The COVID-19 hangover has left us with a supply crisis with long queues (not only at the supermarket) that has increased the prices of equipment and all kinds of components. In addition, the armed conflict between Russia and Ukraine has led to an energy crisis with gas prices rising steadily.
Faced with this uncertainty and the growing fear of being cold in winter, some neighbourhood communities have started to connect to district heating networks (or heat networks). In Aranda, for example, 1950 homes will be connected to a biomass thermal network. The same is happening in Valladolid, where new heat networks are being installed in the neighbourhoods of Huerta del Rey, Parquesol and Villa del Prado. In other neighbourhoods, according to RTVE, residents’ associations are deciding to turn off central heating in response to rising prices, which could lead to an increase in the number of people living in energy poverty. In this context, the latter would mean people staying cold in their homes for fear of a high energy bill.
But, what are heat networks?
Heat networks or district heating networks are heat (or cold) production facilities that supply energy to each dwelling through underground pipes. Among the major advantages, compared to individual systems (the usual household boilers), are that heat networks allow the integration of renewable energy sources to increase independence from external fossil fuels, reduce emissions and lower costs for end-users. Other benefits include the removal of individual equipment from indoor spaces, which means more usable space available inside homes, and being able to offer a supply service independent of fossil fuels (and their price rises). Their main disadvantage is that they often require extensive work to prepare for the installation of pipework, traditionally involving the construction of large production plants with tall and aesthetically unattractive chimneys, and are simply not known to the general public, nor the benefits they can provide (especially in the case of Spain).
Then, affect the urban landscape of cities?
The answer is not necessarily. The New European Bauhaus (NEB) initiative aims to improve the quality of life of citizens through the joint promotion of the principles of Beauty, Sustainability and Inclusion in our environment, which is equivalent to good, beautiful and for all.
These principles focus on reconnecting with nature, regaining a sense of belonging and fostering participation, sustainability and circularity. In the case of heat networks, this holistic approach can be achieved in different ways.
As regards the sustainability pillar, the use of renewable energy sources (geothermal, solar thermal, biomass, biogas, recovery of surplus heat from industry) can be increased in thermal networks, as is being done at a general level in the sector to reduce CO2 emissions and other pollutants, but also, for example, through the revaluation of ashes or forestry waste.
As regards the social dimension and inclusion, by integrating more sustainable alternatives and supplying heat or cooling to a large number of households, affordable, secure and flexible heat or cooling supply can be promoted, thus reducing cases of energy poverty. In addition, digitalisation and the combination of networks with energy communities promote citizen participation and inclusion in the energy transition, where they can discuss, give feedback, engage in demand-side management strategies and even encourage users to become prosumers of heat.
But how can heat networks be made beautiful? At CARTIF, we have found that, through the generation of green spaces (such as parks) or multi-purpose spaces, it is possible to make the power plants beautiful spaces integrated into the urban, cultural or educational landscape. In addition, it is possible to reduce the visual impact of heat networks by burying the installations, and thus also the possible social rejection associated with the aesthetic component of these supply networks.
A case study in Heerlen, the Netherlands.
A very illustrative example of the successful application of the New European Bauhaus principles to heat networks is the network in Heerlen (Netherlands), which supplies 350 households with heat and cold thanks to geothermal energy. This network has boreholes at different temperature levels that allow it to provide heat of around 40°C in winter and 16°C of cooling in summer. The installation uses old coal mines as underground thermal storage and also uses surplus heat from a nearby steel industry, which would otherwise be lost to the environment. This could only be promoted in Spain if the houses were first insulated in order to lower the temperature required for heating and thus lower the temperature of the district heating networks. In Heerlen, at each substation each user would have an auxiliary heating system (which could be heat pumps) to meet their thermal demand. Thus, its generation is sustainable and guarantees affordable prices for citizens.
Moreover, the network’s generation plant has a modern and innovative aesthetic that blends in with the urban environment and is part of a multifunctional building that includes a supermarket, a café, a conference room and a library. In this way, far from having a negative visual impact or provoking rejection, it has become an iconic meeting point in the city.
