Biodiversity has declined in many areas because of human activities and loss of habitats. The Watershed of Arak University with a total area of 625.65 hectares is located on the southwestern slope of Mount Mudar, northwest, adjacent of Arak city and north of Karahrod. Biodiversity information of the area was collected with using linear transect and dotted transect methods by installing camera trap, camera and GPS. The results indicate that biodiversity history dates back more than 65 million years. Currently, lives 55 species of dominant rangeland species and 50 species of animal include: 34 species of birds, 10 species of mammals and 6 species of reptiles and amphibians in the area. Falcon and Fritillaria are the Endangered (EN) and Greek tortoise and persian toad agama are the Vulnerability (VU). The most important threats to biodiversity include are development of the city of Arak in the region, habitat destruction, uncontrolled hunting, livestock and dogs, road construction and the abandonment of habitats with surrounding habitats, feeding wildlife from urban waste, nature tourism and informal climbing.

Indonesia has a lot of potential for nature tourism in the form of mountains, sea, and beaches. This is also an attraction for tourists to make Indonesia as the preferred natural tourist destination when on vacation. Especially West Java, West Java is one of the provinces that are in great demand by local and outside tourists.Besides being famous for its local culture and its unique culinary variety, West Java is also known for its cool air, especially in some parts that are still preserved in nature, the natural potential that is still good and is maintained as an attraction for West Java to attract tourists. One of the famous areas in the city of Bandung which is a tourist destination is the Lembang Region.From the last five years the lodging area in Lembang has increased, currently in Lembang sub-district itself has 13 lodging units in the form of resorts. The amount itself is influenced by the high demand for lodging accommodation especially when the holiday season arrives. But of that number, resorts that have complete and well-maintained facilities and conditions are still not completely even. Based on this fact, the purpose of designing this resort is expected to be the best tourist area in the region to be able to adjust to the conditions of the land conditions, be able to use and not damage the existing land on the design land.The study used in this design is based on the description that occurs today with the support of the literature that supports the theory and analysis that is done. Implementation analysis was carried out using macro and microanalysis methods. Macro analysis is an analysis on a regional scale. While microanalysis is an analysis of the design site, which includes activity analysis, function analysis, space analysis, site analysis, shape analysis, and display and structural analysis and utility.The concept of site and building in this design will produce a conceptual relationship that will later become a guideline in making a design. This concept includes the proposed concept of site design, form, structure, and utility.

AbstractWastes from the cities and villages cannot be avoided from man's existence. It is essential to safely put these unwanted or discarded material away, in the interest of the community. During human activities a lot of waste matter is produced due to various development project, industrialization and modernization of the community. In this study waste materials were collected from various hospitals and rural and urban residential areas. These wastes were divided into two main categories- Health care waste and domestic waste. The survey indicated 80% solid waste deals with the domestic and urban waste while only 20% deals with the health care waste. The health care waste is regarded hazardous and may cause a variety of health risk.

Invasive alien species (IAS) is a global problem that largely relates to human activities and human settlements. To prevent the further spread of IAS, we first need to know their pattern of distribution, to determine which constitutes the greatest threat, and understand which habitats and migration pathways they prefer. Our research aimed to identify the main vectors and distribution pattern of IAS of plants in the city environment. We checked the relations between species distribution and such environmental factors as urban soil type and habitat type. We applied data on IAS occurrence (collected in the period 1973–2015) in 515 permanent plots with dimensions of 0.5 × 0.5 km and analyzed by direct ordination methods. In total, we recorded 66 IAS. We found a 27% variance in the IAS distribution pattern, which can be explained by statistically significant soil and habitat types. The most important for species distribution were: river and alluvial soils, forests and related rusty soils, and places of intensive human activities, including areas of urbisols and industriosols. Our results provide details that can inform local efforts for the management and control of invasive species, and they provide evidence of the different associations between natural patterns and human land use.

The existence of construction in an area will have an influence on regional development. Likewise in the City of Magelang, the construction sector is a sector that contributes a fairly large GRDP with the construction of construction such as buildings and roads as the provision of facilities and infrastructure will result in an increase in community welfare which will also affect economic growth. The purpose of this study was identif construction sector in the form of roads and buildings with the results of a map of the distribution of construction in the City of Magelang by looking at the local construction service company so that it can be a reference in improving regional development, especially the construction sector to realize adequate infrastructure. As well as the socio-economic benefits of having a construction service company in Magelang City. This study used qualitative descriptive method with questionnaire, interview, observation and observation techniques. In the 2020 construction distribution map, there are high, medium and low building densities where high building densities dominate in the middle of the city along the main road. Road construction helps the distribution of goods and services and maximizes community access. The existence of a local construction service company provides benefits to the community both socially and economically, such as employment, services, and improvement of infrastructure facilities for the community. However, stronger synergy is needed to realize quality construction and utilize local resources in its implementation.

