Climate-related shocks and stresses, already
a major obstacle to poverty reduction, will
worsen with climate change

Flows into poverty

Flows out of poverty
14% per year
Net flows
2% per year
Drought, irrigation
failure, or crop
disease involved in
44% of the cases
Increasing the flow from
12% to 13% would halve
poverty reduction
Decreasing the flow from 14% to
13% would halve poverty
reduction
Weather events keep people
poor through asset and human
capital destruction

Common shocks that drive or keep people in
poverty….
Spikes in food
prices and
shocks to
agricultural or
ecosystem-based
income
Natural disasters
such as
droughts, floods,
and storms
Disease and
health shocks,
such as malaria,
diarrhea,
stunting, and
mental disorders
… will be worsened by climate change
5
Poor people are often more exposed to these
shocks – take the case of Nigeria
6
Poor people are 50%
more likely to be flooded
Poor people are 130%
more likely to be
affected by a drought
Poor people are 80%
more likely to be
affected by extreme heat

flood zones

based on Winsemius et al., forthcoming
Poor people are often more exposed to these
shocks – take the case of urban floods
Poor people are always much more vulnerable to
natural hazards

Indonesia Poor 8% $0.5/day
Non-poor 21% $2/day
Poor people have less access to support

Rapid, inclusive, and climate-informed
development can prevent most
consequences of climate change on
poverty till 2030.
Main Message #2
13
Absent such good development, climate change
could add more than 100 million people in
extreme poverty by 2030.
14
Then, we introduce climate change in these two scenarios.
And we explore what development can achieve to reduce
future climate change impacts
Good development – rapid, inclusive and climate-informed –
can prevent most of the impact of climate change on poverty
Up to 16 Million more people below the poverty line in 2030 due to climate change
Prosperity Scenario
Absent good development, climate change could keep more
than 100 million people in poverty, especially in Sub-Saharan
Africa and South Asia
Up to 122 million more people below the poverty line in 2030 due to climate change
Poverty Scenario
Better education, transport infrastructure, and connection to markets can
reduce climate change impacts through agriculture
Good development includes progress in the
agricultural sector and infrastructure
17
Good development includes financial inclusion
that protects people against all shocks…
• Mobile banking will help.
• But bank account must be
designed for poor people…
• … and they need consumer
protection.
18
More
intense
events
Richer
households
Basic social protection, remittances,
and revenue diversification
Market insurance
Savings, credit, and
scaled-up remittances
Smaller
events
Poorer
households
Government
reserve funds
Government
insurance and
contingent finance
Social insurance
and scaled-up
social safety nets
International aid
Good development includes strengthened social
protection systems
Good development includes universal heath
coverage and better health care quality…
In Rwanda, the government started
investing in universal health coverage in
1994. Today nearly 80 percent of its
population is insured.

- Climate-smart
agriculture, for instance
mixing trees with annual
crops
- Heat-tolerant crops
- Water reservoirs and
groundwater
management
- R&D for tropical
agriculture
- Early warning systems,
taking into account
behavioral issues
- Land-use plans that
account for future
changes in climate (and
the uncertainty in
projections)
- Coastal and floods
protection including
mangroves and wetlands
- Monitoring and
surveillance systems for
emerging health crises
- R&D toward diseases
that will increase due to
climate change
Good development needs to be
complemented with targeted adaptation
policies in the three key sectors
22
Many Policy Decisions Have Long-Term
Consequences and are climate-sensitive
23
Immediate mitigation is required to
remove the long-term threat that
climate change creates for poverty eradication.
Mitigation need not threaten short-
term progress on poverty
reduction provided that policies are well
designed and international support is available.
Main Message #3
24
So even the limited changes we expect by
2030 could have a large effect on poverty
25
2030
Source: IPCC 2014
Long-term climate change is likely to exceed
adaptation capacity
26
Unmitigated climate change
can threaten the convergence
of poor regions to developed-
country life standards, even
with adaptation and trade
~3oC
~2oC
Baselines
… but mitigation should not slow down poverty
reduction
Stabilizing climate change requires to bring net
emissions to zero…
27
Start with measures with immediate and local
co-benefits
28
Of which there are many
29
When it reformed energy
subsidies, Indonesia
deployed a program of
cash transfers that
provided 30% of the
population with $30 per
quarter, significantly
more than the increase in
energy costs.
Source: based on Arze del Granado et al (2012)
Policies can be designed to benefit the poor
But very poor countries cannot protect poor people
and need international support
Distributional impacts of replacing $100 of
fossil fuel subsidy by a universal cash transfer
An optimistic take-away?
The future is not set in stone. We have a window of opportunity to
achieve our poverty objectives in spite of climate change.
31
To deal with short-term
impacts that cannot be
avoided with emission
reductions
Rapid, inclusive, and climate-
informed development, with
social protection and universal
health coverage
Targeted adaptation
interventions such as flood
management infrastructure and
more heat-tolerant crops
To deal with long-term
impacts that cannot be
avoided with adaptation and
good development
Immediate and pro-poor
emissions-reduction policies
that protect poor people
against negative impacts
International support to
prevent the trade-off
between poverty reduction
and emissions reduction
