MAB – an environmentally sustainable initiative
MAB combines the natural and social sciences, economics and education to improve human livelihoods and the equitable sharing of benefits, and to safeguard natural and managed ecosystems, thus promoting innovative approaches to economic development that are socially and culturally appropriate, and environmentally sustainable.
It predicts the consequences of today’s actions on tomorrow’s world and thereby increases people’s ability to efficiently manage natural resources for the well-being of both human populations and the environment.
Objectives of MAB
1 . Identify and assess the changes in the biosphere resulting from human and natural activities and the effects of these changes on humans and the environment, in particular in the context of climate change.
2 . Study and compare the dynamic interrelationships between natural/near-natural ecosystems and socio-economic processes, in particular in the context of accelerated loss of biological and cultural diversity with unexpected consequences that impact the ability of ecosystems to continue to provide services critical for human well-being.
3 . Ensure basic human welfare and a liveable environment in the context of rapid urbanization and energy consumption as drivers of environmental change.
4 . Promote the exchange and transfer of knowledge on environmental problems and solutions, and to foster environmental education for sustainable development.
Structure of Biosphere Reserve under MAB
Biosphere reserves have three interrelated zones that aim to fulfil three complementary and mutually reinforcing functions:
1 . The core area(s) comprises a strictly protected ecosystem that contributes to the conservation of landscapes, ecosystems, species and genetic variation.
2 . The buffer zone surrounds or adjoins the core areas, and is used for activities compatible with sound ecological practices that can reinforce scientific research, monitoring, training and education.
3 . The transition area is the part of the reserve where the greatest activity is allowed, fostering economic and human development that is socio-culturally and ecologically sustainable.
World Network of Biosphere Reserves
Its World Network of Biosphere Reserves currently counts 669 sites in 120 countries all over the world, including 20 transboundary sites.
