The Journey of Sand: How the Yellow River Has Shaped Lankao County


China’s Yellow River carries large quantities of silt, which is deposited along the river’s lower stream and causes sandification. The increase in the population, the expansion of agricultural colonies, the surge in deforestation, the changes in climate, and the advancement of deserts have accelerated soil erosion and thereby the siltation problem in the river. This paper traces the journey of the sand to Lankao County, one of the locales most affected by the sand.
