Book excerpt: It is clear that more sustainable and efficient use of fresh water resources will become crucial in future global water management to avoid major threats to biological life. Trade in Water Under International Law offers a careful and well-reasoned introduction and analysis of this emerging and largely unchartered subject of international trade law, which has hitherto been of key importance in domestic law and policy, exploring the potential and limits of addressing the use of water resources in the context of World Trade Organization law.
