Changes in those policies, including their financing components, can in many cases facilitate reductions of water management costs. Assessing these perverse support mechanisms, with a view to phasing them out, can contribute to lowering the cost of water resources management. Efforts in this direction are ongoing in OECD countries, but more could be done: some 50% (2008-10) of total OECD agricultural producer support provides incentives to produce and/or use variable inputs, compared to 85% in 1986-88 (OECD, 2012b). The EU Water Framework Directive has stressed the importance of analysing the financing linked to sector policies (e.g. agriculture, energy or climate change) that directly support projects and actions that impact on the water system.
