policy transfer among regional level organizations insights from source Water Protection in ontario
Environmental Management, 2016Co-Authors: R C De Loe, Dan Murray, Sarah Michaels, Ryan PlummerAbstract:Organizations at the local and regional scales often face the challenge of developing policy mechanisms rapidly and concurrently, whether in response to expanding mandates, newly identified threats, or changes in the political environment. In the Canadian Province of Ontario, rapid, concurrent policy development was considered desirable by 19 regional organizations tasked with developing policies for Protection of drinking Water sources under very tight and highly prescribed mandates. An explicit policy transfer approach was used by these organizations. Policy transfer refers to using knowledge of policies, programs, and institutions in one context in the development of policies, programs, and institutions in another. This paper assesses three online mechanisms developed to facilitate policy transfer for source Water Protection in Ontario. Insights are based on a survey of policy planners from the 19 regional organizations who used the three policy transfer tools, supplemented by an analysis of three policies created and transferred among the 19 regional source Water Protection organizations. Policy planners in the study indicated they had used policy transfer to develop source Protection policies for their regions—a finding confirmed by analysis of the text of policies. While the online policy transfer tools clearly facilitated systematic policy transfer, participants still preferred informal, direct exchanges with their peers in other regions over the use of the internet-based policy transfer mechanisms created on their behalf.

source Water Protection in the annapolis valley nova scotia lessons for building local capacity
Land Use Policy, 2007Co-Authors: D K Timmer, R C De Loe, R D KreutzwiserAbstract:Abstract Protecting source Water using Watershed management strategies can help communities reduce the threat of drinking Water contamination. However, small communities face financial, human resource, institutional, social, and technical challenges that test their ability to protect drinking Water supplies. This research uses an in-depth case study analysis to evaluate the capacity of six small communities in Nova Scotia's Annapolis Valley to protect their drinking Water supplies. Communities in the Annapolis Valley have human resources and social networks that are capable of supporting source Water Protection activities. However, they face considerable institutional, financial, and technical constraints. The research reinforces the importance of provincial and local leadership, education of citizens, and building networks among actors to help communities overcome constraints on their capacity to protect drinking Water sources.

an institutional perspective on local capacity for source Water Protection
Geoforum, 2006Co-Authors: Janet L Ivey, R C De Loe, R D Kreutzwiser, Cecilia FerreyraAbstract:Abstract Provision of safe drinking Water is one of the global challenges of the 21st century. Effective Water treatment is a key aspect of drinking Water safety. However, just as important is ensuring that sources of drinking Water such as rivers and aquifers are protected from contamination. In that context, source Water Protection is recognized as the first barrier in a multi-barrier approach to drinking Water safety. Source Water Protection occurs at the local scale, and involves numerous local actors with varying capabilities. Consequently, institutional arrangements (IAs) for land use planning and Water management are key determinants shaping local capacity for source Water Protection. The purpose of this research was to evaluate the extent to which existing IAs enhance or constrain the capacity of local governments to protect source Waters. An evaluation framework, developed around four core elements drawing from functional and relational perspectives on capacity and capacity building, was applied to the Oldman River basin, Alberta. Results showed that local capacity for source Water Protection is constrained by existing IAs that do not encourage the generation of a locally relevant technical knowledge base and which assign legal authority for regulating intensive livestock operations to the provincial government. Formal mechanisms for integrating land use planning and Water management, which could help overcome these functional constraints and provide opportunities for broad public involvement, have yet to be developed in Alberta. Meaningful participation can provide local governments with an ability to encourage source Protection on private lands and enhance their leverage when confronting public land and livestock production issues. However, if local capacity is to be facilitated through IAs that encourage interaction among local governments, stakeholders and residents, then capacity building initiatives should also take into consideration how existing IAs help to maintain and to reproduce local power differentials.

