Goals of training

An approach and methods needs to increase our
understanding of the issue of climate variability, climate
change and health assessment.

A general discussion on the potential impacts of climate
variability and change on health sector in the region.

A general discussion about of steps in a vulnerability and
adaptation assessment.

Provides concepts and examples of coping and adaptive
capacity in the region.

A general discussion about the data, tools and methods
available to assess V&A in the health sector by means of
a case of study.
Human health vulnerability to climate can
be defined as a function of :



Sensitivity, which includes the extent to health, or the
natural or social systems on which health outcomes
depend of sensitive to changes in weather and climate
(the exposure–response relationship) the characteristics
of the population, such as its demographic structure.
The exposure the climate-related hazard, including the
character, magnitude, and rate of climate variation.
The adaptation measures and actions in place to
reduce the burden of a specific adverse health outcome
(the adaptation baseline), the effectiveness of which may
influence the exposure–response relationship.

Steps in the Vulnerability and Adaptation
Assessment in health sector (Kovasts et, al 2003)

Step 1.

Step 2. Describe the current distribution and burden of climatesensitive diseases.





Determine the scope of the assessment.
Step 3. Identify and describe current strategies, policies and
measures which reduce the burden of climate-sensitive
diseases.
Step 4. Review the health implications of the potential impact of
climate variability and change in other sectors.
Step 5. Estimate the potential health impact using scenarios of
future climate change, population growth and other factors for
describe the uncertainties.
Step 6. Synthesize the results and draft a scientific assessment
report.
Step 7. Identify additional adaptation policies and measures to
reduce potential negative health effects, including procedures
for evaluation after implementation.
Step 1: Include to Identify Indicators in
Sectors and Examine Current Conditions.

Key sectors
– Solicit or survey local decision-makers and stakeholders
– Is appropriate rank or set priorities according to climate
sensitivity and importance
– Define baseline conditions using current data related to
sectors and indicators
Step 1:
(cont’d)
Some Indicators of impacts






Increased disease incidence
Increased disease prevalence
New records of disease
Severe forms of diseases
Increased case fatality rate
Cases exceed medical capacity
Demography

population, age structure, migration index
Step 2: Include to description the current
burden and recent trend in the incidence
and prevalence of climate-sensitive health
determinant and
develop Baseline
Scenarios (without climate change)
Examine recent trends and seasonal variation and
the relationship climate variables, including:


Identification the signal climate in the patterns diseases.
To analyze association with exposure to weather or climate
variability.
Step 3: Include the key aspects to
address for specific health outcome
The specifics questions include the following:



What is being done now to reduce the burden of disease?. How
effective are these policies and measures?
What could be done now to reduce current vulnerability?. What
are the main barriers to implementation (such as technology or
political will)?
What options should begin implemented to increase the range of
possible future interventions
Step 4: Include the results of other
assessments should be includes to
better understand.
Sectors such as:

Agriculture and food supply, water resources, disasters on coastal
and river flooding.

Review the feedback from changes in population health status in
these sectors.
Step 5: Requires the generation and
using climate scenarios. Climate
scenarios are now available for a range
of time scales.
Examine different


:
Models of climate change should include projections as other
relevant factors may change in the future, such as population
growth, and other relevant factors.
The potential future impact of climate variability and change on
health may be estimated using a variety of methods.
Step 6:
This step synthesizes the quantitative
and qualitative information collected in the
previous steps.
Includes :



to identify changes in risk patterns and opportunities.
to identify links between sectors, vulnerable groups and
stakeholder responses.
Convening an interdisciplinary panel of experts with relevant
expertise is one approach to developing a consensus assessment.
Step 7: Identify possible adaptation measures that
could be undertaken over the short and long term.
Goals of this step


To increase the capacity of individuals communities and
countries to effectively cope with the weather exposure of
concern.
To identify possible measures can be taken today and in the
future to increase the ability of individuals communities, and
institutions to effectively cope with future climate exposure.

