Exploring Attitudes Towards Water Collaboration for Source Water Protection Between First Nations and Ontario Municipalities

My research will examine how collaborative source water protection planning involving First Nations, municipalities, and conservation authorities can act as an avenue for enhancing water security on-reserves in southern Ontario. There is plenty of academic literature that examines the extent of water quality issues on First Nations reserves in Canada, and on the factors that contribute to the problem. However, what is lacking are those focused on collaborative efforts between First Nations, municipalities, and conservation authorities. This gap has been acknowledged by other academics in the field. For example, Nelles and Alcantara (2011) claim scholars have ignored the variety of inter-governmental agreements between Indigenous communities and municipal governments in Canada. “We know very little about collaborative agreements, how or why they have emerged or failed to emerge, and whether or not they would be successful” (Nelles and Alcantara, 2011). Some questions have yet to been answered, such as, what collaborative models currently exist that would enable source water protection? What kind of relationships exist between First Nations and their neighbouring municipalities and conservation authorities? How can these relationships work to positively impact source water protection in the region? The goal of this research is to assess the attitudes, opinions, and experiences of First Nations, Municipalities, and Conservation Authorities in a shared watershed to determine how they might be able to work towards collaborative source water protection planning. A case study approach will be used with COTTFN, the City of London, and Upper and Lower Thames Conservation Authorities. This document will act as a guide to collaborative efforts and relationship building can enhance source water protection.

Urban groundwater use in Tropical Africa – a key factor in enhancing water security?

Abstract A regional scoping study has reviewed the limited data on groundwater use for 10 cities in Tropical Africa. In those cities where the water utility has been able to develop groundwater rationally, the public water-supply usually offers a better service at lower cost by enabling phased investment and avoiding advanced treatment, and offers greater water-source security in drought and from pollution. Urban dwellers obtain water from multiple sources, according to availability and affordability. Among the more affluent, private water-supply boreholes are increasingly used to improve security and reduce cost but in the absence of international charity finance groundwater access is beyond the financial reach of the urban poor, except where the water table is shallow allowing the use of low-cost dugwells. The way forward must be to integrate more effectively utility and private investments, and piped and non-piped solutions, for urban water-supply provision, and for water utilities to establish low-income (‘pro-poor’) policy and technical units to pursue ways of supporting alternative water-supply provision, including advisory services and regulatory functions (where appropriate) for private borehole and dugwell use. To facilitate this, water utilities will need to partner with resource regulators and knowledge centres, which may require modifications to their mandate.

Evaluating the variability in surface water reservoir planning characteristics during climate change impacts assessment

Summary This study employed a Monte-Carlo simulation approach to characterise the uncertainties in climate change induced variations in storage requirements and performance (reliability (time- and volume-based), resilience, vulnerability and sustainability) of surface water reservoirs. Using a calibrated rainfall–runoff (R–R) model, the baseline runoff scenario was first simulated. The R–R inputs (rainfall and temperature) were then perturbed using plausible delta-changes to produce simulated climate change runoff scenarios. Stochastic models of the runoff were developed and used to generate ensembles of both the current and climate-change-perturbed future runoff scenarios. The resulting runoff ensembles were used to force simulation models of the behaviour of the reservoir to produce ‘populations’ of required reservoir storage capacity to meet demands, and the performance. Comparing these parameters between the current and the perturbed provided the population of climate change effects which was then analysed to determine the variability in the impacts. The methodology was applied to the Pong reservoir on the Beas River in northern India. The reservoir serves irrigation and hydropower needs and the hydrology of the catchment is highly influenced by Himalayan seasonal snow and glaciers, and Monsoon rainfall, both of which are predicted to change due to climate change. The results show that required reservoir capacity is highly variable with a coefficient of variation (CV) as high as 0.3 as the future climate becomes drier. Of the performance indices, the vulnerability recorded the highest variability (CV up to 0.5) while the volume-based reliability was the least variable. Such variabilities or uncertainties will, no doubt, complicate the development of climate change adaptation measures; however, knowledge of their sheer magnitudes as obtained in this study will help in the formulation of appropriate policy and technical interventions for sustaining and possibly enhancing water security for irrigation and other uses served by Pong reservoir.