All this work on heat networks towards a more sustainable, inclusive and beautiful future is possible thanks to the fact that CARTIF is participating in several projects studying heat networks from different perspectives. Among them, REUSEHEAT and REWARDHEAT, where new generation heat networks are demonstrated with the integration of heat recovery from different sources, a project together with the JRC to study the NEB perspective on heat networks in Europe, or the NetZeroCities cities mission platform, where CARTIF will support cities to promote this kind of initiatives.

Economic crises, conflict, inequality and subsequent food price rises make difficult to access adequate food and the lack of availability creates even more inequality. All these situations are affecting food security and preventing a path towards ending hunger and malnutrition and meeting Sustainable Development Goal 2: Zero hunger, ending all forms of malnutrition and ensuring access for all people to a healthy, nutritious and sufficient diet. The reality right now is that 3 billion people cannot afford even an inexpensive healthy diet.
According to the Food and Agriculture Organization of the United Nations (FAO) monitoring of key indicators of food security and nutrition, three major drivers have been highlighted in what is happening; conflict, climate variability and extremes, and economic slowdowns and downturns, compounded by the underlying causes of poverty, high and persistent levels of inequality e.g. in income, productive capacity, assets, technology, education and health (FAO, 2021)2
We cannot ignore the seriousness of the situation and the need to take part in action to address the global food insecurity and nutrition situation. It goes without saying that food systems are the driving force to end food insecurity and the prevalence of malnutrition.
Several factors affect the cost of food and thus food security through food systems, food production, supply chain and food chain environments, as well as consumer demand and food policies. Moreover, we cannot think in each factor that are affecting both, the food systems and the external events that are shaping the current situation, in an isolate way.
The rate of growth of food insecurity and prevalence of all existing forms and malnutrition indicate a trend far away from the 2030 target. Moreover, given the complications arising from the current political and economic situation and the lasting effects of the Covid-19 pandemic. Actions are more than necessary to achieve resilience to destabilising factors and to ensure that food systems can deliver affordable, healthy, inclusive and sustainable diets.
We need to focus on ensuring that development, innovation and economic growth reach everyone and #LeaveNoOneBehind. This is the slogan with which FAO wants to raise awareness on this World Food Day (16 October) of the serious global problem of food insecurity and malnutrition and the need to work together to create a better and more sustainable future for all.
To be part of this action, we can, for example, rediscover ourselves as part of the process and of the system, learning about sustainable diets, changing the way we eat, being part of the regeneration and transformation of the food system that is more than necessary to achieve a sustainable future. The challenges we face and the analysis of the causes and interconnections allows us to better understand global actions to establish new ways of doing things, and a unique learning opportunity for future situations. We have a path to follow in which no one should be left behind and we should establish innovative mechanisms to cope with the variability of factors that hinder their functioning. Driven by policies aimed at favouring and protecting the food and natural environment that promote behavioural change in the chain and in the consumer as part of it.
We, at CARTIF, are already part of this change by contributing to the transition of food systems in 12 pan-European cities through the FUSILLI project.
#WorldFoodDay2022 (one of the most celebrated days in the UN calendar of activities) aims to raise awareness of the need to join forces to create a better and more sustainable future for all.
When we talk about the word map, the image of a drawing representing countries and oceans comes to mind. For the most veteran of us, maps can bring back memories of the times when we used to have those folded maps in our cars with the roads of Spain. We can even evoke those old maps, practically works of art, where the names of ports and sea towns were crammed on the coastlines, while in the waters we saw painted mermaids and sea monsters. However, we should aso think of maps as one of the most attractive and useful means of providing any kind of data that has a spatial relationship to each other.
In its simplest and most traditional concept, a map is a graphical representation that shows an measurable entity and object (e.g. road, city or even a continent) at a scale that can be represented on a physical medium (a piece of paper or a computer screen). It´s true that concepts and ideas that go beyond actual physical spaces also fall under this definition, and the distances shown by certain kinds of maps may not be something measurable, but rather that these representations show things like ideas or processes, as in the case of concept maps. However, these other types of maps are further away from the concept addressed in this post, where we will focus on the more classical definition, but without renouncing the advantages provided by modern technology (in this case, the most recent programming languages).
