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.

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.

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.

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.

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.

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.

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.

A way of negotiation for decisions about land use planning and environmental management."Gond thinking" in matters of environmental management and land use planning requires an appropriate mix of the integrative approach of decision makers and of the analytical approach of scientiste. This gond thinking should also meet the challenges of negotiation between institutions, enterprises and pressure groupe which all claim the statue of peers.
