“…The Yamuna and many other rivers are getting polluted and contaminated on receiving the considerable quantity of untreated wastewater drained from urban and industrial sources [2]. Total wastewater generation from urban areas in India is above 39,000 MLD, out of which only 34% is treated [3]. Major Indian cities also extract effluent from sewage treatment plants (STP) for agriculture and industrial usage, therefore, quality of STP effluents stands critical from human, animal and crops health as well as an ecological point of view.…”

“…Farmer's especially poor and marginal one, lift STP effluent during the summer season due to the scarcity of river water. The efficiency of STP and the quality standards of its effluent show a significant impact on the quality of Yamuna water and irrigate crops which can be detrimental to crop quality, soil, human and animal health and environmental quality [3].…”

The study aims to investigate the current extent of physicochemical parameters and heavy metal contamination in the effluent of the Jaganpur sewage treatment plant (STP), Dayalbagh, Agra India. Majority of the nearby farmers have access to use of STP effluent in irrigation purposes for growing major edible crops. The problems of using STP effluent for irrigation purpose, continuous water quality analysis required. To check the quality of irrigation water, substantial physicochemical parameters accordance to Indian Standards (IS-Reaffirmed 2002/2003) analysed to calculate Sodium absorption ratio (SAR) and Residual sodium carbonate (RSC). To estimate the heavy metal pollution index (HPI) and metal quality index (MQI), toxic Heavy metals such as As, Cr, Mn, Fe, Ni, Cu, Zn, Pd, Cd, Co, and B also determined in the STP effluent with an AAS and results verified with ICP-OES against certified standards. The high value of SAR (range 13 to 20) and RSC (range −10 to 11) in STP effluent exceeded the permissible limit for irrigation purpose. On the other hand, HPI and MQI values (1692.4 and 58.1, respectively) show that high metal contamination mainly due to industrial and domestic wastewater does not treat appropriately in the sewage treatment plant. Thus it is suggested that further studies are carried out on the STP effluents to improve the water quality through proper treatment. Treated wastewater used for irrigation purposes needs to analyse the contamination like heavy metals and pinpoint the pollution sources.

“…Crop yields and blue water use under irrigated treatments were greater than those of the rainfed system. This is because rainfed cropping has a zero on-farm blue water footprint with no water extracted for irrigation [44]. Similar ranges for the majority of life cycle environmental impacts (the change is less than 10%) were found for both conventional and smart irrigation.…”

Olive cultivation is expanding rapidly in the northwestern part of Greece, under both rainfed and irrigated practices. Irrigation can result in larger yields and economic returns, but trade-offs in the water–energy–pollution nexus remain a controversial and challenging issue. This study presents an environmental Life Cycle Assessment (LCA) of Greek olive orchard systems in the plain of Arta (Epirus), comparing rainfed (baseline), Decision Support System (DSS)-based (smart) irrigation practices and farmer experience-based (conventional) irrigation practices. The contributions in this paper are, first, to provide a first quantitative indication of the environmental performance of Greek olive growing systems under different management strategies, and second, to detail the advantages that can be achieved using smart irrigation in olive cultivation in the Greek and Mediterranean contexts. Eighteen midpoints (e.g., climate change, water scarcity, acidification, freshwater eutrophication, etc.), two endpoints (damages on human health and ecosystem quality), and a single score (overall environmental impact) were quantified using the IMPACT World+ life cycle impact assessment method. The LCA model was set up using the OpenLCA software v1.10.3. The functional units were 1 ton of product (mass-based) and 1 ha of cultivated area (area-based) on a cradle-to-farm gate perspective. Irrigated systems had the lowest impacts per mass unit due to higher yields, but showed the highest impacts per cultivated area. The DSS-based irrigation management could reduce water and energy use by 42.1% compared to conventional practices. This is translated into a reduction of 5.3% per 1 ton and 10.4% per 1 ha of the total environmental impact. A sensitivity analysis of impact assessment models demonstrated that the benefits could be up to 18% for 1 ton of product or 22.6% for 1 ha of cultivated land. These results outline that DSS-based irrigation is a promising option to support less resource-intensive and sustainable intensification of irrigated agriculture systems in the plain of Arta.

“…As one can see in Table 3, consumers pointed out that "grains and grains products", "fruits and juices" and "vegetables, nuts and beans" were the main 3 products where effort and attention should be paid according to consumers, especially in grains and vegetables. Of course, the use of irrigation in agricultural systems, leads to higher yields and also produces a high impact on water sustainability [33]. However, protein-rich products (e.g., lamb, cheese, pig meat, and peas and nuts), olive oil, and milk are the food items needing the highest volumes of freshwater [6].…”

How Consumers Perceive Water Sustainability (HydroSOStainable) in Food Products and How to Identify It by a Logo

Water is the most essential resource for food production and socioeconomic development worldwide. Currently, industry and agriculture are the most water consuming activities, creating high levels of pollution, and intensifying the scarcity of water especially in arid regions. The term “hydroSOStainable products” has been used to define those foodstuffs grown under irrigation strategies that involve optimized water management. A study to understand how consumers perceive options to save water in the food chain and how to identify the water sustainable products by a logo, was conducted in Brazil, China, India, Mexico, Spain and USA, with 600 consumers per country. In all countries, consumers think that the food categories in which it is possible to save the most water are those linked directly to agricultural products: (i) “grains and grain products” and (ii) “vegetables, nuts and beans”. Also, consumers do not associate processed products, such as snacks, with high water consumption, even though they come from agricultural products such as grains and require more processing. The logo was positively rated by consumers, especially by young generations. There is a need to properly inform consumers about water sustainability to gain their confidence in the hydroSOS logo.
