“…Resilience through water recycling in peri-urban agriculture reflects a connectivity with landscape processes and risk management needs [7]. Peri-urban agriculture in a case like this thus provides a pivotal link between the pattern of catchment or watershed management through the urban water cycle, and the proactive re-connectivity back through the peri-urban landscape.…”

“…A key spatial opportunity for capital accumulation was that of water harvesting, and water recycling as a strategy for re-organisation. Water recycling, risk management and agricultural use has been described by Attwater et al [7] as a key integrative strategy for connectivity in the peri-urban landscape. The following section describes the general peri-urban water cycle in which the case study of water reuse at the Western Sydney University Hawkesbury campus operates.…”

“…A key conclusion was the need for broad ranging risk management encompassing resilience for urban agriculture, optimising the multi-functionality of urban and peri-urban agriculture, and an understanding of environmental services and non-agricultural demands for land. In a recent article, Attwater et al [7] described how risk management of agricultural recycled water can support an integrative process for addressing broader risk management needs, assisting in the connectivity of our peri-urban landscapes, providing for multi-functionality and ecosystem services. This paper builds upon knowledge of the local peri-urban water cycle in Western Sydney, to identify attributes which contribute to resilience.…”

Pressures on urban, peri-urban and rural water and agricultural systems are increasingly complex with multiple interacting stresses and impacts. As a way of addressing these issues there has been increasing consideration as to how to build and manage resilience in these complex social-ecological systems. This paper presents a case study of the role of water recycling for agricultural use within the context of the peri-urban water cycle in Western Sydney, Australia. Building upon a description of the water cycle associated with water reclaimed from urban wastewater and stormwater harvesting; aspects which enhance resilience are identified and discussed. These include water resource security, avoidance of wastewater discharges to receiving waters, enhanced processes of landscape ecology, provision of ecosystem services, environmental risk management, local agricultural products and services, social values, livelihood opportunity, and the industrial ecology of recycled organics.

“…Globally, climatologists agree that sea water level is on a trajectory of crescent (see Figure1) and its tempo of crescendo is though a sign of grievousness [1,2] is still synchronously adumbrating nature's conquest over and superiority to man's known and possessed inventory of tactics and strategies to tackle the contrary phenomenon 'water depletion'(see Figure 2). It is quite evident from Figure 2 how the garve the situation has become [3,4].…”

A comprehensive analysis of water resources and global challenges are procedurally investigated. The climate influence on this vital resource is emphasized. It is seen that factual data lead to very grave situation for the human kind. Combining all influential parameters into account, there appears to be an impending danger for future sustainability. An attempt is made to bring all these into notice with plausible measures.

“…For each experimental run, dosing was maintained for three hours based on the dosing regime established elsewhere for effective cation capture [25,32], which complied with recorded median rainfall duration for the years 2010 to 2013 [33]. It must be noted that the dosing cycle was based principally on hydraulic and not climatological considerations given the endemically high rainfall variability on the Eastern seaboard relating to the El Nino Southern Oscillation, reducing the reliability of rainfall prediction since the year 2000 [34].…”

Abstract:The City of Sydney is constructing more than 21,000 square metres of street biofilter units (raingardens) in terms of their Decentralised Water Master Plan (DWMP), for improving the quality of stormwater runoff to Port Jackson, the Cooks River, and the historical Botany Bay. Recharge of the Botany Sand Beds aquifer, currently undergoing remediation by extraction of industrial chlorinated hydrocarbon pollutants, is also envisaged. To anticipate the pollution removal efficiency of field biofilter designs, laboratory soil-column simulations were developed by Western Sydney University partnered with the City. Synthetic stormwater containing stoichiometric amounts of high-solubility pollutant salts in deionised water was passed through 104 mm columns that were layered to simulate monophasic and biphasic field designs. Both designs met the City's improvement targets for total nitrogen (TN) and total phosphorus (TP), with >65% median removal efficiency. Prolonged release of total suspended solids (SS) on startup emphasised the need for specifications and testing of proprietary fills. Median removal efficiency for selected heavy metal ecotoxicants was >75%. The researchers suggested that Zinc be added to the targets as proxy for metals, polycyclic aromatic hydrocarbons (PAH) and oils/greases co-generated during road use. Simulation results suggested that field units will play an important role in meeting regional stormwater improvement targets.
