Abstract With the faster urbanization and the higher living environment requirements of people, the urban green area is getting increasingly attention. But green irrigation consumes huge tap water, causes the waste of high-quality water resources. The reclaimed water meets the standard of green irrigation and the source is sufficient, it is a good alternative water source for urban greening. The eco-economic benefit of using reclaimed water as greening water was evaluated in this paper. The composition of benefit was analyzed and the difference in benefit brought by using reclaimed water greening instead of tap water was quantified based on emergy theory. Taking Zhengzhou in 2018 for example, the results showed that the eco-economic benefit of reclaimed water greening was remarkable. The total eco-economic benefit was $4.05 billion, which was three times of that of tap water. Among the benefits, economic benefit accounted for the largest proportion, reaching 69.22%. After deducting the cost, the net eco-economic benefit of reclaimed water greening was $2.00 billion, while tap water was negative. Therefore, using reclaimed water to irrigate urban green area can save a lot of high-quality water and bring a lot of economic, social and ecological environmental benefits. The quantitative results of this paper can provide reference for the promotion of reclaimed water greening and the allocation decision of reclaimed water in water shortage areas. And it is helpful to improve the utilization efficiency of water resources and alleviate the shortage of urban water resources.

Abstract Improper utilization of water resources has the potential to result in reduced availability of high-quality water and adverse effects on societal development. In fact, what appears to be a serious gap in comprehensive water resources studies is the lack of a coherent approach that can link different social, economic and environmental parts within the framework of the integrated water management paradigm to extract strategies and operational plans. Comprehensive water resources management (CWRM) is a process that intends to develop and manage water, land and other resources in a way that maximizes the social and economic well-being of human societies, without compromising the integrity and sustainability of vital ecosystems and future benefits. This chapter discusses the definitions of integrated and comprehensive water resources management describing the steps of using integrated management in practical examples.

Plant blindness is a recurrent issue in many urban green spaces. As an element of biodiversity perception, it is socially and individually determined. This paper brings up evidences of plant blindness through a quali-quantitative analysis of 49 interviews on an urban green area of the São Paulo state whose several trees have been recently plaqued. Respondents were not able to correctly identify plant elements and undervalued richness of different types of plants. Despite pointing out the necessity of green spaces in improving quality of life, respondents underestimated the importance of maintaining not only a green space, but a biodiverse one. We discuss the perception of a “good” green space is less associated with species richness, and more with passers-by expectations on a green space and with an innate plant blindness. We suppose informative plaques may play a role in reduce plant blindness, since plaques individualize plants that were once seen as components of a monotonous green landscape.

The Urban Green Areas System (UGAS) performs relevant functions for the quality of life by making cities healthier, which has become even more necessary in the current period of pandemic. However, even with these benefits, the practice of urban management indicates difficulties not only in the implementation, but also in the maintenance of the UGAS. One of the aspects that may explain the challenge of implementing and maintaining green areas in cities is the absence of regulatory instruments and financial incentives that support this system. In this line, in order to contribute to this discussion, one of the instruments that proved to be effective in environmental management will be studied, in this case for the creation and implementation of Conservation Units: the “ICMS Ecológico”. This article will study the characteristics of the UGAS associated with ecological and urban functions; the logic of adopting the “ICMS Ecológico” and will seek to define criteria that can be used for the implementation of a UGAS that prioritizes ecosystem thinking associated with the function of urban health. We started with the discussion about the mechanisms for adopting the “ICMS Ecológico” and followed the analysis of the standards established in the states for its application. As a result, it was found that there are similarities that can be applied to an implementation in the urban green area systems, which allowed the recommendation of criteria that can be used as a reference for the application of the “ICMS Ecológico” to support the UGAS and the promotion of healthier cities.

The studies were conducted in Lublin in the years 1999-2001 in two sites (street and park ones) on the trees <i>Crataegus</i> x <i>inedia</i> Bechst. The purpose was to determine the domination and frequency of particular aphid species, their effect on the decorative character of plants as well as the occurrence of the aphidophagous in aphid colonies. It was found out that A. <i>pomi</i> was the dominating species in both sites. The decorative character of the studied trees was lowered by aphids A. <i>pomi</i> and aphids from the genus <i>Dysaphis</i>. Aphids from the genus <i>Dysaphis</i> also caused changes in the chemical composition of the injured plant parts. The presence of predatory arthropods was observed in aphid colonies occurring on hawthorn. The most numerous of these were the larvae of <i>Syrphidae</i> and <i>Coccinellidae</i>. The culture of parasitized aphids gave numerous flights of parasitoids and hyperparasitoids. Greater number of both predators and parasitoids of I and II grades were observed in the street site as compared to the park site.

In order to implement market principles and mechanisms in the field of management and financing of agriculture and water resources in Uzbekistan, organizational forms, regulations, methods and tools of management in this area are being radically improved. Agro-industrial clusters are a potential source of financing for water management organizations, they have a great potential for providing high-quality water management services and introducing paid water use based on market mechanisms.
