Wastewater Use In Agriculture Research Articles

Sustainable management of wastewater use in agriculture: a systematic analysis

Due to changes that have occurred in ecological conditions, the requirement to use wastewater has been considered more seriously in the agricultural sector, because agriculture is the source of human nutrition, health and security. Based on this, the purpose of this research was to systematically analysis the components affecting sustainable management of wastewater use (SMWWU) in the viewpoint of critical theory paradigm. Inductive qualitative content analysis (IQCA) was used for systematic analysis. In this regard, the software used was MAXQDA. The statistical population included valid scientific articles and knowledgeable experts in wastewater management in the agricultural sector in Tehran province, Iran. The sampling method for articles was by searching based on keywords and for experts by purposeful method until theoretical saturation was reached. The results of IQCA in the form of a model showed that the six main components “economic,” “environmental,” “contextual,” “individual,” “management and planning” and “education and extension” affect SMWWU. Each of these components also includes several factors and variables that can strengthen SMWWU and reduce the water crisis by paying attention to them. The obtained model can be used by policy makers and interested parties in making decisions and planning water protection measures.

Exploring Factors Shaping Farmer Behavior in Wastewater Utilization for Agricultural Practices: A Rapid Review

In recent years, circular economy strategies have gained attention in agriculture, particularly regarding the utilization of wastewater as an alternative water source. This study employs a rapid review methodology to examine farmers’ attitudes toward wastewater use in agriculture. By analyzing studies in literature published from 2000 to 2023, this review identifies the key factors influencing farmers’ adoption of wastewater irrigation. These findings are valuable for policymakers seeking to develop targeted policies that support and encourage the adoption of wastewater irrigation, thereby contributing to sustainable water resource management.

Application of Sanitation Safety Planning in the Usage of Wastewater for Agriculture in Bangalore Urban District, India.

Due to water scarcity, wastewater is used in agriculture in peri-urban areas. We aimed to assess the hazards associated with wastewater farming and develop an incremental improvement plan for the sanitation system of wastewater use for agriculture using Sanitation Safety Planning (SSP) in Bangalore urban district, India. Interviews and observations were conducted among 100 farmers in the Mugalur Gram Panchayat area. Direct ingestion and ingestion after contact with wastewater due to inadequate hand hygiene are the routes of contact with wastewater. The control measures followed in the community are the cultivation of crops, which do not have direct contact with wastewater, furrow and drip irrigation, and restricted irrigation. Methods to mitigate the hazards are the provision of interval between final irrigation and consumption,washing of produce with freshwater before transportation to market, and hygienic cooking. Occupational hazards and risks associated with wastewater farming can be mitigated through the adoption of locally acceptable preventive measures.

Critical attributes and considerations for selecting irrigation systems for wastewater

With increasing global population, the gap between the supply and demand for water is widening and poses a threat to human existence. In the face of water scarcity, urban wastewater is increasing in its attention as an alternate water source for crop production. However, several challenges such as toxicity hazards, salinity build-up and health concerns have been identified with the use of wastewater in agriculture. There are several technological solutions that can help ameliorate or lower the level of contamination associated with using wastewater for irrigation. This paper explores the use of some irrigation technologies to abate the toxicity and health concerns associated with wastewater irrigation. The paper identifies some decision parameters for the selection of identified irrigation technologies and subjects them to multi-criteria decision analysis (MCDA) to rank them based on the level of exposure of the crop and irrigator/field worker to contamination among other relevant criteria. This paper validates that limiting the contact of the wastewater with the edible parts of the crop, especially for leafy vegetables, can minimize contamination to the crop and field workers. Though not totally without constraints, the identified irrigation methods present prospects for a cleaner and more sustainable production with regard to wastewater usage in agriculture. Sub-surface drip irrigation systems were identified as the best irrigation system for filtered and treated wastewater followed by surface drip and pitcher irrigation. Irrigators can fall back on some of these identified methods for wastewater application for sustainable crop production and maximized food safety.

Effect of freshwater and wastewater irrigation on buildup of toxic elements in soil and maize crop.

