Résumé :

The cultivation of Rhus coriaria has become necessary to preserve their wild populations. To be competitive in the international market, it is important to develop an efficient production chain to reduce costs and improve the quality of the products. The main objective of this study is to provide a method to determine the suitable areas to develop the R. coriaria cultivation with a case study in Gonabad County of Iran. A habitat suitability model (HSM) was applied to survey the distribution of R. coriaria and to identify the best areas the growing of its. Three different main criteria including environmental suitability, agronomic suitability, and social-economical suitability selected for the HSM. Then, each of the three main criteria and their multi-specific indicator was defined in Analytic Hierarchy Process (AHP) and the weights of them were calculated by pairwise comparison matrix. In the next stage, the weights are applied to their layers such as hypsometry, slope, slope aspect, mean annual precipitation, mean annual temperature, soil texture, landuse, water resource type, water resource quality and quantity, road network, and land ownership as roaster layers. The results of the HSM showed a weighted map of land suitability for the R. coriaria that included the maximum and minimum potential of areas for its planting. Based on these results, the areas with the highest suitability for the R. coriaria are strictly associated with precipitation, soil texture, and water resources type.

Résumé :

Hydroponics, a soil-less cultivation technique, offers efficient resource utilization and enhanced crop yields. However, precise water quality control is essential to ensure optimal nutrient absorption and successful crop growth. This research paper presents a comprehensive IoT-based water quality monitoring system specifically designed for hydroponics, incorporating pH, turbidity, and temperature sensors. The system can acquire data from sensors, data processing, and data visualization in real time. The sensor data is seamlessly transmitted from Arduino to ESP8266 and securely stored on the ThingSpeak cloud platform. Utilizing web scraping techniques, the collected data is extracted from ThingSpeak and seamlessly integrated into a user-friendly website. On the website, a machine learning (ML) model, trained on required data, automatically processes the realtime sensor readings and performs crop suitability predictions. The system enables continuous and automated monitoring of key water quality parameters, ensuring optimal conditions for hydroponic crop growth. The deployed ML model demonstrates remarkable performance in predicting water suitability for different crops. The model provides real-time predictions on the website by utilizing the data, empowering hydroponic farmers with data-driven insights to optimize crop selection based on water quality. To evaluate the system’s efficacy, extensive experimentation, and validation have been conducted using hydroponic setups with various crop types.

Résumé :

Cambodia suffers from devastating droughts in the dry season and floods in the wet season. These events’ impacts are further amplified by ineffective water resources infrastructure that cannot retain water during the dry season. Water harvesting (the collection and management of floodwater or rainwater runoff to increase water supply for domestic and agricultural use) is an approach that could improve Cambodia’s resiliency against droughts and floods. Despite the known benefits of water harvesting, there are currently few studies on water harvesting suitability in Cambodia. This research argues that suitable water harvesting sites can be identified by combining various expertise and evaluating hydrologic site conditions. Thirty-one local and USA water infrastructure experts made pairwise comparisons between essential engineering criteria: soil drainage, geologic porosity, precipitation, land cover, and slope. Then, model weights were calculated based on the comparisons. Using the model weights, a water harvesting suitability model showed that 19% of Cambodian land has high suitability, and about 13% of the land has the best suitability. This water harvesting model can help guide future water infrastructure projects to improve climate resiliency by identifying suitable sites for water harvesting reservoirs.

