Man and the Biosphere Programme (MAB)

The Man and the Biosphere Programme (MAB) is a program run by the United Nations Educational, Scientific and Cultural Organization (UNESCO). The program helps improve the relationship between humans and nature and teaches humans to use environmental resources in the most sustainable ways possible. The MAB attempts to reach these goals by designating particular areas as biosphere reserves. The reserves are places where conservation, learning, research, and ecologically sound human development all take place. UNESCO works with local populations to maintain these biosphere reserves. The program also conducts research to improve human understanding of the environment and to develop ways for humans to be more sustainable in their business practices and personal lives.

Background

Humanity has always had a unique relationship with nature. Humans are a part of nature, but they also influence nature in many more ways than most other organisms. People have tried to control and shape nature throughout human history. As humans developed new technology, from the wheel to the metal plow to the combustion engine, people have continued to change the environment in ever-increasing ways. For example, the Industrial Revolution brought new machines and technologies that humans used to shape their world. Humans have high-rise buildings, solid road surfaces, and vehicles—all of which affect the environment.

Climate scientists agree that human technology, which is powered mostly by fossil fuels, has contributed to climate change. Human development has contributed to habitat loss for plants and animals. Trade and travel have spread invasive species to different parts of the world. All these effects change the environment. The UNESCO MAB is meant to study the relationship between humans and nature, and to preserve some of the important natural habitats on Earth.

Overview

In 1971, UNESCO sought to find a way to improve the relationship between humans and nature. The result was the MAB Programme. The main way that the MAB protects specific biospheres is by naming biosphere reserves. The biosphere reserves are meant to protect especially important and fragile parts of nature. All ecosystems—including mountain, marine, coastal, forest, urban, and savannah ecosystems—around the world have been named as protected biosphere reserves. Although biosphere reserves are protected areas, people are still allowed and encouraged to use the land. Furthermore, businesses are still able to develop in certain parts of biosphere reserves. The point of the biosphere reserves is not simply to conserve the ecosystems; they are meant to improve the relationship between humans and the environment. So, the reserves are meant to help people learn to live more sustainably while still enjoying nature and using its resources. UNESCO says that the reserves are meant to act as places where people can learn sustainable practices. Another goal of the biosphere reserves is to maintain an area’s cultural practices.

Each biosphere reserve has three parts. The main part of the reserve is meant strictly for conservation. It is not used for development, and it is meant to preserve the fragile natural habitat. The next part of the reserve is a buffer zone around the conservation land. This zone is often used for research, learning, and scientific monitoring. The third part, the transition zone, is outside the buffer zone. This is the part of the land where the most human activity takes place. The transition zone is also where people can create businesses that are socially and ecologically sustainable.

The International Coordinating Council of the MAB Programme is the main governing body of the program and designates new biosphere reserves. In this capacity, the council recommends research projects, coordinates international cooperation among member states, and consults with nongovernmental organizations on scientific and technical questions.

The biosphere reserves are nominated by the countries in which they exist. Furthermore, the countries or states that own the areas maintain sovereignty over the biosphere reserves. By 2025, 784 sites existed across 142 countries. The first biosphere reserves were named in the 1970s, and new reserves are added regularly. Sometimes, countries request that the biosphere reserve designation be removed from particular pieces of land. For example, in 2017, the United States requested the withdrawal of seventeen reserves. Although withdrawals are uncommon, they may happen when sites no longer meet the network’s requirements, including the presence of resident communities in the transition area.

One of the main focuses of the program is to promote sustainability through conservation in the biosphere reserves. Another focus of the program is to study the relationship between humans and the environment. The program identifies the way human activities affect the environment. It examines how human interaction affects biospheres, and it examines systematic effects of human behavior. The program also studies the ways changes in nature affect humans. For example, human actions have contributed to a loss of biodiversity. Research done on the biosphere reserves tells scientists more about how such changes affect humans.

Some of the areas identified as biosphere reserves have benefited from MAB. One of the most apparent benefits is the protection of the biosphere and the animals and plants that live inside it. Another benefit is the development of sustainable businesses and organizations in the biosphere reserves. For example, many biosphere reserves become popular tourist destinations, and the people who live in the reserve can benefit from the economic growth brought by tourism.
