🌱 THEY STARTED WITH WHAT THEY HAD
High on the hillsides of Medellín, Colombia, some communities have spent years living with a difficult reality.
When heavy rain arrives, the same steep slopes that are home to thousands of families can become dangerous. Flooding, erosion and landslides have repeatedly threatened homes and neighbourhoods.
But instead of waiting for someone else to solve the problem, local residents began working on solutions themselves.
One of them is **Róbinson Velásquez Cartagena**, a resident of the Golondrinas neighbourhood in Comuna 8.
At his own home, Róbinson built a rainwater-harvesting system using the roof to collect rainfall and store it in large tanks. The stored water can then be used for things such as washing clothes and flushing toilets, while managing runoff that would otherwise flow down the steep hillside.
It may look like a simple idea.
But for a community living on vulnerable slopes, small solutions can matter.
And then came the trees.
In the nearby El Pacifico neighbourhood, **Nancy Elena Quiros Correa** oversees a community tree nursery measuring about **9 metres by 3 metres**.
The purpose isn't simply to make the neighbourhood greener.
The young trees are intended to help stabilise vulnerable slopes, absorb water when heavy rain arrives and increase biodiversity.
Nancy has personal reasons for taking the risk seriously.
She recalls rocks hitting and eventually collapsing a wall near her home around 2011. She also remembers a serious flood in the area in 2020 that affected homes and buildings.
For residents like her, climate change isn't an abstract discussion happening somewhere far away.
**It is something they can see on the hillside where they live.**
What makes this story remarkable is what happened next.
These individual efforts became part of a much larger community-led plan.
Residents worked with local organisations, universities and government agencies to develop the **Local Agreement for Inclusive Climate Action**, formally launched in 2023.
The plan includes eight nature-based approaches, including **rainwater harvesting, reforestation, ecological gardens and agroforestry**. Community members also helped identify local hazards and monitor environmental risks.
What began with people trying to protect their own homes has grown into something much bigger.
The work in Comuna 8 has helped influence climate and disaster planning across Medellín, showing that local knowledge can become part of city-wide solutions.
And perhaps that is the most powerful part of this story.
They didn't wait for a perfect solution.
They started with a roof.
A water tank.
A garden.
A handful of young trees.
And the belief that protecting a place begins with the people who call it home.
🌿 Sometimes resilience doesn't begin with a huge project. Sometimes it begins with ordinary people deciding to care for their own neighbourhood.
Would you trust a community-led approach like this to help protect your neighbourhood from climate risks?
