Modelling current and future supply and water demand in the northern region of the Seybouse Valley

Abstract

Water in the Seybouse River basin is getting scarce, yet it is the key to its economic development. A fast growing population, expanding agricultural and industrial sectors and the impacts of climate variability, create demands for new water sources and innovative management of water resources and services. The object of this study is the water resources management in the lower Seybouse basin characterized by a steady increase of water demand to meet different uses. This study takes into account changes in water demand of different urban, agricultural and industrial supply process. Our approach is to integrate data in WEAP modelling software to simulate current and future water balance and then to analyse the situation of water in different scenarios, socio-economic development and climate change to 2050. This software is based on the representation of the feeding system in a form of the network of water demand and supply. Our findings reveal the vulnerability of the region in its ability to the pressures resulting from the increase of needs of different sectors at the horizon of the forecasted period. They also indicate the need for larger mobilization of new resources into the system and lay the foundations for a sustainable water policy in the northern region of the Seybouse valley.

Integrated water resource management for mega city: a case study of Dhaka city, Bangladesh / Zintegrowane zarządzanie zasobami wodnymi dużych miast: przykład miasta Dakka w Bangladeszu

Abstract

Dhaka the capital of Bangladesh is facing a serious water scarcity problem due to the big gap between demand and supply of water system. When accelerating water scarcities and pollution in and around urban centers are superimposed on issues like continuing urbanization, lack of investment funds for constructing and maintaining water infrastructures, high public debts, inefficient resources allocation processes, inadequate management capacities, poor governance, inappropriate institutional frameworks and inadequate legal and regulatory regimes, water management in the megacities poses a daunting task in the future. To overcome these water related problems, water can be a designing element for structuring future development with the combination of sustainable approaches for social and physical transformation, open up opportunities for water management system. Therefore an integrated approach like integrated water resource management (IWRM) system is required that responds to problems that are all interrelated. Alternate supply and demand management tools such as ground water recharge, rainwater harvesting, effective water pricing, reclaimed water use are suggested to meet the deficit of current supply system through the efficient use of the scarce resources available. Institutional reform and improved water planning are required to facilitate economic growth and social development. Finally, human resource development is identified as key factor for the sustainable effective management of this valuable resource.
