Another group of movements are those involved in struggles against mega-dams. In every country where a mega-dam is being built, one is likely to find an environmental movement opposing it. Increasingly antidam movements are pro-river movements for more sustainable and equitable management of river systems and valleys. The early 1980s saw the first anti-dam movement launched in the North, namely, the campaign to save the Franklin River and its surrounding forests in Australia. This was a wilderness and forest campaign as well as anti-dam campaign. At present, there has been a spurt in mega-dam building in the South, from Turkey to Thailand to South Africa, from Indonesia to China. India has had some of the leading anti-dam, pro-river movements. Narmada Bachao Andolan is one of the best known of these movements. It is significant to note that, in anti-dam and other environmental movements in India, the most important shared idea is non-violence.
