Displaying 726 - 730 of 1605functional evaluation of three indicator sets for assessing soil quality
Efforts to define and quantify soil quality are not new, but establishing consensus about a set of standardized indicators remains difficult. Also, the view of land managers is usually not taken into account when evaluating various sets of indicators. Our objective was to compare, in functional terms, soil quality assessments based on 29 indicators, a subset with 8 of those indicators, and 4 indicators selected independently by farmers, based on their perceptions of soil quality.
Water quality in agricultural lands draining to the Great Barrier Reef: A review of causes, management and priorities
The environmental consequences of agriculture are of growing concern. One example of these consequences is the effect of agricultural pollutants on the Great Barrier Reef (GBR), a world heritage-listed ecosystem lying off the tropical north-eastern coast of Australia. Pollutants from agricultural lands (fine sediments and attached nitrogen (N) mainly from grazing lands, and dissolved N and pesticides mainly from cropping) in catchments draining into the GBR lagoon threaten the health and resilience of this ecosystem.
Management of natural resources and protection of the coastal urban area of Glyfada
This survey concerns the urban coastal environment of Glyfada. Due to its wonderful natural resources, the area has been chosen for residence, business, tourism as well as recreation and entertainment. However, these natural resources are threatened by degradation due to an increasing intensity of land uses and various policies that have been implemented. The survey focuses on the problems this area faces and the possibilities to maintain or increase the quality of natural resources.
Land use determines interest in conservation easements among private landowners
Protection of private lands through conservation easements has garnered recent attention from scientists and conservation practitioners. Questions remain, however, about the specific characteristics and activities driving landowners’ interest in conservation easements and their willingness to consider granting them. Resolving these questions could improve prospects for private land conservation by helping land conservation organizations identify and better understand potential easement grantors.
Patterns and causes of land change: Empirical results and conceptual considerations derived from a case study in the Swabian Alb, Germany
Land-use and land-cover change profoundly affect human well-being and, therefore, have become a major topic for society. A thorough understanding of past and present processes transforming landscapes is essential for guiding future developments toward the sustained provision of the ecosystem services humans critically depend upon. Drawing on the driving forces and resilience frameworks, we identify possible variables and patterns of land change, connecting them to empirical findings in three case study areas in the Swabian Alb region, southwestern Germany.
