Factors Influencing Household Outdoor Residential Water Use Decisions in Suburban Boston (USA)Argo, Emily E 04 November 2016 (has links)
Water withdrawals for human use can reduce water in lakes and streams, with significant consequences for aquatic biota. Urbanization, particularly large lawn areas associated with low-density residential development, increases demand on freshwater resources. Outdoor water use accounts for the largest proportion of residential water use during the summer months, which corresponds to the lowest water levels in freshwater ecosystems. Prior studies have sought to understand property features associated with the highest water use; however, these studies do not consider other types of water use nor do they capture the decisions by residents that result in outdoor water use. Understanding these decisions is critical for developing policies and education tools that reduce outdoor water use by changing people’s water use behavior. Focusing on the Ipswich River Watershed, which has been impacted by extreme low flows due to water withdrawals, a mixed-methods approach was used to understand residents’ outdoor water use and the factors influencing the amount and timing of water use. To quantify water use meters were placed on outdoor spigots at residences, participants were provided with a written survey before and after water metering, and in-person interviews were conducted. Irrigation systems used the most water; however, garden watering occurred as frequently as lawn irrigation and many participants indicated that their garden was a primary factor in water use decisions. Participants’ water use decisions fell into categories from habitual (i.e., watering at the same time of day) to purely cognitive (i.e., watering based on weather and plant needs). While many participants felt that water conservation was necessary, their willingness to implement landscape-level conservation practices, such as rain barrels, did not differ from participants who believed water conservation was unnecessary. Interestingly, many residents reduced their outdoor water use behavior and increased their concern for other environmental issues in response to study participation. To have the greatest impact on overall water use, efforts should focus on residents running irrigation systems on a schedule. Outreach should emphasize individualized approaches to water conservation, regardless of water source (public or private), and include information and conservation options specific to the water needs of the individual property.

ARE PEOPLE RESPONSIVE TO WATER RATIONING POLICIES?2015 September 1900 (has links)
It is difficult for policymakers to predict the behavior of people in response to a water rationing policy. The public may not necessarily behave as expected or in accordance with market rules or policy mandates. In this research, I will ask whether people were responsive to a summer 2011 City of Saskatoon legal restrictions to reduce their outdoor water consumption due to reduced capacity at the water treatment plant resulting from excessive solids in the river water. I will try to explore the policy response - which can be expressed as a reduction of outdoor water consumption in 2011 in response to the water mandate - while holding constant other factors, including environmental variables (temperature and rainfall), socio-economic factors (income and education level), lot size, and an annual downward trend in water consumption that appeared in many North American cities during the past two decades.
Monthly water consumption data for the period from 2004 to 2012 for the City of Saskatoon were analyzed to detect if there is a policy response from the water mandate during June and July 2011. Regression analysis with water consumption as the dependent variable and lot size, temperature, rainfall, education index, income, consumption trend, and policy as independent variables was conducted to test whether there is a policy response in the Saskatoon water records, holding other factors relevant to water consumption constant.
Results showed there was a statistically significant reduction in Saskatoon water consumption during June and July 2011 as a result of the water rationing mandate, with considerable variations through different neighborhoods. In addition, there is a positive relationship between water consumption and lot size and a reduction in water consumption over the research period from 2004 to 2012. The policy response varied widely across neighborhoods, and there was relationship between policy and annual income per capita, and household size; households with more income per capita are less responsive to the policy while bigger household sizes showed more policy responsiveness.
Key words: City of Saskatoon, water rationing, water policy, water mandate, outdoor water use.
