Abstract:
Hydroponics farms have become a new trend in the Agricultural sector, especially with the growing needs of food and also because of the limited resources. The purpose of the research project was to gain knowledge about the modern Farming Method. The findings of the research suggest that in about 5-10 years of time the hydroponic business is eyed to increase about 200%-300%compared to the present situation. The food products produced by Hydroponics method are both nutritious and organic. The limited use of resources in hydroponic farming makes this method the tool for future sustainability. The complete analysis of the research has been made by using 2 basic research tools .One is an online survey, conducted to collect the information regarding people views about Hydroponics. The other tool was an interview with a local Hydroponic Grower.

Abstract:
Lettuce (Lactuca sativa L.) is the most commonly consumed leaf vegetable in the Brazilian diet, and it is a good source of vitamins and minerals. It is widely grown in the conventional farming system. However, the hydroponic farming system has been gaining importance in the market, wining confidence from consumers, who are becoming increasingly more demanding on food quality. The objective of this study was to evaluate the performance of two lettuce cultivars on hydroponic and conventional farming systems for the production of fresh mass (FM) and dry mass (DM), photosynthesis, contents of chlorophyll and anthocyanin. The following two experiments were carried out: hydroponics farming (HF) and conventional farming (CF), performed in protect and unprotect environments, respectively, in Florianópolis, SC. Mimosa Verde cultivar (MV) showed greater fresh mass than Mimosa Roxa (MR), in both farming systems and the two cultivars presented better performance in the hydroponic system (287.7 g MV and 139.1 g MR) than the conventional system (129.7 g MV and 111.8 g MR). Mimosa Verde cultivar presented lower average contents of total chlorophyll (7.7 mg g-¹ FM) than Mimosa Roxa (11.8 mg g-¹FM), and both cultivars displayed higher means for this variable in the hydroponic farming system. Mimosa Roxa presented higher contents of anthocyanin in the conventional system (88.24 mg g-¹ FM) than the ones in the hydroponic system (36.89 mg g-¹ FM). The best results for CO2 net assimilation rate regarded to photosyntheticaly active photon flux density were found in the hydroponic system, for both lettuce cultivars. Variation in the contents of chlorophyll were also found. Those variations were higher in the protected system than in the hydroponic system and contents of anthocyanin were higher in the conventional system.

Abstract:
The more rapid growth of technology allows humans to work effectively and efficiently. Technology proves the way humans change patterns of significant social change, from those that initially used human power to machines. The way humans use machines is inseparable from the ways and techniques of its use which are effective and efficient. One of the technologies used is the technology of crop cultivation without using soil as a planting medium. The technology introduced is hydroponics. Hydroponics as a way of farming is an approach that has several advantages, namely the use of agricultural land that is not extensive, and the system is not too complicated. The introduction of this technology aims to provide insight and knowledge to the public about the technology of crop cultivation in addition to conventional farming systems. This activity was carried out in Rayung gumuk Village, Glagah District, Lamongan Regency. The hydroponic system that we introduce is the NFT hydroponic system (Nutrient Film Technique). The goal is because the hydroponic system is easily applied and has several significant advantages. The first method of implementation is socialization.This is done to find out the extent to which people's insights and knowledge about hydroponics and the interests and interests of the community towards hydroponic using the NFT system. Moreover, the second is training. It aims to provide techniques and methods for assembling NFT hydroponic installations. From the results of our activities, the community's response to hydroponics is still minimal because some of them still consider hydroponic use too costly and their disinterest in agriculture.

