abstract:The Gallikos River basin is located in the northern part of Greece, and the coastal section is part of a deltaic system. The basin has been influenced by anthropogenic activities during the last decades, leading to continuous water resource degradation. The holistic approach of the Driver-Pressure-State-Impact-Response (DPSIR) framework was applied in order to investigate the main causes and origins of pressures and to optimize the measures for sustainable management of water resources. The major driving forces that affect the Gallikos River basin are urbanization, intensive agriculture, industry and the regional development strategy. The main pressures on water resources are the overexploitation of aquifers, water quality degradation, and decrease of river discharge. Recommended responses were based on the Water Framework Directive (WFD) 2000/60/EC, and sum up to rationalization of water resources, land use management and appropriate utilization of waste, especially so effluent. The application of the DPSIR analysis in this paper links the socioeconomic drivers to the water resource pressures, the responses based on the WFD and the national legislation and is as a useful tool for land-use planning and decision making in the area of water protection.

“…Water supply in Greece is largely derived from groundwater sources, and about 9 % of the approximately 1.4 Mha of irrigated land is affected by soil salinisation due to seawater intrusion (Jones et al, 2003;OECD, 2009). Seawater intrusion in most coastal areas of Greece has progressed a great distance inland, especially in the south, which is characterised by a more arid climate (Daskalaki and Voudouris, 2008). The island of Crete ( Fig.…”

Evaluation of promising technologies for soil salinity amelioration in Timpaki (Crete): a participatory approach

et al. 2016

Abstract. Soil salinity management can be complex, expensive, and time demanding, especially in arid and semi-arid regions. Besides taking no action, possible management strategies include amelioration and adaptation measures. Here we apply the World Overview of Conservation Approaches and Technologies (WOCAT) framework for the systematic analysis and evaluation and selection of soil salinisation amelioration technologies in close collaboration with stakeholders. The participatory approach is applied in the RECARE (Preventing and Remediating degradation of soils in Europe through Land Care) project case study of Timpaki, a semiarid region in south-central Crete (Greece) where the main land use is horticulture in greenhouses irrigated by groundwater. Excessive groundwater abstractions have resulted in a drop of the groundwater level in the coastal part of the aquifer, thus leading to seawater intrusion and in turn to soil salinisation. The documented technologies are evaluated for their impacts on ecosystem services, cost, and input requirements using a participatory approach and field evaluations. Results show that technologies which promote maintaining existing crop types while enhancing productivity and decreasing soil salinity are preferred by the stakeholders. The evaluation concludes that rainwater harvesting is the optimal solution for direct soil salinity mitigation, as it addresses a wider range of ecosystem and human well-being benefits. Nevertheless, this merit is offset by poor financial motivation making agronomic measures more attractive to users.

“…The types of aquifers that dominate are karst aquifers and coarse grained Neogene and Quaternary deposits (porous aquifers). The dominant hydrochemical type of groundwater in Greece is the one of Ca-Mg-HCO 3 representing freshwater of recent infiltration (Daskalaki and Voudouris, 2007).…”

“…Nitrate pollution due to agricultural activities (pesticides, fertilizers, etc), as well as due to existing cesspools used for untreated domestic effluent, has become a pressing and important problem nowadays. Sea intrusion is a second groundwater quality problem in Greece, mainly faced by overexploited coastal aquifers (Daskalaki and Voudouris, 2007).…”
