BIODIVERSITY
ENTRY POINT PAPER
Izabella
Koziell, DFID
‘A social problem rooted in a biological world’ (Swanson, 1997).
Introduction
- This
paper discusses the DFID approach to biodiversity, in the context
of the goal to reduce by one half the number of people living in extreme
poverty by 2015. Following an introduction to the concept of biodiversity
as a resource, the paper discusses how biodiversity should be viewed
by the bilateral programme in support of sustainable rural livelihoods.
Finally, the paper discusses how this relates to the wider issue of
the global value of biodiversity.
What
is biodiversity?
- Biodiversity
is described as the variety of living organisms and is often
considered at three levels: genetic, species and ecosystem (Convention
on Biological Diversity, 1993; WRI, 1992; McNeely et al., 1990;
Wilson, 1989).
- Biodiversity
has resulted from a gradual accumulation of differences between
individual organisms throughout four billion years of evolution. In
our time span, biodiversity is therefore a non-renewable resource.
Once lost, this diversity cannot be renewed. In Sri Lanka, for example,
the number of rice varieties has dropped from 2,000 in 1958 to less
than 100 today (WCMC, 1992). In contrast, rice - considering biomass
irrespective of biodiversity - remains a renewable resource (Swanson,
1997).
- The
distinction between biodiversity and biomass is important but the
relationships are not always simple or clear. A reduction in biodiversity
may or may not affect biological productivity, stability or ecological
processes (WRI, 1989). For example, productivity of a maize monoculture
can be higher than from a diverse production system per unit area
- but will require higher inputs and may be much more susceptible
to disease. North America, Madagascar and Australia have lost a large
share of their vertebrate megafauna within the recent past, yet there
is, as yet, scant evidence of profound ecosystem instability (Myers,
1996). Ecosystem processes, such as carbon sinks, can be maintained
either by a tract of biodiverse rainforest or a uniform plantation
of eucalyptus trees. However, a eucalyptus plantation would probably
provide less cycling of minerals and soil nutrients and support fewer
plants and animals (Myers, 1996).
- The
focus of this paper (and the associated Linking Policy and Practice
in Biodiversity (LPPB) project) will be on the specific contribution
of biodiversity as a resource - rather than biomass - to sustainable
rural livelihoods.

Linking Policy
and Practice in Biodiversity (LPPB) Project
The LPPB project aims to improve
and clarify our understanding of the inter-relationships between
biodiversity and development, particularly at the bilateral country
programme level, in order to assist DFID in its decision-making.
It also aims to clarify linkages between local, national and global
concerns. The project will consider both wild and domestic biodiversity
across a range of productive sectors.

How
does biodiversity relate to sustainable rural livelihoods?
6.The
sustainable rural livelihoods approach has shifted the emphasis towards
first considering people, and then examining how they manipulate different
capital stocks (natural, physical, social, financial and human) to augment
their livelihoods. Biodiversity represents a part of natural capital.
Natural capital provides the material, energy, processes and information
which people combine to produce and accumulate other capital stocks
- physical, human and financial - from which are derived positive livelihood
outcomes. Thus, biodiversity should be seen as a means of contributing
to sustainable rural livelihoods, rather than an end in itself.
- Both
wild and domesticated biodiversity hold significant social, aesthetic,
cultural and economic values for human societies. Some of the generic
economic values are displayed in Table 1 below.

- Some
of these categories have direct use to people, and benefits arising
are more easily measurable and quantifiable, e.g. financial returns
gained from harvesting a stand of timber. Others are less easily quantifiable,
because they provide functional values, e.g. the contribution of forest
diversity to watershed protection, or depend upon potential future
rather than short-term benefit, or are ‘global’ and cannot be captured
by, or allocated to, any one individual group of people. The implications
of this are discussed in the final section of the paper.
- The
use values can be more easily realised through a range of management
activities that can involve combinations of approaches along a spectrum
from total protection to total conversion of biodiversity.
These management activities offer a series of options for use of
biodiversity, some being more appropriate than others within the specific
ecological and socio-economic context. Both conversion and protection
of biodiversity can bring different benefits - and different costs
- to different people. It is important to clarify who is likely
to receive benefits, and who is likely to suffer the costs,
in both the shorter and longer term.
