Domestic wastewater is one of the most interested environmental issues in Vietnam, especially in big cities and suburban residential areas. Most of the wastewater was not treated in the right way before discharging to environment. In this research, the author used water hyacinth as a main aquatic plant in aquatic pond model to treat wastewater. The experiment was operated continuously in 1 year with hydraulic retention time (HRT) is 11 and 18 days. Hydraulic loading rate (HRL) is 300 and 500 m3/ha/day, respectively. Treatment efficiency of the model for TSS is 90% (remaining 6 -12mg/l); COD, BOD5 is 63 - 81% (remaining 10 - 48mg/l); TP is 48 – 50% (remaining 3.5 - 9.8mg/l); TKN is 63 - 75% (remaining 8 - 17mg/l). Polluted parameters in effluent were lower than A and B levels of Vietnam standard QCVN 14: 2008/BTNMT and QCVN 40: 2011/BTNMT. The doubling time of water hyacinth in summer is 18days, and in autumn and winter is 28.5 days. Experiment results showed that we can use water hyacinth in aquatic pond to treat domestic wastewater with medium scale. We can apply this natural treatment method for residential areas by utilizing existing natural ponds and abandoned agricultural land with capacity up to 500m3/ha day. However, to get better efficiency we should combine with other aquatic plant species to treat wastewater and improve environmental landscape. Nước thải – xử lý nước thải sinh hoạt hiện đang là một trong những vấn đề môi trường được quan tâm tại Việt Nam nhất là tại các thành phố lớn và các khu dân cư. Hầu hết lượng nước thải chưa được xử lý đúng cách trước khi thải ra môi trường. Trong nghiên cứu này, tác giả sử dụng mô hình hồ thủy sinh và sử dụng cây Bèo lục bình để xử lý nước thải sinh hoạt của một khu dân thuộc huyện Từ Liêm, tại khu vực này nước thải bị thải trực tiếp vào sông Nhuệ. Thực nghiệm đã được tiến hành trong khoảng thời gian một năm, trải qua các mùa của khu vực miền Bắc với hai chế độ vận hành HRT là 18 và 11 ngày, tương ứng với tải trọng thủy lực HRL là 300 và 500 m3/ha/ngày. Kết quả cho thấy mô hình thủy sinh sử dụng cây bèo lục bình cho kết quả tốt, hiệu suất xử lý với các chất ô nhiễm đạt được như sau: chất rắn lơ lửng đạt 90%, COD, BOD5 đạt 63 - 81%, Phốt pho tổng giảm tới 48 - 50%, Nitơ tổng giảm tới 63 - 75%. Hàm lượng các chất ô nhiễm trong nước thải đầu ra của mô hình đều thấp hơn ngưỡng A và B của các tiêu chuẩn QCVN 14: 2008/BTNMT và QCVN 40: 2011/BTNMT. Bên cạnh đó tác giả cũng đã xác định định được tốc độ sinh trưởng của cây bèo tại khu vực miền Bắc là 18 ngày vào mùa hè và 28.5 ngày vào mùa thu đông. Kết quả nghiên cứu cho thấy có thể sử dụng bèo lục bình để xử lý nước thải sinh hoạt, với qui mô vừa và nhỏ và nên áp dụng cho các khu vực ven đô, nông thôn nơi có diện tích đất rộng hoặc tại các hồ sinh thái của các khu đô thị. Tuy nhiên, để hiệu quả tốt hơn ta cần kết hợp với nhiều loại thực vật thủy sinh khác để ngoài tác dụng xử lý nước thải mà còn tạo cảnh quan môi trường xung quanh.

Land consolidation works carried out in Poland are mainly aimed at the improvement of spatial structure of plots in agricultural holdings. However, modern trends indicate the necessity of compliance with sustainable rural development policy. This implicates the inevitability of inclusion of the environmental, landscape, technical and organizational aspects in the land consolidation projects in Poland. One such operation is the introduction of trees and shrubs. The paper aims to investigate the scope of land consolidation design solutions concerning the introduction of trees and shrubs. The study was based on selected land consolidation projects from different regions of Poland. The paper also proposes the concept of implementation of the design solutions related to the introduction of trees and shrubs in the land consolidation projects.

People suffering from Alzheimer's may feel anxious or unsettled as a result of these symptoms – in particular the decrease in their cognitive abilities and in their ability to take into account new information or external stimuli – as well from the effects of their medications. Because of their sensitivity, such individuals find it difficult to keep up a positive attitude and remain emotionally stable for long: they experience mood swings, and are unable to keep their negative emotions in check. For this reason, the best practice in treatment is to help them maintain a positive view of their lives and balance their emotions, both personally, in terms of keeping their sense of self, and in social environments, where they have to recognize and interact with others. In this way, good environmental landscape design will have an important role to play in improving their quality of life.

In this chapter, the author provides a unique set of insights concerning the policy of urban dynamics that is part of a complex process. The focus is on how disasters and development are understood and experienced through the lens of decolonial thinking based on a discussion of the displaced issue in a complex global socio-economic context of the city. Because the third world is associated with development needs to be reformulated in terms of dialogues from different enunciation loci, it becomes pertinent to consider the decolonial epistemic perspective in a space that constantly faces disasters that jeopardize its development in the framework of the effects on the environmental landscape and local development initiatives of Hurricane Dorian. Based on an informative discussion of an institutional level analysis, the author concludes with important insights about the case of Haitians in the Bahamas to demonstrate some interesting implications for (mis)management through NGOs.

A five year study has been made to establish the spread of the rice water weevil <em>Lissorhoptrus oryzophilus</em> (Coleoptera: Erirhinidae) in Northern Italy. Data obtained with GPS from 2005 throughout 2009 were first georeferenced with SW ArcGis&reg; 9.2, then overlapped and compared to the map of the European environmental landscape based on the interpretation of satellite images (CORINE Land Cover map) and to the hydrographic chart CT10 (Technical Regional map 10000). The analysis of the radial rate of spread per year indicates a deceleration in the expansion from 10.864 &plusmn; 6.801 km/year in 2005 to 5.318 &plusmn; 1.401 km/year in 2009. In five years the weevil has expanded its distribution in nearly all rice paddies in Lombardy and Piedmont, over an area of about 200,000 ha, which correspond to 86% of the total Italian rice area. Its expansion is thought to follow a type of stratified dispersal, due both to insect adult active dispersal and to accidental movements caused by human transportation.
