My name is Mizuho Nakai.
I am 18 years old studying at an agricultural high school.
I play Japanese drums in the local entertainment club.
The Mabechi River runs through the town where I live, and it is a very beautiful place.
Heavy rain caused by a typhoon floods a river.This is what I think is one of the solutions for a sustainable future:
It is to purify domestic wastewater and use it for agriculture.
Let’s insert capillary barrier in soil for salt-damage control and water-saving agriculture
The annual cycle of dry and rainy seasons causes soil salinization to become major abiotic constrains limiting agricultural production in arid and semi-arid regions. With the climate change, population booming and increasing global food demand, developing countries are experiencing severe food crisis. The salinity issue remains as major challenge. We developed a low-cost water-efficient salinity prevention system through capillary barrier (CB). The objectives of our study were to introduce an artificial CB, which made up of lime (e.g., calcium chloride, converter slag, and plant and wood ash), gravel and plant residue. We found the salinization suppression without requiring huge amount of water by the CB application. This low-cost and water-saving system will surely pave a new path for sustainable agriculture.
