The suitable spectral mode in remote sensing is often desirable to facilitate the inversion of ecological environment and landscape. This paper put forward an optimizing model based on variable precision rough sets (VPRS) for the land cover discrimination in wetland inventory. In the case study of Lake Baiyangdian which has important ecological functions to the northern China, this model is established successfully according to the domain-experts knowledge. The procedure is as follows.
evaluation of West Virginia's Managed Timberland Tax Incentive Program
Preferential property tax treatment of forested land is part of legislative policy in all 50 states. West Virginia's Managed Timberland (Managed Timberland) is designed to retain private forest land in forested use. In West Virginia, although private forest land owners hold 9.7million acres of forest land (83% of forest land), Managed Timberland enrolled acres have remained at approximately 2million acres since 1998. This lack of enrollment may be a cause for concern regarding the success and benefits of the program.
Improving communication among stakeholders through ex-post transactional analysis -- case study on Romanian forestry
One of the most visible components of the Forestry Development Project, carried out between 2003 and 2009 by the World Bank and Romanian Government was “PR support, Awareness Campaign and Development of PR products”, meant to improve the communication between all stakeholders involved in sustainable forest management. The awareness campaign mainly consisted of nine meetings with the forest owners and nine workshops with all stakeholders, i.e.
Influence of land use on organic carbon pool and chemical properties of Vertic Cambisols in central and southern Italy
Land use strongly influences soil properties and unsuitable practices lead to degradation of soil and environmental quality. The aim of this study was to assess the impact of different land uses on some chemical properties of soils developed from Pliocene clays, within hilly environments of central and southern Italy. The areas investigated are located in Vicarello di Volterra (Pisa, Tuscany), S. Quirico d'Orcia (Siena, Tuscany) and Soveria Simeri (Catanzaro, Calabria).
Farmers’ assessment of soil quality in rice production systems
In the recent past there has been increasing recognition that local knowledge of farmers can yield insight into soil quality. With regard to constraints and possibilities for the production of irrigated rice in the south of Brazil there is no documentation on local soil knowledge. The goals of this study were to answer the following questions: (1) Which soil quality perceptions do rice farmers have? (2) Which soil quality indicators are most important to them?