Abstract:
The aims of the study were to analyze the increase in household income of hydroponics doers, to analyze how much increase in income obtained by hydroponic doers through the transfer of hydroponic farming technology in Bali Province and whether hydroponic agriculture can be made into sustainable agriculture.The study was conducted in Bali Province. Study time March-June 2017. Data collection method in this research was through survey and interview. The variables observed in this study were household income from hydroponic farming. The survey and interview data were analyzed by quantitative method by calculating all initial investment, income per harvest, the amount of other costs during one harvest. The quantitative data, then qualitatively explained to give explanation and the meaning of the numbers obtained from the quantitative calculation. The results of the analysis indicate that farming hydroponic systems can increase or be able to provide additional income to households. Therefore, through hydroponic farming, sustainable agriculture efforts will be realized. The increased income can be calculated by comparison of initial investment of Rp.5,000,000.00, compared to income derived from the sale of the vegetables. The income consists of: 1) kale vegetable, per one harvest (3 months) of 10 kg Rp.50,000.00= Rp.500,000.00. In one year, 3 times harvest= Rp.1,500,000.00. 2) Lettuce income three times harvest in one year 10 kg x Rp.75,000.00= Rp.750,000.00.(3 times harvest/year). Then, the total income/year of the hydroponic plant is Rp.2,250,000.00. Costs incurred for 1 year for both vegetable plants is Rp.400,000.00. Income difference and expense of Rp.1,850,000.00 - depreciation Rp.715,000.00 (7 years benefit period)= net income Rp.1,135,000.00. If the investment period is 7 years, the net value for 7 years x Rp.1,135,000.00= Rp.7,945,000.00 – Rp.5,000,000.00 (initial investment)= Rp.2,945,000.00. The conclusion that can be drawn that household income from hydroponic cultivation is profitable, with an income value greater than the costs incurred (revenue>cost). Keywords: increased income, hydroponic

Abstract:
The rising world population is posing threats to global food security. The problem is more serious in urban areas where there is scarcity of farming land and water. Further, global warming is making it more and more difficult to plant crops in an uncontrolled environment. In traditional soil based farming method, farmers require good quality of soil with natural minerals. Soil based farming consumes more resources such as water, fertilizers and space. It also requires higher working cost for tilling and removal of weeds. Hydroponic farming is a soilless urban market gardening technique that aims at providing fresh farm products, at low costs mainly in urban areas. It has the potential of alleviating food security challenges. However, this practice requires constant monitoring of the farm environment. Falling prices of advanced microcontroller boards and sensors is making it possible to control and monitor a farm without or with less human intervention. And wireless sensing makes this even more convenient and less messier.

Abstract:
Developing entrepreneurship for the students should be done starting from of primary and secondary education. The major obstacles experienced by the school in general are not the inclusion of entrepreneurial material in the curriculum contained in the school subjects. Similarly, the partner in this case MTs Al Fatah Singkawang. The constraints that the partners of the community service Program are the limitation of capital (cost), human resources, technology and also the location of land that is narrow enough to implement activities for students. Program activities are conducted with hydroponic vegetable cultivation and catfish cultivation with Bioflok technology which is carried out by 30 students MTs Al Fatah and also involve the practitioners of hydroponic vegetable cultivation and also fish farming practitioners Catfish with Bioflok system. This activity was held from May 2019 until December 2019. Hydroponic vegetable farming and catfish cultivation activities with Bioflok technology started with the preparation of cultivation media until the process of cultivation. Results show that students can already practice vegetable cultivation in hydroponics and fish farming with BIOMAXI technology and this activity plays a major role in cultivating the entrepreneurship of students.

