• Digitalisation of the agrifood sector: what does Twitter tell us?


    Technology is advancing at a frenetic pace and offers the agrifood chain a large number of opportunities to make its production more efficient and sustainable. Moreover, the arrival of COVID-19 has shown that the most digitalised companies were able to continue their activities more readily than the rest. In this article we examine the degree of popularity of the different digital technologies used in the primary sector and agrifood industry based on a text analysis of over 2 million tweets on Twitter. All these technologies are essential to create a connected ecosystem that will make up the Food Chain 4.0 of the future.

    The unexpected arrival of the pandemic has shown that the most digitalised companies were more prepared to adapt to the new situation and were able to continue to operate much more smoothly than the rest. There is no doubt that, in this new environment, the digital transformation of companies is now unavoidable in order to boost their competitiveness.

    Big data, robotics, the internet of things and blockchain are just some examples of the new digital technologies gradually being adapted by firms, particularly in the agrifood sector. Technology is advancing at a frenetic pace and is offering the agrifood chain a large number of opportunities to produce more efficiently and sustainably. However, statistical information on the degree to which such technologies have been taken up, and the most comprehensive official statistical source1, does not provide information on the primary sector. Below we present a novel analysis of the «popularity»  of new digital technologies in the agrifood sector based on data from Twitter.

    Twitter as a source of information to detect future trends

    Data from Twitter can be extremely valuable in detecting new trends as it allows us to analyse the popularity of certain terms according to how frequently they appear in tweets. However, it is true that «talking about something» is not the same as successfully implementing the various digital technologies in a company's recurring operations. For this reason the results presented below should be interpreted simply as an indication of new trends that may be taking root in agrifood companies.

    Data from Twitter allow us to analyse how popular the different digital technologies

    are in the agrifood sector according to how often they are mentioned in tweets.

    For this study, data was processed from over 24 million tweets sent by individual users and digital media during the period 2017-2019. Among these, 2 million corresponded to the agrifood sector. Using natural language processing techniques, the tweets were categorised according to mentions of different digital technologies and to the business sector.2 The key to obtaining relevant data from social media is to first define «seed» words or phrases to identify texts corresponding to each of the business sectors, as well as «seed» words or phrases related to the different digital technologies of interest.3 Using a machine-learning algorithm, other words and phrases related to the concept in question that were not initially included were also identified, thus broadening the spectrum of texts analysed. At this stage, it is important to carefully screen for polysemous words (i.e. those that have more than one meaning, such as the word «reserva» in Spanish, which can be used to refer to a hotel booking as well as an aged wine).

    • 2. This analysis was carried out in collaboration with Citibeats, a company specialising in unstructured natural language processing.
    • 3. For example, the «seed» woods and phrases used to identify big data were: analytics, arquitectura de sistemas (system architecture), data mining, database, inteligencia empresarial (business intelligence), Python and SQL, among others (as well as the term big data per se).
    What is the degree of digitalisation of the agrifood sector according to Twitter?

    To assess the agrifood sector's degree of digitalisation according to data from Twitter, we first need to know how common tweets about digitalisation are in other business sectors. The most digitalised industry according to our analysis is the information and communication technologies (ICT) sector: 3.2% of the sector's tweets contain terms related to digitalisation, a result that is not surprising given the very nature of the industry. Next comes finance and insurance with 2.7% of the tweets.

    This percentage is obviously lower in the primary sector at 0.6% but it is similar to the 0.7% for professional, scientific and technical activities. In the case of the agrifood industry, the percentage of tweets on digitalisation is only 0.3%, very close to the basic manufacturing sector (which includes the textile, wood, paper and graphic arts industries), with the lowest percentage among the sectors analysed, 0.2%.

    Which digital technologies are most popular in the agrifood sector according to Twitter?