Résumé :

With the implementation of the Grain for Green Project, the apple plantation area is increasing in Loess Plateau. However, due to severe water scarcity, the sustainability of apple tree growth is threatened. In this paper, we used meteorological data (1990–2013) and forecasted climate data (2019–2050) to estimate water demand and establish a water suitability model to study the water balance between available water and water consumption of the apple trees. The results show that: (i) the order of the average water demand of apple plantation in each subarea is Shaanxi Province > Yuncheng area > Gansu Province > Sanmenxia Region, ranging from 500 to 950 mm; (ii) the temporal variability of water suitability from 1990 to 2013 is large, and the higher values are concentrated in the late growth stage of the apple trees and the lower values are concentrated in the early growth stage; (iii) the temporal and spatial distribution of water suitability is relatively stable and even in the Loess Plateau in the period of 2019–2050; (iv) the water suitability is mainly affected by effective precipitation and reference evapotranspiration and the reference evapotranspiration is mainly affected by the solar radiation (36%) and average temperature (38%). Furthermore, due to the joint influence of precipitation increases and solar radiation (average temperature) increases, the future water suitability of the apple plantation area in the Loess Plateau is showing a non-significant downward trend under RCP4.5 scenario.

Résumé :

The hydrological conditions a changing climate imposes require updated measures to address extreme water events sustainably. These must evolve from isolated solutions, such as water retention basins, to holistic management strategies that consider at least two situations simultaneously, such as floods and droughts. One strategy for sustainable groundwater management is managed aquifer recharge (MAR), which copes with decreasing groundwater levels by a targeted recharge of aquifers. Using high water as a recharge water source (Flood-MAR) can additionally cover the aspect of flood protection, resulting in a multi-beneficial solution for the region. This study evaluated the site suitability for subsurface floodwater storage schemes, which must focus more on assessing the existing aquifer characteristics and the specific flood dynamics in nearby rivers compared to known MAR schemes. Potential sites for underground flood storage are characterized by decreasing groundwater levels and, thus, frequent water scarcity, combined with eminent risks of flooding by a nearby river. Suitability, on the other hand, must take the aquifer, surface, and water source characteristics into account. In this study, we present a workflow for generating suitability maps for implementing subsurface floodwater storage systems with a geographic information system-based multi-criteria decision analysis (MCDA). The workflow was intentionally and exclusively based on publicly available data, was implemented in Python, and provided as open-source software. The resulting suitability maps spatially depict the feasibility of underground flood storage, and thus form the basis for the implementation planning of such projects. The approach was demonstrated for the administrative district of Swabia, Germany, where approximately 35% of the area was identified as suitable at varying levels. A sensitivity analysis of the assigned weights was applied to show the high robustness of the underlying data. The results highlighted the enormous potential of implementing such sustainable co-management schemes, which needs to be further concretized by on-site observations.

Résumé :

A study on site suitability analysis of small water impounding projects (SWIPs) in CALABARZON Region, Philippines was conducted using a GIS-based water resources assessment procedure for optimum water resourceallocation and utilization. The study involved primary data collection through needs and design assessment survey of farmer-respondents utilizing SWIPs, and geo-tagging of existing SWIPs in the CALABARZON region. Secondary data inputs were also gathered from various institutions to generate the thematic maps and the potential suitability maps for SWIPs. Location maps of existing and potential sites for the development of SWIPs in CALABARZON were generated though GIS-based mapping. The generated SWIP potential suitability map was classified as highly suitable, moderately suitable, or marginally suitable. There were eight (8) factors considered in site suitability mapping of SWIP, namely, (1) average annual total rainfall, (2) soil texture, (3) slope, (4) road accessibility, (5) potential irrigable area (PIA), (6) geology, (7) watershed area, and (8) reservoir area. Of the total 350 potential sites identified for SWIP development in the CALABARZON region, 7% were classified as highly suitable, 61% as moderately suitable, and 32% as marginally suitable. The results can serve as a tool for SWIP planning and development to augment irrigation requirements for sustainable food production in the region.

