Main Issues on Water and Climate Change Adaptation in

strategies, and programs for climate change adaptation.

Less funding, expertise and technology for climate change.

Lack of people awareness and involvement for climate change

adaptation.

Ongoing / Planned Water and Climate Change

Ada tation Initiatives in the Brantas River Basin

Adaptation of Climate Change Impact on Flood

Improve management and maintenance of existing flood control

systems

Rehabilitation of damaged flood control structures

Develop telemetering system using GSM network for rainfallmonitoring

Promote watershed conservation

Non Structural

Flood planing zoning (structuring flood plain and flood area zoning).

Flood Forecasting and Warning System Promote people centre early warning system

Public Education : 1) Formal - public school curriculum and 2) Non-formal (disseminate disaster risk reduction and strengthen capacity

trough training to youth center) Prepare disaster legislation, regulations and standard operating

procedures.

Ongoing / Planned Water and Climate Change

Ada tation Initiatives in the Brantas River Basin

Adaptation of Climate Change Impact on Drought

Promote water supply (availability) and demand management

Supply side

Removin sediment from reservoirs for more stora e

Propose increasing storage capacity by heightening and buildingreservoirs and dams

Optimize reservoir operation

Rainwater harvesting

Use conjunctive surface/groundwater supply

Demand side Increase water use and irrigation efficiency (Develop System of Rice

Intensification (SRI), develop insentif system, etc)

Propose reduction in water demand for irrigation by changing the, , ,

Encourage industry to recycle water

Expectations from the Regional Knowledge Hub

NAHRIM and its Network

 A. Climate change project ions

Share information on planned and ongoing climate change adaptation

activities in Southeast Asia countries and in other developing and developedcountries.

B. Impact assessments

Help RBOs to assess the impacts of global climate change and land use

interactive climate, hydrology and water quality models.

.Help RBOs to develop appropriate policies for the management of the waterresources of the region in basin level in mitigating potential impacts ofclimate changes.

Proposed collaboration with NAHRIM

Collect data and observations related to weather and climate inBrantas River basin.

Conduct climate modelling, scenarios and downscaling in basinlevel.

Pilot adaptation models at local level, and integrate with localdevelopment process.

Conclusions

Climate change will have wide-ranging impacts on the environment,

soco-economc an reate sectors nc u ng water resources,

especially in developing countries because they have fewer resourcesto ada t sociall , technolo icall and financiall . As ha ened in late

December 2007 and early January 2008 in Bengawan Solo and

Brantas River basins, where severe flooding and landslides occurred.

Assistances from international parties in forms of capacity-building,

transfer of technology and funds to support monitoring and forecast of weather and climate, as well as advance flood forecastin and warnin

systemin the basins are needed as measures to adapt climate change

. ,

capacity-building are also needed to reduce the risk of disasters and

raise the resilience of communities to increasing floods. 8