In cartography, maps are used to represent geographical entities in different locations considering different representation systems. These entities, in addition to their geometry, can include distances, altitudes, and a long list of attributes that help to improve their representation. However, over time, maps have been used to represent characteristics or attributes of the elements, statically or dynamically through their spatial relationship with a geolocated entity. As an example, we could put a map of the people living in a certain region (population density), or of the voters of a political party, or of the per capita income of the cities represented.
The data we refer to are ultimately qualities or values that are relate spatially or not to the elements represented on a map. Therefore, we can speak of data represented on a map, although the reality is that it is the whole that serves the intended purpose: the data have meaning not only in their numerical value, as we have in the case of a simple list of data, but also in their positional value, where the relative position of those data on the map is what gives them sense and meaning, not only to themselves, but to the whole.
Practical use of data in maps
One of the technological fields where it is necessary to work with data and their relationships between them is the programming of software oriented to data visualisation. Without departing from the classic concept of map, it is of great importance to use these tools so that the users of the software (or the people who visit the website) can have the data available, in a clear and accesible way, and above all, so that at a glance they can get an idea of the set of data is being displayed at the moment.
There are a number of design tools for implementing interactive maps in both desktop and web applications. The most popular of these are, on the one hand, interfaces that bridge to existing desktop applications (e.g. applications using ArcGIS modules), and on the other hand, libraries for handling embedded maps in popular programming language applications, such as the Leaflet library.
The Leaflet library was launches in 2011 by the Ukrainian Volodymyr Agafonkin. This library is designed to work with JavaScript, and shows its usefulness in web applications for both computers and mobile devices, thanks to its small size (42 KB) and its good implementation, which makes it really easu to use from sides of the application, both by the user who browses the map, and by the programmer who writes the code that allows the map to do what its needed.
In addition to the above and considering the programming of interactive interfaces, it is important to have a library that allows not only to work with Leaflet, but also to use compatible components and help to integrate the whole set in a practical and easy to program application. In this case, the most popular and widely used library is React. And working with React, the best way to use Leaflet is through the integrated react-leaflet library, which will allow us to use each and every one of the features of this library, using the way React itself works.
This way of working with React, to give a brief outline, requires interacting with the objects in the code either through functions or using the concept of classes, understood in a similar way to that used in what is known as object-oriented programming. And this is how Leaflet works, highlighting the use of two concepts called the view and layers:
The view is the maps´s own sub-interface, which in turn contains all the uses and functionalities. For example, we could have buttons to show and hide data layers, zoom and search the map, and so on.
Layers are objects that contain the link to a specific dataset, as well as functions and properties that belong to the layer.
A view can therefore have several layers, which are the layers that contain all the data shown on the map. The map has one or more data layers, which show the information superimposed on the corresponding base layer.
To understand this concept a littele, a simple image of something that could be equivalent to this idea is the use of “transparencies” ( or “acetates”), which were used in the past to show slides: imagining an opaque sheet where a map is drawn, on it we can superimpose those transparent sheets, where our data is painted, in the form of polygons, marks, icons, arrows,etc. We can even superimpose several of these sheets, and we would see the data on top of each other, but all of them on the lines of the fixed map. The fixed map would be what we called before “base layer”, and the acetates would be acetates mentioned will be the data layers.
From CARTIF, we work on the implementation of solutions that use these technologies for the visualisation of geolocated data. As an example, we should highlight the ReUseHeat andePARCERO projects, where two applications have been developed for the management of geolocalised data. In ReUseHeat, the statistical visualiser allows to observe the sources of unused heat in hospitals, waste treatment centres, data centres and underground passenger transport. The base layer of the map belongs to OpenStreetMaps, and the data on potentially usable energy has been obtained from surveys carried out within the project. An interesting detail of the visualiser is to see how visualised objects are grouped into bubbles, which are broken down by zooming in on specific areas, improving the visualisation of the dataset. And all this is achieved through the use of Leaflet.
