A development and environmental policy action programme for the 21st century, as well as a guiding document for sustainable development, which was adopted by 179 states at the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro in 1992. In the meantime, Agenda 21 has become a guideline for public action. It comprises the four thematic areas of social and economic dimensions, conservation and management of resources for development, empowerment of major groups, and ways of implementation. One of the many sub-areas deals with the conservation of ancient crops, including grape varieties. See also under decarbonisation, globalisation, climate change, greenhouse effect, world heritage, pollution and wild vines.
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
