Water politics in the Nile Basin wide ramifications both for regional and global developments. The following table sort of demonstrates the water availability in each country within the Nile basin, and researchers' estimates of decrease in water availability to these countries, due largely to an increase in the countries' populations. Sudan also has hydraulic potential and has created four dams in the last century. This has resulted in the development so far of 18,000 km² of irrigated land, making Sudan the second most extensive user of the Nile, after Egypt. While Egypt is highly dependent on the Nile, there are factors that may lead to the
