“…The article by García-Caparrós et al (2018) describes a study on the possibilities of using a blending of drainage with water of low electrical conductivity and the sequential reuse and sequential irrigation in a sequential productionhorticultural and ornamental plants under greenhouse conditions. This irrigation technique would reduce the water footprint of crop under greenhouse conditions.…”

Bibliometric analysis of water footprint research in countries of former Yugoslavia

Sustainable development of water resources requires new tools and research in these fields of study. A systematic overview of water footprint research in countries of former Yugoslavia is presented through bibliometric analysis and publication review. The Scopus database was used as the data source. Among the countries of former Yugoslavia, only researchers from Slovenia, Serbia, Croatia, and Bosnia and Hercegovina published papers focused on water footprint research before March 2021. Research on water footprint in these countries was found to be insufficient in scope and intensity. The contribution of authors from the countries of former Yugoslavia is small compared to research in other countries all over the world but is not insignificant. Almost 2/3 of articles have already been cited by other authors. Two main centers of water footprint research are at the University of Maribor in Slovenia and at the University of Novi Sad in Serbia, respectively. The research is focused on the so-called volumetric water footprint, while the LCA water footprint stands outside the interest of the scientific community in countries of former Yugoslavia.

“…A final model that relates the relative crop yield (Y a /Y M ) and the salinity of the nutrient solution CE w was obtained by combining Equations (5) and (6). The proposed model is given in Equation (7) and depicted in Figure 7:…”

“…The development of efficient and sustainable methods to manage salinity in intensive semiarid irrigation systems is an active field of research. Among these methods, the use of closed soilless cropping systems with recirculation of leachates or cascade cropping systems [7] have been proposed by several researchers as an efficient way to improve the water use efficiency (WUE) in intensive semiarid irrigation systems affected by severe salinization [8]. Other scientists have proposed intercropping halophytic species, able to accumulate salts in their tissues, to mitigate salinity stress in a watermelon crop [9].…”

The aim of this work was to analyze the influence of the salinity of the nutrient solution on the transpiration and growth of Cordyline fruticosa var. “Red Edge” plants. A specific irrigation management model was calibrated with the experimental data. An experiment was performed with four treatments. These treatments consisted of the application of four nutrient solutions with different electrical conductivity (ECw) levels ranging from 1.5 dS m−1 (control treatment) to 4.5 dS m−1. The results showed that day-time transpiration decreases when salt concentration in the nutrient solution increases. The transpiration of the plant in the control treatment was modelled by applying a combination method while the effect of the salinity of the nutrient solution was modelled by deriving a saline stress coefficient from the experimental data. The results showed that significant reductions in plant transpiration were observed for increasing values of ECw. The crop development and yield were also affected by the increasing salinity of the nutrient solution. A relationship between the ECw and the relative crop yield was derived.

“…This setup helps to reduce water and nutrient losses by closing resource flows (Ahmed et al, 2000;Agung Putra and Yuliando, 2015). However, it demands additional infrastructure, which requires high investment costs (De Pascale and Maggio, 2005;García-Caparrós et al, 2018) and increases the environmental impacts of the system (Rufí-Salís et al, 2020). Moreover, the high salinity of the drained water can cause yield reduction if it is directly recirculated to the crop without treatment or partial discharge (Magán et al, 2008;Grewal et al, 2011).…”

“…The authors found that the species used presented a good bioremediation potential based on the uptake of nitrogen (N) and phosphorus (P). García-Caparrós et al (2018) also explored this potential using horticultural melon as the donor crop and ornamental rosemary as the receiving crop, finding a decrease in yield in the receiving crop, but also a great potential to optimize the water flows and remove the nitrates of the drained water. To our knowledge, there are no references in the literature exploring the potential of horticultural species (both as donor and receiving crops) to produce vegetables while mitigating nutrient depletion through the use of a cascade system and the quantification of the nutrient flows.…”

Closed-Loop Crop Cascade to Optimize Nutrient Flows and Grow Low-Impact Vegetables in Cities

Urban agriculture systems can significantly contribute towards mitigating the impacts of inefficient and complex food supply chains and increase urban food sovereignty. Moreover, improving these urban agriculture systems in terms of nutrient management can lead to a better environmental performance. Based on a rooftop greenhouse in the Barcelona region, we propose a cascade system where the leachates of a tomato cycle from January to July (donor crop) are used as the main irrigation source for five successive lettuce cycles (receiving crop). By determining the agronomic performance and the nutrient metabolism of the system, we aimed to define the potential of these systems to avoid nutrient depletion and mitigate eutrophication, while scaling the system in terms of nutrient supply between the donor and the receiving crops. The results showed that low yields (below 130 g per lettuce plant) are obtained if a cascade system is used during the early stage of the donor crop, as the amount of nutrients in donor’s leachates, specially N (62.4 mg irrigated per plant in the first cycle), was not enough to feed the lettuce receiving crop. This effect was also observed in the nutrient content of the lettuce, which increased with every test until equaling the control (4.4% of N content) as the leachates got richer, although too high electrical conductivity values (near 3 dS/m) were reached at the end of the donor crop cycle. Findings on the uptake of the residual nutrient flows showed how the cascade system was able to take advantage of the nutrients to produce local lettuce while mitigating the effect of N and P in the freshwater and marine environments. Considering our case study, we finally quantified the scale between the donor and receiving crops and proposed three major ideas to optimize the nutrient flows while maintaining the yield and quality of the vegetables produced in the receiving crop.