    The wealth of data obtained from Twitter allow us to identify the most popular digital tools in each business sector according to how frequently they are mentioned in the tweets examined. According to our analysis, a large proportion of the primary sector's tweets about digitalisation tend to include issues related to big data (45% of all tweets about digitalisation). One clear example of the application of big data in the sector can be found in «precision agriculture» techniques which require large amounts of data to be analysed to optimise decisions and thereby increase production and, in turn, ensure sustainability. These techniques are used, for instance, to calculate the irrigation requirements of crops by taking into account climatic conditions (sunlight, wind, temperature and relative humidity) and crop characteristics (species, state of development, planting density, etc.). To carry out this calculation, real-time updated meteorological data, a large computing capacity and fast data transmission speeds are all required for an automatic irrigation system to be properly adjusted. This technology helps to use water more efficiently, a highly relevant aspect in areas with a Mediterranean climate that are extremely vulnerable to climate change and where water is in short supply.

    Big data, the internet of things and robotics are the most popular technologies in the primary sector,

    indispensable for advancing the application of precision agriculture techniques and smart automated farming.

    Other popular technologies in the primary sector are the internet of things (16% of tweets) and robotics, including drones (10% of tweets). The new digital technologies promise to revolutionise the field of agriculture and stockbreeding by the middle of this century, the same as the mechanisation of farming in the xxi century. Agricultural Machinery 4.0 (which is closer to the robots in science fiction films than to the tractors we are used to seeing on all farms in the country) helps to increase productivity whilst also improving working conditions in the field. This trend towards more automated agricultural tasks has become stronger in the wake of the coronavirus pandemic, as the difficulty in recruiting seasonal workers due to international mobility restrictions has led to increased interest in robotics and agricultural automation. In fact, companies that manufacture robots for agriculture have seen a sharp increase in orders, such as robots that pick strawberries while removing mould with ultraviolet light.14 

    The use of drones warrants particular attention as this has grown exponentially in recent years and applications are increasingly widespread: from the early detection of pests and the aerial inspection of large areas of crops to locating wild boar with heat-sensitive cameras to prevent the spread of African swine fever to domestic pigs.5

    The popularity of various digital technologies in the agrifood sector

    p 28

    Blockchain is the technology that stands out most in the food sector (30% of the total number of tweets on the sector's digitalisation) and this comes as no surprise as it has many different applications for the food and beverage industry. Producing a chain of unalterable, reliable records, blockchain makes it possible to guarantee the complete traceability of products throughout all the links in the food chain. Simply scanning a QR code provides access to all the data regarding the origin, production method, veterinary treatments received, ingredients used, etc. A large number of agrifood companies are already experimenting with blockchain as it offers clear benefits in terms of transparency regarding origin, product quality and food safety, aspects that are increasingly valued by consumers. Blockchain technology is also being used to limit food waste, another essential challenge for the sector.

    Blockchain enables the digital verification of food products,

    making them traceable throughout the links in the food chain.

    Compared with other sectors, which tools are particularly significant for the agrifood industry?

    There are some digital technologies that are not very popular across all economic sectors, perhaps because they have a more limited or specific range of application. These are technologies that, despite having a low percentage of tweets in absolute terms according to our study, may be relatively popular for a particular sector compared with the rest.

    To detect such cases, we have calculated a new metric, namely a concentration index which takes into account the relative popularity of technologies in a sector compared with the rest of the sectors.6 By using this methodology, we have found that the primary sector continues to stand out in terms of big data. Specifically, the primary sector concentrates 9.2% of the total number of tweets mentioning big data made by all sectors, a much larger proportion than the 3.1% share of primary sector tweets out of the total number of tweets analysed (as can be seen in the following table, in this case the concentration index is 3). We have also determined that the sector is particularly interested in the internet of things, as already mentioned, but have discovered that nanotechnology is also a relatively popular technology in the primary sector. In other words, although only 3.8% of the tweets in the primary sector deal with nanotechnology, this percentage is high compared with the 1.7% share of nanotechnology tweets out of the total (in other words, this technology is not very popular in general across all sectors but is slightly more popular in the primary sector than the others). This find is not surprising since genetic engineering is one of the fields in which technology has advanced most in order to boost crop yields. For example, by optimising the yield of vines it is possible to develop plants that are much more resistant to extreme weather conditions and pests.

