In the context of pressuring climate change, adopting plant proteins as a viable source of nutrients supports human health and plays an essential role in maintaining and improving soil health. This article explores the benefits of plant protein and their impact on sustainable agriculture and soil health.

What are plant proteins?

Plant proteins come from various sources and are essential for a balanced diet. Among the most popular sources are:

  • Legumes: lentils, beans, peas;
  • Nuts and seeds: almonds, chia, hemp, sunflower seeds;
  • Whole grains: quinoa, brown rice, oats;
  • Soy products: tofu, tempeh, edamame;

Benefits of plant proteins

  • Low environmental impact

Plant protein production requires less water and land and generates lower greenhouse gas emissions than animal protein production. According to the European Environment Agency, transitioning to plant-based diets can significantly reduce the ecological footprint.

  • Improving soil health

Growing protein crops such as legumes can improve soil structure and fertility due to their ability to fix nitrogen. These plants contribute to increasing the content of organic matter and improving the microbial activity in the soil.

  • Crop rotation

According to FAO data, integrating protein crops into crop rotation helps prevent nutrient depletion and reduce the need for chemical fertilisers. This supports soil health, helps reduce pollution, and conserves biodiversity.

Application in sustainable business models

Regenerative Agriculture

Among other concepts, the InBestSoil project promotes regenerative agriculture techniques that improve soil health and increase farm productivity. Using protein plants can: 

  • Improve soil structure and fertility;
  • Reduces erosion and nutrient losses;
  • Increases biodiversity in agricultural systems;
  • Support circular economy;
  • Waste reduction and reuse of farm products.

Circular economy

According to the European Commission, the circular economy can transform how we manage resources and waste, contributing to long-term sustainability.

Integrating plant protein into business models can support the circular economy by reducing waste and encouraging the reuse of agricultural products.

Successful stories

Urban Gardens

Urban gardening projects that promote self-sufficiency and access to healthy food. These initiatives help create more resilient and environmentally conscious communities.

Agricultural Cooperatives

These are local initiatives that support small farmers and promote sustainable agricultural practices. Community-supported agriculture networks in Europe are crucial in fostering cooperation and sustainability.

Plant proteins are a healthy alternative to animal proteins and essential for soil health and agricultural sustainability. Projects like InBestSoil demonstrate how innovations in agriculture can transform how we grow and consume food and our environmental impact.

Education and awareness can accelerate the transition to a more sustainable and healthy diet, contributing to a better world for future generations.
