Looking for definitions for various topics related to environmental governance

As part of working on subject of environmental governance, I came across these terms, globalization, decentralization, market and individual incentives-based governance, and cross-scale governance. The source gave me a rather lengthy discussions but what I am looking for is some simple definitions. During my search, I was not able find any thing. Maybe someone could help. Also, are these terms really that important to be part of the discussion. Do these terms help define what environmental governance is? Please explain. Thanks for your help.