Abstract:
Food systems are considered one of the most important anthropogenic activities contributing to climate change. On the other hand, climate change influences the conditions for growth with more frequent droughts and heatwaves. This contradiction poses a significant challenge to future food systems, which need not only become more sustainable, but also increase its production to feed a growing population, as stated in both the United Nations Sustainable Development Goals, and the Swedish action plan on food. This has given rise to alternative ways of producing food, such as urban farming and, in particular vertical hydroponic farming, where food is grown indoors in a controlled environment with artificial lighting and with a minimum use of water and without pesticides. In this study, a vertical hydroponic farm located in Stockholm, Sweden, is examined using life cycle assessment in terms of environmental sustainability. The farm, located in a basement space, works together with the building in a symbiotic network, where the farm provides the building with excess heat from the lighting, and in turn obtains carbon dioxide from an office floor. The findings from the study show that electricity is a major contributor to the environmental performance of the farm, along with the infrastructure employed. The impacts of water use in the farm, is very low, along with the impacts associated with the delivery of the crops; illustrating the advantages of producing food locally. By substituting the synthetic fertilizers employed to biofertilizers, and by substituting the plastic bag material to renewable material, reductions in greenhouse gases are possible. The symbiotic development between the farm and the building is shown very beneficial to the farm, highlighting the importance of synergies between actors in urban areas.
Livsmedelsindustrin anses vara en av de största antropogena drivkrafterna bakom klimatförändringarna. Å andra sidan så förändrar klimatförändringar i sig förutsättningarna för hållbar odling, med mer frekventa torrperioder, extrem värme och extrem nederbörd. Denna konträra situation ställer stora krav på framtidens livsmedelsindustri, som dessutom måste producera mer mat för att mätta en ökande befolkning; ett åtagande som står angivet både i FN:s globala mål och i den svenska Livsmedelsstrategin. Många forskare menar att dagens livsmedelsindustri inte kommer klara denna omställning, och att alternativa metoder för att producera mat behövs. Urban odling har föreslagits som en del av lösningen, och i synnerhet vertikal hydroponisk odling där grödor växer inomhus i en kontrollerad miljö med artificiell belysning, låg vattenanvändning och utan bekämpningsmedel. Den här studien undersökte en vertikal hydroponisk odling i Stockholm, och bedömde dess miljömässiga hållbarhet med hjälp av en livscykelanalys. Odlingen, som sker i en källarlokal, samarbetar med den omslutande byggnaden i en urban symbios, där odlingen förser byggnaden med spillvärme från belysningen, och får i sin tur koldioxid från en kontorslokal. Enligt resultat från studien bidrar elektriciteten till den största miljöpåverkan, men även infrastruktur har stor påverkan. Vattenanvändningen i odlingen är däremot väldigt låg, och miljöpåverkan från leveransen av varorna är mycket låg, vilket belyser fördelarna med att odla mat lokalt. Odlingen kan bland annat minska sin miljöpåverkan genom att byta ut det nuvarande konstgödslet till biogödsel och genom att byta ut plastpåsarnas material till förnybar plast. Symbiosen mellan odlingen och byggnaden visade sig vara väldigt gynnsam, vilket vidare belyser vikten av samspel mellan olika aktörer i den urbana miljön.

Abstract:
Sustainable alternatives to using mined nutrients in agriculture must be found in order to limit environmental impacts such as eutrophication, habitat destruction and greenhouse gas emis-sions. Biogas slurry and urine recycled to hydroponic food production (a type of soilless agri-culture) have the potential of providing inorganic nitrogen and phosphorus, the main essential nutrients required for plant growth. A Life Cycle Inventory Assessment (LCI) methodology has been used to compare the systems of producing artificial fertilizer, biogas slurry and urine based nutrient solutions for the growth of Brassica rapa L. (Chinese cabbage) in the context of a large scale hydroponic vertical farm. Costs and energy requirements have been the basis of the comparison and results show that both biogas slurry and urine are considerably cheaper than the commercial alternative and based on the nutrient content they have the potential of being successful nutrient solutions after dilution and nutrient supplementation. Filtration might also be required in order to remove suspended particles and pathogens.

Abstract:
Many studies have investigated the issue of feeding the world’s growing population from different perspectives. Conventional agricultural methods usually have small production yields while requiring large amounts of scarce and unevenly distributed resources such as farmland and water. Furthermore, although produced food may meet the demands, it is still inefficiently delivered among different regions. Urban agriculture has been proposed to produce food inside urban areas with higher yields and less resource consumption. Hydroponics is one of the urban farming methods that needs further research before being applied on large scales. This study aims to investigate the potential lettuce production using hydroponic systems to grow lettuce domestically in urban areas in Sweden to lower its lettuce import and motivate local food production to become self-sufficient. The study is performed using a literature review, theoretical design of a system, and scenario-based assessment of hydroponic lettuce production. The detailed analysis is performed via a case study of lettuce production in Uppsala municipality and two scenarios considering the reduction of lettuce import to Sweden and related challenges and opportunities of the designed system. The analyses demonstrate that the system paves the way to decrease lettuce import and dependence on trade. Therefore, applying the system increases self-sufficiency and decreases vulnerability to shocks. Nevertheless, the study does not necessarily address issues related to transportation and food miles. Moreover, finding suitable places to establish the system needs further studies.

