IDIAS-A Tool for Analysis and Monitoring of Direct and Indirect Effects of Interdependent Interventions in IRBM--An Example from Pahang River, Malaysia
Integrated management and inter-disciplinary assessment (IDA) are ambiguous terms often used in planning of water management and urban/rural development strategies and projects. These terms generally represent an attempt to evaluate the environmental and/or socio-economical effects of various management interventions in one or more sectors, and in neighbouring catchments. Some tools and procedures for environmental impact assessments (or strategic environmental assessments) have been broadly used for evaluation of the environmental effects of a set of management/project scenarios in connection with policy development and project implementation. These tools, however, separately assess the effects on different sectors from a planned project or a set of policy/development strategies and management actions. The inter-sectoral (or multi-disciplinary) relationships are seldom addressed quantitatively due to the complexity of the procedure and lack of data/information. It is necessary to ensure some degree of transparency in the process from decision-making, planning to implementation, monitoring and follow-up. Hence, a systematic approach is required in the otherwise generally qualitative assessment and evaluation of impacts where the cause-effect relationships are mutually interdependent. IDAs need to be reassessed with the passage of time, and data therein should be open to scrutiny and revision as new data become available. The paper will discuss various aspects of how to make IDA operational in river basin management and design/implementation of monitoring programmes. A decision support tool (Inter-Disciplinary Impact Assessment System-IDIAS), which incorporates the above specifications, is presently being developed. The IDA-methodology presented is based on experiences gained during a number of concrete river basin management projects/programmes. A simplified example from Pabang River in Malaysia is used to illustrate the principles and procedures of the IDIAS. In Pahang River the objective was: ① to establish plans and policies of how to develop the downstream part of the river; considering the prevailing socio-economic setting (fishery, environmental constraints, infrastructure, flood protection); ② to assess the inter-disciplinary effects of a number of proposed project options.
