Eco-economic aspects of sustainable agricultural land use

Journal Articles & Books
Décembre, 2013
Fédération de Russie

Sustainability of agricultural land use is determined by economic and environmental characteristics of land resources. The method for land use assessing, which enables to determine the type of its environmental and economic status (EES), was developed. The method includes the calculation of performance indicators, drafting the scale and the determination of the cumulative EES for land.

Assessing Transportation Infrastructure Impacts on Rangelands: Test of a Standard Rangeland Assessment Protocol

Journal Articles & Books
Décembre, 2010

Linear disturbances associated with on- and off-road vehicle use on rangelands has increased dramatically throughout the world in recent decades. This increase is due to a variety of factors including increased availability of all-terrain vehicles, infrastructure development (oil, gas, renewable energy, and ex-urban), and recreational activities.

Revolutionary Land Use Change in the 21st Century: Is (Rangeland) Science Relevant?

Journal Articles & Books
Décembre, 2012

Rapidly increasing demand for food, fiber, and fuel together with new technologies and the mobility of global capital are driving revolutionary changes in land use throughout the world. Efforts to increase land productivity include conversion of millions of hectares of rangelands to crop production, including many marginal lands with low resistance and resilience to degradation. Sustaining the productivity of these lands requires careful land use planning and innovative management systems.

Do Native Warm-season Grasslands Near Airports Increase Bird Strike Hazards?

Journal Articles & Books
Décembre, 2013

Bird aircraft collisions (bird strikes) are a recognized safety hazard and land uses that attract birds hazardous to aircraft should be avoided on and near airports. Many airfields contain large areas of anthropogenic grassland habitats, often dominated by cool season grasses. Land managed as native warm season grasses (NWSG) potentially could increase bird strike hazards on and near airports by attracting hazardous birds and harboring small mammals that are prey for hazardous raptors.

Assessing the effect of alternative land uses in the provision of water resources: Evidence and policy implications from southern Europe

Journal Articles & Books
Décembre, 2012
Europe

Ecosystem goods and services have been brought to the forefront of policy making all over the world. It is acknowledged that these goods and services underpin human well-being. The provision of water resources is amongst those services that have raised more attention, given its unquestionable value and global threats like climatic change. Nevertheless, the biophysical basis that determines the land-use/water interactions has been often ignored. For the formulation of sound decisions, it is necessary to extend the empirical basis that determines these complex relations.

Baobab (Adansonia digitata L.) fruit production in communal and conservation land-use types in Southern Africa

Amérique septentrionale
Europe

Baobab fruit are harvested and used throughout Africa as an important source of food and are sold to generate income. Commercial use is increasing rapidly as derivatives of the fruit such as baobab seed oil and fruit pulp are being exported to Europe and North America. The cash derived from the sale of fruit support thousands of rural people. This study examines baobab fruit yields in an area being harvested for commercial use.

Effect of Land Use on Soil Degradation and Soil Productivity Decline on Alfisols and Ultisols in Ogun State in South Western, Nigeria

Journal Articles & Books
Mars, 2010
Nigéria

One of the critical factors influencing land degradation is land use. However, the extent to which land use influences land degradation has not been fully ascertained in the southwestern part of Nigeria (i.e. particularly in Ogun State). Thus, this study was designed to assess the extent to which land use influences crop productivity in Ogun State. Two major soil types identified at the site were Alfisols and Ultisols. Within these, three land use types (LUT) were identified: arable crop - Land Use 1, cash crop production - Land Use 2, and non-agricultural use – Land Use 3.

Determining misuse of agricultural lands in Yenimahalle district of Ankara using GIS and remote sensing techniques

Policy Papers & Briefs
Décembre, 2012

This study is carried out to determine land use changes by Geographic Information Systems and Remote sensing methods in Yenimahalle district of Ankara province. Changes in land use were identified between 2000-2005 and 2000-2010. For the study Landsat-5 image of year 2000, Ikonos image of year 2005, and SPOT image of year 2010 were used. 1:25000 scale topo maps and soil maps, and CORINE land use data were also used. GPS data collected from field were used for ground truth studies.

Toward a Sustainable Utilization of Land Resources in China: Problems, Policies, and Practices

Journal Articles & Books
Décembre, 2014
Chine

China’s economy is growing explosively with double-digit rates of growth. However, behind the scenes of this economic miracle, a dark underbelly exists. The potential impact of the unsustainable use of land resources is increasing. Each parcel of land has a stationary geographic location, while its utilization is optional. The re-adjustment and optimization of land use patterns ought to be encouraged.

Processing tomato water and nutrient integrated crop management: state of the art and future horizons

Journal Articles & Books
Décembre, 2003
États-Unis d'Amérique

Growing processing tomatoes represents one of the most intensive forms of land use in terms of water consumption and nutrient inputs. During the last decade in many European countries and in the United States, Integrated Crop Management guidelines have also been applied for fertilisation and reducing nitrogen inputs to crops has become compulsory. A large number of Best Management Practices, rules and tools have been developed to steer farmers toward sustainable farming practices.

Evaluating the Impact of Distance Measures on Deforestation Simulations in the Fluvial Landscapes of Amazonia

Journal Articles & Books
Décembre, 2014

Land use and land cover change (LUCC) models frequently employ different accessibility measures as a proxy for human influence on land change processes. Here, we simulate deforestation in Peruvian Amazonia and evaluate different accessibility measures as LUCC model inputs. We demonstrate how the selection, and different combinations, of accessibility measures impact simulation results. Out of the individual measures, time distance to market center catches the essential aspects of accessibility in our study area.

Emergy-based evaluation of peri-urban ecosystem services

Global

Peri-urban areas are often characterized by valuable natural environments that provide essential life-support functions and ecosystem services for urban residents. Global environmental change has raised concerns over how urbanization and land use and land cover change affect ecosystem services. This study applied systems ecology theory and ecological energetic analysis to value the worth of natural environment and ecosystem services to a socioeconomic system. We begin with a general discussion of peri-urban areas and their ecosystem services.
