Abstract

:
Demographic, economic, and environmental issues, including climate change events, aging population, growing urban-rural disparity, and the COVID-19 pandemic, contribute to vulnerabilities in agricultural production and food systems. South Korea has designated smart agriculture as a national strategic investment, expanding investment in research and development (R&D) to develop and commercialize convergence technologies, thus extending sustainable smart agriculture and strengthening global competitiveness. Hence, this study probes the status of smart agricultural R&D investment from the perspectives of public funds, research areas, technologies, regions, organizations, and stakeholders. It examines 5646 public R&D projects worth USD 1408.5 million on smart agriculture in 17 regions and eight technology clusters from 2015 to 2021. Further, it proposes a pool of potential collaborative networks via a case study of strawberry, a representative veritable crop inspiring smart agriculture, to demonstrate the study framework’s usefulness in promoting smart agriculture and establishing a sustainable R&D collaboration ecosystem. The proposed framework, accordingly, allows stakeholders to understand and monitor the status of R&D investment from various perspectives. Moreover, given the insight into the tasks belonging to technical areas and regions that require sustainable cooperation in smart agriculture, central and local governments develop policies to reinforce sustainable smart-farming models.

1. Introduction

Short and long-term environmental challenges—including climate change events, high energy costs, limited water and arable land, the continuing outflow of farmers, and the COVID-19 pandemic—have contributed to disproportionate vulnerability in agricultural production and food systems, thereby increasing the risk to global and national food security [1,2,3]. In response to such multifaceted challenges, multiple governments, such as the EU, the US, Japan, and South Korea (Korea hereafter), have established national policies to digitally transform the agricultural sector through better alignment of financial investment and institutional arrangements for long-term resilience and sustainability [2]. This concept, expressed through different terms, including smart farming, precision agriculture, precision farming, digital agriculture, and agriculture 4.0, aims to strengthen the efficiency of agricultural activities by adopting smart systems that provide operational solutions based on data from agricultural production [4].
First, in the EU, the European Commission presented legislative proposals in June 2018 for a new common agricultural policy (CAP) to outline a more efficient policy that supports the digital transformation/shift to precision and smart farming, thereby ensuring more economic competitiveness and simultaneously safeguarding the environment [5]. The new CAP can be implemented by investing massively in ambitious EU programs for research and development (R&D) projects that boost photosynthesis for food and energy, make precision farming techniques available to small farmers, encourage the sustainable use of land to improve soil health and consider sustainable aquaculture approaches [6].
Second, in the US, the private industry and universities or state cooperative extension specialists are the main drivers of advancing agricultural technologies and information systems for precision agriculture or smart farming. Therefore, a national policy for smart-farming solutions does not exist [1]. However, a current national agricultural and food policy worth USD 428 billion, commonly known as the “2018 Farm Bill” [7], has been made applicable from 2018 to 2023. This policy focuses on the investment in infrastructure to expand broadband Internet access to rural areas; it facilitates precision agriculture technologies, thereby improving productivity and profitability for small farmers [8].
Third, in June 2016, the government of Japan targeted agriculture as a key area for structural reform under the “Japan Revitalization Strategy” to transform the farm sector into a profitable industry by promoting smart agriculture and digital transformation [9]. Further, the government has made concrete efforts to implement the plan by investing in national programs and projects for innovation to assemble various key players to achieve interdisciplinary cooperation in data acquisition systems and analysis and agricultural robot solutions. Moreover, support for several projects across Japan, including paddy rice production, field and greenhouse cultivation, fruits, tea, and livestock, demonstrates the practical use of the latest smart-farming technology and solutions [10,11].
Fourth, the Korean government also addressed the national agricultural and food policy under two five-year comprehensive plans to develop science and technology for agriculture, forestry, and food for 2014 (second plan for the 2015–2019 period) [12] and 2019 (third plan for the 2020–2024 period) [13]. In 2018, the new president emphasized the need to cultivate smart farming as one of eight national strategic industries [14] and proposed a series of national smart-farm strategies, such as the Smart Farm Expansion Plan [15], comprehensive measures to extend smart agriculture based on big data and artificial intelligence (AI) [16], and the 2050 Agri-food Carbon Neutral Promotion Strategy [17].
These governments have a vested interest in pursuing sustainable agriculture as a facet of sustaining national security and natural resources. They emphasize productivity-enhancing technologies, such as mechanization and digitized farming and food systems, as essential in protecting against environmental degradation and supporting agricultural and climate-smart technologies [2,8,18]. However, Korea differs from industrialized countries and regions such as the US, EU, and Japan [8], as it has less cultivated land for agriculture, a high proportion of small-sized subsistence farming [19], and a horticulture facility and livestock-centered smart-farming policy [20]. Korean research stresses the normative argument that policies to strengthen national smart farming should focus on a comprehensive public fund strategy during decision-making [21,22]. Thus, it is necessary to understand the current public investment situation to establish a better Korean smart-farming policy or strategy, specifically from a technological perspective.
Most studies on applications of smart-farming solutions primarily focus on the technical aspects of applying relevant technologies to improve agricultural practices and productivity and post-farmgate processes, such as postharvest quality monitoring in the logistic process and real-time traceability [4]. Meanwhile, recent conceptual and empirical studies on smart farming within social science and policy probe and provide important research streams, including the adoption of smart farming-related technologies on farms, their impacts on farming methods, impacts of digitalized supply chains, and changes in the rules and institutions of the agricultural production systems [4]. However, studies on systematic public investment and the collaboration-related information framework for smart farming in policymaking remain absent. Thus, it is essential to reduce conflicts among different stakeholder types, such as advisors, policymakers, and researchers, contributing to the sustainable development of agriculture, food systems, and rural areas [23].
Therefore, this study investigates the status of smart farming in Korea regarding public funding, organizations, and regions. It (1) reviews the Korean national agricultural policies and describes the challenges therein; (2) reviews the literature on the information framework for smart farming; (3) suggests the development of an information framework using a relevant data-based machine learning technique, and identifies research areas on smart farming that can be foundational to providing insights for better funding allocation and regional collaboration of smart farming; and (4) provides insights and examples to support better smart farming policies.