Abstract:
The world is facing a food shortage as the world’s population increases and arable land decreases. Despite this, the food industry is wasteful, and 30% - 40% of all produced food is lost before reaching the end consumer. Emerging technologies aim to increase the amount of food that can be grown per m2 or allow the growing of food in climates or on lands previously impossible. Four main farming techniques utilising these emerging technologies are Controlled Environment Agriculture, Hydroponic Farming, Urban Farming and Vertical farming. When used together, these techniques form the basis for what can be called a Plant Factory. Despite the positive effects these technologies have on the production rate, few Plant Factories have managed to achieve profitability. By creating support for developing the post-harvesting system for a plant factory, this thesis aims to aid in the development of profitable plant factories. The thesis uses Design Research Methodology to achieve this aim in three parts. The first part identifies the underlying factors of the post-harvesting system affecting plant factory profitability. The second presents a set of support components that will aid the developers to improve key factors affecting profitability. The third part is a case study where the support components applicability at targeting the key factors are evaluated, and suggestions for further improvements and testing of the support is suggested.  Further, using Design Research Methodology, the methods used to develop support in this thesis are presented to easily be replicated by other researchers to aid them in developing support for other industries and circumstances. The suitability of the developed support was tested using the principles of an initial DS-II. The developed support proved very useful for the investigated case, and with its conditions, the application evaluation was considered a partial success. Two key factors were successfully improved and indicated that the intended support is ready for a comprehensive DS-II. A third support component needs more work to provide the intended support fully. Therefore a second  PS iteration is recommended before a comprehensive DS-II is done to increase its value.

Abstract:
Vertical farming has been proposed as a solution for providing food security for an increasing, urbanized human population. Light-emitting diode (LED) technology has become increasingly affordable and efficient, making it an ideal choice as artificial lighting for indoor farms. Still largely undiscovered parameters are the optimal plant varieties and types of production systems for plant growth, profit, and human nutrition. Aquaponics may be able to provide sustainable animal protein for vertical farms, increasing their ability to provide more substantial nutrition to consumers. This research aimed to better understand vertical farming as a food production system, and to determine if aquaponics can be an appropriate and applicable fit for it. The experiment was a randomized, factorial design with three independent variables: (1) LED photoperiod interval (2) LED-plant distance, and (3) nutrient solution, as well as several dependent variables to assess both plant yield and quality. A 4-tiered shelving unit was constructed for nutrient film technique (NFT) plant production, and treatments were assigned to each row: (1) LED experiment: Row A, 12/12hr reduced photoperiod with adjustable LEDs 4in. above plant surface; Row B, 2/1hr altered photoperiod interval relative to the control; Row C (control), 16/8hr “standard” photoperiod. (2) Nutrient experiment: Row C, aquaponic nutrient solution; Row H, hydroponic nutrient solution. Rows C and H had matched photoperiod and light intensity. Kale from Row A had significantly lower fresh and dry plant yield relative to the control, Row C (p<0.05). Hydroponic romaine, Row H, had significantly higher plant yield relative to aquaponics, Row C (p<0.05). Butterhead yields were not significantly different in any treatments (p>0.05). Future research may implement a larger sample size of only one plant variety, harvest plants earlier, limit light intensity variation, effectively “balance” the aquaponics system, and have more measures of plant “quality.”

