Sustainable Business Model Innovation in Vertical Farming Startups : Case Studies of Southeast Asian Vertical Farming Startups / Hållbar affärsmodellsinnovation i vertikala jordbruks-startups : Fallstudier av vertikala jordbruks-startups i Sydostasien

Kelana, Fajar-Sidik-Abdullah January 2022 (has links)
Rapid growing population, urbanization, climate change, decreasing agricultural production, and soil degradation causes massive challenges for food production and supply chain in Southeast Asia, especially in urban areas. A sustainable food production and supply chain system is needed to produce and supply food for Southeast Asia urban areas. One potential solution to those challenges is introducing vertical farming. Vertical farming can produce high-quality crops locally and sustainably by reducing water and land use, decreasing pesticide use, reducing carbon footprint, and growing plants in any climate. This research aims to identify the current status of vertical farming startups in Southeast Asia, investigate the existing challenges and available opportunities in the Southeast Asia vertical farming industry, and analyze the sustainability practices and sustainable business model innovation implemented by Southeast Asia vertical farming startups. A literature review of vertical farming business typology, business model innovation, and sustainable business model innovation is used to create theoretical frameworks in this research. This research is an exploratory multiple case studies research with a qualitative method. The data in this research is collected through interviews with founders and managers from 10 vertical farming startups in Southeast Asia. The interview data is analyzed using vertical farming business typology, business model framework, and sustainable business model innovation archetypes. The research outcomes indicate that the vertical farming industry in Southeast Asia is an early growing industry, and Southeast Asia vertical farming startups are considered as early growing startups with small capital and small teams. Despite existing financial, operational, and market challenges, Southeast Asia vertical farming startups have considerable opportunities to grow with their effort to develop their vertical farming business into a more sustainable business by conducting various sustainability practices and adopting sustainable business model innovation. / Snabbt växande befolkning, urbanisering, klimatförändringar, minskad jordbruksproduktion och markförstöring orsakar enorma utmaningar för livsmedelsproduktionen och försörjningskedjan i Sydostasien, särskilt i stadsområden. En hållbar livsmedelsproduktion och försörjningskedja behövs för att producera och leverera mat till Sydostasiens stadsområden. En potentiell lösning på dessa utmaningar är att införa vertikalt jordbruk. Vertikalt jordbruk kan producera högkvalitativa grödor lokalt och hållbart genom att minska vatten- och markanvändningen, minska användningen av bekämpningsmedel, minska koldioxidavtrycket och odla växter i alla klimat. Denna forskning syftar till att identifiera den nuvarande statusen för vertikala jordbruks-startups i Sydostasien, undersöka de befintliga utmaningarna och tillgängliga möjligheter i den vertikala jordbruksindustrin och analysera hållbarhetspraxis och hållbar affärsmodellsinnovation som implementerats av vertikala jordbruks-startups. En litteraturgenomgång av vertikal jordbruksverksamhetstypologi och hållbar affärsmodellsinnovation används för att skapa teoretiskt ramverk i denna studie. I detta examensarbete tillämpas en kvalitativ forskning med flera fallstudier. Data samlas in genom intervjuer med grundare och chefer från 10 vertikala jordbruks-startups i Sydostasien. Intervjudata analyseras med hjälp av typologi för vertikal jordbruksföretag, ramverk för affärsmodeller och arketyper för hållbar affärsmodellsinnovation. Resultaten indikerar att den vertikala jordbruksindustrin i Sydostasien är en tidig växande industri, med tidigt växande startups med litet kapital och små team. Trots befintliga ekonomiska, operativa och marknadsmässiga utmaningar har vertikala jordbruks-startups i Sydostasien stora möjligheter att växa med sina ansträngningar att utveckla sin vertikala jordbruksverksamhet till en mer hållbar verksamhet genom att bedriva olika hållbarhetsmetoder och införa hållbar affärsmodellsinnovation.

Implementering av hydroponisk odling i en livsmedelsbutik : En fallstudie av en aktör inom Stockholmsområdet / Implementation of hydroponic cultivation in a grocery store : A case study of an actor in the Stockholm area

Korssell, Caroline, Rudert, Emelie January 2021 (has links)
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.

Assessing the adaptive capacity of Sweden's environmental governance

Tomas, Cusicanqui January 2016 (has links)
Different challenges arising from increasingly uncertain and unpredictable environmental and economicconditions have been shifting the focus of public governance and socio-economic development. Morerecently, empirical studies have demonstrated a transitional epoch in which humanity is currently in: TheAnthropocene, as well as its harmful effects that degrade the biosphere, and thus our economic, political,social well-being. The casual dynamics of climate change and its impacts on life-supporting ecosystemshas increasingly been recognized by a resilient approach which incorporates adaptive processes andschemes, allowing public governance to embrace the changes rather than control uncertainty. Thisresearch introduces the interwoven concepts of adaptive capacity, adaptive governance, and resiliencewithin a social and environmental framework. It provides a review of how these concepts support aparadigm shift to mitigating current and future challenges—understood through a multidisciplinaryapproach, and how scholars have sought to develop a blueprint to improve the need to foster and mobilizeadaptive capacity within the governance of the commons. In Sweden, key governmental and businessleaders have shown the ability to foster environmental governance that is capable of developing analternative form of planning, implementing, and managing public policy. Moreover, Sweden’s concertedmultilevel governance and public policy efforts have promoted an all-encompassing generational, mainlythrough: coordinated environmental policies and private, public, and civil society partnerships. Theseinitiatives have led to innovative technologies and projects (e.g. urban vertical farming technology) as wellas cross collaboration and integration of companies and industries in order to achieve economic, social,and environmentally symbiosis.

