Throughout the Amazon region, the age of forests regenerating on previously deforested land is determined, in part, by the periods of active land use prior to abandonment and the frequency of reclearance of regrowth, both of which can be quantified by comparing time-series of Landsat sensor da...
Land use is a categorical regionalised variable returning the main socio-economic role each location has, where the role is inferred from the pattern of occupation of land. There are two main uncertainties surrounding land use data, positional and categorical. This paper focuses on the second ...

Estimates of nitrogen and phosphorus loading for manure and commercial fertilizer sources based on county statistics and agricultural application rates were used with digital land-use and land-cover data derived from satellite imagery to further distribute the estimated nutrient loading within agricultural ...
In this paper we investigate determinants of land use decisions made by farmers in an upland area of the Philippines. Our goal is to quantify land use responses to economic signals, especially agricultural prices, and thereby to shed light on the impacts of policies affecting such prices. We us...

Land-use change is one of the biggest threats to biodiversity globally. The effects of land use on biodiversity manifest primarily at local scales which are not captured by the coarse spatial grain of current global land-use mapping. Assessments of land-use impacts on biodiversity across large sp...
The present paper deals with a model developed and used at the Danish Ministry of Agriculture, Bureau of Land Data, for calculation of the amount of water needed for irrigation. The model incorporates information on soil types and their geographical distribution, soil water retention and root devel...
Land use and land cover map of Shingla river basin for the year 1975 using Landsat 1 (MSS) satellite data. The map was generated in Quantum GIS using Semi Automatic Classification Plugin (SCP). Shingla river basin (SRB) is drained by river Shingla and the adjoining streams. SRB is a ...