Résumé :

The Dniester is a transboundary river between Ukraine and the Republic of Moldova. It is the second longest river in Ukraine and the ninth in Europe. From its source to a town of Staryi Sambir, the Dniester flows through the Carpathian Mountains, then across the flat territory of Ukraine and Moldova. The Dniester Basin extends across seven regions in southwestern Ukraine (Lviv, Ivano-Frankivsk, Ternopil, Khmelnytskyi, Vinnytsia, Chernivtsi and Odesa Regions). A small area of the river in its upper reaches is located in Poland. The basin's shape is a very elongated oval that is curved in the middle, about 700 km long with an average width of 120 km. As it flows into the Black Sea, the Dniester River forms the Dniester estuary in Odesa region (between Ovidiopol and Bilhorod-Dnistrovskyi districts). The estuary area of the Dniester River is a complex landscape system at the sea-river-land contact. Drinking water is an important factor determining a person's health. Due to the intensive development of industry, agriculture and utility services, the number of pollutants that enter the environment and worsen the quality of drinking water in Ukraine keeps increasing. This increases the risk of toxic and infectious diseases spread among the population that consumes such low-quality water. That is why solving the problem of drinking water monitoring and assessment of its quality is a pressing task requiring urgent action. The article examines the quality of water for drinking needs at the water intake site of the Dniester River, a town of Biliaivka, for 2018-2022. Water quality assessment was carried out according to DSTU 4808: 2007 based on average and worst values. The methodology covers 80 indicators and, in accordance with sanitary legislation, is divided into seven separate groups (blocks). According to hygienic standards, the quality of river water is considered suitable for use if it belongs to quality classes 1-3. In this research, the analysis was carried out according to 23 indicators included in three groups, so the assessment is considered as tentative: Group I - organoleptic indicators (chromaticity, turbidity); Group II - general sanitary indicators (dry residue (mineralization), sulfates, chlorides, magnesium, alkalinity, hydrogen index, ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, phosphate phosphorus, dissolved oxygen, bichromate oxidation (COD), BSK5); Group VII – toxicological parameters (total iron, manganese, chromium (VI), zinc, petroleum products, synthetic surface active agents (surfactants), volatile phenols). It was determined that, according to the average values, the water quality of the Dniester at the water intake site is characterized as "good", which means it has clean water of acceptable quality. As for the worst indicators, the water was assessed as transitional in quality from "good" (clean) to "satisfactory" (slightly polluted).

Résumé :

We surveyed the opinions of 16 water quality experts in order to develop a water quality index for contact recreation in freshwaters in New Zealand. The index was developed by postal surveys using the Delphi method, involving feedback of information to the panel members at each iteration. Determinands selected for use in the index were as follows: faecal bacterial indicators (faecal coliforms or E. coli), pH, Munsell colour, visual clarity indicators (black disc visibility or turbidity), and nutrients promoting nuisance growths (filtered BOD5, and dissolved forms of phosphorus and nitrogen). “Sub-index” curves relating suitability-for-use to these water quality determinands have been developed. The mean (“consensus”) sub-index curves can be used to interpret water quality data in terms of suitability-for-use scores. We advocate using the lowest suitability-for-use score for a water as its overall index value for contact recreation. Thus the water body's suitability-for-use is determined by its “poorest”characteristic. The index is now ready to be tested by water managers for its utility in state-of-environment reporting.

Résumé :

Lampung bay is one of potential aquaculture for floating net cages. Site selection for cultivation is influential on the floating net cages cultivation production, while currently selected sites have not considered water quality suitability criteria. The study goals are to identify the optimal site for cage cultivation based on the water quality suitability and to examine the main affecting factor for the suitability of cage cultivation in Lampung Bay. The water quality suitability parameters including water depth, water clarity, current speed, sea surface temperature, salinity, pH, and dissolved oxygen. Field survey was conducted on the southern part of Lampung Bay which is close to the coastal urban area. The tools used consisted of GPS navigation, pH meter, secchi disk, refractometer, bathimeter, digital thermometer, current meter, DO meter, and sample bottles. There are 32 sampling points which are distributed systematically. Inverse Distance Weighted is used to obtain the spatial distribution of parameters. The water environment suitability is carried out using two models from the weighting result using GIS, i.e. binary model and weighted model. Based on these model, the optimal area for cage cultivation are 17.41% (200.97 ha) and 65.95% (761.29 ha) using binary and weighted model respectively. The most influential parameter in order to promote sustainable cage cultivation are the water depth parameter with the consideration of the pattern similarity with the final model. Physical waters suitability map produced from this study provides valuable information for farmers and decision makers in Lampung Province so the cages cultivation in Lampung Bay can continue and obtain the optimal results.

