Why soils are so important?

 

Like water and air, soils are essential for our current existence. Historically, soils have been a big component in the foundation of our societies, playing a big role in the creation of agriculture, leading to sedentarism and the development of our actual lifestyle. Soils have also played a big role in terms of migration, globalization, and economy, facilitating the connection and exchange of products and traditions between different countries. Soils hold huge biodiversity, being an essential foundation for worldwide ecosystem functions and one of the biggest mediators for photosynthetic organisms. Besides these facts, soils are great water filters, provide essential nutrients to plants, contains big amounts of organic carbon and are one of the primary regulators of greenhouse gases and temperature. Now 95% of our food is produced directly or indirectly in soils, making our existence dependable of them. 

 

My research interests focus mostly on soils because it is clear that soils are extremely important for human survival. Besides, soils are a huge component in the alterations of climate and food security. Still, human impacts have increased the degradation of soils, especially by erosion, contamination, carbon loss, salinization, and loss of biodiversity. That is why one of my goals with my P.h.D. research is to understand a little bit more the interactions of plants with soils and how climate and human stresses could alter these, impacting directly food security.
