The Concept
of Sustainable Development
Many of the ideas that are
now embedded in the concept of sustainable development have been around for
a long time – from as long ago as the work of Malthus on population growth in
the late 1700s. But the concept really only emerged during debate in the early
1970s following of a range of key publications drawing attention to man’s over-exploitation
of the environment, focusing on economic development and the growing global
concern about development objectives and environmental constraints, and examining
the inextricable links between environment and development.
While many of the environmental
management principles embodied in the concept of sustainable development are
derived from this ecological perspective, the social aspects are now also accepted
to be of equal concern alongside economic issues. In 1987 by the World Commission
on Environment and Development (WCED), otherwise known as the Brundtland Commission
(after its Chairperson, Gro Harlem Brundtland, Prime Minister of Norway) gave
this definition:
"Economic and social
development that meets the needs of the current generation without undermining
the ability of future generations to meet their own needs".
The goal of sustainable
development, while implicit in many national policies, gained global recognition
and committment following the UN Conference on Environment and Development (UNCED),
otherwise known as the Earth Summit, held 1992 in Rio de Janeiro.

A
Global Commitment
The 1992 Earth Summit approved
a set of five agreements, and although they all deal with the sustainable use
of the environment, Agenda 21 focuses in it's first principle on social aspects,
and lays out a global plan of action.
Agenda 21 - Principle 1
Human
beings are at the centre of concerns for sustainable development.
They are entitled to a healthy and productive life in harmony with nature.
The five agreements covered
at the Earth Summit are:
-
Agenda 21: a global
plan of action for sustainable development, containing over 100 programme
areas, ranging from trade and environment, through agriculture and desertification
to capacity building and technology transfer.
-
The Rio Declaration
on Environment and Development - a statement of 27 key principles to guide
the integration of environment and development policies (including the polluter
pays, prevention, precautionary and participation principles).
-
The Statement of Principles
on Forests - the first global consensus on the management, conservation
and sustainable development of the world's forests.
-
The Framework Convention
on Climate Change - a legally-binding agreement to stabilise greenhouse
gases in the atmosphere at levels that will not upset the global climate
system.
-
The Convention on Biological
Diversity - a legally-binding agreement to conserve the world's genetic,
species and ecosystem diversity and share the benefits of its use in a fair
and equitable way.

Meeting
the Goals of Sustainable Development
A commitment to meet the
needs of present and future generations has various implications. "Meeting the
needs of the present" means satisfying:
-
Economic needs -
including access to an adequate livelihood or productive assets; also economic
security when unemployed, ill, disabled or otherwise unable to secure a
livelihood.
-
Social, cultural
and health needs - including a shelter which is healthy, safe, affordable
and secure, within a neighbourhood with provision for piped water, drainage,
transport, health care, education and child development, and protection
from environmental hazards. Services must meet the specific needs of children
and of adults responsible for children (mostly women). Achieving this implies
a more equitable distribution of income between nations and, in most cases,
within nations.
-
Political needs -
including freedom to participate in national and local politics and in decisions
regarding management and development of one's home and neighbourhood, within
a broader framework which ensures respect for civil and political rights
and the implementation of environmental legislation.
Meeting such needs "without
compromising the ability of future generations to meet their own needs" means:
-
Minimising use or
waste of non-renewable resources - including minimising the consumption
of fossil fuels and substituting with renewable sources where feasible.
Also, minimising the waste of scarce mineral resources (reduce use, re-use,
recycle, reclaim).
-
Sustainable use of
renewable resources - including using freshwater, soils and forests
in ways that ensure a natural rate of recharge.
-
Keeping within the
absorptive capacity of local and global sinks for wastes - including
the capacity of rivers to break down biodegradable wastes as well as the
capacity of global environmental systems, such as climate, to absorb greenhouse
gases.
Balancing
Objectives
Sustainable development
includes social, economic and ecological objectives:
-
socially desirable,
fulfilling people's cultural, material and spiritual needs in equitable
ways.
-
economically
viable, paying for itself, with costs not exceeding income, and
-
ecologically
sustainable, maintaining the long-term viability of supporting ecosystems.
Sustainable development
will entail integration of these three objectives where possible, and making
hard choices and negotiating trade-offs between objectives where integration
is not possible. These negotiations will be greatly influenced by factors such
as peace and security, prevailing economic interests, political systems,
institutional arrangements and cultural norms.

Making
Trade-Offs
The aim of sustainable development
is thus to optimise the realisation of a society's many and different social,
environmental and economic objectives at one and the same time. Preferably,
this should be achieved through an adaptive process of integration, but more
usually it will require bargains (trade-offs) struck amongst the different interest
groups concerned. Critical to this process is the recognition that different
perspectives on environment and development are both inevitable and legitimate.
There could be, for example, very different environmental priorities between
aid donors, recipient governments and the poor of developing countries.
One way of looking at these
trade-offs is to take an economic approach and identify the human and natural
capital stocks that are needed for development. Explicit policies are required
to maintain and enhance our natural capital and the services it provides for
development, such as raw materials, freshwater and a stable climate. Within
natural capital, distinctions will need to be made between critical stocks,
which are irreplaceable and which should not be traded-off against social and
economic goals, and those which can be exchanged in return for building up technological
capital, thus maintaining constant levels of overall capital stocks.

The
Principle of Participation
The question then arises:
who should make the decisions on trade-offs ? Agenda 21 calls for the
widest possible participation in international negotiations, such as UNCED,
in national and local sustainable development strategy-making exercises and
in project design and implementation.
National governments
are responsible for providing the conditions which both permit and
facilitate the necessary dialogue and negotiation between all sectors
and interest groups in society. The development of national strategies
for sustainable development, called for in Agenda 21, could lead
to greater democracy, encourage an overhaul of institutional arrangements,
administrative procedures and legislative frameworks, as well as
fostering consensus among different strata and groupings in society.
