Surface temperature and hydrochemistry as indicators of land cover functions

Journal Articles & Books
Décembre, 2012

This paper presents an integrated approach to landscape functioning assessment combining energy efficiency and hydrochemical balance studies. Energy balance is expressed by surface temperature while hydrochemical balance is illustrated by electric conductivity and selected hydrochemical parameters. Six model sub-watersheds with different land use situated in southern Bohemia were chosen to show the influence of landscape management on landscape functioning.

Badger (Taxidea taxus) Resource Selection and Spatial Ecology in Intensive Agricultural Landscapes

Journal Articles & Books
Décembre, 2014

American badgers (Taxidea taxus) are a prairie obligate species, but badger resource selection and space use is poorly understood, particularly east of the Mississippi River where anthropogenic land uses have replaced most native prairie. We assessed badger multi-scale resource selection and space use in intensive agricultural areas in Illinois and Ohio. We predicted that badgers would select for pasture and prairie, and higher elevations, and riparian areas because these habitats likely favor burrowing and foraging.

Influence of land use patterns on some limnological characteristics in the south-eastern part of Lake Victoria, Tanzania

Tanzania

To investigate the influence of human activities on limnological characteristics of Lake Victoria, we analyzed inorganic nutrient concentrations, phytoplankton diversity and biomass at three locations with different land use patterns: Mwanza (urban/industrial), Magu (agricultural) and Kayenze (sparsely populated). Mwanza had significantly higher ammonia concentration compared to Kayenze and Magu. At the shoreline stations, significantly higher nitrate concentration was observed at Mwanza compared to Kayenze and Magu.

Early succession arthropod community changes on experimental passion fruit plant patches along a land-use gradient in Ecuador

Many tropical landscapes are today characterized by small forest patches embedded in an agricultural mosaic matrix. In such highly fragmented landscapes, agroforests have already been recognized as refuges for biodiversity but few studies have investigated the potential of non-forested land-use types to contribute to overall biodiversity of functionally important taxa in the tropics.

Land cover mapping applications with MODIS: a literature review

Journal Articles & Books
Décembre, 2012

Land use/land cover monitoring and mapping is crucial to efficient management of the land and its resources. Since the late 1980s increased attention has been paid to the use of coarse resolution optical data. The Moderate Resolution Imaging Spectroradiometer (MODIS) has features, which make it particularly suitable to earth characterization purposes. MODIS has 10 products dedicated mainly to land cover characterization and provides three kinds of data: angular, spectral and temporal. MODIS data also includes information about the data quality through the ‘Quality Assessment’ product.

264 years of change and persistence in an agrarian landscape: a case study from the Swiss lowlands

Journal Articles & Books
Décembre, 2015
Europe

CONTEXT: Century-long interaction between societies and their environment has shaped the cultural landscapes across Europe. Specific farming systems have persisted for long periods, and their abandonment has led to far-reaching and rapid changes in patterns of land use and land cover. OBJECTIVE: Taking the example of the municipality of Limpach, located in the Swiss lowlands, we studied the dynamics of cultural landscape and related driving forces in a long-term perspective.

Agricultural land use suitability analysis using GIS and AHP technique

Turquie

The aim of this study was to determine suitable lands for agricultural use in the Yusufeli district of Artvin city (Turkey), where the current agricultural land in the district center and 3 villages will be completely inundated while the land in 22 villages will be partially inundated due to three large dams currently being constructed. The “Analytic Hierarchy Process (AHP)” method, commonly used in land use suitability analysis, was utilized in this study.

From Pasture Land to Farm Plots, Triggers and Motivations for Land Use Changes in Afar, Ethiopia

Éthiopie

Communal land use system has existed in pastoral Afar (as in many other pastoral areas) since time of immemorial accommodating the interests of different user groups. This form of land use system, which has adapted to the harsh environment in which herders raise their livestock, enables efficient utilization of scattered pastoral resources since it accommodates constant mobility of livestock. In contrast to the mobile way of life, which characterizes pastoralism, farming as a sedentary activity is only marginally present in the lowlands of the Afar region.

impact of land use and land cover change on net primary productivity on China’s Sanjiang Plain

Journal Articles & Books

Chine

Land use and land cover change (LUCC) have a significant influence on regional ecosystems and on the carbon cycle. The Sanjiang Plain is one of the largest grain production bases in China, and has experienced rapid land cover change, making it a critical area in which to assess the environmental impact of LUCC and propose strategies for minimizing its impact on net primary productivity (NPP). In this study, land cover was estimated from remote sensing images to quantify LUCC on the Sanjiang Plain from 2000 to 2010.

Multiple site tower flux and remote sensing comparisons of tropical forest dynamics in Monsoon Asia

Journal Articles & Books
Décembre, 2008

The spatial and temporal dynamics of tropical forest functioning are poorly understood, partly attributed to a weak seasonality and high tree species diversity at the landscape scale. Recent neotropical rainforest studies with local tower flux measurements have revealed strong seasonal carbon fluxes that follow the availability of sunlight in intact forests, while in areas of forest disturbance, carbon fluxes more closely tracked seasonal water availability.
