Integrated Urban Water Management (IUWM) has emerged in the past two decades as a promising approach to the application of Integrated Water Resources Management (IWRM) principles at the city-level. IUWM is expected to contribute to the achievement of multiple policy objectives, often including increased water security. This paper uses a case-based approach to study the impact of IUWM on water security, focusing on the influence of the level of institutionalization of IUWM within water governance at the city-level. Process tracing is applied to the cases of Singapore and Hong Kong, in which IUWM has been adopted but implementation and outcomes have diverged. We find that the depth of institutionalization, a difference between the two cases identified at the outset, has contributed to the achievement of better water security outcomes in Singapore as it has facilitated the development and implementation of a more far-reaching strategy. A supportive governance framework appears to amplify the impact of IUWM on progress towards water security and other policy targets.

According to the latest government reports, India is facing evident shortfall of water in various parts of the country, and Himalayan states are likely to suffer the impacts of climate change related to water more than non-Himalayan states. Water resources are expected to affect Gross Domestic Product (GDP) of the country, and future projections are far more upsetting. In this light, sustainable and adaptive strategies such as integrated water resources management, nature-based solutions have been promoted globally for sustainable and integrated urban water management. The paper inquires into functions of respective institutions and their possibilities to adopt possible nature-based solutions such as rain water harvesting in response to water insecurity and adaptation in times of climate change. Taking case of Haldwani city, the paper assesses water demand and supply gaps, the existing water institutions, their scope of work and water management mechanism. Further, the scope of adoption of possible nature-based solution is explored by the purview of their work in water management. This was derived through an in-depth literature review, stakeholder consultations as key informant interviews, and participatory mapping. Haldwani has experienced severe water scarcity due to depletion of groundwater, decline in the discharge rate of river Gaula, and drying of springs in and around the city. Various agencies manage the existing water resources in isolation and mismanagement of water is one of the prominent problems in the city. The paper delves into the nuances of various strategic interventions, and the respective institutional capability to undertake the same. While most of the strategies prevalent at international level are yet to be adopted in context of Himalayan cities, a key finding is that rain water harvesting system can be easily taken up as a nature based solution by each of the institutions since it also falls in their scope of work as well as to meet the city’s present and future water challenges.

Integrated Urban Water Management

Integrated Urban Water Management (IUWM) in land developments is becoming increasingly necessary in order to more efficiently utilise and manage water resources. Techniques including the control of stormwater runoff, increasing infiltration and providing opportunities for retention, treatment and reuse of both stormwater and wastewater, are well suited to being designed into the development rather than considered post-construction or not at all. There can be extensive capital investment by developers to implement IUWM which is often not returned in the land sales. This produces a disincentive for the developer unless the contribution is recognised and rewarded either financially or with appropriate marketing advantage. A system to rate land developments based upon IUWM has been developed that would quantifiably assess how effectively water resources would be utilised in a proposed land development. This assessment would provide a point of comparison between developments allowing property purchasers, developers, utilities and legislators to quickly compare how well the development performs in terms of IUWM, providing a mechanism for financial reward or recognition. This paper discusses the development of a model to quantifiably assess land developments for water efficient use and introduces a rating system with which land developments can be compared in terms of IUWM.