1.1. Background and Literature Review

1.1.1. Background of Smart-Farming Policies in Korea

The demographic changes in Korea have significantly influenced Korean agriculture. Amid the slowdown of economic growth since the 2010s, rural communities have faced serious challenges given insufficient human resources caused by population aging, reduction in youth influx, and growing disparity between urban and rural areas. For example, almost 60% of farmers are over 65 years old, and their average age is expected to increase [24]. Given such challenges, the agricultural policy focuses on directions to technologically improve the productivity and competitiveness of agriculture [1]. In 2015, the government unified the smart-farm implementation system previously operated by several divisions of the Ministry of Agriculture, Food and Rural Affairs (MAFRA); it then formulated a national plan to develop information and communications technology (ICT)-based high-tech farming.
In December 2014, the MAFRA announced the 2nd Comprehensive Plan to develop science and technology for agriculture, forestry, and food (2015–2019) to reinforce public investment in 50 core strategic technologies in four key research areas. These areas include (1) advanced agricultural and forestry machinery technology, (2) intelligent precision agriculture production realization technology, (3) profitable plant factory business model development, and (4) intelligent agricultural water integrated control systems. The Plan aims to gain global agricultural competitiveness [12]. Under this plan, the goals of smart farming in its three advanced stages are as follows:
  • First stage (2015–2018): Convenience improvement (more convenient and remote control)
  • Second stage (2019–2020): Productivity improvement (less input and more automatic control of water supply and temperature according to the set environment)
  • Third stage (2021–): Sustainability improvement (anyone can operate a farm with AI-based on high production and high-quality accumulated data)
In April 2016, the MAFRA showed the direction of measures to broaden the scope and accelerate the extension of the smart farming concept. Accordingly, the scope of smart farming expanded from greenhouses and livestock to orchards, open fields, and plant factories [25]. In November 2017, the new cabinet selected smart farming as one of eight strategic investment sectors for innovative growth. In April 2018, the MAFRA ambitiously announced the Smart Farm Expansion Plan [15] and proposed the Smart Farm Innovation Valley as a base to ensure synergy between farmers, companies, universities, and research institutes by combining technological innovation, market developments, and youth start-ups [26]. The areas for Phases 1 (Gimje and Sangju) and 2 (Miryang and Goheung) were selected in August 2018 and March 2019, respectively (see Figure 1) [27].
In December 2019, MAFRA announced the 3rd Comprehensive Plan to develop science and technology for agriculture, forestry, and food (2020–2024). It selected five key research areas and 12 core strategic technology areas. This plan emphasized strengthening R&D activities to improve productivity and promote the agri-food value chain [13]. Moreover, in December 2021, the Korean government announced comprehensive measures to extend smart agriculture based on big data and artificial intelligence (AI) [16].
Jang and Kim [28] suggest the following directions for better smart-farm policies: (1) From the technological perspective, smart-farm device technologies should be localized to enhance compatibility by focusing on developing complex environment controller technology, which is the core of smart-farming equipment. Governments should further establish a platform for the market linkage of smart-farming equipment, development of strategic alliance and localization technologies, and development of strategic alliances between domestic companies. (2) From the organizational perspective, there should be collaborative governance between farmers, universities, research institutions, and central and local governments to develop advanced technology in the agricultural sector and strengthen the capacity and role of participants that meet market demands. Thus, Smart Farm Innovation Valley projects will have a significant ripple effect on the agricultural sector and local economy.
As noted, the concept of smart farming is expressed via multiple terms, a mixture of which is found in several national plans in Korea. Particularly, given that the government expanded smart farming from facility horticulture and livestock industry to open-field agriculture in 2019 [20], the Korea Institute of Science & Technology Evaluation and Planning [25] defines smart agriculture as including precision agriculture, smart farming, and digital agriculture from the Korean agriculture perspective. Even so, it does not cover the digitalization of the agri-food supply chain. Therefore, this study redefines the concept of smart agriculture in Korea as follows:
  • Smart agriculture aims to prepare a sustainability strategy for agriculture in response to factors such as climate change crises, food crises caused by population growth, limited resource utilization, and carbon emission. It employs advanced ICT (AI and big data) to improve agricultural productivity and quality, remotely or automatically manage the cultivation environment of crops and livestock and reduce the labor force via a national innovative growth strategy for sustainable future agriculture.
  • Precision agriculture is the oldest agricultural concept and includes technology for detailed monitoring of farmland and water supply and nutrients in the right place. The core technology of precision agriculture is open-field farming, which involves the cultivation of food crops, vegetables, and fruit trees.
  • Smart farming is a core technology of facility farming, including plant gardening facilities, such as greenhouses and plastic houses, livestock facilities for mass breeding of livestock, and plant factories that are closed plant cultivation facilities using artificial light. Smart-farm technology includes technologies to monitor the growth and breeding environment of crops and livestock in facility farms using the Internet of things (IoT), big data, and AI and make optimal farming decisions.
  • Digital agriculture includes technology that collects, analyzes, and shares data on the agriculture and livestock industry and traces the entire process of production, processing, logistics, distribution, and consumption. Digital agriculture can be largely divided into fields such as digital agriculture data platform; digital agriculture distribution, logistics, and consumption; and data solutions and service technologies. For distribution and logistics in the agricultural and livestock industry, various ICTs such as big data, IoT, AI, and cloud computing are combined to implement a smart production and logistics system and smart shops. Figure 2 depicts these concepts.

