“…Another growing trend in urban forest enhancement is incentive-based programs that offer financial or non-financial motivation for residents, businesses, and organizations to take part in urban forest stewardship activities (e.g., free-tree programs) with the long-term goal of changing citizen behaviours and fostering stewardship [119,120]. Lastly, many cities are adopting comprehensive and strategic urban forest management plans [28].…”

Trees in Canadian Cities: Indispensable Life Form for Urban Sustainability

Abstract:We argue that a healthy urban forest contributes immensely to the sustainability of cities. The argument is based on a comprehensive array of values elicited from Canadians in several cities. To begin, we define the urban forest as inclusive of all the trees in the city and thus representing the predominant contributor to a city's green infrastructure. Then we enumerate and explain the broad diversity of ways in which urban people value trees in the city. We, thus, show the myriad pathways by which trees contribute positively to any city's social, economic, and ecological sustainability. Following a short summary of the ways in which trees may detract from people's quality of life, we present promising management directions for urban-forest improvement, as we understand the situation in Canada. We conclude that all cities can enhance their sustainability by improving the urban forest.

“…Direct costs include all of the costs associated with planting and maintaining trees, including the purchase of the tree, cost of planting the tree, and subsequent pruning, watering, leaf removal, program administration, and eventual tree and stump removal/disposal [8][9][10]. Typical infrastructure interference costs are the costs of pavement and sewer repair and power outages caused by falling limbs or trees [10,13,14]. Some important negative externalities, or ecosystem disservices, associated with trees include emissions of biogenic VOCs, release of carbon dioxide (CO 2 ) during maintenance activities and from leaf and wood decomposition, and allergies caused by pollen release [10,12].…”

Trees provide numerous benefits for urban residents, including reduced energy usage, improved air quality, stormwater management, carbon sequestration, and increased property values. Quantifying these benefits can help justify the costs of planting trees. In this paper, we use i-Tree Streets to quantify the benefits of street trees planted by nonprofits in three U.S. cities (Detroit, Michigan; Indianapolis, Indiana, and Philadelphia, Pennsylvania) from 2009 to 2011. We also use both measured and modeled survival and growth rates to "grow" the tree populations 5 and 10 years into the future to project the future benefits of the trees under different survival and growth scenarios. The 4059 re-inventoried trees (2864 of which are living) currently provide almost $40,000 (USD) in estimated annual benefits ($9-$20/tree depending on the city), the majority (75%) of which are increased property values. The trees can be expected to provide increasing annual benefits during the 10 years after planting if the annual survival rate is higher than the 93% annual survival measured during the establishment period. However, our projections show that with continued 93% or lower annual survival, the increase in annual benefits from tree growth will not be able to make up for the loss of benefits as trees die. This means that estimated total annual benefits from a cohort of planted trees will decrease between the 5-year projection and the 10-year projection. The results of this study indicate that without early intervention to ensure survival of planted street trees, tree mortality may be significantly undercutting the ability of tree-planting programs to provide benefits to neighborhood residents.

“…The most common causes are build up of fats, oils and greases (FOGs), debris, or other solid deposition, tree root intrusion and sewer line collapse (Arthur et al 2008;Geyer & Lentz 1966;Randrup et al 2001). Build up of FOGs and solids deposition are likely to be influenced by the wastewater characteristics that enter the sewer network whereas sewer line collapse results from hydraulic and physical factors such as large flows, pipe age as well as pipe condition (Arthur et al 2008).…”

Prolonged drought which is occurred everywhere around the world has caused water shortages, leading many countries to consider more sustainable practices which are called Source Management Practices (SMPs) to ensure water availability for the future. SMPs include the practices of water use reduction, potable water substitution and wastewater volume reduction such as water demand management, rainwater harvesting, greywater recycling and sewer mining. Besides the well known advantages from SMPs, however they also contribute to the alteration of wastewater characteristics which finally affecting the process in downstream infrastructure such as sewerage networks. Several studies have shown that the implementation of SMPs decreases the wastewater flow, whilst increasing its strength. High strength wastewater can cause sewer problems such as sewer blockage, odour and corrosion. Yet, not all SMPs and their impact on existing sewer networks have been investigated. Therefore, this study reviews some examples of four common SMPs, the wastewater characteristics and the physical and biochemical transformation processes in sewer and the problems that might caused by them and at last, the potential impacts of those SMPs on wastewater characteristics and sewer networks are discussed. This paper provides sewer system managers with an overview of potential impacts on the sewer network due to the implementation of some SMPs. Potential research opportunities for the impact of SMPs on existing sewers are also identified.
