WHAT IS CLIMATE?WHAT IS CLIMATE?The weather condition prevailing in an area in

general or over a longer period.

WHAT IS CLIMATE CHANGE??WHAT IS CLIMATE CHANGE??Climate change refers to a change in the state of the climate that can be identified by changes in the mean and/or variability of its properties, that persists an extended period,typically decade or

longer. (IPCC,2007)

PROFILE OF COASTAL ZONES

Important & critical region for India,endowed with a coastline of over 7500km.3 out of 4 major cities are located in the coastal regions. (Mumbai,kolkata,Chennai)Total area occupied by the coastal districts :379610sqkm.Average population density of coastal area is 1.5times of national average

VULNERABILITYVULNERABILITY Vulnerability is the degree to which a system will

respond to a given change in climate,including beneficial & harmful effects.It is also a function of the character,magnitude,and rate of climate change & variation to which a system is exposed its sensitivity and adaptive capacity.According to IPCC,the extent to which climate change may damage or harm a systemIt has 2 elements.

a)the severity of the impact of the shock b)a person's resilience to a given shock [resilience is the indicator of adaptive capacity]

INDIA'S VULNERABILITYINDIA'S VULNERABILITYVulnerability of coastal zones to climate change related natural hazards are:-(a)sea level rise

(b)tropical cyclones

(c)temperature & precipitation changes

Vulnerability to climate change is influenced by: >ongoing social & economic shocks >rapid population growth >urbanization >industrialization

DOUBLE EXPOSUREDOUBLE EXPOSUREConcept of DOUBLE EXPOSURE indicates that

the climate change and globalization are occuring simultaneously.

Regions,sectors,ecosystems and social groups will be confronted by both the impacts of climate

change and consequences of globalization

IPCC vulnerability framework:

V= f(E,S,AC) E=exposure , S=sensitivity ,

AC=adaptive capacity

EXPOSUREEXPOSUREThe degree of climate stress upon a particular unit

of analysis. Climate stress: a)longterm climate condition b)climate variability c)magnitude and frequency of extreme

events

SENSITIVITYSENSITIVITY

The degree to which a system will respond Either positively or negatively

To change in climate

ADAPTIVE CAPACITYADAPTIVE CAPACITYCapability to adapt

ADAPTATION—adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects.

SOCIO-ECONOMIC IMPACTSSOCIO-ECONOMIC IMPACTSClimate change will slow down the economic growth of a region as well as the establishment of healthy society It will lower the incomes Of vulnerable populations and increase the absolute number of people at risk of hunger,poverty and even survivalEven small scale increase in temperature will prompt food prices as its impact is remarkable in agriculture
