AbstractEcological economics is an emerging field that offers significant room for creativity and innovation at the conceptual level on how to operationalize sustainability. It integrates economics with ecology and many elements from both the natural and social sciences to provide an integrated perspective on environment-economy interactions. A major policy dilemma that ecological economics addresses is how policy-makers can influence markets, so that they receive the 'right' signals from the na...

AbstractOne of the basic principles in the European policy to cope with the growing challenge of water scarcity is that water demand management should be considered before opting for additional water infrastructure. The implication of this is that water must be treated as an economic good, which means that the "user's pays' principle"has to be implemented. At the same time there is much political consensus that the water price has to be "equitable". Water can be subsidized without violating the ...
