Land transformation in agriculture is a crucial global issue for food safety and regional sustainable development. In the context of Chinese rural revitalization strategy, farmland transfer has become an increasingly engaging area of focus for those in a broad range of fields. In this paper, we make a comprehensive review of land transformation in agriculture through literature analysis. Farmland transfers in China were characterized as five dimensions: public policy, market mechanisms, influencing factors, optimization of spatial distribution, and practical results. Meanwhile, we shed light on limitations of the theories and methodologies for farmland transfers in previous studies, and propose the highlights of farmland transfers in China in the future: (1) refining the theoretical systems of farmland transfer under the background of transformations, (2) optimizing land use configuration for farmland transfers within the context of national strategic decisions, (3) developing the land use model supported by big data for understanding farmland transformation; (4) enhancing the comprehensive analysis and interdisciplinary application perspective for farmland transfer issues.

Autonomous vehicles (AVs) can generate major changes in urban systems due to their ability to use road infrastructures more efficiently and shorten trip times. However, there is great uncertainty about these effects and about whether the use of these vehicles will continue to be private, in continuity with the current paradigm, or whether they will become shared (carsharing/ridesharing). In order to try to shed light on these matters, the use of a scenario-based methodology and the evaluation of the scenarios using a land use–transport interaction model (LUTI model TRANSPACE) is proposed. This model allows simulating the impacts that changes in the transport system can generate on the location of households and companies oriented to local demand and accessibility conditions. The obtained results allow us to state that, if AVs would generate a significant increase in the capacity of urban and interurban road infrastructures, the impacts on mobility and on the location of activities could be positive, with a decrease in the distances traveled, trip times, and no evidence of significant urban sprawl processes. However, if these increases in capacity are accompanied by a large augment in the demand for shared journeys by new users (young, elderly) or empty journeys, the positive effects could disappear. Thus, this scenario would imply an increase in trip times, reduced accessibilities, and longer average distances traveled, all of which could cause the unwanted effect of expelling activities from the consolidated urban center.

The Impact

This book examines the impact of planning politics on the public interest by focusing on the case of Montgomery County and its land use policy. In particular, it considers Montgomery's pioneering approach to inclusionary zoning, the Moderate-Priced Dwelling Unit Ordinance, in terms of its effect on development patterns and the character and cost of housing. Montgomery was among the earliest fast-growing suburbs to stage development concurrently with the provision of public facilities. Its land use policies were efforts by the county's planners and politicians to solve practical problems in the public interest. The book analyzes the chain of strategic decisions that transformed Montgomery County from a rural hinterland of Washington, D.C. into a socially diverse urbanizing county of a million people in Maryland. This introduction provides an overview of the growth of suburbs and its implications for neighborhoods and residents, Montgomery County's suburbanization, and the organization of the book.

<p><strong>Abstract.</strong> The primary issues related the spatial organization of urban settlements are based on the development of density and land use decisions leading due to the market mechanisms. The current spatial land use pattern of cities have emerged depending various factors such as the migration movements increased rapidly from the 1950s, the rapid and uncontrolled urbanization, the pressures of rent directing the market mechanisms, etc. This urbanization process also has accompanied many problems as the insecure construction for disasters, dense and solid urban texture, various weaknesses or deficiencies of urban infrastructure. As a consequence of the evaluation for social facility areas (gaps in urban area, open and green areas, etc.) as “potential investment areas”, the loss of solid &amp;ndash; void ratio and dense built-environment have been experienced in urban centres and also urban development directions. The main aim of this study is to examine the spatial effects of land use decisions between the years of 2002 &amp;ndash; 2017 under the influence of the Law 6360 in terms of urban planning discipline. These spatial variations related land use pattern are determined using Google Earth and Geographical Information Systems (GIS). According to the results, it is clearly understood that current land use patterns in Guzelbahce district have changed significantly in 15-years period. The results of analyses related the case area which the urban sprawl has seen are discussed and a variety of policies have been developed.</p>

Single Configuration

Red teaming is the process of studying a problem by anticipating adversary behaviors. When done in simulations, the behavior space is divided into two groups: one controlled by the red team, which represents the set of adversary behaviors or bad guys; the other controlled by the blue team, which represents the set of defenders or good guys. Through red teaming, analysts can learn about the future by forward prediction of scenarios. More recently, defense has been looking at evolutionary computation methods in red teaming. The fitness function in these systems is highly stochastic, where a single configuration can result in multiple outcomes. Operational, tactical and strategic decisions can be made based on the findings of the evolutionary method in use. Therefore, there is an urgent need to understand the nature of these problems and the role of the stochastic fitness to gain insight into the possible performance of different methods. This chapter presents a first attempt at characterizing the search space difficulties in red teaming to shed light on the expected performance of the evolutionary method in stochastic environments.

PurposeThe purpose of this paper is to integrate land use and option pricing theories using case study analyses to compare a portfolio of uses comprising single and mixed‐use development on the same site and assess the effects on the risk‐return profile of potential development schemes. The integration of land use development based on highest and best use (HBU) is tested against a combination of uses on the selected sites at a point in time in the downswing of the real estate cycle.Design/methodology/approachThe proposed methodology integrates the development valuation approach with option theory in which both consider the relationships of cost and value associated with alternative development options. The approach used in this paper addresses the broader consideration of project coordination inclusive of land use flexibility and opportunity costs endogenously associated with development strategies. By investigating the uncertainty of economic options specific to the development process, the methodology considers the significance of complementary components of strategic decisions and entrepreneurial effort within a return/risk management strategy.FindingsThe stochastic model when compared to the real option model enhances strategic decisions and development project management by allowing the consideration of single/mixed‐use alternatives. The development process is facilitated by the research findings whereby alternative uses are tested to maximise the potential use of the site. The analyses consider optimal funding strategies in developing and investing for a range of use options on regeneration sites.Practical implicationsThe significant insights apparent from the research is the quantification of the strategic specification of development as a productive process and an investment endeavour. The proposed model enables a comparison of a HBU based on a single development, a mixed‐use development or a combination of uses as the difference between the scenarios impacts on land value and profit measures, especially where these measures are calculated as distributive residuals.Originality/valueThe stochastic model developed in this paper provides a value‐added contribution to real estate literature by considering the complexity of the interrelationships between urban land economics, land use theory, valuation appraisal methodologies, portfolio analysis and option pricing as applied in the development of regeneration schemes.

This chapter discusses the changes to the regime of landownership and land use in the decades following annexation. In the second half of the eighteenth century, officials and scholars alike were developing new methods of quantifying Russian terrain. In their deployment of the cadastral survey and estate mapping and the compilation of statistics, they helped standardize the management and definition of imperial space. However, their efforts also cultivated an increasing awareness of the value and idiosyncrasies of micro-landscapes and shed light on differences in the cultural understanding of landownership in Russia and the former khanate. The chapter then shows how imperial officials, Russian pomeshchiki (landowners), and Crimean Tatars used landownership practices to shore up social and political hierarchies.
