    There is a trend to acquire high accuracy land-cover maps using multi-source classification methods, most of which are based on data fusion, especially pixel- or feature-level fusions. A probabilistic graphical model (PGM) approach is proposed in this research for 30 m resolution land-cover mapping with multi-temporal Landsat and MODerate Resolution Imaging Spectroradiometer (MODIS) data. Independent classifiers were applied to two single-date Landsat 8 scenes and the MODIS time-series data, respectively, for probability estimation. A PGM was created for each pixel in Landsat 8 data.

    Mangroves are valuable socio-ecological ecosystems that provide vital goods and services to millions of people, including wood, a renewable natural capital, which is the primary source of energy and construction material for several coastal communities in developing countries. Unfortunately, mangrove loss and degradation occur at alarming rates. Regardless of the protection and close monitoring of mangrove ecosystems in Mexico during the last two decades, mangrove degradation and the loss of biodiversity is still ongoing.

    The main purpose of this paper is to carry out an analysis of the agricultural land market in Poland based on market transactions conducted in 2002. Authors analysed the sale and lease market of agricutural land making an allowance for its ownership structure. The analysis was made both on the private market and toward the land owned by the State Treasury and managed by the Agency of the Agricultural Propety of the State Treasury (since July 16, 2003 transformed into the Agricultural Property Agency).

    Bolivia, United States of America

    Despite the implementation of Bolivia's land reform in 1953, the agrarian structure continues to have an extreme concentration of land. Furthermore, in the last two decades regional agrarian structure have been aggravated by population pressures and a lack of new technological practices for most small scale farmers and peasants. Public and private institutions and urban residents observe hundreds of landless and near-landless families in the cities searching for jobs. Most end up becoming part of the growing unemployed labor force in the urban sector.

    From the advent of the application of satellite imagery to land cover mapping, one of the growing areas of research interest has been in the area of image classification. Image classifiers are algorithms used to extract land cover information from satellite imagery. Most of the initial research has focussed on the development and application of algorithms to better existing and emerging classifiers. In this paper, a paradigm shift is proposed whereby a committee of classifiers is used to determine the final classification output.

    Declines in global biodiversity due to land conversion and habitat loss are driving a "Sixth Mass Extinction" and many countries currently fall short of meeting even nominal land protection targets to mitigate this crisis. Here, we quantify the potential contribution of Indigenous lands to biodiversity conservation using case studies of Australia, Brazil and Canada. Indigenous lands in each country are slightly more species rich than existing protected areas and, in Brazil and Canada, support more threatened species than existing protected areas or random sites.

    This is the first paper that estimates the global land use change impact of growth of the bioenergy sector. Applying time-series analytical mechanisms to fuel, biofuel and agricultural commodity prices and production, we estimate the long-rung relationship between energy prices, bioenergy production and the global land use change. Our results suggest that rising energy prices and bioenergy production significantly contribute to the global land use change both through the direct and indirect land use change impact.

    This is the rst paper that estimates the global land use change impact of growth of the bioenergy sector. Applying time-series analytical mechanisms to fuel, biofuel and agricultural commodity prices and production, we estimate the long-rung relationship between energy prices, bioenergy production and the global land use change. Our results suggest that rising energy prices and bioenergy production signicantly contribute to the global land use change both through the direct and indirect land use change impact.
