Malnutrition often exists in the shadows of caloric abundance. While a community might have enough food to feel full, it frequently lacks the micronutrients essential for long-term health.
Sandra Mariya Sony, a student volunteer and a member of Kerala’s Balasabha, identified this gap and found a solution that requires neither a sprawling field nor expensive fertilizers. She found it in a shallow tray.
Sandra’s project, ‘Microgreens Cultivation: A Sustainable Nutrition Initiative,’ was a featured highlight at the LIORA 2026 Innovation Conclave. This event, held at the Kerala Startup Mission in Kalamassery, served as the culmination of a year-long journey for thousands of children. These young innovators are part of the Balasabha, a neighborhood-level collective for children aged 5 to 18, organized under the Kudumbashree Mission.
MEET THE YOUNG INNOVATORS OF KERALA
This article is part of an ongoing series by The Fourth Plate documenting the innovations of young thinkers across the Global South. We believe these grassroots prototypes hold the keys to a more resilient future. Our hope is that by highlighting these projects, we can capture the interest of entrepreneurs and startups ready to scale these sustainable solutions for everyday challenges.
Kudumbashree is Kerala’s state poverty eradication mission. It is a massive network of over 4.3 lakh children and millions of women working to break the cycle of poverty through local action. LIORA, which means ‘My Light,’ is the mission’s flagship innovation program. It is supported by the Udhyam Learning Foundation, which provided the technical mentorship and curriculum needed to turn simple ideas into viable social enterprises.
Sandra’s innovation focuses on the speed and simplicity of nutrient production. The project was carried out through organized teamwork among student volunteers, who utilize seeds like green gram, mustard, and fenugreek.
Instead of traditional soil, which can be difficult to source or manage in urban apartments, they use cotton cloth as a medium. This choice reduces the risk of soil-borne pathogens and makes the system incredibly light and portable. The process is straightforward: the seeds are soaked, spread evenly and watered regularly. Within seven to ten days, the microgreens are ready for harvest.
Sandra demonstrated that these tiny plants contain significantly higher concentrations of vitamins and minerals than their mature counterparts. By focusing on student participation, her initiative encourages a lifestyle change. It turns children into ‘nutrition volunteers’ who can promote eco-friendly food habits in their own homes and schools.
The technical success of the conclave was also bolstered by partners like TinkerHub, which provided volunteers to support the Balasabha members. This ecosystem ensured that projects like Sandra’s were not just scientific experiments but potential models for community-wide adoption.
The scalability of this microgreens project is what makes it a prime candidate for entrepreneurial interest. It requires minimal space, uses simple materials, and produces a high-yield, healthy product in a very short window.
As we look for ways to make our food systems more sustainable, Sandra’s model offers a decentralized approach to nutrition. It can be integrated into school lunch programs, community centers or even small-scale urban farming startups.
The value of the LIORA initiative lies in this exact intersection of youth creativity and institutional support. By giving children the platform to solve real problems, Kudumbashree and the Udhyam Learning Foundation are nurturing a generation of leaders who see sustainability as a practical reality rather than a distant goal.
Sandra Mariya Sony’s trays of green are more than just a project: they are a testament to the power of small-scale, high-impact innovation.