Main Climate Trends Observed in Cuba During the 1990s

Increase in mean environmental air temperature, primarily
due to increases in minimum temperature

Decrease in diurnal variation temperature (Oscillation)

Increase in precipitation in the dry season and decrease in
the wet season

Later start of the wet and dry seasons, and a lag in the
summer precipitation

Increase in extreme weather events: e.g. droughts, floods,
and other dangerous meteorological events

Stronger hurricane seasons

More frequent extreme temperature events [warm events
(1991-1993, 1994-1995, 1997-1998, 2002-2003) and cold
events (1994, 1996, 1998-1999, 1999-2000)]
Research in multiples scale and data in Health Sector



Research: Is need to conduct community based
assessments and systematic research on the issues of
climate change impacts in our countries and in all region.
Multiples Scale: Local, regional and national scales are
interconnected in supporting and facilitating action on
climate change, is need for data at multiple scales and
research that links scales to understand these relationships.
The Data: Innovative approaches to health and climate
assessment are needed and should consider the role of
socio-cultural diversity present among countries. This
requires both qualitative and quantitative data, and the
collection of long term data sets on standard health
outcomes at comparable temporal and spatial scales. They
favor the development appropriate applications for the
sector health.
How are the relationships between variability and climate change
and epidemiological pattern changes?

Methods
Research methods used so far include
predictive modelling, analogue methods and
early effects.
Predictive models include
biological models (e,g malaria), empirical
statistical models (e.g, temperature-mortality
relationships), the used the complex index
simulation variability climate change and other
processes (e.g, relationship climate index and
diseases) and integrated assessment (IA)
models. Is need the balance empirical analysis
with scenario-based methods and to integrate
the different methods through, for example, IA
methods. The outcome of an assessment may
not necessarily be quantitative for to be useful
to stakeholders.

Case Study: Cuba
Indicators used in the study
Global Data:
For each month include three variables.
Multivariate ENSO Index, (MEI) Quasi-Biennial
Oscillation,
(QBO)
and
North
Atlantic
Oscillation, (NAO) values available prior to 1950
of Climate Diagnostic Center (CDC). These
indices can be considered as an expression of
the forcing of the interannual, decadal variability
in the studies region.
Epidemiological data:
Thesis base include the indicator of the number of
cases the: acute respiratory infections (ARIs),
acute diarrhoeal disease (ADDs), viral hepatitis
(VH), varicella (V), meningococcal disease (MD)
and malaria borne Plasmodium falciparum and
Plasmodium vivax.
Ecological data:
Climatic data.
These base include series of monthly from
maximum and minimum temperature in 0C,(XT,
NT) precipitation in mm, (PP) atmospheric
pressure in hPa, (AP) water vapor pressure in mm
of Hg, (VP) relative humidity in %, (RH) thermal
oscillation, (TO) day with precipitation, (DP) solar
radiation in MJ/m2, (SL) and insolation in HL, (I)
were available for 51 stations in all country. For
the period 1961-1990 that constitute baseline
climate, and 1991 to 2003 is used for the
evaluated to conditional actuality.
The base date ecological includes the following
indicators: Larval density (LD) and biting density
hour (BDH), as indicative entomological we use
the number of positive houses (NPH).
Socio-economic data:
In this case used variables such as % of
residences without potable water (PHD); % of
residences with soil floors (PHF); illiteracy rate
(IR); monthly births (MB); and index of monthly
infestation (IMI).
To define climate characteristics and its health effects in Cuba,
a complex approach has been developed

Temperatures
•Daily Oscillation Temperatures
•Relative Humidity
•Vapor pressure
•Atmospheric pressure
•Rainfall
•ENSO influence (MEI)

