Abstract Fig (Ficus spp.) trees have been known as keystone species in the tropics and provide food sources for various species. The study aimed to reveal the diversity of fig trees in a tropical urban residential area of Sentul City, Bogor, West Java, as a part of a bigger study on the wildlife-fig relationship. A purposively selected sample (270 ha of housing, boulevard) and all Ficus were censused. Data on species diversity, height, diameter, and fruiting stage were taken. There were 389 Ficus trees, belonging to 10 species, namely F. benjamina, F. binnendykii, F. caulocarpa, F. elastica, F. kurzii, F. lyrata, F. maclellandii, F. macrocarpa, F. septica, and F. variegata, of which two species (F. lyrata and F. maclellandii) were non-native species. Ficus were planted as a border, roadsides, shading trees, or ornament. Based on the number of individuals, the most common species was F. benjamina (63.75%), followed by F. kurzii (14.4%) and F. lyrata (9.5%). As the F. benjamina can grow big, only about half (56.4%) were in full tree condition, while the rest were pruned (15.5%), trimmed (14.7%), or cut off (13.4%). This study showed that the diversity of fig trees in residential areas of Sentul City, Bogor is affected by the area’s management.

The suburban bird community of Wagga Wagga, N.S.W., was surveyed during December 1978-January 1979 and May 1979, at nine sites selected to cover all ages of residential areas from predevelopment to oldest suburbs and to demonstrate how the bird community will change with time in response to changing habitat. Non-residential sites were also sampled. Sites were censused by foot transect. House sparrows which were present in all sites, were the first species to colonize new residential areas and made up over 95% of the individual count of four sites Of native species, 40% were found in undeveloped sites only. The population density of undeveloped sites was only half that of developed sites, but the greatest species diversity was found in undeveloped sites and the lowest in the most altered sites. There was strong evidence for a steady linear increase in numbers of individuals, numbers of species, biomass and population density with increasing age of residential area, reaching a peak at about 30 years.

AbstractThe site of Sirkeli Höyük in the province of Adana in modern Turkey is one of the largest settlement mounds in Plain Cilicia. In 2012, a geophysical survey revealed that the ancient settlement was not confined to the höyük, but also encompassed an extensive lower town to the southeast of the main mound. To gain information on the dating and development of this part of the settlement, an excavation area (“Sector F”) was opened at a spot where the magnetometry survey suggested the presence of a city gate. Since then, archaeological work in this area has continuously produced new discoveries that help us understand how this residential area and its inhabitants developed throughout the periods of its occupation. Especially the Iron Age (Neo Cilician period) levels, which cover approximately the 11th–7th centuries B.C., provide important information on how this urban center of the Neo Hittite kingdom Hiyawa/Que changed over time and to which extent historical events impacted the people living in one of its residential areas. This contribution discusses the stratigraphic sequence, the pottery, and the archaeobotanical remains discovered in Sector F during the 2013–2019 campaigns, and concludes with a synthesis of the development in this area from a historical perspective.

The genus Cleome is widely distributed in drier areas of the tropics and subtropics. Cleome dendroides and C. rosea are Brazilian native species that occur mainly in Atlantic Forest and sandy coastal plains, respectively ecosystems negatively affected by human impacts. Cleome spinosa is frequently found in urban areas. Many Cleome species have been used in traditional medicine, as C. spinosa. In the present work, was investigated C. dendroides, C. rosea and C. spinosa germinative behavior under in vivo conditions, as well as was established suitable conditions to in vitro germination and seedling development. The in vivo germination was performed evaluating the influence of temperature, substrate and light. It was observed that only C. spinosa seeds presents physiological dormancy, which was overcome by using alternate temperatures. The substrate influenced significantly the germination of C. rosea and the seeds of C. dendroides showed the highest germination percentages in the different conditions evaluated. The post-seminal development stages under in vivo and in vitro conditions were defined. It was observed that the development was faster under in vitro than in vivo conditions. An effective methodology for in vitro germination, enabling the providing of material to experiment on plant tissue culture was established to C. dendroides and C. spinosa.

The natural ventilation of residential areas has placed more and more emphasis on residential area planning, according to the relationship between natural ventilation environments and the layout of architecture, we can reduce the energy consumption and the adverse effect of wind outdoors, improve the living environment and quality of life, making harmony between human and the nature. In this paper, we use Air-Pak to simulate the wind environment of residential areas. Through analyzing and simulating the air field which forms when the wind blows around the residential buildings by Air-Pak, we explain the advantage of the combination of computer simulation software and residential area planning. And we give some advice to the layout of the outdoor environment early in the residential planning area by the simulation of outdoor environments of buildings.

