Interdisciplinary research is ‘an integration and synthesis of ideas and methods to advance fundamental understanding or to solve problems’ Interdisciplinary research is focused on the integration of concepts, techniques and/or data (Porter et al., 2006). Generally, interdisciplinary is not a simple heterogeneity but it is a scientific complexity of discipline, concepts, techniques and methods to solve or to deal with problems (Council, 2004, Council, 2000, Porter et al., 2006).Interdisciplinary is essential in environmental science. The causes of deterioration or improvement of an environment are not completely understandable by mono-disciplinary research but they needs to build better knowledge integration, collaboration and working in an interdisciplinary research approach(Ostrom, 2007). Integration and implementation of sciences are effective ways to tackle complex societal problems (Bammer, 2003).
A watershed is commonly defined as a topographically delineated area in which all water drains to a common point (Wang, 2001).Watershed program is a land based program focused on water. It has an objective to enhance agricultural productivity through increased moisture conservation and protective irrigation for socio-economic development of rural people. (Joshi et al., 2004). Integrated watershed management is one of the methods to work on environmental improvements. Integrated watershed management is a collection of target points that linked disciplines (Karageorgis et al., 2005). However, in many cases interdisciplinary watershed management lacks practical applicability. My proposition is in developing countries integrated watershed management is not actually an interdisciplinary project approach. Therefore, the objective of this essay is to argue on watershed management should plan and implement in an interdisciplinary approach.
Watershed management in Ethiopia during planning phase
Watershed management is a set of interlinked activities that needs an integration of institutional and organization arrangements (Dixon and Easter, 1991). This allows the watershed program comprise the technical and biological, water and soil conservation practices. In addition, there is delineation of the field where the program can take placed. Therefore, integrated watershed management bridges the ecological, agricultural engineering, geography and GIS disciplines. However, in developing country losses this interdisciplinary. In developing country, watershed management not to be interdisciplinary starts from their perception. They consider as deterioration of land and water resources or a management task for a specific resource such as forest (Dixon and Easter, 1991). In Ethiopia, the watershed management program in the planning phase is governed only by one discipline, such as soil and water conservation experts. These shows starting from planning phase the watershed management project aligned to the knowledge of ecology which is not integration of...