Some examples of adaptation measures to climate
variability and change in Cuba. (Ortíz, el al 2006)
Options of adaptation
Current activities
Future activities
To strengthen primary
health care of the public
health system.
Health promotion and preventive
activities in health by means of
specific programs reduce the
population vulnerability. Education
programs according to environment
risks
including
change
and
variability of the climate and theirs
effects on human health. Increase
the use of vaccines against some
community diseases.
To continue developing the
programs of Health promotion
and
preventive
programs
increasing
the
community
participation on health.
Increasing the participation of the
local governments and others
sectors in developing the best
conditions of life in order to
guarantee the sustainability of
human health.
Measures to improve the
surveillance system in
health.
To maintain the forecast of the main
communities diseases with a good
information at all levels of the
National Public Health System
Increasing an early warning system
to predict epidemics.
To continue developing researches
in order to improve the forecast
models
using
the
indexes
necessary to obtain the best
results.
Incorporating new diseases and
risk factor in the forecasting
models.
To improve the statistics of the
climatic, epidemic, ecological and
social variables that allows
diminishing
the
levels
of
uncertainty in the projections
adaptation measures ( Cont)
Immunization program
for the groups of high
risk and all population.
To maintain the current program of
vaccination and to priorities new programs
directed to the varicella (chicken pox) among
other important diseases.
Influenza vaccination program in ancient
applies using Influenza vaccines against the
agents circulating and before the peak of
Acute Respiratory Infections. Besides, to
continue the immunization program against
Haemophilus influenzae to achieve their
successful control; and to maintain
antimeningococcal immunization program.
In the future is necessary to carry out a
prevention program against Chicken pox
previous the forecasting increase.
Improvement of
sanitary conditions.
the
Increase of sanitary demands in all fields
(communal, drinking water , garbage,
sewage, foods and others)
Maintain contingency plans
Educational programs about environment care
with the participation of the community,
governments, and all sectors. Increase of
environment care projects. To improve
contingency plans.
Educational programs in
TV, in radio, news papers
and others.
Maintain the forecast of
the behavior of a group
of
communicable
diseases through IPK–
Epidemiological bulletin.
To expose results of the climate and health
researches that allow the best understanding
of the concepts, work methods and achieved
advances to settle down that contribute to a
risk perception to the variability climatic and
change and their impact on human health .
Distribution of the IPK – Bulletin at all of the
levels of the National Public Health System.
Implementation of new programs about
climate-health using all the way of
communication to population, governments
and others.
Exchange
information
with
scientific
and
researches working in
this task in the world.
To participate in international meetings,
congress, and others.
Looking for new projects with participation
with other countries.
To do the forecast for each province and
municipalities level.

Conclusion

These section show that human health is an integrating theme of climate
variability and change. Population health is affected by climate and
particularly by climatic effects acting through natural disasters, climatesensitive diseases and through climate-sensitive sectors such as agriculture,
water, or human environmental.

In the Latin American and Caribbean region, increasing understanding of
the potential health impacts of climate variability and change, identifying as
those vulnerable to variability and long-term climate change (cyclones,
floods, and droughts) in Small Island.

Health is therefore both a key climate-sensitive sector in its own right, and
also provides an important justification for addressing climatic impacts on
other sectors .

The main roles for climate information in operational health decisions are:
1) Identification of climatically suitable or high-risk areas for particular
diseases
2) Early Warning Systems for climate-sensitive diseases can vary over time.
Conclusion. (cont’d)

These results demonstrate the studies of climate and health is necessary to
increase our knowledge of the effects of climate on human health; such
information is important for decision-makers for reducing the economicsocial impacts of climate variability and change in the region.

This study is innovative in the development of complex climate indices to
reflect climate anomalies at different scales, and to explain the mechanisms
and relationships between climatic conditions and diseases.

Based on our experience with the studies in Vulnerability and Adaptation
Assessment, it is clear that the climate prediction can be used to prepare
from climate variability and extreme events for the Climate Change,
including an estimation of costs.

Our experience also demonstrates that interdisciplinary collaboration and
the sharing of information, experience, and research methods among
sectors are critical for effective policy formulation and the development of
support tools for decision-makers.

The results of this study evidence a clear non lineal relationship between
the changes of the climatic variations and the changes of the patterns of
behavior of both diseases in a differentiated way