1.1.2. Theoretical and Empirical Literature Review

In policymaking, decision-makers must adopt approaches to reduce uncertainty by gathering information to achieve analytic comprehensiveness of the targeted domain [29]. Thus, policy scholars focus on building a more comprehensive framework to understand the situation wherein stakeholders face uncertainty related to the content of a decision or policy issue [30]. Apparently, uncertainty in decision-making is associated with three knowledge attributes: incompleteness of knowledge, unpredictability from the complex interaction, and diverging frames of knowledge. Arguably, in principle, epistemic uncertainty from the incompleteness of knowledge can be reduced by collecting more information. Therefore, studies on uncertainty focus on bridging the lack of knowledge by developing a systematic framework [30]. Given the increasingly complex networks of public and private actors who influence the decision-making process, general approaches that allow for bridging the gap between the goals and reality are considered. Here, the assumption is that a shared consensus about the situation and its implications harmonizes the different stakeholder perspectives and enhances public confidence by increasing communication [31]. Further, in the policy development process, situational analysis is recognized as an important phase that defines the noted gaps between the goals-needs and the capacity to reliably deliver quality services and products by providing information and implications about the historical evolution and current status of a topic or issue [32]. Moreover, Cash et al. [33] emphasized that information should have three attributes—salience, credibility, and legitimacy—if it is to be used in decision-making.
Several scholars on environmental sustainability [34,35,36,37,38] and healthcare and wellness sustainability [39,40,41,42,43,44,45] suggest the need for an information framework for decision-making in funding or policy development. In general, these studies provide an evidence-informed decision-making framework. They explore the implications or value of a comprehensive and multiple-perspectives approach to share understanding among stakeholders, thereby identifying the required and appropriate information and criteria and bringing various challenges and collaboration opportunities to benefit sustainable development. The framework allows stakeholders to understand the current situation, monitor progress, and confront challenges belonging to different domains and technological areas, indicating the need for collaborative governance (sustainable view) for ecosystems [35,39]. Meadmore et al. [45] found that, though funders of health research generally participate in similar decision-making, they focus on innovative practices that reduce bias and burden by fostering more collaboration and flexible thinking to uphold their core values.
Meanwhile, in sustainable agriculture study streams, several science and technology studies primarily focus on topics such as smart farming, big data analysis, drones, AI and robotics, IoT, and transformative agri-food supply chain systems [4,46,47]. Within policy circles, however, there is a growing demand for studies on smart agriculture that support actors and stakeholders, including farmers, advisors, policymakers, and researchers, by providing useful information, thus contributing to developing smart agriculture [4,48].
One research approach involves focusing on directions or recommendations to develop better smart agricultural policies [49,50,51,52,53,54,55]. MacRae et al. [49] proposed a framework to identify a diverse range of short-, medium-, and long-term strategies, including research, diffusion, training, market development, safety programs, and tax provisions to support the transition from conventional to sustainable agriculture. Furthermore, they recommended that the implications of widespread adoption of sustainable practices and management of the food system should be studied. Berthet et al. [50] highlighted that the transition toward sustainable agriculture requires systemic co-innovation approaches that promote central and local collaboration between researchers and stakeholders to realize technological innovation in the farming system, sectors, and value chain, enabling local solutions to contribute to larger-scale solutions. Similarly, Dale and Marshall [52] argue that policy frameworks should be developed to facilitate cooperation at the local scale among governments, the private sector, and rural communities to ensure agricultural development. Accordingly, Adamashvili et al. [54] proposed a framework to establish a successful ecosystem in the agriculture sector, which may be accomplished by a scheme where governments encourage collaborative research among key stakeholders to adopt emerging technologies. Building a digital supply chain in the agriculture sector can, for instance, accelerate a successful evolution of the ecosystem via exchanging information and knowledge among suppliers, farmers, producers, retailers, and governments [55]. Meanwhile, Noor et al. [51] emphasized the essential role of public research institutes in agriculture to provide agricultural expansion services that improve farmers’ productivity, income, and employment and generate knowledge for future sustainable growth. Thus, policies that enable public research institutes to motivate researchers with research grants, job promotions, and media publicity to grow in their careers warrants development.
The other approach focuses on investment or funding for scientific and technological research in agriculture [56,57,58,59] because, in practice, stakeholders participating in the policy process must obtain information about historical investment in the targeted research domain to discuss future funding directions. Barnes et al. [58] proposed a framework that elaborated on the research stage (e.g., basic, applied, and developmental), category (e.g., livestock and crop), and type (e.g., biological, mechanical, and chemical technologies) to determine where the public funds should be channeled appropriately. Similarly, Mogues et al. [56] argued that it is necessary to provide a framework for agriculture by analyzing information about public investments and expenditures because such information has implications for stakeholders on where to invest in agriculture. Moreover, the European Commission has emphasized the transformation of agriculture and rural areas in the EU by supporting knowledge exchange, collaboration, and research-into-practice linkages. To especially ensure more investment, collaboration programs are needed as vehicles to foster cross-sectoral linkages for knowledge exchange. Thus, it is necessary to develop an overarching and flexible policy framework to improve the situation of agriculture and rural areas where local conditions favor new research [57]. Accordingly, from survey data from project partners from six EU member states and the literature review, Stojanova et al. [59] presented seven recommendations for future smart village projects that bridge the rural-urban gap for policymakers at the local, regional, national, and EU levels. Of these recommendations, the importance of implementing specific funding schemes is stressed to communicate the attractiveness of mountainous and rural areas, thus allowing for connection and networking with stakeholders (e.g., universities and small and medium-sized establishments) and providing opportunities for new employment. However, the normative arguments must be supported via an evidence-based empirical framework.
Hence, to address the limitations of prior studies, this study proposes an information framework for public research funding in smart agriculture to identify the comprehensive investment situation, investigate the allocation of research funding from the perspective of regions and research areas, and present collaboration opportunities at the regional scale. It aims to reduce the epistemic uncertainty from the lack of knowledge of a phenomenon [30], decrease ambiguity given multiple frames (methods) about a phenomenon [30], and ensure a shared understanding of policy or strategic implications among stakeholders in decision-making [31]. Additionally, this study improves information quality through the example of strawberry, which accounts for the biggest share of smart-farming items, to facilitate the collaboration of the private sector with universities and R&D institutes at the transregional scale.

