🌱 New tool helps farmers and educators calculate soil erosion in seconds

NEST launches a free online simulator to raise awareness and support sustainable land management

At a time when climate change and unsustainable farming practices are accelerating soil degradation, the Spanish non-profit organisation NEST (Nature, Environment, Sustainability & Transformation) has launched a new online tool to help estimate soil erosion in just a few clicks.

The tool, which is now freely available on the NEST website, allows users to calculate the amount of soil that may be lost annually from a given area due to water erosion. By entering a few basic details – such as soil type, slope, vegetation cover or land use – users receive an estimate based on the well-established Universal Soil Loss Equation (USLE), widely used and validated by the scientific community.

The idea isn’t just to give a number,” the NEST team explains, “but to help people understand which factors influence erosion and how to reduce the risk through practical steps.”

Once the simulation is complete, the tool provides a brief interpretation of the result, along with a tailored recommendation. This way, users can quickly see whether their land is at low, moderate or high risk of erosion – and what action they might take, such as introducing cover crops, changing tillage practices or planting on contour lines.

Open access, with a professional edge

The simulator is free to use and designed for farmers, environmental professionals, students and educators alike. “We wanted it to be as accessible as possible, even for people without a technical background,” say the developers. “That’s why we’ve included guidance by climate type, short explanations for each factor, and a mobile-friendly interface.”

For those with more advanced needs – such as comparative reports, technical advice or planning support – NEST also offers a premium version of the tool, with access to deeper analysis and tailored consultancy. This option is aimed at larger farms, local authorities, and research or development projects.

Soil protection is everyone’s business

NEST is keen to highlight that soil erosion is often invisible, yet profoundly damaging. “When soil is lost, we lose the foundation of food production. Water quality declines, ecosystems suffer, and the landscape becomes more vulnerable to floods and droughts,” they warn. “That’s why we’ve created this tool – so anyone can take action, using the best available knowledge.”
