Elena: Hello, everyone. My name is Elena Rossi, and I’m here today to talk to you about my experience running an organic olive farm in southern Europe, and how environmental changes are affecting our work. Most people assume I’ve been doing this my whole life, but I actually spent ten years in marketing before I decided to change my lifestyle and take over my grandfather’s farm. It was a steep learning curve, I can tell you!

When I first arrived, I had to learn about the land. We initially thought the rocky earth would be ideal, as olives are famously hardy, but it turns out the patches of clay provide the perfect nutrients for our specific tree variety. So, we focused our planting efforts there.

Farming is heavily dependent on the climate, and olive trees, although tough, are incredibly vulnerable to anomalous weather patterns. We were fully prepared for a severe summer drought, which is an increasingly common event here. However, it was a sudden winter frost that really did the damage this year. It caught us completely off guard.

The timing of this cold snap was disastrous. Normally, the fruit matures slowly over the colder months, but the freezing temperatures suddenly arrested that development. It didn’t affect their colour, surprisingly enough, but it completely stopped them from achieving their full ripeness. As a result, our overall yield was significantly lower than we had anticipated.

Aside from the weather, we also have to deal with pests. A lot of traditional farmers use chemical sprays to protect their crops, or simply rely on local birds to eat the insects. We wanted an eco-friendly approach, so we’ve adopted a biological control method by releasing a specific species of wasps that naturally prey on the olive flies. It’s been remarkably effective.

When it came to the harvest in late autumn, we had a difficult choice to make. You can use large mechanical shakers to bring the fruit down quickly, but they can easily damage the delicate bark of the trees. So instead, we laid down huge nets and gently coaxed the fruit down by hand using wooden rakes. It takes longer, but it’s much better for tree health.

Water is another huge environmental concern for us, especially with changing climates. We used to rely entirely on rainwater collected in a deep well on the property. However, to be more sustainable and precise, we recently invested a lot of money in a high-tech irrigation system. It monitors soil moisture and delivers exactly the right amount of water to the roots.

Once collected, the olives need to go to the press immediately. Some people think this rush is to preserve their nutritional value, but in fact, it’s to guarantee the absolute best flavour. If olives sit around in boxes, they begin to ferment, and the resulting oil tastes terrible.

After pressing, there is a lot of solid waste left over, like crushed pits and skins. We experimented with using it as animal feed for a neighbouring farm, but it wasn’t very successful. Now, we process it into a rich fertiliser, which goes straight back onto the fields to nourish the next generation of olives.

Looking ahead, we want to reduce our environmental impact even further. I originally planned to open a local farm shop to cut down on transport emissions, but I’ve decided to focus on building a dedicated website to sell our organic oil directly to consumers nationwide. It seems like the most efficient way to share our hard work with the world. Thank you for listening.

Leo: Hi everyone. My name is Leo, and I’m an agriculture student. I’m here today to talk about my recent work placement, where I studied the environmental impact of farming. I initially looked at spending my summer working on a huge farm in southern Spain, which sounded great. However, I ended up taking a placement in a beautiful valley in Italy, which is famous for its ancient olive trees. It turned out to be the perfect location for my research.

Many people assume that managing an olive grove is just a matter of pruning the branches and harvesting the fruit at the right time. Actually, our primary focus was monitoring the weather conditions, because that dictates how healthy the trees will be and how vulnerable they are to disease. We spent hours every day recording temperature and humidity levels across the estate.

Of course, climate isn’t the only challenge. Olive trees can attract specific agricultural pests. You might expect mammals or birds to be the biggest problem for the farmers, but actually, the most notable threat we faced was the olive fly. These tiny insects lay their eggs inside the growing fruit, which can devastate an entire crop in a matter of weeks.

And it wasn’t just flies. The trees also attract certain caterpillar species. We initially thought beetles were causing the mysterious holes we started seeing in the foliage, but we soon realised these crawling insects were the true culprits. They chew through the young leaves, severely stunting the growth of the trees if left unchecked.

These pests can completely ruin a harvest if they aren’t managed properly. Some farmers worry about the size of the fruit decreasing, but the real issue is that the insect damage gives the oil a rather bitter taste, making it impossible to sell to consumers. It completely destroys the premium quality the region is known for.

So, how do farmers deal with this? In the past, they would just use heavy machinery to clear out infected areas. But the standard practice recently has been to rely on chemical sprays to kill the pests. Unfortunately, this causes terrible harm to the surrounding environment, killing beneficial insects and damaging local biodiversity.

Because of this, we wanted to find a greener, more sustainable solution. My professor suggested introducing predatory insects that would hunt the flies, but instead we focused on encouraging wild birds to settle in the grove, as they eat the pests naturally. We put up nesting boxes all over the farm, and it worked brilliantly.

We also used physical barriers to protect the crop. I spent days setting up wooden fences around the perimeter, though they didn’t do much to stop flying insects! What really made a difference was hanging plastic traps from the branches, which caught thousands of flies safely without the need for toxic substances.

By avoiding artificial pesticides, we noticed a huge improvement in the local ecosystem almost immediately. We were hoping to see better soil quality over time, but the most dramatic change was the purity of the drinking water in the nearby village. Without the runoff from agricultural poisons, the local streams became completely clear again.

So, what’s next for me? Well, my tutor asked if I wanted to write a magazine article about our findings. However, I’ve actually agreed to help film a documentary about sustainable agriculture, which is incredibly exciting. I hope it will encourage more farmers to adopt eco-friendly pest control methods in the future.
