Drivers, barriers and impacts of digitalisation in rural areas from the viewpoint of experts
Ferrari A., Bacco M., Gaber K., Jedlitschka A., Hess S., Kaipainen J., Koltsida P., Toli E., Brunori G.
[Context] The domain of rural areas, including rural communities, agriculture, and forestry, is going through a process of deep digital transformation. Digitalisation can have positive impacts on sustainability in terms of greater environmental control, and community prosperity. At the same time, it can also have disruptive effects, with the marginalisation of actors that cannot cope with the change. When developing a novel system for rural areas, requirements engineers should carefully consider the specific socio-economic characteristics of the domain, so that potential positive effects can be maximised, while mitigating negative impacts. [Objective] The goal of this paper is to support requirements engineers with a reference catalogue of drivers, barriers and potential impacts associated to the introduction of novel ICT solutions in rural areas. [Method] To this end, we interview 30 cross-disciplinary experts in digitalisation of rural areas, and we analyse the transcripts to identify common themes. [Results] According to the experts, main drivers are economic, with the possibility of reducing costs, and regulatory, as institutions push for more precise tracing and monitoring of production; barriers are the limited connectivity, but also distrust towards technology and other socio-cultural aspects; positive impacts are socio-economic (e.g., reduction of manual labor, greater productivity), while negative ones include potential dependency from technology, with loss of hands-on expertise, and marginalisation of certain actors (e.g., small farms, subjects with limited education). [Conclusion] This paper contributes to the literature with a domain-specific catalogue that characterises digitalisation in rural areas. The catalogue can be used as a reference baseline for requirements elicitation endeavours in rural areas, to support domain analysis prior to the development of novel solutions, as well as fit-gap analysis for the adaptation of existing technologies.Source: Information and software technology 145 (2022). doi:10.1016/j.infsof.2021.106816

Technology, digitalisation, and AI for sustainability. An assessment of digitalisation for food system transitions
Brunori G., Bacco M., Rolandi S.
This chapter discusses one of the most urgent and significant challenges we must face-- the transition towards sustainable food systems. In this context, we discuss the role digital technologies may play, proposing the use of socio-cyber-physical systems as a paradigm, and extension of its Information and Communications Technology version, the cyber-physical system. Key digital technologies, with the potential of being game changers, are identified, as is their role in supporting a transition towards greater sustainability. Risks are identified and discussed related to the adoption of digital technologies in the food system, as well as policy conditions for digital technologies to operate in societies' interest. Recommendations are provided on the embodiment of socio-economic principles in the digitalisation process, in line with the socio-cyber-physical approach.Project(s): DESIRA via OpenAIRE

A path-aware scheduler for Air-to-ground multipath multimedia delivery in real time
Machumilane A., Gotta A., Cassarà P., Bacco M.
The use of multipath techniques in transmission has emerged in the last years thanks to their potential in increasing throughput. They can also be used as a means to counteract errors or losses in transmission, thus increasing reliability. In this work, we focus on the challenging scenario of real-time video streaming from an Unmanned Aerial Vehicle (UAV) via multiple wireless channels. We propose a lightweight scheduler capable of dynamically selecting the paths to be used and of determining the necessary redundancy rate to protect the multimedia flow. Our scheduler, implemented as a module of the GStreamer framework, can be used in real or simulated settings. The results we present show that the proposed scheduler can be used to target a very low loss rate by dynamically adapt to varying channel conditions in terms of losses and experienced delay.Source: IEEE communications magazine (Online) (2022). doi:10.1109/MCOM.001.2100904

