Environmental and land use determinants of grassland patch diversity in the western and eastern Alps under agro-pastoral abandonment

Journal Articles & Books
Dezembro, 2016

Agro-pastoral decline in European mountain areas has recently caused changes to traditional landscapes with negative consequences on semi-natural grassland conservation and the associated biodiversity and ecosystem services. In the Italian Alps, grassland patches enclosed in a forest matrix are progressively disappearing. Two alpine valleys (Pesio and Pejo), having similar land-use history, were chosen as representative of management conditions of western and eastern Italian Alps, respectively.

Hierarchical Community Occurrence Model for North Carolina Stream Fish

Estados Unidos
América do Norte

The southeastern USA is home to one of the richest—and most imperiled and threatened—freshwater fish assemblages in North America. For many of these rare and threatened species, conservation efforts are often limited by a lack of data. Drawing on a unique and extensive data set spanning over 20 years, we modeled occurrence probabilities of 126 stream fish species sampled throughout North Carolina, many of which occur more broadly in the southeastern USA.

Land Use/Cover Change Detection of Tiruchirapalli City, India, Using Integrated Remote Sensing and GIS Tools

Índia

The rapid growth of urban population in India is a cause of concern among country’s urban and town planners for efficient urban planning. The drastic growth of urban areas has resulted in sharp land use and land cover changes. In recent years, the significance of spatial data technologies, especially the application of remotely sensed data and geographical information systems (GIS) has been widely used. The present study investigates the urban growth of Tiruchirapalli city, Tamilnadu using IRS satellite data for the years 1989, 1992, 1995, 1998, 2001, 2004, 2007, and 2010.

Linking long-term gully and river channel dynamics to environmental change using repeat photography (Northern Ethiopia)

Journal Articles & Books
Dezembro, 2011

In the Highlands of Northern Ethiopia gully occurrence is linked to poverty-driven unsustainable use of the land in a vulnerable semi-arid and mountainous environment, where intensive rainfall challenges the physical integrity of the landscape. Trends in gully and river channel erosion, and their relation to triggering environmental changes can proffer valuable insights into sustainable development in Northern Ethiopia.

Macroinvertebrate assemblages of peatland lakes: Assessment of conservation value with respect to anthropogenic land-cover change

Journal Articles & Books
Dezembro, 2013
Europa

Small blanket bog lakes can contain many rare and threatened aquatic invertebrate species. Their conservation value, however, is threatened throughout Europe by peat extraction and particularly conifer afforestation, which can compromise the physico-chemical habitat quality of peatland lakes through excessive inputs of forestry-derived dissolved and particulate substances.

Land Cover Change Characteristics of North-South Transect in Northeast Asia from 2001 to 2012

Northeast Asia is an area with relative concentrations of resources, a complex ecological environment pattern, and a marked human—land contrast relationship. This area has significance for analyzing land cover patterns and variations for regional sustainable development among the trans-boundary areas of China, Russia, and Mongolia. In this paper, the transect analysis research tool and transfer matrix method are used to capture the regional land cover change characteristics by using Moderate Resolution Imaging Spectroradiometer(MODIS) datasets recorded from 2001 to 2012.

Overview of national inventories for the LULUCF sector

Conference Papers & Reports
Dezembro, 2011

Under the United Nations Framework Convention on Climate Change (UNFCCC), Annex I countries that are Parties to the Climate Change Convention provide annual greenhouse gas (GHG) inventory submissions including GHG data for the land use, land-use change, and forestry (LULUCF) sector. For many countries, carbon sequestration – especially in Forest Land-offsets a significant proportion of national emissions both an-nually and overtime.

regression tree-based method for integrating land-cover and land-use data collected at multiple scales

Journal Articles & Books
Dezembro, 2007

As data sets of multiple types and scales proliferate, it will be increasingly important to be able to flexibly combine them in ways that retain relevant information. A case in point is Amazonia, a large, data-poor region where most whole-basin data sets are limited to understanding land cover interpreted through a variety of remote sensing techniques and sensors. A growing body of work, however, indicates that the future state of much of Amazonia depends on the land use to which converted areas are put, but land use in the tropics is difficult to assess from remotely sensed data alone.

Towards long-multitemporal change detection using SVI differencing by integrated DWT–ISOCLUS: a model for forest temporal dynamics mapping

Journal Articles & Books
Dezembro, 2011
Quênia

Characterisation and mapping of land cover/land use within forest areas over long-multitemporal intervals is a complex task. This complexity is mainly due to the location and extent of such areas and, as a consequence, to the lack of full continuous cloud-free coverage of those large regions by one single remote sensing instrument. In order to provide improved long-multitemporal forest change detection using Landsat MSS and ETM + in part of Mt.

myth of encroachment

Nova Zelândia

Scholars of pastoralism often refer to changes of pastoral land tenure as ‘encroachment.’ The New Zealand case of pastoral land tenure reform suggests that this is incorrect for several reasons. First it takes the point of view of the pastoralist, which introduces unnecessary bias. Second, it assumes that all changes in land tenure are situations in which the state, or another powerful agent, takes land away from the less powerful pastoralists.
