Vulnerability concerns the risk of adverse things happening. Climate change is likely to have some benefits, but vulnerability is not concerned with that.
The sustainable livelihoods approach focuses on livelihoods of the poor. It focuses on the assets and vulnerabilities of the poor. It is an approach for identifying development needs and for assessing the effectiveness of existing poverty reduction programs. The focus is very much on the current situation, i.e., near-term planning rather than long-term planning. The challenge in using approaches such as this to examine climate change is how to reconcile a focus on the short term with long-term climate change.

VULNERABILITY AND ADAPTATION - Presentation Transcript
VULNERABILITY AND ADAPTATION Reference notes from UNFCCC & IPCC Resource material - Dr. N. Sai Bhaskar Reddy CEO, GEO http://www.e-geo.org
Vulnerability
Vulnerability to climate change is the risk of adverse things happening
Vulnerability is a function of three factors:
Exposure
Sensitivity
Adaptive capacity
Adaptation
“ adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm of exploits beneficial opportunities” (Third Assessment Report, Working Group II)
Notice includes “actual” (realized) or “expected” (future) changes in climate
Adaptation (continued)
Two types of adaptation:
Autonomous adaptation or reactive adaptation tends to be what people and systems do as impacts of climate change become apparent
Anticipatory or proactive adaptation are measures taken to reduce potential risks of future climate change
Sustainable Livelihoods
Scenarios
Estimation of future agricultural responses to climate change is usually based on scenarios.
The scenarios are essential for evaluating possible future (?) conditions, but they do not necessarily describe the conditions that will actually occur.
They should be used to explore possible adaptive measures.
Biophysical impact
Changes in crop growth conditions
Changes in optimal conditions for livestock production
Changes in precipitation and the availability of water resources
Changes in agricultural pests
Changes in soil fertility and erosion
The combination of biophysical and socio-economic effects can result in:
Changes in the mix of crops grown, and hence in the type of farming and rural land use
Changes in production, farm income, and rural employment
Changes in rural income, contribution to national GDP, and agricultural export earnings.
Household and village models
(Semi-commercial economies)
to secure a minimum level of income
strategies developed to reduce the negative effects of crop yield changes or coping strategies like during drought
As with farm models - borrow from existing studies, adapting them to consider changes in climate rather than variations in weather.
Scaling up the vulnerability and adaptation results to regional level :
Regional assessments =>
+ input provided by regional planners and economists
+ local data
+ discussions with a full range of stakeholders
Farm-based adaptation measures
Choice of crop
Use of drought or heat resistant varieties, Use of pest resistant varieties, Use of quicker (or slower) maturing varietiesAltering mix of crops
Tillage and time of operations
Change planting dateTerracing, ridging, Land levelling, Reduced tillage, Deep ploughing, Change fallow and mulching practices, Alter cultivations, Switch seasons for cropping
Farm-based adaptation measures
Crop husbandry
Alter row and plant spacing, Intercropping,
Irrigation and water harvesting
Introduce new irrigation schemes to dryland areas, Improve irrigation efficiency, Water harvesting,
Input of agrochemicals
Vary amounts of fertilizer application, Alter time of application, Vary amount of chemical control
