The Bodrog River Basin is exposed to severe flooding caused by jumbled urbanisation and low connectivity between land (agriculture and forestry), urban and water planning. Management is made more complex by the transboundary nature of the basin. A project was, however initiated to strengthen cooperative management and to mitigate consequences of floods through achieving consistent and holistic management of flood risk in three basin countries. This case illustrates the importance of transboundary flood management.
The Tisza River is faced with deteriorating water quality as well as floods with increasing frequency and levels. These issues are exacerbated by climate change. Action has been taken, both by national authorities, international actors and NGOs to develop more adaptive management schemes. The key lesson is that in water management, the biggest problem is the weak coordination among different fields and interests – such as agriculture, nature, navigation, flood defence.
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.
After some devastating floods in the Yangtze, the Chinese government took action and issued a policy to counter floods, including wetland restoration. WWF further assisted and developed four pilot sites to demonstrate the benefits of wetland restoration for biodiversity, and to seek alternative income options for farmers, based on the sustainable use of wetlands. This case illustrates the value of a participatory approach.
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.
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.
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.
The Pantanoso watershed in Montevideo has been identified as vulnerable to threats of intense rains and floods, posing risks to the human settlements. To combat the risks, action was taken by the local population and governmental authorities to engage in a project on Climate Related Disaster Risk Management. The key lesson is that strengthening vulnerable communities upon climate risks represents a key tool for the IWRM, since it contributes to empowering the population.
The Cuero River area is particularly susceptible to floods, making the communities living in the surrounding area vulnerable. This area was consequently chosen for implementation of an Early Warning System Project. Action was taken in three separate phases in three different areas. From the experience, the lesson learnt is that more effort should be devoted to training of a leader group that can promote and consolidate the system’s self-sufficiency.
The Senegal River has seen considerable migration of people in view of worsening drought and desertification. Furthermore, it is subjected to threats such as loss of arable land, and pollution from waste. To address the problems and to realise the potential of the basin, the Senegal River Development Organisation was established by three of the riparian states. This case gives important insights into how an institutional and legal infrastructure can be built in stages.
