Although there are efforts underway to educate the public on landscape planning and land management, educational efforts geared toward children have been limited. This study recognizes the importance of landscape planning education, children's inherent spatial cognition, and their observational and creative skills. However, there are limited opportunities for children to be landscape planners and the elements children believe are important in the design and planning of their ideal community are unknown.

Geomorphologic and hydrologic research heavily depends on digital elevation models (DEM) which are currently being prepared from digital contours. The present study examines the use and applicability of freely available global elevation data source (3 arc seconds finished Shuttle Radar Topography Mission (SRTM)) in landform characterisation, geomorphometry, river basin studies and other allied scientific applications in comparison with contour elevation data derived from the surveyed topographical sheets.

A new grid-based model of nutrient dynamics and transport process has been developed within a distributed hydrological modelling framework and integrated with river network module. The key aspect of this development is a process based description of nutrient generation process on the land surface and its related nutrient release with hydrologic runoff and soil erosion.

Desertification, caused by land degradation as opposed to the immediate creation of classical deserts, is of prime concern in the 21st century. As a result of human activities and climate change, the land loses its proper hydrologic function and biological productivity. Desertification affects 33 % of the earth's surface and over a billion people. Fire-related desertification has a number of environmental, social, and economic consequences. The two key environmental consequences are soil erosion and non-native plant invasions. Erosion after wildland fires can be in the range of

The tropics of northern Australia have received relatively little attention with regard to the impact of soil erosion on the many large river systems that are an important part of Australia's water resource, especially given the high potential for erosion when long dry seasons are followed by intense wet season rain. Here we use ¹³⁷Cs concentrations to determine the erosion processes supplying sediment to two major northern Australian Rivers; the Daly River (Northern Territory), and the Mitchell River (Queensland).

In Ireland fertilised grasslands are major source of nitrous oxide (N₂O), a powerful greenhouse gas. We present 5 years (2004-2008) of eddy-covariance (EC) observations of N₂O fluxes from an ecosystem transitioning from wet managed grassland to a broadleaf forestry. One sector of the EC footprint was converted to forestry during the observation period, while the remainder of the footprint remained under intensively managed grassland.

Relationships among biological indicators of soil quality and organic matter characteristics were evaluated across a continuum of long-term agricultural practices in Missouri, USA. In addition to chemical and physical soil quality indicators, dehydrogenase and phenol oxidase activity were measured, ¹³C nuclear magnetic resonance (¹³C NMR) and diffuse reflectance Fourier transform (DRIFT) spectra of soil organic matter were collected, and visible, near-infrared reflectance (VNIR) spectra of whole soil were collected.

Global defense spending is $US1753 billion annually or approximately 2.5% of the world GDP. Significant time and resources is spent in training 28 million defense personnel worldwide. Much of this training on land takes place within specifically designated military training areas (MTAs). Globally, the size of the MTA estate is likely to be very large, but just how large is unknown. Our preliminary analyses has identified that MTAs cover at least 1% of the Earth's surface.

Mosaic burning is the deliberate creation of a mosaic of patches representing different fire histories. It is often recommended for management of Australia’s natural landscapes, on the assumption that it enhances biodiversity and reduces fire hazard through increased spatial and temporal diversity of fuel loads and species composition. It is also suggested that such fire practices were used throughout Australia by traditionally living Aboriginal people.

In rural areas, land use and cover change is often the cumulative result of individual farmer decisions. The goal was to construct a spatial typology of farming systems and assess their influence on the extent and spatial distribution of deforestation, forest re-growth, and agriculture expansion in southern Chile between 1999 and 2007. We present a farm typology and its spatial rendering through the combination of farm-cadastral information and land cover and change data. Using multivariate statistical methods, four types were identified.

Robust emission inventories of atmospheric pollutants are critical to understanding and predicting impacts, identifying key sources and mitigation opportunities.
