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).

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.

impacts of global change in the humid tropics: selected rainfall-runoff issues linked with tropical forest-land management

Journal Articles & Books

Austrália
América Central

Within the framework of IWRM, a major concern in the humid tropics is the effects of ‘global warming' on the storm rainfall-runoff hydrology of both forests and converted forest lands. Further how such effects need to be incorporated within adaptive, forest-water-land management. But since the mid- 20th century, dramatic changes in land- use (LU) and land cover (LC) have also occurred which have led to rapid rates of deforestation and an expansion of land--forest degradation.

Optical and radar data integration for land use and land cover mapping in the Brazilian Amazon

Journal Articles & Books
Dezembro, 2013

This study aims to evaluate different methods of integrating optical and multipolarized radar data for land use and land cover (LULC) mapping in an agricultural frontier region in the Central Brazilian Amazon, which requires continuous monitoring due to the increasing human intervention. The evaluation is performed using different sets of fused and combined data.

integrated GIS-based interval-probabilistic programming model for land-use planning management under uncertainty—a case study at Suzhou, China

Journal Articles & Books
Dezembro, 2015
China

A large number of mathematical models have been developed for supporting optimization of land-use allocation; however, few of them simultaneously consider land suitability (e.g., physical features and spatial information) and various uncertainties existing in many factors (e.g., land availabilities, land demands, land-use patterns, and ecological requirements). This paper incorporates geographic information system (GIS) technology into interval-probabilistic programming (IPP) for land-use planning management (IPP-LUPM).

Evaluating the use of publicly available remotely sensed land cover data for areal interpolation

Journal Articles & Books
Dezembro, 2013

Areal interpolation is used to transfer attribute data between geographically incongruous zonal systems. Remotely sensed land cover data are widely used in intelligent areal interpolation methods to solve this problem. This article examines the usefulness of different publicly available remotely sensed land cover data sets as ancillary data used in conjunction with different areal interpolation methods.

Differences in land cover interpretation in landscapes rich in cover gradients: reflections based on the montado of South Portugal

Journal Articles & Books
Dezembro, 2007
Portugal

This paper contributes to the discussion on current issues in methodologies of mapping land cover in the agro-silvo-pastoral landscapes of the Mediterranean. These landscapes, characterized by intermixed land use and indefinite boundaries, require particular attention in applying the patch-corridor-matrix model when classifying patches and their delineation. In a case study area in southeast Portugal, mainly characterized by agro-silvo pastoral systems, the land cover for 1990 has been mapped.

Integrating geo-information models with participatory approaches : applications in land use analysis

Journal Articles & Books
Dezembro, 2004
Índia

In this thesis we demonstrate some methods to integrate biophysical data with socio-economic variables with applications in agricultural land use analysis. Part of Nizamabad District of Andhra Pradesh State in India is considered for developing and testing the methods developed. First the study area is stratified as a pre-field work exercise for a focused land use analysis.

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

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.
