There is a need for indicators of transportation–land use system quality that are understandable to a wide range of stakeholders and that can provide immediate feedback on the quality of interactively designed scenarios. Location-based accessibility indicators are promising candidates, but indicator values can vary strongly depending on time of day and transfer wait times. Capturing this variation increases complexity, slowing calculations. This paper presents new methods for rapid yet rigorous computation of accessibility metrics, allowing immediate feedback during early-stage transit planning while being rigorous enough for final analyses. The approach is statistical, characterizing the uncertainty and variability in accessibility metrics related to differences in departure time and headway-based scenario specification. The analysis was carried out on a detailed multimodal network model including both public transportation and streets. Land use data were represented at high resolution. These methods were implemented as open-source software running on a commodity cloud infrastructure. Networks were constructed from standard open data sources, and scenarios were built in a map-based web interface. A case study is presented, describing how these methods were applied in a long-term transportation planning process for an urbanized, polycentric Randstad region in the Netherlands.

Rail System

The rail system generates an increase in accessibility by reducing transport costs and travel times. It also has an economically positive return to urban areas for public transport investments. Such public transportation investments; it is important for the planning process to know the effects of changes in land use, income, employment, intensity and monetary values. In this study, for the "Kazlıçeşme - Söğütlüçeşme Subway Line (1st Stage)", taxable gains for the years 2022-2038 are explained and linear increase rates are found. Areas with potential for real estate investment and transformation around the stations were examined and the exchange potentials and land use possibilities of residential areas were investigated. According to the findings of the study, the increase in real estate tax will reach up to four times; at the same time it was determined that there would be an increase in land-use attraction in the recreation, commercial and residential etc. areas around 14 stations.Extended English summary is in the end of Full Text PDF (TURKISH) file. ÖzetRaylı sistem toplu taşıma yatırımlarının kentsel alanlara ekonomik açıdan pozitif getirileri olmakla birlikte, ulaşım maliyetlerinin ve seyahat zamanlarının azalmasını sağlayarak erişilebilirlik artışı oluşturmaktadır.

The Impact

AbstractMoving along with daily life, urban residents and commuters create characteristic spatiotemporal patterns which vary extensively with the time of day. These patterns are formed via traffic flows: accordingly, understanding the impact of transportation system is essential for urban planners to evaluate expected urban activities. To explore them, we examine specifically population distributions in Seoul City by analyzing hourly population data based on mobile phone location records in combination with a couple of indicators of the Seoul Subway system. Through clustering and principal component analyses, we first demonstrate that the spatial distribution of the population is categorized according to the time of day, i.e., night, daytime, and evening, variations across which reflect the morphology of land use. We then examine the influence of the subway system on the population, employing ridership and accessibility as indicators. Our linear regression analysis shows that both are associated with the daytime and the evening populations, which implies that only commercial activities are substantially coupled to the subway system. Further, we find that the distinctive difference of night population is encoded in the probability distributions; this is elucidated by means of a multiplicative growth model for the morphological evolution of Seoul, revealing decentralization of residential areas and centralization of commercial areas. This study sheds light on the interplay of a public transportation system and land use, which is of relevance to planners and policymakers wishing to develop neighborhoods in support of sustainable modes.

Digital Earth Africa is now providing an operational Sentinel-1 normalized radar backscatter dataset for Africa. This is the first free and open continental scale analysis ready data of this kind that has been developed to be compliant with the CEOS Analysis Ready Data for Land (CARD4L) specification for normalized radar backscatter (NRB) products. Partnership with Sinergise, a European geospatial company and Earth observation data provider, has ensured this dataset is produced efficiently in the cloud infrastructure and can be sustained in the long term. The workflow applies radiometric terrain correction (RTC) to the Sentinel-1 ground range detected (GRD) product, using the Copernicus 30 m digital elevation model (DEM). The method is used to generate data for a range of sites around the world and has been validated as producing good results. This dataset over Africa is made available publicly as a AWS public dataset and can be accessed through the Digital Earth Africa platform and its Open Data Cube API. We expect this dataset to support a wide range of applications, including natural resource monitoring, agriculture, and land cover mapping across Africa.