In the case of the ePARCERO project, whose prototype visualisation is still pending publication, the map is only one part of the tool, although it is the most important one. The map, which is coordinated with the data table at the bottom of the screen, as well as with filters on the left, shows the parcels selected as candidates of interest for users looking for parcels with certain characteristics, and which are currently not in use. The map allows to switch between two base layers, one the classic OpenStreetMaps one, and the other with the ortho-photo of the National Geographic Institute. As added details, apart from the pop-ups of the data when you click on one of them, the map auto positions itself when you choose a locality and makes the corresponding auto-zoom.
Present and future of interactive maps
As we have seen in the two previous cases, the usefulness that this type of tool has when displaying information on the screen is appreciable, going beyond the traditional visualisations in which the maps on web pages were only a pre-generated image, or that had to be generated each time data was modfied. Now, maps generated using Leaflet change, adapt, and are a dynamic tool on which to look at various data sets, and always serve the needs of a user who receives visual information that maximises its usefulness in this way. Most importantly, it allows the user to have no knowledge of maps, just a computer mouse and the curiosity to discover the data offered from the interface.
The future prospects for this technology offer new levels of detail in maps and new media to visualise plans and maps in three dimensions, beyond flat screens, allowing direct interactions with the represented element, as can be seen in the gradually more widespread use of virtual reality devices. But for the time being, the visualisation technology used more than meets expectations and proves its usefulness for the general public. From the Energy Division, we hope to make it as easy as possible for users to select and check data in increasingly comfortable and user-friendly interfaces.

Have you ever wondered what forests were like in the past? If suddenly a Templar travelling on horseback through a forest were to cross a rift in time and appear in the same forest today, would he notice difference? Would he see something strange? He probably would. And the fact is that the management of our forests and the relationship we establishwith them has evolved or changed over time.
At the beginning of Ridley Scott´s film “Kingdom of Heaven”, there is a scene shot in the Segovian forests of Valsain. In a fight that takes place on the banks of a river, the backdrop is an almost monospecific forest of Scots pine (Pinus sylvestris). Would it be strange to find 12th century Templars in a forest of this species? Not at all. In fact, we know that it is a species widely distributed throughout the northen hemisphere over time and quite abundant. But, despite being a native species, it is not a natural forest, as the distribution of tress seems to have certain “order”.There is a relative abundance of fairly young exemplars (the trunk is not very large in diameter) growing close together, with very little space between them. Behind this distribution is the hand of man, and in a productive system such as the Montes de Valsain, trees are planted in such a way that they grow tall, straight and as quickly as possible. Furthermore, the scene takes place near a river, where we might expect a riverside forest, but instead, this type of zonal forests has been displaced to favour the growth of conifers. It is therefore a forest under forest management.
But this management isn´t something relatively current at this time in Segovia. There are, in fact, documents that accredit management policies dating back to the 16th century: in an order issued by the crown, it was specified that
“”that all the dug-up areas be levelled and that horse manure be poured in, and that all the trunks of the felled pines and oaks be uprooted and removed (…) and the resulting pits be levelled ” 1
We can say that,for several centuries, management strategies aimed at soil conservation, pest management and obtaining raw materials have been applied in certain forests in our country.
Meadows are another good example of “artificial” forest that responds to the human management throughout history. And in this case, it is even older: our most emblematic landscape, which occupies some 4 million hectares in the Iberian Peninsula, dates back to the Paleolitic2.
But it has been in more recent stages of our history that the most dramatic changes in forest management have taken place. Traditionally, the forest has been a source of wealth, food and energy for towns and cities, which in itself meant sustainable management. In many cases, need generates dependence, and dependence is what drives conservation. However, the rural exodus to the cities, the appearance of new alternative materials to the use of wood, new forms of energy, or the introduction of exotic species for industrial exploitation, led to a change in the management of forests and agricultural land, which has contributed to the deterioration of the rural landscape, the health of the forests and the lack of protection of the soil.
There came a time, therefore, when there was a need for organised forest management planning, a common strategy based on forest knowledge, the green economy and sustainability. In response to this challenge, the first forest governance bodies and tools emerged in the mid-19th century. During this period, for example, some figures were created, such as the Forestry Catalogue (1862), the First Forestry Law (1865) or the Public Forestry (1989) 3 .