1.1.3. Research Purpose and Questions

The target research area should be divided into small areas, and the status and trends of the sub-research areas must be examined to establish a collaboration ecosystem and R&D investment framework for smart agriculture in Korea. As noted in prior studies [60,61,62], this procedure is fundamental to ensuring enhanced stakeholder collaboration by reducing information uncertainty on the knowledge status in various target fields, thereby improving the quality of decision-making on national R&D. Therefore, this study presents timely, comprehensive, and useful information on the state of R&D activities in the smart agricultural sector in 17 regions of Korea using the proposed framework. The main research questions (RQs) are as follows:
RQ1: What information is required to establish the direction of investment in the agricultural R&D sector of the Korean government that this proposed framework can provide?
RQ2: Has the Korean government’s investment trend been consistently implemented since the government announced key agricultural R&D policies, such as the announcement of the 2018 Smart Farm Expansion Plan, and does such government R&D investment implementation differ per the perspective of individual regions and various innovation-performing organizations?
RQ3: Can the proposed framework generate knowledge and strategies for various stakeholders to identify the role of the R&D cooperative ecosystem for sustainable smart farming and potential collaborators, and can it be demonstrated via the case of strawberries, a representative crop item at the forefront of smart agriculture in Korea?
Eight subcategory RQs to be examined in-depth to solve the three main RQs follows:
RQ1-1: How much has the Korean government invested in smart agriculture between 2015 and 2021?
RQ1-2: How much has the Korean government invested in smart agriculture from a regional perspective?
RQ1-3: What investment trend has the Korean government shown in the R&D areas of smart agriculture?
Beyond analyzing the direction of the Korean government’s investment in the smart agricultural industry, the following RQs were further examined:
RQ2-1: How has the Korean government’s investment trend changed since the announcement of the Smart Farm Expansion Plan, a key smart-agriculture strategy in Korea, in 2018?
RQ2-2: How does the investment status of Korean smart agriculture differ from the perspective of regions and stakeholders?
Finally, the following RQs exemplify the role and potential partners of the R&D collaborative ecosystem to share knowledge with other stakeholders by comprehensively analyzing detailed research activities for a smart-agriculture-related item (e.g., fruit):
RQ3-1: Are there regional differences in R&D collaborative ecosystems and network capabilities for a specific item (e.g., strawberry) in Korean smart agriculture?
RQ3-2: From a regional perspective, what is the difference in the competitiveness of innovative organizations (academic, industry, and research institutes) regarding, for instance, strawberries?
RQ3-3: Regarding, for instance, strawberries, which innovative organizations in the smart agricultural industry can become potential partners for strengthening the local R&D collaboration ecosystem?

2. Materials and Methods

2.1. Data Collection and Preprocessing

The study employed the national R&D portal (i.e., National Science & Technology Information Service), which provides information including programs, projects, and human resources of national R&D programs in Korea to identify smart-agriculture-related R&D projects. Titles and abstracts in the national R&D projects were translated into English. The study then extracted keywords and variants related to smart agriculture with experts from universities and research institutes to determine the search terms. Table 1 presents the dataset. Initially, 6961 nationally-funded smart-agriculture R&D projects were collected during the 2015–2021 time. Experts then thoroughly verified the relevance of smart agriculture from the collected data, bringing the data sample to 5796 projects. Finally, after removing projects with missing investment information, the final dataset comprised 5646 projects with a value of USD 1408.5 million (Table 2 and Table 3).
Further, to understand the characteristics of studies that correspond to the nationally funded research projects, this study adopted the All Science Journal Classification (ASJC) four digits of Scopus to develop the classification model that used the author keywords of approximately 1 million articles (i.e., features) and the ASJC codes assigned to each paper (i.e., labels). Thereafter, three ASJC codes and their probabilities were assigned to each nationally-funded research project calculated by the ASJC classification model [60,61,62]. The probability was determined based on the titles and abstracts of the projects. Further, a 25% threshold probability was set to identify more similar projects (clusters). Figure 3 presents a conceptual diagram of this process [60,61,62].

2.2. Clustering Process

The study identified smart-agriculture research areas via the co-occurrence matrix and investigated the relationship between ASJC codes by understanding the network structure visualized by the VOSViewer (Version 1.6.18, Leiden University, Leiden, The Netherlands) [60,61,62,63,64,65]. The number of clusters ranged from 1 (γ = 0.1) to 9 (γ = 2.0) by adjusting a resolution parameter (γ). Given the items (ASJC codes) and titles and abstracts of research projects in each cluster, eight clusters were selected.

2.3. Definition of Research Areas Related to Smart Agriculture

Smart-agriculture research areas were labeled after reviewing the content of the R&D projects and the list of the ASJC codes in each area. The labels for research areas were determined via discussions among experts in smart agriculture and relevant research areas. In the discussion, the distribution of ASJC codes comprising each cluster and titles and abstracts of the R&D projects in the clusters were provided to the experts.