Résumé :

AbstractClimate change may drive shifts in global agriculture that will affect remaining natural lands, with important consequences for the conservation of species and ecosystems. Wine production is an excellent model for examining this type of impact, because suitable climate is central to product quality and production is centered in Mediterranean climate regions that are all global biodiversity hotspots. Adaptation to climate change in existing vineyards may involve water use to ameliorate heat stress or drought, resulting in additional conservation issues. Global studies of wine, climate, and conservation have highlighted the need for more detailed regional analyses to better understand these complex multiple issues. Here we examine impacts of climate change on winegrape suitability in California and its possible implications for nature conservation and water use. Under two global climate models and two emissions scenarios, winegrape suitability in California is projected to decline overall and to move into undeveloped areas that provide important habitats for native species. Coastal and upslope areas retain and improve in suitability, respectively, while inland areas see the largest losses in suitability. Areas of declining suitability are regions in which heightened water use for vineyard adaptation may lead to declines in stream flow or conflicts with other water uses. Continued growth in global demand for wine and reduced production in areas of declining suitability will drive expansion into newly suitable areas, potentially impacting important species native to California. Existing vineyards in areas of declining suitability will likely need to adapt to remain viable. Advance planning for a changing climate and adaptation options that are not water intensive (e.g. vine orientation, trellising, or varietal switch) will help reduce potential water conservation issues in those areas.

Résumé :

Extreme rainfall variability has been one of the major factors to famine and environmental degradation in Ethiopia. The potential for water harvesting in the Upper Blue Nile Basin was assessed using two GIS-based Multicriteria Evaluation methods: (1) a Boolean approach to locate suitable areas for in situ and ex situ systems and (2) a weighted overlay analysis to classify suitable areas into different water harvesting suitability levels. The sensitivity of the results was analyzed to the influence given to different constraining factors. A large part of the basin was suitable for water harvesting: the Boolean analysis showed that 36% of the basin was suitable for in situ and ex situ systems, while the weighted overlay analysis showed that 6–24% of the basin was highly suitable. Rainfall has the highest influence on suitability for water harvesting. Implementing water harvesting in nonagricultural land use types may further increase the benefit. Assessing water harvesting suitability at the larger catchment scale lays the foundation for modeling of water harvesting at mesoscale, which enables analysis of the potential and implications of upscaling of water harvesting practices for building resilience against climatic shocks. A complete water harvesting suitability study requires socioeconomic analysis and stakeholder consultation.

The average annual rainfall of 3000 mm in Kerala is 3 to 5 times more than many other states. But. in Kerala, rainwater is not much retained on the land due to the steep/undulating topography and low water holding capacity and shallow depth of topsoil. Most of the water stored in the soil during rainy season escape to the lower reaches and then to the rivers/sea. The subsurface dykes constructed at AMPRS, Odakkali using black polyethylene sheet and at Thrangalikadavu. across Bharatapuzha. using Sand-Cement-Bentonite grout was effective in increasing the sub-soil water reserve. The study revealed that water level during summer season at the dyke upstream rose by about 60 to 80cm. The wells constructed near the dyke. both for drinking water supply and lift irrigation yielded more water for longer duration

Résumé :

