Description
The integrated approach to urban-rural water management requires interdisciplinary approaches and the bringing together of components that impact urban water management, such as stormwater and flood control, wastewater treatment, water supply and solid waste, and rural areas with watersheds, groundwater and agricultural activities. This interaction between urban and rural areas can be seen, for example, in the impacts caused by the disproportionate growth of urban areas. For example, the availability and quality of water in surrounding rural areas can be affected by excessive and uncontrolled water consumption and the discharge of untreated wastewater, which in turn affects the overall quality and availability of water.
A successful linkage between the urban system and the watershed requires social participation and integrated management to achieve optimal social, economic and environmental outcomes. This ensures that processes and outcomes meet sustainability requirements.
These topics are part of this session, with a particular focus on the extent to which integrated concepts can ensure efficient and sustainable use of water resources, both in planning and in the expansion of the urban area.

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.

Description
Agricultural production systems in transition between rural and urban areas, 'peri-urban agriculture', represent a unique and dynamic mix of agricultural practices. This transitional area is characterized by proximity to urban markets, diverse land use, and a mix of traditional and modern farming practices, opening up opportunities for innovative resource (re)use and economic synergies as well as adapted land use planning related to water resources and urban climate. A first step is to describe, analyze and explain the changing resources along the urban-rural continuum. Gradients such as population density, infrastructure, land value and natural resource availability, with their complexity and interdependencies, pose a challenge to realizing a sustainable transition of peri-urban agri-food systems.

Description
Innovation is pivotal for sustainable food production and development. Urban areas use and pollute a large share of hydric resources yet exert a high demand for agricultural produce. This might create tensions between different human activities particularly if local water sources must be shared as it’s the case for urban-rural transition areas. However, these potential tensions could also stimulate innovative solutions for efficient resource use. Controlled environment farming, as well as reuse of wastewater for irrigation and/or soil amendment, among other innovative food production systems, may provide a means for more sustainable transition to urban agriculture.

Description
Population growth as well as climate and land use change have affected water and food security, and therefore the wellbeing and livelihoods of millions of people. The identification of effective approaches to address these challenges requires a socio-hydrological understanding of the different conditions along the rural-urban continuum. Integrating the perceptions of local communities and assessing livelihood, food and water security impacts of technical solutions can help to develop tailored, sustainable solutions for water management and agricultural production that can alleviate the impacts of climate and land use change.