analysis of long term Water quality changes in the kis balaton Water Protection system with time series cluster analysis and wilks lambda distribution
Ecological Engineering, 2011Co-Authors: Istvan Gabor Hatvani, Jozsef Kovacs, Ilona Kovacs, Pal Jakusch, Janos KorponaiAbstract:Abstract Lake Balaton is the largest shallow freshWater lake in Central Europe. Its Water quality is mainly affected by the supplying rivers and other Water sources. The primary source is the Zala River. Its Water used to be filtered by the Kis-Balaton Wetland (KBW) before entering Lake Balaton. During the nineteenth century, as a result of artificial Water level modifications, the KBW disappeared and the Zala River's Waters became partially unfiltered. It is for this reason that the Kis-Balaton Water Protection System (KBWPS) had to be constructed as a mitigation wetland. The aim of the study is to examine the available physical, chemical and biological parameters to get a more comprehensive picture of the processes evolving in the functioning of the KBWPS, and to make suggestions concerning the management and preservation of the system's wetland habitat. The central concept of the present study was to group the sampling points of the KBWPS and to determine which parameters had the greatest effect on the groups, and where. Multivariate data analysis was applied to the data concerning 25 chemical, biological and physical parameters for the time period 1984–2008 from 13 monitoring stations. The sampling locations were clustered then grouped. The groups were formed annually. The change of alignment of similar sampling points shows how the border between the determining groups (covering the eutrophic pond and wetland habitats) changed over the years. This change followed the transition from macrophyte vegetation to an open Water area which took place as a result of the Water level being kept artificially constant, and which did not therefore follow the weather conditions (rain, drought, etc.). Using Wilks’ λ distribution it was possible to determine that the parameters responsible for eutrophication were primarily responsible for forming the groups of the sampling points. The next most important factors determining the groups were the variables in close relation with the parameters characteristic of eutrophication. The inorganic chemical components affected the conformation of the groups the least. Finally, by examining the phosphorous forms and chlorophyll-a we tried to show the milestones in the history of the mitigation wetland, the KBWPS. The result of this research was that it points out changes in the KBWPS over a long time period, which had not been done previously. This research could hopefully help scientists to gain a broader perspective on processes evolving in the KBWPS. When it comes to finishing the second phase of the reservoir system, more knowledge will be available on what can be expected regarding the quality of the Water entering Lake Balaton, and the conservation of the nature preserve wetland area.

morlet wavelet and autocorrelation analysis of long term data series of the kis balaton Water Protection system kbwps
Ecological Engineering, 2010Co-Authors: Jozsef Kovacs, Istvan Gabor Hatvani, Janos Korponai, Ilona Szekely KovacsAbstract:Abstract Lake Balaton is the largest shallow freshWater lake in Central Europe. Its Water quality is mainly affected by the supplying rivers and other Water sources. The primary source is the Zala River. The Water of this river used to be filtered by the Kis-Balaton wetland (KBW) before entering Lake Balaton at Keszthely Bay. In the course of the nineteenth century, Water level modifications at KBW shrank and it lost its full capacity to function as a filter for the Zala's Waters, so the nutrient load of Lake Balaton greatly increased, and its Water quality started to deteriorate. This is the reason an artificial extended wetland called the Kis-Balaton Water Protection system (KBWPS) had to be constructed–to retain the inorganic nutrients at the mouth of the Zala River and stop the further degradation of Balaton's Water quality. In this study, Morlet wavelet spectrum (periodicity) analysis and autocorrelation (memory) analysis were used with weekly chemical, biological and physical data for the KBWPS for the period 1993–2007. We compared the periodicity and the memory of the parameters in the two different habitats of the KBWPS and the Zala River. We also analyzed the tracking capability of the periodical seasons of the two phases (the complete Phase I, and the incomplete Phase II) and the river. The results showed that the incomplete Phase II is unable to conserve the periodicity and sustain long memory because of the shading provided by the macrophyte cover and the extra inflows. In conclusion, we were able to point out the dependence of the system's processes on temperature and climate conditions with methods that have not yet been used for this kind of purpose.
