The geographical divisions of the environmental problems are:
(i) Local problem: An environmental problem which affects only a particular place or a small area so far as their genesis and spread are concerned is called a local environmental problem. e.g. land pollution created by a small-scale industry, water scarcity in winter due to shallowing of wetlands, bank erosion caused by a local river, etc.
(ii) Regional problem: Regional problem exists in a large region or in one or more nations. e.g. flood problem in the state of Assam as a result of the overflooding of the Brahmaputra or the Barak rivers, water pollution in a vast industrial area, scarcity of underground water in a city, soil erosion in a river basin, etc.
(iii) Global problem: The environmental issues that affect the entire world are termed as global problems. These problems need international efforts for solution and management. e.g. global warming which affects the atmosphere and thus has no geographical boundary.