Untreated wastewater is routinely used for agricultural activities in water-stressed regions, thereby causing severe ecological risks by various pollutants. Hence, management strategies are needed to cope with the environmental issues related to wastewater use in agriculture. This pot study evaluates the effect of mixing either freshwater (FW) or groundwater (GW) with sewage water (SW) on the buildup of potentially toxic elements (PTEs) in soil and maize crop. Results revealed that SW of Vehari contains high levels of Cd (0.08mg L-1) and Cr (2.3mg L-1). Mixing of FW and GW with SW increased soil contents of As (22%) and decreased Cd (1%), Cu (1%), Fe (3%), Mn (9%), Ni (9%), Pb (10%), and Zn (4%) than SW "alone" treatment. Risk indices showed high-degree of soil-contamination and very-high ecological risks. Maize accumulated considerable concentrations of PTEs in roots and shoot with bioconcentration factor > 1 for Cd, Cu, and Pb and transfer factor > 1 for As, Fe, Mn, and Ni. Overall, mixed treatments increased plant contents of As (118%), Cu (7%), Mn (8%), Ni (55%), and Zn (1%), while decreased those of Cd (7%), Fe (5%), and Pb (1%) compared to SW "alone" treatments. Risk indices predicted possible carcinogenic risks to cow (CR 0.003 > 0.0001) and sheep (CR 0.0121 > 0.0001) due to consumption of maize fodder containing PTEs. Hence, to minimize possible environmental/health hazards, mixing of FW and GW with SW can be an effective strategy. However, the recommendation greatly depends on the composition of mixing waters.

Characterization of producers who use wastewater for irrigation of vegetables and forages

Objective: To characterize the production systems of the users of Chilhuacán canal waters located in Atlixco, Puebla and to identify the role they play in the persistence of wastewater use in agriculture. Design/Methodology/Approach: A characterization of regional producers was conducted applying a questionnaire and making field visits to the producers’ plots. Results: There are seven types of producers who specialize in different types of crops (forages and vegetables); they also use agricultural areas of different sizes (< 3ha, ≤ 6ha and > 6 ha). Limitations/Implications: Wastewater use in agriculture is a recurring phenomenon in the world (including Mexico). As a result of the low water availability, wastewater is used to irrigate crops for human consumption. Findings/Conclusions: The awareness of the producers about the impact of this practice is low and they have no interest in the harmful polluting effects on their plots and their health.

LAS GRANJAS PORCINAS EN ZONAS DE KARST: ¿CÓMO PASAMOS DE LA CONTAMINACIÓN A LA SUSTENTABILIDAD?

<p><strong>Introduction</strong>: The state of Yucatán is the third national producer of pork meat due to a large number of pig farms, there are them of all sizes from very small to mega-farms with more than 30 000 pigs, many of which generate environmental and social problems. <strong>Objectives</strong>: The analysis of the operation of pig farms in Yucatán; identification of environmental problems; and proposals for mitigating damage to the environment and human health. <strong>Results</strong>: The environmental problem is generated by the large amount of water with which they operate to clean the farms and cool the pigs during high-temperature days. In addition to the large volumes of water extraction, large volumes of wastewater are generated that are not properly treated and that contaminate air, soil, and groundwater. In this work, the traditional way of operating farms is documented, emphasizing environmental damage. The particularities of karst landscapes and their environmental vulnerability are explained. <strong>Implications</strong>: Ways of reducing environmental problems are proposed with the idea that they are taken into account to move towards sustainable management of pig farms in the state of Yucatán, for example, selection of the best sites for pig farming (relief, soils, climate, and depth of groundwater), reduction of extracted water, treatment through artificial wetlands and agricultural use of wastewater through sprinklers in soils of the Luvisol, Nitisol and Vertisol groups. <strong>Conclusions</strong>: For the transit of contamination to Sustainability in the management of pig farms in the state of Yucatán requires knowledge, innovations to solve problems, social commitment with local communities, and environmental regulations. It will not be easy but it is possible.</p>

The WHO Guidelines for Safe Wastewater Use in Agriculture: A Review of Implementation Challenges and Possible Solutions in the Global South

Globally, the use of untreated, often diluted, or partly treated wastewater in agriculture covers about 30 million ha, far exceeding the area under the planned use of well-treated (reclaimed) wastewater which has been estimated in this paper at around 1.0 million ha. This gap has likely increased over the last decade despite significant investments in treatment capacities, due to the even larger increases in population, water consumption, and wastewater generation. To minimize the human health risks from unsafe wastewater irrigation, the WHO’s related 2006 guidelines suggest a broader concept than the previous (1989) edition by emphasizing, especially for low-income countries, the importance of risk-reducing practices from ‘farm to fork’. This shift from relying on technical solutions to facilitating and monitoring human behaviour change is, however, challenging. Another challenge concerns local capacities for quantitative risk assessment and the determination of a risk reduction target. Being aware of these challenges, the WHO has invested in a sanitation safety planning manual which has helped to operationalize the rather academic 2006 guidelines, but without addressing key questions, e.g., on how to trigger, support, and sustain the expected behaviour change, as training alone is unlikely to increase the adoption of health-related practices. This review summarizes the perceived challenges and suggests several considerations for further editions or national adaptations of the WHO guidelines.

