National Communications
Under Articles 4.1 and 12.1 Parties should develop and publish their national communications.
Under the new guidelines (decision 17/CP.8), Parties should communicate to the COP a general description of programs containing measures to facilitate adequate adaptation, etc.
Reporting Requirements
The following categories of impacts/vulnerability are expected to be reported: agriculture, tourism, health, forests, water resources, infrastructure, rangeland, coastal regions, ecosystems and biodiversity, wildlife, fisheries and the economy.
Vulnerability Assessment and Adaptation
Vulnerability is a function of the character, magnitude and rate of climate change and variation, to which a system is exposed, its sensitivity and its adaptive capacity [Summary for Policy Makers (IPCC WG II)]
Adaptive capacity is the ability of a system to adjust to climate change (including climate variability and extremes) to moderate potential damages, to take advantage of opportunities or to cope with the consequences [Summary for Policy Makers (IPCC WG II]
After vulnerability and adaptation analyses- What’s next?
The interest should now be on incorporating initiatives, measures, strategies to reduce vulnerability to climate change into other, existing policies, programs, resource management structures, disaster preparedness program, livelihood enhancement activities, and other sustainable development initiatives.
WHY?
It is unrealistic to expect special policy initiatives to deal with climate change adaptation by itself, especially when so many of the suggested adaptations (drought planning, coastal infrastructure planning, flood preparedness, early warning, livelihood enhancement, etc) were being addressed in other policies or programs.
Why is Integration Important?
Impacts do not happen in isolation Impacts in one sector can adversely or positively affect
another Some sectors are affected directly and indirectly Others just indirectly Sometimes a change in one sector can offset the affect
of climate change in another sector In addition, integration is necessary for ranking
vulnerabilities and adaptations
Main Types of Integration of Results
Cross-sector integration Link related sectors
Multisector Economy or system wide
Integrated assessment models Economic models
Some Integrated Assessment Models

Impacts in One Sector Can Overwhelm Direct Climate Effect
In a recent study, crop yields in California were generally estimated to increase with climate changeIn one scenario, a 25% reduction in water supply results in a net loss of $1 billion/year to California agriculture

Multi-sector Integration Modeling
IMAGE Model
Regional/National Economic Models
Quantitative way to examine climate change market impacts throughout an economy Problem with non-market impacts
Often macroeconomic models or general equilibrium models
Require much data Can be expensive Can be complex Communication of assumptions can be a
challenge
An Example of a Regional Model
A More “Simple” Approach
Add up results sector by sector Limited by what is known within sectors Problem of how to integrate across multiple
end points Impacts may be measured with different
metrics Need to account for many sectors Does not capture sectoral interactions
Estimates of Damages for India
Sector Damages ($ billions)
Agriculture -53.2
Forestry +0.1
Energy -21.9
Water -$1.2
Coastal Resources -$1.2
Can Also Measure Number of People Affected
“Millions at Risk” study did this Global burden of disease
Millions at Risk Study
At a Minimum
Should at least qualitatively identify linkages and possible direction of impacts
If crops can be examined, not water supply, then identify how change in water supply could affect agricultural production
Integration through Setting Priorities
Vulnerability Adaptation
Prioritization of Vulnerabilities
It can be quite useful for Focusing adaptation measures Monitoring Adaptation
Examples of Adaptation Integration
Caribbean (CPACC, GEF/WORLD BANK, CIDA) Integration of adaptation into national policies dealing with
risk management and into their Environment Impact Assessment procedures.
Mozambique (World Bank) Integrating Adaptation to climate change risks into Action
Plan for Poverty Reduction
Bangladesh (CARE-CIDA) Climate change adaptation is mainstreamed into
sustainable development planning
Example of Adaptation Integration
China (ADB, World Bank) helping poor farmers adapt to drought
conditions- government undertook integrated ecosystems management-house-level eco-farming integrated renewable energy such as solar power, vineyard cultivation and legume planting for fixing sand and providing forage.
Process is as Important as Outcome
This is an expression of values, not a purely analytic exercise
Need to include stakeholders and policy makers
The following are tools that can be useful in setting priorities
Whether you use qualitative or quantitative approach, the most important thing is JUST DO IT

Benefit-Cost Analysis
Estimate all benefits and costs in a common metric to determine whether benefits > costs
Monetary values often used Difficulty: what to do about non-market
benefits or uncertainties Difficulty: requires much data and analysis
BCA Example: Sea Walls in Kiribati
What to Use
Conclusions
Integration is important to at least identify related impacts Analysis is desirable because there can be
surprises Integration can also be useful for examining
total vulnerability and ranking vulnerabilities
Conclusions
There should be involvement of local stakeholders, the private sector, individuals, the research community and different levels of government.
Awareness raising and capacity building also essential.
