AbstractFifty-four water samples were collected between July and December 2019 at nine monitoring stations and fifteen parameters were analysed to provide an updated diagnosis of the Piabanha River water quality. Further, forty years of monitoring were analysed, including government data and previous research projects. A georeferenced database was also built containing water management data. The Water Quality Index from the National Sanitation Foundation (WQINSF) was calculated using two datasets and showed an improvement in overall water quality, despite still presenting systematic violations to Brazilian standards. Principal components analysis (PCA) showed the most contributing parameters to water quality and enabled its association with the main pollution sources identified in the geodatabase. PCA showed that sewage discharge is still the main pollution source. The cluster analysis (CA) made possible to recommend the monitoring network optimization, thereby enabling the expansion of the monitoring to other rivers. Finally, the diagnosis provided by this research establishes the first step towards the Framing of water resources according to their intended uses, as established by the Brazilian National Water Resources Policy.

Qualitative Characteristics

The results of a comprehensive agroecological assessment of the main watercourses of the Zuya river basin are presented. Studies were conducted in 2017–2020 and included: conducting a visual survey, measuring water consumption, assessing the qualitative characteristics of runoff, including phytotesting and determining its suitability for irrigation purposes. It was determined that the main pollutants of the watercourses were sulphates, phosphates, heavy metals. The assessment of salt composition of water resources has shown that they are mostly suitable for irrigation without restriction. However, according to the results of phytotesting, an inhibitory effect was recorded, which indicates a possible decrease in the yield of crops sensitive to water-contained pollutants. The water balance calculations showed the presence of a shortage of water resources in the Zuya river basin. The environmental situation on the surveyed water bodies was identified as unfavorable. The set of priority environmental measures includes: the creation of a permanent monitoring network, the arrangement of settlements with water disposal systems, the inventory of small water storage facilities and the implementation of the required repair and operational work on them, and the optimization of the number of water users.

Negative Impacts

The environment, over the years, has been subjected to strong negative impacts caused by economic policies that have promoted an uncontrolled growth of urbanization in the cities and abusive exploration of the natural resources. In this context, developing socio-environmental indicators to subsidize the formulation of municipal public policies which consider, specifically, the environmental (in)salubrity of each neighborhood or locality of municipalities is imperative. The present paper presents the construction and application of an environmental health indicator for residential neighborhoods in two localities of Caruaru City, Pernambuco State. The data adopted in research were obtained from databases of City Hall institutions, from interviews with the population of the localities and water quality analyses. The results indicated that the neighborhoods analyzed presented characteristics of medium health; water supply, the disposal of solid waste, and socioeconomic aspects require attention and priority of public policies. In conclusion, the proposed indicator can be an instrument to assist in urban planning and environmental management of Brazilian municipalities, because it can guide the performance of public managers and the civil society to identify priority actions for improving the infrastructure of the most unhealthy neighborhoods.

Abstract Background: Despite the negative connotation of urban sprawl for bat populations, fragmented green spaces such as parks, cemeteries, and golf courses have the potential to provide necessary resources for bats. For example, water resources in these areas can include natural or semi-natural lakes, ponds, streams, and drainage ditches. Such water resources, however, are frequently ephemeral when subject to prolonged periods of high temperatures. We, therefore, hypothesize that bats will expand or shift their home ranges from these urban green spaces into the surrounding neighborhoods to access alternative resources, such as residential swimming pools. Methods: To explore whether bats expand their ranges from urban green spaces, we conducted a telemetry study in which we radio-tracked resident evening bats (Nycticeius humeralis) in a local park system during their summer activity period from 2017-2019 in Fort Worth, Texas, USA. From radio-tracking surveys, we measured home range size using a k-LoCoH method and the percentage of these home ranges that fell within the park system. We compared these variables using linear and non-linear regressions with temperature. Results: We successfully tracked a total of 30 bats over the 3-year period and found a positive correlation between home range size and temperature. Furthermore, we observed that home ranges increased 6 times in size when temperatures exceeded 30ºC. Conclusions: Our study indicates the importance of urban neighborhoods surrounding green spaces in providing alternative resources, such as water, for bats. If managed appropriately, these urban areas have the potential to act as urban oases for bat populations, which in turn can contribute to their conservation.

Urban Water Management

Water resources in many urban areas are under enormous stress due to large-scale urban expansion and population explosion. The decision-makers are often faced with the dilemma of either maintaining high economic growth or protecting water resources and the environment. Simple criteria of water supply and drainage do not reflect the requirement of integrated urban water management. The Urban-Water Harmony (UWH) model is based on the concept of harmony and offers a more integrated approach to urban water management. This model calculates four dimensions, namely urban development, urban water services, water–society coordination, and water environment coordination. And the Analytic Hierarchy Process has been used to determine the indices weights. We applied the UWH model to Beijing, China for an 11-year assessment. Our findings show that, despite the severe stress inherent in rapid development and water shortage, the urban water relationship of Beijing is generally evolving in a positive way. The social–economic factors such as the water recycling technologies contribute a lot to this change. The UWH evaluation can provide a reasonable analysis approach to combine various urban and water indices to produce an integrated and comparable evaluation index. This, in turn, enables more effective water management in decision-making processes.

<p>This research, conducted within the H2O-T2S project, is located in peri-urban areas of three cities in India: Pune, Hyderabad, Kolkata. Peri-urban areas are where the rural to urban transition is most visible. A key challenge for peri-urban areas is sustainable management of water resources. Peri-urban water resources in India are under threat from growing water demand and ineffective institutions. Interdisciplinary research of existing water-based livelihoods, household water use, and peri-urban institutions in these three regions shows that current urban transformations are unsustainable. Given the dynamic nature of peri-urban contexts, short and long-term vulnerabilities must be considered. An adaptation policy pathways approach can help peri-urban actors develop longer-term transformative plans. This study describes the design and execution of a participatory process to design context-specific pathways with peri-urban communities and governments in India.</p><p>This presentation outlines the key steps in our customized pathways approach for the peri-urban context. Due to the covid-19 pandemic, initial plans to implement these steps through a series of stakeholder workshops were replaced by remote pathways design using the Delphi method. We present a step-by-step methodology to engage peri-urban actors in the design of longer-term adaptive plans for water resources in the future. Results are presented for Hadia village (Kolkata), one of the three peri-urban case studies. It reveals the range of future normative scenarios developed for this village and a pathways schematic towards these scenarios.</p><p>Our results demonstrate the value of engaging local actors in the design of adaptive plans for peri-urban water resources. This study offers insights for ways to conduct transdisciplinary research even when face to face interactions are not feasible.</p>