Using Wastewater for Agriculture in Faisalabad: Appraisal of Socio-Cultural and Economic Outcomes

The urban slums deprived of basic human needs like drinking water, and sanitation facilities are spreading in major cities like Faisalabad, Karachi, and Lahore. The wastewater generated in houses and foul water of rain is being thrown away directly into open channels or in covered sewers. The wastewater collected at disposal stations either after treatment or as such is being used for agriculture purposes by farmers placed in surrounding villages. The reuse of wastewater for agriculture is influencing the physical ecosystem as well as cultural and socio-economic situations of the community. The study was carried out to appraise cultural and socio-economic outcomes of using wastewater for agriculture in Department of Sociology, Government College University Faisalabad during January-March 2020. The data were collected both from primary and secondary sources. Certain transact walks in area of the study were made and consultative meetings with key informants were also held. 60 farmers who were using wastewater for agriculture, were selected by simple random sampling techniques. The appraisal of data revealed that reuse of wastewater for agriculture activities had positive impacts on cultural and socio-economic aspects of the rural community. The results indicated that reuse of wastewater for agriculture activities had many positive impacts on cultural and socio-economic aspects of the rural population. Price of agricultural land, rent of land, and households’ monthly income were increased. Employment opportunities were also generated. The perception of community about most of the environmental improvement was better. However, perception of farmers about impact on public health, soil structure and groundwater resources were medium or low. It is also concluded that use of wastewater for agriculture is a beneficial source of plant nutrients and organic matter required for retaining the richness and output levels of soil that enhance living standards of inhabitants and lessen poverty.

Soil and crop spatial variability in maize irrigated with domestic effluent

Wastewater use in agriculture is a high-potential alternative for coping with water scarcity. The present study aimed to evaluate the impact of using wastewater and sewage sludge on soil attributes in an irrigated maize plantation in the Brazilian northeastern semi-arid region, at an experimental reuse unit. Two experimental plots were installed with the following treatments: wastewater and sludge, and irrigation with wastewater only. The presence of sludge reduced the salt content and promoted an increase in the soil organic matter content, reducing the salinization risk. Biometric parameters showed no spatial dependence. On the other hand, soil moisture, electrical conductivity, sand content, clay content and sodium and potassium contents showed strong spatial dependence for the treatment with sludge application.

Groundwater deterioration in Akhmim District, Upper Egypt: A Remote Sensing and GIS investigation approach

Groundwater has a special significance in Akhmim area as it is used mainly in various purposes. However, groundwater is currently threatened by pollution from different sources. Therefore, detailed field investigations, in addition to Geographic Information Systems and remote sensing techniques are integrated to study the main sources of deterioration in groundwater quality and proposing practical solutions for mitigation and remediation. Based on the Modified Normalized Difference Water Index (MNDWI) and physicochemical analysis of groundwater samples, areas that contribute to groundwater deterioration have been identified. The results showed that the main causes of groundwater deterioration are the use of sewage rooms and injection wells to get rid of sewage especially in rural areas and scattered settlements, discharging liquid industrial wastes into the ground without proper treatment, the random exploitation of groundwater, and the use of wastewater in agriculture in a random manner. The results of the physicochemical analysis of groundwater samples confirmed the sources of deterioration identified by satellite images and field studies. To avoid groundwater degradation, strict restrictions need to be applied on the use of untreated or treated wastewater for irrigation, sewage networks have to be established in all residential areas, and factories must treat wastewater before discharging it.

Influence of Cropping Practices on the Persistence and Vertical Migration of Escherichia coli from Wastewater in Hydromorph Soil in Wet Tropical Zone

Little attention is paid to the influence of cultivation practices on the persistence and vertical migration of undesirable bacteria in hydromorphic soils as they have increased the risk of crop recontamination. Therefore the objective of this study was to determine the implication of some cultural practices on the persistence and vertical migration of E. coli in the soil. In this study, raw sewage (single application) and stream water (multiple application) were applied on lettuce, carrot and aubergine plots. The results revealed that overall, E. coli persisted longer on plots with crops and were more persisted in the rainy season on all cultivated plots that had received wastewater from the sewage treatment plant until harvest. While in the dry season, it was only detected at harvest on lettuce plots. The E. coli rate increased gradually overtime on the plots that had received water from the watercourse. Aubergine was the only plant that significantly facilitates the vertical migration of E. coli to the water table. On the whole, crops favored the persistence of E. coli on the soil surface and therefore increase the health risk related to the use of wastewater in agriculture.