The existence of injustice and inequality in access to the development results of the city. Slum areas have become one of the problems that exist in urban life. This automatically occurs as a result of a normal process called urbanization and development. Where many residents end up occupying non-residential areas due to their limited access. Seeing from the perspective of the access theory, how people live in the area is a form of their right to be able to utilize natural resources. One of these uses is used as a place to live. This study used a qualitative descriptive method, by taking several samples as a source of interviews. The arrangement of the slum area is now moving to another dimension, which is no longer forced evictions, but how to organize and change the residential area to be habitable. There are several indicators used in seeing a residential area that is said to be unfit for habitation. Upgrading slum areas have been able to change areas that were previously unfit to be better and able to meet indicators of the feasibility of residential areas in general. This step is also how the community continues to strive to gain access to the area. Kampung Jodipan and Kampung Tridi have changed their appearance, and have improved the quality of their living environment, with tidier, cleaner, and more affordable access to public services. Apart from the results of this research, there are still some problems, one of which is the uncertainty of land rights, so that they will not know the future of the area they live in now. The guarantee of land ownership is important to fight for equal rights to state services, state recognition, and the right to live in the area.

This study was conducted to assess the building coverage and environmental quality of residential area in Nkpor Uno Idemili North L.G, Nigeria. The study employed a descriptive survey design to find out level of compliance of buildings to planning regulations. One hundred and eighty (180) were interviewed using a modified instrument (questionnaire). The data collected were coded into SPSS and analyzed with descriptive statistics. The results showed that 72(40%) reported inadequate setback as a major effect of over built buildings, 55(30.6%) reported inadequate free air space, 37(20.6%) said inadequate ventilation and lighting. Also, the nature of drainage system provided in residential areas; 76(42.2%) has no drainage system, 70(38.9%) has close drainage system. The building coverage of residential houses in the study area; 60(33.3%) has their building falls under 51-75% for over built, 48(26.7%) has their building falls under 76-100% for overbuilt. For the factors influencing the percentage of area built upon, 57(31.7%) has greed and no money to acquire a large plot of land, 47(26.0%) has no land space to built their desirable house. Then, non adherence to provision of adequate ventilation and lighting in the residential houses in the study area affects the dwellers’ health and such factors can promote communicable diseases. In conclusion, it was observed that the compliance rate was not encouraging because the planning regulations recorded very low compliance as include set–back from property boundaries; inadequate free air space; lost of aesthetic values, and inadequate ventilation and lighting. Therefore, government should embark on enforcement of land use plan, and strategic plans for various towns and villages to accommodate its utilities and facilities.

High concentration of contaminants in drinking water can affect human health. This study assessed quality of groundwater at industrial and residential areas of Sango Ota, Ogun State. Water samples were collected in triplicates from 8 wells at industrial and residential areas and analyzed for its physicochemical properties. The pH, electrical conductivity, total dissolved solid (TDS), nitrate, sulphate, total suspended solid (TSS), total hardness (TH), iron, zinc, copper, lead, nickel, chromium and cadmium concentrations in the water samples were determined following American Public Health Association (APHA) procedure. Results showed that pH of 50 % of the wells were lower than minimum limit of 6.5 recommended by WHO. Sulphate, TH and iron in the water were significantly (p < 0.05) higher at residential area than industrial area. Electrical conductivity exhibited significant (p < 0.01) correlation with TDS (r = 0.701**) and NO32- (r = 0.922**) at residential area. At the industrial area however, concentration of salts in water samples was highly associated with SO42- (r = 0.864**) and Cd (r = 0.587**). Across locations of groundwater, iron and lead were above allowable WHO limits in drinking water. Cadmium was also above drinking limit at location T4 of the residential area. Consumers of groundwater in the study area are prone to health related challenges of heavy metal toxicity.

A simplified version of the territory mapping method was used. Four counts were conducted in a fragment of the city of Wrocław in the spring and early summer 2010. Two main urban habitats were distinguished: a densely built-up area with block buildings and a residential area with flat houses. In total, 44 bird species were recorded as breeding in the whole study area. Five species nested in a density higher than 10 pairs per 100 ha each: Columba palumbus, Pica pica, Streptopelia decaocto, Sylvia atricapilla, and Turdus merula. Whereas in the densely built-up areas Columba palumbus and Streptopelia decaocto were equally common, in the residential area Streptopelia decaocto was almost three times more common than Columba palumbus. Pica pica was about three times more common than Corvus cornix both in the builtup areas and in the residential areas. Although densely built-up areas and residential areas have a similar species composition, many species breed in different densities. This is probably due to a different structure of vegetation. While tall trees are relatively common and shrubs rare in the densely built-up areas, the reverse situation prevails in residential areas.

Sites of oppression might be remembered in ways that contribute to dialogues about human rights and justice, exemplified by Sites of Conscience. Oppression was commonplace in former psychiatric institutions, yet such institutions are often subject to strategic forgetting and transformed into business parks, hotels, or residential areas. This article concerns Långbro Hospital, a digital museum presenting the former psychiatric institution Långbro, Sweden, now transformed into a residential area. I discuss how the former institution becomes a digital nonplace in which patients tend to be objectified or excluded, and the park and the buildings in which oppression occurred are reduced to representing beauty and functionality. I relate the analysis to digital Sites of Conscience such as British Museum of Colonialism and Pennhurst Memorial and Preservation Alliance and, thereby, show that thoughtful digitization might recognize prior as well as current injustice and oppression and contribute to change.
