Land Use Consequences of Crop Insurance Subsidies

Policy Papers & Briefs
Décembre, 2011

There have long been concerns that federal crop insurance subsidies may significantly impact land use decisions. It is well known that classical insurance market information asymmetry problems can lead to a social excess of risky land entering crop production. Our conceptual model shows that the problem will arise absent any information failures. This is because the subsidy is i) proportional to acres planted, and ii) greatest for the most production risky land.

Differential influence of land use/cover change on topsoil carbon and microbial activity in low-latitude temperate forests

Mexique

Land use/cover change (LUCC) is one of the main factors that control the terrestrial carbon (C) cycle. We examined the effect of LUCC on topsoil C, microbial biomass C (MBC) and microbes mediated processes related to C circulation and their relationship with other soil properties in low-latitude mountain temperate forests. We selected three sites in the northwest of Cofre de Perote volcano (Mexico) in an altitudinal gradient (piedmont, lower mountain slope and mid slope).

Detection and analysis of land-use and land-cover changes in the Midwest escarpment of the Ethiopian Rift Valley

Journal Articles & Books
Décembre, 2012

This study detects patterns of land-use and land-cover changes in the last three decades (1972–2004) and analyses its causative factors in the Upper Dijo River catchment, Midwest escarpment of Ethiopian Rift Valley. Data captured through the synergy of an aerial photo, satellite image and ground-based socio-economic survey were analysed by GIS and SPSS. The results showed a decline in shrub-grassland and riverine trees at 21.5 and 16.3 ha per year, respectively, and increase in plantation trees, annual crops and bare/open grasslands at 2.8, 12.5 and 24.8 ha per year, respectively.

Estimating urban vegetation cover fraction using Google Earth® images

États-Unis d'Amérique

We exploited publicly available satellite- and aircraft-based imagery to estimate urban vegetation cover fraction and land use by class for a semiarid urban area that includes Phoenix, AZ, USA, using low-cost and technologically modest tools. This technique is also used to evaluate two satellite-derived tree cover datasets as well as to compare estimates from the present study with land cover data generated from another study performed using the same study domain.

Ecological-economic zoning of the territory of the Republic of Belarus for the purposes of land use planning

Policy Papers & Briefs

Bélarus

The article presents ecological and economic zoning of the territory of the Republic of Belarus for the purposes of land use planning by the method of average differences, taking into account the factors which influence the efficiency of agricultural lands usage.

Reasons for introducing 3D property in a legal system—Illustrated by the Swedish case

Journal Articles & Books
Décembre, 2013

The use of three-dimensional (3D) property rights has for many years been a tool for providing secure and lasting rights for the use of land and its volume of space in complex situations involving land use in the urban society. The aim of this article is to investigate the reasons for introducing 3D property in a legal system. This is illustrated by using the Swedish system as an example. In general, without the possibility of forming 3D property units with direct ownership, other forms have to be used, such as indirect ownership or granted user rights.

Motivations and Land-Use Intentions of Nonindustrial Private Forest Landowners: Comparing Inheritors to Noninheritors

Journal Articles & Books
Décembre, 2009

The documented importance of intergenerational human capital transfers in agriculture generally gives us reason to suspect that such transfers may be important in a forestry context and that there may be important implied differences between first-generation woodland owners and multigeneration woodland owners with respect to their motivations and future intentions.

Evaluation of Ecosystem Services related to Bio-Energy Landscape Connectivity (BELC) for land use decision making across different planning scales

Journal Articles & Books
Décembre, 2016

Landscape connectivity is of paramount importance not only in maintaining both functionality and resilience of social-ecological systems, but also in providing Ecosystem Services (ESs). Despite recent efforts, several issues still need to be faced to fully integrate ESs evaluation relating to landscape connectivity into effective plans and environmental assessment procedures. Choosing an appropriate scale of analysis is one of the most problematic topics, since it can profoundly affect the evaluation of single patch contribution to global connectivity.

assessment of the effectiveness of a rotation forest ensemble for land-use and land-cover mapping

Journal Articles & Books
Décembre, 2013

Increasing the accuracy of thematic maps produced through the process of image classification has been a hot topic in remote sensing. For this aim, various strategies, classifiers, improvements, and their combinations have been suggested in the literature. Ensembles that combine the prediction of individual classifiers with weights based on the estimated prediction accuracies are strategies aiming to improve the classifier performances.

Environmental assessment tools for multi-scale land resources information systems. A case study of Rwanda

Journal Articles & Books
Décembre, 2006
Rwanda

Sustainable land use planning involves both policy- and farmer-oriented agricultural land use strategies. In this paper, a spatially and temporally explicit multi-scale decision support system that reveals the biophysical indicators affecting land use choices of these different stakeholders, is explained and demonstrated. It comprises three different environmental assessment tools, designed to run with data supplied by traditional soil surveys and organised into a land resources information system.

Monitoring land use and land cover change using remote sensing, markov analysis, population and landscape metrics analysis : a case study from Çanakkale (1987-2010)

Policy Papers & Briefs
Décembre, 2013
Turquie

Population growth in cities along with migration from rural areas dramatically increases the Land Use and Land Cover (LULC) changes. This study was conducted in Çanakkale province consisting of central part and its vicinities where rapid population growth and development have been taken place. This study aimed to determine LULC changes using remotely sensed data and geographical information system (GIS) techniques between 1987 and 2010.