ABSTRACT Net Environmental Benefit Analysis (NEBA) is increasingly used as a framework to assess the environmental benefits and disadvantages of a chosen response action. This analysis can be used to account for political and economic impacts as well as the effects on the natural environment. Until recently the discussion has focused on qualitative assessments due to the lack of quantitative information collected at spills. This paper uses examples of best practice of NEBA from different spills around the world to outline the information that should be collected at future spills in order to determine the level of Net Environmental Benefit that has been achieved by the response operation. In the first instance immediate feedback may well provide information which aids decision making at the time of the incident. However, a key role for this information is also to enable responders around the world to establish best practice for a wide range of environmental sensitivities. Case histories of Net Environmental Benefits will provide a basis for the overall contingency planning process, recognising that post-spill decisions are best and most rapidly made in the light of pre-spill analyses, consultations and agreements by all the appropriate organisations.

Interest in land-use changes (LUC) research has been growing rapidly in recent years. This topic has already become the subject of a separate scientific discipline – land use science (or land change science). In order to formulate relevant future policy and develop appropriate land-use management tools, it is crucial to know how the LUC шьзфсе the environment and society condition. For Ukraine, where the structure of land use and the system of land resources management have significantly changed during the years of post-socialist transformation of land relations, the study of the LUC on a modern methodological basis is especially actual. The paper, based on a critical analysis of publications in leading international journals over the last thirty years, identifies key directions of LUC studies and analyzes their methodological features. There is a significant increase of the number of works based on the results of meta-studies and the use of a wide range of methods for modeling the LUC processes, their causes and possible consequences. The great "synergistic potential" of integration of the selected directions is noted, which makes it possible to accelerate the development of the general theory of land use and increase its use efficiency in substantiation of management decisions in the sphere of land use and modernization of the mechanisms of state land, spatial and ecological policies with consideration of existing and potential globalizing challenges. In this context, the key role of the land use integrated planning methodology at regional and local levels is emphasized. This methodology would require close cooperation between government, business and the public in developing a common vision for the implementation of specific land use plans and projects based on the principles of subsidiarity, participativity and shared responsibility.

Land Use Development

The land and town planning legislation concerning the planning of land use development within the united territorial communities (UTC) is considered. It is found that legislative norms need to be finalized. The necessity of updating the existing land management documentation developed prior to the adoption of the Law of Ukraine "On Land Management" and changes in the structure of urban development in connection with the adoption of the Law of Ukraine "On Regulation of Urban Development" was proved as they do not ensure the integrity of the planning process within the territories of these communities through their institutional incapacity (proved by the example of the Palan Unified Territorial Community of the Uman district of the Cherkasy region). The priority of land management and urban planning documents as the most influential tools in planning the development of land use systems in UTC is scientifically grounded and their interdependence established.

Annapurna Conservation Area

Conservation areas are originally well-known for protecting landscape features and wildlife. They are playing key role in conserving and providing a wide range of ecosystem services, social, economic and cultural benefits as well as vital places for climate mitigation and adaptation. We have analyzed decadal changes in land cover and status of vegetation cover in the conservation area using both national level available data on land use land cover (LULC) changes (1990-2010) and normalized difference vegetation index (NDVI) (2010-2018) in Annapurna conservation area. LULC showed the barren land as the most dominant land cover types in all three different time series 1990, 2000 and 2010 with followed by snow cover, grassland, forest, agriculture and water body. The highest NDVI values were observed at Southern, Southwestern and Southeastern part of conservation area consisting of forest area, shrub land and grassland while toward low to negative in the upper middle to the Northern part of the conservation area.

The ability to detect nanoscale objects is particular crucial for a wide range of applications, such as environmental protection, early-stage disease diagnosis and drug discovery. Photonic crystal nanobeam cavity (PCNC) sensors have attracted great attention due to high-quality factors and small-mode volumes (Q/V) and good on-chip integrability with optical waveguides/circuits. In this review, we focus on nanoscale optical sensing based on PCNC sensors, including ultrahigh figure of merit (FOM) sensing, single nanoparticle trapping, label-free molecule detection and an integrated sensor array for multiplexed sensing. We believe that the PCNC sensors featuring ultracompact footprint, high monolithic integration capability, fast response and ultrahigh sensitivity sensing ability, etc., will provide a promising platform for further developing lab-on-a-chip devices for biosensing and other functionalities.
