The Weihe River plays a central role in Shaanxi. However, rapid economic development has created many problems, including increased water scarcity, pollution and regional ecological environment deterioration. As a response, the Weihe River Basin Integrated Management Plan was developed based on the principles and approaches of IWRM, with the participation of many sectors. The significance of this case is the promotion of public participation and gradual improvement of the market economy system.
Hebei has only met water demand through overdraft of deep groundwater, resulting in the formation of a groundwater overdraft depression. This issue is further exacerbated by saline water intrusion into the groundwater tables. The water administrative department has taken measures accounting for IWRM principles, for example by establishing the Water Users Association to encourage participatory management. The lesson learnt is the value of a participatory approach in management.
Guizhou already experiences the effects of climate change, including droughts. Action was taken with the approval of a new policy document which provides funds supporting water quality improvements, water and soil conservation, ecosystem rehabilitation, irrigation, and managing increasing demand. Steps have also been taken for preventive actions for subsequent droughts. The most important lesson that can be learnt is that the greatest challenge to building resilience to droughts is institutional.
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.
Water Supply and Sanitation policy in Vietnam is regulated through policy and a regulatory framework. However, the rural sanitation sector have had limited success and management has failed to be scaled up. To address these issues the Problem-Driven Governance and Political Economy Analysis Good Practice Framework was used to analyse the poor performance. The most important lesson is that not all policies are appropriate for scaling up.
Half of the land area of Tien Giang Province in Vietnam is exposed to annual floods and the other half to saline intrusion. Action was taken to formulate the National RWSS Strategy and efforts were made to make local communities aware of methods and approaches in harvesting water and well drilling that are cost effective and sustainable in their development. The key lesson is the value of appropriate planning prior to any project.
There are growing concerns about the potential effects of climate change on the socio-economic characteristics and natural resources of the Lower Mekong Basin. In response to the potential impacts of climate change, the Mekong River Commission has launched the regional Climate Change and Adaptation Initiative. Furthermore, a Vulnerability and Adaptation Assessment has been conducted. The most important lesson learnt is that it is essential to establish a regional organisation to combat climate change.
The most pressing problem facing the Songkhla Lake Basin is land degradation and water pollution caused by land use changes and shrimp farming expansion. Action was taken to combat these issues and an Integrated Environmental Management approach was applied. The key lesson of this case is that replacing blueprint master planning approaches with process oriented planning frameworks increased sustainability significantly.
To increase agricultural productivity, the Ministry of Agriculture and Irrigation has encouraged many farmers to organise water users groups. Yields are to be increased through the collaborative and efficient participation of beneficiary farmers engaged in irrigation. This has led to efficient water distribution throughout the managed watercourse. The most important lesson learnt is the importance of the strengthening of each water user group.
Clearing for logging, combined with expanding agriculture and palm oil plantations has led to increased flooding, and pollution of the Kinabatangan River due to pesticides and fertilizers. Working in partnership, the Sabah Wildlife Department and the WWF took action and have established the Lower Kinabatangan Wildlife Sanctuary. The key lesson of this case is the value of starting with small-scale feasible projects before scaling up.
