    Increase in use of biomass as renewable source of energy in Europe is tightly linked to the policies aimed at mitigation of climate changes i.e. reductions of greenhouse gas emissions. Both for assessment of the carbon sequestration and emissions as well as for assessment of potential amounts of biomass for renewable energy, information of land cover dynamics are essential. Therefore, the aim of our study was to improve accuracy of estimates of the land use changes in the time period between 1990 and 2014.

    The study represents results on remote sensing methods based evaluation of land use and land use changes in former and existing peat extraction areas in Latvia. The aim of the study is to elaborate activity data set for the National GHG inventory for the wetlands remaining wetlands for peat extraction. The study results provide sufficient data for application of the default emission factors for the peat extraction sites and flooded lands.

    degradação de terras

    The degradation of soils with high sand content, in the southwest of the state of Rio Grande do Sul, is due to the vegetal cover withdrawal, forming sandy areas called "areais", which pose a risk to animal husbandry and the prairie ecosystem. A technique of revegetation with cover crops such as Avena strigosa Schieb. and Lupinus albescens H. et Arn., was developed to reduce the soil particle movement by eolic erosion.

    sistema de informação geográfica

    Phosphorus (P) and nitrogen (N) concentrations were measured at 75 points in the upper reaches of rivers draining into the agricultural watersheds south of the Ibaraki prefecture during the summer and winter of year 2009. A geographic information system (GIS) was used to combine the environmental information regarding the watersheds such as land use, topography, and soil with water quality data for a statistical analysis. As andosols have a stronger tendency to adsorb P than other soil types, watersheds were classified into areas with andosol and non-andosol soils.

    The article presents the analysis of the Associations of Gardeners of Lithuania as well as the undergoing changes in their territories. The objective of the article is to discuss the current situation in the territories allocated to the amateur gardens and to assess the current issues concerning the land use and management. The associations of gardeners have encountered a great number of problems concerning the territorial planning, engineering communication services and services maintaining the needs of the associations, the expansion as well as development of these areas.

    The land use pattern is affected by different factors. One group of factors related to studies of land use change are socio-economics. The aim of the study is to test if the various indicators describing local government capacity have any impact on changes in arable land use. The study focuses on Estonian rural municipalities. The first task was determination of land use changes for the period 2009-2015. The GIS overlay technique was implemented for this. The second task was a correlation analysis among indicators of changes in arable land use and indicators of local government capacity.
