Human activities have created high nutrient surpluses in agricultural lands due to the increasing rate of chemical fertilizer application and the increase in livestock production. To analyse the nutrient characteristics and estimate the nutrient load in streams, we conducted extensive field survey and water quality experiments from 2007 to 2008 in Koise River, a major river of the Lake Kasumigaura watershed, Japan. Water quality indicators of total nitrogen (TN), total phosphorus (TP) and total organic carbon (TOC) were investigated.
Erosion modelling for land management in the Tahoe basin, USA: scaling from plots to forest catchments
Land management and its effects on water quality are a concern where regulatory agencies work to establish sediment and/or nutrient loadings. Runoff and erosion measurement in the field and modelling at the catchment scale are often the only means of generating realistic data and results for subsequent analyses. As such, it is critical to link local-scale field measurements associated with the range of land uses or soil restoration efforts with the catchment-scale sediment loading.
Comparing spatiotemporal patterns in Eurasian FPAR derived from two NDVI-based methods
A long-term, consistent Fraction of Absorbed Photosynthetically Active Radiation (FPAR) product is necessary to study the spatial and temporal patterns of vegetation dynamics associated with climatic changes and human activities. In this study, Eurasia was selected as the study area.
Assessing the Utility of Satellite Imagery with Differing Spatial Resolutions for Deriving Proxy Measures of Slum Presence in Accra, Ghana
Little research has been conducted on how differing spatial resolutions or classification techniques affect image-driven identification and categorization of slum neighborhoods in developing nations. This study assesses the correlation between satellite-derived land cover and census-derived socioeconomic variables in Accra, Ghana to determine whether the relationship between these variables is altered with a change in spatial resolution or scale.
Global characterization and monitoring of forest cover using Landsat data: opportunities and challenges
The compilation of global Landsat data-sets and the ever-lowering costs of computing now make it feasible to monitor the Earth's land cover at Landsat resolutions of 30 m. In this article, we describe the methods to create global products of forest cover and cover change at Landsat resolutions. Nevertheless, there are many challenges in ensuring the creation of high-quality products. And we propose various ways in which the challenges can be overcome.
