Potential distribution and population size of the Eurasian lynx Lynx lynx in the jura Mountains and possible corridors to adjacent ranges

Journal Articles & Books
Dezembro, 2007

To estimate the potential population size of the Eurasian lynx Lynx lynx in the Jura Mountains and to assess possible corridors between this population and adjacent areas (the Vosges Mountains, the Black Forest and the Alps), we adapted a previously developed Geographic Information system (GIS) probability model for lynx distribution and extrapolated it over the entire mountain range. The model was based on knowledge of the habitat use and land tenure system of resident animals from the central part of the Jura Mountains, where lynx were followed by means of radio-telemetry.

Determination of the land-uses in the close proximity of the River of Kura in Ardahan and optimal land use proposals

Policy Papers & Briefs
Dezembro, 2008

Today, natural and cultural reserves are being rapidly lost; however, no efficient protection approaches are being put forward. Existent reserves face with the danger of extinction as the result of the land-misuses and excessive utilisation. In order to make accurate and effective reserve management and planning decisions, optimal land-uses targeting the preservation ecological structure should be determined elaborately.

Role of Forest Income in Rural Household Livelihoods: The Case of Village Common Forest Communities in the Chittagong Hill Tracts, Bangladesh

Journal Articles & Books
Dezembro, 2015
Bangladesh

Forests play an important role in the livelihoods of ethnic communities living in the south-eastern region, the Chittagong Hill Tracts (CHTs), of Bangladesh. Over decades, deforestation and land degradation have markedly affected ethnic peoples’ livelihoods in the CHTs. Although communities once managed extensive forest commons to support their livelihood needs, population explosion triggered fragmentation of common land leading to a gradual decline in livelihood opportunities.

Land use determines interest in conservation easements among private landowners

Journal Articles & Books
Dezembro, 2013
Estados Unidos

Protection of private lands through conservation easements has garnered recent attention from scientists and conservation practitioners. Questions remain, however, about the specific characteristics and activities driving landowners’ interest in conservation easements and their willingness to consider granting them. Resolving these questions could improve prospects for private land conservation by helping land conservation organizations identify and better understand potential easement grantors.

responses of evapotranspiration due to changes of LUCC under seawater intrusion in a coastal region

Journal Articles & Books
Dezembro, 2013
China

The paper provides a coherent pattern identification analysis of the impacts of coastal land use and land cover (LULC) on evapotranspiration (ET) under the impact of seawater intrusion. The study applied the Landsat satellite data to characterize the LULC at Laizhou Bay, Shandong Province, China. Then, the ET and heat fluxes were estimated using the surface energy balance algorithm for land model with two-time phase thermal infrared band images and regional surface parameters.

Patterns and causes of land change: Empirical results and conceptual considerations derived from a case study in the Swabian Alb, Germany

Journal Articles & Books
Dezembro, 2013
Alemanha

Land-use and land-cover change profoundly affect human well-being and, therefore, have become a major topic for society. A thorough understanding of past and present processes transforming landscapes is essential for guiding future developments toward the sustained provision of the ecosystem services humans critically depend upon. Drawing on the driving forces and resilience frameworks, we identify possible variables and patterns of land change, connecting them to empirical findings in three case study areas in the Swabian Alb region, southwestern Germany.

Stability evaluation of the number of farmers farms and declared agricultural land in Lithuania

Conference Papers & Reports
Dezembro, 2016
Letónia
Lituânia

The beginning of the restitutional land reallocation reform in 1991 brought a rapid change in agricultural land utilisation and user groups resulting in the decrease of state land users’ categories and the growth of private agricultural land areas used by farmers and other natural and legal entities. The aim of the article is to analyse the stability of farmers farms and their agricultural areas in Lithuania during the period between 2009 and 2014.

Landscape characteristics affecting streams in urbanizing regions of the Delaware River Basin (New Jersey, New York, and Pennsylvania, U.S.)

Journal Articles & Books
Dezembro, 2010
Estados Unidos

Widespread and increasing urbanization has resulted in the need to assess, monitor, and understand its effects on stream water quality. Identifying relations between stream ecological condition and urban intensity indicators such as impervious surface provides important, but insufficient information to effectively address planning and management needs in such areas.

Ecological consequences of rapid urban expansion: Shanghai, China

Journal Articles & Books
Dezembro, 2006
China

Since China's economic reform in the late 1970s, Shanghai, the country's largest and most modern city, has experienced rapid expansion and urbanization. Here, we explore its land‐use and land‐cover changes, focusing on the impacts of the urbanization process on air and water quality, local climate, and biodiversity. Over the past 30 years, Shanghai's urban area and green land (eg urban parks, street trees, lawns) have increased dramatically, at the expense of cropland.

Employing lidar data to identify butterfly habitat characteristics of four contrasting butterfly species across a diverse landscape

Journal Articles & Books
Dezembro, 2013
Estados Unidos

Lidar and orthophotograph-derived land cover are combined with in situ vegetation measurements to assess habitat characteristics typifying four species of butterflies with differing habitat preferences across a large spatial extent (∼30,000 ha) in northern Idaho, USA. Lidar data are employed to characterize both vegetation structure and topography, whereas digital orthophotographs and in situ vegetation measurements are employed to quantify surrounding land use and larval host plant cover, respectively.

Multiple approaches to valuation of conservation design and low-impact development features in residential subdivisions

Journal Articles & Books
Dezembro, 2012

Residents, developers and civic officials are often faced with difficult decisions about appropriate land uses in and around metropolitan boundaries. Urban expansion brings with it the potential for negative environmental impacts, but there are alternatives, such as conservation subdivision design (CSD) or low-impact development (LID), which offer the possibility of mitigating some of these effects at the development site.

Multi-temporal assessment of land sensitivity to desertification in a fragile agro-ecosystem: Environmental indicators

Journal Articles & Books
Dezembro, 2012
Egito

Human activities as well as natural events can dramatically affect land degradation negatively or positively. In Egypt, agriculture is a key sector of the economy. Land reclamation seeks to transfer desert areas to agricultural land and support the construction of new villages. The agricultural productivity improvement of these Newlands is slow and requires considerable time due to their fragility and sensitivity to desertification.
