More Rice with Less WaterMansha Fatima, India Global finalist, 13-15
In India, over 50% of people in India depend on agriculture, including rice cultivation, to make a living, but many farmers do not have the resources or knowledge to efficiently manage these crops. Even more alarmingly, many rice crops waste high volumes of water due to this problem, and farmers often overwater their crops, negatively impacting their own rice yields. Eager to find a solution, Mansha (15) of Hyderabad, India, wanted to create a low-cost way to monitor water levels in rice paddy fields as well as automate water levels for the best possible crop yields. She designed an automated irrigation system that waters crops based on their age, with the potential to save 30% of the water normally used per hectare of land as well as increase rice crop yields by up to 13%. Mansha looks forward to seeing her system conserve significant amounts of water while improving crops and minimizing financial stress and labor for farmers.