Some of these tools are still in use today. But iberian forests are facing a new challenge that is motivating the need for a major change in forest management strategies. Climate change is putting the survival of our forests to the test and calling into question the way they are managed.
Larger forest fires are becoming more frequent and virulent. The accumulation of drier fuels, vertical and horizontal continuity, and persistent low humidity and intense heat make the spread of fire intensify and render the fire inextinguishable. On the other hand, forest pests and diseases proliferate more easily in individuals weakened by heat and drought (or fire) and spread to new geographical areas due to climate change.
And how do we face the future? We need to make changes in management and management strategies that are able to respon to the climate challenge of the present and the future. Thanks to technological advances, we have very powerful tools for data collection, modelling and prediction to bring adaptative forest management to a “virtual” level. Satellites, drones or sensors are the new working tools in the forestry engineering with which detailed and almost real-time data on the behaviour of forest can be obtained. But we also need to look back and recover traditional uses of the forest that allow us not only to protect it, but also to generate a sustainable local green economy as the forest did in the past, but with the advantage of being able to apply current technologies and knowledge.
To this end, it is essential to make progress in research and knowledge of forestry science and other related sciences, so that our forests endure over time and so that the forest that was the setting for historical films is not the setting for a dystopian future
At CARTIF, we work on projects that makes our forests better prepared and adapted to face a future marked by climate change. An example of this is the FIREPOCTEP project, which works to develop forest management strategies to achieve greater resilience to forest fires, while generating resources to support a local green economy. We also work on the early detection and control for emerging diseases, such as Phytophthora spp. in projects such as SUPERAand ForT-HIS.
We have already spoken on numerous occasions about the impact of cities on energy consumption and emissions generated to the environment. And consequently, also of the important role that they have to play in the necessary transition towards climate neutrality, the ultimate goal of the European Green Pact for our continent (as my colleague Rubén Garcia pointed out in a previous post, the aim is for Europe to be carbon neutral by 2050).
The road to this neutrality is paved with many interventions, larger or smaller, and covering a wide range of areas (mobility, energy, building rehabilitation, citizen involvement; digitalization…). District or city scale projects -Smart City- funded by the different European Union programmes (from the 7th Framework Programme, through Horizon 2020 and the current Horizon Europe) work on all these dimensions with the idea of generating real demonstrations, and showing the path (or possible paths) that other cities can follow. Obviously, experts in different fields are needed to cover the various areas of competence covered by these projects.
In CARTIF we have been coordinating and working for many years in numerous projects along these lines, and also participating in many of the areas of work of these giants, which are so much in variety of activities as in the breadth of the time scale.
Recently one of these “lighthouse” project in which we have been working during years has finished, SmartEnCity. 78 months of work shared by 38 partners of 6 different countries in a project funded by the Research and Innovation Programme Horizon 2020 of the European Union, and coordinated by Tecnalia, in which it has been intended to make real the vision of convert our european cities in intelligent and zero carbon emissions.
In the project SmartEnCity three lighthouse cities has participated: Vitoria-Gasteiz in Spain, Tartu in Stonia and Sonderborg in Denmark. In all of them different intelligent and innovative solutions have been deployed in different areas with the idea of reaching the desired neutrality.
As a finishing touch, the last 14th and 15th of june, the project celebrated its Final Conference at the Europe Congress Palace, in Vitoria-Gasteiz. More than 120 participants attended the two-day event during which project results and plans for a carbon-free future were presented through keynote speeches, presentations, discussion sessions and moments of interaction by thematic areas.
I had the honor of participating and moderating one of the discussion tables that focused on one of the aspects in which CARTIF has been working for years and in which we have extensive experience: monitoring and evaluation. A key aspect to quantify the real impact that these projects achieve. In this case we tried to address these often difficult aspects in a way closer to the audience, sharing the experiences of different experts and projects around the most important aspects to take into account when evaluating project activities, the major problems encountered, solutions implemented and, finally,main lessons learned. I was lucky enough to share the debate with my partner Javier Antolin, who represented the REMOURBAN project, coordinated by CARTIF and which counted with Valladolid as one of its lighthouse cities. MAtchUP, ATELIER, Replicate and Stradust were also present.