Crop diversification in South Asia: a panel regression approach
Singh P., Adhale P., Guleria A., Bhoi P. B., Bhoi A. K., Bacco M., Barsocchi P.
South Asia's agricultural sector has experienced vigorous growth and structural transformation over the last few decades, albeit differently across the region. This study examines the crop diversification status and various determinants such as socioeconomic (per capita gross domestic product, population, arable land, and cropland), soil/agronomic (root zone moisture), agricultural inputs (fertilizer and pesticide consumption), the productivity of food and non-food crops, international trade, and climate (maximum and minimum temperature and rainfall) factors. The share of cereals has decreased in most countries, but they continue to dominate South Asian agriculture. The area under high-value crops in India has increased significantly, replaced the area under cereal cultivation during the study period. Similar results were seen in the Maldives, where vegetables replaced oilseeds. The Hausman model test suggested a random-effects model for the analysis of the determinants. All the determinants considered in the study explain 69 percent of the variation in the crop diversification index. The crop diversification in south Asia was influenced by per capita GDP, minimum temperature, pesticide consumption, food crop yield index, and non-food crop yield index during the study period. Cropland percentage and population, on the other hand, reduce the crop diversification. The price factor contributed more than half to agricultural growth. It remained the primary source of growth in all South Asian countries, followed by yield, which is identified as the second most crucial factor. The contribution of crop diversification to agricultural growth has been declining over time.Source: Sustainability (Basel) 14 (2022). doi:10.3390/su14159363

Unmanned Aerial Vehicles for Agriculture: an overview of IoT-based scenarios
Bacco M., Barsocchi P., Gotta A., Ruggeri M.
The agricultural sector is experiencing a new revolution, giving birth to the so-called Agriculture 4.0 paradigm. It brings digital technologies in the field to support the farmers' work, enhancing the productivity of farms. In this chapter, the attention is focused on the role that both Internet of Things (IoT) and Unmanned Aerial Vehicles (UAVs) can play in this regard, whether used in a joint manner or not. We analyse the work being done both in recent research projects and in the literature on those topics, taking into account the role of long-range wireless communications to enable such scenarios, and the potential of 5G and the upcoming Multi-Access Edge Computing (MEC) technology, especially in rural areas, where the lack of connectivity is still hampering the process of digital transformation.Source: Autonomous Airborne Wireless Networks, edited by Muhammad Ali Imran, Oluwakayode Onireti, Shuja Ansari, Qammer H.

The digitalization of agriculture and rural areas: towards a taxonomy of the impacts
Rolandi S., Brunori G., Bacco M., Scotti I.
The literature about digitalization in agriculture and rural areas is vast and sectorial at the same time. Both international political institutions and practitioners are interested in promoting digital technology, indicating and describing potential benefits and risks. Meanwhile, academics analyse the actual and possible impacts of digital technologies using case studies. However, the extensive literature makes it challenging to derive a comprehensive synthesis of the possible impacts that digital technologies are and might generate in the rural domains. In the given context, the present work aims at contributing to the construction of a framework providing a first classification of the digital technologies impacts to use in both research and political agenda.Source: Sustainability (Basel) 13 (2021): 1–19. doi:10.3390/su13095172

Smart and sustainable food: what is ahead
Bacco M., Brunori G., Rolandi S., Scotti I.
Food systems are evolving to support sustainable food security. In this chapter, we aim at discussing the role that digital technologies play, especially those with the potential to provoke deep changes. The ongoing revolution in this field has given birth to the so-called Agrifood 4.0. Our interest lies also on the impact of digital technologies in the food chain, from production to consumption, especially the case of food loss and waste. In fact, the growing use of ICT in this field may generate game-changing effects, which can be positive or negative, affecting productivity, sustainability, and other aspects. We consider both present and future scenarios, looking at the potential of novel techniques - as for instance 3D printing of food, use of blockchain, and smart packaging - taking into account the sustainability criteria proposed by the Agenda 2030 of the UN to assess the changes on tasks and procedures all along the food chain.Source: Future Foods.

Digital transformation of agriculture and rural areas: a Socio-Cyber-Physical System framework to support responsibilisation
Rijswijk K., Klerkx L., Bacco M., Bartolini F., Bulten E., Debruyne L., Dessein J., Scotti I., Brunori G.
Digital technologies are often seen as an opportunity to enable sustainable futures in agriculture and rural areas. However, this digital transformation process is not inherently good as it impacts on many aspects (e.g. economic, environmental, social, technological, institutional) and their relations. The Responsible Research and Innovation approach calls for a better understanding and anticipation of the often unknown impacts. To meet this aim we have developed a framework that allows to gain insight on the relations between the social, the cyber and the physical, i.e. a Socio-Cyber-Physical System and have described conditions for a successful digital transformation of such a system. These are design of, and creating access to digital technologies, and navigating system complexity. This framework allows for a better problematisation of digital transformation and has been illustrated through an example of digital dairy farming. It supports an enhanced understanding of moral responsibilities regarding digital transformation, fitting within the Responsible Research and Innovation approach, as well as the succinct step of understanding who is responsible or accountable for the identified (positive or negative) impacts, i.e. responsibilisation.Source: Journal of rural studies 85 (2021): 79–90. doi:10.1016/j.jrurstud.2021.05.003

