The spatio-temporal variation underlies and complicates studies related to earth surface processes. Subsequent to our previous studies reporting the temporal invariability of sediment concentration, this study further reports the spatial invariability of sediment concentration or the flow–sediment relationship in the hilly part of the Chinese Loess Plateau. The dense channel network dissects this area into numerous sub-watersheds, which are composed of entire slopes (a combination of the hill slope and the valley side slope).

In September of 1996, without prior warning to Utah residents, the Clinton Administration announced the creation of the Grand Staircase-Escalante National Monument (GSENM) in southern Utah. Reactions by residents in neighboring gateway communities were both swift and intense. Lack of citizen input in the process drew ire among Utah citizens living near the monument and statewide. In this article we examine how the designation process has impacted residents’ trust in the federal agency managing the monument—the Bureau of Land Management.

Phosphorus deficiency is one of the largest constraints to crop production in tropical African soils owing to low native soil P and the high P fixation capacity of highly weathered soils. To achieve better soil P management, it is necessary to evaluate the effects of land management on soil P dynamics and P budget. We conducted a 4-year cultivation experiment in two dry tropical croplands in Tanzania at two sites with contrasting soil textures, viz. clayey and sandy.

This paper explores how environmental policy is implemented and enacted through the management of technical and institutional knowledge at the local level. We use the conservation of the freshwater pearl mussel in the River Esk, North Yorkshire, UK, as an empirical case study to examine the interaction that takes place between professionals from different institutional and disciplinary backgrounds as they come together to work on a common problem. We focus on two aspects: the way in which an institutional context was created; and the interaction between the professionals involved.

The art and science of developing effective policies and practices to enhance sustainability and adapt to new climate conditions on rangelands and savannas are typically founded on addressing the “average” or “typical” resource user. However, this assumption is flawed since it does not appreciate the extent of diversity among resource users; it risks that strategies will be irrelevant for many people and ignored, and that the grazing resource itself will remain unprotected. Understanding social heterogeneity is vital for effective natural resource management.

Livestock often concentrate grazing in particular regions of landscapes while partly or wholly avoiding other regions. Dispersing livestock from the heavily grazed regions is a central challenge in grazing land management. Position data gathered from GPS-collared livestock hold potential for increasing knowledge of factors driving livestock aggregation patterns, but advances in gathering the data have outpaced advancements in analyzing and learning from it.

This article investigates how cultural landscapes (especially the potentially limiting organically evolved landscape) can be used as a research framework to evaluate historical mining heritage sites in Australia and New Zealand. We argue that when mining heritage sites are read as evolved organic landscapes and linked to the surrounding forested and hedged farmland, the disruptive aspects of mining are masked. Cultural landscape is now a separate listing for World Heritage sites and includes associative and designed landscape as well as those that have evolved organically.

Segmentation of landholders has rarely been undertaken in the natural resource management literature, yet it provides a rich set of information for planners to improve targeting of public investment and resources. Segmentation allows the identification of segments of landholders that are ‘investment ready’, their location and characteristics, and the land conservation incentive programmes that they would be most willing to participate in. Segments that are not investment ready are also identified, and the instances where they reside in critical ecological habitats.

High biodiversity of Estonian semi-natural grasslands can only be maintained through continuous management. One option for the usage of biomass from these areas is bioenergy production, if both the herbaceous biomass yield and the chemical characteristics of the cut meet the needs. In 2007 the largest average annual biomass yield per area was achieved in floodplain meadows (5.7tdrymass/ha), which also have the highest potential for biomass production among Estonian semi-natural grasslands (more than 113,000tdrymass).

In the conditions of the Republic of Belarus there was shown the necessity of detection and recording of socially-significant sights and brand objects in the process of managing land resources. There was examined the classification of land plots and objects of real estate, which appear to be territory brands. There were determined the main approaches to the formation of the system of such objects on the basic level of state management.
