Knowledge sharing versus climate change.
A resource for effects mitigation in Malika, Senegal
involvers- the relationship of the local authorities , the private
sector and the civil society
Complementation- autonomous and planned adaptation
Experimental process- building adaptive capacities,
knowledge sharing and delivering adaptations
Case study Malika, a peri-urban area of Dakar
sub- Saharan African territories in which the increased in
flood since 2005 are undermining citizens daily life and
agricultural activities.

Autonomous adaptive capacity to environmental change in
peri-urban Dar es Salaam
Problem- In Dars peri-urban area , the dependence on
natural resource make them vulnerable to environmental
changes
the crucial factors in adaptive capacity at local level- the
livelihood strategies, autonomous adaptation and
environmental management practice
Methods- the field work
Solution- a need for understanding and multiple adaptation
strategies in local level and he informing decision making
process

Vulnerability = Exposure + Sensitivity Adaptive capacity
V = E + S - A
Vulnerability is the degree to which a system issusceptible to and unable to cope with adverseeffects of climate change
Adaptive capacity(focus): the capability to modify exposure to risks
associated with climate change , absorb and recover from losses
stemming from climate impacts and exploit new opportunities that
arise in the process of adaptation.
Exposure : The character, magnitude and rate of climate change
and variation to which a system is exposed to.

NGEMA project- neighborhood growth and
environmental management in Dar es Salaam, Tanzania
Project introduction
preliminary design of an urban area of approximate10000 people
Site: Des Temeke municipality in Des. Lower urban development :a colossal project - a new settle- Kigamboni - a pure visionary
project
NGEMA priority objective -
Sustain the agriculture( US) as a model for a sustainable economic and environmental
growth of the cityProvide basic urban infrastructure
Create a multi-fuctional
Integrate commercial and integrate commercial are residential space
Sustainable buildings and renewable energy

Vulnerability to Flood in Maputo, Mozambique
ProblemOn the 15th of January 2011 a rainfall of 200mm
devastated Maputo
Risk assessment developed by M.Tiepolo for Agriconsulting
with UNHC&CCI
R = (H X V X E)/ A
R- riskH- hazard
V- exposure
A- adaptation
NoteField visits are to identify vulnerability since the minor altimetry variations
may be invisible in DEM analysis or topographic maps.
A cross check with after rain on- field inspection is essential.
1 Poverty
2 The rate of land
covered by roofs
and tree canopy
3 The soil type
4The watershed size

Adaptation to climate change in Maputo, Mozambique
Study goal
identify ongoing measures in Maputo Municipality
Define, prioritize and timing future measures
R = (H X V X E)/ A
A panel of 33 adaptation measures in 8 most flood zoon and
3 main area prone to see level rise
8 interviews after field visit conducted by technicians andbairro secretary general
A group discussion between 6 municipal environment
department employees to defined the importance of the
measurements and to gather opinion on future measuresusing 5 predefined criteria for judgment

Reducing the vulnerability of unban contexts in the
rural Mozambique through spatial planning
African rural towns are
instable due to exogenous
factor (civil war
globalization of theeconomies and CC.
Hybrid settlement pattern
agriculture
essential urban characters

Linking vulnerability, resilience and change:
a study in Caia district, Mozambique
The emergencies are multi-faceted and the result is not ofphysical events alone
Address the social- cultural andenvironmental consequences ofloss of the land in Caia.
The result shows that is current
policy is not addressing the realcause of poverty and access tonatural resources as priority.

Early warning practices in a climate change
The global upward trend in natural disasters occurrence, in
particular hydro meteorological ones
In the early warning for flooding, 2 instruments are
presented:ERDS- extreme rainfall detection system, based on the
analysis of historical rainfall values derived from TRMM dada
provide vulnerability maps derived from the analysis of time
series of MODIS data A system based on satellite vegetation indices for the
monitoring the drought induced vegetation stress.