This paper discusses the perspective of the H2020 TEACHING project on the next generation of autonomous applications running in a distributed and highly heterogeneous environment comprising both virtual and physical resources spanning the edge-cloud continuum. TEACHING puts forward a human-centred vision leveraging the physiological, emotional, and cognitive state of the users as a driver for the adaptation and optimization of the autonomous applications. It does so by building a distributed, embedded and federated learning system complemented by methods and tools to enforce its dependability, security and privacy preservation. The paper discusses the main concepts of the TEACHING approach and singles out the main AI-related research challenges associated with it. Further, we provide a discussion of the design choices for the TEACHING system to tackle the aforementioned challenges.Source: IEEE COINS 2021 - IEEE International Conference on Omni-layer Intelligent systems, Online conference, 23-26/08/2021

Input use efficiency management for Paddy Production Systems in India: a machine learning approach
Bhoi P. B., Wali V. S., Swain D. K., Sharma K., Bhoi A. K., Bacco M., Barsocchi P.
This research illustrates the technical efficiency of the pan-India paddy cultivation status obtained through a stochastic frontier approach. The results suggest that the mean technical efficiency varies from 0.64 in Gujarat to 0.95 in Odisha. Inputs like human labor, mechanical labor, fertilizer, irrigation and insecticide were found to determine the yield in paddy cultivation across India (except for Chhattisgarh). Inefficiency in the paddy production in Punjab, Bihar, West Bengal, Andhra Pradesh, Tamil Nadu, Kerala, Assam, Gujarat and Odisha in 2016-2017 was caused by technical inefficiency due to poor input management, as suggested by the significant ?2U and ?2v values of the stochastic frontier model. In addition, most of the farm groups in the study operated in the high-efficiency group (80-90% technical efficiency). No specific pattern of input use can be visualized through descriptive measures to give any specific policy implication. Thus, machine learning algorithms based on the input parameters were tested on the data in order to predict the farmers' efficiency class for individual states. The highest mean accuracy of 0.80 for the models of all of the states was achieved in random forest models. Among the various states of India, the best random forest prediction model based on accuracy was fitted to the input data of Bihar (0.91), followed by Uttar Pradesh (0.89), Andhra Pradesh (0.88), Assam (0.88) and West Bengal (0.86). Thus, the study provides a technique for the classification and prediction of a farmer's efficiency group from the levels of input use in paddy cultivation for each state in the study. The study uses the DES input dataset to classify and predict the efficiency group of the farmer, as other machine learning models in agriculture have used mostly satellite, spectral imaging and soil property data to detect disease, weeds and crops.Source: Agriculture (Basel) 11 (2021). doi:10.3390/agriculture11090837

Air-to-ground real-time multimedia delivery: a multipath testbed
Bacco M., Cassarà P., Gotta A.
In this work, we focus our attention on real-time multimedia flows from Unmanned Aerial Vehicles (UAVs) to the ground, presenting and analysing the data collected in field trials during a real testbed. The objective is assessing whether a video feed of reasonable quality can be provided to the pilot of a UAV to enable Beyond Visual Line of Sight (BVLoS) operations, by exploiting the multiple cellular operators available in the area. Three cellular networks have been jointly used in a multihoming/multipath setup, leveraging the variable coverage offered in both urban and suburban environments. Taking into account both Quality of Service (QoS) and Quality of Experience (QoE) metrics, the target parameters measured in this testbed are: latency, packet error rate, and video quality, which accounts for frames integrity, continuity, and fluidity. Data collected on the field allow evaluating both QoS and QoE in the presence of a multipath architecture, showing how the latter, in the presence of network diversity, offer the possibility to improve the QoE at the receiver. We also design a framework to characterize the error model and to map it into a QoE model, therefore providing an analytical characterisation of a multipath channel.Source: Vehicular communications (Print) 33 (2021). doi:10.1016/j.vehcom.2021.100443