One of the common aspects that we could all see is the enormous importance of citizens in the viability and success of these projects. This has a direct impact on the evaluation results and process itself. The transition to emission-neutral and sustainable cities in the broadest sense of the word can only be achieved if we, the citizens, are involved in the transformation process. If we are not barriers but vectors of change. If we go from being spectators to main characters.
From CARTIF we continue and will continue working on projects of theSmart Cities area with the idea of moving towards the horizon of sustainable cities. Will you join us on the way?
The world nowadays is immersed in a deep digital transformation change, whether we like it or not. Moreover, it seems the logical order of human evolution, because human development, is linked to technological development, since the “discovery” of fire, or the first rudimentary tools, till the outbreak of Internet or the spatial exploration. This change process, or better said revolution, not only concerns individuals, but also involves companies, that are completely immersed in this revolution for years: the 4th industrial revolution.
“We are on the brink of a technological revolution that will fundamentally change the way we live, work and interact. In its scale, scope and complexity, the transformation will be unlike anything that humankind has ever experienced before”
– Klaus Schwab, author of “The fourth industrial revolution” –
Within this revolution there are several key aspects, one of them being digital transformation. A concept that many people associate with digitalisation, a fundamental part of digital transformation, but which doesn´t capture this new, broader and more complex reality.
This term is often associated with the integration of digital tools such as a CRM (Customer Relationship Management), an ERP (Enterprise Resource Planning) for production management,etc. But in reality, is a much broader concept, which can be defined as a process that consists of orienting business activities towards the application of emerging technologies, and for this it is necessary to go through a process of cultural and organisational change and, finally, the application of new technologies throughout the organisation.
Therefore, we could differentiate the concept of digitalisation (implementing digital tools in certain processes) from that of digital transformation, the latter being much broader, as it orients the company towards the implementation of new technologies and towards a change in the traditional way of working. Taking all of this into account, we can define Digital Transformation as the set of projects and tasks that allow the company to adapt to the new needs arising from the 4th industrial revolution. Tasks that must be orchestrated through a plan that encompasses the following aspects:
Change towards a digital culture.
Global training plan.
Organisational reorganisation plan.
Specific training plan.
Incorporation of new profiles.
Progressive technological plan.
Thanks to digital transformation companies achieve huge advantages proven to improve in a number of key business areas:
Generate new experiences for the client.
Improve the operative efficiency.
Generate new income sources.
Increase the quick response capacity in the face of changes in the market.
Create competitive advantages for the organisation.
Improve the internal collaboration.
Deepens the data analysis (Big Data).
One of the great revolutions of this digital transformation is Big Data and Artificial Intelligence. It should be borne in mind that in recent years, the amount of information available on the Internet has practically doubled every two years, and this trend will continue to rise. Thanks to this amount of information and new technologies such as artificial intelligence, machine learning, deep learning,etc. the world as we know it will change, as will the way we work, shop and relate to each other.
This new reality, which has become much more evident in the wake of the 2020 pandemic, has taught us that businesses that fail to cope with today´s rapid changes are doomed to disappear, just as species that failed to adapt to the melting of the last ice age did.
Today, digital transformation is not an option. Today, companies can no longer consider adapting to this new landscape, as there is no other way to renew themselves and increase competitiveness than by developing a digital transformation plan.
How can we help you from CARTIF?
At CARTIF we have committed ourselves to this task of helping companies, especially SMEs, which are the ones that have the most difficulties in this complex and changing world of digital transformation. Because we know first-hand that sometimes lack of time or lack of knowledge means that we do not make progress in these fundamental processes. That is why we have a plan to help you along the way. We have a Digital Transformation consultancy service that is completely free of charge for companies.
What this programme consists of?
After contact us for receiving information, we will send you a service request form, and once submitted:
We will visit or meet with the person reponsible in the company to carry out a diagnosis of the current situation, work methodology and digital tools used.
Based on this report, we will create a personalised action plan with different actions identified to improve the company´s competitiveness.
Finally, we will carry out a period of mentoring to accompany the company during the process.
These actions will allow the company to start or continue the digital transformation process generating a roadmap in order to be able to address it.
