Introduction to the Ecological approach
Chapter 6 introduces the Ecological approach to rivers that arose in response to the adverse effects of the Commercial approach. It explains the distinction between the pre- and post-industrial Ecological approaches. While the former was a compulsion due to low level of technology, the latter is a choice made to avoid the negative consequences of high level of technology acquired through the Industrial Revolution. The chapter clarifies the relationship of the Ecological approach with the basin-wide approach to rivers. It also shows that the Ecological approach can be viwed as an enlightened anthropocentric view of river, which in practical terms is also compatible with the non-anthropocentric view. The chapter goes on to show that, contrary to the popular perception, the Ecological approach is an active approach, requiring sustained efforts along multiple directions. Instead of negating the role of rivers as a resource, the Ecological approach advocates the use of this resource while preserving the basic role of rivers in maintaining earth’s hydrological cycle and the unique ecologies of their basins. The Ecological approach thereby is more conducive to sustainable development than the Commercial approach.