Using NLP to support terminology extraction and domain scoping: report on the H2020 DESIRA project
Bacco F. M., Brunori G., Dell'Orletta F., Ferrari A.
The ongoing phenomenon of digitisation is changing social and work life, with tangible effects on the socio-economic context. Understanding the impact, opportunities, and threats of digital transformation requires the identication of viewpoints from a large diversity of stakeholders, from policy makers to domain experts, and from engineers to common citizens. The DESIRA (Digitisation: Economic and Social Impacts in Rural Areas) EU H2020 project1 considers rural areas, with a strong focus on agricultural and forestry activities, and aims at assessing the impact of digital technologies in those domains by involving a large number of stakeholders, all across Europe, around 20 focal questions. Given the involvement of stakeholders with diverse background and skills, a primary goal of the project is to develop domain-specic and interactive reference taxonomies (i.e., structured classications of terms) to facilitate common understanding of technologies in use in each domain at today. The taxonomies, which aims at easing the learning of the meaning of technical and domain-specic terms, are going to be exploited by the stakeholders in 20 Living Labs built around the focal questions. This report paper focuses on the semi-automatic development of the taxonomies through natural language processing (NLP) techniques based on context-specic term extraction. Furthermore, we crawl Wikipedia to enrich the taxonomies with additional categories and denitions. We plan to validate the taxonomies through fieeld studies within the Living Labs.Source: Third Workshop on Natural Language Processing for Requirements Engineering, pp. 1–5, Pisa, Italy, 24 March 2020

Monitoring ancient buildings: real deployment of an IoT system enhanced by UAVs and virtual reality
Bacco M., Barsocchi P., Cassarà P., Germanese D., Gotta A., Leone G. R., Moroni D., Pascali M. A., Tampucci M.
The historical buildings of a nation are the tangible signs of its history and culture. Their preservation deserves considerable attention, being of primary importance from a historical, cultural, and economic point of view. Having a scalable and reliable monitoring system plays an important role in the Structural Health Monitoring (SHM): therefore, this paper proposes an Internet Of Things (IoT) architecture for a remote monitoring system that is able to integrate, through the Virtual Reality (VR) paradigm, the environmental and mechanical data acquired by a wireless sensor network set on three ancient buildings with the images and context information acquired by an Unmanned Aerial Vehicle (UAV). Moreover, the information provided by the UAV allows to promptly inspect the critical structural damage, such as the patterns of cracks in the structural components of the building being monitored. Our approach opens new scenarios to support SHM activities, because an operator can interact with real-time data retrieved from a Wireless Sensor Network (WSN) by means of the VR environment.Source: IEEE access (2020). doi:10.1109/ACCESS.2020.2980359

Simulatore per trasmissioni multimediali Real-Time da drone a terra
Puddu M.
L'obiettivo di questo tirocinio è l'implementazione di un emulatore che riproduce la trasmissione di un video da un drone a terra. Il drone dispone di una videocamera. Al fine di rendere più robusta la comunicazione e avere maggiore disponibilità di banda, l'emulatore permette di creare un canale aggregato che sfrutta più canali fisici reali. A tale scopo un modulo di scheduling viene utilizzato per decidere quali e quanti canali utilizzare sulla base delle statistiche di ciascun canale fisico. Inoltre, per rendere la comunicazione anche più robusta, è prevista la possibilità di trasmettere il flusso multimediale su più canali contemporaneamente (in modo duplicato o non), così da aumentare la probabilità di una corretta ricezione a destinazione. Il modulo di scheduling dovrà utilizzare i canali in modo intelligente, ovvero sfruttare meno canali e meno repliche possibili, mantendo la migliore qualità video. A tale scopo un modulo definito di scheduling controller ha il compito di monitorare lo stato dei canali in termini di ritardo, jitter e tasso di perdita dei pacchetti, così da aggiornare attraverso una funzione di ottimizzazione i pesi dello scheduler. Il ricevitore si deve occupare di ordinare ed eventualmente scartare ricezioni multiple dovute alle repliche inviate sui canali.