Sendo assim o objetivo do presente trabalho foi avaliar a absorção de macronutrientes e sódio pela cultura do tomate irrigado com e sem déficit hídrico, utilizando água residuária. O experimento foi conduzido em ambiente protegido, o sistema de irrigação foi por gotejamento, e o manejo da irrigação foi baseado na evaporação do tanque classe ‘A’ instalado dentro do ambiente. Foram determinadas duas lâminas: 70 e 100% da evapotranspiração da cultura, nas quais foram utilizadas água de abastecimento e de esgoto doméstico tratado em quatro diluições: 25, 50, 75 e 100%. Assim, foi possível avaliar a absorção de macronutrientes e sódio, na área foliar e frutos, através de análise química. Os resultados obtidos, indicaram que as plantas irrigadas com déficit hídrico absorveram maior quantidade dos nutrientes N, K, Mg e S. No entanto quanto maior a porcentagem de água residuária na irrigação, maior foi a absorção de sódio pelas plantas e frutos.

ABSORPTION OF MACRONUTRIENTS AND SODIUM BY TOMATOES SUBMITTED TO NORMAL AND WATER DEFICIENT IRRIGATION SCHEMES USING VARIOUS CONCENTRATIONS OF WASTEWATER 2 ABSTRACT The high worldwide demand for water use in economic development and domestic consumption has led to studies on the agricultural use of wastewater that can help minimize the problem of scarcity of this resource. This study aimed to evaluate the absorption of macronutrients and sodium from cultivated tomatoes, irrigated with wastewater, under normal and water deficient irrigation schemes. The experiment was conducted in a greenhouse, we used a drip irrigation system that was managed on the basis of evaporation from a Class A tank placed in the experimental area. Two irrigation depths were determined: 70 and 100% of the crop evapotranspiration, supply water, and four dilutions of domestic wastewater were used: 25, 50, 75, and 100%. We evaluated the absorption of macronutrients and sodium via chemical analysis of the leaves and fruits. Results showed that plants irrigated using the water deficit irrigation scheme absorbed more N, K, Mg, and S nutrients. However, the higher the percentage of wastewater used for irrigation, the higher the absorption of sodium by plants and fruits. Keywords: nutrition, domestic reuse, irrigation management, Lycopersicon esculentum L.

Barriers in Implementation of Wastewater Reuse: Identifying the Way Forward in Closing the Loop

The business case for circular economy in water management perspective has gain relevance in the recent times. By 2030, it is estimated that 160% of global total available water will be required to satisfy demand of anthropogenic-related activities and increasing waste-related water will be produced. Gaps on the conceptual framing of water reuse within supply chain management are clearly emerging and the demand for decision support systems helping at assessing effective water consumption in industrial setting is pressing. Despite the numerous local initiatives towards wastewater resource usage, barriers remain for its implementation in practice. Through a systematic review of previous studies in this field, the barriers towards the uptake of wastewater use in agriculture were classified according to the PESTEL (political, economic, social, technological, environmental and legal) framework. Alongside political and legal support, it is identified that for an economically and environmentally sustainable scheme for incentivising the deployment of feasible technologies, there is also a need to gain acceptance for wastewater usage in society in order to enhance the deployment of existing technological solutions. Addressing these factors in tandem can aid the development towards a circular economy for wastewater.

Tertiary Treatment of Livestock Wastewater in the Context of Alternative Water Resources for Sustainable Agriculture

The limited availability and quality of water resources are key issues of water management, and the protection and preservation of water resources are a requirement in the context of accelerated economic growth and principles of sustainable development. The experimental research presented in this paper is based on the need to identify alternative water sources and support unconventional wastewater treatment methods which would enable their reuse in areas affected by water scarcity and drought. Livestock wastewater contain significant levels of nutrients (nitrogen and phosphorus) and may represent an attractive water source for crop irrigation. This paper evaluates the efficacy of a proposed technological process for tertiary wastewater treatment consisting of two steps: electrochemical treatment for the removal of suspended and colloidal impurities and ozone disinfection. The experimental results showed higher efficiencies for the removal of chemical pollutants (92.5% COD, 79.3% BOD, 98.6% TSS, 41% residue saline) and significant inactivation of microorganisms (over 99.9% for total coliform bacteria and in some cases 100% for faecal coliform bacteria and faecal streptococci). The quality of the effluent complies with the regulations for wastewater use in agriculture and allows its reuse for different categories of use considering the required conditions for soil/crops. The successful application of treated wastewater to agricultural crops depends in a high extent on the good practices aimed on the improvement of crop yield and quality, optimisation of soil productivity and protection of the environment undertaken by the economic entities.

