This article evaluates the tendencies and impact of urbanization on the land use within the Chisinau agglomeration. The research carried out regarding Stăuceni commune, confirms that the periurban area, undergoes a period of significant spatial and functional transformation, influenced by the demographic pressure, poorly controlled urban development and the intensification of the land relations. By implementing the project “Chisinau Arena” on the territory of Stăuceni commune, the plan for territorial expansion of Chisinau city (in peri-urban areas located on major transport axes) is reconfirmed. At the same time, the demographic forecast presented in scenario III, according to UN for population, shows that the Chisinau population will decrease dramatically, towards 2035, therefore it is necessary that the spatial planning plans to be adapted quickly to the pace of demographic changes, to avoid compromising the infrastructure projects and squandering land in the suburban areas.

Spatial planning plays an important role in cropland protection, but its effectiveness is often questioned in the face of ongoing urban and infrastructure growth. Moreover, methods to assess the effectiveness of spatial planning are lacking. In Switzerland, the revision of the national spatial planning act in 2014 was a new starting point for stricter prescriptions on urban development. We assessed whether the new regulations would better protect dedicated prime cropland from conversion to urban areas using land-use suitability models and land-use scenarios. The findings show that with the planning according to the revised planning act, the potential consumption of prime cropland for new urban areas is six times smaller than that occurring through extrapolation of the observed trend in urban development over the past 25 years. However, scenario modeling suggests that, still, more prime cropland will be converted into urban areas than necessary, and that it may be difficult to protect prime cropland to the extent mandated by the Swiss prime cropland protection policy. We have developed an approach to a priori evaluate spatial planning measures. However, the strict implementation of these planning measures will be needed in order to maintain prime cropland to a level required for agricultural self-sufficiency and food security.

Suburbanization affects on spatial planning and transport policy in urban areas. The main theme of this report is to show how the transport network react to the chaotic and dynamic growth of suburban areas. Authors show spatial growth on three examples. The paper also tries to prove that with the growing trend toward suburbanization, more effective transportation systems must be developed to meet the needs of the low-density, suburban population. Authors refer to the process of suburbanization onexamples from Wroclaw and the surrounding locality.

Abstract An autonomous unmanned helicopter (AUH) survey is a useful tool for monitoring the distribution of ambient dose equivalent rates. However, the AUH survey method was developed for plane permeable fields such as agricultural land, and its applicability to urban areas is unclear. In this study, the applicability was investigated by comparing the results of AUH and ground-based surveys conducted in suburban areas, including residential and agricultural lands. The results of both surveys broadly agreed with each other within a factor of 2 in the range independent of land use, and the factor was the same as that reported for plane permeable fields. These results suggest that AUH surveys are applicable in urban areas. The measurement uncertainty of the AUH survey was largely affected by the patchy and local distribution of ambient dose equivalent rates on the ground and differences in the fields of view, rather than land use.

Abstract Urbanization causes wildlife habitat loss, fragmentation, and the replacement of specialist species by generalists and/or exotic taxa. Because mesocarnivores are particularly vulnerable to habitat modifications, the rapid expansion of urban areas and the increasing trend for ex-urban development occurring in Mediterranean ecosystems may be major drivers of change in mesocarnivore communities. We combined camera trapping and sign surveys to quantify the richness and relative abundance of a set of wild and domestic mesocarnivores. We quantified these variables controlling for the gradient of urbanism, ex-urbanism, and other environmental variables in patches of natural vegetation in the region of Madrid (central Spain), and a non-urbanized control area ~220 km south of Madrid city. Using conditional autoregressive models (CAR) and model selection procedures, we found that urbanization influenced mesocarnivore community composition but this influence was not detrimental for all the species tested. Generalist carnivores such as the red fox Vulpes vulpes were more abundant in urban and ex-urban areas. Ex-urban development creates overlapping areas between wild and domestic species (such as the domestic cat Felis catus and the wildcat Felis silvestris) but contact between wild and domestic carnivores in natural areas is unlikely. Detection of species in the control area was very low. Therefore, the impact of urbanization in causing changes in mesocarnivore communities may be less than other factors such as illegal predator culling.

