Previous studies suggest that management intensity zoning systems, such as the triad approach, could allow Canada’s forest industry to maintain or increase timber harvest levels while simultaneously reducing its environmental impact. In most such studies, the zones are exogenously specified. In this study, we use a linear programming model to endogenously allocate forest land to management inte...

there are two approaches regarding environmental changes. one of the is ignoring them and continuing present trend in future, and the other is identifying these changes and preparing environmental management program in order to control their negative impacts and plan for the improvement of environmental condition. anzali international wetland is one of the protected wetlands in iran which is in...

In many developing countries, limiting factors for development of sustainable production systems include variability in agro-ecological and socio-economic conditions, poor access to geo-referenced data and information, and poor relationship between the civil society, researchers and decision makers. Working with Interactive Development Scenarios (IDS) models may provide a way to plan (agricultu...

Sage grouse (Centrocercus urophasiamus) occur in regions that are spatially diverse and temporally dynamic in western North America. During the past 130 years, significant changes in disturbance regimes have affected their habitat. Plant communities in existence today are unique from any other time period because of altered disturbance regimes, confounded by a continual change in climate. In so...

In this paper we develop a new approach for land leveling in order to improve the topology of a large area for irrigation or civil projects. The objective in proposed model is to minimize the total volume of cutting so that technical requirements of land leveling such as suitable slope and standard ratio of cutting to filling and maximum penstock point’s height are considered. We develop a warp...
