Question

ecotechnology is important in development describe for 5marks

Answer 1

Ecotechnology is defined as the use of technological means for ecosystem management based on deep understanding of principles on which natural ecological systems are built and on the transfer of such principles into ecosystem management in a way to minimize the costs of the measures and their harm to the global environment. Seven basic ecosystem principles are outlined in agreement with Jørgensen (1992; Ecol. Modelling, 62: 1–27). Basic rules of ecotechnology are derived from these ecosystem principles. As the rules are fairly general, the implementation of these ecotechnological rules for ecosystem management is given. Some applications of the general rules particularly as related to watershed and regional management are specified. Examples of ecotechniques used for watershed and lake/reservoir management are given. It is shown that to be effective in the ecotechnological sense the ecotechniques have to be used in particular instances with the help of mathematical optimization models. Such models are constructed to select a combination of the options which result, for the given ecosystem situation, in least cost and least secondary harm to the global environment.
