In Ukraine, reforms in the sector of water supply and sanitation have focused on centralising water supply and sanitation. Efforts have been made to decentralise water management, delegate to local authorities as well as increase supply in rural areas. This has been done through awareness campaigns, capacity building and innovative techniques of wastewater reuse. The key lesson learnt from this case is that IWRM principles need to be considered when planning for water infrastructure.
The Upper Guadiana Basin provides a classic example of conflict caused by the intensive use of water resources in a semiarid region. Since the 1960s, uncontrolled abstraction of groundwater to provide water for crop irrigation in the area has lowered the water table in places by up to 50m, causing the main river channels to run dry and some wetlands to become desiccated. On the other hand, the abstraction has also supported a booming agricultural economy.
For centuries the Upper Guadiana Basin has been irrigated with groundwater, resulting in a drop in the water table of more than 20 meters. Actions were taken to address this issue, including regulations restricting aquifer abstraction and economic incentives to encourage farmers to improve irrigation efficiency and plant alternative crops. The key lesson learnt is that surface and underground waters cannot be managed separately.
The Toledo River basin is increasingly contaminated due to unsustainable agricultural practices, Action was taken through a UNESCO-IHP project aiming to perform an integrated environmental assessment of agricultural and farming production systems located in the Toledo River Basin. By using a multi-criteria approach, it was possible to highlight the interactions and use of natural capital, human-driven resources, and ecosystem services supporting agricultural and farming production systems.
The lowland valley of Chancay-Lambayeque watershed is scarce of water resources, forcing farmers to irrigate with insufficiently treated waste water, resulting in severe health issues. Action was taken through the project “Future Development of San José farmer community: Wastewater” which was a collaboration between the private and the public sectors, aiming to illustrate alternative ways to irrigate. The most important lesson is that cooperation is an important instrument for development.
Uzbekistan is experiencing water scarcity, an issue which will be exacerbated with increased demand. Although policies exist, the water seldom reaches the end water users. To combat this issue, action has been taken by GWP Uzbekistan to conduct trainings and workshops on the dissemination of IWRM to encourage a participatory multi-sector approach. This case study illustrates the importance of public awareness, and the need for work to be conducted at all levels.
Irrigation infrastructure is crucial for economic development in Fujian. However, due to incomplete water management, the existing water facilities do not satisfy the current development. Action has been taken by the infrastructure department of Fujian provinces to cooperate with local farmers and organisations to explore participatory management and new mechanism of local water management. This case indicates that direct involvement of water users will result in rational use of water resources.
In the village of Parakar, untreated wastewater contaminated agricultural lands, jeopardised food safety and posed severe health risks. In 2010, the Parakar community supported by partners from the Country Water Partnerships of Armenia initiated and developed a demonstration pilot project for domestic wastewater treatment. Particular attention was given to community involvement. This case illustrates the value of small scale solutions.
In Australia, a new approach to water management was needed to allow imported water to be used for irrigation without increasing the salinity of the soils or groundwater. Action was taken to develop a framework to enable irrigators to identify and to manage the environmental risks associated with the use of River Murray water for irrigation. The key lesson is that a salt management strategy is relevant wherever there are plans to irrigate land.
With the collapse of the USSR, the water sector seized to be subsidised leading to deterioration of basic infrastructure. Action was taken to partially transfer the responsibility for operation and maintenance of irrigation systems to water users. Nonetheless, this has had limited success because it has been seen as an additional cost rather than benefit. This illustrates that for this to work, the returned benefits need to be higher than the costs.
