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.
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.
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.
To improve the state of the Balikpapan Bay coastal ecosystem, a coastal zone management project was initiated. After initial project failure, action was taken for policy reform and an adaptive management approach was developed, focusing on inter-agency integration. This case illustrates the importance of active project learning and adaptive management.
The city of Jabalpur experienced water shortages. Action was taken through a scheme, which would augment the water supply to the city, by substantially increasing funding. The key lesson is how an empowered local body can respond to water challenges in a successful manner.
The city of Bhopal in Madhya Pradesh is mainly receiving its water from Upper Lake. However, in the past decades, the water quality has steadily been deteriorating. This has led the government to take action and implement an integrated lake conservation program. The case demonstrates that all the stakeholders, especially, Urban Local Bodies and the public representatives should be involved in the decision making from the very beginning of such projects.
Due to substantial population growth putting increased pressure on the water resources, their quality has started to deteriorate. This is perceived as a serious issue since water is inseparably linked with the socio, economical and cultural aspects of livelihoods. Action was taken through an integrated lake conservation programme, aiming to improve water quality. The most important lesson learnt is that awareness raising, education and stakeholder participation are essential.
