“…WEAP21 was developed by the Stockholm Environmental Institute, USA. WEAP21 is a surface and ground water tool based on water balance accounting principles, which can test alternative sets of supply and demand conditions [13]. It integrates a range of physical hydrologic processes with the management of demands and installed infrastructure in a seamless and coherent manner [14].…”

“…It is designed for comparative analysis where a base case (scenario) is developed and then alternative scenarios are created and compared to the base scenario. It is useful for what-if analysis of various policy scenarios and long range planning studies [13]. It provides a platform for detailed modelling of water demand management strategies of the various water sectors (e.g.…”

Integrated water resources management (IWRM) is being embraced by many countries. Kenya is implementing a new water policy formulated along IWRM principles. The newly formed river basin organisations grapple with issues of sustainability, water allocation, resource quality objectives, equity, environmental flows among others. Kenya experiences water scarcity and stress. This research applied the Water Evaluation and Planning System (WEAP21) model to test a systems approach in evaluating the impact of changes in water policy and water development in Perkerra catchment in Kenya. The upper catchment has humid to semi-humid climatic conditions while the lower catchment experiences semi-arid to arid climatic conditions. Biophysical and human interventions were modelled in WEAP21. The scenarios analysed the impact of the new water policy of equitable water allocation, maintaining the reserve and ecological flows. The impact of increasing water storage and irrigation efficiency was evaluated. The reference scenario was validated using flows at the catchment observation station 2EE7B. The Tennant method was used to determine minimum environmental flows. From the analyses, one dam project will reduce water deficit by 5%. However, higher irrigation efficiency reduces the deficit by 15%. The implementation of two dam projects improves

Abstract:Water scarcity problems are becoming increasingly common due to higher water demand, urbanization, economic development and climatic variability. Policies and measures based on Integrated Water Resources Management (IWRM) are often advocated to tackle the problems of competing demands and conflicts among stakeholders. Demand management measures as part of the IWRM package are expected to offset the increased demands on water resources caused by economic growth. However, even if IWRM-based policies are in place, the potential impacts of demand management are seldom quantified while formulating water policies or development plans. To address this, we conducted scenario analysis using Water Evaluation and Planning System (WEAP21) in a case study from the Awash Basin in Ethiopia. We show that ambitious irrigation expansion plans to combat food insecurity will lead to overexploitation of water resources with increasing inequity between smallholders and commercial farmers. Demand management measures proposed by water users are insufficient to offset these consequences. Potential demand measures that are embedded in the IWRM-based policies alone are also insufficient. While water policies emphasize IWRM principles but do not indicate how to properly implement them, economic development plans are often launched without adequately considering equity and environment, two of the three pillars of IWRM. This scenario analysis shows the importance of quantitative information in IWRM formulation and monitoring.

“…Its aim was to create a generic river basin management decision support system and it is based on a system of simulations of river network flows and reservoir operations (Assaf et al, 2008). It has been linked with stream-aquifer models for the analysis of the combined use of groundwater and surface water resources.…”

The observed area covers Germany and Austria up to 2025. Since the main effects of climate change in this region are expected to be caused through changes in the watercycle, we place a special focus on the exemplary region of the upper Danube catchment area. Industry is the main regional user of water resources. Water is an essential production factor and is used in almost every production process of a manufactured good. We apply estimates of regional production functions, based on AFiD-panel micro-data for Germany, to calibrate regional industrial production and water usage within DANUBIA. Thus, we are able to simulate region-specific effects of climate change and the impact of social scenarios using an unprecedented model of reciprocal influences of a huge network of interdisciplinary research areas. Simulation results show wide regional differences in production site reactions as well as between differing scenarios. Comparing scenarios of moderate and serious climate change, we are able to illustrate the severe environmental effects in some regions and to determine considerable economic effects on regional economic growth.
