SustainabilitySustainability is seen as a guiding principle for development, and means that all aspects of development (social, economic and environmental) should be able to be maintained for future generations. As these aspects are all interlinked, unsustainable development of any one aspect will affect the other aspects. So, for example, over-logging of a forest means not only will the forest be much degraded and diminished, but that the next generation will be unable to gain as much benefit from its goods and services (there will be very little more timber to harvest, and forest may be unable to protect the watershed).
Sustainable development is most commonly defined as that which:
The Present Situation
Unfortunately, although ecosystems are vital for human life on earth, most have been seriously degraded or used unsustainably, and the distribution of species across the world is becoming more homogenous as the diversity of plants and animals is reduced and alien species become invasive. The degradation of ecosystems needs to be reversed through changes in policy and practice if they are to meet the coming decades' increasing demand for food, drinking water, timber and fibre.
Sustainability - a Theme in Policies
The sustainable use of biological diversity is a recurring theme in the CBD and one of its primary objectives (Articles 8 and 10), as well as in support of the Millennium Development Goals to alleviate poverty. Biodiversity contributes to poverty reduction by improving the nutrition and health of the poorest people in the world, generating incomes and stabilising ecosystems services (e.g. generation of water, cycling of nutrients, prevention of erosion) on which the people depend.
For wealthy nations, sustainable development also depends on the conservation and management of ecosystems which supply essential services and exploring ways to increase production (e.g. food, fibre and other minor crops) while using renewable and non-polluting sources of energy and other resources.
The Role of Botanic Gardens
Botanic gardens are addressing sustainability issues in several ways. This presentation on sustainability and botanic gardens (PPT, 3.6MB) outlines some of the issues to consider. The articles below illustrate the contribution of botanic gardens to:
Plants for Life: Medicinal Plants Under Threat
BGCI has published the findings of a year-long investigation into the state of medicinal plants around the world.
Education for Sustainable Development – Guidelines for Action in Botanic Gardens
BGCI has published Guidelines on Education for Sustainable Development. Suitable for those working in botanic gardens and other site-based education centres, it features tips and case studies from botanic gardens around the world. The Guidelines are freely available to all in PDF and printed format.
Sustainable Plant Use in Africa
Cultivate, BGCI's regular e-bulletin brings you opinion, comment, case studies and surveys for and about the world's botanic gardens. Sign up today - click the link.
Biodiversity and the Precautionary Principle: Risk and Uncertainty in Conservation and Sustainable Use (Dickson & Cooney, 2005)
The Precautionary Principle entails acting to avoid serious or irreversible environmental harm, despite lack of scientific certainty. This book is the first to examine its application to conservation and biodiversity management, studying impact on both natural resources and livelihoods.
