The major issues created by the floods were not only the destruction of crop lands and harvests, but also the loss of emergency grain reserves, because many of them were stored underground. According to the United Nations, the floods of 1994 and 1995 destroyed around 1.5 million tons of grain reserves,[26] and the Centers for Disease Control and Prevention stated that 1.2 million tons (or 12%) of grain production was lost in the 1995 flood.[27] There were further major floods in 1996 and a drought in 1997.[28]
