DPSIR (Drivers, Pressures, State, Impact, Response) Model-recognizes the human activities which place pressure on the Environment and how these pressures modify the current state of the atmosphere, hydrosphere, lithosphere and biosphere. This leads to impacts on the environment as well as on social and economic systems. In tum, human society attempts to problem-solve in order to remove, reduce or prevent the drivers and pressures, restore the state of the environment and mitigate impacts.
