Reconstruction of contested landscape: Detecting land cover transformation hosting cultural heritage sites from Central India using remote sensing

Journal Articles & Books
Décembre, 2013
Inde

Central India hosts one of the largest repositories of archaeological sites in the world having a semi-arid climate and distinct eco-geography which is prone to rapid change due to human activities. This paper discusses the changes in land use and land cover for the past twenty-three years in the region altering the rich cultural heritage, revealing by the presence of numerous painted rock-shelter sites in the region. The land cover and land use changes in terms of deforestation, urban growth and development and sandstone mining have been evaluated in the present study.

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
Décembre, 2011
Chine

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.

Urbanization effects on leaf litter decomposition, foliar nutrient dynamics and aboveground net primary productivity in the subtropics

Journal Articles & Books
Décembre, 2015

Urbanization can alter nutrient cycling. This research evaluated how urbanization affected nutrient dynamics in the subtropics. We established 17–0.04 ha plots in five different land cover types—slash pine (Pinus elliottii) plantations (n = 3), rural natural pine forests (n = 3), rural natural oak forests (n = 4), urban pine forests (n = 3) and urban oak forests (n = 4) in the Florida panhandle, a subtropical region that has experienced rapid urbanization.

Planning and management modeling for treated wastewater usage

Journal Articles & Books
Décembre, 2009

Due to urban growth, some agricultural lands have been replaced by residential, municipal, and industrial areas. In some cases the remaining agricultural land will not have enough water because of transfers from agriculture to M''I (municipal and industrial) users. Therefore, in many places, especially in arid and semi-arid regions, the use of treated wastewater as a reliable source of irrigation water has already been, or will be, considered in the future.

spatial dimension of urban greenhouse gas emissions: analyzing the influence of spatial structures and LULC patterns in European cities

Journal Articles & Books
Décembre, 2015

CONTEXT: Integrative mitigation and adaptation strategies are needed to counter climate change. Indicators can be valuable that focus on the specific relevance of cities’ socioeconomic and spatial properties. While previous analyses have identified socioeconomic influences on urban greenhouse gas emissions, information about the role of spatial urban structures and land use and land cover patterns is sparse. OBJECTIVE: This study advances the use of spatial metrics for analyzing the linkages between the spatial properties of a city and its greenhouse gas emissions.

Land fragmentation and variation of ecosystem services in the context of rapid urbanization: the case of Taizhou city, China

Journal Articles & Books
Décembre, 2014
Chine

This study analyzes land use dynamics, land fragmentation, variation of ecosystem service value (ESV), and the underlying driving forces in the context of rapid urbanization in Taizhou city, China. An integrated approach utilizing geographic information system and remote sensing was used to analyze land use/land cover change, spatiotemporal patterns of land fragmentation and variation of ESV over the period of 1995–2010.

Raptor Presence Along an Urban–Wildland Gradient: Influences of Prey Abundance and Land Cover

Journal Articles & Books
Décembre, 2014

Native animals are affected differently by urbanization. Some species respond favorably and thrive in human-dominated landscapes, but others are extirpated. Raptors are often sensitive to changes in land cover and prey abundance. We therefore used a combination of broadcast surveys and incidental observations while spot-mapping to evaluate the influences of these two variables on the presence of raptors at 21 sites from 2004–2008 along an urban-to-wildland gradient in western Washington, U.S.A.

Examining the occurrence of mammal species in natural areas within a rapidly urbanizing region of Texas, USA

Journal Articles & Books
Décembre, 2016
États-Unis d'Amérique

In much of the United States and elsewhere, urbanization continues to transform landscapes. In central Texas, anthropogenic conversion of land is due in part to a rapidly growing population in the Austin and San Antonio metro areas and the subsequent infrastructure and resources needed to support that growth. Protected natural areas adjacent to urbanized landscapes are often intended to mitigate the impact of land development by serving as wildlife habitat.

Driving mechanism and boundary control of urban sprawl

Journal Articles & Books
Décembre, 2015
Chine

Since the reform and opening-up, China’s economy has achieved remarkable development and so does the urbanization. However, there is an unavoidable contradiction between urban sprawl and the protection of arable land and the environment. By redefining the urban sprawl boundary, this paper is to provide a solution for the conflict above on the China’s urbanization context. The ideal boundary, moderate boundary and limit boundary are defined for urban sprawl in space.

Soil erosion and sediment fluxes analysis: a watershed study of the Ni Reservoir, Spotsylvania County, VA, USA

Journal Articles & Books
Décembre, 2014
États-Unis d'Amérique

Anthropogenic forces that alter the physical landscape are known to cause significant soil erosion, which has negative impact on surface water bodies, such as rivers, lakes/reservoirs, and coastal zones, and thus sediment control has become one of the central aspects of catchment management planning. The revised universal soil loss equation empirical model, erosion pins, and isotopic sediment core analyses were used to evaluate watershed erosion, stream bank erosion, and reservoir sediment accumulation rates for Ni Reservoir, in central Virginia.

Environmental factors influencing the occurrence of coyotes and conflicts in urban areas

Journal Articles & Books
Décembre, 2016
États-Unis d'Amérique

The increase of global urbanization can have effects on wildlife species, including carnivores such as coyotes (Canis latrans). As coyotes continue to settle in more urban areas, reports of human-coyote conflicts, such as attacks on humans or pets, may also increase. Understanding environmental variables that might influence whether or not coyotes and human-coyote conflicts will occur in certain urban areas may assist wildlife officials in creating management plans for urban wildlife.
