Objectives

• To develop alternative socio-economic scenarios that

take into consideration a sustainable development

objective for India

• To develop a conceptual frame for indicative economic

costs of policies for adaptation to climate change,

specific focus on vulnerable groups.

• To illustrate the methodology with detailed studies,

focusing on agriculture as a key sector

Methodology• Key markers of socio-economic vulnerability and

adaptive capacity were identified

• These include Geographical (inter-state variation and

coastal location), Demographic (inter-state population

distribution) and Coping vulnerability (income

differentials and access to basic facilities)

• Socio-Economic variables impacting each of the above

(through either an increase/decrease in vulnerability)

are then interacted in a dynamic simulation model

• Model provides: (a) alternative development pathways

through short to medium term projections over (b)

varying time scales (c) key parameters which can be

influenced to achieve desirable outcomes for

decreasing vulnerability.

Emerging Scenarios

• Time scale from current time period till 2030

• Reference scenario has current expectations and

assumptions of structural stability, and, concerns for

vulnerability without climate change impacts – results

available

• Optimistic Scenario improves on reference with rapid

technological progress and adaptive strategies –

results available

• Longer term Scenario Simulation – in progress

• Indicative Costs – framework developed; ongoing work

Uncertainty Issues

• TFP, technological progress

• Limiting – cap values : land availability, irrigation

potential, population, relative international prices

• Turning points – thresholds : where these lie and extent

of certainty of occurrence

Quality Assurance

• Face Validity through repeated iterations – expected

and consistent signs and directions of flows

• Historical behaviour tests

• Reality checks with extreme values for parameters

Page 11: Developing Socio-Economic Scenarios for India - Purnamita Dasgupta

11

Adaptation Framework

• Response Levels

– Variables determining potential for adaptation: education,

technological development

– Variables impacted by the potential: e.g. water use efficiency

• Drivers of Change

– Policies - State; Initiative – Public or Private or both

– Agency – State as Enabler; Individual and Civil society –

diffusion, uptake, funding

Page 12: Developing Socio-Economic Scenarios for India - Purnamita Dasgupta

12

Adaptation Framework

• Costs

– Knowledge Advancement Costs : Awareness and

Media, R & D, Institutional Development

– Sustainability Transition Costs: building a climate

resilient society - most sectoral, context specific

approaches/estimates capture these (on track with

developmental goals) e.g.: R & D to installation of

early warning systems; from institutional

development to crop insurance at incremental

premiums for climate change

Page 13: Developing Socio-Economic Scenarios for India - Purnamita Dasgupta

13

Some Conceptual Concerns

• Developmental goals well defined for short term (e.g. MDGs);

taken care of in setting the time frames and targets (e.g.

literacy, poverty, access to basic amenities)

• Adaptation Costs – in short run cover for derailment of the

economy from the desired time path

• Currently available CC data for 2071-2100; socio-economic

modeling limitations beyond 2030.

• Therefore, adopt a Systems Equilibrium approach ----

Moving from last three decades till 2004-05, to a future 30 year

period: 2071 to 2100.

Advantage – CC data available, disadvantages – too much

uncertainty to risk putting one number to it, even for the

economist!!!

For the present, See Adaptation costs in terms of directions of

change. Illustrate for food grain production.

Indicative Transition & Knowledge Costs

Adaptation to changing water availability for

agriculture in vulnerable areas

• Costs of weather insurance for typical rainfed

agriculture – private (esp. large and medium); social

/ government (small and marginal)

• Cost of water saving technology (drip and sprinkler

irrigation) – mostly private costing

• Cost of R & D in low water using crops – social/

government cost

• Cost of institutional development and resilience

build up for first two – both private and public; not

so for last. Rather, private agent may have incentive

to move into different land use.

Page 19: Developing Socio-Economic Scenarios for India - Purnamita Dasgupta

19

Adaptation Costs

• Various definitions and conceptual inconsistencies

exist in adaptation literature and available estimates

• Anticipated costs which maybe incurred by public

and private agents to plan for a change foreseen

with reasonable accuracy

• Critical – precision of extent and probability of

climate change impacts; incremental attributable to

CC; agency which bears the cost.

• Adaptation Funding for apportioning of costs between

2010 and 2100

• NREGA, BPL
