Asian Water Summit Ends In Dispute; Action needed

Asian Water Summit Ends In Dispute

This is disappointing news. For all of my reporting here on the global water crisis about predictions of increased scarcity by 2030-2050, I always in the back of my mind believed that water disputes were actually in the end the one dispute that could and would be worked out amicably... as in MAD regarding nuclear issues where both sides have nukes therefore neither side strikes because they know it would only bring about their own demise.

Such is the situation with water. It is kind of like, MAWD... mutually assured water destruction. Countries must learn to mediate diplomatically regarding the crucial water issues such as freshwater resources now becoming scarcer in light of population growth, climate change, waste, pollution, and privitization. To do otherwise would only wind up destroying their own ecosystems and social structures. I fear however, that with so many issues …

Life cycle assessments measure water's impact on Earth's ecosystems for first time

The damages to ecological systems from overconsumption of water are illustrated in this world map (yellow represents low impacts, navy high impacts).

Despite water’s significance, modeling how freshwater consumption for drinking, industrial manufacturing, and agriculture has affected ecosystems, human health, and the depletion of nonrenewable freshwater resources has been overlooked. In a new ES&T study (DOI 10.1021/es802423e), researchers take the traditional life-cycle assessment (LCA) approach one huge step beyond current practices with a model that incorporates water consumption.LCA models were created to address problems in industrialized nations, and most of these countries don’t experience human-health risks due to water scarcity, the authors note. Recently,…
