when was the term sustainable development first used
Sustainable development In 1980 the International Union for the Conservation of Nature published a world conservation strategy that included one of the first references to sustainable development as a global priority[7] and introduced the term "sustainable development".[8] Two years later, the United Nations World Charter for Nature raised five principles of conservation by which human conduct affecting nature is to be guided and judged.[9] In 1987 the United Nations World Commission on Environment and Development released the report Our Common Future, commonly called the Brundtland Report. The report included what is now one of the most widely recognised definitions of sustainable development.[10][11]
Ecosystem management The term natural resource management is frequently used when dealing with a particular resource for human use rather than managing the whole ecosystem.[28] A main objective of natural resources management is the sustainability for future generations, which appoints ecosystem managers to balance natural resources exploitation and conservation over long-term timeframe.[29] The balanced relationship of each resource in an ecosystem is subject to change at different spatial and temporal scales.[30] Dimensions such as, watersheds, soils, flora and fauna, need to be considered individually and on a landscape level. A variety of natural resources are utilized for food, medicine, energy and shelter.[31]