One of the most important dry agroecosystems in Colombia is found in the northern Guajira region, which has native inhabitants (sociocultural aspect) and semiarid zones (ecological aspect). This condition has resulted in great vulnerability in agricultural production systems to adverse climatic events, which require large scale action. For example, the establishment of agroclimatic suitability zones are needed to access information, for decision-making. The aim of this study was to carry out agroclimatic zoning in the municipality of Uribia (La Guajira) for agricultural production systems and animal feed species. The criteria used to identify the agroclimatic suitability zones included: plant coverage present in the municipality, soil suitability, water storage under water stress, regular conditions found in the municipality, and an extreme water deficit event. The evaluated conditions showed variations in agroclimatic suitability during the periods January to April and August to November. During an extreme water-deficit event between August and November, the suitable area for the establishment of production systems with plant species (type C3 and C4) was smaller (77,000 ha) than in the period January to April (130,000 ha). The agroclimatic suitability categories in Uribia did not exhibit differences between the evaluated periods under average water-deficit conditions.

Résumé :

The study aimed to determine groundwater’s suitability for irrigation and cattle rearing in Kuwait. In this regard, groundwater samples were collected from Umm Al Aish (UA) and adjoining Rawdhatain (RA) water wellfields to develop groundwater suitability maps for irrigation purposes using the fuzzy logic technique in ArcGIS. RA was dominated by Na-Cl, Na-Ca, and Ca-SO4 water types, whereas UA was dominated by the Ca-Mg water type. Due to the influence of the temperature and pCO2, the carbonates were inferred to be more susceptible to precipitation in the soil than the sulfates. The ternary plots for both regions revealed that the samples’ suitability ranged from good to unsuitable. Spatial maps of nine significant parameters governing the irrigation suitability of water were mapped and integrated using the fuzzy membership values for both regions. The final suitability map derived by overlaying all the considered parameters indicated that 8% of the RA region was categorized as excellent, while UA showed only 5%. Samples situated in the study areas showed an excellent to very satisfactory range for livestock consumption. Developing a monitoring system along with innovative water resource management systems is essential in maintaining the fertility of the soil and existing groundwater reserves.

Résumé :

The pressure on Egypt’s limited water resources has increased as a result of the country’s growing industrial and agricultural sectors, coupled with climate change impacts and population growth. To overcome the current water stress situation, the utilization of new technologies such as managed aquifer recharge (MAR) is thought to be key for expanding the use of non-conventional water resources and providing necessary water supplies. Managed aquifer recharge can boost groundwater recharge and promote greater water accessibility. Suitability maps for MAR are widely offered as a tool to aid in decision-making in the context of balancing water demand and supply. Conducting a sensitivity analysis to validate suitability mapping can enhance the understanding of the results and pinpoint the influencing factors. The West Delta region was chosen as a case study given the existence of two MAR sites to examine the suitability of implementing MAR projects with reclaimed water. In this work, a spatially explicit sensitivity analysis is performed on a newly developed framework for MAR suitability maps that use multi-criteria decision analysis (MCDA) to determine suitable locations for MAR implementation, using spreading methods techniques. The performed sensitivity analysis uses spatial visualization to examine the effect of various weighted criteria on the final outputs and identifies criteria that are especially sensitive to weight changes. The results of the sensitivity analysis indicate that the applied MCDA framework for the suitability mapping in West Delta produced robust results in terms of the most suitable sites for MAR. The obtained results also indicate the possibility of the use of the suggested framework for arid environments with comparable data availability. Moreover, the results emphasize the possible use of suitability maps in sustainable groundwater management plans to support the actual implementation of MAR projects in the West Delta.

Résumé :

