Planning for land use development, protection of good quality agricultural land, land degradation management and many other resource management issues requires reliable land resource information. Enhanced Resource Assessment (ERA) techniques were employed to rapidly assess and predict soil and landscape attributes throughout Cooloola Shire in South East Queensland. ERA uses landscape modelling ...

in developing countries, it is common to site (or locate) industries without environmental impact assessment. in this study the impacts of two food processing industries on land use and land capability, noise and vibration, environmentally sensitive areas and visual quality as environmental elements were investigated. the research method adopted was the investigative survey research approach (i...

BACKGROUND Aquatic and land based exercise are frequently prescribed to maintain function for people with arthritis. The relative efficacy of these rehabilitation strategies for this population has not been established.This review investigated the effects of aquatic compared to land based exercise on function, mobility or participants' perception of programs for people with arthritis. METHODS...

Recently, special attention has been paid to artificial groundwater recharge in water resource management in arid and semi-arid regions. Water resources distribution in these regions is extremely uneven, both in spatial and temporal forms and groundwater is the only water resource and is a major constraint on economic and social development. Artificial groundwater recharge is considered an appr...

The objective of this investigation was assessment of physical and chemical parameters ofsoil and sediment in loess lands under different land uses, in the north of Iran. A yearly soilsampling was carried out randomly in three land uses (cultivated, forest and pasture) inQarnave and Yelcheshme watersheds. Sediment samples were taken monthly in thewatersheds at the hydrometrical station of Tamer...

An ecological land classification was developed for a complex region in southern California using geographic information system techniques of map overlay and contingency table analysis. Land classes were identified by mutual information analysis of vegetation pattern in relation to other mapped environmental variables. The analysis was weakened by map errors, especially errors in the digital el...

abstract in this study the effects of land use changes from pasturelands to croplands on soil microbiological and biochemical properties were studied in kangaver, dehno and soltanye regions. composite soil samples from 0-20 and 20-40 cm depths of pasture and cultivated lands were taken from kangaver, dehno and soltanye regions, and soil microbial respiration, microbial biomass c and n, and urea...

This paper is a good example of how solid research can support the policy decision process. Based on housing and land transaction data, the authors use the hedonic approach to calculate constant quality housing price and land price indices in 35 Chinese cities. This new and unique dataset on residential land transactions at the city level is by itself an important contribution, and the statisti...

[1] The inhibition of biogenic isoprene emission by elevated CO2 as observed in many plant taxa may significantly alter the sensitivity of air quality to global changes. We use a one-way coupled modeling framework to perform simulations under various combinations of 2000 to 2050 changes in climate, natural vegetation, anthropogenic emissions and land use to examine the effect of the CO2-isopren...
