¿Cómo lo invisible está cambiando la agricultura y el planeta? | Lina Valderrama | TEDxCali

Quick Overview

Lina Valderrama, inspired by her mother's agricultural legacy and driven by the need to create sustainable food systems, advocates for adopting microorganisms in agriculture to improve soil fertility, increase crop yields, and mitigate environmental damage caused by chemical inputs, demonstrating through research that these invisible allies can significantly boost productivity and support global food security.

Key Points: Valderrama's motivation stems from her desire to help the 3,000 million people facing food insecurity by transforming agriculture through sustainable methods. Research comparing sugarcane plants showed that those treated with microorganisms ('Con Aplicación de Microorganismos') developed significantly larger roots and stalks than those without treatment ('Sin Aplicación de Microorganismos'). The application of these beneficial microorganisms resulted in a 20% increase in sugarcane germination rates and led to larger, stronger root systems. The speaker contrasts her mother's empirical knowledge with scientific rigor, noting that her mother intuitively understood how to regenerate the soil without chemical contamination. The economic benefit is significant: optimizing fertilizer use by applying microorganisms leads to an estimated 6.8 tons more sugarcane yield per hectare. Valderrama pursued a PhD, driven by the conviction that this biological approach offers a viable alternative to conventional, chemically-dependent agriculture. The presentation concludes with a call to action for the audience to carry the idea of supporting biological solutions into their own lives and endeavors.

Context: Lina Valderrama delivers a TEDx talk titled "¿Cómo lo invisible está cambiando la agricultura y el planeta?" (How the invisible is changing agriculture and the planet?), sharing her personal journey from growing up in a rural environment in Colombia to becoming a scientist. Her talk focuses on the crucial, yet often overlooked, role of soil microorganisms in sustainable agriculture, contrasting traditional, successful farming intuition with the need for scientific validation and scale-up to address global food security challenges.
