The Kedah Plain stretching from Sg Petani to Alor Star-Jitra where our rice bowl is located presents a suitable region to develop canals and inland waterway. This may not for economic reasons so much but to make use of the abundant water in the rivers, irrigation-drainage canals, lakes, wetlands and ditches - for beautification of the rice landscape, for tourist attraction and to instill love of water for generations to come.
