Description
Urban water demand is expected to increase by 50 to 80 % by 2050, often in regions where irrigation is also being expanded. These trends will intensify competition for water between cities and agriculture. The water supply of around a third of the world's surface water-dependent cities is already at risk due to competition with agricultural users, and this figure is expected to rise by 2040 as urban and agricultural demand continues to grow.
The reallocation of water from rural to urban areas is one of the most important measures to meet the growing demand for freshwater in cities and to cope with the effects of climate change and water quality problems. Reallocation occurs in parallel with the development of new water resources and demand management and is often pursued in conjunction with these measures. Cities often look to neighboring agricultural and rural regions as the main sources of urban water supply after local and cheaper sources are exhausted. The relatively large volumes, often low water use efficiency and low marginal economic productivity of water in agriculture have sparked a growing interest in the reallocation of water resources from rural to urban areas, although the nature of water use and water stress in urban areas is very different. In urban areas, only a small proportion of abstracted water is consumed, creating opportunities for wastewater treatment and reuse.
The redistribution of water from rural to urban areas is associated with different challenges and characteristics that are influenced by urbanization patterns and associated infrastructure and governance arrangements. Inter-basin transfers channel water from distant rural regions to growing cities, a phenomenon referred to as “hydraulic reach”.
This session aims to highlight the problems of interaction between rural and urban water management, identify the problems and discuss possible solutions.