- Benefits
of conversion. Over the millennia, people have been converting
natural capital to other forms of capital stock. Biodiversity provides
the range of species and varieties, the careful selection of which
has enabled the successful expansion of those species and varieties
that are particularly appropriate for converting to food, fuel, shelter,
clothing and other goods. Such manipulations have provided the basis
for wealth accumulation and appropriation of other capital assets,
albeit not always on an equitable basis. As a result, countries that
have ‘converted’ biodiversity are often rich materially in comparison
to those that have not. It is therefore understandable that ‘unconverted’
countries are keen to follow similar and safely ‘proven’ development
paths.
- Costs
of conversion. Despite the uncertainties that surround measurement
of biodiversity, there is now ample evidence to show that biodiversity
is declining. Whilst decline associated with conversion has provided
distinct benefits to certain groups of people, it can also be associated
with heavy livelihood losses, particularly to those who are politically
and socially marginalised, or the ‘poorest of the poor’. These groups
have often continued to remain directly dependent on biodiversity
for both on-farm and off-farm livelihood activities. Loss of this
biodiversity undermines their production choices, food security and
increases exposure to risk. In this context, it is not generally the
loss of a single species that is meaningful, but the loss of large
components of biodiversity. For poor and marginalised groups, protection
and maintenance, and improved access to, biodiversity can often contribute
more to sustainable livelihoods than conversion.
- The
benefits of maintaining and protecting biodiversity. Protection
and sustainable use of biodiversity can also provide unique values
(Box 1 below). The challenge lies in ensuring these values can be
captured and retained by local people as well as broader groups.
|
Box 1: Potential
benefits provided by maintenance or sustainable use of biodiversity
|
|
· A
diversity of species provides a range of economic and investment
opportunities.
· Food
security is improved by a range of varieties which help reduce
the risk of loss due to pests, and increase tolerance to climatic
stress.
· Land
can have greater biomass output over longer periods of time when
biodiverse (non-diverse farming systems succeed by economies of
scale, and over shorter periods of time - often requiring high
levels of inputs to sustain yields).
· Protection
is provided against epidemic pathogens - the more genetically
uniform a population is, the more vulnerable it is to epidemic
disease.
· Genetic
information is available to plant breeding and pharmaceutical
industries the outputs of which contribute to food security and
improved human health.
· Exposure
to environmental risk is reduced through supporting ecosystem
processes which protect poor people from variables such as drought
and flood.
· Nutrition
and health are improved by providing a source of medicines and
vitamins for humans and livestock.
· A
range of unique social and cultural identities which have developed
through the establishment of different people-landscape interactions
are maintained.

- Costs
associated with maintaining areas of high biodiversity. In addition
to the opportunity cost of forgone gain from conversion (to monoculture,
for example), costs include livestock and crop losses from wild animal
encroachment and predation, weeds and pest infestation. In some situations,
it is the activities designed to maintain biodiversity which
have impacted negatively upon livelihoods. For example, the establishment
of protected areas has sometimes been associated with resettlement
programmes, human displacement and restrictions on access to local
resources. Even where protected areas bring tourism, gains from tourism
often benefit outsiders rather than local communities. Such protected
area programmes have sometimes led to serious conflicts between local
communities and government park departments and an escalation in the
costs of protection. Finally, the banditry, poaching and smuggling
associated with ‘wilderness’ areas has occasionally had significant
negative impacts.
How
should DFID support the contribution of biodiversity to sustainable
rural livelihoods?
- DFID
is committed to eradicating poverty. Thus, certainly in the context
of the bilateral programmes and the sustainable rural livelihoods
approach, the focus should be on maximising social and economic
benefits that arise out of the protection, sustainable use or conversion
of biodiversity, and seeking their fair and equitable distribution.
- The
shift in emphasis of the sustainable rural livelihoods approach implies
the term ‘win-win’ should no longer be understood to mean the Purpose
is both poverty reduction and biodiversity maintenance. The Purpose
of the bilateral programme should be poverty reduction. A ‘win-win’
situation occurs where maintenance of biodiversity is the best means
of achieving poverty reduction.
