A biosphere reserve is a protected area established to conserve biodiversity, promote sustainable development, and support research, education, and the well-being of local communities. Created under UNESCO's Man and the Biosphere (MAB) Programme, these reserves serve as model regions where the relationship between people and nature is carefully managed and studied.
Purpose: Biosphere reserves aim to integrate ecosystem conservation with human development. They provide a framework for balancing the protection of biodiversity with economic, cultural, and social needs.
The zonation system developed for Baa Atoll has adopted the UNESCO World Biosphere Reserve zonation criteria and protocols. This includes a three-tiered zonation approach. Each biosphere reserve is organized into three interconnected zones, each with a distinct role:
A strictly protected zone dedicated to conserving landscapes, ecosystems, species, and genetic diversity. Human activity is highly limited to ensure long-term ecological integrity.
Core Areas are clearly defined management areas that have a high ecological significance in terms of marine and terrestrial biodiversity, have a high natural value to Baa Atoll, the nation and to the communities who use the atoll resources. Core Areas are allocated the highest levels of conservation to ensure the natural ecological systems and organisms are fully protected.
Key management objectives include:
All Core Areas prohibit the commercial, artisanal and subsistence extraction of all biological and non-biological resources. However, certain activities (e.g. tourism and picnics) and uses can be allowed if these activities are consistent with the Core Areas conservation objectives. These activities require stringent management systems, codes of conduct and due diligence from all users to ensure the goals of Core Areas are achieved.
All anchoring of any boat (unless in an emergency) is prohibited. The boundary for all Core Areas extends 100 metres from the reef edge and includes all marine and terrestrial biological and non-biological resources enclosed within the boundary.
Surrounding or adjoining the core area, this zone allows activities compatible with sound ecological principles. It is used for scientific research, monitoring, training, and environmental education.
Buffer zones are defined management areas that by definition (UNESCO) provide conservation and protection support services for Core Areas that maximise biological connectivity whilst allowing the communities and atoll users access to appreciate and enjoy these zones. These areas in their own capacity have a high ecological significance in terms of marine and terrestrial biodiversity, ecosystem functions and have a high natural value to Baa Atoll.
Key management objectives include:
Buffer Zones prohibit the commercial extraction of all biological and non-biological resources. However, can provide for a range of artisanal and subsistence extractive and non-extractive activities that are compatible with the Core Area conservation objectives. Tourism (e.g. diving, snorkelling) and public access (e.g. picnics) to buffer areas for recreational purposes that are non-extractive are permitted. These activities require stringent management systems, codes of conduct and due diligence from all users to ensure the goals of this zone are achieved.
All anchoring of any boat (unless in an emergency) on reef associated bottom substrate is prohibited. Anchoring on sand is permitted. The boundary for each Buffer Zone has been developed through a consultative process with stakeholders and has been specially designed to accommodate its supporting function of the Core Area. Therefore, the sizes of buffer zones vary and include all marine and terrestrial biological and non-biological resources enclosed within the boundary. All atoll wide bans and management restrictions detailed in the BACP are applicable to all Buffer Zones.
The outermost zone where local communities, organizations, and stakeholders engage in socio-culturally and environmentally sustainable economic activities. This area serves as a space for innovation and practical sustainability initiatives.
Transition Areas are defined management areas that provide for long term sustainable resource (biological and non-biological) utilisation and livelihood activities (commercial, artisanal and subsistence) whilst ensuring these resources are conserved through an integrated ecosystem management programme. Transitional Areas have a long history of economic and traditional interaction with people and form the basis of communities in Baa Atoll. These areas in their own capacity have ecological significance in terms of marine and terrestrial biodiversity, ecosystem functions and natural value to Baa Atoll.
Key management objectives include:
Transition Areas are the least restrictive management zone allowing most reasonable uses of biological and non-biological resource extraction (commercial, artisanal and subsistence) and use. All activities require management systems, codes of conduct and due diligence from all users to ensure the goals of this zone are achieved. All anchoring of any boat (unless in an emergency) on reef associated bottom substrate is prohibited. Anchoring on sand is permitted.
The Transition Area boundary includes all areas and resources (biological and non-biological) within Baa Atoll that are outside Buffer Zones and Core Areas and extends 1 nautical mile from the outer reefs of the atoll. The Transitional Area has been developed through a consultative process with stakeholders and has been specially designed to provide supporting functions to the Buffer Zones and Core Area whilst ensuring sustainable livelihood activities can be undertaken.
Biosphere reserves are often described as "learning places for sustainable development." They serve as testing grounds for interdisciplinary approaches that address interactions between social and ecological systems, including conflict prevention and biodiversity management. By encouraging sustainable use of natural resources—such as responsible fishing, forestry, and agriculture—biosphere reserves help ensure that development proceeds without compromising ecosystem health.
These reserves may include terrestrial, marine, and coastal ecosystems, and each site contributes local solutions to global environmental challenges.
UNESCO (the United Nations Educational, Scientific and Cultural Organisation) coordinates a world network of over 500 Biosphere Reserves in 105 countries. These are sites recognized under UNESCO's Man and the Biosphere Programme, which innovate and demonstrate approaches to conservation and sustainable development.
World Biosphere Reserves are places where conservation, research and development successfully interconnect. They integrate biological and cultural diversity, combining core protected areas with zones where sustainable development – and innovative approaches to it – are fostered, tested and developed by locals and enterprises alike.
Biosphere reserves are proposed by national governments and reviewed under the MAB designation process. Final approval is given by the Director-General of UNESCO based on recommendations from the MAB International Coordinating Council (MAB-ICC). Once designated, they form part of the World Network of Biosphere Reserves, an internationally recognized collection of sites committed to advancing sustainable development worldwide.
