Relationships between Danish organic farming and landscape composition

Dezembro, 2007
Dinamarca

This article presents an investigation of relationships between organic farming and landscape composition in Denmark. Landscape composition was analysed in terms of density of uncultivated landscape elements (I), number of land uses per hectare (II), diversity of land use (III) and mean field size (IV). Two analytical approaches were used. The first was based on an examination of the national agricultural registers for 1998, 2001 and 2004.

Optimal conservation planning of multiple hydrological ecosystem services under land use and climate changes in Teshio river watershed, northernmost of Japan

Journal Articles & Books

Japão

Most anthropogenic activities impacted on water quality and quantity, and further impacted on ecosystem services (ESs) in watershed are related to land use and climate changes those may cause losses of ecosystem functions. Effective information regarding ESs and their optimal priority conservation planning responded to land use and climate changes provide useful support for diverse stakeholders in ESs planning, management and policies.

Assessment, modelling and management of land use and water quality in the upper Taieri River catchment

Journal Articles & Books
Dezembro, 2013

An average of 16 years' data at sites in the upper Taireri River catchment was used to determine if water quality had changed commensurate with an increase in the irrigated area and land-use change. To help remediate perceived gaps in the nutrient modelling software Overseer®, data was also collected from a low-intensity border dyke and high-intensity spray-irrigated property. Filterable reactive phosphorus concentrations increased over time and were attributed to the irrigation of poor anion storage capacity (ASC) soils and irrigation-return flows.

new model for sustainable development: a case study of The Great Bear Rainforest regional plan

Journal Articles & Books
Dezembro, 2010
Canadá

This paper describes a new model of sustainable development planning based on a case study of a successful planning process for the Great Bear Rainforest on Canada's west coast. The planning region is an area of international ecological significance that contains one-quarter of the world's remaining ancient coastal temperate rainforest. An innovative collaborative planning process was initiated in 1996 to develop a plan for the region that balances social, economic, and environmental values.

Soil fertility and its significance to crop productivity and sustainability in typical agroecosystem: a summary of long-term fertilizer experiments in China

Journal Articles & Books

China

AIMS AND BACKGROUND: Soil fertility quality index is a useful indicator that helps to improve sustainable land use management and achieve economical yield in agriculture production. The objectives of this study were to evaluate the changes of soil fertility quality between the 1980s and 2000s in different cropping systems and its significance to crop productivity and sustainability.

Automatic greenhouse delineation from QuickBird and Ikonos satellite images

Journal Articles & Books
Dezembro, 2009

The area of production under greenhouses has been in rapid growth in recent years, and at present there are over 500,000ha scattered all over the world. Due to the vast amount of inputs (water, fertilizers, fuel, etc.) required, and outputs of various agricultural residues (vegetable waste, plastic sheeting, phytosanitary product containers, etc.), the impact of this type of production system to the environment is considerable in particular if pursued without a sound and sustainable territorial planning.

Assessment of rural community and agricultural development using geomorphological–geological factors and GIS in the Trikala prefecture (Central Greece)

Journal Articles & Books
Dezembro, 2013

In this study, the potential land use planning for rural communities and agricultural development is examined with a multi-criteria analysis and Geographical Information System. For this purpose, geological, geomorphological and socio-economic data and natural hazard maps were chosen as major factors affecting both land uses. The Analytical Hierarchical Process method was applied to evaluate these factors and the uncertainty of their weight alterations estimated.

coherent set of future land use change scenarios for Europe

Suíça
Noruega
Europa

This paper presents a range of future, spatially explicit, land use change scenarios for the EU15, Norway and Switzerland based on an interpretation of the global storylines of the Intergovernmental Panel on Climate Change (IPCC) that are presented in the special report on emissions scenarios (SRES). The methodology is based on a qualitative interpretation of the SRES storylines for the European region, an estimation of the aggregate totals of land use change using various land use change models and the allocation of these aggregate quantities in space using spatially explicit rules.

Estimating effects of an urban growth boundary on land development

Journal Articles & Books
Dezembro, 2006

This study estimates the effects of an urban growth boundary (UGB) on land development decisions in Knox County, TN, using a heteroscedastic probit model. With combined effects of increased land development within the city boundary and decreased development within the UGB and the neighboring town of Farragut after the implementation of UGB, the UGB of Knox County has been successful in urban revitalization within the city boundary and discouraging urban sprawl.

Grazing intensity is a poor indicator of waterborne Escherichia coli O157 activity

Journal Articles & Books
Dezembro, 2011

Contamination of watercourses with fecal matter represents a significant risk to public health due to the associated risk from human pathogens (e.g. Escherichia coli O157, norovirus). In addition, water contamination may also perpetuate the re-infection cycle of human pathogens within domesticated and wild animal populations. While diffuse pollution from agricultural fields has been identified as a major source of these pathogens, the relationship between livestock grazing intensity and subsequent pathogen persistence in water is not well established.
