Water Resources Management
Entry points for Adaptations
• Planning new investments, or for capacity expansion
(reservoirs, irrigation systems, levees, water supply,
wastewater treatment)
• Operation & regulation of existing systems: accommodating
new uses or conditions (e.g. ecology, climate change,
population growth)
• Maintenance and major rehabilitation of existing systems
(e.g. dams, barrages, irrigation systems, canals, pumps, etc.)
•Modifications in processes and demands (water conservation,
pricing, regulation, legislation)
•Introduce new efficient technologies (desalting,
biotechnology, drip irrigation, wastewater reuse, recycling,
solar energy )

Adaptations in Water Resources Management
Guiding Principles
• Mainstreaming climate change adaptation within broader
development context
• Strengthening water governance and integration of land
anndwat management
• Improving and sharing of knowledge and information on
adaptation measures and invest in monitoring
• Building long-term resilience through stronger institutions,
invest in infrastructure and well functioning ecosystems
• Invest in cost effective and adaptive water management as
well as technology transfer
• Leverage additional funds through national budgetary and
innovative funding mechanisms

Basic Messages
• All drivers of hydrological cycle are affected by global
warming – climate change (CC)
• Water is the principal medium through which most
people will experience CC
• Many tools, coping options designed for Climate
Variability (CV), form the foundations for CC adaptation
• Socioeconomic factors, land uses, conflicts and
population dynamics will dominate future conditions
and modes of adaptation
• Huge upfront investments to avoid highly uncertain CC
risks have to be dealt with in a well-organized risk
management framework

Basic Messages
• Keystone for adaptation and adaptive management is a
greatly expanded and improved hydromet system for
monitoring, modeling and forecasting
• Climate information, GCMs and prediction services
need to be dramatically improved
• Improving governance is key to CC adaptation
• Therefore, CC adaptation must be cast within a
broader IWRM framework, and not viewed as an
independently pursued analytical paradigm

GFCS Goal
Enable better management of the risks of climate variability
and change at all levels, through development and
incorporation of science-based climate information and
prediction into planning, policy and practice.”

GFCS: Objectives
• Provide a cooperative framework in which all nations,
International organizations, scientists and sectors will
work together to meet the needs of users;
• Enable users to benefit from improved climate information
and prediction;
• Mobilize climate science globally to advance the skills of
seasonal-to-interannual and multi-decadal climate
predictions to generate and provide future climate
information on an operational basis;
• Foster mechanisms for sharing new advances in science
and information through a cooperative global
infrastructure.
