Modeling Future Urban Sprawl and Landscape Change in the Laguna de Bay Area, Philippines

Peer-reviewed publication
Juin, 2017

This study uses a spatially-explicit land-use/land-cover (LULC) modeling approach to model and map the future (2016–2030) LULC of the area surrounding the Laguna de Bay of Philippines under three different scenarios: ‘business-as-usual’, ‘compact development’, and ‘high sprawl’ scenarios. The Laguna de Bay is the largest lake in the Philippines and an important natural resource for the population in/around Metro Manila.

Spatial and Temporal Characteristics of Road Networks and Urban Expansion

Peer-reviewed publication
Juin, 2017

Urban expansion has become a widespread trend in developing countries. Road networks are an extremely important factor driving the expansion of urban land and require further study. To investigate the relationship between road networks and urban expansion, we selected Beijing, New York, London, and Chicago as study areas. First, we obtained urban land use vector data through image interpretation using a remote sensing (RS) and geographic information systems (GIS) platform and then used overlay analysis to extract information on urban expansion.

Development of Future Land Cover Change Scenarios in the Metropolitan Fringe, Oregon, U.S., with Stakeholder Involvement

Peer-reviewed publication
Mars, 2014

We describe a future land cover scenario construction process developed under consultation with a group of stakeholders from our study area. We developed a simple geographic information system (GIS) method to modify a land cover dataset and then used qualitative data extracted from the stakeholder storyline to modify it. These identified variables related to our study area’s land use regulation system as the major driver in the placement of new urban growth on the landscape; and the accommodation of new population as the determinant of its growth rate.

Spatiotemporal Patterns and Socioeconomic Contexts of Vegetative Cover in Altamira City, Brazil

Peer-reviewed publication
Décembre, 2013
Brésil

Ecosystem services provided by urban vegetation can ameliorate problems common to urban environments while improving the quality of life of urban residents. Much research in urban ecology has analyzed urban environmental dynamics in the global north; rapidly urbanizing areas in the global south have not received commensurate attention. The land cover dynamics of mid-sized cities in the global south remain under-explored in particular.

Perspectives of Livestock Farmers in an Urbanized Environment

Peer-reviewed publication
Mars, 2014
Espagne

Agriculture and its conflicts is a traditional debate in contemporary rural geography, associated with the organization and transformation of cultural landscapes by social groups. One of the most important areas of research is the perspectives and responses of farmers on the urban-rural fringe. The problems associated with land use change and the varying influences on new uses of traditional landscape introduce renovating and permanent elements to the management, responses and perspectives of farmers: extensification, changes in the organization of farm, relocation, etc.

Urbanity and Urbanization: An Interdisciplinary Review Combining Cultural and Physical Approaches

This review paper focuses on research schemes regarding urbanity and urbanization, and brings together both cultural and physical approaches. First, we review the cultural and social construction of urbanity (as related to urbanization) in Germany. In the early 20th century, urbanity was mainly the result of identity derived from a historical perspective in cities.

Built-up Area Change Analysis in Hanoi Using Support Vector Machine Classification of Landsat Multi-Temporal Image Stacks and Population Data

Peer-reviewed publication
Décembre, 2015

In 1986, the Government of Vietnam implemented free market reforms known as Doi Moi (renovation) that provided private ownership of farms and companies, and encouraged deregulation and foreign investment. Since then, the economy of Vietnam has achieved rapid growth in agricultural and industrial production, construction and housing, and exports and foreign investments, each of which have resulted in momentous landscape transformations. One of the most evident changes is urbanization and an accompanying loss of agricultural lands and open spaces.

Patterns of Wastewater Infrastructure along a Gradient of Coastal Urbanization: A Study of the Puget Sound Region

Peer-reviewed publication
Décembre, 2015

The aim of this paper is to explore patterns of wastewater infrastructures (sewers vs. septic tanks) in urbanizing watersheds across a coastal metropolitan region. This research combines an urban-rural gradient with spatial metrics at the patch and watershed scale (proportion of parcels on a treatment system, septic density, lot size and percent imperviousness) to analyze wastewater patterns in the Puget Sound, WA, USA. Results show that most urban residential parcels are hooked up to a sewer, although there remain urban residences on a septic tank with small lots.

Growing City and Rapid Land Use Transition: Assessing Multiple Hazards and Risks in the Pokhara Valley, Nepal

Peer-reviewed publication
Décembre, 2015
Népal

Pokhara is one of the most naturally beautiful cities in the world with a unique geological setting. This important tourist city is under intense pressure from rapid urbanization and population growth. Multiple hazards and risks are rapidly increasing in Pokhara due to unsustainable land use practices, particularly the increase in built-up areas. This study examines the relationship among urbanization, land use/land cover dynamics and multiple hazard and risk analysis of the Pokhara valley from 1990 to 2013.

The Linkages between Real Estate Tourism and Urban Sprawl in Majorca (Balearic Islands, Spain)

Peer-reviewed publication
Juin, 2013

Financial capitalism has driven profound changes in urban land use patterns in Majorca, at the Balearic Islands (Spain). This archipelago is a major tourist destination located in the Mediterranean basin, with 4,492 km2 of surface area, 1,113,114 inhabitants and 12,316,399 tourists (2011), of whom 29.9% came from Germany, 24% from the UK and 19% from the rest of Spain. Neoliberal state regulation has favored the elite’s financial interests in the real estate sector through transport megaproject investment and lifting regional planning restrictions which prevented urban growth.

Mapping Urbanization Dynamics in Major Cities of Colombia, Ecuador, Perú, and Bolivia Using Night-Time Satellite Imagery

By 2050, 90% of the population in Latin America will live in cities, but there is a lack of up-to-date spatial information about the urban extent and patterns of urbanization in cities of this region. In this study, we analyzed population growth, urban density and urbanization dynamics between 1992 and 2009 in the major cities of Bolivia, Colombia, Ecuador and Perú using Google Earth and DMSP/OLS night-time lights imagery. We used Google Earth to map the urban extent, and time series of night-time lights to analyze spatial patterns of urban development.

Rural-Urban Transition in Central Java: Population and Economic Structural Changes Based on Cluster Analysis

Peer-reviewed publication
Septembre, 2013

In Central Java, in addition to the traditional view of urban transition as an aspect of urban industrialization, rural industrialization based on small- to medium-sized enterprises has become a concern, at least since the Indonesian economic crisis in 1997. Combinations of typical urban and rural activities have resulted in certain features of rural-urban transition as the urban population has continued to increase notably. The intention of this paper is to examine how rural-urban transition characterizes the industrialization of Central Java.
