Atemporal and intertemporal use of public lands, the determination of optimal levels of wilderness designation and habitat preservation, and the appropriate regulation of natural resources have all been "hot button" issues in the American West for quite some time now. In this paper, I propose and describe a research agenda which promises to yield interesting and useful new policy insights into these fractious resource issues.

We used the process-oriented niche model CLIMEX to estimate the potential global distribution of serrated tussock under projected future climates. Serrated tussock is a drought-tolerant, wind- and human-dispersed grass of South American origin that has invaded pastures in Australia, Europe, New Zealand, and South Africa. The likely effect of climate change on its potential global distribution was assessed by applying six climate-change scenarios to a previously developed model.

Food security remains an ongoing global concern: the challenge of ensuring food availability, access, and utility for all, at all times, is yet to be met. The body of literature relating to food security is growing immensely. Land administrators are part of the discourse. Their arguments are spread disparately across academic and professional publications. The distinction between scientific work and political rhetoric is increasingly blurry: the role of land administration needs to be more concisely articulated.

Arsenic concentrations are reported for the

Climate change and energy saving are challenging the city and the territorial organization. Innovative spatial and urban planning methods and procedures are required, and new approaches and instruments must be elaborated and applied in order to shift from the building scale to the urban and territorial ones.

Still, more agricultural land is getting abandoned in Slovenia, specially in less favored areas. Such process of degradation of fertile land is most intensively present in the Obalno-kraska region and Goriska. Similar happens with grassland in mountain region as less and less animals which are suitable for that region are bred there. To prevent brush encroachment and to start recultivation of aban

A consequence of the European colonization of Australia has been a significant ioss of biodiversity: one in four mammal species is either extinct or threatened. In contrast, only one species of bird has been lost from the Australian continent and there is less concern for the survival of the Australian avifauna than for mammals. This is despite the fact that nearly one in five bird species is listed as threatened or of “special concern”.

The effect of shallow water table fluctuations on the evaporation and CO₂ fluxes in a peatland is investigated. The fluxes of evaporation and net ecosystem exchange of carbon were measured from mid-spring to the end of summer in 2005 and 2006 and simulated independently with process models. The observed and modelled data were then compared along a gradient of water levels. Any variation along the gradient would imply an influence of the water table on the flux. It became evident that changes in the water table had no effect on the evaporation and CO₂ fluxes of the peatland.

Complex changes in carbon sources and sinks caused by rapid urbanization have been observed with extensive changes in the quantity, structure, and spatial pattern of land use types. Based on the modified Carnegie-Ames-Stanford Approach model and on gray relational analysis, we analyzed the influence of land use changes on carbon sinks and emissions in Guangzhou from 2000 to 2012. The aim was to identify suitable options for built-up land expansion that would allow for minimal carbon losses.

In September of 1994, the Army closed the Fort Ord Military Reservation, a Superfund site of some 28,000 acres located in Monterey County, California. Under the Base Closure and Realignment Act, nearly all of this land will be transferred to federal and state entities and to a number of cities of the Monterey peninsula that border the base. A good deal of this property is valuable real estate -- coastal dunes, golf courses, and barracks that can be converted to apartments or dormitories.

The mountains of northern Vietnam have lost significant forest cover during the last decades due to the conversion from natural vegetation to cultivated land, leading to the depletion of soil organic matter and land degradation. The study evaluated bamboo as an alternative cropping strategy in the northern central upland of Vietnam. We analyzed above-ground carbon fixing capacity of bamboo, accumulation of soil organic carbon, and socio-economic aspects as compared to other land use systems.
