land development puts more emphasis on the expected economic development as a result of the process; "land conversion" tries to focus on the general physical and biological aspects of the land use change. "land improvement" in the economic sense can often lead to land degradation from the ecological perspective. land development and the change in land value does not usually take into account changes in the ecology of the developed area. while conversion of (rural) land with a vegetation carpet to building land may result in a rise in economic growth and rising land prices, the irreversibility of lost flora and fauna because of habitat destruction, the loss of ecosystem services and resulting decline in environmental value is only considered "a priori" in environmental full-cost accounting.