Enhancing water security in a rapidly developing shale gas region

Study regionThis study is based in the rapidly developing shale gas region of Northeast British Columbia, Canada. Study focusWater security is central to decision-making within a water–energy nexus. In areas where energy resources, such as shale gas, are undergoing rapid development, water security and the associated risks to water quality and quantity are of paramount concern. However, in many regions there is a lack of understanding and data on the hydrologic system, particularly its vulnerability to hazards. The data and knowledge gap poses challenges for effective regulation of the shale gas activities and management of water resources. This paper describes initiatives that are addressing concerns surrounding water security in Northeast British Columbia. New hydrological insights for the regionInitiatives and tools enhancing water security in the region include strategic partnerships and stakeholder collaborations, policy and regulation development, and data collection and distribution efforts. The contributions and limitations of each of these are discussed. A vulnerability mapping framework is presented which addresses data gaps and provides a tool for decision-making surrounding risk to water quality from various hazards. An example vulnerability assessment was conducted for wastewater transport along pipeline and trucking corridors.

Quantifying the uncertainties of climate change effects on the storage-yield and performance characteristics of the Pong multi-purpose reservoir, India

Abstract. Climate change is predicted to affect water resources infrastructure due to its effect on rainfall, temperature and evapotranspiration. However, there are huge uncertainties on both the magnitude and direction of these effects. The Pong reservoir on the Beas River in northern India serves irrigation and hydropower needs. The hydrology of the catchment is highly influenced by Himalayan seasonal snow and glaciers, and Monsoon rainfall; the changing pattern of the latter and the predicted disappearance of the former will have profound effects on the performance of the reservoir. This study employed a Monte-Carlo simulation approach to characterise the uncertainties in the future storage requirements and performance of the reservoir. Using a calibrated rainfall-runoff (R-R) model, the baseline runoff scenario was first simulated. The R-R inputs (rainfall and temperature) were then perturbed using plausible delta-changes to produce simulated climate change runoff scenarios. Stochastic models of the runoff were developed and used to generate ensembles of both the current and climate-change perturbed future scenarios. The resulting runoff ensembles were used to simulate the behaviour of the reservoir and determine "populations" of reservoir storage capacity and performance characteristics. Comparing these parameters between the current and the perturbed provided the population of climate change effects which was then analysed to determine the uncertainties. The results show that contrary to the usual practice of using single records, there is wide variability in the assessed impacts. This variability or uncertainty will, no doubt, complicate the development of climate change adaptation measures; however, knowledge of its sheer magnitude as demonstrated in this study will help in the formulation of appropriate policy and technical interventions for sustaining and possibly enhancing water security for irrigation and other uses served by Pong reservoir.

The cost of noncooperation in international river basins

In recent years there has been a renewed interest for water supply enhancement strategies in order to deal with the exploding demand for water in some regions, particularly in Asia and Africa. Within such strategies, reservoirs, especially multipurpose ones, are expected to play a key role in enhancing water security. This renewed impetus for the traditional supply‐side approach to water management may indeed contribute to socioeconomic development and poverty reduction if the planning process considers the lessons learned from the past, which led to the recommendations by the World Commission on Dams and other relevant policy initiatives. More specifically, the issues dealing with benefit sharing within an efficient and equitable utilization of water resources are key elements toward the successful development of those river basins. Hence, there is a need for improved coordination and cooperation among water users, sectors, and riparian countries. However, few studies have explicitly tried to quantify, in monetary terms, the economic costs of noncooperation, which we believe to be important information for water managers and policy makers, especially at a time when major developments are planned. In this paper we propose a methodology to assess the economic costs of noncooperation when managing large‐scale water resources systems involving multiple reservoirs, and where the dominant uses are hydropower generation and irrigated agriculture. An analysis of the Zambezi River basin, one of the largest river basins in Africa that is likely to see major developments in the coming decades, is carried out. This valuation exercise reveals that the yearly average cost of noncooperation would reach 350 million US$/a, which is 10% of the annual benefits derived from the system.

Enhancing water security in Saskatchewan, Canada: an opportunity for a water soft path

This paper explores the methodological and organizational feasibility of conducting a water soft path study for Saskatchewan. Arguably, the methodology for soft path analysis is well developed and data availability for such a study in Saskatchewan is comparatively good. Given the many pressures on water resources in Saskatchewan, the timing is opportune for setting a different path for a water future in this prairie province that will enhance water security. A soft path for water may provide the means for such a future.