Analisi e Visualizzazione di Categorie Wikipedia Tramite Grafi
Fenu G. M.
Contesto Negli ultimi anni, le tecniche di sviluppo del software si sono evolute di pari passo con la crescita delle dimensioni e della complessità dei programmi. L'aumentare della complessità dei programmi ha reso necessario la definizione di modelli di sviluppo per il software, dalla sua concezione iniziale, fino alla sua completa realizzazione. Un generico modello di sviluppo software include le nozioni di specifica delle funzionalità del software, di design e di architettura software. La specifica delle funzionalità del software si concentra sulla definizione di requisiti del sistema, cioè bisogni e obiettivi che il sistema deve soddisfare. La necessità di definire bisogni e obiettivi, che rappresentino al meglio un sistema software, ha fatto nascere nuove aree di studio come l'Ingegneria dei Requisiti, e nuove figure professionali come l'analista di requisiti (noto anche come analista funzionale), che si occupa di identificare, raccogliere, documentare e analizzare i requisiti. Problema Durante il processo di raccolta dei requisiti vengono coinvolti anche domini diversi allo stesso momento, e gli analisti devono interagire con gli esperti del dominio per ottenere le conoscenze del dominio necessarie per sviluppare il sistema. A tal fine, vengono organizzati incontri con i soggetti interessati sotto forma di interviste, focus group o workshop. Durante queste riunioni, gli analisti dei requisiti e gli esperti di dominio potrebbero usare i loro gerghi specializzati e potrebbero sorgere ambiguità tra analisti ed esperti di dominio, nonché tra parti interessate appartenenti a domini diversi. L'ambiguità nella comunicazione è considerata un grave ostacolo per il trasferimento di conoscenze, dal momento che bisogni o aspetti del dominio comunicati in modo non corretto potrebbero portare alla definizione di requisiti scadenti, che possono causare problemi nelle fasi successive dello sviluppo. Soluzione Questa tesi propone di aiutare gli analisti dei requisiti e gli esperti di dominio nel creare uno spazio comune di conoscenza per facilitare la comunicazione durante le fasi di raccolta dei requisiti. Questo obiettivo viene raggiunto tramite la definizione di una tassonomia interattiva di termini tecnici, navigabile e collegata a Wikipedia. La tassonomia può essere visualizzata da esperti di dominio e analisti dei requisiti per esplorare i rispettivi ambiti terminologici. A tal fine, nel contesto di questa tesi è stato sviluppato il tool \textbf{WikiScan}, che permette di scaricare automaticamente categorie e pagine Wikipedia specifiche di uno o più domini, e di rappresentare le relazioni tra le pagine tramite un grafo visuale navigabile. Contributo WikiScan può aiutare gli utenti a esplorare attivamente i nuovi domini, partendo da termini noti ed espandendo le proprie conoscenze. Data una categoria di interesse, WikiScan permette di esplorare tutte le sotto-categorie e pagine Wikipedia, al fine di creare un indice navigabile ed evidenziare elementi comuni fra domini di partenza diversi, nonché di accedere a Wikipedia stessa per approfondimenti. Lo sviluppo del tool WikiScan fa parte del lavoro di tirocinio svolto all'interno dell'Istituto di Scienza e Tecnologie dell'Informazione (ISTI) del CNR, sede di Pisa.

A simulation framework for QoE-Aware real-time video streaming in multipath scenarios
Bacco M., Cassarà P., Gotta A., Puddu M.
This work presents the ongoing development of a simulation/emulation framework for real-time multimedia transmissions in multichannel scenarios. The proposed software engine can be used to simulate the aggregation of multiple network links delivering a video flow from a video source, such as a camera mounted on-board an Unmanned Aerial Vehicle (UAV), to the indented receiver, such as the pilot on the ground. The software engine can also be used in real testbeds exploiting multiple physical links, such as 4G/5G cellular connections. The main aim of this novel software framework is to support the design, development, and test of different scheduling strategies to achieve real-time, good quality and fluidity, energy-efficient multimedia transmissions, by selecting the optimal subset of network channels able to meet the target Quality of Experience (QoE) at the receiver.Source: AdHoc-Now 2020 - The 19th International Conference on Ad Hoc Networks and Wireless, pp. 114–121, Bari, Italy, 19-21 October 2020
