Effects of spatial resolution of remotely sensed data on estimating urban impervious surfaces

Journal Articles & Books
december, 2011
China

Impervious surfaces are the result of urbanization that can be explicitly quantified, managed and controlled at each stage of land development. It is a very useful environmental indicator that can be used to measure the impacts of urbanization on surface runoif, water quality, air quality, biodiversity and microclimate. Therefore, accurate estimation of impervious surfaces is critical for urban environmental monitoring, land management, decision-making and urban planning.

Landscape valuation and planning

Journal Articles & Books
december, 2011

Landscape provides amenities and supports recreational, residential and productive activities. It appears both as an economic resource and as a local public good. Landscape economics uses both public economics and spatial economics concepts, but draws some specificity due to the social and cultural dimensions of landscapes. Moreover, it emphasises the role of the enforcement of property rights' devices on landscape dynamics. The latter is crucial for policy makers who have to deal with various topics such as urban sprawl, agriculture policy, territorial governance and local development.

Impact of urbanization and agriculture on the occurrence of bacterial pathogens and stx genes in coastal waterbodies of central California

Journal Articles & Books
december, 2011

Fecal pollution enters coastal waters through multiple routes, many of which originate from land-based activities. Runoff from pervious and impervious land surfaces transports pollutants from land to sea and can cause impairment of coastal ocean waters. To understand how land use practices and water characteristics influence concentrations of fecal indicator bacteria (FIB) and pathogens in natural waters, fourteen coastal streams, rivers, and tidal lagoons, surrounded by variable land use and animal densities, were sampled every six weeks over two years (2008 & 2009).

Effects of urbanization and industrialization on agricultural land use in Shandong Peninsula of China

Journal Articles & Books
december, 2011
China

China is the most populated country in the world with slightly more than half of the population is still living in rural areas. In the past couple of decades, rapid urbanization and industrialization have significantly changed the land use/land cover (LULC) pattern in rural areas, particularly those around the big cities in eastern China. Shandong Peninsula, a traditional agriculture area, also has witnessed rapid urbanization and industrialization.

Greenway Planning Context in Istanbul-Haliç: A Compulsory Intervention into the Historical Green Corridors of Golden Horn

Journal Articles & Books
december, 2011
Europe

In the last two decades, planners and landscape architects have been concerned with the open space planning concept called ‘greenway planning’. This approach aims at nature protection that balances both conservation and growth, creating livable environments and maintaining open spaces. In Istanbul, the functional and spatial connectivity of greenways can protect the local landscape against urbanization and population growth problems. This study aimed to emphasize the natural and cultural heritage in an ecologically based planning approach.

Modeling urban land use change by the integration of cellular automaton and Markov model

Journal Articles & Books
december, 2011
Japan

Spatially land use models are indispensable for sustainable land use planning. This study demonstrates a combined Markov–Cellular Automata model to analyze temporal change and spatial distribution of land use stressed by natural and socioeconomic factors in Saga, Japan. Firstly, area change and spatial distribution of land use are calculated using GIS technology, and then the transition among different land use types is analyzed to obtain the transformation matrices during a period of 1976–2006.

Turkey’s globally important biodiversity in crisis

Turkey (Türkiye) lies at the nexus of Europe, the Middle East, Central Asia and Africa. Turkey’s location, mountains, and its encirclement by three seas have resulted in high terrestrial, fresh water, and marine biodiversity. Most of Turkey’s land area is covered by one of three biodiversity hotspots (Caucasus, Irano-Anatolian, and Mediterranean). Of over 9000 known native vascular plant species, one third are endemic.

Toward understanding the behavior of carbon dioxide and surface energy fluxes in the urbanized semi-arid Salt Lake Valley, Utah, USA

Journal Articles & Books
december, 2011
United States of America

This paper describes the Salt Lake Valley urban flux study that was designed to understand the role of vegetation and urbanization on CO₂ and surface energy fluxes over surfaces typical of urbanized and pre-urbanized land cover in the semi-arid Salt Lake Valley. The eddy covariance technique was applied at two different sites with distinct land forms within an urbanizing mountain basin.

systematic review of built environment factors related to physical activity and obesity risk: implications for smart growth urban planning

Journal Articles & Books
december, 2011

Smart growth is an approach to urban planning that provides a framework for making community development decisions. Despite its growing use, it is not known whether smart growth can impact physical activity. This review utilizes existing built environment research on factors that have been used in smart growth planning to determine whether they are associated with physical activity or body mass.

automated land subdivision tool for urban and regional planning: Concepts, implementation and testing

Journal Articles & Books

Australia

Simulation of the land subdivision process is useful in many applied and research areas. Planners use such tools to understand potential impacts of planning regulations prior to their implementation. While the credibility of both land-use change and urban growth models would be enhanced by integrating capabilities to simulate land subdivision, such research is lacking in the published literature. Of the few subdivision tools that exist, most are either not fully-automated or are unable to generate realistic subdivision layouts.

Latin America and the Caribbean

This toolkit is the first of its kind to provide information on promoting and protecting the nutritional status of mothers and children in crises and emergencies. Latin America and the Caribbean is one of the most vulnerable regions in the world to major crises and emergencies. This toolkit aims to improve the resilience of the most vulnerable in times of intensified nutritional needs, most notably pregnant and lactating mothers as well as children less than two years of age.
