Much of the groundwater in the region has also become salty and unfit for agricultural use. Surface drains have been built to help solve these problems. Sindh's largest water project, the construction of the Gudu Barrage Dam, has provided water for irrigation into the dry desert areas of Pakistan. Where irrigation is not available, the Koli depend on what little rainfall there is. This region consists mainly of sand dunes with patches of clay.
Camels are their main mode of transportation.
Because these tribes live in drab surroundings, they often exhibit a vivid array of colors in their paintings and other artistic designs. Koli houses vary from region to region. Sadly, most of the people live in poverty. Less than half of the Koli are literate. Most of the Koli tribes drink liquor and eat fish, fowl, and pork.
