1. Disasters and disaster trendsDisaster impacts are generally increasing as a result of the combination of increasing populations, greaterconcentrations of people and assets in vulnerable areas, greater use of insurance and the modification anddegradation of natural environments, such as floodplain settlement, coastal exploitation, wetlanddestruction, river channelling, deforestation, soil erosion and fertility decline. Vulnerability to hazards isexacerbated by poverty, disease, conflict and population displacement
The context of natural hazards in the continuum of human experience
Disaster to includes– death toll;– traumatized population (through injury, homelessness, loss of livelihoods);– environmental and economic impacts that overwhelmed the coping capacity of the affected people)D. Bashir & M. Garba 8
Disaster is a serious disruption of the functioning of a community or a society causing widespread human, material, econom ic and/or environmental losses which exceeds the ability of the affected community or society to cope using its own resources (UN- ISDR, 2002)
Why is climate change adaptation needed? • Climate changing is undermining the sustainability of livelihoods. • Climate change is overwhelming the natural resources on which livelihoods depend. • Climate change is increasing climate-related disaster risk.Photo: Shehab Uddin/DRIK/Oxfam GB
Who are most vulnerable and why?• Those who depend on climate-sensitive resources and ecosystems for their livelihoods; agriculture, fisheries, forests.• Those who live in marginalised and hazard prone areas; deforested hillsides, flood plains, urban slums.• Those with limited assets and political voice to enable them to respond to the impacts of climate change; low adaptive capacity.
Factors Affecting Disaster Impacts• Impacts of disasters are exacerbated by a number of factors that include: – poor land-use planning, – population growth, – environmental mismanagement, – increasing levels of vulnerability, – poor planning, – poor governance, – climate change, – lack of regulatory mechanisms, & – corruption
Impacts of Climate Change• Water related hazards are likely to get worse in this century due to climate change• IPCC estimated the impact of global warming and predicted that: – "Drought-affected areas will likely increase in extent; – Heavy precipitation events, which are very likely to increase in frequency, will augment flood risk."

VulnerabilityVulnerability to climate change is the risk of adverse things happeningVulnerability is a function of three factors: Exposure Sensitivity Adaptive capacity
Exposure•Exposure is what is at risk from climatechange, e.g., – Population – Resources – Property•It is also the climate change that anaffected system will face, e.g., – Sea level – Temperature – Precipitation – Extreme events
Sensitivity• Biophysical effect of climate change – Change in crop yield, runoff, energy demand• It considers the socioeconomic context, e.g., the agriculture system• Grain crops typically are sensitive• Manufacturing typically is much less sensitive
Adaptive Capacity• Capability to adapt• Function of: – Wealth – Technology – Education – Institutions – Information – Infrastructure – “Social capital”• Having adaptive capacity does not mean it is used effectively
Vulnerability is a Function of …• More exposure and sensitivity increase vulnerability• More adaptive capacity decreases vulnerability• An assessment of vulnerability should consider all three factors
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)Includes “actual” (realized) or “expected” (future) changes in climate
Adaptation (continued)Two types of adaptationAutonomous adaptation or reactive adaptation tends to be whatpeople and systems do as impacts of climate change becomeapparentAnticipatory or proactive adaptation are measures taken toreduce potential risks of future climate change

WATERSHED DEVELOPMENT PROGRAMME (WDP)Improve and sustain productivity and production potentials of the dry/semi-arid regions of India through adoption of appropriate production and conservation technologies.Meet the needs of local rural communities for food, fuel, fodder and timber. Improve all types of lands, i.e., Government, Forest, Community and Private Lands falling within a watershed.
WATERSHED DEVELOPMENT PROGRAMME (WDP)WDPs, in short: A holistic approach to improve and develop the economic and natural resource base of dry/semi-arid/fragile regions. In a watershed development program the watershed is the unit for development rather than political or administrative boundaries
WDP Activities• i) Land Development: Levelling and terracing, improving soil quality and productivity; and watershed reclamation.• ii) Water Development: Promote in situ water harvesting and conservation, establish percolation ponds and open wells, tanks, small reservoirs, and improving water quality.
WDP Activitiesiii)Enterprises/Activities: Evolve appropriate farming systems, – encourage a crop mix of high value/high yield crops, – social/agro-forestry, – other income-generating activities like dairying, poultry-keeping, etc.
Some Illustrations of Benefits of WDPs• -Replacing seasonal/annual crops with agro- silvi, agrohorti, silvi-horti; systems on hill slopes/degraded lands. Benefits: reduce soil erosion; arrest surface run-offs.• -Training water to store excess water run-offs in farm ponds/percolation tanks. Benefits: improve groundwater recharge.• -Construction of earthen or vegetative bunds or barriers to surface run-offs in a watershed. Benefits: help in moisture conservation.
MGNREGA• National Rural Employment Guarantee Act2005 (NREGA)• Act guarantees 100 days of employment in a financial year to every household• A social safety net for the vulnerable groups and an opportunity to combine growth with equity• Structured towards harnessing the rural work-force, not as recipients of doles, but as productive partners in our economic process• Assets created result in sustained employment for the area for future growth employment and self-sufficiency
Climate Change / Variability in Semi-arid regionsPrecipitation is less thanpotentialevapotranspiration.Low annual rainfall of 25to 60 centimeters andhaving scrubby vegetationwith short, coarse grasses;not completely arid.

Biocharculture Biocharculture is the process of using Biochar, including cultivation of crops• Biochar is the charcoal produced from carbonaceous source material. Sink for atmospheric carbon dioxide in terrestrial ecosystems• Biocharculture is one of the means to integrate for sustainable cultivation and carbon sequestration.• Biochar is usually produced at around temperatures 300 to 600 degrees centigrade for example as found in the common biomass cook stoves.• Because of its macromolecular structure dominated by aromatic C, Biochar is more recalcitrant to microbial decomposition than uncharred organic matter
