Response of dissolved trace metals to land use/land cover and their source apportionment using a receptor model in a subtropic river, China

Journal Articles & Books
december, 2011
China

Water samples were collected for determination of dissolved trace metals in 56 sampling sites throughout the upper Han River, China. Multivariate statistical analyses including correlation analysis, stepwise multiple linear regression models, and principal component and factor analysis (PCA/FA) were employed to examine the land use influences on trace metals, and a receptor model of factor analysis-multiple linear regression (FA-MLR) was used for source identification/apportionment of anthropogenic heavy metals in the surface water of the River.

Water Right Prices in the Rio Grande: Analysis and Policy Implications

Journal Articles & Books
december, 2011
Northern America

Climate change, water supply limits, growing environmental values of water and worldwide population growth continue to raise the scarcity of water. These challenges have intensified the transfer of water from farms to cities. Water right transfers are an important international institution to stretch water supplies. In North America's Rio Grande Basin water right transfers are an especially important institution for meeting the growth in urban demands.

Land use and land cover changes over a century (1914–2007) in the Neyyar River Basin, Kerala: a remote sensing and GIS approach

India

Land use and land cover change, perhaps the most significant anthropogenic disturbance to the environment, mainly due to rapid urbanization/industrialization and large scale agricultural activities. In this paper, an attempt has been made to appraise land use/land cover changes over a century (1914–2007) in the Neyyar River Basin (L=56 km; Area = 483.4 km²) in southern Kerala – a biodiversity hot spot in Peninsular India.

negative approach to urban growth planning of Beijing, China

China

Among other issues, the degrading environmental and ecological situations, the low performance scrambled city form and the loss of cultural identity in Beijing City have proved that the conventional ‘population projection-urban infrastructure-land use’ approach and the architectural urbanism approach to urban growth planning failed to meet the challenges of swift urbanisation and sustainability issues in China in general, and Beijing in particular.

Land-use change in the ‘edgelands’: Policies and pressures in London's rural–urban fringe

Journal Articles & Books

United Kingdom

Green Belt policies have helped to create chaotic landscapes at the rural–urban interfaces of the United Kingdom's largest cities. Their prime functions, to control urban sprawl and preserve an encircling green girdle to separate the urban from the open countryside, have created ‘edgelands’ that have been remarkably dynamic despite relatively strong controls on certain types of development.

Emergy-based evaluation of peri-urban ecosystem services

Journal Articles & Books
december, 2011
Global

Peri-urban areas are often characterized by valuable natural environments that provide essential life-support functions and ecosystem services for urban residents. Global environmental change has raised concerns over how urbanization and land use and land cover change affect ecosystem services. This study applied systems ecology theory and ecological energetic analysis to value the worth of natural environment and ecosystem services to a socioeconomic system. We begin with a general discussion of peri-urban areas and their ecosystem services.

Managing urban growth in a transforming China: Evidence from Beijing

China

Managing urban growth in the current rapid urbanization process has become a key issue for land use policy in transformation China. This paper maps and assesses the performance of urban containment strategies in China, looking at the case of Beijing over a 19-year period (1990–2009). The analysis shows that to a large extent containment strategies perform well in terms of concentrating urban growth in planned suburban areas and promoting compact development.

Future development of the Palestinian neighbourhoods in East Jerusalem: misuse of environmental concepts in land management

Journal Articles & Books
december, 2011

The urbanisation process in East Jerusalem has been described as a still process, in other words, a frozen or even rarely-developed process. This paper explores the Green and Open Landscape concept as one of the dominant factors described in the Jerusalem Master Plan. This factor is one that restrains urbanisation and hinders expansion of the Palestinian neighbourhoods in East Jerusalem. Both descriptive and comparative approaches were adopted to analyse and evaluate the historical development of green spaces and open landscape concepts in East Jerusalem.

Agricultural and green infrastructures: The role of non-urbanised areas for eco-sustainable planning in a metropolitan region

Italy

Non-Urbanised Areas (NUAs) are part of agricultural and green infrastructures that provide ecosystem services. Their role is fundamental for the minimization of urban pollution and adaptation to climate change. Like all natural ecosystems, NUAs are endangered by urban sprawl. The regulation of sprawl is a key issue for land-use planning. We propose a land use suitability strategy model to orient Land Uses of NUAs, based on integration of Land Cover Analysis (LCA) and Fragmentation Analysis (FA). With LCA the percentage of evapotranspiring surface is defined for each land use.

Exploring long-term land cover changes in an urban region of southern Europe

Italy
Europe

This paper addresses two important issues for large Mediterranean city regions: the differential impact of compact urban ‘growth’ and low-density ‘sprawl’ on land cover changes (LCCs), and their final effect on changing land cover relationships (LCRs). The urban expansion of Rome (Italy) during the last 50 years and the related LCCs were investigated as a paradigmatic example of compact versus dispersed urban development.

Mediterranean water resources in a global change scenario

Europe
Northern Africa

Mediterranean areas of both southern Europe and North Africa are subject to dramatic changes that will affect the sustainability, quantity, quality, and management of water resources. Most climate models forecast an increase in temperature and a decrease in precipitation at the end of the 21st century. This will enhance stress on natural forests and shrubs, and will result in more water consumption, evapotranspiration, and probably interception, which will affect the surface water balance and the partitioning of precipitation between evapotranspiration, runoff, and groundwater flow.

integrated approach to assessing multiple stressors for coastal Lake Superior

december, 2011

Biological indicators can be used both to estimate ecological condition and to suggest plausible causes of ecosystem degradation across the U.S. Great Lakes coastal region. Here we use data on breeding bird, diatom, fish, invertebrate, and wetland plant communities to develop robust indicators of ecological condition of the U.S. Lake Superior coastal zone. Sites were selected as part of a larger, stratified random design for the entire U.S. Great Lakes coastal region, covering gradients of anthropogenic stress defined by over 200 stressor variables (e.g.