Context: Like many sub Saharan African cities, Yaoundé is experiencing a faster growth of its population and urban perimeter. The urban population has grown from 812 000 inhabitants in 1987 to 2 100 000 inhabitants in 2006. However, this population growth has not been monitored by the city planners and decision makers. Accordingly, the city is lacking basic urban facilities. such as a good sewage system to evacuate urban waste water. Objective: This paper aims at addressing health consequences resulting from inadequate management of rainwater in Yaoundé. Material and methods: From the data gathered by us in the framework of the PERSAN programme focused on urban health, a cross sectional study has been carried out in 2002 and 2006 across the city. Based on socio-environmental and medical surveys, the study covered neighborhoods and 3 034 households in Yaoundé. Results: It comes out that that the present urban draining network is outdated and ineffective. This has led to increasing fl oods in several sectors of the city, with health hazards. It has been noted that many diarrheal diseases in Yaoundé are related to the poor sanitation resulting from urban waste coupled with standing waters. Conclusion: We are of the opinion that to solve this problem, there is urgent need to set up a new town-planning mechanism which takes into account the city’s demographic and space dynamics.

Abstract The great forest of Zakour is located north of the commune of Mamounia (department of Mascara). It is considered the lung of the city of Mascara, covers an area of 126.8 ha. It is a forest that is subject to several natural and human constraints. Among them, the fires are a major danger because of their impacts on forest ecosystems. The purpose of this work is to develop a fire risk map of the Zakour Forest through the contribution of geomatics according to natural and anthropogenic conditions (human activities, agglomeration, agricultural land) while integrating information from ground on the physiognomy of the vegetation. For this, the creation of a clearer fire risk map to delimit the zones potentially sensitive to forest fires in the forest area of Zakour. This then allows good implementation of detection management plans, for better prevention and decision-making assistance in protecting and fighting forest fires.

Town planning is a comprehensive task involving several stages that takes the city from actual state it is in to a desired state in the future through various measures taken by the concerned planning authorities. A city may be viewed as a system or a complex whole consisting of different component parts related or interacting with one another so as to form a unity. The component parts of the systenl consists of persistent human activities that have a tendency to occur or recur at specific locations that is, the activities occur within adopted spaces which include buildings, parks, water, bodies etc. The co~l~leclionasm ong these parts are communications which enable various activities to inter;ict so that necessary patterns of huinan behaviour can occur. These communications are recurrent and spatially clustered such as roads, railn~aysp, ipelines, cables etc. Implemelltation of the plan involves control of the various components of thissystenl so that the intended state as set out by the goals of the plan would depend on the existing state of the city. Therefore a thorough knowledge of the present state of the city is the first and an ilnportant step in any planning process.

Bangkok, the capital of Thailand, is situated on flat, low land in the southern part of the Central Plain, one of the main physical units of the country. Through the heart of the city, the Chao Phraya flows from the north and discharges into the Gulf of Thailand, 25 km south of the city centre. The city was founded in 1782, and in its early years numerous klongs (canals) were dug for transportation and defence uses. These canals became corridors of early development, and banks were lined with houses, shop-houses, and temples, etc. With the beauty of its waterway landscape, Bangkok was once dubbed the Venice of the East. Unfortunately, such a resemblance no longer exists as most of the canals have been backfilled to make room for road construction in recent urbanization. The Bangkok metropolis, which at present has a population in excess of 10 million, has expanded rapidly on both banks of the river since 1950. It has encroached into surrounding provinces, covering an area of approximately 60 × 70 km. Owing to its flat topography and close proximity to the sea, flooding threatens the city annually. Modern urbanization has resulted in the drastic destruction or blockage of natural drainage paths, increasing the flood risk to the city. Severe land subsidence from excessive groundwater extraction since the 1960s has intensified the flood risk, as well as creating numerous foundation problems. At present the land surface in some areas is already below mean sea level. The city now has to rely on a flood protection system to prevent inundation. However, its effectiveness is only temporary because land subsidence has not yet ceased. The Central Plain is formed by the Chao Phraya River, the largest in the country. The river basin stretches from the Northern Highland to the Central Plain and covers about one-third of the country (514 000 km2). The Central Plain can be divided into the Upper and Lower Central Plains. The former extends from Tak to Nakhon Sawan Provinces. Four main rivers, namely, the Ping, the Wang, the Yom, and the Nan, which originate in the Northern Highland, traverse the plain and join together at Nakhon Sawan, 240 km north of Bangkok, to form the Chao Phraya River.

The ongoing recession has provided new layers in the tangible and intangible palimpsests in the city of Athens, especially in its neglected urban pockets that can be central but always outside the city’s normal, social life. This article arises from my experience of participating in a cleaning activity under the Anapafseos Street Bridge over the encased Ilissos River in central Athens in September 2010. In it I challenge the official rhetoric regarding the use of marginal sites for parasitic activities, by re-appropriating urban waste into empirical evidence and attempting to read through the lines of the graffiti left behind by a community of migrants that used the bridge as a temporary camp site. By providing an alternative reading of the bridge as an in-between place, this article seeks to problematize the assimilation of hidden communities in the city. It can also be considered as a gesture of contemporary-urban archaeology, a way to both approach and understand these communities in a form of a publicly engaged and politically relevant archaeological practice.