2.4. Targeted Collaborative Research Area: Strawberries

Furthermore, to provide strategic implications, the study targeted strawberries as a collaborative research area. Strawberry production in Korea accounted for 10.9% (1023 million) of the total vegetable production, ranking as the largest among vegetable crops in 2021. The penetration rate of domestic strawberry varieties exceeded 96.3% relative to 9% in 2005, and the export number of strawberries reached 53.7 million dollars relative to 4.4 million dollars in 2005. From the regional perspective, Gyeongsangnam-do, Jeollanam-do, and Jeollabuk-do were ranked as the largest strawberry cultivation area [66]. The 157 projects that contained the keyword, strawberries, were reselected from the final dataset. Figure 4 presents the entire process.

3. Results

3.1. Nationally-Funded Projects Regarding Smart Agriculture

Figure 5 shows the network visualization of smart-agriculture research areas. The item or node was considered the ASJC code in the subject of study. Refer to the link of co-occurrence between the research areas of study for links indicating the relationship between the two items. The strength or weight of the link represents the number of projects in the research areas. The size of the labels and circles in each area of study was determined by the weight of the areas. Thus, the larger the weight of the research area, the larger the label and circle. The characteristics of each research area were determined by the cluster to which it belonged.
The research areas on smart agriculture were divided into eight clusters. After considering the titles and abstracts of the projects, their representative research areas, and the related keywords, the ultimate goals of each area were determined as follows:
  • Goals of Cluster 1 (Crops and Livestock): Crop Production, Growth, Livestock Growth, and Health Management Technology for Smart Agriculture. It included technologies for measuring crop growth and physiology and detecting the presence of pathogens, identifying pests and diseases.
  • Goals of Cluster 2 (Smart Energy): Renewable Energy Utilization Technology for Agricultural Power Generation for Smart Agriculture. It covered technologies to maintain and manage homeostasis in optimal conditions using minimal (renewable) energy.
  • Goals of Cluster 3 (Agri-Food and Supply Platform): Integrated Management Platform (Distribution, Logistics, and Consumption) for Digital Agriculture. It implied a platform that optimizes efficient management and marketing by sharing information about producers, consumers, and logistics companies.
  • Goals of Cluster 4 (Data·Network·AI): AI for Digital Agriculture. It contained technologies that collect real-time big data in facility horticulture or livestock and optimize environmental conditions in the AI algorithms.
  • Goals of Cluster 5 (Agricultural Machinery): Smart Agricultural Machinery and Agricultural Drone for Precision Agriculture. It included technologies that utilize agricultural machinery and robots and collect data from agricultural sites with imaging equipment and sensors mounted on unmanned aerial vehicles.
  • Goals of Cluster 6 (Farm Robots): AI Farmbots for Smart Farms. It covered technologies that can autonomously perform optimal agricultural work, as per the situation, by analyzing the status of crops and livestock.
  • Goals of Cluster 7 (Environmental Information): Complex Environmental Information Measurement and Control Technology for Smart Agriculture. It included technologies to measure external factors such as temperature, humidity, and air quality.
  • Goals of Cluster 8 (Plant Factory): Urban Agriculture Technology, including Indoor Vertical Farming System or Plant Factory for Smart Farms. It included technology to design, control, and utilize complex facilities and equipment to realize the prelude for crop and livestock production activities in a completely closed space.

3.2. Status of Government Investment in Smart Agriculture

3.2.1. Investment Status of Korean Government-Funded Projects in Smart Agriculture

Korea invested USD 674.6 million in smart agriculture from 2015 to 2021 (Table 4). Figure 6 shows the status of the government’s R&D investment in smart agriculture in 17 regions. From Table 3 and Figure 6, the regions of Seoul and Jeollabuk-do receive the most funding, accounting for 17.1% (USD 115 million) and 14.9% (USD 100 million) of government investment, respectively, followed by the Gyeonggi province (USD 8.57 million; 12.7%), Daejeon (USD 57 million; 8.5%), Jeollanam-do (USD 44 million; 6.6%), Gyeongsangnam-do (USD 39 million; 5.9%), and Chungcheongnam-do (USD 35 million; 5.3%). Information on the ratio of local investment in smart-agriculture R&D shows that the government has invested in R&D in all regions nationwide.

3.2.2. Status and Trend of Public R&D Projects by Technology Cluster of Smart Agriculture

It is important to determine the status of and comparatively analyze the investment differences in the R&D area to evaluate the R&D project portfolio adequacy. Therefore, the first step is to classify processes that can be prioritized and their projects accordingly [67]. Figure 7 shows the results of the comparative analysis of the total national R&D funds regarding technology clusters and sub-clusters in smart agriculture. First, when Korea’s smart agriculture was divided into protected agriculture (smart-farm facility), open-field agriculture (precision agriculture), and digital agriculture, the ratio of R&D investment to the amount invested was the highest for protected agriculture (61.4%). This proportion was 17.4% (21.2%) for open-field (digital) agriculture. Thus, they are in an early stage relative to protected agriculture, such as a smart farm.
Meanwhile, in protected agriculture, the largest amount of government R&D funds were invested in crop and livestock advancement (cluster [CLS] 1; 28.4%), followed by smart energy (CLS 2; 13.1%), complex environmental information advancement (CLS 7; 9.2%), farm robots (CLS 6; 6.0%), and plant factories (CLS 8; 4.8%). In digital agriculture, the funds were invested in the data·network·AI (CLS 4; 15.0%) and agri-food (CLS 3; 6.2%) platforms.
Table 4 shows the combined annual growth rate (CAGR) of smart-agriculture R&D areas from 2015 to 2021. The crop and livestock area (CLS 1) grows the fastest every year among all smart-agriculture sectors. From the perspective of R&D technology clusters, crop and livestock (CLS 1) is the fastest-growing cluster area, with investment showing 28.4% of CAGR: from USD 20.4 million in 2015 to USD 37.3 million in 2021. The second fastest-growing cluster area is open-field agriculture (CLS 5), with investment increasing from USD 6.9 million in 2015 to USD 38.9 million (CAGR: 17.4%) in 2021. For digital agriculture, the data·network·AI platform cluster (CLS 4) grew by 15.0% to USD 14.5 million in 2021, and the smart energy cluster (CLS 2) grew from USD 7.8 million in 2015 to USD 17.3 million in 2021. Thus, the government intends to strengthen R&D capabilities in related technologies such as crop and livestock advancement, open-field agriculture, digital agriculture, and smart energy.

