BR
 Biosphere reserves are areas of terrestrial and coastal
ecosystems
 Biosphere reserves are sites established by countries and
recognized under UNESCO's Man and the Biosphere (MAB)
Programme
 They promote
 sustainable development based on local community efforts
and sound science.
 solutions to reconcile conservation of biological and cultural
diversity and economic and social development through
partnerships between people and nature.
 They serve as 'living laboratories'
 for testing out and demonstrating integrated management of
land, water and biodiversity and
 demonstrate innovative approaches to sustainable
development from local to international scales.

BR
 They are internationally recognized, nominated by national
governments and remain under sovereign jurisdiction of the
states where they are located, yet they share their experience
and ideas nationally, regionally and internationally within the
World Network of Biosphere Reserves (WNBR).
 The first biosphere reserve of the world was established in
1979, since then the network of biosphere reserves has
increased to 580 in 114 countries across the world (MAB,
2012).
 BRs are thus special environments for both people and the
nature and are living examples of how human beings and
nature can co-exist while respecting each others’ needs.
 Direct Beneficiaries of the Biosphere Reserves are the local
people and the ecological resources and indirect
beneficiaries are scientists, government decision makers
and the world community.

Functions of biosphere reserves

Zones of a Biosphere Reserve
The core area
 It needs to be legally established and give long-term
protection to the landscapes, ecosystems and species
it contains.
 It should be sufficiently large to meet these
conservation objectives.
 As nature is rarely uniform and as historical land-use
constraints exist in many parts of the world, there may
be several core areas in a single biosphere reserve to
ensure a representative coverage of the mosaic of
ecological systems.
 The core zone is to be kept free from all human
pressures external to the system.

Zones of a Biosphere
Reserve
A buffer zone (or zones)
 It is a zone which is clearly delineated and which surrounds
or is contiguous to the core area.
 Activities are organized here so that they do not hinder the
conservation objectives of the core area but rather help to
protect it
 It can be an area for experimental research, for example
- to discover ways to manage natural vegetation, croplands,
forests, fisheries,
- to enhance high quality production while conserving natural
processes and biodiversity, including soil resources, to the
maximum extent possible.
- to explore how to rehabilitate degraded areas.
 It may accommodate education, training, tourism and
recreation facilities.

Zones of a Biosphere
Reserve
The Transition Area:
 The Transition Zone is the outermost part of a Biosphere Reserve.
 This is usually not delimited one and is a zone of cooperation where
conservation, knowledge and management skills are applied and
uses are managed in harmony with the purpose of the Biosphere
Reserve.
 This includes settlements, crop lands, managed forests and area for
intensive recreation, and other economic uses characteristic of the
region.
 In Buffer Zone and the Transition Zones,
- Manipulative macro-management practices are used.
- Experimental research areas are used for understanding the
patterns and processes in the ecosystem.
- Modified or degraded landscapes are included as rehabilitation
areas to restore the ecology in a way that it returns to sustainable
productivity.

Essential Features of Biosphere
Reserves
Biosphere reserves cover the great variety of natural areas of the biosphere,
going
from high mountains to greatly human-impacted plains, from coastal regions
and islands
to vast inland forests, from the deserts of the tropics to the tundra of the polar
regions.
To qualify for designation as a biosphere reserve, an area should normally:
 be representative of a major biogeographic region, including a gradation of
human intervention in these systems;
 contain landscapes, ecosystems or animal and plant species, or varieties
which need to be conserved;
 provide an opportunity to explore and demonstrate approaches to
sustainable development within the larger region where they are located;
 be of an appropriate size to serve the three functions of biosphere reserves
mentioned above;
 have an appropriate zoning system, with a legally constituted core area or
areas, devoted to long-term protection; a clearly identified buffer zone or
zones and an outer transition area

Biosphere Reserves: Indian approach
National Biosphere Reserve Programme
The national Biosphere Reserve Programme was initiated in 1986 and its aims
and
objectives are as follows:
Aims of the Scheme
 To serve as wider base for conservation of entire range of living resources
and their ecological foundations in addition to already established protected
area network system
 To bring out representative ecosystems under conservation and sustainable
use on a long term basis.
 To ensure participation of local inhabitants for effective management and
devise means of improving livelihood of the local inhabitants through
sustainable use.
 To integrate scientific research with traditional knowledge of conservation,
education and training as a part of the overall management of BR.
The Core Advisory Group of Experts, constituted by Indian National MAB
Committee
identified and prepared a preliminary inventory of 14 potential sites for
recognition as
BRs in 1979. Subsequently additional BR sites were proposed by the National

Biosphere Reserves: Indian
approach
Objectives
It may be noted that BRs are not a substitute or alternative, but a re-
enforcement to the
existing protected areas. The objectives of the Biosphere Reserve programme,
as
envisaged by the Core Group of Experts, are as follows:
 To conserve the diversity and integrity of plants and animals within natural
ecosystems;
 To safeguard genetic diversity of species on which their continuing
evolution depends;
 To provide areas for multi-faceted research and monitoring;
 To provide facilities for education and training; and
 To ensure sustainable use of natural resources through most appropriate
technology for improvement of economic well-being of the local people.
These objectives should be oriented in such a way that the BRs are the Units
wherein the
Biological, socio-economic and cultural dimension of conservation are
integrated
together into a realistic conservation strategy.

Criteria for selection of
Biosphere Reserves in India
Primary criteria
 A site that must contain an effectively protected and minimally
disturbed core area of value of nature conservation and
should include additional land and water suitable for research
and demonstration of sustainable methods of research and
management.
 The core area should be typical of a biogeographical unit and
large enough to sustain viable populations representing all
tropic levels in the ecosystem.
Secondary criteria
 Areas having rare and endangered species
 Areas having diversity of soil and micro-climatic conditions
and indigenous varieties of biota.
 Areas potential for preservation of traditional tribal or rural
modes of living for harmonious use of environment.

How are Biosphere Reserves
designated in India?
 At the initiative of the central/state governments,
detailed study is carried out and a project report is
prepared by the concerned state following the criteria
adopted for designation of BRs.
 The land and forest being the state concerns, the
respective state governments have to agree to
designate the identified area as Biosphere Reserve.
 The Central Govt. provides financial assistance for
management and research activities in these BRs.
 The Management of Biosphere Reserves is the
responsibility of the concerned State/UT with
necessary technical input and training facilities
provided by the Central Government.
