Poverty and Environment: The Linkages
• Internationally, there is a known correlation between
poverty and environmental danger
• Because of lack of money, education, and concern, poor
families disregard the environment to uphold a
“survival mentality”
• Poor countries do not see the environment as priority
because of all the other problems happening within
the society, so nothing is done to conserve
• These people are not to be blamed for the world’s
environmental problems, we must look ahead and
focus on a solution

• First picture shows a grossly polluted canal in Mali
• The 2nd is people living next to that canal & using this
polluted water – because they do not have any other source of
water.
• So they get sick from water borne diseases & malaria – ie
pollution causes sickness & the costs associated with that

Poverty and Environment nexus
Two of the most important global issues today are pervasive poverty and
problems related to environmental degradation. The causal factors are
complex.
Since the 1970s it has been almost universally agreed that poverty and
environmental degradation are inextricably linked.
Holmberg (1991) pointed out that the relationship between the environment and
poverty is not so straight forward.
Insufficient attention had been paid to some intuitive and field experience and
that there was even a possibility of conflict between the goals of poverty
alleviation and environmental protection.
A number of studies have been carried out on how both poverty and wealth
have impacted on the environment, resulting in a number of environmental
threats such as degradation of the soil, water and marine resources which are
essential for life supporting systems, pollution which is becoming health
threatening, loss of biodiversity and global climatic changes which
jeopardize the very existence of life on the planet.

19.
The World Commission on Environment and Development
(Brundtland Commission) wrote (1987):
“Poverty is a major cause and effect of global environmental
problems. It is therefore futile to attempt to deal with
environmental problems without a broader perspective that
encompasses the factors underlying world poverty and
international inequality.”
The links between poverty and environment were also seen to be
self-enforcing. The Commission also wrote:
“Many parts of the world are caught in a vicious downwards
spiral: poor people are forced to overuse environmental
resources to survive from day to day, and their impoverishment
of their environment further impoverishes them, making their
survival ever more difficult and uncertain.”
Poverty and Environment nexus

20.
The environment-poverty nexus is a two-way relationship.
Environment affects poverty situations in three distinct
dimensions:
i. by providing sources of livelihoods to poor people,
ii. by affecting their health and
iii. by influencing their vulnerability.
On the other hand, poverty also affects environment in
various ways:
i. by forcing poor people to degrade environment,
ii. by encouraging countries to promote economic
growth at the expense of environment, and
iii. by inducing societies to downgrade environmental
concerns, including failing to channel resources to
address such concerns.

poverty– environmental interactions:
Conclusions from UNDP/EC
Poverty necessarily leads to environmental
degradation. Studies have failed to show a
common pattern in the relationship; in certain
situations the poor are immediately
responsible for degradation while in others they
are seen to take great care in maintaining or
improving the environment.

1. Poverty necessarily leads to environmental
degradation.
Studies have failed to show a common pattern in the
relationship; in certain situations the poor are
immediately responsible for degradation while in
others they are seen to take great care in maintaining
or improving the environment.
poverty– environmental interactions:
Conclusions from UNDP/EC

23.
2. It is necessary first to tackle poverty concerns
before dealing with environmental improvement.
Some of the most extreme degradation takes place in
boom (good) periods rather than slumps (collapses);
neither rural poverty nor environmental programmes
should be conducted in isolation but rather as part of
an integrated and well-analyzed approach.
poverty– environmental interactions:
Conclusions from UNDP/EC

24.
3. Poor people are too poor to invest in the
environment.
Where incentives are favourable, poor people mobilize
resources, particularly labour, and invest in
environmental improvement. This is not to suggest
that external help cannot also be a valuable aid.
poverty– environmental interactions:
Conclusions from UNDP/EC

25.
4. Population growth necessarily leads to
degradation.
Most agricultural landscapes can support higher
populations in a sustainable way by adopting more
intensive technologies and farming methods; in some
situations population growth may provide economies
of scale helpful to the economy.
poverty– environmental interactions:
Conclusions from UNDP/EC

26.
5. The poor lack the technical know-how for good
resource management.
Although lacking in formal education, poor people have
an enormous store of indigenous technical knowledge
and develop sophisticated resource management
systems. Supposedly primitive water and agricultural
systems can be equitable, efficient and sustainable,
especially under low population densities.
poverty– environmental interactions:
Conclusions from UNDP/EC

27.
6. Markets always lead to efficient allocation of
resources.
While markets can be conducive to good management,
they may also encourage over-exploitation of natural
resources (e.g. timber and non-timber forest
products). This is especially so where factor prices do
not reflect wider social and environmental costs.

Conclusions from UNDP/EC

Myth 1- “Poor people are the principal creators of
environmental damage.”
Not true. Even though poor people bear the brunt of
environmental damage, the irony is that they are not its
principal creators. It is the rich who pollute and
contribute most to global warming. They are the ones
who degrade the global commons, making resources
scarce for poor people.
In many areas, the non-poor, commercial companies, and
state agencies actually cause the majority of
environmental damage through land cleaning, agro-
chemical use, and water appropriation (owning).

29.
Myth 1- “Poor people are the principal creators of
environmental damage.”
The rich also generate more waste and create stress on
nature’s sink. Thus, poor people become victims of the
consumption levels and patterns of the rich.
One of the environmental challenges that stem from
growing poverty and environmental damage is that it
pushes more and more people to the periphery – to the
most ecologically fragile land where they become even
more vulnerable. Yet there are many examples in which
poor people take care of the environment and invest in
improving it.