3.2.3. Status and Trend of Government R&D Investment in Smart Agriculture from the Perspective of the Time Phase

Table 5 demonstrates how the government’s R&D investment amount and CAGR have changed since the announcement of the Smart Farm Expansion Plan in 2018. The total amount of R&D investment and the CAGR were analyzed by dividing the 2015–2021 period into Phase 1 (2015–2018) and Phase 2 (2019–2021) relative to 2018. Relative to Phase 1, the area where the CAGR increased significantly in Phase 2 was open-field agriculture (CLS 5; referred to as agricultural machinery), which grew steeply from USD 40.3 million (CAGR 27.9%) in Phase 1 to USD 76.9 million (CAGR 55.5%) in Phase 2. The area of smart energy (CLS 2) also increased in investment from USD 36.7 million (CAGR 5.6%) during Phase 1 to USD 51.4 million (CAGR 29%) during Phase 2. Moreover, the areas of crop and livestock (CLS 1; CAGR 10.6%) and environmental information (CLS 7; CAGR 15.2%) increased in investment with high growth rates in Phase 2. However, the farm robot area (CLS 2) grew at a CAGR of 101.3% in Phase 1, but in Phase 2, the growth rate of investment decreased, indicating a slowdown. Hence, R&D investment has increased in the overall technology cluster area of smart agriculture since MAFRA announced its Smart Farm Expansion Plan policy in 2018. Further, the direction of R&D investment is shifting from existing protected agriculture, such as smart farming, to open-field agriculture and energy-saving smart energy R&D from the government’s policy perspective.

3.2.4. Status and Trend of Government R&D Investment in Smart Agriculture from the Perspectives of the Region and Stakeholders

From the technology clusters and regions’ perspectives, competitiveness in regional technology was estimated by examining the status of government R&D projects. From Table 6, Korea invested in smart-agriculture research capabilities in all regions in the order of Seoul, Jeollabuk-do, Gyeonggi-do, Daejeon, Jeollanam-do, and Gyeongsangnam-do. Considering the status of R&D investment by region and R&D technology cluster, Seoul received the most investment in the areas of crop and livestock (CLS 1; USD 37.6 million), data·network·AI (CLS 4; USD 29.4 million), agricultural machinery (CLS 5, open-field agriculture; USD 11.5 million), and plant factories (CLS 8; USD 10.2 million). Jeollabuk-do, having the second-largest R&D investment, showed a similar tendency, with the most investment in crop and livestock (CLS 1; USD 29.6 million), followed by agricultural machinery (CLS 5, open-field agriculture; USD 20.6 million), data·network·AI (CLS 4; USD 16.1 million), environmental information (CLS 7; USD 8.6 million), and agri-food platform (CLS 3; USD 8.3 million). There is an even distribution of investment across the technology clusters. Jeollanam-do received the most investment in smart energy (CLS 2: USD 13.8 million) in the country, thus securing an advantage in technology competitiveness. Gyeonggi-do secured a relative advantage in environmental information technology (CLS 7; USD 7.1 million), and Gyeongsangnam-do, Gyeongsangbuk-do, and Daegu showed excellent technological competitiveness in agricultural machinery (CLS 5, open-field agriculture; USD 8.1 million, USD 8.8 million, and USD 14.3 million, respectively). Figure 8 presents a map of the investment status of the 17 regions in Korea for the eight smart-agriculture R&D technology clusters.
Regarding the status and role sharing in the industry-university-institute R&D collaboration ecosystem in the smart agricultural industry, the study reviewed the status of public R&D investment by substituting technology cluster and regional perspectives. This result shows the competitiveness of innovative organizations (industry-university-institutes) for each technology cluster of smart agriculture R&D in each region.
From Table 7, Seoul, with an edge in all technology cluster areas, including crops and livestock (CLS 1), data·network·AI (CLS 4), agricultural machinery (CLS 4), open-field agriculture (CLS 5), and plant factories (CLS 8), has balanced competitiveness (university: USD 40,817 thousand; industry: USD 37,962 thousand; institute: USD 34,232 thousand). The proportion of the industry’s R&D role in all technology cluster areas was high; thus, there is active technology development and commercialization. The result indicates the investment status by technology cluster area in each region and the competitiveness and role sharing of innovative organizations (industry-university-institute) by technology area. That is, by showing the level of industry-university-institute R&D competitiveness within the region, this result provides basic information on how to construct and support an R&D collaborative ecosystem per each region’s technological competitiveness level.

3.3. Strategic Directions of R&D Investment for Smart Agriculture from a Regional Perspective: Strawberry

This study aims to determine whether there is a regional difference in the level of the R&D collaborative ecosystem and network capabilities for specific crops. It examines the status of public R&D projects involving strawberries. Strawberries lead all aspects of Korea’s smart agriculture, such as cultivation area, production amount, and export volume, as per the Rural Development Administration and the Ministry of Agriculture, Forestry, and Food.