    • 6. The concentration index is calculated as the ratio between (1) the percentage of tweets related to a particular technology and sector out of the total tweets for this technology, and (2) the percentage of tweets by a sector out of the total tweets of all sectors. Values above 1 indicate the technology is relatively more popular in that sector.

    Concentration index for tweets related to each technology in comparison with the other sectors

    p 29

    Finally, virtual and augmented reality is also a relatively popular technology in
    the agrifood industry.
    Specifically, the agrifood industry concentrates 6.2% of the total virtual and augmented reality tweets made by all sectors, a percentage that more than doubles the 2.5% share of primary sector tweets out of the total number of tweets analysed (the concentration index is equal to 2.5 in this case). This technology uses virtual environments (virtual reality) or incorporates virtual elements into reality (augmented reality) that provide additional knowledge and data that can be used to optimise processes. At first it may be surprising that this technology is relatively popular in the agrifood industry but its uses are spreading as the industry implements digital technologies in its production processes, in the so-called Industry 4.0. One specific example of how this technology is used is in repairing breakdowns. When a fault occurs, operators can use augmented reality goggles to follow the steps contained in virtual instruction manuals that are projected onto the lens to help resolve the incident. The glasses recognise the different parts of the machine and visually indicate to operators where they should act to solve the specific problem.

    There are numerous examples of new digital technologies being applied in the agrifood sector. We are witnessing a revolution that is destined to transform the different links in the food chain: from the exploitation of data and the use of drones to make harvesting more efficient to implementing blockchain technology to improve the traceability of the final products that reach our homes. In short, the future will bring us the Food Chain 4.0, a totally connected ecosystem from the field to the table.

Blockchain and cryptocurrencies: welcome to the new digital paradigm

Technological change will change the payment system as we know it, and blockchain technology will probably play a very important role in this process by facilitating the emergence of digital currencies. What are the key aspects of the technologies that will enable this transformation? Which cryptocurrencies are most likely to succeed?

Blockchain technology

Advances in cryptography, combined with the potential for data transmission and storage, have enabled the emergence of so-called distributed ledger technologies (DLTs). These are databases of which there are multiple identical copies distributed among participants on the network and which are updated in a synchronised and consensual manner. The great attraction of DLTs is that they allow data to be securely managed and shared, as well as saved, without the possibility for the information to be altered. The most well-known type of DLT is a blockchain, which organises information into blocks and regularly compares it with a ledger that cannot be deleted.

Blockchain technology is based on three key ingredients:

  1. Thanks to cryptography, each block of information is uniquely identified.
  2. Participants on the network must approve and validate all the information entering the network.
  3. The register is tamper-proof and immutable, making it extremely difficult to hack or modify.

Blockchain technology facilitates the emergence of cryptocurrencies, because by creating a shared register of all the transactions and establishing a decentralised method of validation, money can be digitally exchanged between users, directly (traditional payment infrastructures have a central intermediary, such as the central bank, a digital payment processing company, a mobile platform, etc.). The best-known application for blockchain technology in the financial world is payment settlements (in cross-border transfers, cryptocurrencies can play a valuable role as a bridge currency), as illustrated in the first flowchart.


How blockchain technology works
Blockchain, a rapidly-evolving technology that could facilitate the development of applications for mass use

One of the areas that is being worked on the most is in improving the scalability of blockchain payment systems, one of their key ingredients. The first initiatives that emerged were fully decentralised and public networks. In these cases, since all participants must validate the transactions, the number of transactions that can be processed is greatly limited (a prime example is that of Bitcoin, which processes 7 transactions per second compared to Visa’s 65,000) and the energy costs are very high. One of the solutions being explored is the use of permissioned networks, in which an administrator controls the network and decides who can participate in it. The advantage of such networks is that they are more scalable and allow transactions to be validated much quicker, although they are more vulnerable to attacks aimed at altering the ledger.