In the conventional and hydroponic cultivation of lettuce, agricultural defensives and fertilizers are used, which presents concentrations of toxic elements in its composition and may alter the aliment’s quality. Thus, the present study aims to evaluate the content of the heavy metals Cd, Cr, Cu and Pb in soil, nutritive solution and lettuce leaves in the region of Toledo – PR. Samples of lettuce and its substrates were collected from five hydroponic and five conventional proprieties, which were submitted to nitroperchloric digestion for the determination of metal contents through spectrophotometry of atomic adsorption AAS/6300. The experimental delimitation was entirely randomized, with ten treatments and three repetitions, and the results were submitted to variance analysis and to Turkey’s test at 5% significance level; also, the Pearson’s correlation (r) was performed between the variables substrate and lettuce leaves. It was observed that the lettuce studied, in general, presented higher contents of Cd and Cr in the hydroponic cultivation - in which 5 of the hydroponic proprieties, 4 of them presented significantly superior than the conventional ones - according to the Turkey’s test; for the element Cu, significant difference also occurred between the farming methods, however there was significant variance in the cultivation of each property; and for Pb, it was observed that the majority of the samples collected presented higher concentrations than the tolerable limits established by ANVISA - whereas the conventional method presented itself statistically similar between each property, for the hydroponic method, two properties presented themselves significantly superior to the others, and statistically different between each other. When the metal concentrations in the lettuce leaves was compared with the substrate, in general, for both conventional and hydroponic methods the contents in the lettuce didn’t show correlation to the contents in the substrate, which indicate that the contamination may be occurring through the use of agrochemicals and agricultural inputs, used for the control of plagues and diseases, aside from inappropriate management. Thus, it is possible to conclude that the variation in metal concentrations in the same cultivation method is due to the fact that the use of different agrochemicals and fertilizes is allowed, which contain different compositions. Furthermore, the pulverization date previous to sampling of the lettuce may have caused some variations to the composition of the vegetable, as well as inappropriate handling of the aliment.
Nos cultivos de alface convencional e hidropônica são utilizados defensivos agrícolas e fertilizantes, que apresentam concentrações de elementos tóxicos em sua composição e podem alterar a qualidade do alimento. Dessa forma, o presente trabalho objetivou avaliar os teores dos metais pesados Cd, Cr, Cu e Pb em solo, solução nutritiva e folhas de alfaces na região de Toledo – PR. Foram coletadas amostras de alfaces e de seus substratos em cinco propriedades hidropônicas e cinco convencionais, cujas amostras foram submetidas à digestão nítrico-perclórica para determinação dos teores de metais por meio de espectrofotômetro de absorção atômica AAS/6300. O delineamento experimental foi inteiramente casualizado, com dez tratamentos e três repetições e os resultados foram submetidos à análise de variância e ao teste Tukey ao nível de 5% de significância; ainda foi realizada a correlação de Pearson (r) entre as variáveis substrato e folhas de alface. Observou-se que as alfaces estudadas em geral apresentaram maiores concentrações de Cd e Cr no cultivo hidropônico, sendo que dos 5 cultivos hidropônicos, 4 deles mostraram-se significativamente superiores ao cultivo convencional pelo teste de Tukey; para o elemento Cu, também ocorreu diferença significativa entre os cultivos, no entanto houve uma grande variação entre as culturas e para o Pb, observou-se que a maioria das amostras coletadas apresentavam concentrações superiores ao limite tolerável estabelecido pela ANVISA, sendo que o cultivo convencional mostrou-se estatisticamente semelhante entre si; quanto aos cultivos hidropônicos, dois cultivos mostraram-se significativamente superiores aos demais, e estatisticamente diferentes entre si. Quando comparadas as concentrações de metais nas folhas de alface com o substrato, de forma geral, tanto para o cultivo convencional, quanto para o cultivo hidropônico os teores na alface não apresentaram correlação com os teores no substrato, o que indica que a contaminação pode estar ocorrendo através do uso de agrotóxicos e insumos utilizados para o controle de pragas e doenças, além do manejo inadequado. Assim, pode-se dizer que a variação nas concentrações de metais na mesma cultura deve-se ao fato de ser permitido o uso de diferentes agrotóxicos e fertilizantes, os quais possuem composições distintas. Além disso, a data de pulverização previamente à coleta das alfaces pode ter ocasionado algumas variações na composição da hortaliça, bem como o manejo inadequado do alimento.

