AbstractUrban sprawl has been widely discussed in regard of its economic, political, social and environmental impacts. Consequently, several planning policies have been placed to stop—or at least restrain—sprawling development. However, most of these policies have not been successful at all as anti-sprawl policies partially address only a few determinants of a multifaceted phenomenon. This includes processes of extended suburbanisation, peri-urbanisation and transformation of fringe/belt areas of city-regions. Using as a case study the capital city of Chile—Santiago—thirteen determinants of urban sprawl are identified as interlinked at the point of defining Santiago's sprawling geography as a distinctive space that deserves planning and policy approaches in its own right. Unpacking these determinants and the policy context within which they operate is important to better inform the design and implementation of more comprehensive policy frameworks to manage urban sprawl and its impacts.

Urban sprawl is one of the most important problems in urban development due to its negative environmental and societal impacts. Therefore, the spatial pattern of urban growth should be accurately analyzed and well understood for effective urban planning. This paper focuses on urban sprawl analysis in the Atakum, Ilkadim and Canik districts of Samsun, Turkey. In this study, urban sprawl was examined over a period of 24 years using Shannon's entropy and fractal analysis based on remote sensing and Geographic Information System (GIS). The built-up areas in 1989, 2000 and 2013 were extracted from Landsat TM/ETM+/OLI images using the maximum likelihood classification method, and urban form changes in the 1989–2013 period were investigated. The Shannon's entropy method was used to determine the degree of urban sprawl, and a fractal analysis method based on box counting was used to characterize the urban sprawl. The results show that Atakum, Ilkadim and Canik experienced important changes and have considerable sprawl and complex characteristics now. The study also revealed that there is no monotonic relationship between Shannon's entropy and fractal dimension.

This case study presents the design, operation, and results of a soil improvement project using the vacuum preloading method on 480 000 m2 of reclaimed land in Xingang Port, Tianjing, China. The areas treated with vacuum ranged from 5000 to 30 000 m2. The effects of soil improvement are demonstrated through the average consolidation settlement of 2.0 m and increases in undrained shear strengths by a factor of two to four or more. The study shows that the vacuum method is an effective tool for the consolidation of very soft, highly compressive clayey soils over a large area. The technique is especially feasible in cases where there is a lack of surcharge loading fills, extremely low shear strength, soft ground adjacent to critical slopes, and access to a power supply.Key words: vacuum preloading consolidation, soil improvement, soft clays, land reclamation, prefabricated vertical drains.

Urban sprawl has been plaguing Western European and American cities for the last 70 years. One has fought against this phenomenon all over the world with a combination of strategic planning and urban regulations, focusing on growth management, sustainable development and preservation of farmland. East European cities, Romanian cities included, have been rapaciously consuming the free natural and agricultural land around them, without long-term development policies. The aim of this paper is analyzing urban sprawl around Timișoara and finding efficient ways of economizing urban and rural land. The article is based on several urban studies, statistical and traffic data showing the magnitude of the phenomenon and its dramatic effects on the environment.The European Union required to recent members to follow the path set by the developed countries, even if their economies have a system more or less centralized inherited from communism. It is still unclear who should be responsible for urban planning; the rules and regulations are made along the way, while the investors’ pressure is huge. Meanwhile extended rural and agricultural land might be destroyed. Most politicians do not acknowledge this problem as they approve further expansion into farmland without any previous planning. This paper might be just tackling this subject, but its target should be making urban sprawl more visible, understanding its dimension and dramatic effects around Romanian cities.

The Municipality of Velika Plana has been taking serious steps when it comes to initiating landconsolidation projects which help realize the land reclamation projects in the simplest way. Whit theaim of obtaining the base for carrying out land reclamation projects, this work deals with and presentsthe survey of the hydrographic features of Municipality of Velika Plana, as well as, water regime andthe river basin of the Velika Morava River. Based on measuring data obtained at Ljubicevski most,water gauge survey station we have performed and presented the analysis of the distinctive annual flowover a longer period of time as well as the analysis related to the changes in parameters which occur onan annual basis. On the basis of performed analysis we have been able to determine the amounts ofwater for irrigation available in the Velika Morava River basin at the territory of Velika Plana, whichwas the main focus and objective of this research.

ABSTRACTThis study aims to: (1) find out what factors influence farmers' decisions in transferring land functions, and (2) formulate control strategies for land conversion. The method used in this study is a case study method, which is the sample unit is farmers who are still planting paddy fields and farmers who have converted land into oil palm plantations. Data analysis method to answer the first problem using logistic regression analysis, while to answer the second problem using SWOT-Classic analysis. The conclusions of this study are (1) the factors that significantly influence the decision of farmers in transferring land functions are income, production costs and education level, (2) the formulation of strategies that can be recommended based on the results of the SWOT analysis conducted as follows: (a) determine the rice field area of food crops in each village in Tanjung Lago Subdistrict, accompanied by socialization of land conversion rules, (b) Make improvements to the tidal land reclamation network in Tanjung Lago sub-district and encourage farmer groups in network management tidal land reclamation.ABSTRAK Penelitian ini bertujuan untuk : (1) mengetahui factor apa saja yang berpengaruh terhadap keputusan petani dalam melakukan alih fungsi lahan, dan (2) merumuskan strategi pengendalian alih fungsi lahan.
