Nick, 24, El Salvador - My idea is called Aquaponics. Aquaponics is very much like hydroponics but instead of using chemicals to supply plants with nutrients it uses fish and bacteria. Along with solar power this system is almost completely independent and can be placed anywhere (jungles, deserts, etc.). It is 100% organic and environmentally safe. It can provide an excellent source of nutrition from fish to vegetables and fruits.

Because it involves creating an artificial environment crop diversification has no limits thus providing a key opportunity for increased nutrition in rural and/or poor areas. Maintenance is extremely cheap and potentially can provide a steady source of income for poor families.
Thus, it could potentially provide subsistence living support, better nutrition, increase environmental awareness, and educational opportunities for children. The project is designed primarily to create a practical training curriculum to teach Aquaponic techniques to farmers but has many other broad applications as well.

The project includes the construction of a training system and primary training. With this new technique farmers will be able to farm year round, diversify their crops, feed their families, and do it all cheaply without impacting the environment.
