evolution of the timber sector in lowland Bolivia: Examining the influence of three disparate policy approaches

Journal Articles & Books
Dezembro, 2010
Bolívia

This paper assesses the influence of forest policies on forestry development, and especially timber production, in Bolivia during three different periods of time. The first period began in the early 1970s when a conservative forest policy was adopted privileging commercial logging companies, and thus fueling land conflicts in particular with indigenous people, allowing a minority to accumulate considerable wealth, and marking the onset of forest degradation.

SPATIAL DEVELOPMENTS OF HUNGARIAN AGRICULTURE IN THE TRANSITION: THE CASE OF CROP PRODUCTION

Policy Papers & Briefs
Dezembro, 2007
Hungria

The paper investigates spatial changes in cultivation and land use of wheat, maize and oilseedin Hungarian agriculture using different methods to measure these changes. The results suggestthat spatial structure of crop productions has remained fairly stable during analysed period. Thespatial concentration increased significantly for wheat and maize production and maize landuse, whilst the changes were not significant for other cases. Estimates confirm the presence ofspatial autocorrelation for all cases.

Geo-Wiki: An online platform for improving global land cover

Journal Articles & Books
Dezembro, 2012

Land cover derived from remotely sensed products is an important input to a number of different global, regional and national scale applications including resource assessments and economic land use models. During the last decade three global land cover datasets have been created, i.e. the GLC-2000, MODIS and GlobCover, but comparison studies have shown that there are large spatial discrepancies between these three products. One of the reasons for these discrepancies is the lack of sufficient in-situ data for the development of these products.

Delineation of Groundwater Recharge Potential Zones in Namakkal District, Tamilnadu, India Using Remote Sensing and GIS

Journal Articles & Books
Dezembro, 2015
Índia

Exploitation of groundwater and frequent failure of monsoons has produced rapid water table depletion in present days. Rainwater is discharged as surface runoff without replenishing the groundwater table. Identification of potential zones for groundwater recharge has become an important event to replenish the groundwater resources. The recharge potential is governed by various features of surface, subsurface and hydrometeorological parameters. Remote sensing technique is found to be very effective tool for the integration of various features of these factors.

Role of state administration in updating land-estate and farm-size conditions

Conference Papers & Reports
Dezembro, 2007

The structure of land estates and farm-sizes are the basis of a competitive agricultural production, hence these questions belong to the evergreen themes both of theory and practice also on international level. In Central and Eastern European Countries (CEECs), the change ofpolitical and economic regime virtually tore into the agriculture in beginning of 1990s, destroying the existing structure of land estates by the privatization, restitutions or restoration of ownership rights resulting in fragmentation of land ownership.

Using a groundwater quality negotiation support system to change land-use management near a drinking-water abstraction in the Netherlands

Journal Articles & Books
Dezembro, 2008
Países Baixos

A negotiation support system (NSS) was developed to solve groundwater conflicts that arose during land-use management. It was set up in cooperation with the stakeholders involved to provide information on the impact of land use, e.g., agriculture, nature (forested areas), recreation, and urban areas, on the quality of both infiltrating and abstracted groundwater. This NSS combined simulation programs that calculate (1) the concentrations of nitrate in shallow groundwater for each land-use area and (2) the transport of nitrate in the groundwater-saturated zone.

Assessing the benefits and costs of dryland forest restoration in central Chile

Journal Articles & Books
Dezembro, 2012
Chile

Investment in natural capital restoration is increasing as a response to the widespread ecological degradation of dryland forests. However, finding efficient mechanisms to promote restoration among private landowners is a significant challenge for policy makers with limited financial resources. Furthermore, few attempts have been made to evaluate the costs and benefits of restoration interventions even though this information is relevant to orient decision making.

Habitat selection in a changing environment: the relationship between habitat alteration and Scops Owl (Aves: Strigidae) territory occupancy

Journal Articles & Books
Dezembro, 2013
Itália

The Scops Owl Otus scops (L., 1758) is a species of European concern, which suffered a noticeable decrease in distribution in the last decades, and changes in agricultural practices have been proposed as a major threat for this owl. We studied the habitat preference of the Scops Owl by assessing the habitat occupancy of 401 territories distributed in a large area in northwest Italy, with a special focus on 98 territories located in a high-density area (Monferrato).

Assessing the effects of land use and land cover patterns on thermal conditions using landscape metrics in city of Indianapolis, United States

Journal Articles & Books
Dezembro, 2007
Estados Unidos

Direct applications of remote sensing thermal infrared (TIR) data in landscape ecological research are rare due to limitations in the sensors, calibration, and difficulty in interpretation. Currently there is a general lack of methodology for examining the relationship between land surface temperatures (LST) derived from TIR data and landscape patterns extracted from optical sensors. A separation of landscapes into values directly related to their scale and signature is a key step.

Koala and Possum Populations in Queensland during the Harvest Period, 1906-1936

Journal Articles & Books
Dezembro, 2005

The Queensland Koala Phascolarctos cinereus and possum harvests were regulated from 1906-1927 and 1906-1936, respectively. Before that, there was an uncontrolled harvest. Historical data from the harvest period were analysed to gain information on P. cinereus and possum (mainly Trichosurus vulpecula) population ecology and status. P. cinereusi> numbers peaked in southern Queensland around the turn of the century or in the first decade of the 20th century.

Past land use decisions and socioeconomic factors influence urban greenbelt development: a case study of Shanghai, China

Journal Articles & Books
Dezembro, 2014
China

Although the designation of greenbelts around cities has been a common practice for several decades, some greenbelts have not been successfully protected from development. To explore the forces driving the construction of greenbelts, this paper examines how past land use and land cover decisions and current socioeconomic factors have affected the development of the artificial greenbelt zone in China’s Shanghai metropolitan area. Using aerial photographs from 1994, 2005, and 2010, we find that the area of afforested greenbelt was generally related to past land use/cover decisions.