The exacerbation of drought conditions has significantly enhanced water scarcity, notably impacting arid and semi-arid regions globally. Consequently, effective runoff management has emerged as a critical and formidable challenge. This comprehensive review addresses the critical challenge of runoff management for water resources sustainability, specifically through the lens of dam site selection employing MCA. A systematic investigation into the origins and methodologies of runoff management highlights the prevalent application of MCA models, with an in-depth literature review providing insights into various approaches, their advantages, limitations, and suitability for specific contexts. Through an extensive literature review, 63 criteria affecting dam site suitability were identified and analyzed, with slope, land use/land cover, and soil type identified as the most significant factors. The findings revealed an exponential increase in the application of MCA for dam site selection over the past two decades, emphasizing its growing importance in the field. Further, the review highlights the varied outcomes of dam site evaluations due to differing expert opinions on criteria weightings, pointing to the necessity for a unified approach to criteria weighting. It is recommended that future research focus on harmonizing these weights and incorporate high-resolution observational data to enhance the accuracy of dam site suitability assessments. Moreover, the integration of climate adaptability into runoff management models is suggested to ensure long-term water resource sustainability. This comprehensive review not only outlines the current state and challenges in runoff management and dam site selection but also proposes a direction for future research aimed at resolving these critical issues.

Résumé :

Assessing fish habitat suitability in a data-scarce tidal river is often challenging due to the absence of continuous water quantity and quality records. This study is comprised of an intensive field study on a 42 km reach which recorded bathymetry and physical water quality parameters (pH, electroconductivity, dissolved oxygen, and total dissolved solids) testing and corresponding water levels and velocity. Frequent water sampling was carried out on 17 out of 90 locations for laboratory water quality tests. Based on this, an interpolation technique, i.e., Inverse Distance Weighted (IDW), generates a map in a Geographic Information System (GIS) environment using ArcGIS software to determine the river water quality parameters. Additionally, a hydrodynamic model study was conducted to simulate hydraulic parameters using Delft3D software followed by a water quality distribution. During validation, the Delft3D-simulated water quality could reasonably mimic most field data, and GIS featured dissolved oxygen. The overall water quality distribution showed a lower dissolved oxygen level (~3 mg/l) in the industrial zone compared to the other two zones during the study period. On the other hand, these validated hydraulic properties were applied in the Physical Habitat Simulation Model (PHABSIM) set up to conduct the hydraulic habitat suitability for Labeo rohita (Rohu fish). Thus, the validated model could represent the details of habitat suitability in the studied river for future decision support systems, and this study envisaged applying it to other similar rivers.

Résumé :

Several programs have been undertaken during the last few years to install rooftop rainwater harvesting systems as an alternative drinking water supply source both in the coastal and arsenic affected areas in Bangladesh. In this study, quality of the harvested rainwater used for drinking water supply was assessed. A total of 308 harvested rainwater samples were collected from the different storage reservoirs located both in coastal and arsenic affected areas and analysed for various physical, chemical and microbial indicators. Most of the physical and chemical water quality parameters were well below the Bangladesh Drinking Water Standard and WHO guideline values. However, the harvested rainwater was found microbiologically contaminated to some extent and the water is not suitable for consumption without treatment. For safe and sustainable rainwater harvesting, WHO guideline and water safely plan (WSP) can be adopted in Bangladesh.

Résumé :

Groundwater is a vital source of irrigation and domestic purposes in Bangladesh, and hence, it must satisfy the water quality guidelines. The study has selected eleven (11) Districts of Bangladesh and collect secondary data regarding the irrigation water quality of groundwater. Several irrigation water indices, such as soluble sodium percentage (SSP), sodium adsorption ratio (SAR), magnesium adsorption ratio (MAR), residual sodium carbonate (RSC), Kelly’s ratio (KR), permeability index (PI), and irrigation water quality (IWQ) index are applied to evaluate irrigation water quality. According to IWQindex, the results showed 25.5% of water samples fell in highly suitability water type, whereas 33.5% exhibited low suitability type, and the remaining 41% were showed medium suitability for irrigation purposes. The values of SAR, SSP, RSBC, and MAR indices showed that about 31-64% of water samples were very good, whereas 5-20% were very poor for the same purpose. The results of TDS, EC, and total hardness showed good results as 88-93% of water samples fell in fair to excellent quality. The salinity hazard was found in the groundwater of coastal areas and completely unfit for irrigation. The study findings would help for improving the management of the groundwater resources for agricultural purposes in Bangladesh.