Sustainable urban agriculture and forestation : the edible connected city

Durant, Valerie A. 12 July 2013 (has links)
Current global agricultural practices are recognized as unsustainable. The increase in overall human population as well as the global trend of rural to urban migration, partially as a result of historically and continual unsustainable agricultural practices, exacerbates the vicious cycle of poverty and hunger in developing countries. Furthermore, cities and regions in developed countries practice unsustainable food production, distribution and consumption patterns, and as a result, exceed their global ecological footprint (Rees 2009). Consequently, the world is facing a global food (FAO 2009) and water crisis (UN Sick Water 2010). Cities and Regions must learn to feed themselves to address local food insecurity as well as protect from the climate effects of increased urbanization, including the Urban Heat Island effect (UHIe) by optimizing and fully integrating the local ecosystem services of food, water and forest within a tightly woven compact urban form through the implementation of strategic urban and regional food system planning. Cities can mitigate climate change and reduce the UHIe, by implementing sustainable intensive urban agriculture approaches through policy and zoning interventions that include concepts such as intensively productive urban agriculture that includes green roofs, vertical farming and greenways as continuously productive and edible urban landscapes, referred to in this paper as continuously productive urban agriculture and forestation (CPUAF) in the private and public realm. A highly participative, adaptive systems approach is explored as the key to sustainability within an economic world order that included corporate social responsibility and social enterprise as the foundation for the integration of multiple synergies. An increasing body of evidence often links urban forestation with urban greenery initiatives, as a carbon sink to reduce UHI effects, to reduce GHG emissions and as a tool for urban beautification and place making (ISDR: 2009,109). Urban agriculture, through the production of local food is increasingly recognized as a means to reduce fossil fuel emissions by reducing transportation and production outputs, to provide a secure local food source, enhance biodiversity and educate the public regarding food source while fostering a sense of community, environmental awareness and stewardship. This thesis explores the links between intensive urban agriculture and forestation, and the relationship between climate change, and the UHI’s as an adaptation and mitigation process in global cities, implemented as a interconnected, integrated, holistic urban management approach that has a further benefit of providing food security and a sustainable and local urban food source. / Dissertation (MTRP)--University of Pretoria, 2012. / Town and Regional Planning / unrestricted

Empowering Smallholder Farmers to Achieve Food Sovereignty Through Soil-Less Agriculture

Balasubramanya, Abhijith Nag, Shaafiu, Fathimath Zainy January 2022 (has links)
This study explores the question of how soil-less agriculture through hydroponics, aeroponics, and aquaponics can empower smallholder farmers to achieve food sovereignty as portrayed in documentaries. It addresses the power imbalance between large corporations and smallholder farmers in the traditional agriculture industry. Documentary research approach is used to understand the various applications and research aspects of soil-less agriculture from around the world. Real-life examples from different countries where these methods have been successfully implemented in the agriculture industry, ranging from large industrial settings to smallholder farmers in disadvantaged communities, are analyzed. Further, content analysis is done on these documents by constructing a matrix that combines the process of empowerment and the six pillars of food sovereignty to analyze the different forms of empowerment. The study also investigates how the use of soil-less agriculture can build capabilities through enhanced “well-being freedom” and “agency freedom” and empower smallholder farmers to achieve food sovereignty.

Co-simulation for controlled environment agriculture

Archambault, Pascal 08 1900 (has links)
Thèse produite en partenariat avec la Ferme d'hiver, centre de recherche industrielle pour l'agriculture en environnement contrôlé. / L’agriculture en environnement contrôlé (AEC) est une pratique agricole de haute technologie où la culture de plantes et son environnement sont soumis à une certaine forme de contrôle afin d’obtenir des rendements plus élevés et une efficacité de production accrue. L’AEC est essentielle en raison de son impact sur la disponibilité des terres arables, l’utilisation de l’eau et l’efficacité énergétique face à l’augmentation de l’insécurité alimentaire mondiale. Les systèmes de AEC sont contrôlés par le biais d’indicateurs de performance clés (IPC) complexes que les experts de plusieurs domaines, dont les ingénieurs et les agronomes, doivent optimiser. L’optimisation des IPC nécessite l’exploration de l’immense espace d’états du système d’AEC. Étant donné que ces systèmes sont complexes et hétérogènes, ils nécessitent une approche de modélisation et de co-simulation multi-paradigme dans laquelle les modèles utilisent les formalismes et les niveaux d’abstraction les plus appropriés. Nous proposons une architecture de co-simulation de AEC capable de capturer la dynamique des entités qui composent notre système à plusieurs niveaux d’abstraction. Nous présentons nos résultats démontrant la validité de notre approche / Controlled environment agriculture (CEA) is a high-tech agricultural practice where the crop and its environment are subject to some form of control to achieve higher yields and produc- tion efficiency. CEA is critical for its impacts on arable land availability, water usage, and energy efficiency amid the rise of global food insecurity. CEA systems are controlled through complex key performance indicators (KPI) that experts of multiple domains, including engi- neers and agronomists, must optimize. The optimization of KPI requires exploring the vast state space of the CEA system. As such systems are complex and heterogeneous, they re- quire a multi-paradigm modeling and co-simulation approach in which models use the most appropriate formalisms and levels of abstraction. We provide a co-simulation architecture for CEA to capture the dynamics of the entities that comprise our system at multiple levels of abstraction and present our results showing the validity of our approach.