Quantitative, qualitative and structural changes in land use that occur in a given location over time are a manifestation and a measure of urban development. Urbanisation is a process of spatial diffusion that spreads from the urban core to peripheral areas. Urban development is linked with human activities in a specific location and in a given period of time. In the context of spatial management, urbanisation is a process where less intensive land-use types are replaced by more intensive forms of land use. The demand for new land for residential development, the search for alternative locations for housing construction and the development of sustainable land management plans require new methods that support decision-making in the process of land conversion in peri-urban areas. The aim of this study was to develop a methodology for identifying and localising the boundaries of urban development with the use of the fuzzy set theory and to analyse the rate of changes in land use based on data for 2005–2010–2017. The proposed method supports the identification and localisation of urbanised areas and an evaluation of the degree of urbanisation in the interval [0,1]. The case study was conducted in the Polish city of Olsztyn.

Abstrak. Penyimpangan penggunaan lahan sangat sering terjadi terhadap rencana tata ruang wilayah (RTRW). Daerah pinggiran kota merupakan wilayah yang banyak mengalami perubahan penggunaan lahan terutama perubahan penggunaan lahan pertanian menjadi non pertanian. Adapun tujuan penelitian untuk menganalisis tingkat keselarasan penggunaan lahan basah eksisting di Kecamatan Darul Imarah berdasarkan RTRW. Metode yang digunakan dalam penelitian ini adalah metode deskriptif dengan teknik survai. Sedangkan analisis data spasial menggunakan SIG dengan konsep extract, overlay dan reclassify. Hasil kajian menunjukkan sebesar 583,94 ha (86,68%) sawah eksisting di kawasan kajian telah selaras dengan RTRW dan yang tidak selaras yaitu sebesar 0,15 ha (0,02%). Sementara 89,57 ha (13,3%) sawah eksisting lainnya ditemukan belum selaras dengan RTRW Kabupaten Aceh Besar tahun 2012-2032.The Use of Existing Wetland Analysis Based On Spatial Planning in Peri Urban Area in Banda Aceh (Case study: Darul Imarah Subdistrict Aceh Besar Regency)Abstract. The deviation of land use is very frequent happened to spatial planning. Suburban areas are areas which undergo many changes in land use, especially changes in the use of agricultural land to non-agricultural. The purpose of the research is to analyze the aligned level of the existing wetland use in Darul Imarah sub-district based on spatial planning. The method used in this research was descriptive method with survey technique. While the spatial data analysis was using GIS with extract, overlay and reclassify concept. The result of the study showed that 583.94 ha (86.68%) of the existing fields in the study area were aligned with the RTRW and the non-aligned ones were 0.15 ha (0.02%). Meanwhile, 89.57 ha (13.3%) of other existing rice fields had not been aligned with the spasial planning of Aceh Besar Regency in 2012-2032.

Abstract Urban growth / urban sprawl are the extension of a residential region into the surrounding area. The negative face of urban development is urban sprawl, criticizing the cause of environmental deterioration, growing inequality and diminishing the viability of aesthetic and urban areas. An effective and efficient planning of urban development and changes in land use and its effects on the environment needs, among other important details, details on development trends and patterns. Over the years, several models of urban growth have been developed and used to predict trends of growth. SLEUTH models are used to simulate and predict urban growth and land use transition for 2020-2050 in the City of Dilla (Ethiopia) in the analysis of Geographic Information System (GIS). The word SLEUTH was derived from the model's input image specifications: slope, land cover, exclusion, urban, transport, and Hill shade. Input data preparation used a cumulative time series dataset of 30 years, i.e. 1989, 1999, 2009 and 2019, such as historical topographical maps and satellite imagery. The SLEUTH model uses the parameters of the best fit growth rule by narrowing coefficients in the calibration mode and passing them down to forecast potential urban growth trends, creating different probability maps and LULC maps. The models generated future urban growth pattern predicted in the 31 years' from 2019, there will be nearly 41.14% urban rise in 2020, 52.95% in 2030, 59.91% in 2040 and 64.30% in 2050. In general, the extension of the urban growth trend introduces new spreading centers that are indicative of urban growth.
