Consequences of climate change:

VulnerabilityVulnerability to climate change is the risk of

adverse things happening Vulnerability is a function of three factors:

Exposure

Sensitivity

Adaptive capacity

Exposure

•Exposure is what is at risk from climate change, e.g.,

– Population– Resources– Property

•It is also the climate change that an affected 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 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

SL framework: Determinants of adaptive capacity

Livelihood resources

Examples

Human Knowledge, Skills

Social Women’s savings and loans groups, farmer- CBOs

Physical Irrigation infrastructure, seed and grain storage facilities

Indian poverty

• Poverty is widespread in India, with the nation estimated to have a third of the world's poor. According to a 2005 World Bank estimate, 41.6% of the total Indian population falls below the international poverty line of US$ 1.25 a day (PPP, in nominal terms 21.6 a day in urban areas and 14.3 in rural areas).[1] A recent report by the Oxford Poverty and Human Development Initiative states that 8 Indian states have more poor than 26 poorest African nations combined which totals to more than 410 million poor in the poorest African countries.[2]

What is being done and how effective is it?1. Communities continuously finding better options to reduce their

vulnerability 2. Few responses decrease the sensitivity of the system 3. Majority are short-term fixes - reduce vulnerability temporarily but

decreases the resilience of the system

Climate Changes in India

• Increase in surface temperature by 0.4 degree C over the past century.

• Warming trend along the west coast, in central India, the interior peninsula, and northeastern India.

Climate Changes in India

• Cooling trend in northwest India and parts of South India.

• Regional monsoon variations: increased monsoon seasonal rainfall along the west coast, northern Andhra Pradesh and North-western India, decreased monsoon seasonal rainfall over eastern Madhya Pradesh, North-eastern India, and parts of Gujrat and Kerala.

Climate Changes in India

• Observed trends of multi-decadal periods of more frequent droughts, followed by less severe droughts.

• Studies have shown a rising trend in the frequency of heavy rain events and decrease in frequency of moderate events over central India from 1951 to 2000.

Climate Changes in India

• Records of coastal tide gauges in the north Indian ocean for the last 40 years has revealed an estimated sea level rise between 1.06-1.75 mm per year.

• The available monitoring data on Himalayan glaciers indicates recession of some glaciers. 27

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 Activities

• iii)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.

Climate Change will put additional stress in

rural areas

In the life of a farmer climate Variability and

Extreme events are more important

than climate change

MGNREGA• 'National Rural Employment Guarantee Act'2005 (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

• Operationalised from 2nd February, 2006 in 200 selected districts, extended to 130 more districts in 2007-08.

• The remaining districts (around 275) of the country under the ambit of NREGA from 1st of April, 2008

Agriculture• India ‘s population is 1.21 billion in 2011. 67% are rural. Majority

are in agriculture. • Importance of agriculture in Indian economy. Although it

contributes only 15% of GDP, the share of workers is about 55%.• Marginal and small farmers dominate• Major crops are rice, wheat, maize, coarse cereals, groundnut,

cotton, sugarcane, fruits and vegetables• 60% of cultivated area is rainfed as only 40% of area is under

irrigation.• Rural poverty is 41%in 2004-05. • Agriculture is a ‘State Subject’. In other words, the policies of

provinces are also important

Climate Change / Variability in Semi-arid regions

Precipitation is less than potential evapotranspiration.

Low annual rainfall of 25 to 60 centimeters and having scrubby vegetation with short, coarse grasses; not completely arid.

Climate Change / Variability in Semi-arid regions

Climate Variability and extremes are an expected characteristic of semi-arid lands.

The people vulnerable to droughts, which trigger frequent subsistence crises

Increasing crop failures, dislocation, famine, poverty, increases stratification and the social inequities.

Vulnerability of poor in rural areas

Two-thirds of households derive income directly from natural sources

Natural resources are threatened by stresses Biotic & Abiotic

Agriculture & natural resource based livelihoods at immediate risk

Rural poor do not have resources to cope

Nature of Works

Water based

• » Water conservation • » Water harvesting• » Micro and minor irrigation works• » Provision of irrigation facilities• » Desilting of tanks• » Renovation of traditional water bodies• » Flood control and protection works

Land based

• » Land development

Forest/ Agro--Forestry

• » Afforestation• » Horticulture

Infrastructure

• » Rural roads

Conservation technologies

Stress-tolerant, climate-resilient varieties of seeds, drip irrigation, zero-tillage, raised-bed planting, laser-levelling, Systems of Rice Intensification (SRI), can build adaptive capacities to cope with increasing water stress, providing “more crop per drop”.

BIOCHARCULTURE

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

Biocharculture Adaptation benefitsSecuring the crop from

drought and climate variabiiity

Reclaim the degraded soils, water conservation,

Lessen the impact of hazardous pesticides

and complex chemicals & to reduce plant

uptake.

reducing emissions and increasing the

sequestration of greenhouse gases

Conversion of crop residue into Biochar an

option and address carbon sequestration

Increase in crop yieldincreases in C, N, pH, and available P to the

plantsImpacts of Biochar last more than 1000 years.