Abstract:
Denna rapport behandlar en fallstudie i ett kandidatexamensarbete som utförts tillsammans med en livsmedelsbutik i Stockholmsområdet och som grundar sig i intervjuer, platsbesök och vetenskapliga artiklar. Där livsmedelsbutiken har ett intresse av att implementera en odling i form av ett hydroponiskt system direkt i sin butik.  I fallstudien har det undersökts hur implementering av odling i butik genom ett samarbete med ett odlingsföretag skulle fungera och se ut för butiken. Studien har begränsats till två olika odlingsföretag i Sverige, som har varsitt koncept på hur odlingen kan implementeras, gemensamt för dem är att de använder vertikal odling i form av hydroponiska system. Där det ena företaget erbjuder vertikal odling i en odlingscontainer och det andra vertikal odling inne i ett växthus. Båda företagens olika odlingskoncept har redan implementerats i två andra livsmedelsbutiker inom samma koncern som livsmedelsbutiken i Stockholm befinner sig i.  Fallstudien har genomförts genom att först skapa en bred bakgrund genom litteratursökningar i olika databaser kring relevanta nyckelord för att sedan genomföra intervjuer med båda odlingsföretagen och livsmedelsbutikerna. Därefter har kunskap och svar från respondenterna i intervjuerna sammanställts och ett förslag har tagits fram om vilket odlingsföretag som lämpar sig bäst för livsmedelsbutikens ändamål.  Resultatet visar att möjligheterna och fördelarna vid en implementering av hydroponisk odling för livsmedelsbutiken i Stockholmsområdet att implementera hydroponisk odling är flera och överväger till största del de möjliga utmaningarna. Dessutom gynnas flera av hållbarhetsmålen till livsmedelsbutikens koncern genom implementering av en hydroponisk odling i butiken. Vidare gynnas även några av de Förenta Nationernas Globala mål och även livsmedelsbutikens egna hållbarhetsmål.
This report is the result and outcome of a bachelor's thesis project conducted during the spring of 2021. The report presents the performed case study of a grocery store, in the area of Stockholm, where the company is aiming to implement a hydroponic self-cultivation inside their grocery store. The work is based on conducting interviews and reviewing established scientific articles in the field.  In the case study, it has been investigated how a potential collaboration between the grocery store and a cultivation company can be established. The study was limited to investigating two cultivation companies active on the Swedish market. These two cultivation companies have different solutions of how the cultivation can be implemented on the store area, but both offer vertical hydroponic solutions. Further, both systems of the individual cultivation companies’ have been implemented in other grocery stores that can be used as reference for validation of data.  The literature review of existing publications were conducted by searching in different databases by using the keywords of this work, for the researcher to increase knowledge to create guides for the interviews and for creating the theoretical frame of reference. Thereafter, literature findings and answers from the interviewees were compiled, analyzed and discussed to make a proposition of which cultivation company is best suited for a potential collaboration, with regard to the grocery stores’ wishes of implementing a hydroponic solution.  The results show that several of the grocery stores’ sustainability goals would benefit from a potential implementation of a self-cultivation. Also, implementing a hydroponic farm on the store area would increase the grocery store’s contribution towards achieving the Sustainable Development Goals.

Abstract:
The purpose of this project is to make it easier to grow plants domestically all year round. The objective is to construct a remotely controllable and environmentally independent automated hydroponic system. This would minimize the efforts required by the user to sustain plants in non-native climates. A hydroponic gardening system uses water as a growth medium instead of soil. The system is climate conscious and has benefits compared to conventional agriculture. Hydroponic systems are affected by several factors, this project only focuses on controlling the light intensity by isolating the system, and regulating the nutrient concentration through EC. The system uses a microcontroller for analysis and control. The results are promising, showing that the system works. However, the limitations in time led to a short test period, therefore the data gathered is limited. The discussion based on the results conclude that the system cannot be considered completely automatic but reduces the need of manual labour.
Syftet med detta projekt är att göra det lättare att odla växter inhemskt året runt. Målet är att konstruera ett fjärrstyrbart och miljöoberoende automatiskt hydroponiskt system. Detta ska minimera ansträngningarna från användaren för att underhålla växter i icke-inhemska klimat. Ett hydroponiskt odlingssystem använder vatten som tillväxtmedium istället för jord. Tekniken har fördelar jämfört med konventionell odling vilket gör hydroponi mer miljövänligt. Hydroponiska system påverkas av flera faktorer, men detta projekt fokuserar bara på att kontrollera ljusintensiteten genom att isolera ljuset inom systemet samt att reglera näringsämne-koncentrationen genom att mäta den elektriska ledningsförmågan i vattnet. Systemet använder en mikrokontroll för analys och kontroll. Resultaten är lovande och visar att systemet fungerar. Däremot har begränsningarna i tid lett till en kort testperiod, därför är data som samlas in begränsad. Diskussionen baserad på resultaten drar slutsatsen att systemet inte kan anses vara helt automatiskt men reducerar behovet av manuell arbetskraft.

Abstract:
Experiments were conducted with tomato under shade netting and with lettuce in a vertical hydroponic system at the Hatfield Experimental Farm, University of Pretoria. The objectives of the study were: 1. To evaluate the effect of different types of shade netting on tomato production 2. To develop a vertical hydroponic system for lettuce production which would be suitable for use by small-scale farmers. In the tomato trial the highest number of fruit per plant (47) was produced under 12% white shade and 40% black shade nets, and the lowest fruit number (35) was produced under 30% black net. The highest yield of 6.2 kg per plant was obtained under the 18% white net while 30% black net produced the lowest yield of 3.9 kg per plant. The test yield of lettuce grown in plastic tubes with eight vertically arranged plant positions were obtained with a continuous high flow rate of the nutrient solution. However, a simplified manual system where the nutrient solution was delivered by gravity from a small reservoir tank resulted in comparable yields.