3.3.1. Status of Government-Funded Project Investment by Region Regarding Strawberries

The study investigates the regional R&D investment status to examine regional differences in R&D capabilities related to strawberries in Korea. The strawberry-related R&D investment is USD 11,333 thousand, and regional strawberry-related R&D capabilities were concentrated in Jeollanam-do, Gyeongsangnam-do, and Jeollabuk-do. The current proportion of R&D investment in the three regions is 67.1% of the nationwide market share. Jeollanam-do received the highest investment of USD 3095 thousand, followed by Gyeongsangnam-do (USD 2502 thousand) and Jeollabuk-do (USD 2004 thousand). Table 8 and Figure 9 show the current status of R&D investment in the 17 regions of Korea.

3.3.2. Status of Government-Funded Projects for Strawberry from the Perspectives of Technology Clusters, Stakeholders, and Regions

The study investigated the three most intensively invested regions by industry-university research subjects, technology cluster, and region to understand the R&D collaboration ecosystem and network capability level for strawberries and suggest implications for future R&D investment directions (Table 9). First, we examined the investment status of each research entity (industry-academic-research) in Jeollanam-do, Gyeongsangnam-do, and Jeollabuk-do, the top three regions with the most government R&D expenditure for strawberry production. Relative to other regions, Jeollanam-do, the region with the greatest R&D investment, saw a balanced investment in all organizations, such as companies, research institutes, and universities, and its industrial R&D capabilities are significantly greater. Gyeongsangnam-do and Jeollabuk-do saw intensive investment in research institutes, and the amount of R&D investment in their industries was small relative to the total investment amount. Thus, the amount of public R&D investment in industries is insufficient even relative to the overall status of the nation by organization. Second, the study examined the R&D investment status by technology cluster in the top three regions. Jeollanam-do saw the most investment in the areas of crop and livestock productivity advancement (CLS 1). Moreover, Jeollanam-do saw higher R&D investments in environmental information (CLS 7) and data·network·AI platform (CLS 4) than the other two regions. Meanwhile, in Gyeongsangnam-do and Jeollabuk-do, crop and livestock productivity advancement (CLS 1) saw much R&D investment.
We obtained a detailed status on innovative organization names, R&D project titles, R&D stage level, project managers, and funding size (Table 10) to present the regional R&D investment direction and potential collaboration network list of strawberry-related industries. This collaborative network list can provide information necessary for stakeholders to establish, plan, and budget adjustments to determine the nature and direction of local organization research capabilities. Furthermore, it is possible to provide useful information to make appropriate policies considering the role of each organization and the regional capabilities and realistic environments based on the organization’s strengths and weaknesses.
Jeollanam-do is an example of a practical innovation model as its R&D collaboration ecosystem is the most balanced. In a project called the Jeonnam 6th industrialization demonstration model development for strawberries based on ICT convergence, local research institutes oversaw the advanced technologies to improve new varieties for growth, quality, and productivity per the value chain of the strawberry industry. Small and medium-sized enterprises such as ELSYS and One’s Berry developed a complex environment integrated support system for optimal growth management and post-procession programs necessary for postharvest distribution and export. Universities played a role in researching growth models or standardizing related data construction and information systems. Therefore, using this collaborative model, this study can present various discussion agendas and policy implications. It enables the promotion of policies to strengthen existing networks and promotes policies to extend sustainable smart agricultural models by fostering innovative organizations with smart energy technology capabilities or technologies not included in existing network pools, such as the strawberry vertical farm factory. Moreover, in Gyeongsangnam-do and Jeollabuk-do, where R&D capabilities are relatively concentrated in research institutes, policies can be proposed to support technology commercialization promotion programs, such as venture company start-ups and technology transfers.
The study investigated recent research trends of government-funded R&D projects to provide potential R&D collaboration partners in the strawberry-related industry. Table 11 lists recent R&D projects related to strawberry pest control technology. Innovative organizations with technological competitiveness in controlling strawberry-related pests include Chungcheongnam-do Agricultural Technology Institute in Chungcheongnam-do, National Horticultural Research Institute, and Chonbuk National University in Jeollabuk-do. This list can provide information as a tool to find potential collaboration partners for innovative models of R&D collaboration, such as in Jeollanam-do. That is, it is possible to strengthen the R&D innovation model of local smart agriculture by establishing a new cooperation system with innovative organizations that have pest control technologies in other regions not included in the existing R&D collaboration network pool.