Sustainable Use of Wastewater in Agriculture: A Bibliometric Analysis of Worldwide Research

It is estimated that at least one quarter of the world’s population will be affected by water shortages in the coming years and by 2030 there will be a global water deficit of 40% if urgent action is not taken. Currently, the main consumer of water globally is agriculture. In addition, it has been estimated that to meet the demand for food by 2050, the water available for agricultural irrigation would have to increase by 70%. In this context, wastewater could become a relevant water resource to meet this growing demand. This article aims to show the state of the global research on sustainable use of wastewater in agriculture. To this end, a systematic qualitative analysis and a quantitative bibliometric analysis were conducted. The search was carried out for the period 2000–2019, and the analyzed sample comprised 1986 articles. The results show that this line of research is one of the most outstanding within agriculture and has gained special relevance during the last five years. Research has improved significantly at a technical level, but problems such as energy consumption, and the elimination of heavy metals and elements of chemical and pharmacological products, still need to be refined. There is a particular lack of contributions covering social aspects. This article can serve as a reference for both researchers and stakeholders interested in this topic.

Technology for preparation of contaminated water from poultry farms for irrigation

Studies of the possibility of using wastewater from poultry enterprises for irrigation of light chestnut soils using sprinkler machines have shown that wastewater needs preliminary treatment. Currently, it remains relevant to search for the most effective and cost-efficient ways to treat wastewater. We propose wastewater treatment by sedimentation on natural zeolite, after which the treated effluents can be discharged into storage ponds for further use in agriculture using sprinklers. For sewage treatment, the settling method was used, before which the particle size distribution of zeolite tuffs was selected and the size of fractions was selected using sieves. The sedimentation was carried out at regular intervals on a natural sorbent (zeolite tuffs). As a result of the study, the optimal contact time of the natural sorbent with the studied effluents was selected, which allowed to reduce the concentration of impurities present to the value below the maximum permissible one. As a result of settling for 80 minutes, there is a decrease in the concentration of chemical impurities in the studied poultry runoff to the maximum permissible concentration. Irrigation with wastewater diluted in 1: 4 with pure water increased the yield of spring wheat compared to the control option by a factor of 1.5. The absorption of organic substances by a soil layer 0.6 m thick is 80-100%. Agricultural use of wastewater diluted 6-7 times provides additional net income from the cultivation of spring wheat by 40%.

A critical analysis of wastewater use in agriculture and associated health risks in Pakistan.

Freshwater shortage and its contamination with various types of pollutants are becoming the most alarming issues worldwide due to impacts on socioeconomic values. Considering an increasing freshwater scarcity, it is imperative for the growers, particularly in semiarid and arid areas, to use wastewater for crop production. Wastewaters generally contain numerous essential inorganic and organic nutrients which are considered necessary for plant metabolism. Besides, this practice provokes various hygienic, ecological and health concerns due to the occurrence of toxic substances such as heavy metals. Pakistan nowadays faces a severe freshwater scarcity. Consequently, untreated wastewater is used routinely in the agriculture sector. In this review, we have highlighted the negative and positive affectivity of wastewater on the chemical characteristics of the soil. This review critically delineates toxic metal accumulation in soil and their possible soil-plant-human transfer. We have also estimated and deliberated possible health hazards linked with the utilization of untreated city waste effluents for the cultivation of food/vegetable crops. Moreover, we carried out a multivariate analysis of data (144 studies of wastewater crop irrigation in Pakistan) to trace out common trends in published data. We have also compared the limit values of toxic metals in irrigation water, soil and plants. Furthermore, some viable solutions and future viewpoints are anticipated taking into account the on-ground situation in Pakistan-such as planning and sanitary matters, remedial/management technologies, awareness among local habitants (especially farmers) and the role of the government, NGOs and pertinent stakeholders. The data are supported by 13 tables and 7 figures.

Analysis of Barriers and Opportunities for Reclaimed Wastewater Use for Agriculture in Europe

This paper presents an analysis of the perception regarding reclaimed wastewater reuse in agriculture conducted in the European Union regions. The analysis is based upon a SWOT framework and applies a cluster analysis to reduce the dimension of the responses enabling an assessment of the different perceptions of water reuse. More than one hundred key actors identified among the regions participated in the evaluation of the relevance of aspects identified. The results indicate some groups of countries according to natural conditions (water scarcity) and the strategic role of agriculture as a key factor to determine agent’s perceptions and attitudes. The results indicate that the forthcoming EU regulation of water reuse should focus in the problems of the perceived high cost of reclaimed water for farmers and the sanitary risk perception for irrigated crops by consumers as the critical points for fostering the use of reclaimed water in agriculture and the need for regional implementation of the global regulatory framework.