Beyond blockchain

It is important to clarify that technological advances in the financial sector go far beyond cryptocurrencies and DLTs, and they have enabled improvements in the speed and operation of payment systems. A good example of this is the spectacular advances made in mobile payments. Besides, as we have seen, blockchain technology has a lot of potential, although it would be possible to issue a digital currency without having to resort to using it. In fact, an authority with process centralisation powers, such as a central bank, could do so by developing an infrastructure based on the payment systems that are already in operation today.

The main areas in which the use of cryptocurrencies can prove beneficial are:

International financial transactions. Although blockchain technology is not the only alternative being explored in this area, it is a clear candidate for improving the efficiency of cross-border payments by reducing the costs involved and increasing the speed of transactions compared to highly-centralised systems.

Reducing the underground economy. Despite one of the main properties of cryptocurrencies being the anonymity of the transactions, mechanisms could be designed to facilitate the identification of illegal activities. For instance, they could be designed so that payments in certain areas or of a certain amount would not be anonymous.

They can promote financial inclusion in underdeveloped or emerging countries, where a significant portion of the population is unbanked (but could store cryptocurrencies in a digital wallet linked to their mobile phone).

Not all cryptocurrencies are made equal

According to the definition by the BIS,1 cryptocurrencies stand out because they are digital and because they allow exchanges to be carried out peer-to-peer. However, there are many types of cryptocurrencies. The so-called «money flower» helps us to classify different currencies, including cryptocurrencies, based on their properties in the most important areas: the type of issuer of the currency (central bank or not), its accessibility (widely accessible or restricted), its form (digital or physical) and its transfer mechanism (peer-to-peer or centralised).

  • 1. See Committee on Payments and Market Infrastructures (2015). «Digital currencies». BIS.
The money flower: a taxonomy

For example, depending on the issuer, there are three major classes of cryptocurrencies:

  1. Private cryptocurrencies: issued by an individual or private entity.
  2. Central bank cryptocurrencies.
  3. Hybrid solutions (synthetic cryptocurrencies): the central bank is the issuer, but a set of private entities would be in charge of customer interaction and innovation (in advanced economies, the natural candidate would be commercial banks).
Central bank cryptocurrencies and private cryptocurrencies: pros and cons

A priori, if a central bank ends up issuing a cryptocurrency, and it has a well-defined regulatory framework and there are no doubts over its security, it is highly likely to be accepted as a widespread form of payment. Being backed by a public institution that cannot fail, the mere fact that a fraction of savings and transactions switch to being carried out with the «crypto» version of the currency should not affect its value. For private cryptocurrencies, in contrast, it is harder for them to maintain a stable value since it depends on their degree of acceptance and adoption. Given that this can change suddenly, their value tends to be more volatile.

In any case, proposals are emerging that attempt to overcome this disadvantage. So-called stablecoins seek to solve this pitfall by setting what is effectively a fixed exchange rate between the cryptocurrency and an asset with a stable value (such as the currency of an advanced country). Libra, the cryptocurrency proposed by Facebook, falls under this family of cryptocurrencies.2

Arguments are often made in favour of developing cryptocurrencies backed by a central bank that could complement traditional monetary policy tools. As an example, setting an interest rate on the digital currency would broaden the range of instruments available to the central bank.3

However, the introduction of cryptocurrencies issued by central banks would also present risks given that they could contribute, at least in part, to reducing intermediation in financial activities:

  • If a portion of household and business bank deposits were converted into cryptocurrencies not managed by financial intermediaries, the supply of funds available for lending would diminish. This would tend to increase the cost of credit, as well as giving central banks greater prominence as structural suppliers of liquidity to the system.
  • The existence of such central bank cryptocurrencies would increase the volatility of flows between bank deposits and cryptocurrencies in times of uncertainty or when doubts arise over the solvency of a financial institution, thus posing a risk to financial stability.
  • The degree of financial disintermediation is critically dependent on who holds custody of the digital wallets for the cryptocurrencies. If it is the central bank, individuals could hold accounts directly in the central bank, which would aggravate the risk of disintermediation and financial instability. It would also be possible for financial institutions unrelated to commercial banks to perform this role; this would not eliminate financial intermediation but it would pose major challenges: how would such entities be regulated? Would the wallets be protected by a deposit guarantee?...
