Samuel Cortese McLean
I grew up in Ecuador, one of the most biodiverse countries in the world, where I developed a profound sense of awe toward nature. This curiosity inspired me to explore the intricate biological systems that sustain life on our planet and to ask how we might harness these elegant and complex processes to build a more sustainable future.
From the microscopic elegance of metabolic pathways to the vast, daunting physical forces that shape our climate, I see endless opportunities to learn from nature and redefine our relationship with the environment. This belief has driven my academic journey and personal mission: to understand living systems and apply that knowledge to solve modern-day challenges.
I have conducted research in microbial ecology with an emphasis on conservation and agricultural applications. Currently, I am working on a project aimed at characterizing metabolic pathways in yeast and exploring their potential in other organisms.
Experiences like the Darwin 200 project have provided powerful inspiration, reinforcing my commitment to continue this path and to help raise awareness about how we can collaborate with nature—not exploit it—to create a better future for all life on Earth.
Area of Study: Soil Rehabilitation
The project is an exploration into how the people of Rapa Nui have related themselves with agriculture, and more specifically with the soil in their island. Which has led them to develop innovative farming methods to face the harsh agricultural conditions such as limited water, intense sun, and scarce nutrients. Over time, they used the abundant volcanic rocks to create stone gardens and Mana Vai, structures that preserved moisture, moderated temperature, and improved soil fertility.
These techniques sustained generations but were eventually abandoned due to the introduction of non-sustainable modern agricultural practices, like monocultures. This led to a considerable loss of traditions, resulting in the degradation of the native soil.
However, today there are several initiatives which blend ancestral wisdom and sustainable practices like reintroducing traditional crops, planting in dense and diverse arrangements, and using trees to restore water cycles and microbial health. These strategies, combined with the collaboration and education of the local communities, offer a path towards restoring soil health and agricultural sustainability, since Rapa Nui is not a place for mass production but for cultivating resilience and ecological balance.