- In this
context:
- Protectionist
interventions for maintaining biodiversity will be of relevance only
where the benefits to local people arising from protection exceed
those arising from an alternative activity. In Bangladesh, for example,
local people establish ‘brush parks’ which create protected habitats
for breeding stock by restricting fishing. Such a mosaic of protection
and use of biodiversity has applications in other sectors, but the
link between maintaining a reservoir of biodiversity and supporting
local livelihoods must be demonstrable.
- Between
the extremes of total protection and entire conversion, most options
will involve a degree of partial conversion (involving some loss of
biodiversity) and sustainable use. Once again, such activities should
be supported only where they result in greater benefits for poor people
than other alternatives. For example, in Java, during the pre-colonial
era, large urban populations were supplied successfully by the garden
farming system which was extremely biodiverse, encouraging integration
of both domestic and wild elements (Christanty et al., 1986).
Examples of sustainable use of wild biodiversity are found in community-based
wildlife management programmes.
- Conversion,
which may reduce biodiversity, will also continue to be assessed against
what it contributes to sustainable rural livelihoods. DFID should
aim to ensure the equitable distribution of benefits, and also that
conversion of biodiversity-rich areas for wider benefit does not undermine
people’s welfare within that locality.
What
are the trade-offs to consider in the management of biodiversity for
development?
1.
In the section above, we argue that biodiversity should be considered
as a resource which can contribute to sustainable rural livelihoods
in many different ways, directly and indirectly, in the short and long
term. We point out that the greatest challenge lies in ensuring, and
maintaining, objectivity over decisions regarding effective use of biodiversity
for poverty reduction. Such an approach entails questioning some of
the general assumptions that continue to be made regarding relationships
between biodiversity decline and human development. It involves ensuring
that decisions are framed within the specificity of the local or regional
context. And it involves recognising that there are difficult trade-offs
(or generally combinations of trade-offs) to make in such decisions.
These include:
- long-term
vs. short-term imperatives
- quantifiable
value vs. non-quantifiable value
- anticipated
value vs. actual value
- local
value vs. global value.
How
should DFID make these choices?
Long-term
vs. short-term imperatives
2.
Sustainable rural livelihoods demand sustainable use of resources. For
example, DFID would not promote conversion to a less diverse system
for short-term gain if such a system was unsustainable.
3.
However, the short-term needs of poor people and governments cannot
be ignored. Vulnerability, need or greed, may lead people to take decisions
based on a short-term view. Too much unpredictability lies between the
now and the long-term future. For example, colonisers in forest margins
may choose farming methods - such as rearing cattle - which are heavily
supported by government incentives, and which otherwise would not be
economically viable and are unsustainable in the long-term. Turning
forest to farmland may support a family for two years, but after that
the only option may be to burn more forest (Blench, 1998). How should
DFID and partner governments assist in making such choices?
Quantifiable
value vs. non-quantifiable value
4.
When considering management options for reducing poverty through direct
use of biodiversity, economic benefits are more easily measurable. But
how does one quantify the value of protecting a watershed? More difficult
still, how does one measure the spiritual or cultural value of biodiversity
to local people? How do we weigh the measurable against the un-measurable
when making management choices?
Anticipated
value vs actual value
5.
Closely related to the two categories above, is the question of anticipated
values. For example, there may in the future be great value in bioprospecting.
But technological improvements in drug development may make these values
worthless - or what value exists will be captured by agents other than
local people. How should DFID balance such potential benefit
against the certain benefit of, for example, converting that
biodiverse system?
Local
value vs. global value
6.
We need to recognise that our own concerns about climate change, endangered
species and preserving ‘the natural order of things’ may be significantly
different to the priorities of most poor people. This does not mean
our purpose (i.e. reducing poverty) is different; the differences manifest
themselves in how we choose to achieve that purpose. Global biodiversity
benefits, as defined by us, cannot be allocated to any individual group
of people. Therefore, the costs of maintaining global biodiversity should
not be transferred onto poorer groups.
7.
The bilateral country programme has the remit of reducing poverty in
any particular country. Ideally, global concerns such as these would
not therefore enter bilateral decisions. These are issues for multilateral
and international funding. However, bilateral programmes may sometimes
find themselves serving the global - in addition to the local - good.
In such cases, the programme must be sure that livelihoods of local
people, or the effectiveness of the programme in reducing poverty, are
not compromised in any way.