30.
Myth 2 - “The poverty-environment nexus basically
stems from low incomes.”
It’s not that simple.
Arguments that maintain that poor people degrade the
environment basically explain the poverty-environment
nexus in terms of income levels only.
The poverty- environment nexus is more complex.
Questions of ownership of natural resources, access to
common resources, the strength or weakness of
communities and local institutions, the way information
about poor people’s entitlements and rights to resources
is shared with them, the way people cope with risk and
uncertainty, the way people use scarce time – all these
are important in explaining the environmental
behaviour of poor people.

31.
Many of the natural resources that are degraded are communal
property. Rights are ill-defined, often because they were
originally defined within a local social and political framework
that is no longer there.
Institutions for managing common property that reflect the
consensus of owners and can control use are lacking. In
ecologically fragile ecosystems, people tend to minimize risks,
not maximize output, whether they are poor or rich.
Over-exploitation of sources of fuel-wood is linked more to the time
available to women than to their poverty status. There is a gender
dimension, but not necessarily an income dimension.
Many factors shape human behaviour towards the environment,
some related to poverty or affluence (wealth), others independent
of either income or poverty.
Myth 2 - “The poverty-environment nexus basically
stems from low incomes.”

32.
Responding to environmental threats
• Demand for environmental quality ...
– … is a luxury - the poor are too busy thinking about
basic survival to concern themselves with
environmental issues
• Ability to respond to such demands ...
– … is dependent on aggregate wealth - economic
prosperity and technological sophistication allow
nations to react to environmental challenges
– Environmentalism is the exclusive concern of the rich,
in the advanced industrial nations

33.
Are these
concerns
exclusively
found in
rich
nations?
Understanding responses
• Out of concern for nature
– … as a source of cultural, spiritual, social
and economic value ...
• To mitigate anthropogenic influences on
the natural environment
– … pollution, resource depletion, extinction
of species ...
• To reduce the impacts of environmental
changes on human society
– … health impacts, livelihoods, needs, well-
being ...

34.
Views on poverty-environment linkages
• Conventional view
– Deterministic relationship: if one is poor, then one degrades
the environment
– Poverty is negatively related to sustainable development -
short time horizons of the poor
– Policy: need for economic growth to break the downward
spiral: World Bank 1992
Environmental
degradation
Poverty

35.
Alternative perspective (viewpoint)
• Political economy
– Why are people poor? Poor as proximate causes, but (global)
inequalities as the ultimate causes
– Evidence that the poor can and do care for the environment:
effective environmental stewardship
– The poor as environmental activists: new social and ecological
movements; grassroots political action
– Policy - remove inequalities
Environmental

Inequality
(power, wealth)

36.
• Market/institutional failure
– Price signals - perverse subsidies/taxes
– Tenure policies/property rights
– Legal framework
– Implementation capacity
– Competing policy demands
– Policy – correct market/institutional failure

imperfections
Alternative perspectives (viewpoints)

37.
• Reversing the causality
– Dependence of the poor on natural resources for their
livelihoods: CPR studies
– Impact of internal and external pressures is to undermine the
sustainability of the local resource base
– Policy - improved environmental sustainability as a poverty
alleviation strategy

Understanding human well-being
• Multiple dimensions of well-being
– Physical/financial resources - wealth
– Human resources - education, health
– Natural resources - ecosystem services
– Political resources - democracy, accountability
– Social/cultural resources - networks, norms, relationships
SUSTAINABLE LIVELIHOODS (SL)

Ecosystem services
• Definition
– Ecosystem services are the conditions and processes
through which natural ecosystems, and the species
that make them up, sustain and fulfil human life.
Daily et al 1997
* Provisioning functions
* Regulating functions
* Enriching/cultural functions

41.

storage, reduced
seepage and
evaporation, clean
water
Flood – rainwater
absorption, excess
water drainage,
flow regulatory
mechanism

44.
Ecosystem services: provisioning
• Magnitude/rate of goods harvested (‘flows’),
Examples:
– Food
– Micro-organisms, plant and animal products
– Genetic material, biochemicals & pharmaceuticals
– Fuels/energy
– Fodder
– Fibre
– Non-living material
– Fresh water

45.
Ecosystem services: regulating
• Life support functions, determined by ‘stock’
of the ecosystem,
• Examples:
– Purification of air and water
– Mitigation of floods and droughts
– Detoxification and decomposition of wastes
– Preservation of soil and soil fertility
– Pollination of crops and vegetation
– Control of pests
– Dispersal of seeds
– Maintenance of biodiversity
– Stabilisation of climate

46.
Ecosystem services: enriching/cultural
• Beliefs and values surrounding natural forces,
providing spiritual/religious/cultural support
(determined by ‘stock’),
• Examples:
– Spiritual components
– Aesthetic values
– Social relations and values
– Educational/scientific values

47.
Ecosystem services: well-being issues
• Provisioning: access of the poor for basic
needs; distributional issues
• Regulating: equitable sharing of benefits and
costs associated with protection
• Enriching/cultural: conflicting cognitive
paradigms and value/moral systems
Potential conflict between these services, but
also scope for synergy/win-win scenarios