4. Discussion

4.1. R&D Investment Strategy and Collaborative Ecosystem Framework for Sustainable Smart Agriculture in Korea

The proposed framework for sustainable smart agriculture in Korea provides a variety of useful information regarding research areas, regions, and stakeholders. Three RQs (eight subcategory RQs) were raised to demonstrate the usability of the framework. First, regarding RQ1, the study provided useful information to establish the investment direction of the Korean government in the agricultural R&D sector. Specifically, regarding RQ1-1 and RQ1-2, the study revealed the overall and regional status of government R&D investment in smart agriculture during the 2015–2021 period to provide evidence to stakeholders to discuss the appropriateness of R&D investment from the Korean central and local government perspective. Regarding RQ1-3, the study examined the investment situation of government R&D from the perspective of research areas on smart agriculture in Korea to provide information to determine the concentration of research areas, thereby discussing the degree of government R&D investment in each research area.
Second, regarding RQ2, we investigated changes in the government R&D investment trend as of 2018 when the Smart Farm Expansion Plan was announced. Moreover, the implementation of such government R&D investment was analyzed for differences per individual regions and innovative organizations performing R&D. The emergent result showed that the total amount of government R&D investment increased significantly, and the direction of the investment shifted from protected agriculture, such as smart farming, to open-field agriculture. Further, the government focused on smart energy R&D while considering the global environmental issue of carbon neutrality. Thus, stakeholders can use this information to discuss the allocation of government R&D investment for the next national smart agriculture plan. Regarding RQ2-2, the study investigated the status of public R&D investment concerning technology clusters, regions, and organizations. The results showed the degree of R&D capabilities of the industry-university-institutes in the regions and the regional research competitiveness, which can be the starting point to build and support an R&D collaboration ecosystem for a research area. Moreover, for central and local policymakers in charge of developing collaboration programs, these results can be adopted as fundamental information to enhance a strategic R&D collaboration or partnership in a specific research domain.
Third, regarding RQ3, the proposed framework presents the information needed to establish knowledge and strategies for various stakeholders to discover the role of the R&D cooperation ecosystem for sustainable smart farming and potential collaborators. Furthermore, we demonstrated the usefulness of the framework in creating an R&D collaboration ecosystem through the strawberry case. Regarding RQ3-1, the study identified the three regions with the highest R&D investment. This result showed the potentially attractive or benchmarking regions to be investigated. Regarding RQ3-2 and RQ3-3, we examined the level of the R&D collaborative ecosystem and network capabilities for strawberries and suggested future collaboration strategies for government R&D investment. The study provided detailed information, such as organization name, R&D project title, R&D stage level, project manager, and fund size, to present the direction of regional R&D investment and the potential collaboration network list for strawberry-related industries. The collaboration situation and potential network lists may become essential information to ensure coordination, planning, and budget adjustments to determine the nature and direction of R&D in local research organizations. Moreover, it is possible to provide useful information to develop appropriate policies considering the role of each organization, its regional capabilities, and the realistic environment per its strengths and weaknesses.

4.2. Conclusions

The Korean government has continuously announced national plans regarding smart agriculture, including the 2nd Comprehensive Plan (2014) [12], Smart Farm Expansion Plan (2018) [15], 3rd Comprehensive Plan (2019) [13], Smart Farm Innovation Valley projects in four regions (2018–2019) [27], and comprehensive measures to extend smart agriculture based on big data and AI (2021) [16]. Such announcements of national policies on smart agriculture may indicate a lack of a coherent plan, thereby deteriorating the effect of government investment [28] (National Assembly Legislative Research Office, 2019). Thus, there is a need to examine the status of smart agriculture from the perspective of technology and local innovative organizations to narrow the urban-rural gap by developing a practical framework that allows for showing the comprehensive investment situation, identifying the allocation of research funding from the perspective of regions and research areas, and bringing collaboration opportunities at the regional scale.
The proposed framework, stemming from previous works, showed changes in the Korean smart agriculture R&D policy that induced big data and AI-based digital agriculture extended the policy to open-field precision agriculture, and promoted urban factories in protected agriculture, which was previously largely confined to rural areas. That is, the policies have shifted from automation to intelligent automation and rural agriculture to urban agriculture. Furthermore, the case study of strawberry production empirically demonstrated the usability of creating a collaborative research ecosystem at the transregional scale.
This study makes two important contributions. First, it suggested the framework for government R&D investment and collaboration in the smart-agriculture sector. Multiple prior studies [49,50,51,52,53] provided directions or recommendations to develop better smart agricultural policies without considering government R&D investment information. However, it may create a bias in stakeholders during decision-making [45], thereby increasing ambiguity and the number of differing perspectives held by stakeholders [30,31]. This study addressed the limitation in the literature [49,50,51,52,53] by discussing the fundamental functions of a robust framework that enables stakeholders to understand the research investment situation, monitor research investment progress, and identify challenges in different technological areas and regions that need collaboration to ensure sustainability [35,39]. Thus, policymakers and stakeholders of central and local governments can view the investment concentration and regional distribution and set directions to consider the appropriate government investment to enhance regional competitiveness and capabilities.
Second, the study empirically showed how to operate the framework for smart agriculture. Although some previous studies on agriculture policy proposed practical investment frameworks [56,58], their frameworks did not show the systematic analysis process, including a precisely integrated innovation scheme with regional, technical, and organizational dimensions. However, this study provided information on the current situation of government R&D investment and showed various stakeholders (e.g., universities and research institutions) in smart agriculture from the perspective of 17 regions and technology clusters during the 2015–2021 period. Moreover, few prior studies [54,57,59] emphasize the importance of collaboration programs to support research-into-practice linkages in rural areas to accomplish an agricultural transformation. In response to these requests, this study considered the case of a research collaboration ecosystem for strawberries. In this study, the Jeollanam-do region was introduced as having developed the most balanced R&D collaboration ecosystem, and the list and status of potential future collaboration partnerships in this region were presented. Insights from this collaboration case study can help central and local governments develop policies to reinforce sustainable smart-farming models by nurturing innovative organizations with smart energy or strawberry pest control technology that are excluded from the existing network pool. Furthermore, local governments in Gyeongsangnam-do and Jeollabuk-do, where research institutions are relatively concentrated, must develop policies to support technology commercialization promotion programs, such as venture business start-ups and technology transfer, to address the weaknesses of the current research institute-oriented ecosystem.

4.3. Limitations and Further Research

Despite these contributions, this study has some limitations that present challenging questions for future research [60]. The data on public R&D projects were taken from the central government because there was no database on the R&D expenditures of the 17 local governments. Thus, the dataset for local government-funded projects must be assessed. Moreover, this study examined limited information items. Hence, future studies can examine more information (e.g., comparison of ministries’ budgets) required by stakeholders (central and local government, research funding agencies, universities, private sectors, and research institutes). Meanwhile, to ensure the legitimacy of policy decision-making, future studies must develop a fair procedure that can reduce conflicts between stakeholders. Thus, for decision-makers, future studies can conduct a qualitative analysis of the degree of fairness in the information production procedure of the proposed framework and whether the information included multiple perspectives and greater transparency and investigated how the legitimacy is affected by participants’ perspectives in an extended consideration.
