Impact of loess relief on land use mosaic in SE Poland

Journal Articles & Books
Dezembro, 2012

Land cover is one of the most changeable environment components in time and space. The type, intensity and spatial distribution of land use forms result directly from the actual and former character of agriculture. In this study, an attempt was made to assess the impact of loess relief on the spatial diversity of land use patch features. The research was carried out within three test areas covering a total of about 100km². The test areas are located within the loess areas of SE Poland. Spatial analyses were carried out using GIS software.

Climate, human palaeoecology and the use of fuel in Wadi Sana, Southern Yemen

Journal Articles & Books
Dezembro, 2014
Iémen

This study integrates analysis of wood charcoal assemblages with climate proxies, palaeoenvironmental and archaeological data sets in hyper-arid Wadi Sana, Yemen, to address the availability and use of wood fuels by South Arabian hunter-herder groups from the Early Holocene (8000–7700� cal. B.P.) to Middle Holocene (6900–4800� cal. B.P.) periods.

Deforestation dynamics and policy changes in Bolivia's post-neoliberal era

Journal Articles & Books
Dezembro, 2011
Bolívia

This work compares the effects of neoliberal and post-neoliberal land-use policies on forest cover along the Corredor Bioceánico of southeastern Bolivia to determine if rates of agriculturally driven forest clearance have changed since the Morales’ administration came to office in 2005. Satellite image analysis, supported by semi-structured interviews with farmers and representatives of key institutions, shows that deforestation for commercial agriculture in Santa Cruz continues and has increased in certain “hotspots”.

Can tropical farmers reconcile subsistence needs with forest conservation?

Journal Articles & Books
Dezembro, 2009
Equador

If tropical farmers cannot be provided with sustainable land‐use systems, which address their subsistence needs and keep them gainfully employed, tropical forests will continue to disappear. We looked at the ability of economic land‐use diversification – with reforestation of tropical “wastelands” as a key activity – to halt deforestation at the farm level.

Effects of spatial resolution of remotely sensed data on estimating urban impervious surfaces

Journal Articles & Books
Dezembro, 2011
China

Impervious surfaces are the result of urbanization that can be explicitly quantified, managed and controlled at each stage of land development. It is a very useful environmental indicator that can be used to measure the impacts of urbanization on surface runoif, water quality, air quality, biodiversity and microclimate. Therefore, accurate estimation of impervious surfaces is critical for urban environmental monitoring, land management, decision-making and urban planning.

On the distance travelled for woodland leisure via different transport modes in Wallonia, south Belgium

Journal Articles & Books
Dezembro, 2016
Bélgica

Based on an extensive survey of woodland visitors in Wallonia, south Belgium, we examined a wide range of individual-, residential- and destination-level variables for their associations with the distance travelled for woodland leisure on foot, by bicycle and by car. For each transport mode, explanatory bivariate analyses were conducted firstly to identify potential correlates of the distances travelled. Then, cross-classified multilevel analysis was performed to build estimation models for the trip distance.

Future Potential for Forestry Cooperatives - Results from an Institutional Economic Approach

Conference Papers & Reports
Dezembro, 2011

In dem vorliegenden Beitrag werden am Beispiel des Landes Hessen die Entwicklungsperspektiven von Forstbetriebsgemeinschaften aufgezeigt. Die strukturelle Bedeutung derartigerZusammenschlüsse für die hessische Forstwirtschaft ist auch daraus ersichtlich, dass gegenwärtig etwa die Hälfte der hessischen Waldfläche auf forstwirtschaftliche Zusammenschlüsseentfällt. In einem ersten Untersuchungsschritt werden anhand von theoretischen Überlegungen aus der Institutionenökonomie Optionen für die zukünftige Ausrichtung der Forstbetriebsgemeinschaftenbeleuchtet.

Ecological restoration planning based on connectivity in an urban area

Journal Articles & Books
Dezembro, 2012

In urban areas, the competition between land development and ecological conservation is intense. To mitigate the negative effects of urbanization, we developed a methodology to plan a spatially explicit conservation network based on widely available remotely sensed data and other auxiliary data. First, as an area of strategic significance for the conservation of regional flora and fauna and for maintaining high environmental quality to promote human well-being, the remaining natural and semi-natural areas were identified as ecologically primary areas.

THE MEDIATION OF VARIANCE CONFLICTS: AN EMPIRICAL EVALUATION

Policy Papers & Briefs
Dezembro, 2000

Since 1982, the New Castle County Superior Court in Delaware has promoted mediation, which attempts to resolve filed conflicts prior to trial. This paper evaluates how spatial land-use conflicts channel through mediation and litigation. Data suggest that mediations fail because one of the key disputing parties does not play a direct role in mediation and litigation. The data then inform a predictive model of litigated outcomes in which disputants share in the responsibility for conflict.

Spatio-temporal variability of streamflow in the Yellow River: possible causes and implications

Journal Articles & Books
Dezembro, 2012
China

The water shortage in the Yellow River, China, has been aggravated by rapid population growth and global climate changes. To identify the characteristics of streamflow change in the Yellow River, approximately 50 years of natural and observed streamflow data from 23 hydrological stations were examined. The Mann-Kendall and Pettitt tests were used to detect trends and abrupt change points.

Structural Agricultural Land Use Modelling

Conference Papers & Reports
Dezembro, 2009

This paper develops a structural econometric model of agricultural land use and production based on the joint multi-output technology representation introduced by Chambers and Just (1989). Starting from a flexible specification of the farm profit function we derive land use allocation, inputapplications, crops yield and livestock number equations in a joint and theoretically consistent framework.
