Oil-shale mining and oil-shale based electricity production has caused serious damage to ground and surface water in the Viru-Peipsi catchment area in Estonia. Action was taken to enhance the protection of the water resources through a project that set out a management plan. The project included data collection, monitoring and capacity building. Due to the success of this project, it can be used as an example for future developments.
The Tsurumi River Basin, located in the suburbs of Tokyo, extends over an area of 235 km2 and a river length of 42.5km. The Tsurumi River Basin is regarded as one of the most important and representative river basins in Japan. The basin was largely developed by the rapid urbanization since the 1960s.
Activities such as horticulture and tourism around the Great Barrier Reef create sediment, nutrient and pesticide runoff, placing increased pressure on the ecosystem. The World Wildlife Fund has taken action, predominantly by raising awareness. The key lesson is how a carefully orchestrated campaign can convince decision-makers of the importance of integrated river basin management as a means of reducing land-based marine pollution.
Rapid urbanisation has led to widespread settlements of floodplains, resulting in widespread vulnerability of livelihoods. Since traditional approaches are no longer sufficient, a more integrated flood management approach was realised to adapt to changing social, hydrological, and environmental conditions along the nation’s major waterways. Furthermore, the Ministry of Water Resources prepared a national flood management strategy. The crucial lesson is that the key to flood risk management is learning to live with flood risks.
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.
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.
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.
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.
