Application of multicriteria analysis in the Management and Planning of Treated Municipal Wastewater and Sludge reuse in Agriculture and Land Development: The case of Sparti’s Wastewater Treatment Plant, Greece. Fresenious Environmental Bulletin, 20 (2), 287-295.
Abstract
Reclaimed wastewater and biosludge reuse is a multifactor problem directly related to environmental planning and management. The rational and effective disposal in the agroecological environment depends on the balanced interaction of spatial, technological, environmental, social-political and economical parameters. Consequently, an optimum solution could be achieved by the application of a Multicriteria Decision Analysis (MCDA), which could take into account all the above parameters. This type of model taking into consideration the local constraints, is currently considered as offering the most compatible solution for such complex problems of conflicting and opposing interests.
A MCDA was applied to the management of the Sparti’s Wastewater Treatment Plant (WWTP) output with the view to find an optimum solution of the wastewater and biosludge disposal. Three scenarios were formulated based on the above parameters. It was found that the best (optimum or compatible) scenario was the 2nd one, according to which the outputs of the Sparti’s WWTP could be applied successfully to an agricultural area of Laconia’s prefecture cultivated with horticultural citrus and olive trees.

Abstract The degradation of groundwater quality, which has been noted in the recent years, is closely connected to the intensification of agriculture, the unreasonable use of chemical fertilizers and the excess consumption of large volumes of irrigation water. In the hilly region of central Thessaly in Greece, which suffers the consequences of intense agricultural use, a hydrogeological study is carried out, taking groundwater samples from springs and boreholes in the Neogene aquifers. The aim of this study is the investigation of irrigation management, water quality and suitability for various uses (water supply, irrigation), the degradation degree and the spatial distribution of pollutants using GIS. The following hydrochemical types prevail in the groundwater of the study area: Ca–Mg–HCO3, Mg–Ca–Na–HCO3 and Na–HCO3. In the above shallow aquifers, especially high values of NO3- (31.7–299.0), NH4 +(0.12–1.11), NO2- (0.018–0.109), PO4 3- (0.07–0.55), SO42- (47.5–146.5) and Cl- (24.8–146.5) are found, particularly near inhabited areas (values are in mg L-1). The water of shallow aquifers is considered unsuitable for human use due to their high polluting load, while the water of the deeper aquifers is suitable for human consumption.
Regarding water suitability for irrigation, the evaluation of SAR (0.153–7.397) and EC (481–1,680 lS cm-1) resulted in classification category ‘C3S1’, indicating high salinity and low sodium water which can be used for irrigation in most soils and crops with little to medium danger of development of exchangeable sodium and salinity. The statistical data analysis, the factor analysis and the GIS application have brought out the vulnerable-problematic zones in chemical compounds of nitrogen and phosphates. The groundwater quality degradation is localized and related exclusively to human activities. Based on 2005 and 2008 estimates, the annual safe yield of the region’s aquifers were nearly 41.95 MCM. However, the existing situation is that 6.37 MCM of water is over extracted from these aquifers.

Abstract
Drip irrigation may constitute a method for sustainable management of water resources and can contribute to environmental protection and sustainability. However, there is still limited information on the application of drip irrigation to row field crops in Mediterranean environments, especially with respect to its appropriate lateral layout, a parameter that affects initial system installation cost as well as water use efficiency. Surface drip irrigation (SDI) field experiments with sugar beets (Beta vulgaris L.) were conducted in central Greece over a 3-year period to determine the effects of different layout designs (4 treatments with 6 replications) on root yield, sucrose accumulation characteristics (percent sugar content of roots (POL), raw sugar yield), water productivity index (WPI), and to study the contribution of different layout designs to environmental protection and sustainability. The treatments used consist of combinations of drip-pipes with varying lateral distances of every-other-furrow (e-o-f) (1.00 m) and every-threefurrows (e-t-f) (1.50 m), and between the dripper spacing (0.50 m and 0.75 m). The mean root yield results in the e-o-f treatments were 108.46, 111.46 and 105.11 t·ha-1, and in the e-t-f treatments were 106.17, 113.59 and 103.84 t·ha-1 for each year, respectively. The root sugar contents varied from 11.68% to 13.00% in e-o-f and from 11.46% to 13.41% in e-t-f. The WPI results were 19.74, 19.44 and 17.97 kg·m-3 in e-of, and 19.32, 19.81 and 17.75 kg·m-3 in e-t-f, respectively. Differences in root yield, POL, raw sugar yield and WPI between the 3 harvest periods were not statistically significant (corresponds to an initial cost reduction of -37.2%. Moreover, using this method, important installation labour savings, as well as cost reductions for transportation and storage facilities, are realized.
Keywords: Sugar beet yield, drip irrigation layouts, time domain reflectometry (TDR), water productivity index (WPI), aquic soil moisture regime, plastic material reduction.

Abstract
The scope of present work was the modelling and mapping of maize biomass yield in correlation with water quality and irrigation water management effects in an experimental field with combinational use of in situ measurements and Information and Communication Technologies (ICT) such as Geographic Information Systems (GIS), Global Positioning System (GPS), Geostatistical modeling. The investigation of drip irrigation frequency effects in yield and in the proportion of biomass in the various plant parts and in the distribution of soil moisture were studied, in an experimental parcel of three interventions (i.e. irrigation per 9, 12 and 15 days) in a four replications, randomized complete block design (RCBD) with systematic plot arrangement, in a farm located in central Greece (Larissa), at the farming period of year 2003. The cut plants fractions results for the distribution of above ground biomass (dry matter), were: 47.74 % grain, 26.72% stalk, 11.43% leaf, 7.25% cob, 6.86% husk, and for the distribution of biomass in stover (dry matter) were: 49.75% stalk, 22.27% leaf, 16.22% cob and 11.76% husk. The mean biomass in stover yield was found 11,562.99 kg ha-1. It was observed that the 9 days irrigation treatment resulted in the greatest biomass in stover yield (13,198.02 kg ha-1) and the highest potential for Bioethanol production (5,411.18 L ha-1), and from the statistical analysis of the plots harvested mean biomass yields, it was found that their values were significantly different at level of significance p < 0.05. ICT provided significant insight into the nature of biomass yield and the field’s spatial variability as effected of the integrated irrigation water management and its biofuel potential, aiming at water savings and environmental protection.

Abstract
In the E.U. following the old 5th Environmental Action Program (EAP) of 1994 and the new 6th EAP for the sustainable development in 2001, we confront the strategic management problem of aquatic resources at the regional and watershed level. What should be the goals for a new strategic management of natural and aquatic resources in a Region of Greece such as Thessaly? The present paper is concerned with the protection, prevention and strategic environmental planning of aquatic resources and water purification in the Thessaly basin as well as the protection of these resources from the pollution and depletion, which might result from various national water resource programs and plans which are already in operation. The aforementioned aim is a product of research on the goals, actions and proposals, which depict the problem of aquatic resource management related to pollution, the link with agricultural activities and the overall problem of water. Primarily, a general profile of the water situation and problems is presented for the Thessaly basin, including water pollution and the problems related to the rational management and protection of aquatic resources. Also, the prevention of natural water-involved disasters is explored which in turn points to the need for a new strategic scheme for environmental management of aquatic resources and purification and to the institution of new water policy actions and measures for the Thessaly basin in central Greece.