Abstract:
This paper examined how Change Management and Transformational Leadership can be effective tools in transitioning towards sustainable agriculture in Europe. This paper starts with providing empirical evidence for climate change and shows that Northern and Southern Europe are impacted differently by climate change. Then this paper examined how climate change affects farmers in the different parts of Europe and what Societal, Environmental, Leadership and Organisational changes have to be made to transition towards sustainable agriculture in Europe. The qualitative analysis shows that, according to farmer associations, there is a need for a variety of options, a lack of communication and insufficient involvement of farmers on a policy making level. This paper ends with explaining how Change Management and Transformational Leadership can be used as tools to improve communication between stakeholders and improve the involvement of farmers in the co-creation process. Therefore, this paper concludes that Change Management and Transformational leadership will help the European Union in realising sustainable agriculture in Europe.

Abstract:
Hydroponics farming is fast gaining acceptance globally as an alternative and viable method of farming, instigated by the contemporary challenges posed by climate change, exploding population growth, and global food insecurity. Hydroponics farming can be greatly improved by leveraging on innovative technological advances that will allow for the effective and efficient utiliza-tion of limited natural resources such as water, energy (sunlight), and dwindling agricultural farmlands, consequently resulting in higher yields. This paper presents the design and implementation of an automated flood and drain hydroponic system with internet of things and Android application functionalities. The design is an integrated and automatic plant-watering, water level, and pH measurement and control system using Android application with wi-fi communication technology. Tests carried out proved the worka-bility of the system in line with expected design considerations.

Abstract:
Urban farming is defined as building development for the production of plants for the needs of the local community. The presented issues concern the shaping of urban farms for the preservation of the environmental balance of urban spaces and connections concerning the coexistence of architecture and greenery in the city. This chapter indicates the possibility of shaping synergistic spatial systems by integrating urban space and buildings with an innovative production function—a municipal farm—that complements the functional structure of the city in connection with the shaping of public spaces and the greenery system. The pro-environmental architecture connected with technologies enabling the production of plants in buildings enables the integration of urban space, complementing the functional and spatial structure of the city. The implementation of new technologies enables the production of plants in hydroponic and aeroponic farm buildings. The urban farm is an element in planning the city's sustainable development.

Abstract:
There are two types of soilless cultivation. Liquid systems are the growing of plants in the nutrient solution or under the mist of nutrient solution without a solid substrate. Solid-medium systems use inorganic, or organic materials for the plant roots. The chapter reviews a number of liquid systems: deep water culture (DWC), nutrient film technique (NFT), floating system, deep flow technique (DFT), aeroponics and dry hydroponics. Solid systems described include: gravel culture, sand culture, bag culture, container culture and trough culture. The chapter also assesses aquaponics, bioponics and vertical farming systems. The chapter discusses open and closed nutrition systems before looking at ways of optimising water and nutrient supply: growing medium and solution volume per plant, root zone temperature, oxygen enrichment and plant density. The chapter concludes with a case study on rocket production in liquid and solid medium systems.

Abstract:
It is estimated that the global population will reach approximately 10 billion people by 2050 and 66% of the world population will live in urban areas. This growth in cities creates demand for fresh products to maintain a healthy population, a product that often exposed to a long journey to reach the consumer, not only losing quality and nutritive value in the process, but also requiring a significant cost of fossil fuel for transportation and storage. However, the world’s agricultural land among being limited, is also facing major problems such as pollution, salinization and drought that do not favor crop production. The need for food security has paved the way for landless agriculture, becoming more popular in the urban area and becoming a part of urban farming. This article aims to examine hydroponic technologies to help expand the knowledge of their application in terms of science, origin, dynamics and farming systems. Among the benefits of soilless cultures; reservation of cultivated land for main crops; saving at least 90% of irrigation water; use of almost constant amount of recycled water; successfully growing almost every vegetable crops and having highest productivity compared to conventional agriculture. Therefore, it is an indispensable solution in areas where arable land is not available or in saline-prone areas, in short, wherever there is competition for land and water. The purpose of this study is an overview of soilless farming systems, explaining the most widely used hydroponic system, the importance of water quality, nutrient content, grown crops and ultimately cost benefit in terms of economics.
