Global warming necessitates new approach to ecosystem restoration, say scientists
Washington | June 15, 2006 2:19:54 PM IST
Ecological scientists have warned that the phenomenon of global warming may warrant new approaches to ecosystem restoration, and that restoration methods of the past may not always be applicable in the future. In an article published in the June issue of Restoration Ecology, they write thatecosystems often behave in volatile ways, and because of which restoration ecologists are often faced with unforeseen challenges. They said that the largest potential challenge ahead is to restore environments undergoing the most rapid rate of change in the earth's history. This global climate change, they say, is likely to have important regional consequences for biota and ecosystems. Ecological restoration, including reforestation and rehabilitation of degraded land, may be a common response to the effects of climate change, but the implications of this changing environment must be considered, they opine. Using past ecosystem conditions as targets and references may be ineffective under new conditions, they conclude, adding that in addition, there may be less support in the future for longer-term, traditional restoration projects.
