Estimation of variables explaining urbanization concomitant with land-use change: a spatial approach

Journal Articles & Books
Dezembro, 2013
Índia

Urbanization in India is rapidly increasing. Dispersed development along highways or surrounding cities and in rural areas is resulting in serious loss of agricultural land, open space, waterbodies, and ecologically sensitive habitats. The management and monitoring of such resources require an understanding of change in land use and land cover. Vadodara City in Gujarat, India, has been chosen as the study area because it is a rapidly developing city with increasing urbanization and industrialization.

Towards an energy–landscape integrated analysis? Exploring the links between socio-metabolic disturbance and landscape ecology performance (Mallorca, Spain, 1956–2011)

Journal Articles & Books
Dezembro, 2016
Espanha

CONTEXT: The role of agricultural landscapes in biodiversity conservation is an emerging topic in a world experiencing a worrying decrease of species richness. Farm systems may either decrease or increase biological diversity, depending on land-use intensities and management. OBJECTIVES: We present an intermediate disturbance-complexity model (IDC) of cultural landscapes aimed at assessing how different levels of anthropogenic disturbance on ecosystems affect the capacity to host biodiversity depending on the land matrix heterogeneity.

soil moisture assimilation scheme based on the microwave Land Emissivity Model and the Community Land Model

Journal Articles & Books
Dezembro, 2012

Applications of microwave remote-sensing data in land data assimilation are a topic of current interest and importance due to their high temporal and spatial resolution and availability. However, there have been few studies on land surface sub-grid scale heterogeneity and calculating microwave wetland surface emissivity when directly assimilating gridded Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E) satellite brightness temperature (BT) data to estimate soil moisture.

Validation of MODIS, MISR, OMI, and CALIPSO aerosol optical thickness using ground-based sunphotometers in Hong Kong

Hong Kong

Aerosol observations are essential for understanding the Earth's radiation budget and the complexities of climate change, as they are involved in the backscattering of solar radiation and the formation of cloud condensation nuclei. In Hong Kong, the most direct effect is on air quality. Atmospheric haze caused by the emission of aerosols from industrial and vehicular sources creates visibility lower than 8 km for approximately 20% of the time, having risen at 6% per decade since 1980, but regional emissions are at least as influential as local ones.

Policy impacts on regulating ecosystem services: looking at the implications of 60 years of landscape change on soil erosion prevention in a Mediterranean silvo-pastoral system

Journal Articles & Books
Dezembro, 2016
Portugal

CONTEXT: Policy decisions form a major driver of land use change, with important implications for socially and environmentally susceptible regions. It is well known that there can be major unintended consequences, especially where policies are not tailored to regionally specific contexts. OBJECTIVES: In this paper we assess the implications of 60 years of agricultural policies on soil erosion prevention (SEP) by vegetation, an essential regulating ecosystem service in Mediterranean Europe.

integration of plant phenology and land use data to create a GIS-assisted bioclimatic characterisation of Bavaria, Germany

Journal Articles & Books

Alemanha

Background: Since phenology is a good bio-indicator of temperature the latter is often used in phenological analyses. However, whilst meteorological data are difficult to interpolate from point measurements at the desired resolution, region-wide digital data, e.g.

Assessment of forest disturbances by selective logging and forest fires in the Brazilian Amazon using Landsat data

Journal Articles & Books
Dezembro, 2013

The rapid environmental changes occurring in the Brazilian Amazon due to widespread deforestation have attracted the attention of the scientific community for several decades. A topic of particular interest involves the assessment of the combined impacts of selective logging and forest fires. Forest disturbances by selective logging and forest fires may vary in scale, from local to global changes, mostly related to the increase of carbon dioxide released into the atmosphere.

Grain for Green Project induced land cover change in the Loess Plateau: A case study with Ansai County, Shanxi Province, China

Journal Articles & Books
Dezembro, 2012
China

The Grain for Green Project (GGP) is the largest land retirement/afforestation program in China; it was primarily initiated to reduce the soil erosion and improve the ecological conditions in the Loess Plateau in 1999. If effective, this massive regional effort will induce significant improvement in the vegetation conditions. At this time, the effectiveness of the GGP has not been well documented.

Influence of land use/land cover (LULC) changes on atmospheric dynamics over the arid region of Rajasthan state, India

Journal Articles & Books
Dezembro, 2013
Índia

The present study examines the long-term effects of land use/land cover (LULC) changes in Rajasthan state, India on land-atmosphere fluxes and, possibly in precipitation and aerosol loading. By comparing the satellite observations from Landsat MSS (1972–73) and IRS-P6 AWiFS (2006–07) considerable LULC changes are observed, an increase in crop-land and vegetated areas of ∼57% in the eastern and ∼68% in the western Rajasthan.

Spatial Patterns of Breeding Success of Grizzly Bears Derived from Hierarchical Multistate Models

Journal Articles & Books
Dezembro, 2014
Canadá

Conservation programs often manage populations indirectly through the landscapes in which they live. Empirically, linking reproductive success with landscape structure and anthropogenic change is a first step in understanding and managing the spatial mechanisms that affect reproduction, but this link is not sufficiently informed by data. Hierarchical multistate occupancy models can forge these links by estimating spatial patterns of reproductive success across landscapes.

Assessing the impacts of watershed indexes and precipitation on spatial in-stream E. coli concentrations

Journal Articles & Books
Dezembro, 2012
Estados Unidos

Pathogen contamination of waterbodies, which is often identified by the presence of pathogen indicators such as Escherichia coli, is a major water quality concern in the United States. Reducing in-stream pathogen contamination requires an understanding of the combined impacts of land cover, climatic conditions, and anthropogenic activities at the watershed scale. In this study these factors are considered by assessing linear relationships between in-stream E. coli water quality data, watershed indexes, and rainfall for the Squaw Creek Watershed, IA, USA.

Temporal stability of vegetation indicators of wetland condition

Journal Articles & Books
Dezembro, 2013

Vegetation indices are widely employed to evaluate wetland ecological condition, and are expected to provide sensitive and specific detection of environmental change. Most studies evaluate the performance of condition assessment metrics in the context of the data used to calibrate them. Here we examined the temporal stability of the Florida Wetland Condition Index (FWCI) for vegetation of depressional forested wetlands by resampling sites in 2008 that were previously sampled to develop the FWCI in 2001.
