Biodiversity, Knowledge, and the Sky Above Cartagena

A weekend that proved people are hungry to learn

Last weekend, we had the pleasure of participating in the IV Feria de la Biodiversidad Cultivada, organized by AgroSimbiosisLab as part of the Cartagena Folk Festival in Parque de la Rambla.

What made this event special was not only its scale, but its concept.

Traditionally, festivals bring together music, food, crafts, and local products. This event certainly had all of that—wonderful food, local producers, artisans, and a fantastic atmosphere—but it added something increasingly rare: the opportunity to learn.

For three days, visitors were able to participate in a carefully coordinated program of workshops, talks, demonstrations, and hands-on activities created by members of AgroSimbiosisLab and collaborating organizations. The result was something genuinely inspiring: people didn’t simply come to be entertained. They came to engage, ask questions, discover new ideas, and actively participate.

And they did so in remarkable numbers.

Bringing astronomy into the conversation

At Astronomy Tours and Finca Astronómica, we were proud to contribute two activities to the festival.

The first was a series of solar observation sessions using both traditional optical solar telescopes and modern robotic astronomy equipment.

Many visitors had never observed the Sun safely through a telescope before. Throughout the day, they were able to see our nearest star in extraordinary detail: sunspots, surface activity, and the dynamic appearance of the solar atmosphere. Through dedicated solar equipment, visitors discovered that the Sun is far from being a featureless bright disk. Instead, it is a constantly changing, active world that shapes life on Earth in ways most people never realize.

The robotic systems added another perspective, allowing participants to see the Sun through advanced imaging technologies and understand how modern astronomy increasingly combines optics, computing, and automation.

For many guests, it was their first direct encounter with real astronomical observation.

The forgotten connection between astronomy and agriculture

Our second contribution was a talk exploring one of humanity’s oldest scientific relationships: the connection between the sky and agriculture.

Long before written calendars existed, people looked upward to organize life on Earth.

The appearance of constellations, the changing positions of stars, and seasonal patterns in the night sky provided reliable markers for planting, harvesting, navigation, and planning entire societies.

We explored how recognizable patterns such as the Summer Triangle and other seasonal constellations served as natural calendars for countless cultures across history. The ability to predict seasonal change transformed agriculture, allowing communities to move from simple survival toward stable civilizations.

In many ways, astronomy was one of humanity’s first agricultural technologies.

The discussion fitted perfectly within the wider goals of AgroSimbiosisLab, which seeks to reconnect people with the ecological and cultural systems that sustain us.

Preparing for the next great eclipse

The festival also provided an excellent opportunity to introduce visitors to one of the most anticipated astronomical events in Spain’s recent history: the total solar eclipse of 12 August 2026.

Many people are still unaware of what will happen, where the best observing locations will be, or how to observe safely.

Throughout the weekend, we helped visitors understand the path of the eclipse, what can be seen from different parts of Spain, how to prepare for the event, and why proper eye protection is essential. Judging by the excitement and questions we received, the eclipse is already beginning to capture people’s imagination.

A success that belongs to everyone

What moved us most, however, was not our own participation.

It was seeing how eager people were to learn.

Workshops about bees and honey production, traditional seeds, sustainable land management, medicinal plants, biodiversity, soil care, and ecological practices attracted enthusiastic audiences throughout the event. Visitors asked questions, stayed for entire sessions, shared experiences, and showed genuine curiosity about the world around them.

That enthusiasm is not something organizers can create.

It comes from the public.

And this weekend demonstrated that there is a real appetite for meaningful, educational experiences when they are presented in an accessible and welcoming way.

Looking forward

Events like the Feria de la Biodiversidad Cultivada remind us why collaborations between science, culture, agriculture, and education matter.

They create spaces where knowledge is not locked away in universities or research centers but shared openly with the people who can use it, enjoy it, and carry it forward.

Everyone involved—from organizers and workshop leaders to volunteers and participants—should be proud of what was achieved.

We certainly are.

Thank you to AgroSimbiosisLab, Cartagena Folk, the many collaborating organizations, and above all the hundreds of visitors who came with curiosity, questions, and a willingness to learn.

The future looks much brighter when people are excited about knowledge.
